Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

by a SLS Mechanism

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure
Key words gallium nitride (GaN) nanowires vapor-liquid-solid (VLS)

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Solid-state nanopores have attracted considerable attention in recent years due to
their promising applications in next-generation nanosensors for rapid electrical
detection and characterization of biomolecules However key to detect and
characterize DNA and biomolecules with single-molecule resolution is not only the
nanopore size but also the corresponding three-dimensional (3D) nanopore sidewall
shape The shape of sidewall is an important issue in the analysis of DNA
translocation through nanopore Here we demonstrated by using a low-intensity
electron beam to make nanoscale pores this technique is possible to control the 3D
shape of nanopore in the Si3N4 membranes In addition the electron tomography is a
powerful technique for characterizing nanoscale structures in three dimensions
Individual projection images of the tilt series are aligned with cross-correlation the
tomographic reconstruction is calculated by weighted back-projection These images
are used to investigate the dynamics of nanopore formation mechanism Furthermore
we introduce a novel fabrication technique to form metallic quantum dots devices
This device consists of a small disc sandwiched between top and bottom metallic
contacts The measurement result shows that the device is possible to resolve
well-defined electronic states as quantum dots behavior

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the
calcination temperature is at 550

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the
calcination temperature is at 550

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the
calcination temperature is at 550

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Monoclinic BiVO4 products were synthesized via a hydrothermal process used as a
template for the fabrication of Ag nanoparticle-doped BiVO4 (AgBiVO4) composite
products through a visible light reduction process The structures morphologies and
optical properties of the as-prepared products were characterized by X-ray powder
diffraction scanning electron microscopy transmission electron microscope
energy-dispersive X-ray spectroscopy and UVndashVis diffuse reflectance spectroscopy
Results showed the mass ratio of AgNO3 to BiVO4 and the illumination time of
visible light have great effect on the morphologies and optical properties of the
products The photocatalytic activities of the prepared products were examined by
studying the degradation of methylene blue (MB) solutions under visible light
irradiation (gt 420 nm) The results show clearly that the AgBiVO4 possess a higher
photocatalytic activity than pure BiVO4 and P25 due to its AgBiVO4 interfaces
Interestingly obviously enhancing photocatalytic activity (gt99 degradation within
30 min) was found on BiVO4 in aqueous AgNO3 solution (BiVO4Ag+) We
proposed a possible Z-scheme photocatalytic mechanism to understand the enhanced
photochemical properties In addition We use the AgBiVO4 application on
photocatalytic disinfection and the BiVO4 products possess potential of detecting Ag+
ions concentration in water by fluorescence analyses

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
In this study germanium nanowires (GeNWs) were grown directly from a
Au-deposited germanium (100) substrates by a solid-liquid-solid (SLS) mechanism in
the temperature range 550ordmC-650ordmC The GeNWs are grown by a self-assembly way
on the Au-coated germanium substrate at the atmospheric pressure of Ar ambience
Furthermore additional feedstock gas such as GeH4 is not needed during the
growth of GeNWs The surface morphology of GeNWs was characterized with
field-emission scanning electron microscope (FESEM) The diameter thickness and
structure of GeNWs were analyzed with transmission electron microscopy (TEM) and
the chemical compositions of GeNWs were determined by energy-dispersive
spectroscopy (EDS) The growth of GeNWs is very sensitive to the growth
temperature and GeNWs with excellent morphology and high surface density can be
successfully grown only over a limited temperature range (575ordmC-625ordmC) These long
thin and straight GeNWs have a high aspect ratio and are surrounded by an oxide
layer The composition of corresponding oxide layers is GeOx (xlt2) As the thickness
of Au film is decreased from 9 nm to 1 nm the average diameter of GeNWs
decreases from 1193 nm to 385 nm Our experimental results demonstrate that the
diameter of germanium nanowires can be controlled by the thickness of Au catalytic
film Key words germanium nanowires solid-liquid-solid

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the
calcination temperature is at 550

