We have developed a new Synthetic Aperture Radar (SAR) algorithm based on physical models for the detection of a Man-Made Target (MMT) embedded in strong clutter (trunks in a forest). The physical models for the MMT and the clutter are represented…

Réflectométrie fréquentielle (FDR) appliquée à l'évaluation non destructive des conduits de précontrainte extérieure, perspective pour la mesure de la teneur en eau du béton

This paper presents an electromagnetic method of diagnosis based on frequency domain reflectometry (FDR) associated with an inversion algorithm developed by INRIA, ISTLTM (Inverse Scattering for Transmission Lines). ISTLTM allows estimating the…

Spark plasma sintering of Mn–Al–C hard magnets

Structural and magnetic characterization of isotropic Mn-Al-C bulk samples obtained by spark plasma sintering (SPS) is reported. This technique, to our knowledge, has not been used for preparation of Mn-Al-based permanent magnets yet. Transformation…

Micro-Raman spectroscopy for stress analysis in high power silicon devices

Micron-scale characterization of mechanical stress is essential for physic failure studies in power devices. We report the use of Raman spectroscopy to measure mechanical stress in silicon power devices with spatial resolutions down to 500 nm. l…

Fuel Cell System Control under Converter Losses with Experimental Results

The energy management issue of a hydrogen fuel cell (FC) with ultracapacitors (UCs) for applications with high instantaneous dynamic power is considered. Singular perturbation approach is employed for the control of two converters and converter…

A measure-theoretic variational Bayesian algorithm for large dimensional problems

In this paper we provide an algorithm allowing to solve the variational Bayesian issue as a functional optimization problem. The main contribution of this paper is to transpose a classical iterative algorithm of optimization in the metric space of…
