Modeling and PDC fuzzy control of planar parallel robot: A differential– algebraic equations approach

Benyamine Allouche, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

Many works in the literature have studied the kinematical and dynamical issues of parallel robots. But it is still difficult to extend the vast control strategies to parallel mechanisms due to the complexity of the model-based control. This complexity is mainly caused by the presence of multiple…

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…

Iterative aggregation and disaggregation algorithm for pseudo-polynomial network flow models with side constraints

François Clautiaux, Said Hanafi, Rita Macedo, Marie-Emilie Voge, Cláudio Alves

This paper develops a general solution framework based on aggregation techniques to solve NP-Hard problems that can be formulated as a circulation model with specific side constraints. The size of the extended Mixed Integer Linear Programming formulation is generally pseudo-polynomial. To…

Passive control of deep cavity shear layer flow at subsonic speed

Mouhammad El Hassan, Laurent Keirsbulck

Passive control of the flow over a deep cavity at low subsonic velocity is considered in the present paper. The cavity length-to-depth aspect ratio is L/H = 0.2. particle image velocimetry (PIV) measurements characterized the flow over the cavity and show the influence of the control method on the…, Nous prenons ici en considération le contrôle passif d’un écoulement à faible vitesse subsonique sur une cavité. Le rapport longueur à profondeur de la cavité est L/H = 0.2. Les mesures de vélocimétrie par image de particule caractérisent l’écoulement au dessus de la cavité et montrent l’influence…

Automatic Repair of Real Bugs in Java: A Large-Scale Experiment on the Defects4J Dataset

Matias Martinez, Thomas Durieux, Romain Sommerard, Jifeng Xuan, Martin Monperrus

Defects4J is a large, peer-reviewed, structured dataset of real-world Java bugs. Each bug in Defects4J comes with a test suite and at least one failing test case that triggers the bug. In this paper, we report on an experiment to explore the effectiveness of automatic test-suite based repair on…

Shoe drop reduction influences the lower limb biomechanics of children tennis players during an open stance forehand: A longitudinal study

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

Compared to traditional tennis shoes, using 0-drop shoes was shown to induce an immediate switch from rear- to forefoot strike pattern to perform an open stance tennis forehand for 30% of children tennis players. The purpose of the study was to examine the long-term effects of a gradual reduction…

Investigation of turbulent slot impinging jet using laser doppler anemometry method–Experimental research and error analysis

Mahmoud Charmiyan, Ahmed-Reza Azimian, Ebrahim Shirani, Fethi Aloui

In this paper, the results obtained from experimental measurements of average and turbulence quantities of a turbulent rectangular impinging jet hitting a fixed wall is reported using the laser doppler anemometry (LDA) method. The nozzle to plate distance is 10 times the nozzle width, and the tests…

Etude des instabilités d'un écoulement décollé induit par une bosse

Fawzi Fadla, Ayoub Bouanik, Laurent Keirsbulck

L'objectif de ce travail est d'améliorer notre compréhensions sur la dynamique du décollement en vue de définir les paramètres clés dans le but de concevoir un modèle simplifié et prédictif de décollement en échange du modèle classique stationnaire et bidimensionnel. Ce travail sera…

Etudes expérimentales et numériques d'un jet de particules : application au freinage ferroviaire

Charlène Octau, Marc Lippert, Talib Dbouk, Michel Watremez, Laurent Keirsbulck, Laurent Dubar

Les transports ferrés urbains, bien que considérés comme une alternative écologique au transport individuel, font aujourd'hui l'objet d'un intérêt grandissant en matière de risque pour la santé et d'exposition aux particules fines. Des campagnes de mesures aux particules fines (…

Effect of training status on beta-range corticomuscular coherence in agonist vs. antagonist muscles during isometric knee contractions

Fabien Dal Maso, Marieke Longcamp, Sylvain Cremoux, David Amarantini

Antagonist muscle co-activation is thought to be partially regulated by cortical influences, but direct motor cortex involvement is not fully understood. Corticomuscular coherence (CMC) measures direct functional coupling of the motor cortex and muscles. As antagonist co-activation differs…
