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...

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...

The influence of shoe aging on children running biomechanics

Alexis Herbaut, Pascale Chavet, Maxime Roux, Nils Gueguen, Franck Barbier, Emilie Simoneau-Buessinger

Athletic children are prone to overuse injuries, especially at the heel and knee. Since footwear is an extrinsic factor of lower limb injury risk, the aim of this study was to assess the influence of shoe aging on children running biomechanics. Fourteen children active in sports participated in a...

Solving the maximum min-sum dispersion by alternating formulations of two different problems

Zhazira Amirgaliyeva, Nenad Mladenovic, Raca Todosijević, Dragan Urošević

The maximum min-sum dispersion problem aims to maximize the minimum accumulative dispersion among the chosen elements. It is known to be strongly NP-hard problem. In this paper we present heuristic where the objective functions of two different problems are shifted within variable neighborhood...

On Strategies to Fix Degenerate k-means Solutions

Daniel Aloise, Nielsen Castelo Damasceno, Nenad Mladenovic, Daniel Nobre Pinheiro

k-means is a benchmark algorithm used in cluster analysis. It belongs to the large category of heuristics based on location-allocation steps that alternately locate cluster centers and allocate data points to them until no further improvement is possible. Such heuristics are known to suffer from a...

Probabilistic Tabu search with multiple neighborhoods for the Disjunctively Constrained Knapsack Problem

Mariem Ben Salem, Said Hanafi, Raouia Taktak, Hanene Ben-Abdallah

Given a set of items, each with a profit and a weight and a conflict graph describing incompatibilities between items, the Disjunctively Constrained Knapsack Problem is to select the maximum profit set of compatible items while satisfying the knapsack capacity constraint. We develop a probabilistic...

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...

Predicting fluorescence quantum yield for anisole at elevated temperatures and pressures

Qianlong Wang, Khanh-Hung Tran, Céline Morin, Jérôme Bonnety, Guillaume Legros, Philippe Guibert

Aromatic molecules are promising candidates for using as a fluorescent tracer for gas-phase scalar parameter diagnostics in a drastic environment like engines. Along with anisole turning out an excellent temperature tracer by Planar Laser-Induced Fluorescence (PLIF) diagnostics in Rapid Compression...

Marangoni Flow Induced Evaporation Enhancement on Binary Sessile Drops

Pin Chen, Souad Harmand, Safouene Ouenzerfi, Jesse Schiffler

The evaporation processes of pure water, pure 1-butanol, and 5% 1-butanol aqueous solution drops on heated hydrophobic substrates are investigated to determine the effect of temperature on the drop evaporation behavior. The evolution of the parameters (contact angle, diameter, and volume) during...

Thermal Topology Optimization of a Three-Layer Laminated Busbar for Power Converters

Oriol Puigdellivol, Damien Méresse, Yvonnick Le Menach, Souad Harmand, Jean-Francois Wecxsteen

This paper focuses on a topology optimization method for laminated busbars in power converters that minimizes the quantity of copper used while keeping the temperature under the allowed limits. Busbars are widely studied for adding their stray inductance to the commutation loop, which causes surge...
