Stabilization by switching time–delay

Kaïs Ammari, Serge Nicaise, Cristina Pignotti

In this paper we consider some stabilization problems for the wave equation with switching time-delay. We prove exponential stability results for appropriate damping coefficients. The proof of the main results is based on D'Alembert formula, observability inequality and some energy estimates.…

Optimal Design of a High Performance Haptic Device

Quoc Viet Dang, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

Stability and transparency are very important performance measures in the design of haptic devices. This paper addresses the design of haptic device in the case of interaction to a virtual wall. A novel optimal design method for high performance (stability and low inertia) haptic devices is…

Realizable Galois module classes over the group ring for non abelian extensions, Classes galoisiennes réalisables sur l’anneau de groupe d’extensions non abéliennes

Nigel Byott, Bouchaïb Sodaïgui

Given an algebraic number field k and a finite group T, we write R(Ok[T]) for the subset of the locally free classgroup Cl(Ok[T]) consisting of the classes of rings of integers ON in tame Galois extensions N/k with Gal(N/k) T = T. We determine R(Ok[T]), and show it is a subgroup of Cl(Ok[T]) by…

A Web questionnaire generating tool to aid for interactive systems quality subjective assessment

Ahlem Assila, Houcine Ezzedine, Mohamed Salim Bouhlel

This paper is related to the Human-Computer Interaction (HCI) field and more specifically to the interactive system quality evaluation using a subjective method known by the questionnaire. Efforts and research have been performed to enhance subjective usability evaluation of Human — Computer…

On the asymptotic behavior of transmission thin shell problems

Ismail Merabet, Serge Nicaise, D.A. Chacha

In this paper we study the asymptotic behavior of two-dimensional transmission problems for the linear Koiter model of an elastic multi-structure composed of two thin shells with the same thickness ε<<1. Contrary to the case of membrane shells, the formal limit problem, i.e., for ε=0, fails…

Towards large time simulation reduction for the solving of mechanical contact (large scale) problems: A robust control approach

Antonio Gonzalez Sorribes, Jimmy Lauber, Thierry-Marie Guerra, Franck Massa, Thierry Tison

The evolution of computational resources contributes to the use, more and more frequent, of mechanical contact in numerical models. The main difficulty is to determine rapidly the contact loads which allow balancing two structures, modeled by the finite element method. This problem is reported to…
