Magnetic demultiplexer circuit with four channels

A. Mouadili, Abdellatif Akjouj, E. H. El Boudouti, L. Dobrzynski

We present a magnetic demultiplexer that allows us to transfer a magnon from one guide to another without perturbation the other guides. The proposed devise is formed by introducing a resonant system between two infinite guides. The resonant system has the role of coupling the guides to allow the…

Development of Ultrasonic Surface Acoustic Wave Humidity Sensors, Développement de Capteurs d’Humidité Ultrasonores à ondes Acoustiques de Surface

Saliou Ndao, Marc Duquennoy, Christian Courtois, Mohammadi Ouaftouh, Mohamed Rguiti, Nikolay Smagin, Frédéric Rivart, Maurice Gonon, Grégory Martic, Christine Pelegris, Frédéric Jenot

In a European project called CUBISM, humidity sensors based on IDT (Inter Digital Transducer) technology are developed for the generation and detection of surface acoustic waves (SAW). These sensors are designed to operate at high temperature (500°C) for monitoring the drying of refractory concrete…, Dans le cadre d’un projet européen nommé CUBISM, des capteurs d’humidité basés sur la technologie IDT (Inter Digital Transducer) pour la génération et la détection des ondes acoustiques de surface ou SAW (Surface Acoustic Wave) sont développés. Ces capteurs sont destinés à fonctionner à haute…

Heterologous biosynthesis of five new class II bacteriocins from Lactobacillus paracasei CNCM I-5369 with antagonistic activity against pathogenic Escherichia coli strains

Yanath Belguesmia, Kamel Bendjeddou, Isabelle Kempf, Rabah Boukherroub, Djamel Drider

Lactobacillus paracasei CNCM I-5369 isolated from a traditional Algerian dairy product produces extracellular inhibitory substances, namely, bacteriocins, which are active against a panel of pathogenic Escherichia coli strains. This activity was observed only at a narrow pH 4.5-5, and resulted to…

Tomographie passive par ondes élastiques guidées pour le Contrôle Santé des Structures

Bastien Chapuis, Tom Druet, Huu Tinh Hoang, Emmanuel Moulin

Les ondes élastiques guidées sont particulièrement adaptées pour les applications de contrôle santé de structures minces (type plaques, tubes ou cuves) grâce à leur capacité à se propager sur de longues distances. Cet article présente le développement d’une approche originale de contrôle santé des…, Elastic guided elastic waves show great potential for Structural Health Monitoring (SHM) of thin structures (plate-like, pipes or tanks) thanks to their ability to propagate over long distances. This article presents the development of a new approach for SHM called elastic guided waves passive…

Denoising higher-order moments for blind digital modulation identification in multiple-antenna systems

Sofiane Kharbech, Eric Pierre Simon, Akram Belazi, Wei Xiang

This letter proposes a new technique that substantially improves blind digital modulation identification (DMI) algorithms that are based on higher-order statistics (HOS). The proposed technique takes advantage of noise power estimation to make an offset on higher-order moments (HOM), thus getting…
