The Assembly Line Balancing Problem (ALBP) is to determine the optimal allocation of assembly operations to a set of workstations, with respect to precedence constraints. This paper proposes a multi-objective optimization to solve the ALBP using a Genetic Algorithm (GA) approach. The aim is to minimize, besides the number of workstations, two aspects, very important from an economic point of vi...

Increased speed of workstations and networks have made interactive multimedia communications between workstations across packet-switched networks possible. Transmission of real-time multimedia data over such networks has its limitations and problems. The basic problem pertaining to transmission of audio is synchronization whereas video coding is the main problem for video transmission. ALF and ...

We have developed, implemented and validated a set of flexible and efficient iterative image reconstruction (IIR) and processing methods for clinical positron emission tomography (PET) static or dynamic studies. IIR techniques are shown to produce images of better contrast and signal-to-noise ratio than the conventional filtered back-projection (FBP). Their high computational cost has been a si...

This paper describes ongoing work toward a remote robotics research site which allows repeatable remote experimentation on multiple mobile robots. Our system consists of ten small mobile robots hosting onboard Unix workstations. The robots provide facilities for sensing and moving obstacles, inter-robot positioning and communications, and user input. The Unix workstations allow the user to cont...

This paper summarizes the results of a series of performance tests carried out as part of an evaluation of di erent graphics workstations. The graphics performance was determined by Viewperf 5.1. In addition, we present some results of a relatively simple graphics benchmark, which measures the raw performance with regard to Gouraud-shading. In order to get a good estimation of the processing po...

We present an object-oriented approach to distribute simulation data (like e.g., geometrical information, meshing information, distributed quantities) used for the simulation of semiconductor fabrication processes such as Monte-Carlo ion implantation [1], etching [2, 3), diffusion [4], and oxidation [5] on a heterogenous cluster of workstations. The approach is based on a finite oct-tree where ...

The MYSEA project has produced an innovative architecture and corrresponding engineering prototype consisting of trusted security services and integrated operating system mechanisms for the protection of distributed multi-domain computing environments from malicious code and other attacks. These security services and mechanisms extend and interoperate with existing workstations, applications an...

We present a new approach for the management and enactment of deployment process by a deployment processor ORYA (Open enviRonment to deploY Applications). ORYA aims to integrate technology relevant to process support in deployment systems. The supposed context is a large scale networked organization. The deployment processor called ORYA provides deployment functionalities to distributed, autono...

This paper presents a new method to address the Hybrid Assembly Line Balancing Problem with multiple objectives. The aim is to assign a set of tasks to workstations and select the assembly equipment or resource to perform each of them. The goal is to minimize the total cost of the line by integrating design (congestion, machine real cost...) and operation issues (cycle time, precedence constrai...
