Acoustics

Design of Autonomous Miniaturized Spherical Acoustic Sensor for Complexe Media Characterization

In this work, a spherical device (1 cm in diameter) composed of two assembled hemispherical shells integrating both the active element (piezoelectric ring) and the integrated electronics dedicated to coding, control and analysis was developed as an…

Analytical iron loss model for the optimization of magnetic gear

This article deals with analytical models dedicated to iron losses in yokes and pole pieces of a magnetic gear with a concentric structure. The magnetic field distribution is determined in yokes by solving both Poisson's and Laplace's equations,…

New Electro-Thermal Model for a Multichip Power Module Used in a Motor Drive

In this paper, we develop an analytical electro-thermal model for a power module with multiple heat sources. This model is applied on a motor drive power converter mounted on its air-cooled heatsink. It offers fast calculations of the junction…

First vs second order magnetocaloric material for thermomagnetic energy conversion

The supply of waste heat represents a huge and freely available amount of energy that make it a key target for energy conversion technologies, notwithstanding the small thermodynamic efficiency to be expected because of the limited working…

On lower bounds for non-standard deterministic estimation

We consider deterministic parameter estimation and the situation where the probability density function (p.d.f.) parameterized by unknown deterministic parameters results from the marginalization of a joint p.d.f. depending on random variables as…

Impact of Model Accuracy in Design by Optimization Process

This paper investigates the effect of model inaccuracies on the results of a design by optimization process applied to a SiC switching cell. The technologies used for this DC-DC converter and the requirements are briefly described, as well as the…
