Magnetoelectric effect in layered ferrite/PZT composites. Study of the demagnetizing effect on the magnetoelectric behavior

We report the use of high magnetomechanical coupling ferrites in magnetoelectric (ME) layered composites. Bilayer samples combining (Ni 0.973 Co 0.027) 1-x Zn x Fe 2 O 4 ferrites (x=0-0.5) synthetized by non conventional reactive Spark Plasma…

Efficient Variational Bayesian Approximation Method Based on Subspace optimization

Variational Bayesian approximations have been widely used in fully Bayesian inference for approx- imating an intractable posterior distribution by a separable one. Nevertheless, the classical variational Bayesian approximation (VBA) method suffers…

L0-Optimization for Channel and DOA Sparse Estimation

This paper is devoted to two classical sparse problems in array processing: Channel estimation and DOA estimation. It is shown after some background and some recent results in l0 optimization how this latter can be used, at the same computational…

Interface Circuit for Vibration Energy Harvesting with Adjustable Bias Voltage

This paper presents a new interface circuit for electrostatic vibration energy harvesting with adjustable bias voltage. An electronic switch is used to modify the circuit configuration so that the harvested energy increases the voltage across a…

Stochastic optimization of an Electric Vehicle Fleet Charging with Uncertain Photovoltaic Production

Simultaneous development of photovoltaic generation and electric vehicles strengthens the solicitations on the electric power system. This paper investigates the possible synergy between these players to jointly improve the production predictability…

Surface crack reconstruction from eddy current images using a direct semi-analytic model

A method relying on a direct semi-analytic model is proposed for reconstructing cracks from eddy current images. We consider systems featuring a uniform excitation flow which can be modelled by means of fictitious current sources distributed in the…
