Broadband Dielectric Characterization of Bentonite for Hydromechanical Monitoring

We report a method relying on a dielectric spectroscopy laboratory experimental setup and on a suitable electromagnetic model for the broadband characterization of compacted partly saturated bentonite under controlled boundary conditions. This work…

A subspace approach for shrinkage parameter selection in undersampled configuration for Regularised Tyler Estimators

Regularized Tyler Estimator's (RTE) have raised attention over the past years due to their attractive performance over a wide range of noise distributions and their natural robustness to outliers. Developing adaptive methods for the selection of the…

Dielectric Characterisation of Single Microalgae Cell Using Electrorotation Measurements

This study demonstrates the electrorotation of single microalgae cells captured in the center of a set of planar microelectrodes within a microfluidic device, and compares the rotational speeds of single microalgae cells obtained in experiments and…

Dimensionnement Magneto-Mécanique des Plots Feuilletés d'un Multiplicateur Magnétique pour l'Éolien de Forte Puissance

This article deals with the magneto-mechanical sizing of laminated ferromagnetic pole pieces of a magnetic gear. This ring is subjected to a magnetic field, which generates radial and tangential loads on the pole pieces. To ensure the mechanical…
