Roughness characterization of the galling of metals

Cédric Hubert, Julie Marteau, Raphaël Deltombe, Y Chen, Maxence Bigerelle

Several kinds of tests exist to characterize the galling of metals, such as that specified in ASTM Standard G98. While the testing procedure is accurate and robust, the analysis of the specimenʼs surfaces (${\rm area}=1.2\;{\rm cm}$) for the determination of the critical pressure of galling remains…

New MIP model for multiprocessor scheduling problem with communication delays

Abdessamad Ait El Cadi, Rabie Ben Atitallah, Said Hanafi, Nenad Mladenovic, Abdelhakim Artiba

In this paper we consider scheduling tasks on a multiprocessor system, taking into account communication delays. We propose a new Mixed Integer Program (MIP) formulation that drastically reduces both the number of variables and the number of constraints, when compared to the best mathematical…

A Methodology for a New Qualified Numerical Model of a 2-Stroke Diesel Engine Design

Stéphanie Cagin, Xavier Fischer, Nachida Bourabaa, Eric Delacourt, Céline Morin, Daniel Coutellier

This paper presents a methodology to determine and to formalize all the variables involved in a CFD model of a 2-stroke diesel engine. The formalization includes the establishing of the values domain and the research of relations between the variables. The formalization can be followed by a…

Characterization and micromechanical modeling of the human cranial bone elastic properties

Jamila Rahmoun, Audrey Auperrin, Rémi Delille, Hakim Naceur, Pascal Drazetic

This paper is devoted to the experimental characterization and micromechanical modeling of the elastic behavior of the human cranial bone. Three points bending tests on the frontal, parietal and temporal bone specimens have been performed to determine their mechanical characteristics under quasi-…

Heat transfer coefficient distribution on the pole face of a hydrogenerator scale model

Federico Torriano, Nicolas Lancial, Melanie Levesque, Gilles Rolland, Claude Hudon, François Beaubert, Jean-Francois Morissette, Souad Harmand

This paper focuses on the effect of rotation on heat transfer mechanisms in rotating machines with the purpose to improve the understanding of thermal phenomena and cooling of hydrogenerators. Using a simplified scale model equipped with a heated pole, it was possible to measure the temperature…

Fast System Level Benchmarks for Multicore Architectures.

Alper Sen, Gokcehan Kara, Etem Deniz, Smail Niar

We present a framework that automatically generates system level synthetic benchmarks from traditional benchmarks. Synthetic benchmarks have similar performance behavior as the original benchmarks that they are generated from and they can run faster. Synthetics can also be used as proxies where…

Design Space Exploration for Customized Asymmetric Heterogeneous MPSoC.

Bouthaina Damak, Rachid Benmansour, Mouna Baklouti, Smail Niar, Mohamed Abid

Modern FPGA allows the design of very complex System-on-Chips (SoC). To fulfil modern application requirements, in terms of performance/energy consumption ratio, Heterogeneous Multiprocessor System-on-Chip (Ht- MPSoC) architectures represent a promising solution. In such systems, the processor…

HOG Feature Extractor Hardware Accelerator for Real-Time Pedestrian Detection.

Maryam Hemmati, Morteza Biglari-Abhari, Stevan Berber, Smail Niar

Histogram of oriented gradients (HOG) is considered as the most promising algorithm in human detection, however its complexity and intensive computational load is an issue for real-time detection in embedded systems. This paper presents a hardware accelerator for HOG feature extractor to fulfill…
