FEM Simulation Based on CAD Model Simplification: A Comparison Study between the Hybrid Method and the Technique Using a Removing Details

Mounir Hamdi, Nizar Aifaoui, Borhen Louhichi, Abdelmajid Benamara, Dominique Deneux

The simulation process is currently used in the design and dimensioning of mechanical parts. With the progress of computer materials, the Finite Elements Method (FEM) becomes the most used approach in the simulation of mechanical behavior. The simulation process needs multiple Design-FEM loops. In…

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…

On Riemann and Weyl compatible tensors

Ryszard Deszcz, Małgorzata Głogowska, Jan Jełowicki, Miroslava Petrović-Torgašev, Georges Zafindratafa

We investigate semi-Riemannian manifolds satisfying some curvature conditions. Those conditions are strongly related to pseudosymmetry.

Robust Approximation of Singularly Perturbed Delay Differential Equations by the hp Finite Element Method

Serge Nicaise, Xenophontos Christos

Abstract. We consider the finite element approximation of the solution to a singularly perturbed second order differential equation with a constant delay. The boundary value problem can be cast as a singularly perturbed transmission problem, whose solution may be decomposed into a smooth part, a…

Estimation of Road Adhesion Coefficient Using Higher-Order Sliding Mode Observer for Torsional Tyre Model

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, D. Zhang, Q. Zhang, Michael Defoort

The estimation of friction coefficient for a vehicle when it traverses on different surfaces has been an important issue. In this paper, a super-twisting algorithm based sliding mode observer is proposed to estimate the road adhesion coefficient, treated as an unknown input in the dynamics of a…

Variable neighborhood search for location routing

Bassem Jarboui, Houda Derbel, Said Hanafi, Nenad Mladenovic

In this paper we propose various neighborhood search heuristics (VNS) for solving the location routing problem with multiple capacitated depots and one uncapacitated vehicle per depot. The objective is to find depot locations and to design least cost routes for vehicles. We integrate a variable…
