Sparsity-Based Estimation Bounds With Corrupted Measurements

In typical Compressed Sensing operational contexts, the measurement vector y is often partially corrupted. The estimation of a sparse vector acting on the entire support set exhibits very poor estimation performance. It is crucial to estimate set I…

Electrostatically actuated thermal switch device for caloric film

An innovative thermal switch device using a thin metallic film electrostatically actuated by an electrode mainly conceived for caloric cooling is studied. Our study focuses on the characterization of the thermal conductance at the interface for the …

Analytical Solutions to the Problem of the Grain Groove Profile

During the last sixty years, the problem of the formation of grain boundary grooving in polycrystalline thin films, was largely studied, analyzed and commented. The thermal effect on the properties of the grain boundary grooving was first studied by…

New Analytical Model for Real-Time Junction Temperature Estimation of Multichip Power Module Used in a Motor Drive

A new analytical electro-thermal model of a multichip power module is described in this paper. The proposed model is intended to be used during in-service conditions inside a motor drive for remaining useful lifetime calculation, in combination with…

Metamodel-based Markov-Chain-Monte-Carlo parameter inversion applied in eddy current flaw characterization

Flaw characterization in eddy current testing usually requires to solve a nonlinear inverse problem. Due to high computational cost, Markov Chain Monte Carlo (MCMC) methods are hardly employed since often needing many forward evaluations. However,…

Rollover risk prediction of heavy vehicles by reliability index and empirical modelling

This paper focuses on a combination of a reliability-based approach and an empirical modelling approach for rollover risk assessment of heavy vehicles. A reliability-based warning system is developed to alert the driver to a potential rollover…

Ensure an original and safe “fail-to-open” mode in planar and trench power SiC MOSFET devices in extreme short-circuit operation

The purpose of this paper is to present a complete experimentation of the two failure modes in competition that can appear during short-circuit (SC) fault operation of single-chip 1,2kV SiC MOSFETs from different manufacturers including planar and…
