Regularity of solutions of elliptic or parabolic problems with Dirac measures as data

S. Ariche, Colette De Coster, Serge Nicaise

In this paper we study the Laplace and heat equations with Dirac right-hand side. We prove some regularity results in a scale of weighted Sobolev spaces, the weight being the distance to the support of the right-hand side. Model situations in dimension three are treated by using Fourier, Laplace or...

Exergy assessment of heat transfer inside a Beta type Stirling engine

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah, Ibrahim Dincer

This paper presents an assessment of both energy and exergy efficiencies of a Beta Stirling engine prototype with a 30 W capacity as the maximum mechanical power output. Its operating pressure is close to atmospheric pressure, and it supports a maximum hot end temperature of 650 degrees C. The...

Behaviour of flow dynamics over an asymmetrical deep cavity at high reynolds numbers

Denis Cornu, Laurent Keirsbulck, Camila Chovet, Marc Lippert, Franck Kerhervé, Fethi Aloui

This paper presents an experimental study, based on the geometry of a cavity, about the flow effects using quantitative particle image velocimetry (PIV) and, local and instantaneous pressure measurements. Three configurations of rectangular deep cavities were investigated: symmetric and asymmetric...

Multi observer design for multicell converter

Abir Smati, Wassila Chagra, Denis Berdjag, Moufida Ksouri, Michael Defoort

This paper, discuss the observability of the multicellular converter which is classified as a switching hybrid system. Several observers will be used for the capacitors voltage estimation despite the partial observability of the system.

Some properties of range restricted GMRES methods

Mohammed Bellalij, Lothar Reichel, Hassane Sadok

The GMRES method is one of the most popular iterative schemes for the solution of large linear systems of equations with a square nonsingular matrix. GMRES-type methods also have been applied to the solution of linear discrete ill-posed problems. Computational experience indicates that for the...

Unknown input estimation for nonlinear descriptor systems via LMIs and Takagi-Sugeno models

Víctor Estrada Manzo, Zsofia Lendek, Thierry-Marie Guerra

This paper presents an unknown inputs observer for nonlinear descriptor systems. The approach uses the Takagi-Sugeno representation of the nonlinear model. In order to obtain strict linear matrix inequalities a novel observer structure is given. Thus the conditions can be efficiently solved via...

A bi-objective heuristic for heterogeneous MPSoC design space exploration.

Braham Lotfi Mediouni, Smail Niar, Rachid Benmansour, Karima Benatchba, Mouloud Koudil

Recent technology advances allow new generation reconfigurable-based embedded systems to contain a large number of cores and reconfigurable logic elements. Consequently, to take benefit of such very powerful hybrid reconfigurable MPSoC, designers need tools to explore the large design space of the...
