Development of an highly distributed photoconductor for CW THz generation

F. Bavedila, Vincent Magnin, Joseph Harari, Dmitri Yarekha, David Troadec, Sylvie Lepilliet, Vanessa Avramovic, Guillaume Ducournau, Jean-Francois Lampin, Emilien Peytavit

In this communication, we propose a new architecture of photomixer in order to develop a wideband and powerful photomixing THz source. It is achieved by a velocitymatched distributed photoconductor (VMDP), in which the pump optical power is guided in a dielectric optical guide and slightly coupled...

Cross-layer approach dedicated to HEVC low delay temporal prediction structure streaming over VANETs

Mohamed Aymen Labiod, M Gharbi, François-Xavier Coudoux, Patrick Corlay, Noureddine Doghmane

High-quality delivery of compressed video over vehicular networks is a very challenging task. In this paper, we propose a cross-layer mechanism dedicated to high-efficiency video coding (HEVC) low delay temporal prediction structure in order to improve the video transmission through vehicular ad-...

Développement de micro-capteurs de frottement pariétal et de pression pour les mesures en écoulements turbulents et le contrôle de décollement, Development of wall shear stress and pressure micro-sensors for turbulent flows measurements and flow control

Cécile Ghouila-Houri

Le contrôle des écoulements vise à modifier le comportement naturel d’un écoulement fluidique. Dans le domaine des transports, contrôler les phénomènes fluidiques tels que le décollement peut permettre d’économiser du carburant, d’améliorer les performances des véhicules ou encore d’assurer..., Flow control aims at artificially changing the natural behaviour of a flow. In transport industries, controlling fluidic phenomena such as boundary layer separation allows saving fuel and power, improving vehicles performances or insuring passenger’s safety. In this context, sensors with accurate...

Demonstration of Magnetoplasmon Polariton at InSb/dielectric Interface

Jan Chochol, Martin Micica, Kamil Postava, Mathias Vanwolleghem, Jean-Francois Lampin, Michael Cada, Jaromir Pistora

Abstract: A surface plasmon resonance (SPR) in terahertz range is demonstrated in InSb. Using an Otto configuration, the surface plasmon is excited on the interface between semiconductor and a thin polymer film by silicon prism. Due to the low effective mass of InSb it is possible to tune SPR by an...

2D and 3D Palmprint Recognition using Deep Learning Method

Djamel Samai, Khaled Bensid, Abdallah Meraoumia, Abdelmalik Taleb-Ahmed, Mouldi Bedda

In the last years, several researchers have interested in two-dimensional (2D) palmprint recognition. In order to enhance the security of biometric systems, recently, some works proposed to use three-dimensional (3D) palmprint recognition. The advantage of using the 3D capture systems is that they...
