Suivi, détection et caractérisation d’un front de lixiviation par techniques destructives et non destructives

Charles Ciccarone, Bogdan Piwakowski, Frédéric Skoczylas, Jean-Marie Henault

L’objectif du travail présenté est la détection, la caractérisation et le suivi d’un front de lixiviation sur une structure en béton. Pour cela, les conditions de lixiviations in situ ont été reproduites sur des éprouvettes en laboratoire, et la détection du phénomène recherché a été conduite en…

AlGaN channel high electron mobility transistors with regrown ohmic contacts

Idriss Abid, Jash Mehta, Yvon Cordier, Joff Derluyn, Stefan Degroote, Hideto Miyake, F Medjdoub

High power electronics using wide bandgap materials are maturing rapidly, and significantmarket growth is expected in a near future. Ultra wide bandgap materials, which have an even largerbandgap than GaN (3.4 eV), represent an attractive choice of materials to further push the performancelimits of…

Parasitic loop inductances reduction in the PCB layout in GaN-based power converters using S-parameters and EM simulations

Loris Pace, Nadir Idir, Thierry Duquesne, Jean-Claude de Jaeger

Due to the high switching speed of Gallium Nitride (GaN) transistors, parasitic inductances have significant impacts on power losses and electromagnetic interferences (EMI) in GaN-based power converters. Thus, the proper design of high-frequency converters in a simulation tool requires accurate…

Covid-19 recognition using ensemble-cnns in two new chest x-ray databases

Edoardo Vantaggiato, Emanuela Paladini, Fares Bougourzi, Cosimo Distante, Abdenour Hadid, Abdelmalik Taleb-Ahmed

The recognition of COVID-19 infection from X-ray images is an emerging field in the learning and computer vision community. Despite the great efforts that have been made in this field since the appearance of COVID-19 (2019), the field still suffers from two drawbacks. First, the number of available…

Development of micron sized photonic devices based on deep GaN etching

Karim Dogheche, Bandar Alshehri, Gilles Patriache, El Hadj Dogheche

In order to design and development efficient III-nitride based optoelectronic devices, technological processes require a major effort. We propose here a detailed review focussing on the etching procedure as a key step for enabling high date rate performances. In our reported research activity, dry…

Real-Time In-Lab Test of Eigenvalue-Based Spectrum Sensing Using USRP RIO SDR Boards

Hayfa Ben Thameur, Iyad Dayoub

The diversity of prevailing and emerging cognitive radio (CR) applications makes CR an attractive domain to the researchers as well as the industry. The spectrum sensing (SS) is considered as the backbone of any autonomous CR. Thus, in this letter, we go one step further towards industrial…

Experimental evidence for heavy tailed interference in the IoT

Laurent Clavier, Troels Pedersen, Ignacio Rodriguez, Mads Lauridsen, Malcolm Egan

5G and beyond sees an ever increasing density of connected things. As not all devices are coordinated, there are limited opportunities to mitigate interference. As such, it is crucial to characterize the interference in order to understand its impact on coding, waveform and receiver design. While a…
