Scheduling with sequence-dependent setup times and periodic maintenance on a single machine to minimize the total weighted completion time

Hanane Krim, Rachid Benmansour, David Duvivier

In this work, the objective is to compute a schedule that minimizes the weighted completion times, subject to sequence-dependent setup time and periodic maintenance. To the best of our knowledge, only few works report studies on scheduling problems considering both sequence-dependent setup times...

Modélisation du transfert thermique des câbles en galerie, Heat transfer modeling of power cables in tunnels

Fahd Boukrouche

Une analyse critique de la modélisation des échanges thermiques des câbles d’énergie en galerie est réalisée, avec l’étude de facteurs d’influences propres aux modes de pose des câbles dans ces ouvrages. Les câbles, de plusieurs kilomètres, chauffent du fait du courant transmis dans leurs âmes. Ils..., A critical analysis of the thermal rating of power cables in tunnels is carried out, with the study of factors of influence specific to cable laying constrains. The heat generation in the cables, due to the transiting current, is dissipated by an axial turbulent forced convection and by radiation...

Stratégie numérique et expérimentale pour la maîtrise des dégradations des outillages en mise en forme à froid, Experimental and numerical strategy for the evaluation of the degradations mechanisms of cold forging tools

Kevin Le Mercier

La mise en forme à froid des alliages d’aluminium peut être limitée par les transferts de matière sur la surface des outillages pouvant mener au grippage. L’objectif de ce travail de thèse est de contribuer à une meilleure compréhension de ces mécanismes pour permettre à terme d’optimiser les..., Cold forming of aluminium alloys can be limited by a severe material transfer to the die surfaces, compromising the process viability. The purpose of this research work is to contribute to a broader understanding of the galling mechanisms which would further allow the optimisation of the forming...

Simplified Log - Likelihood Ratio Calculation for Binary LDPC Codes

Latifa Mostari, Abdelmalik Taleb-Ahmed

Combining binary LDPC codes and high order constellations is a simple but effective way to improve the bandwidth efficiency. Since the binary LDPC codes require soft decisions as the input information, the constellation has to provide soft information calculated by Log-Likelihood Ratio (LLR) to it...

Variable neighborhood search variants for Min-power symmetric connectivity problem

A.I. Erzin, Nenad Mladenovic, R.V. Plotnikov

We consider the problem of optimal communication tree construction in a given undirected weighted graph. Such a problem occurs while minimizing the power consumption of data transmission in different distributed networks in the case when network elements are able to adjust their transmission ranges...

J-means and I-means for minimum sum-of-squares clustering on networks

Alexey Nikolaev, Nenad Mladenovic, Raca Todosijević

Given a graph, the Edge minimum sum-of-squares clustering problem requires finding p prototypes (cluster centres) by minimizing the sum of their squared distances from a set of vertices to their nearest prototype, where a prototype can be either a vertex or an inner point of an edge. In this paper...

A global strategy for the stability analysis of friction induced vibration problem with parameter variations

Hai Quan Do, Franck Massa, Thierry Tison, Bertrand Lallemand

This paper presents a numerical strategy to reanalyze the modified frequency stability analysis of friction induced vibration problem. The stability analysis of a mechanical system relies on several coupling steps, namely a non-linear static analysis followed by linear and complex eigenvalue...
