Nonquadratic Lyapunov function for continuous TS fuzzy models through their discretization

Ameni Ellouze, François Delmotte, Jimmy Lauber, Mohamed Chtourou, Mohamed Ksantini

Since the beginning of the fuzzy control theory, results have been obtained independently for continuous and discrete models. It is still quite difficult to use nonquadratic Lyapunov functions for the continuous case, while this is much easier for the discrete case. This approach tries to put a...

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...

Efficient meshless SPH method for the numerical modeling of thick shell structures undergoing large deformations

Jun Lin, Hakim Naceur, Daniel Coutellier, Abdel Laksimi

The objective of this paper is to present an extension of the Lagrangian Smoothed Particle Hydrodynamics (SPH) method to solve three-dimensional shell-like structures undergoing large deformations. The present method is an enhancement of the classical stabilized SPH commonly used for 3D continua,...

A Combined DMI–RLS Algorithm in Adaptive Processing Antenna System

Aounallah Naceur, Merahi Bouziani, Abdelmalik Taleb-Ahmed

Smart antenna systems are rapidly emerging as one of the key technologies that can enhance overall wireless communications system performance. The purpose of this paper is to develop a novel adaptive beamforming system from two adaptive algorithms that are known in the literature as spatial filters...

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...

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...

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...
