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...

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...

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...

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...

Numerical and Experimental Evaluation of the Critically Refracted Longitudinal Waves (LCR) Beam Profile Generated by a Transducer

W. Djerir, T. Boutkedjirt, Mohamed Ourak, R. Halimi, A. Rezzoug, F. Rekbi, A. Allag

Due to its advantageous properties, the critically refracted longitudinal waves (LCR) are used in various fields of nondestructive evaluation, especially for residual stress measurements. However, although many researches use these waves, the characteristics of the LCR beams are not completely...
