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…

Hot ductility and flow stress of AISI 4130 and 52100-type steels

Damien Barbier, Jean-Dominique Guerin, Mirentxu Dubar, Vincent Benard, Sébastien Bonneau, Eli Saúl Puchi-Cabrera

The present communication reports the main findings of an investigation that has been conducted in order to examine the ductility of both the AISI 4130 and 52100 steel grades, in a wide range of temperatures, spanning from room temperature up to 1250 °C, deformed in tension at strain rates of…

On the aircraft conflict resolution problem: A VNS approach in a multiobjective framework

Antonio Alonso-Ayuso, Laureano Escudero, F Javier Martin-Campo, Nenad Mladenovic

The aircraft conflict resolution problem needs to provide response to such situation in which two or more aircraft violate the safety distances that must be kept during the flight. Then, given the aircraft trajectories, the aim consists of finding a new configuration such that every conflict…

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…

An approach for the evaluation of mobile decision support systems based on a knowledge discovery from data process : application in the medical field, Une approche pour l'évaluation des systèmes d'aide à la décision mobiles basés sur le processus d'extraction des connaissances à partir des données : application dans le domaine médical

Emna Ben Ayed

In this work, we are interested in Mobile Decision support systems (MDSS), which are based on the Knowledge Discovery from Data process (MDSS/KDD). Our work is dealing with the evaluation of these systems, but also to the evaluation in the KDD process itself. The proposed approach appends an…, Dans ce travail, on s’intéresse aux Systèmes d’Aide à la Décision Mobiles qui sont basés sur le processus d’Extraction des Connaissances à partir des Données (SADM/ECD). Nous contribuons non seulement à l'évaluation de ces systèmes, mais aussi à l'évaluation dans le processus d’ECD lui-…

Design Space exploration of FPGA-based accelerators with multi-level parallelism

Guanwen Zhong, Alok Prakash, Siqi Wang, Yun-Kuan Liang, Tulika Mitra, Smail Niar

Applications containing compute-intensive kernels with nested loops can effectively leverage FPGAs to exploit fine-and coarse-grained parallelism. HLS tools used to translate these kernels from high-level languages (e.g., C/C--), however, are inefficient in exploiting multiple levels of parallelism…

Fuzzy Edge Detection in Computed Tomography Through Genetic Algorithm Optimization

Mohamed Tahar Ali Gouicem, Mostepha Yahi, Abdelmalik Taleb-Ahmed

The ill posedness of the image reconstruction problem requires approached solution as a regularization of a specific criterion, in general, a penalty is imposed on the solution. The challenge is to avoid the smoothing of edges which are very important attributes of the image when it is regularized…
