Wettability versus roughness: Multi-scales approach

Vanessa Belaud, Stéphane Valette, Guy Stremsdoerfer, Maxence Bigerelle, Stéphane Benayoun

These authors experimentally investigate the influence of multi-scale roughness on contact angle measurements, and they propose a model combining the Wenzel and Cassie–Baxter equations with the 3D roughness parameters defined by ISO25178. To do this, a generic methodology based on a statistical...

Multi-level homotopy perturbation and projection techniques for the reanalysis of quadratic eigenvalue problems: The application of stability analysis

Franck Massa, Bertrand Lallemand, Thierry Tison

Complex eigenvalue analysis is widely used to investigate the stability of a dynamical system with frictional contact. For finite element models, iterative solvers are needed to precisely calculate complex modes and eigenvalues. However, in cases such as reanalysis studies, optimization or...

The representative topography of worn hot rolling mill cylinders

Emilie Luc, Maxence Bigerelle, Raphaël Deltombe, Mirentxu Dubar

In this paper, a method is proposed to extract the most representative surface topography from n surfaces. A criterion is proposed that allows rejecting irrelevant topographical maps. Then, this methodology is applied on the hot rolling process, on replicas of industrial surfaces. These analyses...

Clustering cities based on their development dynamics and Variable neigborhood search

B. S. Zhikharevich, O. V. Rusetskay, Nenad Mladenovic

Clustering cities based on their socio-economic development in long time period is an important issue and may be used in many ways, e.g., in strategic regional planning. In this paper we continue our recent study where cumulative attribute for each year replaces nine other attributes, called ‘...

Determination of adequate regenerator for a Gamma-type Stirling engine

Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

This paper deals with an optimization of the Stirling engine regenerator’s. Firstly, different materials are experimented (Stainless Steel, Copper, aluminum and Monel 400). The engine performances and the state of each material after 15 h of use are considered. The Stainless steel was the material...

A variable neighborhood search for solving the multi-vehicle covering tour problem

Manel Kammoun, Houda Derbel, Mustapha Ratli, Bassem Jarboui

In this article, we consider a transportation problem with different kinds of locations: V , T, and W. The set T ⊂ V consists of vertices that must be visited through the use of potential locations in V and W consists of locations that must be covered. The problem consists in minimizing vehicle...

The heat equation under conditions on the moments in higher dimensions

Delio Mugnolo, Serge Nicaise

We consider the heat equation on the N-dimensional cube (0, 1)N and impose different classes of integral conditions, instead of usual boundary ones.Well-posedness results for the heat equation under the condition that the moments of order 0 and 1 are conserved had been known so far only in the case...

A variable neighborhood search algorithm for the vehicle routing problem with multiple trips

Mohamed Cheikh, Mustapha Ratli, Omar Mkaouar, Bassem Jarboui

The vehicle routing problem with multiple trips (V RP M T ) is a variant of thestandard (V RP ), where each vehicle can be used more than once during the workingperiod. For this NP-Hard problem, we propose a variable neighborhood searchAlgorithm in which four neighborhood structure are designed to...
