Une version récursive de RCOMET pour l'estimation robuste de matrices de forme à structure convexe

Ce papier porte sur l'estimation robuste de matrices de forme (covariance normalisée) structurées. Dans un contexte d'estimation robuste, nous introduisons un estimateur robuste et récursif de matrice de forme basé sur l'estimateur de Tyler. Nous…

Scalar Magnetic Potential Interpolation for Non-Conformal Meshing in Mesh-Based Generated Reluctance Networks

The aim of this paper is to assess the efficacy of non-conformal meshing in mesh-based generated reluctance network modeling. A representative semi-numerical example is introduced to demonstrate the possibilities and accuracy offered by a non…

Modelling and Optimal Sizing of Photovoltaic Water Pumping Systems – Sensitivity Analysis

Recently we have developed a model of photovoltaic water pumping systems (PVWPS) for domestic water access in poor rural areas. In this article, we perform a sensitivity analysis over the 14 parameters of this model. We study how the variation of…

Development of a Hybrid Analytical Model for a Fast Computation of Magnetic Losses and Optimization of Coaxial Magnetic Gears

This article focuses on a 2D analytical model for a fast computation of magnetic losses due to eddy currents in the permanent magnets as well as iron losses in the ferromagnetic parts within coaxial magnetic gears. The magnetic field distribution is…

Asymptotic Performance of Complex M-estimators for Multivariate Location and Scatter Estimation

The joint estimation of means and scatter matrices is often a core problem in multivariate analysis. In order to overcome robustness issues, such as outliers from Gaussian assumption, M-estimators are now preferred to the traditional sample mean and…

Constant ΔTj Power Cycling Strategy in DC Mode for Top-Metal and Bond-Wire Contacts Degradation Investigations

The study of the impact of junction temperature swings ("Tj) on degradation mechanisms during power cycling tests (PCTs) requires both a control of the applied thermal stress and a separation of degradation modes. The first requirement can be…

A new non-isolated low power inductorless piezoelectric DC-DC converter

A new non-isolated low-power inductorless piezoelectric resonant converter is presented. The piezoelectric material is used as an energy storage element like an inductance in a classical Buck-Boost power electronic converter. As opposed to most…
