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...

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...

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....

Optimization of matching and scheduling on heterogeneous CPU/FPGA architectures

Omar Souissi, Rabie Ben Atitallah, David Duvivier, Abdelhakim Artiba

The continuous improvements in several application domains such as telecommunications, aerospace or multimedia lead to additional design constraints on power budget and architecture scalability. The heterogeneous CPU/FPGA (Central Processing Unit/Field-Programmable Gate Array) architecture is one...

A simple real-time aerodynamic model for vehicles in overtaking situations

Fredrik Bruzelius, David Uystepruyst, Bengt Jacobson, Siniša Krajnovic

Aerodynamic forces and moments play an important role in overtaking situations and affect the trajectory of the involved vehicles. One method of studying these effects and how the driver responds to these is via driving simulator studies. However, models that describe aerodynamic forces and moments...

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...

Takagi-Sugeno Fuzzy Representation to Modelling and State Estimation

Mohammed Chadli, Thierry-Marie Guerra, Ivan Zelinka

This chapter shows the interest of Takagi-Sugeno (T-S) fuzzy model approach to apprehend nonlinear behaviors of physical systems and its application for observers design. From mathematical nonlinear model or experimental data, a T-S representation can be obtained using different techniques. This...

Spectral analysis and exponential or polynomial stability of some indefinite sign damped problems

F. Abdallah, D. Mercier, Serge Nicaise

In this paper, we consider two damped wave problems for which the damping terms are allowed to change their sign. Using a careful spectral analysis, we find critical values of the damping coefficients for which the problem becomes exponentially or polynomially stable up to these critical values.

Option pricing with constant elasticity of variance (CEV) model

Rajae Aboulaich, M. L. Hadji, Abdelilah Jraifi

In this work we propose an approximate numerical method for pricing of options for the constant elasticity of variance (CEV) diffusion model. We prove firstly the existence and uniqueness of the solution in weighted Sobolev space, and then we propose the finite element method and finite difference...
