New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

Eloïse Vidal, Nicolas Sturmel, Christine Guillemot, Patrick Corlay, François-Xavier Coudoux

In this paper, we introduce two perceptual filters as pre-processing techniques to reduce the bitrate of compressed high-definition (HD) video sequences at constant visual quality. The goal of these perceptual filters is to remove spurious noise and insignificant details from the original video…

Luminescence imaging of photoelectron spin precession during drift in a p-type GaAs microfabricated Hall bar

V. Notot, D. Paget, A. Rowe, L. Martinelli, Fabian Cadiz, S. Arscott

Using a microfabricated p-type GaAs Hall bar, it is shown that the combined application of co-planar electric and magnetic fields enables the observation of spatial oscillations of the photoluminescence circular polarization due to the precession of drifting spin-polarized photoelectrons.…

IEEE 802.11n Communications in the Presence of Frequency-Sweeping Interference Signals

Virginie Deniau, Christophe Gransart, Grecia Romero, Eric Pierre Simon, Joumana Farah

This paper presents an analysis of the impact of intentional electromagnetic (EM) interferences on the performance of Wi-Fi communications. The goal is to analyze the susceptibility of orthogonal frequency-division multiplexing (OFDM) signals and to understand how certain parameters of the…, Cet article présente une analyse de l'impact des interférences électromagnétiques intentionnelles (IEMI) sur la performance des communications Wi-Fi. L'objectif est d'analyser la susceptibilité des signaux de OFDM (Orthogonal Frequency Division Multiplex ) et de comprendre comment…

Complexity of the hot carrier relaxation in Si nanowires compared to bulk

Jing Li, Yann-Michel Niquet, Christophe Delerue

We investigate the relaxation of hot carriers by emission of phonons in bulk Si and Si nanowires (NWs) with an identical atomistic methodology. The phonon scattering is strongly enhanced in NWs. At high excitation energy, the carrier cooling is faster in NWs than in bulk, mainly due to the coupling…

Energy Consumption Models For MISO-UWB and TR-MISO-UWB Systems

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

this paper, an energy consumption model is developed and exploited to evaluate the electrical energy consumption of ultra-wideband impulse radio (UWB-IR) systems. We develop the energy consumption models and our comparative study, on the one hand, for a system based single-input singleoutput (SISO…

A 4-fJ/spike artificial neuron in 65 nm CMOS technology

Ilias Sourikopoulos, Sara Hedayat, Christophe Loyez, Francois Danneville, Virginie Hoel, Eric Mercier, A. Cappy

As Moore's law reaches its end, traditional computing technology based on the Von Neumann architecture is facing fundamental limits. Among them is poor energy efficiency. This situation motivates the investigation of different processing information paradigms, such as the use of spiking neural…

Iron minerals within specific microfossil morphospecies of the 1.88 Ga Gunflint Formation

Kevin Lepot, Ahmed Addad, Andrew H. Knoll, Jian Wang, David Troadec, Armand Béché, Emmanuelle J. Javaux

Problematic microfossils dominate the palaeontological record between the Great Oxidation Event 2.4 billion years ago (Ga) and the last Palaeoproterozoic iron formations, deposited 500-600 million years later. These fossils are often associated with iron-rich sedimentary rocks, but their affinities…
