A heuristic hybrid framework for vector job scheduling

Nareyus I Lawrance Amaldass, Cormac Lucas, Nenad Mladenovic

We examine the first phase of a known NP-hard 2-stage assembly problem. It consists of sequencing a set of jobs having multiple components to be processed. Each job has to be worked on independently on a specific machine. We consider these jobs to form a vector of tasks. Our objective is to…

Asymptotically necessary and sufficient conditions for Takagi–Sugeno models using generalized non-quadratic parameter-dependent controller design

Raymundo Márquez Borbόn, Thierry-Marie Guerra, Miguel Bernal, Alexandre Kruszewski

Results in this paper generalize recent approaches on non-quadratic controller design for Takagi–Sugeno models based on a matrix transformation. Conditions thus obtained depend on a single parameter which allows an efficient search of feasible solutions via linear matrix inequalities; moreover,…

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…

Refinements of some Pachpatte and Bihari inequalities on time scales

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

In this study, some generalizations and refinements of some inequalities of Pachpatte and Bellman-Bihari types are established on arbitrary time domains using the time scale theory. The obtained results unify continuous and discrete inequalities and extend some results known in the literature. The…

Towards increased systems resilience: New challenges based on dissonance control for human reliability in Cyber-Physical&Human Systems

Frédéric Vanderhaegen

This paper discusses concepts and tools for joint human and cyber-physical-systems analysis and control in the view of increasing the whole system resilience. More precisely, it details new challenges for human reliability based on dissonance control of Cyber-Physical&Human Systems (CPHS) to…

Design exploration of efficient implementation on SoC heterogeneous platform: HEVC intra prediction application

Manel Kammoun, Ahmed Ben Atitallah, Rabie Ben Atitallah, Nouri Masmoudi

The relationship between CPU and hardware accelerator is critical especially in some systems that require intensive tasks and large amount of data to deal with such as video coding systems. This cooperation provides significant improvements in run-time speed and power consumption. As software (SW)…

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…

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.…

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…
