Variations in Patterns of Muscle Activity Observed in Participants Walking in Everyday Environments: Effect of Different Surfaces

Julien Lebleu, Ross Parry, Camille Bertouille, Marine de Schaetzen, Philippe Mahaudens, Laura Wallard, Christine Detrembleur

Purpose: The purpose of this study was to examine variations in lower limb surface electromyography (EMG) activity when individuals walked on different outdoor surfaces and to characterize the different potential motor strategies. Method: Forty healthy adult participants walked at a self-selected…, Objectif : examiner les variations à l’activité électromyographique (EMG) de surface des membres inférieurs lorsqu’une personne marche sur diverses surfaces extérieures et caractériser les diverses stratégies motrices potentielles. Méthodologie : au total, 40 participants adultes en santé ont…

Less is more approach: basic variable neighborhood search for the obnoxious p -median problem

Nenad Mladenovic, Abdulaziz Alkandari, Jun Pei, Raca Todosijević, Panos M. Pardalos

The goal of the less is more approach (LIMA) for solving optimization problems that has recently been proposed in Mladenović et al. (2016) is to find the minimum number of search ingredients that make a heuristic more efficient than the currently best. In this paper, LIMA is successfully applied to…

Numerical and experimental investigation of impinging turbulent flow of twin jets against a wall

Mohamad Ali Modaresi, Ebrahim Shirani, Mahmood Charmiyan, Fethi Aloui, Amine Koched, Michel Pavageau

In the present study, impinging of vertical twin jet against a horizontal plate is investigated numerically and experimentally. Four two-equation RANS based turbulence models are used and their capabilities to simulate such complicated turbulent ow are examined. The inlet jet hydraulic diameters…

Analysis of surface roughness morphology with TRIZ methodology in automotive electrical contacts: Design against third body fretting-corrosion

T. W. Liskiewicz, K. J. Kubiak, D. L. Mann, Thomas Mathia

Electrical connectors for motor vehicles are essential for the safe and efficient operation of a vehicle. However, their durability is limited by fretting induced corrosion. This type of surface damage is observed between two interconnected surfaces exposed to vibration and temperature variations.…

Benefits of a four-week functional restoration program in chronic low back pain patients and three-month follow-up: focus on paraspinal muscle aerobic metabolism responses to exercise

Agathe Anthierens, Nicolas Olivier, André Thévenon, Patrick Mucci

Background: Chronic low back pain (CLBP) is a major health concern characterized by paraspinal muscle fatigability. This can be improved following a functional restoration program. Muscle fatigability can be related to impairment in aerobic metabolism responses. In this study, we investigated…

Conception centrée utilisateur d'aides techniques pour des utilisateurs en situation de handicap avec troubles de la communication : retour d'expérience pour une participation systématique de leur écosystème, User-centered design of assistive technologies for disabled users with communication disorders: feedback for a systematic participation of their ecosystem

Yohan Guerrier, Nadine Vigouroux, Christophe Kolski, Frédéric Vella, Marine Guffroy, Philippe Teutsch

La conception centrée utilisateur (CCU) est aujourd’hui une référence. Cependant lorsque les utilisateurs présentent des troubles de la communication, ces derniers rencontrent de grandes difficultés pour participer aux activités de la CCU. Leur environnement humain (famille, professionnel, médical…, User Centred Design (UCD) is now a reference. However, when users have communication difficulties, they have great difficulty in participating in UCD activities. Their human environment (family, professional, medical), which we call an ecosystem, is therefore essential for the participation of…

Manufacturing 4.0 Operations Scheduling with AGV Battery Management Constraints

Moussa Abderrahim, Abdelghani Bekrar, Damien Trentesaux, Nassima Aissani, Karim Bouamrane

The industry 4.0 concepts are moving towards flexible and energy efficient factories. Major flexible production lines use battery-based automated guided vehicles (AGVs) to optimize their handling processes. However, optimal AGV battery management can significantly shorten lead times. In this paper…

An FPGA comparative study of high-level and low-level combined designs for HEVC intra, inverse quantization, and IDCT/IDST 2D modules

Ahmed Ben Atitallah, Manel Kammoun, Karim Mohamed Abedallah Ali, Rabie Ben Atitallah

Two main design methods are currently widely adopted in dealing with complex signal processing algorithms. The first method is based on low-level synthesis (LLS), which consists in writing the hardware description languages (HDL) code manually. However, the second method, called high-level…

A Multiple-Parameterization Approach for local stabilization of constrained Takagi-Sugeno fuzzy systems with nonlinear consequents

Pedro H.S. Coutinho, Rodrigo Araujo, Tran Anh-Tu Nguyen, Reinaldo Martinez Palhares

This paper addresses the local stabilization of constrained nonlinear systems with input saturation described by Takagi-Sugeno fuzzy models with nonlinear consequents. To reduce the design conservativeness, we propose a new delayed multiple-parameterization control approach based on a nonquadratic…
