Quantitative analysis of galling in cold forging of a commercial Al-Mg-Si alloy

Kevin Le Mercier, Mirentxu Dubar, Katia Mocellin, André Dubois, Laurent Dubar

Multiple upsetting-sliding tests are performed at sliding velocities in the range of 20-200 mm.s-1 and at different plastic deformations to reproduce the local contact conditions experienced at the tool/workpiece interface during cold forging of a 6082 aluminium alloy. An original approach, able to...

Fast binary support vector machine learning method by samples reduction

Abdelhamid Djeffal, Chaouki Babahenini, Abdelmalik Taleb-Ahmed

Support vector machine is a well-known method of statistical learning by its good accuracy; however, its training time is very poor especially in case of huge databases. Many research works aim to reduce training samples to improve training time without significant loss in accuracy. In this paper,...

New use of the HITS algorithm for fast web page classification

Mohamed Nadjib Meadi, Chaouki Babahenini, Abdelmalik Taleb-Ahmed

The immense number of documents published on the web requires the utilization of automatic classifiers that allow organizing and obtaining information from these large resources. Typically, automatic web pages classifiers handle millions of web pages, tens of thousands of features, and hundreds of...

Calculation of greenhouse gas emissions of jatropha oil and jatropha biodiesel as alternative fuels for electricity production in Côte d’Ivoire

Atta Pascal Atta, Yao N'Guessan, Céline Morin, Anne Jaecker-Voirol, Georges Descombes

The electricity in Côte d’Ivoire is mainly produced from fossil energy sources. This causes damages on environment due to greenhouse gas emissions (GHG). The aim of this paper is to calculate the greenhouse gas (GHG) emissions of jatropha oil and jatropha biodiesel as alternative fuels for...

Iterative aggregation and disaggregation algorithm for pseudo-polynomial network flow models with side constraints

François Clautiaux, Said Hanafi, Rita Macedo, Marie-Emilie Voge, Cláudio Alves

This paper develops a general solution framework based on aggregation techniques to solve NP-Hard problems that can be formulated as a circulation model with specific side constraints. The size of the extended Mixed Integer Linear Programming formulation is generally pseudo-polynomial. To...

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...

Timetable Optimization during Railway Infrastructure Maintenance

Luis Diego Arenas Pimentel, Paola Pellegrini, Said Hanafi, Joaquin Rodriguez

Maintenance activities are necessary to maintain the functionality of the railway infrastructure. Commonly, timetables are elaborated by considering the infrastructure unavailability periods caused by the performance of maintenance activities. However, sometimes unplanned maintenance activities...

An efficient hybrid approach to the remote sensing land cover classification

Ehlem Zigh, B Kouninef, Rachid Nourine, Abdelmalik Taleb-Ahmed, Mohammed Kadiri

The support vector machine (SVM) is considered as one of the powerful algorithm in machine learning, so, it is has been widely used in remote sensing land cover classification field. However, this technique suffers from its sensitivity to the parameters setting and training set. For that, we...
