Multiple description coding and scalable video coding combined with multiple input multiple output techniques : two strategies to enhance train to wayside video transmissions in tunnels

Imade Fatani, Yann Cocheril, Crépin Nsiala-Nzéza, Marion Berbineau, François-Xavier Coudoux, Marie Zwingelstein, Patrick Corlay

Video monitoring applications for underground rely on wireless train-to-wayside communication systems which require high data rate as well as high Quality of Service (QoS) level. In order to satisfy both constraints we propose a combined source and channel coding approach in the context of MIMO (…

Negative refraction of elastic waves in 2D phononic crystals : contribution of resonant transmissions to the construction of the image of a point source

Anne-Christine Hladky, Charles Croënne, Bertrand Dubus, Jerome O. Vasseur, L. Haumesser, D. Manga, B. Morvan

Negative refraction properties of a two-dimensional phononic crystal (PC), made of a triangular lattice of steel rods embedded in epoxy are investigated both experimentally and numerically. First, experiments have been carried out on a prism shaped PC immersed in water. Then, for focusing purposes…

Inter-Model Consistency and Complementarity: Learning from ex-vivo Imaging and Electrophysiological Data towards an Integrated Understanding of Cardiac Physiology

Oscar Camara, Maxime Sermesant, P. Lamata, L. Wang, Mihaela Pop, Jatin Relan, Mathieu de Craene, Hervé Delingette, H. Liu, S. Niederer, A. Pashaei, G. Plank, D. Romero, R. Sebastian, Ken C.L. Wong, H. Zhang, Nicholas Ayache, Alejandro Frangi, P. Shi, Nic Smith, Graham Wright

Computational models of the heart at various scales and levels of complexity have been independently developed, parameterised and validated using a wide range of experimental data for over four decades. However, despite remarkable progress, the lack of coordinated efforts to compare and combine…

Thermal characterization of MBE-grown GaN/AlGaN/GaN device on single crystalline diamond

J. Kuzmik, S. Bychikhin, D. Pogany, E. Pichonat, O. Lancry, Christophe Gaquière, G. Tsiakatouras, G. Deligeorgis, A. Georgakilas

Self-heating effects in a molecular beam epitaxy-grown GaN/AlGaN/GaN structure on a single crystalline diamond is investigated. A transient interferometric method, in combination with a three dimensional model, is used to describe a pulsed operation of a transistor-like heater, and a micro-Raman…

Demonstration of low leakage current and high polarization in ultrathin AlN/GaN high electron mobility transistors grown on silicon substrate

F Medjdoub, Malek Zegaoui, N. Rolland, Paul-Alain Rolland

High quality AlN/GaN heterostructures grown on silicon substrate are demonstrated. It is found that high carrier concentration can be achieved whereas circular diodes showed a low leakage current up to 200 V reverse bias. 200 nm gate length AlN/GaN transistors exhibited a drain current density of 1…

Dielectric dispersion of BaSrTiO3 thin film from centimeter to submillimeter wavelengths

Grégory Houzet, Karine Blary, Sylvie Lepilliet, Didier Lippens, Ludovic Burgnies, Gabriel Vélu, Jean-Claude Carru, Edwin Nguema Agnandji, Patrick Mounaix

The dielectric dispersion of ferroelectric BaxSr1-xTiO3 (BST) thin film in a paraelectric phase was characterized from centimeter to submillimeter wavelengths. To this aim, interdigitated capacitors were patterned on a micrometer scale onto a BST layer with a barium concentration of 0.5 and were…
