Selection of regularization parameter in sparse inverse problems for DOA estimation

This article deals with the selection of the regularization parameter of a sparse L0 regularized criterion for DOA (Direction-of-Arrival) estimation. This parameter is generally empirically obtained. In this paper, we establish a theoretical range…

Magnetic shielding of a thin Al/steel/Al composite

Purpose-This paper aims to investigate the efficiency of a laminated composite for shielding applications. The solution has to be efficient not only for the shield against static magnetic fields but also "for low-frequency ones, in order to be well…

Impact of cyclic mechanical compression on the electrical contact resistance between the gas diffusion layer and the bipolar plate of a polymer electrolyte membrane fuel cell

The electrical contact resistance between the Gas Diffusion Layer (GDL) and the BiPolar Plate (BPP) used in Polymer Electrolyte Membrane Fuel cells (PEMFCs) is responsible for a substantial amount of Ohmic losses in the electrical power generator…

Increase of magnetic and magnetoelectric properties in Co/Mn co-doped BiFeO3 multiferroic

Co and Mn co-doped BiFeO3 samples are successfully realized using a stirred hydrothermal route to form BiFe0.9CoxMn0.1-xO3 (for x=0.01, 0.03, 0.05, 0.07 and 0.09) system. Our data show that both the ferroelectric (TC) and antiferromagnetic (TN)…

Encoding the latent posterior of Bayesian Neural Networks for uncertainty quantification

Bayesian Neural Networks (BNNs) have been long considered an ideal, yet unscalable solution for improving the robustness and the predictive uncertainty of deep neural networks. While they could capture more accurately the posterior distribution of…

Experimental design approach for the synthesis of 3D-CoFe2O4 nanoflowers thin films by low-cost process

Three-dimensional CoFe2O4 nanoflowers thin films have been deposited on stainless steel by low-cost chemical bath deposition process. The experimental design methodology has been applied to investigate the effect of the principal experimental…

To stick or not to stick: Predicting particle capture on a surface in a microchannel

Particle adhesion on a surface is a central mechanism in microsystems, from labeled nano/micro-particle adhesion on a functional surface to wall fouling. We show the significant effect of the coupling of both diffusion and inertial hydrodynamics…
