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…

Experimental Study of Passive Defect Detection and Localization in Thin Plates from Noise Correlation

Lynda Chehami, Emmanuel Moulin, Julien de Rosny, Claire Prada, Jamal Assaad, Farouk Benmeddour

This paper reports experimental results on a passive imaging technique for structural health monitoring to detect the occurrence of defects in plate-like structures. This technique is based on the fact that the active transient response between two sensors can be passively retrieved by cross-…

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,…

Source identification for the wave equation on graphs

Sergei Avdonin, Serge Nicaise

We consider source identification problems for the wave equation on graphs. The main advantage of our approach is its locality. Our algorithm reduces essentially to the resolution of linear integral Volterra equations of the second kind and is new even for an interval.

Bilateral Strength Deficit Is Not Neural in Origin; Rather Due to Dynamometer Mechanical Configuration

Emilie Simoneau-Buessinger, Sebastien Leteneur, Anis Toumi, Alexandra Dessurne, François Gabrielli, Franck Barbier, Jennifer Jakobi

During maximal contractions, the sum of forces exerted by homonymous muscles unilaterally is typically higher than the sum of forces exerted by the same muscles bilaterally. However, the underlying mechanism(s) of this phenomenon, which is known as the bilateral strength deficit, remain equivocal.…
