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

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…

A practical HW-aware NAS flow for AI vision applications on embedded heterogeneous SoCs

Implementing efficient Deep Neural Networks (DNNs) for dense-prediction vision applications on embedded heterogeneous SoCs comes with many challenges, such as latency and energy constraints. To tackle them, we propose a novel and practical multi…

Ellipsometry of surface acoustic waves using 3D vibrometry for viscoelastic material characterization by the estimation of complex Lamé coefficients versus the frequency

Surface acoustic waves (SAW) are adequate regarding material characterization because they have low geometric attenuation compared to bulk waves. SAW can be generated easily by normal excitation using contact transducers or power lasers and have…

Acoustics

An innovative method for the objective comparison of the performance of active control devices

In the active control literature, the question of how to objectively and comprehensively compare system performance has received little attention. In most cases, comparisons are only made on a paper-specific application and cannot be extended to new…

Transformateurs piézoélectriques en électronique de puissance

Cet article traite de l’utilisation du transformateur piézoélectrique (TP) dans les convertisseurs électroniques de petite puissance, 0,1 à 10 W. Sa topologie monolithique planaire simple - disques ou barreaux - permet la réalisation de…
