Estimation dense de profondeur combinant approches variationnelles et observateurs asymptotiques

Cet article propose une nouvelle approche pour estimer en temps réel la carte de profondeur instantanée à partir de données inertielles et images fournies par une caméra en mouvement libre dans une scène statique. Une fonction coût invariante par…

Molecular resolution of a dioleoyl-Sn-glycero-phosphocholine lipid bilayer in liquid by phase modulation atomic force microscopy

We present a molecular resolved image of a supported lipid bilayer using atomic force microscopy in liquid conditions. Due to the well-known molecular diffusion processes with velocities of a few nm/s occurring in free-standing membranes, this type…

Exploiting Persymmetry for Low-Rank Space Time Adaptive Processing

Reducing the number of secondary data used to estimate the Covariance Matrix (CM) for Space Time Adaptive Processing (STAP) techniques is still an active research topic. Within this framework, the Low-Rank (LR) structure of the clutter is well-known…

A Non-Heuristic Reduction Method For Graph Cut Optimization

Graph cuts optimization is now well established for their efficiency but remains limited to the minimization of some Markov Random Fields (MRF) over a small number of variables due to the large memory requirement for storing the graphs. An existing…

Efficiency optimization of an electrodynamic MEMS microspeaker

This paper presents the optimization of a novel planar structure of MEMS electrodynamics microspeaker. The mobile part of the device is a microstructured silicon membrane suspended by a whole set of silicon springs. Its actuation principle relies on…

An analysis of Mn-Zn ferrite microstructure by impedance spectroscopy, scanning transmission electron microscopy and energy dispersion spectrometry characterizations

AC (alternative current) resistivity measurement results on Mn-Zn sintered ferrite were analyzed in the 0.1-500 MHz range. From electrical point of view, the material could be represented by an equivalent circuit of parallel resistance-capacitance…

Expériences de recherche en éco-conception dans le domaine du Génie Electrique (Research experiences in ecodesign in the field of Electrical Engineering)

Ce papier propose un bilan de travaux de recherche dans le domaine de l'éco-dimensionnement des convertisseurs d'énergie électrique. Les critères considérés sont réduits à deux : l'énergie primaire consommée sur l'ensemble due cycle de vie et la…
