Numerical simulation of the transient ultrasonic wave reflection at a liquid-solid interface

Nadir Maghlaoui, Hakim Djelouah, Mohamed Ourak, Djema Belgroune

In the nondestructive evaluation domain, the reflection of ultrasonic waves at liquid-solid interfaces generates interesting and useful phenomena when the incident angle approaches the longitudinal critical angle or Rayleigh angle. In this paper, we have developed a model for the study of the…

Effects of robotic gait rehabilitation on biomechanical parameters in the chronic hemiplegic patients, Effets de la rééducation robotisée à la marche sur les paramètres biomécaniques de la marche chez des patients hémiplégiques chroniques

Laura Wallard, Gilles Dietrich, Yves Kerlirzin, Jonathan Bredin

Hemiplegia is a more or less complete loss of hemibody voluntary motricity following a brain injury, usually resulting in alterations of the locomotor system with persistent disorders of movement and posture. We were interested in studying the gait pattern called "stiff knee gait" with…, L’hémiplégie est une perte plus ou moins complète de la motricité volontaire d’un hémicorps suite à une lésion cérébrale, entraînant généralement des altérations de l’appareil locomoteur avec des troubles persistants du mouvement et de la posture. Nous nous sommes intéressés, pour cette étude, au…

Acousto-Optical Tunable Transmissive Grating Beam Splitter

Anthony Dieulangard, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

We present a tunable transmissive grating beam splitter for multiple laser line separation based on acousto-optic interaction in tellurium dioxide. Acousto-optic devices are well known for light modulation, frequency shifting, filtration or deflection. For a deflector, the incident light beam is…

Axisymmetric modeling of the thermal cooling, including radiation, of a circular glass disk

Norbert Siedow, Dominique Lochegnies, Fabien Béchet, Philippe Moreau, Hiroshi Wakatsuki, Nobuhiro Inoue

Achieving correct tempering in thin glass is very important to prevent undesired stress and breakage. Computer simulation can elucidate and control the tempering process. For semitransparent materials like glass, heat transfer by thermal radiation is substantial; for thick glass, it may dominate…

Stabilization and asymptotic behavior of a generalized telegraph equation

Serge Nicaise

We analyze the stability of different models of the telegraph equation set in a real interval. They correspond to the coupling between a first-order hyperbolic system and a first-order differential equation of parabolic type. We show that some models have an exponential decay rate, while other ones…

Evaluating User Interface Adaptation using the Context of Use

Makram Soui, Khaled Ghedira, Mourad Abed

The aim of adaptive user interface is to provide different layouts and relevant information according to the current context-of-use (users, platforms and environments). Today, these systems are indispensable to those who want to retrieve appropriate information with less effort at anytime and…

Transmitted torque observer applied to real time engine and clutch torque estimation

Rémi Losero, Jimmy Lauber, Thierry-Marie Guerra

In automation control system applications, the transmitted engine and clutch torque are unavoidable information for the control strategies. For example, these information are required to engine control, hybrid vehicle and automated transmission management. An angular domain discrete observer is…

Wave propagation in graded rings with rectangular cross-sections

J.G. Yu, X.D. Yang, Jean-Etienne Lefebvre, Ch. Zhang

In this paper, a double orthogonal polynomial series method is proposed to investigate the guided wave propagation in a two-dimensional (2-D) structure, namely, a FGM ring with a rectangular cross-section. Two kinds of graded rings are considered: material gradient directions being in the radial…

Wave propagation in functionally graded piezoelectric rods with rectangular cross-section

J.G. Yu, Zhang Bo, Jean-Etienne Lefebvre, C. Zhang

For the purpose of design and optimization of functionally graded piezoelectric material (FGPM) transducers, wave propagation in FGPM structures has received much attention in the past twenty years. But research focused essentially on semi-infinite structures and one-dimensional structures, i.e.,…

Ultrasonic reflectometry in air: errors of sample positioning

Mariusz Kaczmarek, Bogdan Piwakowski, Radoslaw Drelich

The reflection coefficient of ultrasonic waves propagating in air and interacting with a plane surface of a solid is considered. The simulation of dependence of the reflection coefficient on errors of sample positioning is performed using a finite beam model along with an angular spectrum method,…
