One-level reformulation of the bi-level Knapsack problem using dynamic programming

Luce Brotcorne, Said Hanafi, Raïd Mansi

In this paper, we consider the Bilevel Knapsack Problem (BKP), which is a hierarchical optimization problem in which the feasible set is determined by the set of optimal solutions for a parametric Knapsack Problem. We introduce a new reformulation of the BKP into a one-level integer programming…

Large-Eddy simulation of turbulent heat transfer in pipe flows with respect to Reynolds and Prandtl number effects.

Meryem Ould-Rouiss, M. Bousbai, A. Mazouz

Heat transfer in a fully developed turbulent pipe flow is investigated by use of the large eddy simulation technique. Isoflux condition is imposed at the wall. Four Prandtl numbers are considered (0.71,3,5,7) and three Reynolds numbers (5500, 10000, 20000). The effects of Reynolds and Prandtl…

Understanding soft evidence as probabilistic evidence : illustration with several use cases

Ali Ben Mrad, Véronique Delcroix, Sylvain Piechowiak, Mohamed-Amine Maalej, Mohamed Abid

This paper aims to get a better understanding of the notions of evidence, probabilistic evidence and likelihood evidence in Bayesian Networks. Evidence comes from an observation of one or several variables. Soft evidence is probabilistic evidence, since the observation consists in a local…

Natural convection heat transfer of nanofluids along a vertical plate embedded in porous medium

Ziya Uddin, Souad Harmand

The unsteady natural convection heat transfer of nanofluid along a vertical plate embedded in porous medium is investigated. The Darcy-Forchheimer model is used to formulate the problem. Thermal conductivity and viscosity models based on a wide range of experimental data of nanofluids and…

Modeling and characterization of bonded joints at high strain rates, Modélisation et caractérisation des joints collés à hautes vitesses de déformation

Benjamin Bourel, Grégory Haugou, Franck Lauro, Raphaël Deltombe, Denis Lesueur, Bruno Bennani

This paper deals with the modeling of bonded joints for structures subjected to dynamic crash loading. This new model based on a cohesive element takes into account the viscoelastic behavior, the damage and the failure of the adhesive. Due to the strain rate sensitivity, the identification of…, Ce papier traite de la modélisation de joints collés pour les structures soumises à des sollicitations de type crash. Cette nouvelle modélisation basée sur un élément cohésif tient compte du comportement viscoplastique, de l'endommagement ainsi que de la rupture de l'adhésive. Sensible à…

Robustness study and reliability growth based on exploratory design of experiments and statistical analysis: a case study using a train door test bench

Laurent Cauffriez, Pierre Loslever, Nathalie Caouder, Fabien Turgis, Reynald Copin

This paper presents a methodology to improve the reliability/robustness of a complex mechatronic system for passenger access, which is greatly stressed over its life cycle. The proposed methodology aims to weed out design problems during the development phase and to test the robustness of the…

Inducing Swirling Flow in Heat Exchanger Pipes for Reduced Fouling Rate

Halldor Pálsson, François Beaubert, Sylvain Lalot

Fouling buildup in circular heat exchanger pipes is a common problem in the industry. Various methods have been proposed to increase the shear stress of the fluid near the pipe wall. This is known to reduce fouling rate, as well as increasing the heat transfer rate of heat exchangers. In this…

The impact of facial emotional expressions and sex on interpersonal distancing as evaluated in a computerized stop-distance task.

Holly Miller, Anne-Sophie Chabriac, Mikael Molet

This study utilizes a novel computerized stop-distance task to examine social space preferences of young adult female and male participants (18-23 years old) who envisioned being approached by others of both sexes who were displaying different facial emotional expressions. The results showed that…

Onset of atomization on horizontal, shear-driven liquid films at the vicinity of a sharp corner

Evangelos Bacharoudis, Hervé Bratec, Laurent Keirsbulck, Jean-Marie Buchlin, Larbi Labraga

In many engineering applications, the liquid films have to deal with sudden changes of the wall geometries in which they flow over. The present work concerns the study of the onset of the film atomization in corner geometries. Specifically, films with thickness in the range of 1 mm < hf < 2.5…
