Numerical study of the reflected elastic waves using Rayleigh diffraction integral

Nadir Maghlaoui, Hakim Djelouah, Assia Oudina, Mohamed Ourak, Farouk Benmeddour

In this work, the transient ultrasonic waves radiated by a linear phased array transducer in a liquid then reflected at a liquid solid interface is studied. A model based on the Rayleigh integral is used where the reflection at the plane interface is considered by using the reflection coefficients…

Influence of surface texturing on the biocompatibility of breast implants, Influence de la texturation de surface sur la biocompatibilité des implants mammaires

Charles Garabedian

The first breast implant surface pattern approved by the American Food and Drug Administration (FDA) is Biocell texture commercialized by the American company Allergan in 1987. Most breast implant manufacturers then adopted similar surface patterning process. A report from the Agence Nationale de…, La première structuration de surface d’implants mammaires approuvée par l’agence sanitaire américaine Food and Drug Administration (FDA) est la texturation Biocell de l’Américain Allergan en 1987. La plupart des fabricants d’implants mammaires ont ensuite adopté des procédés permettant d’obtenir…

FPGA Implementation of a Novel Construction of Optical Zero-Correlation Zone Codes for OCDMA Systems

Samia Driz, Benattou Fassi, Mohammed Amine Mansour, Abdelmalik Taleb-Ahmed

This paper proposes a novel method for constructing optical zero-correlation zone (OZCZ) codes based on the Mutually Orthogonal Complementary Sets (MOCS) matrix and the concatenation operation. The most important property of the obtained codes is that the periodic correlation function of the…

Optimal Direct Adaptive Fuzzy Controller based on Bat Algorithm for UAV Quadrotor

Hossam Eddine Glida, Latifa Abdou, Abdelghani Chelihi, Chouki Sentouh

An optimal direct robust adaptive fuzzy controller (ODAFC) for a quadrotor system using bat algorithm (BA) is presented in this paper. The concept of this approach is to decouple the entire system into four single-input single-output (SISO) subsystems. Then, a Mamdani-type fuzzy adaptive controller…

Contribution à la modélisation des chaînes informationnelles et des processus décisionnels associés à un produit "intelligent, Contribution to the modelling of information chains and decision making processes associated with an « intelligent » product

Vivien Basselot

Ces dernières années, les produits dits « intelligents » ont été introduits dans de nombreux domaines tels que l’industrie, la santé et le transport. Ces produits sont devenus sources d’informations durant leurs phases d’utilisations. L’obtention de ces informations constitue un avantage certain…, In recent years, “smart products” have been introduced in many areas such as industry, health and transportation systems. These products are sources of information during their use phases. Collecting, processing this information is a definite advantage to aid the various stakeholders involved in…

Design and Creation of a Wearable Circular Ultrasonic Device for a Soft Screening and Diagnosis of Breast Abnormalities

Amira Godih, Georges Nassar, Toshima Z Parris, Nadine Saad, Elie Helou, Per Karlsson, Khalil Helou

An ultrasound breast imaging system was implemented comprising sensors with a wide lateral radiation field distributed at equal distances on rings of different diameters covering the breast. The Green function was derived to calculate the acoustic field generated by these transducers when they were…

Modeling and Control of Rehabilitation Robotic Device: motoBOTTE

Juan Carlos Arceo Luzanilla, Jimmy Lauber, Lucien Robinault, Sebastien Paganelli, Mads Jochumsen, Imran Khan Niazi, Emilie Simoneau-Buessinger, Sylvain Cremoux

The motoBOTTE is a robot designed for assistive rehabilitation. The identification of a mathematical model for the system is shown; then we design and implement a nonlinear control law for tracking a reference signal. The nonlinear controller design is achieved by combining an exact convex…

Overview on HEVC Inter Frame Video Coding’s Impact on the Energy Consumption for Next Generation WVSNs

Achraf Ait-Beni-Ifit, Othmane Alaoui-Fdili, Patrick Corlay, François-Xavier Coudoux, Mohammed El Hassouni

With the advent of the High Efficiency Video Coding HEVC standard, wireless transmission of video data consumes more and more energy, a major concern in the field of Wireless Video Sensor Networks (WVSNs). The energy resources are limited, consisting only in the battery of the sensor nodes that…
