An experimental work on the effect of the radius of rotation on the performance of revolving heat pipe (RVHP)

Hamdy Hassan, Souad Harmand

Rotating heat pipe uses centrifugal acceleration to transfer condensed liquid from the condenser to evaporator. Revolving heat pipe (RVHP) is a rotating heat pipe but its axis of rotation is parallel to and offset from its central axis. This paper presents an experimental work on the effect of…

The robust uncapacitated multiple allocation p-hub median problem

El-Ghazali Talbi, Raca Todosijević

In this paper we study the uncapacitated multiple allocation p-hub median problem and propose several ways to deal with the uncertainty that may occur in the flow. More precisely, the paper introduces a new way to quantify the robustness of a solution in the presence of uncertainities. The main…

Impaired corticomuscular coherence during isometric elbow flexion contractions in humans with cervical spinal cord injury

Sylvain Cremoux, Jessica Tallet, Fabien Dal Maso, Eric Berton, David Amarantini

After spinal cord injury (SCI), the reorganization of the neuromuscular system leads to increased antagonist muscles' co-activationthat is, increased antagonist vs. agonist muscles activation ratioduring voluntary contractions. Increased muscle co-activation is supposed to result from reduced…

Solving the clique partitioning problem as a maximally diverse grouping problem

Jack Brimberg, Stefana Janićijević, Nenad Mladenovic, Dragan Urošević

In this paper we show that the clique partitioning problem can be reformulated in an equivalent form as the maximally diverse grouping problem (MDGP). We then modify a skewed general variable neighborhood search (SGVNS) heuristic that was first developed to solve the MDGP. Similarly as with the…

Experimental study of the strain rate dependence of a synthetic gel for ballistic blunt trauma assessment

Anthony Bracq, Grégory Haugou, Rémi Delille, Franck Lauro, Sébastien Roth, Olivier Mauzac

The mechanical characterization of a polymer gel used as reference backing material for blunt ballistic impact interpretation is performed at room temperature from quasi-static (0.002 s−1) up to high strain rates (1500 s−1). As very high strain tensile tests (350%) are conducted, an appropriate…

A general variable neighborhood search variants for the travelling salesman problem with draft limits

Raca Todosijević, Anis Mjirda, Marko Mladenovic, Said Hanafi, Bernard Gendron

In this paper, we present two general variable neighborhood search (GVNS) based variants for solving the traveling salesman problem with draft limits (TSPDL), a recent extension of the traveling salesman problem. TSPDL arises in the context of maritime transportation. It consists of finding optimal…

Comparing multiple correspondence and principal component analyses with biomechanical signals. Example with turning the steering wheel

Pierre Loslever, Jessica Schiro, François Gabrielli, Philippe Pudlo

The purpose of this article is to compare Principal Component Analysis (PCA) and a much less used method, i.e. MCA (Multiple Correspondence Analysis) with data being first changed into membership values to fuzzy space windows. For such a comparison, data from an experimental study about turning the…

Benefits of physical activities centered on the trunk for pregnant women

Eric Watelain, Antonio Pinti, Racha Doya, Cyril Garnier, Hechmi Toumi, Samuel Boudet

Objective: To examine the effect of a trunk exercise program on pain, quality of life (QoL) and physical health (PH) in the late pregnancy and post-partum periods as well as baby weight and size and delivery. Methods: 90 nulliparous women were allocated based on voluntarism to a training group (TG…

Stability analysis of switched linear systems on non-uniform time domain with unstable subsystems

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai, Serge Nicaise

In finite element computations, the choice of the mesh is crucial to obtain accurate solutions. In order to evaluate the quality of the mesh, a posteriori error estimators can be used. In this paper, we develop residual-based error estimators for magnetostatic problems with both classical…

Real-time wrist localization in color images based on corner analysis

Sofiane Medjram, Chaouki Babahenini, Abdelmalik Taleb-Ahmed, Yamina Mohamed Ben Ali

Hand detection and gestures recognition have become very popular in recent human-computer interaction systems. Although several methods of hand detection have been proposed in the literature, they exist few methods that use the wrist as a factor of detection, others impose constraints on the length…
