Hybrid Self-Adaptive Evolution Strategies Guided by Neighborhood Structures for Combinatorial Optimization Problems

Vitor N. Coelho, Igor M. Coelho, Marcone J.F. Souza, Thays A. Oliveira, Luciano Perdigão Cota, Matheus Nohra Haddad, Nenad Mladenovic, Rodrigo Pedrosa Silva, Frederico G. Guimarães

This article presents an Evolution Strategy (ES)--based algorithm, designed to self-adapt its mutation operators, guiding the search into the solution space using a Self-Adaptive Reduced Variable Neighborhood Search procedure. In view of the specific local search operators for each individual, the...

A switching mechanism framework for optimal coupling of predictive scheduling and reactive control in manufacturing hybrid control architectures

José-Fernando Jimenez Gordillo, Abdelghani Bekrar, Damien Trentesaux, Paulo Leitão

Nowadays, manufacturing systems are seeking control architectures that offer efficient production performance and reactivity to disruptive events. Dynamic hybrid control architectures are a promising approach as they are not only able to switch dynamically between hierarchical, heterarchical and...

New MPPT algorithm for PV applications based on hybrid dynamical approach

Shahrazed Elmetennani, Taous-Meriem Laleg-Kirati, Mohamed Djemai, Mohamed Tadjine

This paper proposes a new Maximum Power Point Tracking (MPPT) algorithm for photovoltaic applications using the multicellular converter as a stage of power adaptation. The proposed MPPT technique has been designed using a hybrid dynamical approach to model the photovoltaic generator. The hybrid...

Electrochemical Measurements for Real-Time Stochastic Reconstruction of Large-Scale Dynamics of a Separated Flow

Fawzi Fadla, Anthony Graziani, Franck Kerhervé, Romain Mathis, Marc Lippert, David Uystepruyst, Laurent Keirsbulck

The ability of electrochemical sensors to properly measure wall shear stress is here considered for using these sensors as potential candidates for time-resolved estimation of the large-scale activity occurring in the flow separation region downstream of a bump. The inflow Reynolds number...

A methodology for the viscoplastic behaviour characterisation of spot-weld heat affected materials

Eric Markiewicz, Bertrand Langrand, Nicolas Leconte, Jacky Fabis, Thomas Dupuy

The material behaviour of all zones of a spot-welded assembly needs to be known to build the finite element (FE) model of its fast dynamics strength. A methodology employing a thermomechanical simulator is thus proposed to replicate the micro-structure of different HAZ materials in a spot-weld. The...

On the vortex dynamics of shear-driven deep cavity flows with asymmetrical walls

Denis Cornu, Laurent Keirsbulck, Franck Kerhervé, Fethi Aloui, Marc Lippert

The influence of the length-to-depth aspect ratio and of wall asymmetry on the main vortical flow structures evolving in rectangular two-dimensional deep cavities is studied experimentally using wall-pressure and particle image velocimetry (PIV) measurements. Wall-pressure and cavity flow..., En utilisant des mesures de la pression du mur et de PIV, nous étudions expérimentalement l’influence du rapport de forme longueur versus profondeur et de l’asymétrie du mur sur la structure d’écoulement tourbillonnant principal évoluant dans des cavités profondes à deux dimensions rectangulaires....

Anatomie descriptive, radiographique, topographique et fonctionnelle appliquée aux fractures de l’extrémité distale du radius, Descriptive, radiographic, topographic and functional anatomy applied to distal radius fractures

Christian Fontaine, Régis Bry, Pascale Laronde, Elvire Guerre, Aurélien Aumar

Une connaissance précise de l’anatomie est nécessaire à la bonne prise en charge des fractures de l’extrémité distale du radius (EDR) : connaissance de l’ostéologie normale et pathologique de l’EDR, des articulations radio-ulnaire distale et radiocarpienne, tant sur le plan descriptif que..., Extensive anatomical knowledge is needed in order to correctly treat distal radius fractures: normal and pathological osteology of the distal radius, distal radio-ulnar joint and radiocarpal joint—both on the descriptive and functional level—the neurovascular and muscular environments of the distal...

Interaction Tangible sur Table, définitions et modèles, Tangible interaction on tabletop, definitions and models

Sophie Lepreux, Julien Castet, Nadine Couture, Emmanuel Dubois, Christophe Kolski, Sébastien Kubicki, Valérie Maquil, Guillaume Riviere

Depuis quelques années les interfaces tangibles impliquant des interactions réalisées via un objet (ou plusieurs) prennent de plus en plus d’importance dans les recherches en interaction homme-machine. L’objet tangible représente un sujet ou une action ; l’objet agit sur le système, telle une..., In recent years, tangible user interfaces, which imply interactions performed with one or several objects, gain more and more interest in research in Human-Computer Interaction (HCI). The tangible object represents a subject or an action. It acts on the system, as an action in classical user...

The influence of shoe drop on the kinematics and kinetics of children tennis players

Alexis Herbaut, Pascale Chavet, Maxime Roux, Nils Guéguen, Christophe Gillet, Franck Barbier, Emilie Simoneau-Buessinger

This study investigated the immediate effects of reducing the shoe drop (i.e. the difference between the heel and the forefoot height) on the kinematics and kinetics of the lower extremities of children tennis players performing a tennis-specific movement. Thirteen children tennis players performed...

An adaptive perturbation-based heuristic: An application to the continuous p-centre problem

Abdalla Elshaikh, Said Salhi, Jack Brimberg, Nenad Mladenovic, Becky Callaghan, Gábor Nagy

A self-adaptive heuristic that incorporates a variable level of perturbation, a novel local search and a learning mechanism is proposed to solve the p-centre problem in the continuous space. Empirical results, using several large TSP-Lib data sets, some with over 1300 customers with various values...
