Dynamic slack reclamation strategy for multiprocessor systems

Imen Mhedhbi, Rabie Ben Atitallah, Abderrazak Jemai

Emerging trends in applications with the requirement of considerable computational performance and decreasing time-to-market have urged the need of multiprocessor systems. With the increase in number of processor there is an increased demand to efficiently control the energy and power budget of…

Iterative semi-continuous relaxation heuristics for the multiple-choice multidimensional knapsack problem

Igor Crevits, Saïd Hanafi, Raïd Mansi, Christophe Wilbaut

Recently several hybrid methods combining exact algorithms and heuristics have been proposed for solving hard combinatorial optimization problems. In this paper, we propose new iterative relaxation-based heuristics for the 0-1 Mixed Integer Programming problem (0-1 MIP), which generate a sequence…

Diagnosis of human operator behaviour in case of train driving: interest of facial recognition

Cyril Legrand, Philippe Richard, Vincent Benard, Frédéric Vanderhaegen, Patrice Caulier

This paper shows a state-of-the-art of facial recognition with reliable algorithms more particularly with Viola and Jones contributions based on the use of Haar-like features suited to temporal constraints of rail drive. Estimations of eyes and mouth positions are provided in relation to face. The…

Simulation de perception humaine limitée : étude de l'influence d'un paramètre de seuil

Utku Görkem Ketenci, Emmanuelle Grislin-Le Strugeon, Roland Bremond, Jean Michel Auberlet

Les Systèmes Multi-Agents constituent désormais une des approches fréquemment utilisées dans un objectif de modélisation et de simulation de trafic routier. Des progrès restent toutefois à accomplir en vue d'améliorer le réalisme des comportements humains simulés, dont le comportement des…

A driver ego-centered environment representation in traffic behavioral simulation

Feirouz Ksontini, Stéphane Espie, Zahia Guessoum, René Mandiau

We present a multi-agent traffic simulation to improve the validity of traffic simulations in urban and suburban fields, with a better consideration of the driving context and driver behavior in terms of anticipation of positioning on the lanes and occupation of space. The demonstration intends to…

Abstract Clock-Based Design of a JPEG Encoder

Adolf Abdallah, Abdoulaye Gamatié, Rabie Ben Atitallah, Jean-Luc Dekeyser

This paper presents the design and analysis of multimedia applications such as the JPEG encoder on multiprocessor architectures. Abstract clocks are considered to deal with the correctness of system behaviors and to find the most suitable execution platform configurations regarding performance and…

Biocompatibility of the Electrical Discharge Machining Process on Titanium Surfaces

Maxence Bigerelle, Karine Anselme, Sylvain Giljean

Pure titanium samples were obtained using electrical discharge machining (EDM) on a spark erosion machine. Twenty-two titanium samples were obtained exhibiting a wide range of arithmetic roughness (Ra) varying from 1 to more than 20.9 µm. The surfaces present an isotropic structure formed by…

The undirected m-Capacitated Peripatetic Salesman Problem

Éric Duchenne, Gilbert Laporte, Frédéric Semet

In the m-Capacitated Peripatetic Salesman Problem (m-CPSP) the aim is to determine m Hamiltonian cycles of minimal total cost on a graph, such that all the edges are traversed less than the value of their capacity. This article introduces three formulations for the m-CPSP. Two branch-and-cut…

Hybrid Bond Graphs for diagnosis of three cells converter

Milka Uzunova, B. Ould Bouamama, Mohamed Djemai

Bond Graph as a unified and multidisciplinary tool, stay very interesting regarding the interaction between different continuous modes. These industrial systems, having more than one continuous state, need hybrid tehniques for their model based diagnosis. Traditional Bond Graph algorithms for…
