Energy Efficient Hardware and Improved Cluster-Tree Topology for Lifetime Prolongation in ZigBee Sensor Networks

Mourad Ouadou, Ouadoudi Zytoune, Yassin El Hillali, Atika Rivenq, Driss Aboutajdine

In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries. Many factors are involved in the energy consumption, and this issue may be considered as a cross-layer problem, from the…

Simulation Study of the Localization of a Near-Surface Crack Using an Air-Coupled Ultrasonic Sensor Array

Steven Delrue, Vladislav Aleshin, Mikael Sørensen, Lieven Lathauwer

The importance of Non-Destructive Testing (NDT) to check the integrity of materials in different fields of industry has increased significantly in recent years. Actually, industry demands NDT methods that allow fast (preferably non-contact) detection and localization of early-stage defects with…

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.…

Finite element modeling of a piezoelectric slender bar transducer equipped with a multilayer backing for medical imaging applications

Nadia El Atlas, Abdelmajid Bybi, Hilal Drissi, Anne-Christine Hladky

The goal of this work is to investigate the impact of front and back matching layers properties on a piezoelectric slender bar transducer performances and to propose a novel multilayer backing absorber. Quarter-wavelength acoustic matching layers and backing are known as essential components to…

On demand electrochemical release of drugs from porous reduced graphene oxide modified flexible electrodes

Samia Boulahneche, Roxana Jijie, Alexandre Barras, Fereshteh Chekin, Santosh K Singh, Julie Bouckaert, Mohamed Salah Medjram, Sreekumar Kurungot, Rabah Boukherroub, Sabine Szunerits

Despite the advantages of an electrochemical control for drug release, only a handful of electrochemical-based release systems have been developed so far. We report herein on the development of an electrochemically activatable platform for on-demand delivery of drugs. It is based on flexible gold…

Experimental investigation of stochastic resonance in a 65 nm CMOS artificial neuron

Sara Hedayat, Ilias Sourikopoulos, Christophe Loyez, Francois Danneville, Laurent Clavier, Virginie Hoel, A. Cappy

This work proposes an experimental demonstration of the stochastic resonance, a phenomenon widely observed in biology using a 65 nm CMOS artificial neuron. The stochastic resonance has been revealed through two different statistical studies. Moreover, when optimal, a signal to noise ratio at the…
