Increased antagonist muscle activity in cervical SCI patients suggests altered reciprocal inhibition during elbow contractions

Sylvain Cremoux, David Amarantini, Jessica Tallet, Fabien Dal Maso, Eric Berton

Objective: After spinal cord injury (SCI), the antagonist muscles activation is increased during voluntary contractions and reflex conditioning protocols. This increase can be the result of both muscle atrophy and reciprocal facilitation mechanism. It remains however unclear to what extent…

Turbulent Flows Structures Crossing Conical Diffusers: Angle Effect Analysis using PIV Technique and POD for Post-Processing

Emna Berrich, Fethi Aloui, D Pierrat, L Gros, Anthony Couzinet, Jack Legrand

In this work, we investigated experimentally the hydrodynamics of flows crossing conical diffusers. On our previous work (Aloui et al., 2011), CFD turbulent models were validated for flows crossing the critical angle (2α=16°). Indeed, the PIV data base constructed was exploited to validate a…

HCI Engineering Integrated with Capability Maturity Models

Taisa Guidini Gonçalves, Káthia Marçal de Oliveira, Christophe Kolski

Even though coming from different communities, Software Engineering (SE) and Human-Computer Interaction (HCI) engineering have similar goals: the definition of methods, techniques and standards to support the development of software systems, and, in particular for HCI, of interactive systems.…

Ergonomics of load transport in the seed harvesting ant Messor barbarus Linnæus, 1767: morphology influences transportation method and efficiency

Abel Bernadou, Antoine Felden, Mathieu Moreau, Pierre Moretto, Vincent Fourcassié

We studied in the field the load transport behaviour of workers of the polymorphic Mediterranean seed harvester ant Messor barbarus. Individual ants used two different methods to transport food items: carrying or dragging. The probability of dragging instead of carrying varied significantly with…

Scavenging Process Analysis in a 2-Stroke Engine by CFD Approach for a Parametric 0D Model Development

Stéphanie Cagin, Nachida Bourabaa, Eric Delacourt, Céline Morin, Xavier Fischer, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

This paper presents a method to improve cylinder design of 2-stroke auto-ignition engine based on a CFD (Computational Fluid Dynamics) study of internal flows in the chamber and an unsteady global 0D parametric approach. In 2-stroke engine, scavenging process plays an important role regarding…

A new reduced model of scavenging to optimize cylinder design

Stéphanie Cagin, Xavier Fischer, Eric Delacourt, Nachida Bourabaa, Céline Morin, Daniel Coutellier, Bertrand Carre, Sylvain Loumé

This paper presents the development of a new scavenging model to optimize cylinder design. The developed model explicitly integrates some of the cylinder’s design and environmental variables to describe flows during the scavenging process. Then, based on the reduced model, an optimization phase was…

A classification and Comparison of Usability Evaluation Methods for Interactive Adaptive Systems

Amira Dhouib, Abdelwaheb Trabelsi, Christophe Kolski, Neji Mahmoud

Usability is a crucial factor for interactive adaptive system success. Several methods have been proposed to support the usability evaluation of interactive adaptive systems. However, the diversity of these methods leaves the evaluators wondering what would be the most appropriate usability…

An Efficient Matheuristic for the Multicommodity Fixed-Charge Network Design Problem

Bernard Gendron, Said Hanafi, Raca Todosijević

In this paper we study the Multicommodity Fixed-Charge Network Design problem. We propose an Iterative linear programming-based heuristic for solving this NP hard problem. The proposed heuristics have been tested on the benchmark instances from the literature. The quality of solutions obtained by…

Les conditions de conception et d'exploitation des systèmes ferroviaires au sein de l'U.E sont régies par des directives, des règlements, des décrets, normes qui permettent, notamment, d'assurer la sécurité du système global de transport. Cependant, chaque état membre de l'U.E.…, In the E.U, safety railway system design and operational terms are governed by directives, regulations, decrees, standards to ensure the safety of the global system. However, based on its own technical and operational concepts, each state member of the E.U. has developed its own safety rules. By…
