The present paper intends to analyze the methods ofefficiency computing for a cache memory from acomputer memory system. After describing theprinciples of a cache memory, the efficiency isintroduced based on the two locality mechanisms: thespace locality and the time locality. The efficiency isstudied as a function of the cache memory capacity,taking into account the influence of severalparameters. The results are very useful in evaluatingthe memory system behavior in different applications.

The paper will present the speed control systemdeveloped at ICPE SAERP SA Bucharest for tractionequipments consisting in more than one drive, as thetwo-motored tramcar, the double-unit metro or thetractor coach for railway are. The system containshierarchical processor controllers for speed andtorque. The main connections between processorunits are serial connections, and the communicationprotocol has special safety tasks. The speedregulators are based on velocity measurements of theaxles and are located at main controllers in order tooperate at low frequency. Each of the motor units isdriven with individual power converters. Inside thepower converter is located a slave processor whichperforms the current regulation based on the localtransducers. The diagnose tasks are both global with

master controller and local by every slave controller,so the central diagnose task can operate the data withhigh resolution. The system allows the addition ofseveral motored units and can be driven from aselectable cabin. Further converter and motorevolution will easily fit inside the system.

Phenomena taking place into an electromagneticshield are complex (absorption, reflection,transmission). They are determined by material/shieldmacroscopic parameters (, , ), its thickness,radiation's frequency and incidence angle. The paper

deals with an original method for visualization andmeasurement of shielding effectiveness. This methodhas the advantage of simplicity and validates for thefirst time theoretical predictions as opposed to TEMcell method based on mathematical isomorphism(infinite plane shield vs. coaxial transmission lines).Even if it is formally accurate, it has not beenexperimentally validated up to present, in the area ofelectrically thick samples, according to numerousworks in the field.

For theoutlet of the dryer, the moisture measurement formoistures from 7% to 29% resulted in a standarddeviation of sd = 0,51%.

EEA 55, nr. 3-4, jul. dec. 2007, p. 77

The profile of required performances for modernfireproofing materials was significantly modified in therecent years. Besides their effective role in the ignitionprocess, the environment considerations play animportant role in all the phases of the product lifetime starting with manufacturing, processing, use andpost-use recycling. Which is why initiatives were takenby both manufacturers, and users.Depending on its features, the fireproofing material(FR) may operate chemically and/or physically(reactive fireproof materials or additives) in the solidphase, liquid or gas. They interfere with ignition duringa particular phase of this process, for example duringheating, decomposition, ignition or flame conduction.The paper tackles the obtaining of fireproofedcomposite materials without halogens, based on

polypropylene and polyamide 6.
