Adaptive Medical Image Compression Based on Lossy and Lossless Embedded Zerotree Methods

Sid Ahmed Elhannachi, Nacéra Benamrane, Abdelmalik Taleb-Ahmed

Since the progress of digital medical imaging techniques, it has been needed to compress the variety of medical images. In medical imaging, reversible compression of image's region of interest (ROI) which is diagnostically relevant is considered essential. Then, improving the global...

Macro-modeling of spot weld strength and failure: Formulation and identification procedure based on pure and mixed modes of loading, Modélisation à l'échelle macroscopique de la tenue et de la rupture des points soudés : formulation et procédure d'identification fondée sur des changements en mode purs et mixtes

Rim Chtourou, Nicolas Leconte, Bassem Zouari, Fahmi Chaari, Eric Markiewicz, Bertrand Langrand

Purpose This paper aims to propose a macro modeling approach to simulate the mechanical behavior and the failure of spot welded joints in structural crashworthiness computations. Design/methodology/approach A connector element is proposed to simulate the behavior and failure of spot weld joints. An...

Urban legends in gait analysis

Paul Allard, Sebastien Leteneur, Eric Watelain, Mickaël Begon

Impaired gait patterns are often compared to that of a group of able-bodied subjects. This latter group usually forms a gold standard. Variability in able-bodied gait parameters could reflect different normal locomotion patterns. Furthermore, a lack of statistical difference between patient data...

Reducing the Toxicity Risk in Antibiotic Prescriptions by Combining Ontologies with a Multiple Criteria Decision Model

Souhir Ben Souissi, Mourad Abed, Lahcen Elhiki, Philippe Fortemps, Marc Pirlot

We consider the risk of adverse drug events caused by antibiotic prescriptions. Antibiotics are the second most common cause of drug related adverse events and one of the most common classes of drugs associated with medical malpractice claims. To cope with this serious issue, physicians rely on...

Refinements of some Pachpatte and Bihari inequalities on time scales

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

In this study, some generalizations and refinements of some inequalities of Pachpatte and Bellman-Bihari types are established on arbitrary time domains using the time scale theory. The obtained results unify continuous and discrete inequalities and extend some results known in the literature. The...

Mock-up Study of the Effect of Wall distance on the Thermal Rating of Power Cables in Ventilated Tunnels

Fahd Boukrouche, Christophe Moreau, Julien Pellé, François Beaubert, Souad Harmand, Olivier Moreau

Power transmission through power cables installed in ventilated tunnels is increasingly used worldwide and offers a complex thermal environment. Established correlations currently in use have been deduced from a nonfully developed turbulent flow and the effect of the proximity to a tunnel wall is...

Effect of Operating Parameters on the Heat Transfer and Liquid Film Thickness of Revolving Heat Pipe

Hamdy Hassan, Souad Harmand

This paper presents a study on the effects of operating parameters on the liquid film thickness and heat transfer of revolving heat pipe. The effects of speed, radius of rotation, evaporator and condenser temperatures, and mass of the working fluid are considered. Also, the effects of these...

Quantitative analysis of galling in cold forging of a commercial Al-Mg-Si alloy

Kevin Le Mercier, Mirentxu Dubar, Katia Mocellin, André Dubois, Laurent Dubar

Multiple upsetting-sliding tests are performed at sliding velocities in the range of 20-200 mm.s-1 and at different plastic deformations to reproduce the local contact conditions experienced at the tool/workpiece interface during cold forging of a 6082 aluminium alloy. An original approach, able to...
