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…

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…

ELECTRE I Based Relevance Decision-Makers Feedback to the Location Selection of Distribution Centers

Maroi Agrebi, Mourad Abed, Moahamed Nazih Omri

The location selection of distribution centers is one of the important strategies to optimize the logistics system. To solve this problem, under certain environment, this paper presents a new multicriteria decision-making method based on ELECTRE I. The proposed method helps decision-makers to…

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…

A Graphical Model Based on Performance Shaping Factors for Assessing Human Reliability

Subeer Rangra, Mohamed Sallak, Walter Schön, Frédéric Vanderhaegen

Human reliability assessment (HRA) is an aspect of risk analysis concerned with identifying, analyzing, and quantifying the causes, contributions, and occurrence of human failures. Applications of existing HRA methods are often domain-specific, and difficult to implement even for experts. Also, due…

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…

A review of characterisation and parameters identification of materials constitutive and damage models: From normalised direct approach to most advanced inverse problem resolution

Eric Markiewicz, Bertrand Langrand, Delphine Notta-Cuvier

The paper aims at providing an overview of the research activities performed in the two past decades in the field of materials characterisation under dynamic loadings (i.e. from to for structural crashworthiness and impact applications) and identification of parameters of constitutive behaviour and…

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…

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…
