Variable and single neighbourhood diving for MIP feasibility

Jasmina Lazic, Raca Todosijević, Said Hanafi, Nenad Mladenovic

In this paper, we propose two new diving heuristics for finding a feasible solution for a mixed integer programming problem, called variable neighbourhood (VN) diving and single neighbourhood (SN) diving, respectively. They perform systematic hard variable fixing (i.e. diving) by exploiting the…

Context Aware Criteria for the Evaluation of Mobile Decision Support Systems

Emna Ben Ayed, Mounir Ben Ayed, Christophe Kolski, Houcine Ezzedine, Faiez Gargouri

The propagation and convergence of wireless communications, Internet, and mobile technology has given rise to new generation of decision support utilities commonly known as Mobile Decision Support Systems. Drawing on technology acceptance and decision-making theories, this study explores critical…

Scavenging Process Analysis in a 2-Stroke Engine by CFD Approach for a Parametric 0D Model Development

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

This paper presents a method to improve cylinder design of 2-stroke auto-ignition engine based on a CFD (Computational Fluid Dynamics) study of internal flows in the chamber and an unsteady global 0D parametric approach. In 2-stroke engine, scavenging process plays an important role regarding…

Dynamic recrystallization of spheroidal graphite iron during hot cutting operations.

Kevin Le Mercier, Michel Watremez, Laurence Fouilland-Paille, Laurent Dubar

The objective of the present paper is to analyse the dynamic recrystallization process occurring during the hot cutting of spheroidal graphite iron. In the first instance, hot cutting tests are performed with an orthogonal cutting test bench. The emergence of dynamic recrystallization is…

Measurements of liquid film thickness of a wide horizontal co-current stratified air-water flow

François Touron, Larbi Labraga, Laurent Keirsbulck, Hervé Bratec

A horizontal co-current stratified two-phase flow was studied in a duct with a rectangular section. Its dimensions were such that the top and side walls did not influence the interfacial waves. The film thickness was almost of the millimeter. The Reynolds number based on the mean height and…
