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...

Tuning the Cation Ordering with the Deposition Pressure in Sputtered LiMn1.5Ni0.5O4 Thin Film Deposited on Functional Current Collectors for Li-Ion Microbattery Applications

Manon Létiche, Maxime Hallot, Marielle Huve, Thierry Brousse, Pascal Roussel, C. Lethien

The development of high voltage spinel LiMn1.5Ni0.5O4 (LMNO) sputtered thin films on functional current collector was reported within the framework of this study. We have first solved the technological issue due to the PtSi phase which originates from the interdiffusion between silicon wafer and...

Low Complexity Joint Blind Equalization and CFO Estimation for MC-CDMA System

Kais Bouallegue, Iyad Dayoub, M Gharbi, Kaïs Hassan, R. Masmoudi, A. Djebbar

Based on the orthogonality between the used and the unused spreading codes (excess codes) subspaces in one hand and on the restoration of guard interval redundancy of Multicarrier Code Division Multiple Access signal in other hand, we propose joint Carrier Frequency Offset and time domain equalizer...

Design, fabrication and characterization of a new wideband antenna based on a Polyaniline/Carbon coated Cobalt composite

Z. Hamouda, J.-L. Wojkiewicz, A.A. Pud, Lamine Kone, S. Bergheul, T. Lasri

The new generation of polymer materials has the facility to conduct electricity, radiate and concurrently be flexible. Accordingly, the possibility of implementation of a flexible antenna opens the door to many interesting applications including body-worn ones. This paper presents the design of a...

Microfabricated PEDOT trilayer actuators: synthesis, characterization, and modeling

Ngoc Tan Nguyen, Cedric Plesse, Caroline Soyer, Sébastien Grondel, John D.W. Madden, Eric Cattan, Frédéric Vidal

Conducting polymer actuators have long been of interest as an alternative to piezoelectric and electrostatic actuators due to their large strains and low operating voltages. Recently, poly (3,4-ethylenedioxythiophene) (PEDOT) - based ionic actuators have been shown to overcome many of the initial...
