Assembly plays an important role in any production system as it constitutes a significant portion of the lead time and cost of a product. Virtual computer-integrated manufacturing (VCIM) system is a modern production system being conceptually developed to extend the application of traditional computer-integrated manufacturing (CIM) system to global level. Assembly scheduling in VCIM systems is ...

since the analysis of complex services systems by using mathematical modeling techniques, with considering the random patterns prevailing in them, is so difficult or probably impossible, improvement guidelines are often followed based on the experts' experiences using qualitative methods. in the present paper, by employing a discrete event computer simulation methodology, criminal trial sy...

The paper presents selected mathematical methods of digital signal and image processing based upon the use of wavelet transform and signal decomposition with applications in system identification, analysis and modelling. The main part of the paper is devoted to signal de-noising using hard and soft thresholding and to the recovery of degraded parts of signals and images. The wavelet transform a...

A real-time distributed image processing system requires data transfer, synchronization and error recovery. However, it is di cult for a programmer to describe these mechanisms. To solve this problem, we are developing a programming tool for real-time image processing on a distributed system. Using the programming tool, a programmer indicates only data ow between computers and image processing ...

We describe an architecture for nonintrusive failure detection and recovery in a cluster of Internet servers in which nodes mutually monitor their liveness and recover client sessions from failed nodes. The system is based on Backdoors, a novel architectural approach for remote healing of computer systems. Backdoors enables monitoring and recovery/repair of state in a computer system by remote ...

This article presents an initial assistive technology strategy for the rehabilitation and monitoring of elderly patients, focused on lower limb muscle recovery, from a condition low gait stability to recovery without use crutches. The project is in progress, its first module, one, measures flexion extension limbs degrees sends data database analysis by physiotherapist. second module consists de...

This paper covers the development, design and simulation of an automatic real time control system applied in mechanical system of recovery of spur gears. using modern techniques of automatic welding. This automatic system permits to recover the initial geometric contour of the wheel by performing automatic welding runs across each tooth, keeping the mechanical properties intact. The thermal mod...

The objectives of this investigation are the studies on the effect of copper ion on photolytic degradation of ethylenediaminetertraaceticacid (EDTA), the effect of EDTA on electrolytic recovery of copper as well as the introduction of a novel combined photolytic and electrolytic cell system for simultaneous recovery of copper and the degradation of EDTA.In this experimental study, ...
