Electric power

PWM interface for piezoelectric energy harvesting

In this study, a wideband electric interface based on pulse width modulation (PWM) for piezoelectric energy harvester is investigated. The switching interfaces are used to increase the output power of energy harvesting devices for wide frequency…

A gametheoretic approach for non-uniform pole shifting and pole homothety

This paper investigates the problems of non-uniform pole shifting or pole homothety in multivariable linear systems by using a gametheoretic approach and more specifically a particular Nash strategy with an open-loop information structure for a game…

Estimating hyperparameters and instrument parameters in regularized inversion. Illustration for SPIRE/Herschel map making.

We describe regularized methods for image reconstruction and focus on the question of hyperparameter and instrument parameter estimation, i.e. unsupervised and myopic problems. We developed a Bayesian framework that is based on the \post density for…

Pulsed eddy current imaging device for non destructive evaluation applications

n this paper, an original pulsed eddy current (EC) imaging system dedicated to the enhanced non-destructive evaluation (NDE) of large metallic parts is presented. The system aims to combine the advantages of the pulsed eddy current (PEC) sensors…

On the Angular Resolution Limit for Array Processing in the Presence of Modeling Errors

In this work, we study the impact of modeling errors on the angular resolution limit (ARL) for two closely spaced sources in the context of array processing. Particularly, we follow two methods based on the well-known Lee and Smith's criteria using…

Model-based Optical Flow For Large Displacements and Homogeneous Regions

Monocular motion analysis for advanced driver assistance systems (ADAS) is a very active research topic. However, two constraints limit the implementation of existent techniques in autonomous vehicles: poorly textured regions and large displacements…
