Design Problems" will demonstrate how university educators can readily integrate real‐world

sustainability principles into the curricula, using coursework learning tools that teach whole systems and

life cycle thinking, energy effectiveness, and materials selections strategies.


Alexandru Patriciu McMaster University

CANADA

Topic:

Parallel Algorithms for Needle Insertions in Soft Tissues using NVIDIA CUDA

Abstract:

Alexandru Patriciu is an Assistant Professor with the Department of Electrical and Computer

Engineering, at McMaster University. His research interests lie in the areas of medical robotics, robotic

assisted deformable objects manipulation, and parallel algorithms for surgical simulations. His keynote

speech will address the issue of designing parallel algorithms for needle insertions in soft tissues using

NVIDIA CUDA parallel architecture.

Rafael Bidarra Delft University of Technology

THE NETHERLANDS

Topic:

How'd You Like Your World Today?

Abstract:

Rafael Bidarra is an Associate Professor of Computer Science at Delft University of Technology, where he

leads the Game Technology Research Lab at the Computer Graphics and Visualization Group. In this

keynote, he will address the current game development challenge of coping with the huge amount of

content in increasingly large game worlds. Much research has been seeking solutions for automating

the content generation process. Procedural methods presently offer very promising results, but are still

far from application in mainstream game development practice due to a number of shortcomings. He

will discuss some of their drawbacks, and how they can be overcome, and introduce declarative

modeling of virtual worlds, an approach aimed at enabling non‐technical professionals to build virtual

worlds as they please. A variety of research results will be illustrated with recent examples.

Yongsheng Ma University of Alberta

CANADA

Topic:

Towards Engineering Assurance via Unified CAD and CAE Feature Interactions

Abstract:

Yongsheng Ma is an Associate Professor at the University of Alberta, where he teaches capstone design

projects, engineering economics and manufacturing processes. His research interests are in feature‐

based product and process modeling, CAD/CAM, and product lifecycle management. Dr. Ma received his

B.Eng. degree from Tsinghua University (Beijing, CHINA), and M.Sc. and Ph.D. degrees from UMIST

(Manchester, UK). From 2000‐2007 he was an Associate Professor at Nanyang Technological University

(SINGAPORE). His CAD'12 keynote presentation is "Towards Engineering Assurance via Unified CAD and

integration between CAD and CAE packages with an object‐oriented multi‐facet representation

approach

Hoda ElMaraghy University of Windsor

CANADA

Topic:

Variety in Design and Manufacturing ‐ Challenges and Opportunities

Abstract:

Professor ElMaraghy holds a Canada Research Chair and is Director of the University of Windsor

Intelligent Manufacturing Systems Centre (IMSC). She is a member of CIRP, and regularly organizes

academic conferences including the International Conference on Changeable, Agile, Reconfigurable and

Virtual Production. Recently, with support from the Ontario government, the IMSC established a new

Innovation Design Studio and Transformable Manufacturing System that will allow users to develop

product ideas from conceptualization to prototyping, design virtual assembly systems, and then build

their product in a real‐world, truly reconfigurable factory in the laboratory. Her keynote is entitled

"Variety in Design and Manufacturing ‐ Challenges and Opportunities".

Michael Heck Visualization Sciences Group

USA

Topic:

An Interface Based API for Mesh Visualization

Abstract:

Michael Heck is the Chief Technology Advisor at Visualization Sciences Group (www.vsg3d.com),

provider of the Open Inventor and MeshViz software development toolkits for 3D visualization in

scientific and engineering applications. His keynote is entitled "An Interface Based API for Mesh

Visualization", and describes the design and implementation of MeshViz XLM. Large meshes and the

associated data are a key challenge in many CAD domains. The API avoids data duplication, and supports

polygonal cells and parametric nonlinear cells. The "Everything is a Mesh" approach maintains a

consistency at all dimensions, with an isosurface being a mesh extracted from a volume mesh, and a

contour line being extracted from a surface mesh, etc.


David McPhail Memex Automation Inc.

Topic:

CNC Connectivity as a Competitive Edge

Abstract:

David McPhail is the CEO of Memex Automation, a growing leader in factory floor connectivity. His

keynote, entitled "CNC Connectivity as a Competitive Edge", will address advancement of machine tool

connectivity to measurement and management of overall factory effectiveness, in which management

has timely access to information on the utilization of each resource. This requires standardized,

bidirectional information pipeline connectivity from the CAD level to the process level.

Dave Edstrom MTConnect Institute

USA

Topic:

MTConnect: How An Open Protocol is Changing Manufacturing

Abstract:

Dave Edstrom is President and Chairman of the Board ‐ MTConnect Institute. His keynote, entitled

"MTConnect: How An Open Protocol is Changing Manufacturing", will describe the fundamental shift

that is happening in manufacturing with productivity that is being sparked by the open, royalty free and

open source protocol MTConnect. This presentation will discuss how small shops and large plants are

selecting MTConnect as the connection protocol between their shop floors and their applications to

improve productivity. MTConnect is not an application, but a protocol that is making it very easy to get

information off manufacturing equipment in an easy to read format as well as making it very easy for

applications to read that data so problems can be found and fixed so productivity can go up. Dave is also

the CEO/CTO for Virtual Photons Electroncs and has been in the computer industry for 33 years,

including 23 years with Sun Microsystems in a variety of leadership positions. He has been working with

AMT ‐ The Association for Manufacturing Technology as the Director for the Office of Strategic

Innovation.

Chair: Allan Spence


10th Annual CAD Conference June 17‐20, 2013 – Bergamo, Italy

It is a pleasure to announce that the 10th anniversary International CAD Conference and Exhibition is

planned to be held in Bergamo, Lombardy Region, Italy, June 17‐20, 2013.

Lombardy Region lies in the north of the

country, sharing a border with

Switzerland. Stretching from the Alps to the

lowlands of the Po Valley, it is home to a wide

range of landscapes, including the breath‐taking

mountain chain, the charm of the great lakes,

such as Garda Lake, Como Lake and Maggiore

Lake.

Beside Milan, the Region includes

historical and industrial cities, such

Bergamo, Brescia and others, where

history, art and culture are

harmoniously combined with

innovation, technology, fashion,

entertainment and a contemporary

outlook.

Contributions from all aspects of CAD are expected including Modeling, Analysis, High‐Performance

Graphics, Data Management, Knowledge Engineering, Collaborative Design, Reverse Engineering, and

Prototyping. Applications can be in Architecture, Bio‐ Medicine, Civil Engineering, Fashion Industry,

Industrial Design, Sustainable Energy Design, etc.
