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...

EQUITAS: A tool-chain for functional safety and reliability improvement in automotive systems

Reda Nouacer, Manel Djemal, Smail Niar, Gilles Mouchard, Nicolas Rapin, Jean-Pierre Gallois, Philippe Fiani, François Chastrette, Arnault Lapitre, Toni Adriano, Bryan Mac-Eachen

To support advanced features such as hybrid engine control, intelligent energy management, and advanced driver assistance systems, automotive embedded systems must use advanced technologies. As a result, systems are becoming distributed and include dozens of Electronic Control Units (ECU). On the...

Robust speaker identification system over AWGN channel using improved features extraction and efficient SAD algorithm with prior SNR estimation

Riadh Ajgou, Salim Sbaa, Said Ghendir, Ali Chemsa, Abdelmalik Taleb-Ahmed

This paper motivates the combination of Autoregressive (AR) parameters and Mel Frequency Cepstral Coefficients (MFCC) features for remote robust text-independent speaker identification. All speaker identification techniques start by converting the raw speech signal into a sequence of acoustic...

Experimental Study of Heat and Mass Transfer for Liquid Film Evaporation along a Vertical Plate Covered With a Porous Layer

Amine Terzi, Sadok Ben Jabrallah, Souad Harmand

In this paper, we realized an Experimental study of heat and mass transfer for liquid evaporation along a vertical plate covered with a porous layer. To develop this study, an experimental dispositive was realized. To highlight the effect of the addition of a porous layer on the phenomenon of...

Local stability of discrete-time TS fuzzy systems

Zsofia Lendek, Jimmy Lauber

This paper considers local stability analysis of discrete-time Takagi-Sugeno fuzzy systems, for which classically in the TS literature only global stability is considered. Using a common quadratic and nonquadratic Lyapunov function, respectively, LMI conditions are developed to establish local...

Multiscale roughness analysis of engineering surfaces: A comparison of methods for the investigation of functional correlations

Gaëtan Le Goïc, Maxence Bigerelle, Serge Samper, Hugues Favrelière, Maurice Pillet

This study investigates the correlations between the topography of different damaged rough surfaces and process conditions. Several surfaces are measured and compared to determine if they can be discriminated. The analysis is performed by using Gaussian Filtering, Wavelet Transform and a more...

Experimental Investigations on Oscillatory Couette Taylor Flow Wall Shear Stress Behavior using Electrochemical Technique: Low Modulation Effect

Emna Berrich, Fethi Aloui, Jack M Legrand

In the simplest and original case of study of the Taylor–Couette TC problems, the ﬂuid is contained between a ﬁxed outer cylinder and a concentric inner cylinder which rotates at constant angular velocity. Much of the works done has been concerned on steady rotating cylinder(s) i.e. rotating...

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...

Integer programming based approaches for multi-trip location routing

Rita Macedo, Bruna Ramos, Cláudio Alves, José Manuel Valério de Carvalho, Said Hanafi, Nenad Mladenovic

The multi-trip location routing problem consists in selecting the depots to open and the routes that should be performed to serve a set of clients at minimum cost. The multi-trip variant considers the possibility for a vehicle to perform more than a single route during the planning period, and...
