Prediction of performance of Stirling engine using least squares support machine technique

Mohammad Hossein Ahmadi, Mohammad Ali Ahmadi, Milad Ashouri, Astarei Razie, Roghayeh Ghasempour, Fethi Aloui

Stirling engine is an environmental friendly heat engine which could reduce CO2 emission through combustion process. Output power, shaft torque and brake specific fuel consumption represent the efficiency and robustness of the Stirling engines. The present research tries to determine the three...

Modelling Laminate Failure in Composite Materials for Automotive Applications

David Moncayo, F. Köster, Pedro P Camanho, Daniel Coutellier, S. Hartmann

In order to capture the complexity of material failure it is necessary to understand that the performance of FE models depends on a fair use and a fair modeling of composite materials. Based on previous research works, the prognosis capabilities of the current material definitions in LS-DYNA will...

Relationship between brightness and roughness of polypropylene abraded surfaces

Adrien van Gorp, Maxence Bigerelle, Denis Najjar

This article proposes to analyze the relation between gloss and roughness of surfaces of polypropylene samples abraded at different magnitudes. Experiments consist of mechanical polishing at different grades, roughness profiles measurement, and specular light reflectometry with three incidence...

Improvement of a non energy-consuming system: A gamma Stirling engine

Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

In this paper, the classical adiabatic model was chosen. The assumption of perfect gas working fluid was replaced by that of a real gas working fluid. This last assumption was defined by the van der Waals state equation. A Gamma type Stirling engine functioning with a maximum filling pressure of 10...

A general variable neighbourhood search for the multi-product inventory routing problem

Anis Mjirda, Bassem Jarboui, Jelena Mladenović, Christophe Wilbaut, Said Hanafi

The inventory routing problem (IRP) deals with the study of the inter-relationship between two important activities in the supply chain: transportation of commodities and inventory management. In this paper, we study a variant of the multi-product IRP and we propose a general variable neighbourhood...

A quasi-static 3D model of wheelchair propulsion

Isam Hilal, Philippe Pudlo

The use of theoretical models is an alternative for studying the configuration of manual wheelchairs. Richter and Morrow proposed one of the theoretical models used to study propulsion in manual wheelchairs. However this analytical model is limited to use in the sagittal plane. This article...

I can't reach it! Focus on theta sensorimotor rhythm toward a better understanding of impaired action-perception coupling

Yannick Daviaux, Sylvain Cremoux, Jessica Tallet, David Amarantini, Christophe Cornu, Thibault Deschamps

It is known that anxiety (ANX) impairs action–perception coupling. This study tests whether this impairment could be associated with an alteration of the sensorimotor function. To this aim, the cortical activities underlying the sensorimotor function were recorded in twelve volunteers in a reach-to...

An enhanced experimental procedure to rationalize on the impairment of perception of action capabilities

Yannick Daviaux, Sylvain Cremoux, Jessica Tallet, David Amarantini, Christophe Cornu, Thibault Deschamps

It is well documented that changes in the physiological states of the perceiver-actor influence the perception of action capabilities. However, because experimental procedures of most studies involved a limitless availability for stimuli visual encoding and perceptual strategies, it remains...
