Towards Explainable AI for Channel Estimation in Wireless Communications

Abdul Karim Gizzini, Yahia Medjahdi, Ali Ghandour, Laurent Clavier

Research into 6G networks has been initiated to support a variety of critical artificial intelligence (AI) assisted applications such as autonomous driving. In such applications, AI-based decisions should be performed in a real-time manner. These decisions include resource allocation, localization...

Real-time, chirped-pulse heterodyne detection at room-temperature with 100GHz 3dB-bandwidth mid-infrared quantum-well photodetectors

Quyang Lin, Michael Hakl, Sylvie Lepilliet, Hua Li, Jean-Francois Lampin, Emilien Peytavit, Stefano Barbieri

Thanks to intrinsically short electronic relaxation on the ps time scale, III-V semiconductor unipolar devices are ideal candidates for ultrahigh-speed operation at mid-infrared frequencies. In this work, antenna-coupled, GaAs-based multi quantum-well photodetectors operating in the 10-11`m range...

Interaction of ultrasonic waves with frictional defects in the context of nondestructive testing of materials, Interaction des ondes ultrasonores avec les défauts de frottement dans le contexte du contrôle non destructif des matériaux, Interactie van ultrasone golven met wrijvingsdefecten in de context van niet-destructief materiaalonderzoek

Ravi Verma

This thesis concerns theoretical concepts, models, and experiments for elastic wave propagation and vibrations in solids containing internal contacts (cracks, delaminations, etc.) having frictional nature. The study is oriented to nondestructive testing and therefore focuses on the case where the..., Cette thèse porte sur les concepts théoriques, les modèles et les expériences concernant la propagation des ondes élastiques et les vibrations dans les solides contenant des contacts internes (fissures, délaminations, etc.) ayant une nature frictionnelle.Une partie essentielle du travail est liée...

Comparative study of electrical investigation for temperature measurement in AlGaN/GaN HEMT

Fahmida Sharmin Jui, Sabrina Alam, Anwar Jarndal, Christophe Gaquiere, Mohammad Alim

The modeling of self-heating in GaN-based devices is presented in this paper. A setup for DC I–V and short pulse I–V was used to characterize the device. This paper used four different methods to estimate self-heating, thermal resistance, and channel temperature in a GaN-based high electron...

Andrea Cannizzo

Micro-instability and multi-stability phenomena play a key role in various mechanical and physical systems, both artificial and biological. As such, their understanding is addressed in a wide field of studies, with many practical and theoretical applications. The modeling of the temperature effect..., Les phénomènes de micro-instabilité et de multi-stabilité jouent un rôle clé dans divers systèmes mécaniques et physiques, tant artificiels que biologiques. Leur compréhension fait donc l'objet d'un vaste champ d'études, avec de nombreuses applications pratiques et théoriques. La...

Machine Learning Applications in Medical Diagnosis, case study bone metastasis, Application de Machine Learning dans le domaine de diagnostic médical, cas d'utilisation : métastases osseuses

Marwa Afnouch

Metastases are a group of abnormal cells that develop outside the original organ bound aries and spread to other organs. In particular, bone metastases originate in one organ of the body, such as the breast, lung, or prostate, and spread to the bone. Although this disease was discovered more than a..., Les métastases sont un groupe de cellules anormales qui se développe en dehors des limites de l’organe d’origine et se propagent à d’autres organes. En particulier, les métastases osseuses proviennent d’un organe du corps, tel que le sein, le poumon ou la prostate, et se propagent à l’os. Bien que...
