AC Current Sensor Based on Magnetoelectric Composites Transducers: Resonance Damping, Current Dynamic and Electric Field Disturbances

In this paper, a current sensor based on a magnetoelectric (ME) composite realized by electrodeposition is presented. This ME sample is inserted in the gap of a toric flux concentrator associated with permanent magnets. The current dynamic and the…

Near complete laser-induced modulation of the ferromagnetic-antiferromagnetic phase fraction in FeRh films

With its huge entropy change and a strong interplay between magnetic order, structural and electrical properties, the first-order antiferromagnetic/ferromagnetic phase transition is a paradigmatic example of the multicaloric effect. The unraveling…

Looking for Equivalence between Maximum Likelihood and Sparse DOA Estimators

Sparse Direction-of-Arrival estimators depend on the regularization parameter λwhich is often empirically tuned. In this work, conducted under the vectorized covariance matrix model, we are looking for theoretical equivalence between the Maximum…

Whitening Effects for ML-DoA Estimation using a Sparse Representation of Array Covariance (poster)

Maximum Likelihood (ML) Direction-of-Arrival (DoA) estimation on the Vectorized Covariance Matrix Model (VCMM) exhibits enhanced performance in severe conditions compared to standard methods. Indeed, it benefits from the vectorized covariance matrix…

An efficient and compact supply for electroactive polymers

New trends in electroactive-polymers (EAP) based devices for soft actuators and for electrocaloric cooling revive studies on compact, efficient, reversible and low power supply. High electrode resistance, high voltage and small capacitance of EAPs…

Quantifying nucleation in flow by video-FLIM

During a precipitation experiment in microfluidics, crystals appear in the flow. Using a molecule that turns fluorescent in the solid phase, these crystals can be counted, measured and their polymorph identified. From this collection of data, the…

Physics-informed Markov chains for remaining useful life prediction of wire bonds in power electronic modules

This paper presents a new approach to estimate the remaining useful life of a power electronic module where failure is caused by degradation in the wire bonds. The novelty of this work is that estimation is given for each loading cycle as opposed to…
