Experimental assessment of the sudden-reversal of the oxygen dilution effect on soot production in coflow ethylene flames

Qianlong Wang, Guillaume Legros, Jérôme Bonnety, Céline Morin, Alexis Matynia, Jean-Louis Consalvi, Fengshan Liu

This paper explores the influence of oxygen dilution on soot production when oxygen is added to the fuel stream of a steady laminar ethylene flame established over the Santoro axisymmetric coflow burner. Interestingly, at an oxygen mole fraction X_{ax}^{O_2,trans} located between 30% and 32%, a...

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...

Nopol: Automatic Repair of Conditional Statement Bugs in Java Programs

Jifeng Xuan, Matias Martinez, Favio Demarco, Maxime Clément, Sebastian Lamelas, Thomas Durieux, Daniel Le Berre, Martin Monperrus

We propose NOPOL, an approach to automatic repair of buggy conditional statements (i.e., if-then-else statements). This approach takes a buggy program as well as a test suite as input and generates a patch with a conditional expression as output. The test suite is required to contain passing test...

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...

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...

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...

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...

Experimental study of the cooling performance of phase change material with discrete heat sources – Continuous and intermittent regimes

Salma Gharbi, Souad Harmand, Sadok Ben Jabrallah

This paper presents an experimental investigation of phase change material (PCM, Plastic paraffin) behavior in a rectangular enclosure with three discrete heat sources flush-mounted on the right vertical wall. The remaining walls of the cavity are adiabatic. Maximizing the critical time (time...
