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...

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...

Experimental study on the stability of an impedance-type force-feedback architecture based on an augmented-state observer for a haptic system under time delay using a LMI approach

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

One of the most important performance measures of a haptic interface may be characterized by its behaviour in the implementation of a virtual wall in terms of the biggest value of the virtual stiffness that still leaves the device stable. This value depends on many factors including time delays and...

Maintenance decision support for sustainable performance: problems and research directions at the crossroads of health management and eco-design

Olivier Sénéchal

Despite companies progressively taking sustainable performance into account through various governmental incentives and policies, most still have their own strategic, tactical or operational targets based essentially on economic criteria (turnover, productivity, inventory valuation...). Since the...

Experimental Study of Flow Control on Bluff Body using Piezoelectric Actuators

Nabil Tounsi, Rafika Mestiri, Laurent Keirsbulck, Hamid Oualli, Samir Hanchi, Fethi Aloui

Active flow control is experimentally investigated on a car-type bluff body. The actuation is based on a synthetic jet actuator placed at the top of the Ahmed body rear window. In the present paper, a synthetic jet characterization is presented, the frequencies and the optimal amplitudes with...

Modeling transistor level masking of soft errors in combinational circuits

Ihsen Alouani, Smail Niar, Yassin El Hillali, Atika Rivenq

Technology scaling in modern electronic circuits shrinks the transistor size and dramatically increases the sensitivity of semiconductor devices to radiations. Consequently, soft errors emerged as a serious reliability threat in both sequential and combinational circuits. To accurately estimate...

A co-design space exploration tool for avionic high performance heterogeneous embedded architectures

Geoffroy Pertuisot, Nicolas Belanger, Yassin El Hillali, Smail Niar, Atika Rivenq

Avionics in the helicopter manufacturers' landscape faces new challenges. Whereas customers raise continuously their needs in terms of new functions and embedded systems performances, certification authorities maintain complex rules to fulfill for parallel computing. This constraining...

An Approach for the Selection of Evaluation Methods for Interactive Adaptive Systems Using Analytic Hierarchy Process

Amira Dhouib, Abdelwaheb Trabelsi, Christophe Kolski, Neji Mahmoud

The evaluation of interactive adaptive systems is the source of many difficulties for novice evaluators as well as for expert ones. Issues arise in the need to identify the appropriate evaluation methods to be used for a given evaluation context. This paper proposes an approach for the choice of...

A Design Model for Tangible Interaction: Case Study in Waste Sorting

Clémentine Havrez, Sophie Lepreux, Yoann Lebrun, Sylvain Haudegond, Pierrette Ethuin, Christophe Kolski

In this paper, we propose a design model for applications with Tangible User Interfaces (TUI). This model aims to support designers in organizing the different elements and their relationships. We then implement the model through the design of a Serious Game for an RFID tabletop that uses tangible...
