Dimensionnement d'un filtre hybride de mode commun

This paper proposes the study and the design of a common mode hybrid electromagnetic interference (EMI) hybrid filter (HEF) able to cancel the CM electromagnetic interference noise in a given frequency range. In hybrid EMI filtering, low frequency…

Dimensionnement d'un Filtre CEM Actif de Mode Commun

Ce papier propose une méthodologie de dimensionnement d’un filtre CEM actif (AEF) de mode commun (CM) capable d’atténuer les perturbations électromagnétiques dans une plage de fréquence donnée. L’étude et l’analyse de l’AEF sont basées sur le modèle…

Material characterization by surface wave parameters extraction using 3D vibrometer and ellipsometry

Abstract This work focuses on the monitoring of the 3D propagation of ultrasonic surface waves used in non-destructive testing and evaluation. The ellipticity of the movement related to the Rayleigh wave, specifically the H/V parameter, is studied…

Thermal Reconversion of Oxidised Lead White in Mural Paintings via a Massicot Intermediate

Lead white is the most ancient and common white pigment used in mural paintings. However, it tends to blacken with time due to its oxidation to plattnerite (\b{eta}-PbO2). Chemical treatments were used but they can put the pictorial layers supports…
