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...

Advancements on the molecular design of nanoantibiotics: current level of development and future challenges

Roxana Jijie, Alexandre Barras, Florina Teodorescu, Rabah Boukherroub, Sabine Szunerits

Numerous antimicrobial drugs have been developed and commercialized to kill and inhibit the growth of pathogenic microbes. The therapeutic efficiency of these drugs has however become often inadequate for the treatment of microbial infections, the reasons being multiple. Oral administration results...

An ultra broadband 0.5-18 GHz BPSK modulator

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5 - 18 GHz frequency bandwidth. Experimental results...

Separation of two fractions of immiscible liquids by ultrasound in microgravity

Leonid Krutyansky, Farzam Zoueshtiagh, Philippe Pernod, P. Shirkovskiy, Andrey Brysev

Ultrasonic separation of two immiscible liquids under microgravity conditions has been demonstrated on example of liquid mixtures of FC-70 or FC-72 with silicone oils of 1.5 or 1.0 cSt viscosities, respectively. A 3-MHz focused ultrasound beam was utilized to form an emulsion from these liquid...

Coupling of two resonant modes for insect wing mimicking in a flexible-wing NAV and generate lift

Damien Faux, Eric Cattan, Sébastien Grondel, Olivier Thomas

This work is based on the original concept of coupling two resonant vibration modes to reproduce insect wing kinematics and generate lift. The key issue is designing the geometry and the elastic properties of the artificial wings to achieve quadrature coupling of the bending and twisting motions...

IoT predictive application for DC motor control using radio frequency links

R. Kouki, A. Boé, T. Vantroys, F. Bouani

The Internet of things (IoT) becomes a new solution for the future industry. It aims to provide an intelligent environment to control systems in real time. We propose an embedded predictive application in the Wireless Networked Control Systems (W-NCS) to control a DC motor via RF links, under the...