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳
導實驗結果發現添加BN確實有提升的效果添加比例為005wt的銲件明顯的提升約

welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ABSTRACT
The electrochemical dissolution rates and nanoscale films oxide of GaAs were
determined by the inductively coupled plasma technique (ICP) under illumination
Both X-ray wide angle diffraction (WAD) and glancing angle diffraction (GAD)
techniques were used Diffraction from only one lattice set in the matrix oxide was
detected in etching with H2SO4H2O solution by wide angle diffraction Each
diffraction line appeared as an interference pattern Glancing angle diffraction of
X-ray source ensured high sensitivity not only to investigate chemical composition
but also to characterize the structural features of the oxides The GaAs dissolution rate
in aqueous sulfuric acids solutions increased dramatically in the presence of H2O2
and the GaOOH phase was uniquely found on the oxidized surface It is postulated
that the production of GaOH2+
intermediate is thermodynamically favored so that the
dissolution rate of GaAs in H2SO4 system is accelerated by the present of H2O2 The
dissolution rate of GaAs in H2SO4 systems was low by ICP test under either
illumination or dark

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands
Keywords spin splitting magnetoresistance heterostructure cyclotron resonance

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Abstract
In this study a household microwave (MW)-assisted synthesis method for
preparation of fluorescent chicken egg white (CEW)-stabilized gold nanoclusters
(eggndash AuNCs) has been developed CEW was used as template and protector CEW
contains rich source of protein which lead to the formation of eggndashAuNCs Tyrosine
and tryptophan amino acid residues are responsible for the conversion of Au ions to
Au0 under alkaline condition Not only the reaction time can be shortened to five
minutes but the method confirms to the demand for the green chemistry due to the
superheating and non-thermal effects of the MW energy The as-prepared eggndashAuNCs
had red emission (λem=646 nm) when excited at 370 nm From high-resolution
transmission electron microscopy the size of the eggndashAuNCs was well-dispersed and
the average diameter of ca 545 nm In addition We demonstrated that the
metallophilic bond between Au+ and Hg
2+ would quench the red fluorescence of
eggndashAuNCs leading to develop the as-prepared eggndashAuNCs as the nanoprobe for
Hg2+
ions The limit of detection for Hg2+
ions was 219 M (SN Ratio = 3) The
practicality of the eggndash AuNCs probe was validated for the determination of Hg2+

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
ZnO is a typical group II-VI semiconductor compared with classical photocatalyst titanium
oxide (TiO2) ZnO nanopowders have a similar band gap energy (32 eV) It is very suitable
as photocatalyst materials because of their non-toxic high performance low cost We study
the relationship between the properties of ZnO calcination temperatures and the
concentration of doped impurities In this study The synthesis was accomplished by using
triblock copolymer (F127) as the natural template and zinc nitrate as the precursor undoped
as well as boron-doped ZnO nanopowders were prepared by sol-gel process The
characteristics of ZnO nanopowders was analyzed by X-Ray diffraction (XRD) scanning
electron microscope (SEM) and field emission transmission electron microscopy (TEM) The
effects of boron-doping and calcination temperatures on the structural and photocatalytic
properties of ZnO particles were investigated The X-Ray diffraction results revealed that the
prepared structure of ZnO is wurtzite structure in this study Due to boron-doping the
substitution will lead to the contraction of the lattice and thereby causes the (101) peak to shift
to high angle The scanning electron microscope results revealed that the synthesis of ZnO
particles were easily agglomerated In photocatalytic activity testing the prepared
boron-doped ZnO nanopowders catalysts shown enhanced photocatalytic activity than pure
ZnO under ultraviolet irradiation for AO7 degradation The best degradation for AO7 can
reach 100 within 30 minutes irradiation when the content of boron is at 001 and the

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

摘要 卷積神經網路(convolutional neural network CNN)是由許多的卷積層與池化層串聯最後再 以全連接層方式所構成的神經網路在卷積層卷積運算元是以移動視窗在輸入區域作點對點的乘積加總而這個移動視窗也稱為核濾波器或特徵探測器另一方面池化層 主要是減採樣(subsample)其輸入因此可以大幅減少輸入資料量及
網路參數的運算與更新時間同時也降低過擬合發生的機率常用的池化運算元是以取最大值為主卷積層與池化層的功能使得卷積神經網路具有位置不變與組成性的特性位置不變是因為濾波器是以視窗的方式移動於輸入區域所以任何特定的物件可以被偵測得到另外每一濾波器是構成區域性的低階特徵這些低階特徵再組成高階的特徵以圖像識別為例圖像的原 始輸入是像素藉由相鄰像素組成線條再由多個線
條組成紋理進一步形成特定圖像所以卷積神經網路以低層次表達的基礎經由線性或者非線性組合然後重複這個過程最後得到高層次的表達因此卷積神經網路也常被應用於圖像識別或是機器視覺的領域 關鍵詞卷積神經網路卷積池化

