Identification de régimes de fonctionnement de piles à combustible par reconnaissance de formes à partir d'enveloppes et de fréquences instantanées issues du signal de la tension

Le travail réalisé vise à diagnostiquer des piles à combustible avec une instrumentation et des temps de calculs réduits. L'article décrit un outil de diagnostic non-intrusif, basé sur la seule mesure de la tension du stack et ne nécessitant pas d…

Prédiction de la dynamique d'un convertisseur DC-DC piézoélectrique

Nous proposons une méthode de calcul de la fréquence de fonctionnement d'un convertisseur élévateur DC-DC à base de résonateur piézoélectrique. En outre, nous présentons un modèle électromécanique équivalent du convertisseur en régime établi. Nous…

L0-Sparse DOA Estimation of Close Sources with Modeling Errors

In the field of array processing, Direction-Of-Arrival (DOA) estimation of close sources in the presence of modeling errors is a challenging problem. Indeed, the degradation of high-resolution methods on such scenario is well known and documented in…

Domain structure and energy losses up to 10 kHz in grain-oriented Fe-Si sheets

We investigate in theory and experiment the frequency dependence of magnetic losses in Grain-Oriented 0.29 mm thick high-permeability steel sheets up to 10 kHz. Such unusually broad frequency range, while responding to increasing trends towards high…

Fabrication et caractérisation de puces microfluidiques mimant la microarchitecture du foie, vers le « foie sur puce »

Currently, a high number of drug candidates fail to obtain their marketing authorization or are withdrawn afterwards. This is mostly due to their side effects on the liver, which is the main organ responsible for drug metabolism, that have not been…
