A rule-based support system for dissonance discovery and control applied to car driving

Frédéric Vanderhaegen

This paper is based on the concept of dissonance, that is, gaps or conflicts existing in a specific knowledge base or among different knowledge bases. It presents a rule-based system that assists human operators in dissonance discovery and control by taking into account two kinds of dissonance, i.e…

Standardized Usability Questionnaires: Features and Quality Focus

Ahlem Assila, Káthia Marçal de Oliveira, Houcine Ezzedine

For the last few decades more than twenty standardized usability questionnaires for evaluating software systems have been proposed. These instruments have been widely used in the assessment of usability of user interfaces. They have their own characteristics, can be generic or address specific…

Discrete sensors distribution for accurate plantar pressure analyses

Laetitia Claverie, Anne Ille, Pierre Moretto

The aim of this study was to determine the distribution of discrete sensors under the footprint for accurate plantar pressure analyses. For this purpose, two different sensor layouts have been tested and compared, to determine which was the most accurate to monitor plantar pressure with wireless…

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…

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 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…

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.…