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳
導實驗結果發現添加BN確實有提升的效果添加比例為005wt的銲件明顯的提升約

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands
Keywords spin splitting magnetoresistance heterostructure cyclotron resonance

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and

frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

網路參數的運算與更新時間同時也降低過擬合發生的機率常用的池化運算元是以取最大值為主卷積層與池化層的功能使得卷積神經網路具有位置不變與組成性的特性位置不變是因為濾波器是以視窗的方式移動於輸入區域所以任何特定的物件可以被偵測得到另外每一濾波器是構成區域性的低階特徵這些低階特徵再組成高階的特徵以圖像識別為例圖像的原 始輸入是像素藉由相鄰像素組成線條再由多個線
條組成紋理進一步形成特定圖像所以卷積神經網路以低層次表達的基礎經由線性或者非線性組合然後重複這個過程最後得到高層次的表達因此卷積神經網路也常被應用於圖像識別或是機器視覺的領域 關鍵詞卷積神經網路卷積池化

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Nickel-based superalloy is the major material of turbine engine During its
manufacturing process vacuum brazing technology is usually applied to ensure the excellent
quality of weldments Through adding nanometer-level graphene to the filler metal and
changing the volume of addition this study discusses its influence on the microstructure and
mechanical property of the nickel -based super alloy weldment Inconel 718 The result finds
out that there are continuous inter-metallic compounds gathering in the original weld with
high hardness value However after adding the graphene the metallic compounds become
equally distributed in the weld which means graphene has effect on the homogenization of
weld Besides the hardness value of the weld center has sharply reduced to a level close to
the base metal If the volume of audition reaches 07wt there will be holes forming in the
graphene weld if it is 03wt the maximum shear strength of the graphene weldment will
be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has
effect on narrowing the weld width

frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

摘要 卷積神經網路(convolutional neural network CNN)是由許多的卷積層與池化層串聯最後再 以全連接層方式所構成的神經網路在卷積層卷積運算元是以移動視窗在輸入區域作點對點的乘積加總而這個移動視窗也稱為核濾波器或特徵探測器另一方面池化層 主要是減採樣(subsample)其輸入因此可以大幅減少輸入資料量及
網路參數的運算與更新時間同時也降低過擬合發生的機率常用的池化運算元是以取最大值為主卷積層與池化層的功能使得卷積神經網路具有位置不變與組成性的特性位置不變是因為濾波器是以視窗的方式移動於輸入區域所以任何特定的物件可以被偵測得到另外每一濾波器是構成區域性的低階特徵這些低階特徵再組成高階的特徵以圖像識別為例圖像的原 始輸入是像素藉由相鄰像素組成線條再由多個線
條組成紋理進一步形成特定圖像所以卷積神經網路以低層次表達的基礎經由線性或者非線性組合然後重複這個過程最後得到高層次的表達因此卷積神經網路也常被應用於圖像識別或是機器視覺的領域 關鍵詞卷積神經網路卷積池化

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
We have investigated the electrical property of the carrier spin in a magnetic field with the
Subnikov-de Haas oscillation techniques The effect of quantum confinement is very
remarkable as the carrier in the low dimension of semiconductor heterostructure The
conductivity will be observed as oscillation form with increasing magnetic field due to the
broadening of the Landau level This is a useful tool to determine the effective mass and
carrier concentration of semiconductor The concentration of carrier is determined by the
frequency of oscillation signal It is found that the magnetoresistance expresses an oscillation
beating in a variance of magnetic field It reveals that the subbands will exist in this
semiconductor system The spin splitting will be determined from the energy different of two
subbands

