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,…

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…

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…

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…

New complexity results on scheduling problem in a robotic cell

Nacira Chikhi, Moncef Abbas, Rachid Benmansour, Said Hanafi

This paper explores the coordinated scheduling problem between production and transportation in a two stage flow shop with dedicated machines. There are two dedicated machines at the first stage and one common machine at the second stage. Each job has to be processed on a specified machine at the…

A co-opetitive framework for the hub location problems in transportation networks

Rahimeh Neamatian Monemi, Shahin Gelareh, Said Hanafi, Nelson Maculan

In this paper, we present the first model of co-opetition for a Hub Location Problem between two logistics service provider (LSPs) companies where the mother company is the owner of infrastructure. The LSPs would like to cooperate with each other by establishing joint edges with limited capacities…

AS8‐static random access memory (SRAM): asymmetric SRAM architecture for soft error hardening enhancement

Ihsen Alouani, Mahmoud Elsharkasy Wael, Ahmed Eltawil, Fadi Kurdahi, Smail Niar

Soft errors in semiconductor memories occur due to charged particle strikes on sensitive nodes. Technology and voltage scaling increased dramatically the susceptibility of static random access memories (SRAMs) to soft errors. In this study, the authors present AS8-SRAM, a new asymmetric memory cell…
