Thermal diffusivity identification by 2 nde derivative analysis of transient temperature profile

Damien Méresse, Souad Harmand, Ali Grine

This paper deals with a new method to identify the thermal diffusivity of isotropic materials. Contrary to the flash method, a continuous and constant heating is applied on the rear surface of the sample. An analytical solution of the 1-D transient equation is developed based on Green's…

A New Optimal Neuro-Fuzzy Inference System for MR Image Classification and Multiple Scleroses Detection

Hakima Zouaoui, Abdelouahab Moussaoui, Abdelmalik Taleb-Ahmed, Mourad Oussalah

In the present article, we propose a new approach for the segmentation of the MR images of the Multiple Sclerosis (MS) which is an autoimmune inflammatory disease affecting the central nervous system. Our algorithm of segmentation is composed of three stages: segmentation of the brain into regions…

FMRI Data Analysis Using Dempster-Shafer Method with Estimating Voxel Selectivity by Belief Measure

Abdelouahab Attia, Abdelouahab Moussaoui, Abdelmalik Taleb-Ahmed

In the functional Magnetic Resonance Imaging (fMRI) data analysis, detecting the activated voxels is a challenging research problem where the existing methods have shown some limits. We propose a new method wherein brain mapping is done based on Dempster-Shafer theory of evidence (DS) that is a…

Use of the PIV and Electrochemical Techniques to Experimentally Characterize the Couette-Taylor- Poiseuille Flow Instabilities

Wafik Abassi, Fethi Aloui, Sassi Ben Nasrallah, Jack Legrand

The Taylor-Couette problem is a fundamental model in bifurcation theory and hydrodynamic stability. The inner cylinder rotation generates a flow pattern known by a transition to turbulence through a sequence of successive hydrodynamic instabilities. The effect of an imposed axial flow on the…

Some improvements for determining the hardness of homogeneous materials from the work-of-indentation

Didier Chicot, Michel Yetna N'Jock, Francine Roudet, Xavier Decoopman, Mariana H. Staia, Eli Saúl Puchi-Cabrera

In this work, the total and plastic hardness of a variety of materials were determined from the work-of-indentation. We show that by taking into account the influence of the tip defect, both the total and plastic hardness have the same values and that the hardness-load dependence is considerably…

Behaviour of flow dynamics over an asymmetrical deep cavity at high reynolds numbers

Denis Cornu, Laurent Keirsbulck, Camila Chovet, Marc Lippert, Franck Kerhervé, Fethi Aloui

This paper presents an experimental study, based on the geometry of a cavity, about the flow effects using quantitative particle image velocimetry (PIV) and, local and instantaneous pressure measurements. Three configurations of rectangular deep cavities were investigated: symmetric and asymmetric…

An approach to the prioritization of sustainable maintenance drivers in the TBL framework

Sandro de Paula Pires, Olivier Sénéchal, Eduardo Rocha Loures, José Fernando Jimenez

The current sustainable production model is supported by the Triple Bottom Line (TBL) concept and its three dimensions: economic, environmental, and social. This paper aims to propose an approach to identify and prioritize the attributes of the TBL dimensions, extracted from the Global Reporting…

Advanced model based air path management using a discrete-angular controller in idle-speed context

Thomas Laurain, Jimmy Lauber, Reinaldo Martinez Palhares

This paper aims to present an original methodology to design a controller for the air path management considered as a nonlinear system that is presented as a periodic discrete Takagi-Sugeno (TS) model. A transformation is realized to translate the periodic behavior into a classic discrete model…

An Iterative Greedy Insertion Technique for Flexible Job Shop Scheduling Problem

Azzedine Bekkar, Oualid Guemri, Abdelghani Bekrar, Nassima Aissani, Bouziane Beldjilali, Damien Trentesaux

This paper studies the problem of scheduling in a flexible job shop. A greedy heuristic is developed to solve precisely the sequencing (allocation) problem. The principle of this approach is to iteratively insert operations on the machines until the objective of minimizing the Cmax (makespan) is…
