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…

A basic variable neighborhood search heuristic for the uncapacitated multiple allocation p-hub center problem

Jack Brimberg, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

The uncapacitated multiple allocation p-hub center problem (UMApHCP) consists of choosing p hub locations from a set of nodes with pairwise traffic demands in order to route the traffic between the origin-destination pairs such that the maximum cost between origin-destination pairs is minimum. It…

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…

Output Feedback Active Suspension Control With Higher Order Terminal Sliding Mode

Jagat Jyoti Rath, Michael Defoort, Hamid Reza Karimi, Kalyana Chakravarthy Veluvolu

The control of an automotive suspension system using hydraulic actuators is a highly complex nonlinear control task dealing with system nonlinearities, external disturbances, and uncertainties. In this work, an output feedback active suspension control scheme is proposed to achieve a ride comfort…

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…
