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...

An Improved Downlink MC-CDMA System for Eﬃcient Image Transmission

Mohammed Sofiane Bendelhoum, Ali Djebbari, Ismail Boukli Hacene, Abdelmalik Taleb-Ahmed

Image compression is an essential stage of the data archiving and transmitting process, as it reduces the number of bits and the time required to complete the transmission. In this article, a study of image transmission over the Multi-Carrier Code Division Multiple Access (MC-CDMA) downlink system...

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...

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...

A heuristic hybrid framework for vector job scheduling

Nareyus I Lawrance Amaldass, Cormac Lucas, Nenad Mladenovic

We examine the first phase of a known NP-hard 2-stage assembly problem. It consists of sequencing a set of jobs having multiple components to be processed. Each job has to be worked on independently on a specific machine. We consider these jobs to form a vector of tasks. Our objective is to...

Towards increased systems resilience: New challenges based on dissonance control for human reliability in Cyber-Physical&Human Systems

Frédéric Vanderhaegen

This paper discusses concepts and tools for joint human and cyber-physical-systems analysis and control in the view of increasing the whole system resilience. More precisely, it details new challenges for human reliability based on dissonance control of Cyber-Physical&Human Systems (CPHS) to...

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...

A view of trust and information system security under the perspective of critical infrastructure protection, Une vision de la recherche sur la confiance et la sûreté des systèmes d’information dans le cadre de la protection des infrastructures critiques

Bako Rajaonah

Although trust is recognized as important in security issues of computer networking environments, few studies on information systems deal with both trust and security, and those existing tend to remain within the short perimeter of two-agent interactions. We propose to rethink trust research on..., Bien que la confiance soit reconnue comme importante dans les environnements numériques, peu d'études sur les systèmes d'information traitent à la fois de leur sûreté et de la confiance. Celles qui existent tendent à rester dans le périmètre étroit des interactions entre deux agents. Nous...

Experimental Spectroscopic Studies of Carbon Monoxide (CO) Fluorescence at High Temperatures and Pressures, Etudes experimentales de spectroscopie de fluorescence du monoxyde de carbone (CO) à hautes températures et pressions

Olivier Carrivain, Mikael Orain, Nelly Dorval, Céline Morin, Guillaume Legros

Two-photon excitation laser-induced fluorescence of carbon monoxide (CO-LIF) is investigated experimentally in order to determine the applicability of this technique for imaging CO concentration in aeronautical combustors. Experiments are carried out in a high temperature, high-pressure test cell,..., Une étude expérimentale de spectroscopie LIF à deux photons de la molécule CO (CO-LIF) est menée afin d'évaluer sa faisabilité en mode imagerie dans des moteurs aéronautiques. Les expériences sont réalisées d'une part dans une cellule à hautes température et pression et dans une flamme de...
