Wetting of anisotropic sinusoidal surfaces—experimental and numerical study of directional spreading

Fisher Guillaume, Maxence Bigerelle, Krzysztof Kubiak, T.G. Mathia, Z. Khatir, Karine Anselme

Directional wettability, i.e. the variation of wetting properties, depending on the surface orientation, can be achieved by anisotropic surface texturing. A new high-precision process can produce homogeneous sinusoidal surfaces (in particular, parallel grooves) at the microscale, with a nanoscale...

An Experimental and Numerical Study on the Effects of the Flat Heat Pipe Wick Structure on Its Thermal Performance

Hamdy Hassan, Souad Harmand

This paper presents an experimental and numerical work on the effect of flat heat pipe construction on the cooling of an electronic component. The flat heat pipe is heated via 1-cm-diameter circular electrical resistance (the evaporator side), and the other side (the condenser side) is cooled by...

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...

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...

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...

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...

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...

Reducing myopic behavior in FMS control: A semi-heterarchical simulation–optimization approach

Gabriel Zambrano Rey, Thérèse Bonte, Vittaldas V. Prabhu, Damien Trentesaux

Heterarchical FMS control architectures localize decisional capabilities in each entity, resulting in highly reactive, low complexity control architectures. Unfortunately, these architectures present myopic behavior since decisional entities have limited visibility of other decisional entities’...
