Coupling Helmholtz resonators for sound manipulation

R. Sabat, Gaëtan Lévêque, Yan Pennec, D. Torrent, Bahram Djafari-Rouhani

In this work, we discuss the interaction between Helmholtz resonators, using the finite element method. We show that the coupling between two spheres gives rise to two resonant modes at low frequencies. One is symmetric and corresponds to a mono-polar breathing mode, as currently observed. The…

Ear Recognition Based on Deep Unsupervised Active Learning

Yacine Khaldi, Amir Benzaoui, Abdeldjalil Ouahabi, Sebastien Jacques, Abdelmalik Taleb-Ahmed

Cooperative machine learning has many applications, such as data annotation, where an initial model trained with partially labeled data is used to predict labels for unseen data continuously. Predicted labels with a low confidence value are manually revised to allow the model to be retrained with…

Embedded ICG-based Stroke Volume Measurement System: Comparison of Discrete-Time and Continuous-Time Architectures

Antoine Gautier, Benoit Larras, Olev Märtens, Deepu John, Antoine Frappé

This paper describes the study of an integrated system for the detection of the B-C-X characteristic points of impedance cardiography (ICG) signals, to evaluate the stroke volume of a patient. It compares a discrete-time digital approach and a continuous-time digital architecture, using a level-…

Identification of ultra high frequency acoustic coda waves using deep neural networks

Venu Babu Thati, Nikolay Smagin, Hatem Dahmani, Julien Carlier, Ihsen Alouani

Due to the multi-path propagation and extreme sensitivity to minor changes in the propagation medium, the coda waves open new fascinating possibilities in the non-destructive evaluation and acoustic imaging. However, their noise-like structure and high spurious sensitivity for ambient conditions (…

Thin-film adhesion: a comparative study between colored picosecond acoustics and spontaneous buckles analysis

Arnaud Devos, A. Vital-Juarez, A. Chargui, M.J. Cordill

This paper presents some quantitative measurements of the adhesion energy of thin WTi films deposited on Si substrate. Two different techniques are applied to the same sample series. One is a mechanical test based on the analysis of spontaneously formed defects. The second is based on acoustic…

In depth analysis of transfer length method application on passivated contacts under illumination

Léo Basset, Wilfried Favre, Olivier Bonino, Julien Sudre, Gilles Ménard, Jean-Pierre Vilcot

Although solar cells operate under illumination, most electrical characterization methods are carried out in darkness, which implies some bias. In this work, we study the influence of light on the contact resistivity of the electron and hole contacts of a silicon heterojunction (SHJ) cell using the…

Tubular phononic crystal sensor

A Gueddida, Yan Pennec, V Zhang, F Lucklum, M Vellekoop, N Mukhin, R Lucklum, Bernard Bonello, Bahram Djafari-Rouhani

We propose the design of a tubular phononic crystal (TPC) for the purpose of sensing the physical properties of a liquid filling the hollow part of the tube. The TPC is constituted by a periodic repetition of washers along a hollow pipe with the advantage of avoiding any perturbation of a flowing…

Performance Projection of GaN HEMT: Experimental Verification Using Curtice Model

Shariful Islam, Mohammad Abdul Alim, Anika Tahsin, Famin Rahman Rakib, Refat Uddin Rafi, Christophe Gaquière

This work deals with the performance projection of GaN HEMT towards experimental verification using Curtice model. To emphasize and identify their effects on the linear and saturation regions, we adjusted the three parameters employed in the Curtice model to fit the experimental data of the I-V…

Kinship verification between two people by machine learning, Vérification de la parenté entre deux personnes par aprentissage automatique

Oualid Laiadi

The kinship verification field attracted much attention in the few past years due to its capacity to improve biometrics systems as a soft biometric for face verification (kinship traits) and an important role in many society applications (kinship verification). Among these applications include the…, Le domaine de la vérification de la parenté a attiré beaucoup d’attention ces dernières années en raison de sa capacité à améliorer les systèmes biométriques en tant que biométrique souple pour la vérification du visage (traits de parenté) et un rôle important dans de nombreuses applications de la…
