Self-oscillation and heat management in a LaFeSi based thermomagnetic generator

Harvesting and directly converting the largely untapped and omnipresent lowgrade heat into electricity has huge technological potential for supplying internet of things (IoT) devices, and wireless sensors in smart buildings applications. To this end…

Off-Grid Radar Target Detection with the Normalized Matched Filter: A Monopulse-Based Detection Scheme

In this paper, we tackle the problem of off-grid radar target detection based on the Normalized Matched Filter. State-ofthe-art solutions to this problem include the use of the Generalized Likelihood Ratio test (GLRT), whose implementation can be…

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…

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…
