Sequential variable neighborhood descent variants: an empirical study on the traveling salesman problem

Anis Mjirda, Raca Todosijević, Said Hanafi, Pierre Hansen, Nenad Mladenovic

In a single local search algorithm, several neighborhood structuresare usually explored. The simplest way is todefine a single neighborhood as the union of all predefined neighborhood structures; the other possibility is tomake an order (or sequence) of the predefined neighborhoods,and to use them in…

Identification of the contribution of contact and aerial biomechanical parameters in acrobatic performance

Diane Haering, Aurore Huchez, Franck Barbier, Patrice Holvoët, Mickael Begon

Introduction Teaching acrobatic skills with a minimal amount of repetition is a major challenge for coaches. Biomechanical, statistical or computer simulation tools can help them identify the most determinant factors of performance. Release parameters, change in moment of inertia and segmental…

A new family of 2D-wavelength-time codes for OCDMA system with direct detection

Chahinaz Kandouci, A. Djebbari, Abdelmalik Taleb-Ahmed

A new family of two dimensional wavelength-time codes is proposed in this paper. Based on one-dimensional ZCC, it allows a higher cardinality without increasing the code length, while conserving the same correlation properties. Thus, the direct detection at the receiver can be used, thereby…

Optimization of an air-filled Beta type Stirling refrigerator, Optimisation d’un réfrigérateur à moteur Stirling à air de type bêta

Houda Hachem, Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

The Stirling machine has many successful applications mainly thanks to its high efficiency, fast cool-down, small size, light weight, low power consumption and high reliability (heating and cooling). A Beta type Stirling refrigerator is studied experimentally and numerically. The mathematical model…

Scheduling preventive railway maintenance activities with resource constraints

Rita Macedo, Rachid Benmansour, Abdelhakim Artiba, Nenad Mladenovic, Dragan Urošević

In this paper, we focus on the scheduling of preventive railway maintenance activities. The objective is to keep the railway infrastructure in good operating conditions at low costs, also taking into account the limited available resources in what concerns crew members. Equipments degrade with…

Macro-modeling of the strength and failure of multi-layer multi-steel grade spot welds: Connector formulation, assembly model and identification procedure

Rim Chtourou, Nicolas Leconte, Fahmi Chaari, Grégory Haugou, Eric Markiewicz, Bassem Zouari

The aim of this paper is to investigate the mechanical strength and the failure of three-sheet multi-steel grade Resistance Spot Welded assemblies (RSW) using experimental and numerical tests. A macroscopic modeling approach, using three connector elements, dedicated to the crashworthiness analysis…

Clustering approach in maintenance of capillary railway network

Danijela Đorić, Abdessamad Ait El Cadi, Said Hanafi, Nenad Mladenovic, Abdelhakim Artiba

Maintenance optimization of railway infrastructure includes several kinds of aspects, such as safety, economic, operational, organization and regulatory issues. Among them the regulatory issues, that are fixed, increase the maintenance costs significantly. This is especially true in so-called…
