Passive control of deep cavity shear layer flow at subsonic speed

Mouhammad El Hassan, Laurent Keirsbulck

Passive control of the flow over a deep cavity at low subsonic velocity is considered in the present paper. The cavity length-to-depth aspect ratio is L/H = 0.2. particle image velocimetry (PIV) measurements characterized the flow over the cavity and show the influence of the control method on the…, Nous prenons ici en considération le contrôle passif d’un écoulement à faible vitesse subsonique sur une cavité. Le rapport longueur à profondeur de la cavité est L/H = 0.2. Les mesures de vélocimétrie par image de particule caractérisent l’écoulement au dessus de la cavité et montrent l’influence…

Modeling and PDC fuzzy control of planar parallel robot: A differential– algebraic equations approach

Benyamine Allouche, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

Many works in the literature have studied the kinematical and dynamical issues of parallel robots. But it is still difficult to extend the vast control strategies to parallel mechanisms due to the complexity of the model-based control. This complexity is mainly caused by the presence of multiple…

Evaluating Resiliency of Supply Chain Network: A Data Envelopment Analysis Approach

Pourya Pourhejazy, Oh-Kyoung Kwon, Young-Tae Chang, Hyosoo Park

Supply chains can be vulnerable to sudden disruptions, especially when it emphasizes efficient operation. In this regard, supply chain resilience (SCR) has received attention recently to cope with disruptions and improve competitiveness. This paper presents a novel methodology to measure resilience…

β-NTF reduction and fast kriging simulation of optimal engine configurations

Stéphanie Cagin, Xavier Fischer, Eric Delacourt, Nachida Bourabaa, Céline Morin, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

In an optimization process, models are applied to simulate different design behaviors in order to determine the most suitable one. However, this requires the use of a structured methodology to correctly explore the design space and truly converge to the best solution. It is therefore necessary to…

Research directions for integrating the triple bottom line in maintenance dashboards

Olivier Sénéchal

Among the activities managed by an organization, the maintenance of the resources it uses considerably affects sustainable performance. In this paper, we propose research on decision support for controlling sustainable performance induced by maintenance processes based on the core principles of…

Novel semi-blind estimation for turbo decoding in impulsive noise channel

Ali Chemsa, Djamel Saigaa, Hatem Ghodbane, Abdelmalik Taleb-Ahmed

In order to calculate the branches metric in the maximum a posteriori algorithm of turbo decoder, it is mandatory to know the values of parameters of the noise contaminating the transmitted signal. In the case of a generalized Gaussian distribution impulsive noise, it is very difficult to estimate…

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…

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…

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…

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…
