We consider the problem of determining the shape of a 2d object from measurements of the electromagnetic far-field it scattered. We develop couplings by considering...

In this PhD thesis I propose coprocessors architectures for high performance computations of asymmetric primitives like RSA, Elliptic Curves and Pairing. Coprocessors...

This thesis aims at studying coupling techniques between Discontinuous Galerkin (DG) and finite difference (FD) schemes in a non-structured / Cartesian hybrid-mesh...

To design a system in power electronics, for instance a converter or an EMC filter, the problems of electromagnetic compatibility are taken into account during the...

Les installations des industries hautes températures (i.e. sidérurgie, incinération...) sont soumises à des conditions d'exploitation sévères. Ces structures...

Ce papier porte sur les méthodes de caractérisation des téléphones mobiles près de la tête. Le but est d'élaborer des méthodes non-invasives pour la dosimétrie de...

On définit ici la "mobilité énergétique" : elle relie la puissance active injectée sur une bande de fréquences en un point d'une structure au niveau carré de la...

Diverses techniques de modélisation sont utilisées en synthèse d'images et en CAO (conception assistée par ordinateur) pour produire des images réalistes et analyser...

Proton exchange membrane fuel cells (PEMFC) make it possible to convert efficiently chemical energy into electricity. For this, hydrogen is oxidized at one of the...

The thesis focuses on the proposed optimization methods (metaheuristics and mathematical models) and their coupling with a simulation model to solve problems of...

Rapport interne.

This work takes place within the general framework of the study of the oscillators coupling. Two aspects are approached which respectively concern the coupling by...

The work presented in this manuscript focuses on the different possibilities leading to the optimization of the signal of localized surface plasmon resonance (LSPR)...

Outdoor sound prediction is both a societal stake and a scientific issue. Thus this paper deals with numerical simulations of micrometeorological (temperature and...

The evolution that principally characterises the microelectronics sector is the reduction of integrated circuits dimensions. Semiconductors industry has not stopped to...

National audience

Since the creation of internal combustion engines, research on gasoline and diesel engines were developed independently. To reduce the time and cost of developing an...

In this PhD thesis, we consider two computational models that address problems that arise when processing massive data sets. The first model is the Data Streaming...
