3D Finite Element Modeling of an Eddy Current Imager

The eddy current (EC) imager appears to be a good alter- native to conventional EC sensors for the non-destructive evaluation of metallic structures, since it provides high speed and high resolution EC images obtained in a large inspection area. In…

Commande mixte $H_2/H_\infty$ : une approche par la stratégie de Stackelberg

La commande mixte $H_2/H_\infty$ consiste à déterminer une commande minimisant la norme $H_2$ d'un système tout en respectant une contrainte sous optimale sur une norme $H_\infty$. Il s'agit d'un domaine de recherche encore largement ouvert, malgré…

AN ACTIVE CHAOTIC MICROMIXER INTEGRATING THERMAL ACTUATION ASSOCIATING PDMS AND SILICON MICROTECHNOLOGY

Due to scaling laws, in microfluidic, flows are laminar. Consequently, mixing between two liquids is mainly obtained by natural diffusion which may take a long time or equivalently requires centimetre length channels. To reduce time and length for…

The Bayesian ABEL Bound on the Mean Square Error

This paper deals with lower bound on the Mean Square Error (MSE). In the Bayesian framework, we present a new bound which is derived from a constrained optimization problem. This bound is found to be tighter than the Bayesian Bhattacharyya bound,…

Evaluation de technologies de substrats céramiques sous des cyclages en température de forte amplitude

Cette étude cherche à évaluer le comportement de substrats céramiques, utilisés pour la réalisation de modules de puissance, pour des applications aéronautiques, à haute température, et sous des cycles de température de forte amplitude. L'article…

Material chemistry

Distance-dependent fluorescence quenching on gold nanoparticles ensheathed with layer-by-layer assembled polyelectrolytes.

We report on the preparation, characterization, and photophysical study of new fluorescent core/shell nanoparticles fabricated by electrostatic layer-by-layer assembly. On the basis of gold cores with a diameter of 13 nm, these nanocolloids possess…

Commande d'un micro cogénérateur Stirling

This paper introduces a Stirling micro-cogeneration system that connects a "double-effect" Stirling engine with a linear induction generator. The connection is done via the engine's piston that serves also as the secondary (rotor) of the generator…
