A robust method for MR image segmentation and multiple scleroses detection

H. Zouaoui, Abdelouahab Moussaoui, Mourad Oussalah, Abdelmalik Taleb-Ahmed

In the present article, we propose a new approach for the segmentation of the MR images of the Multiple Sclerosis (MS). The Magnetic Resonance Imaging (MRI) allows the visualization of the brain and it is widely used in the diagnosis and the follow-up of the patients suffering from MS. Aiming to...

Stability analysis of a class of switched nonlinear systems using the time scale theory

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai, Seddik Djouadi, Kevin Tomsovic

This paper investigates stability for a class of switched nonlinear systems evolving on a non-uniform time domain. The studied class of systems switch between a nonlinear continuous-time and a nonlinear discrete-time subsystem. This problem is formulated using time scale theory where the latter is...

Experimental characterization of the mechanical behaviour and the failure of multi-sheet and multi-material spot welded assembly

Rami Tounsi, Grégory Haugou, Fahmi Chaari, Nicolas Leconte, Eric Markiewicz

An experimental investigation of the mechanical behaviour of three-sheet multi-material spot welded assembly is performed. An experimental device based on the Arcan principle is developed to test the three-sheet spot welded specimen under pure opening mode, pure shear mode and mixed opening/shear...

Risk-taking, emotions and socio-cognitive dynamics of pedestrian street-crossing in the city

Stéphanie Coeugnet, Béatrice Cahour, Sami Kraïem

This study investigates pedestrian street-crossing decision-making to better appreciate both the complexity and the dynamics of this activity by analyzing the cognitive, emotional and social processes involved in such situations. We consider street-crossing decision-making in the context of...

The single-processor scheduling problem with time restrictions: complexity and related problems

Rachid Benmansour, Oliver Braun, Said Hanafi

We consider the single-processor scheduling problem with time restrictions (STR) in order to minimize the makespan, where a set of independent jobs has to be processed on a single processor, subject only to the following constraint: During any time period of length α, the number of jobs being...

A heterogeneous multi-core based biomedical application processing system and programming toolkit

Tassadaq Hussain, Amna Haider, Abdelmalik Taleb-Ahmed

Due to the growth of biological databases and biomedical instruments, the high performance active (real-time) signal processing becomes a challenge for medical scientists and engineers. The medical applications require a high-performance signal processor which can process the scientific and...

Repairnator patches programs automatically

Martin Monperrus, Simon Urli, Thomas Durieux, Matias Martinez, Benoit Baudry, Lionel Seinturier

Repairnator is a bot. It constantly monitors software bugs discovered during continuous integration of open-source software and tries to fix them automatically. If it succeeds in synthesizing a valid patch, Repairnator proposes the patch to the human developers, disguised under a fake human...

Influence of Surface Irregularities on Hydrodynamic Instabilities in Couette-Taylor Flow

Lamia Gaied, Marc Lippert, Laurent Keirsbulck, Maxence Bigerelle, Emna Berrich, Fethi Aloui

Abstract In this work, we propose an experimental study of roughness effect on hydrodynamic instabilities’ Couette-Taylor flow. During experiments, the inner cylinder rotates at a given angular velocity and the outer cylinder is maintained fix. The main objective of the study is to highlight the...

PIV and POD Investigations of Coherent Vortices Downstream Circular or Rectangular Obstacles Located Between Two Parallel Plates

Fethi Aloui, Amal Elawady, Khaled J Hammad

The study is an experimental investigations using PIV. The measurements were obtained by PIV for an unsteady laminar flow across a rectangular channel with a cross-section 300 × 30mm2, in the middle of which is located a cylindrical or a square obstacle. In the case of the cylindrical configuration...