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
Vanishing gradient problem is a serious issue in training neural networks with gradient based
methods In particular this problem makes it really hard to learn and tune the parameters of
the earlier layers in the network This problem becomes worse as the number of layers
increases In this study a greedy layer-wise (ie contrastive divergence) pre-training method
is applied to ensure that the between-layer weights are properly initialized prior to its actual
training In this sense the Restricted Boltzmann Machine (RBM) is used to fulfill this task A
restricted Boltzmann machine is a generative stochastic neural network that can learn a
probability distribution over its set of inputs RBM is a two-layer neural network The two
layers are fully connected to each other and there are no inner connections inside the layers
During training RBM automatically adjusts its weights based on what it perceives Learning
procedure of the RBM consists of several steps of Gibbs sampling and adjusting the weights
to minimize reconstruction error Usually Training is done using the Contrastive Divergence
algorithm After the training is completed the deep belief networks (DBNs) can be formed by
stacking multiple RBMs together and optionally fine-tuning the resulting deep network
with gradient descent and backpropagation

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
The recent explosion of big data size has prompted the development of feature
dimension reduction to facilitate the further data processing and classification In fact
dimension reduction is the pre-processing approach of reducing the number of random
variables under consideration via obtaining a set of principal variables or features Therefore
dimension reduction is not only useful to speed up execution but actually might help with the
final classificationclustering accuracy as well In this study we explore some commonly used
techniques for this issue including filter method and wrapper method and compare their
performances The filter method evaluates feature subsets by their information content using
distance measures correlation measures etc On the other hand the wrapper based techniques
use a machine learning algorithm to find the feature subset with the best performance
Certainly the wrapper method requires more computation costs but results in more accurate
consequences Since the wrapper method relies on learning schemes it can be divided into
supervised and unsupervised strategies The former one includes Fisher linear discriminant
analysis and neural networks while the later one includes principle components analysis
singular value decomposition and Independent components analysis etc The experimental
results illustrate that the wrapper method for feature selection can lead to higher classification
rates

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

Abstract
In pattern recognition or classification task it always requires that input data is
mathematically and computationally convenient to process However real-world data such as
images video and sensor measurement is usually complex redundant and highly variable
Thus it is necessary to discover useful features or representations from raw data
Unfortunately traditional hand-crafted features often involve expensive human labor and rely
on engineering skill and domain expertise This motivates the design of efficient feature
learning techniques to automate and generalize the classification issue Recently deep
learning with its particular structure including the notion of receptive fields via weights
sharing and distortion invariance with pooling operations has been demonstrated to be
effective both at uncovering underlying structure in data and has been successfully applied to
a large variety of problems ranging from image classification to natural language processing
and speech recognition Deep learning algorithms attempt to learn multi-level representations
of data in multiple layers of increasing abstraction embodying a hierarchy of factors that may
explain them In this study we demonstrate how the deep learning algorithm can be applied
for computer vision problems particularly to isolated character recognition and handwriting
recognition

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

摘要 卷積神經網路(convolutional neural network CNN)是由許多的卷積層與池化層串聯最後再 以全連接層方式所構成的神經網路在卷積層卷積運算元是以移動視窗在輸入區域作點對點的乘積加總而這個移動視窗也稱為核濾波器或特徵探測器另一方面池化層 主要是減採樣(subsample)其輸入因此可以大幅減少輸入資料量及
網路參數的運算與更新時間同時也降低過擬合發生的機率常用的池化運算元是以取最大值為主卷積層與池化層的功能使得卷積神經網路具有位置不變與組成性的特性位置不變是因為濾波器是以視窗的方式移動於輸入區域所以任何特定的物件可以被偵測得到另外每一濾波器是構成區域性的低階特徵這些低階特徵再組成高階的特徵以圖像識別為例圖像的原 始輸入是像素藉由相鄰像素組成線條再由多個線
條組成紋理進一步形成特定圖像所以卷積神經網路以低層次表達的基礎經由線性或者非線性組合然後重複這個過程最後得到高層次的表達因此卷積神經網路也常被應用於圖像識別或是機器視覺的領域 關鍵詞卷積神經網路卷積池化

Abstract
The convolutional neural network (CNN) usually consists of a number of convolutional and
pooling layers and then followed by one or more fully connected layers as in a standard
multilayer neural network The operation of convolution is by thinking of it as a sliding
window function applied to its input The sliding window is called a kernel filter or feature
detector On the other hand pooling layers subsample their input Its function is to
progressively reduce the spatial size of the representation to reduce the amount of parameters
and computation in the network and hence to also control overfitting The most common
way to do pooling it to apply a max operation to the result of each filter The operations of
convolution and pooling lead to two important aspects of the CNN ie location invariance
and compositionality The property of location invariance comes from the fact that the filter
is sliding over the whole image Any specific object can be possibly identified Furthermore
each filter composes a local patch of lower -level features into higher-level representation It
makes intuitive sense that the CNN can build edges from pixels shapes from edges and
more complex objects from shapes These distinct features make CNNs so powerful in the
field of image classification

