Impact de la transformée de Keystone sur la détection de cibles radar

Ait Taleb, Abigael Taylor, Valentine Wasik, Yassin El Hillali

La transformée de Keystone (KT) est une méthode utilisée pour corriger la migration distance des cibles en mouvement sans connaissance a priori de leur vitesse. Cette méthode repose sur une transformation temporelle via l'interpolation de la compression d'impulsions dans le domaine…

A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials

Nesrine Bakalem, Abdelkader Aissat, Samuel Dupont, Faouzi Saidi, Mohamed Houcine Dhaou, Jean Pierre Vilcot

This investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa$_{1-x}$As/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching. Initially, we performed calculations on strain, bandgap…

Modeling Mechanical Micro-instabilities in Biophysics and Materials Science

Andrea Cannizzo, Manon Benedito, Fabio Manca, Stefano Giordano

From biophysics to materials science, mechanical micro-instabilities play a central role in a multitude of materials and structures (adhesion, fracture, friction, phase transformations and so on). Although these systems are very different in length-scale, time-scale and morphology, they are all…
