Real-time monitoring and diagnosis of a train door mechatronic system

Laurent Cauffriez, Sébastien Grondel

For train manufacturers, a technical, economical, and societal key issue is the real-time monitoring and diagnosis of a train door in new generation of urban trains. Therefore, this paper proposes to deal with the modeling and diagnosis of a train door mechatronic system. For this purpose, the...

Flow measurement using micro-PIV and related temperature distributions within evaporating sessile drops of self-rewetting mixtures of 1-pentanol and water

John R. Christy, Khellil Sefiane, Johan C. Ebeling, Tobias Seewald, Souad Harmand

Recently interest has arisen in the use of so-called self-rewetting mixtures for micro-scale heat transfer systems. Such fluids, in which the surface tension can increase with increasing temperature, are expected to offer superior evaporative cooling performance by extending the region of operation...

Application specific multi-port memory customization in FPGAs

Gorker Alp Malazgirt, Hasan Erdem Yantir, Arda Yurdakul, Smail Niar

FPGA block RAMs (BRAMs) offer speed advantages compared to LUT-based memory designs but a BRAM has only one read and one write port. Designers need to use multiple BRAMs in order to create multi-port memory structures which are more difficult than designing with LUT-based multiport memories. Multi-...

A mixed integer linear programming approach for design space exploration in FPGA-based MPSoC

Bouthaina Dammak Masmoudi, Rachid Benmansour, Smail Niar, Mouna Baklouti, Mohamed Abid

Heterogeneous Multiprocessor System-on-Chip (Ht-MPSoC) architectures represent a promising approach as they allow a higher performance/energy consumption trade-off. In such systems, the processor instruction set is enhanced by application-specific custom instructions implemented on reconfigurable...

Study of a Taylor-Couette-Poiseuille flow in an annular channel with a slotted rotor

Nicolas Lancial, Federico Torriano, François Beaubert, Souad Harmand, Gilles Rolland

This paper investigates a Taylor-Couette-Poiseuille flow in an annular channel of a slotted rotating inner cylinder, corresponding to a salient pole hydrogenerator. The purpose of this study is to improve the understanding of flow and thermal phenomena in electrical machines using a simplified...

Time Series Modelling and Forecasting of Emergency Department Overcrowding

Farid Kadri, Fouzi Harrou, Sondès Chaabane, Christian Tahon

Efficient management of patient flow (demand) in emergency departments (EDs) has become an urgent issue for many hospital administrations. Today, more and more attention is being paid to hospital management systems to optimally manage patient flow and to improve management strategies, efficiency...

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...

Complementary tribometers for the analysis of contact phenomena in grinding

Eduardo García, José Antonio Sánchez, Damien Méresse, Iñigo Pombo, Laurent Dubar

The characterization of friction and tribological phenomena occurring in grinding requires reliable experimental input data. Up to now, existing test benches exhibit important limitations. Steep thermal gradients and elastic deformations of both machine structure, and rubbing elements are the main...

Folk-IS: Opportunistic Data Services in Least Developed Countries

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leïla Kloul, Nathalie Mitton, Philippe Pucheral

According to a wide range of studies, IT should become a key facilitator in establishing primary education, reducing mortality and supporting commercial initiatives in Least Developed Countries (LDCs). The main barrier to the development of IT services in these regions is not only the lack of...

Sliding Mode Control of Biglide Planar Parallel Manipulator

Mustapha Litim, Benyamine Allouche, Abdelhafid Omari, Antoine Dequidt, Laurent Vermeiren

This work presents the control of a two-degree of freedom parallel manipulator using nonlinear sliding mode approach. The aim is to achieve a robust control for trajectory tracking. The control is based on the inverse dynamic model in the Cartesian space of the parallel manipulator. Kinematic...