Abstract
In this work a deposition method was developed to prepare gallium nitride (GaN)
nanowires with different diameters by vapor-liquid-solid mechanism GaN nanowires have
been successfully synthesized on the GaNSapphire substrates deposited a gold film In this
work a gold film of 5~15 nm in thickness was deposited onto the surfaces of GaNSapphire
substrate as the catalyst metal for nanowires growth The synthesis of GaN nanowires was
carried out in a high-temperature tube furnace Argon with a flow rate of 100 sccm was
introduced into the tube The synthesis temperature and pressure were about 1000ordmC and 1
atm respectively This synthesis method is simple and controllable it may be useful in
large-scale synthesis of various nanowires The GaN nanowires were characterized by X-ray
diffraction (XRD) and field-emission scanning electron microscopy (FESEM) Analysis of a
number of the nanowires shows that the diameters of nanowires vary from 148 to 180 nm and
the lengths are up to several micrometers indicating a high aspect ratio There appears to be
strong correlation between the thickness of Au film and the diameter of the nanowires The
samples were examined with X-ray diffraction meter all of the diffraction peaks were
indexed and identified as the hexagonal wurtzite structure

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82

technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing

Nickel-based superalloy is the major material of turbine engine During its manufacturing process vacuum brazing
technology is usually applied to ensure the excellent quality of weldments Through adding nano-graphene to the filler metal
and changing the volume of addition this study discusses its influence on the microstructures and mechanical properties of
Inconel 718 weldment The result finds out that there are continuous intermetallic compounds gathering in the original brazed
seam with high hardness value However after adding the graphene the intermetallic compounds become equally distributed
in the brazed seam which means graphene has effect on the homogenization of brazed seam Besides the hardness value of
the brazed seam center has sharply reduced to a level close to the base metal If the volume of addition reaches 07 wt
there will be holes forming in the graphene brazed seam if it is 03wt the maximum shear strength of the graphene
weldment will be about 3908 MPa increasing by nearly 3 Moreover adding a little graphene also has effect on narrowing
the width of brazed seam

摘要
本研究係將奈米級氮化硼(BN)添加在BNi-2填料金屬來改善316L不銹鋼之真空硬銲
銲件的熱傳導性質實驗結果顯示隨著BN的比例增加銲件的熱傳導速率也會隨著
增加然而當達到1wt以上時BN會在銲縫中心大量的聚集而導致浸蝕時大量的被
剝落造成銲縫出現明顯的孔洞此種大量堆聚的現象會使銲件無法順利完全被接合
而且添加BN亦會誘發銲縫中心之金屬間化合物析出且堆積量增加使形成連續帶狀
組織此時銲縫中心的硬度大幅提升造成和母材間的硬度差異擴大剪切測試時會
在該處形成微裂縫直到破斷當添加BN比例增加時剪切強度有降低的趨勢熱傳
導實驗結果發現添加BN確實有提升的效果添加比例為005wt的銲件明顯的提升約

Abstract
The study adds the nanoscale BN to the filler metal of BNi-2 to improve the thermal
conduction property of vacuum brazing welding compositions of 316L stainless steel The
experimental result shows that With the increase of BN ratio the thermal conductive rate of
welding compositions will increase However as it is over 1wt BN aggregates abundantly
in the center of weld and that causes a large number of peelings as etching As a result
apparent holes appear in the weld The phenomenon of mass aggregation causes the welding
compositions fail to be jointed completely Furthermore the addition of BN can induce the
precipitation of intermetallic compounds(IMC) which are in the center of weld and increase
the packing quantity forming continuous banded textures By this time the hardness in the
center of the weld is increased sharply This enlarges the hardness difference between the
weld and the base metal As the shearing test is conducted the microcracks are formed on the
position until break down When the ratio of addition of BN is increased the shearing
strength is inclined to depress The experimental result about thermal conduction show that
the addition of BN can promote the property indeed and the property of welding compositions
of which addition ratio is 005wt is almost promoted by 82
