Scanning microwave microscopy for investigations of mechanical vibrations and mode coupling

Xin Zhou, D. Theron, H. Xu, Christophe Boyaval, Sophie Eliet, Pascal Tilmant

In recent years, scanning probe microscopy has attracted interests for dielectric property characterization at the nanoscale of a wide range of materials due to its capability to measure aF scale capacitances or variations [1]. For this reason, it can be exploited to manipulate nanomechanical…

Extending the Griffith energy criterion on fracture propagation to include thermal effects

Claudia Binetti, Stefano Giordano, Nicola Maria Pugno, Giuseppe Florio, Giuseppe Puglisi

Fracture is an issue that has been faced for as long as there have been man-made structures. Numerous studies have been dedicated to analyzing fracture and crack propagation, with significant contributions from various researchers.The pioneer in this field was Griffith, who, in 1921, laid the…

Deep-Covid-SEV: an Ensemble 2D and 3D CNN-Based Approach for Covid-19 Severity Prediction from 3D CT-SCANS

Fares Bougourzi, Fadi Dornaika, Amir Nakib, Cosimo Distante, Abdelmalik Taleb-Ahmed

Since the advent of Covid-19 in late 2019, medical image analysis with artificial intelligence (AI) has become an important research topic. CT-scan imaging is an important diagnostic tool for this disease. This study is part of the 3rd COV19D competition for Covid-19 Severity Prediction, where we…

Bus network decomposition for fault detection and isolation through power line communication

Abdel Karim Abdel Karim, M. Amine Atoui, Virginie Degardin, Pierre Laly, Vincent Cocquempot

This paper deals with fault detection and isolation (FDI) in complex embedded wired communication networks. The considered faults are soft faults which do not prevent the communication, but may evolve into hard faults, i.e. short or open circuit. A novel FDI method based on power line communication…

Elastic and thermo-elastic characterizations of thin resin films using colored picosecond acoustics and spectroscopic ellipsometry

Arnaud Devos, Fabrice Chevreux, Christophe Licitra, Asma Chargui, Laurent-Luc Chapelon

Colored Picosecond Acoustics (CPA) and Spectroscopic Ellipsometry (SE) are combined to measure elastic and thermoelastic properties of polymer thin-film resins deposited on 300 mm wafers. Film thickness and refractive index are measured using SE. Sound velocity and thickness are measured using CPA…

UTD-Based Ray-Tracing MIMO Channel Modeling for the Next-Generation Communications Within Underground Tunnels

Mohamad Ghaddar, José-María Molina-García-Pardo, Ismail Ben Mabrouk, Martine Lienard, Pierre Degauque

Limited work has previously been conducted into deterministic modeling of the fifth generation (5G) millimeter (mm)-wave wireless communications within geometrically nonuniform tunnels. This study predicts and analyzes broadband multiple–input multiple–output (MIMO) propagation in underground mine…

Reduction of helium permeation in microfabricated cells using aluminosilicate glass substrates and Al2O3 coatings

Clément Carlé, Shervin Keshavarzi, Andrei Mursa, Petri Karvinen, Ravinder Kumar Chutani, Sylwester Bargiel, Samuel Queste, Rémy Vicarini, Philippe Abbé, Moustafa Abdel Hafiz, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

The stability and accuracy of atomic devices can be degraded by the evolution of their cell inner atmosphere. Hence,<br /&gt the undesired entrance or leakage of background or buffer gas, respectively, that can permeate through the cell walls,<br /&gt should be slowed down. In this…

Efficient mitigation of railway induced vibrations using seismic metamaterials

Slimane Ouakka, Abdellatif Gueddida, Yan Pennec, Bahram Djafari-Rouhani, Georges Kouroussis, Olivier Verlinden

AbstractThe fast growth of railway transport pushed by its sustainability requires all railway stakeholders to work together to minimise any possible drawbacks that might slow down this positive trend. Among these, the induced vibrations generated at the wheel–rail interaction during train passage…

Deep learning-based hard spatial attention for driver in-vehicle action monitoring

Imen Jegham, Ihsen Alouani, Anouar Ben Khalifa, Mohamed Ali Mahjoub

Distracted driving is one of the main causes of deaths and injuries in the world. Monitoring driver behaviors through Driver Action Recognition (DAR) contributes significantly to building safer transportation systems. However, in naturalistic driving settings, this task is complex and challenging…

Sensor Sensitivity Based on Exceptional Points Engineered via Synthetic Magnetism

S.R. Mbokop Tchounda, P. Djorwé, S.G. Nana Engo, B. Djafari-Rouhani

An efficient mass sensor based on exceptional points (EPs), engineered under a synthetic magnetism requirement, is proposed. The benchmark system consists of an electromechanical (optomechanical) system where an electric (optical) field is driving two mechanical resonators that are mechanically…
