Validation of a new numerical weaving tool highlighting the influence of real yarn positions and shapes on their behaviour under impact

Mickael Lequin, E. Ferry, Benjamin Provost, Daniel Coutellier, François Boussu

In this study, a numerical simulation approach is used to measure the influence of yarn positions inside a 3D warp interlock fabric submitted to impact. Four numerical results have been compared to one experimental impact test. A first simulation is made directly from the experimental tomographic…

Holonic recursiveness with multi-agent system technologies

Sonia Suárez, Paulo Leitão, Emmanuel Adam

Recursive Systems are often needed or recommended for automatically deploy or build a software system composed of multiple entities on a large network, or on distributed locations, without a central control. We use the recursive definitions proposed in holonic systems, as the recursiveness is an…

Analysis of inverse method applied on sandwich probes

Emna Berrich, Fethi Aloui, Jack Legrand

Parallel plate disks (PPD) are often used for analyzing the effect of small amplitude oscillations with different frequencies. These devices allow the imposing of a well-known flow kinematics. Mass transfer problems and, particularly, convection-diffusion problems relating wall shear rate to mass…

Benchmarking Flexible Job-Shop Scheduling and Control Systems

Damien Trentesaux, Cyrille Pach, Abdelghani Bekrar, Yves Sallez, Thierry Berger, Thérèse Bonte, Paulo Leitão, José Barbosa

Benchmarking is comparing the output of different systems for a given set of input data in order to improve the system's performance. Faced with the lack of realistic and operational benchmarks that can be used for testing optimization methods and control systems in flexible systems, this…

Using the BCD model for risk analysis

Karima Sedki, Philippe Polet, Frédéric Vanderhaegen

In this paper, we are interested in addressing risk analysis. We propose an influence diagram-based approach that focuses on a Benefit, Cost, Deficit (BCD) model. The BCD model is proposed for studying the intentional deviant behaviors of human operators in a system. In this model, the consequences…

On Riemann and Weyl compatible tensors

Ryszard Deszcz, Małgorzata Głogowska, Jan Jełowicki, Miroslava Petrović-Torgašev, Georges Zafindratafa

We investigate semi-Riemannian manifolds satisfying some curvature conditions. Those conditions are strongly related to pseudosymmetry.

Robust Approximation of Singularly Perturbed Delay Differential Equations by the hp Finite Element Method

Serge Nicaise, Xenophontos Christos

Abstract. We consider the finite element approximation of the solution to a singularly perturbed second order differential equation with a constant delay. The boundary value problem can be cast as a singularly perturbed transmission problem, whose solution may be decomposed into a smooth part, a…

Estimation of Road Adhesion Coefficient Using Higher-Order Sliding Mode Observer for Torsional Tyre Model

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, D. Zhang, Q. Zhang, Michael Defoort

The estimation of friction coefficient for a vehicle when it traverses on different surfaces has been an important issue. In this paper, a super-twisting algorithm based sliding mode observer is proposed to estimate the road adhesion coefficient, treated as an unknown input in the dynamics of a…

Variable neighborhood search for location routing

Bassem Jarboui, Houda Derbel, Said Hanafi, Nenad Mladenovic

In this paper we propose various neighborhood search heuristics (VNS) for solving the location routing problem with multiple capacitated depots and one uncapacitated vehicle per depot. The objective is to find depot locations and to design least cost routes for vehicles. We integrate a variable…
