Hand-drawn face sketch recognition using rank-level fusion of image quality assessment metrics

Mahfoud Sami, Daamouche Abdelhamid, Bengherabi Messaoud, Abdenour Hadid

Face Sketch Recognition (FSR) presents a severe challenge to conventional recognition paradigms developed basically to match face photos. This challenge is mainly due to the large texture discrepancy between face sketches, characterized by shape exaggeration, and face photos. In this paper, we...

Towards highly efficient high power X‐band AlN/GaN MIS HEMTs operating above 50V

Kathia Harrouche, Sri Saran Vankatachalam, François Grandpierron, Etienne Okada, F Medjdoub

We report on AlN/GaN MISHEMT technology on SiC substrate for X-band applications. Transistors with 100 nm gate lengths deliver a high off-state breakdown voltage above 180V and 110 V in semi-on state. RF small signal measurements up to a drain bias (VDS) as high as 70V for two different gate...

Wearable Spoof Surface Plasmon Polariton Transmission Line

Ali Ghaddar, Baptiste Garnier, François Rault, Eric Lheurette, Ludovic Burgnies

In this work, we present a study of Spoof Surface Plasmon Polari-ton (SSPP) supported by a meandered Transmission Line (TL) dedicated to wireless body sensor network applications. First, dispersion curves evidence the existence of a surface wave propagation, called odd mode according to the...

Vocabulary to speak about touch: analysis of the discourse of electric guitar players

Paul Cambourian, Arthur Paté, Caroline S. Cance, Benoît Navarret, Jerome O. Vasseur

This work presents a multidisciplinary approach to vibrotactile perception, applying linguistic methods to musical acoustics. We are interested more particularly in the sense of touch as a part of the multisensory experience of playing a musical instrument. Six words and their inflections are...

Parametric excitation of a gravity–capillary wave by radiation pressure of ultrasound

Leonid Krutyansky, Vladimir L. Preobrazhensky, Andrey Brysev, Philippe Pernod, R. Klopotov

Parametric instability of a standing gravity–capillary wave is observed in conditions of irradiation of a surface of a liquid by a plane ultrasound beam modulated by amplitude. A threshold value of ultrasound intensity for excitation of the parametric oscillations of the surface is determined, and...

Multimode propagation in phononic crystals with overlapping Bragg and hybridization effects

Charles Croënne, E. J. S. Lee, J. H. Page

Unusual dispersion properties are observed in a phononic crystal of nylon rods in water when the lattice constant is adjusted so that Bragg and hybridization gaps overlap in frequency. On the basis of experimental and numerical analyses of time-dependent transmission and spatial field maps, the...

3D tensegrity braces with superelastic response for seismic control

Filipe Santos, Catarina Caroço, Ada Amendola, M. Miniaci, Fernando Fraternali

Tensegrity structures have recently shown great potential as bracing devices for seismic control due to their unique ability to passively dissipate energy in structures subjected to severe deformations. Indeed, behaving as nonlinear springs, they are able to dissipate a great amount of energy...

100 Gbit/s THz Data Transmission and Beyond using Multicore Fiber Combined with UTC Photodiode Array

Alfred Bewindin Sawadogo, Aritrio Bandyopadhyay, Malek Zegaoui, Mohammed Zaknoune, P. Szriftgiser, Karen Baudelle, Monika Bouet, Géraud Bouwmans, Davy Gaillot, Esben Ravn Andresen, Guillaume Ducournau, Laurent Bigot

Photonics-driven transmitters are leading the race towards high data-rates at THz frequencies. Here, spatial-multiplexing based on multicore fiber and photodiodes array is considered to alleviate the limited output power. Sub-systems have been developed and validated.

Switchability of a single port SAW resonator using the electrical Bragg band gap

R. Alcorta Galván, Charles Croënne, Bertrand Dubus, B. Loiseaux, E. Eustache, M. Bertrand, Anne-Christine Hladky

A proof of concept of a new solution for achieving tunable SAW components based on the electrical Bragg band gap concept developed for piezoelectric phononic crystals is presented on a SAW resonator on a LiNbO3 substrate. In this work, it is shown that for a fixed geometry, it is possible to shift...

De la théorie à la pratique dans l’enseignement du traitement du signal : initiation à la recherche

Lynda Chehami, Nikolay Smagin, Jamal Assaad, Pierre Campistron, Frédéric Jenot, Emmanuel Moulin

Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la...
