Variable neighborhood search for location routing

Bassem Jarboui, Houda Derbel, Said Hanafi, Nenad Mladenovic

In this paper we propose various neighborhood search heuristics (VNS) for solving the location routing problem with multiple capacitated depots and one uncapacitated vehicle per depot. The objective is to find depot locations and to design least cost routes for vehicles. We integrate a variable…

Energetic optimization of the performances of a hot air engine for micro-CHP systems working with a Joule or an Ericsson cycle

Marie Creyx, Eric Delacourt, Céline Morin, Bernard Desmet, Philippe Peultier

The micro combined heat and electrical power systems (micro-CHP) with hot air engines are well adapted for solid biomass upgrading, in particular, the Ericsson engines working with an open cycle and an external combustion. This paper presents a model of an Ericsson engine with a compression and an…

A three-dimensional study of electronic component cooling using a flat heat pipe

Hamdy Hassan, Souad Harmand

In this article, a three-dimensional thermal and hydrodynamic numerical model using a flat heat pipe (vapor chamber) is proposed for cooling of electronic components. The heat pipe is composed of a vapor region sandwiched between two wick regions, which are covered by two flat copper plates. A…

Plastic deformation of structural steels under hot-working conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Damien Barbier, Mirentxu Dubar, Jacky Lesage

The present study has been conducted in order to formulate a rational description of the flow stress of structural steels, when these are deformed in tension under hot-working conditions. The simplified formulation that has been developed only involves the analysis of the positive work-hardening…

Unified Driver Model simulation and its application to the automotive, rail and maritime domains

Pietro Carlo Cacciabue, Simon Enjalbert, Håkan Söderberg, Andreas Tapani

This paper describes the implementation of a model of a driver into a computerised numerical simulation. The model is developed to capture the essential characteristics and common aspects of cognition and behaviour of a human being in control of a “vehicle” in different surface transport systems,…

A comprehensive blank development method for forming sheet metal parts

Jianjun Wu, Xin Wu, Liangcai Deng, Hakim Naceur

For some shortcomings in the use of standard radial length development in the blank development for forming sheet metal parts, an improved radial length normal spreading approach considering outside normal direction is developed to resolve blank development in sheet metal forming. Moreover, a…

Armouring solutions against high velocity impact using 2D laminates and 3D warp interlock composites

Benjamin Provost, François Boussu, Daniel Coutellier, Daniel Vallée, Fabien Rondot, Julien Nussbaum

Since the emergence of the first armoured vehicles on battlefields, armour shield was mainly centred on conventional metallic materials, widespread solutions nowadays. For a long time, weight reduction in armoured protection, which represents the largest part of the vehicle’s overall weight, has…

Investigation of the performance of modified TCM scheme for the protection of SPIHT-based compressed images over fading channel

Mohamed Ben Aissa, Abdesselam Bassou, Mohammed Beladgham, Abdelmalik Taleb-Ahmed, Abdelmounaim Moulay Lakhdar

In this paper, a new variant of trellis-coded modulation with Ungerboeck-Gray mapping 'TCM-UGM' is presented for spectral efficiency of 2 bit/s/Hz. The performance of this encoding scheme is investigated over Rayleigh fading channel. The simulation result, using 16-state TCM-UGM encoder,…

Assessment of ship maneuverability by using a coupling between a nonlinear transient ship maneuvering model and mathematical programming techniques

T. Tran Khanh, Abdellatif Ouahsine, Hakim Naceur, Karima El Wassifi

In this paper, a numerical method based on a coupling between a mathematical model of nonlinear transient ship manoeuvring motion in the horizontal plane and Mathematical Programming (MP) techniques is proposed. The aim of the proposed procedure is an efficient estimation of optimal ship…

Liquid hydrocarbon fuels from fish oil industrial residues by catalytic cracking

Nadia Mrad, Maria Paraschiv, Fethi Aloui, Edwin Geo Varuvel, Mohand Tazerout, Sassi Ben Nasrallah

In the present work, catalytic cracking of fish oil industrial residue was investigated to study the effect of temperature, type of catalyst and the heating rate on the yield of organic liquid fraction (OLF) and its acid value. The highest bio-oil yield of 72% (wt.) was obtained at temperature…
