METASTABILITY OF FINITE STATE MARKOV CHAINS: A RECURSIVE PROCEDURE TO IDENTIFY SLOW VARIABLES FOR MODEL REDUCTION

Claudio Landim, T. Xu

Consider a sequence (η N (t) : t ≥ 0) of continuous-time, irreducible Markov chains evolving on a fixed finite set E. Denote by R N (η, ξ) the jump rates of the Markov chain η N t , and assume that for any pair of bonds (η, ξ),

DS-UWB and TH-UWB Energy Consumption Comparison

Adil Elabboubi, Fouzia Elbahhar, Marc Heddebaut, Yassin El Hillali

The energy consumption of the wireless communication systems is starting to be unaffordable. One way to improve the power consumption is the optimization of the communication techniques used by the communication networks and devices. In order to develop an energy efficient UWB multi-user…

Magnetic-Phase Dependence of the Spin Carrier Mean Free Path in Graphene Nanoribbons

Jing Li, Yann-Michel Niquet, Christophe Delerue

We show theoretically that the intrinsic (phonon-limited) carrier mobility in graphene nanoribbons is considerably influenced by the presence of spin-polarized edge states. When the coupling between opposite edges switches from antiferromagnetic to ferromagnetic with increasing carrier density, the…

AlN/IDT/AlN/Sapphire SAW Heterostructure for High-Temperature Applications

Ouarda Legrani, Thierry Aubert, Omar Elmazria, Ausrine Bartasyte, Pascal Nicolay, Abdelkrim Talbi, Pascal Boulet, Jaafar Ghanbaja, Denis Mangin

Recent studies have evidenced that Pt/AlN/Sapphire SAW devices are promising for high-temperature high-frequency applications. However, they cannot be used above 700°C in air atmosphere as the Pt interdigital transducers (IDTs) agglomerate and the AlN layer oxidizes in such conditions. In this…

Containment nuclear plant structures evaluation by non destructive testing: strategy and results

Vincent Garnier, Jean-Marie Henault, Hamid Hafid, Jérôme Verdier, Jean François Chaix, Odile Abraham, Zoubir Medhi Sbartaï, Jean-Paul Balayssac, Bogdan Piwakowski, Géraldine Villain, Xavier Derobert, Cédric Payan, Sandrine Rakotonarivo, Éric Larose, Hognon Sogbossi, Quang Anh Vu, Martin Lott, Jean-Baptiste Legland, Olivier Durand, Radoslaw Drelich, Charles Ciccarone

Containment nuclear plants structures are an ultimate barrier in the event of an accident. Mechanical resistance and tightness are the two functions that they are expected to provide. To evaluate their capacity to perform them, destructive testing cannot be used to characterize the material. Non-…

Toward Energy Profiling of Connected Embedded Systems

Nadir Cherifi, Gilles Grimaud, Alexandre Boé, Thomas Vantroys

A huge number of connected objects are expected to be deployed over the coming years in various areas of everyday life. Many of these objects are energy-constrained and depend on a battery. Thus, energy is a critical resource that limits a large scale deployment, and greatly complicates the…

Mode-hopping suppression in long Brillouin fiber laser with non-resonant pumping

Gwennaël Danion, Ludovic Frein, Denis Bacquet, Grégoire Pillet, Stéphanie Molin, Loïc Morvan, Guillaume Ducournau, Marc Vallet, Pascal Szriftgiser, Mehdi Alouini

We propose a reliable method for stabilizing narrow linewidth Brillouin fiber lasers with non-resonant pumping. Mode-hopping is suppressed by means of a phase-locked loop that locks the pump-Stokes detuning to a local radio-frequency (RF) oscillator. Stable single-mode operation of a 110-m-long…
