Pillar-type acoustic metasurface

Yabin Jin, Bernard Bonello, Rayisa P. Moiseyenko, Yan Pennec, Olga Boyko, Bahram Djafari-Rouhani

We theoretically investigate acoustic metasurfaces consisting of either a single pillar or a line of identical pillars on a thin plate, and we report on the dependence on the geometrical parameters of both the monopolar compressional and dipolar bending modes. We show that for specific dimensions...

A text-dependent speaker-recognition system

Dany Ishac, Antoine Abche, Elie Karam, Georges Nassar, Dorothée Debavelaere-Callens

In this work, a voice recognition approach is developed and presented. It is a based on acquiring the signal of vocal cords' vibrations of a person using a piezoelectric transducer element attached on a collar wrapped around the neck. The recognition is then based on the vocal cords vibrations...

The influence of the presence of a defect in a structure on the cross-correlation, application to the tubular structure

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

The aim of this paper is to verify experimentally the constant possibility of performing a Structural Health Monitoring (SHM) in a medium by studying the ambient noise present therein. First, we will illustrate the equivalence between the Green's function and the cross-correlation, then we...

Study of the positioning of wireless sensors for communication at 2.4 GHz inside the train

Ulrich Biaou, Sara Iben Jellal, Michael Bocquet, S. Baranowski, Atika Rivenq, Philippe Mariage

The benefits of wireless sensor networks (WSN) offer many possibilities for the management of energy systems, which are actually based on wired systems. The need of new services on-board the train and of cables lengths reduction promote the use of wireless sensor networks in trains. Then,...

Acoustic source localization based on the similarity rate between frequency-time images

Karl Hourany, Youssef Zaatar, Farouk Benmeddour, Emmanuel Moulin, Dorothée Debavelaere-Callens, Jamal Assaad

Many studies in different domains have shown the possibility of extracting information from a medium by exploiting the natural acoustic noise present in such medium. Recently, the promising potential of a passive acoustic technique, based on the correlation of the ambient noise for controlling the...

Thermal conductivity of glassy GeTe4 by first-principles molecular dynamics

Assil Bouzid, Hayat Zaoui, Pier Luca Palla, Guido Ori, Mauro Boero, Carlo Massobrio, Fabrizio Cleri, Évelyne Martin

A transient thermal regime is achieved in glassy GeTe4 by first-principles molecular dynamics following the recently proposed “approach-to-equilibrium” methodology. The temporal and spatial evolution of the temperature do comply with the time-dependent solution of the heat equation. We demonstrate...
