Dynamic behavioural model for assessing impact of regeneration actions on system availability: Application to weapon systems

Maxime Monnin, Benoît Iung, Olivier Sénéchal

Mastering system availability all along the system life cycle is now a critical issue with regards to systems engineering. It is more true for military systems which operate in a battle context. Indeed as they must act in a hostile environment, they can become unavailable due to failures of or…

Caractérisation de la coordination motrice des membres inférieurs lors de la marche des patients hémiparétiques, Lower limb coordination patterns in hemiparetic gait

Emilie Hutin

La parésie, l'hyperactivité musculaire et la rétraction des tissus mous sont les principaux mécanismes physiopathologiques responsables de la dégradation de la marche dans l'hémiparésie. Lors de la prise en charge du patient hémiparétique, le questionnement du clinicien s'articule…, Paresis, muscle hyperactivity and soft tissue retraction are the main mechanisms responsible for the gait disturbance in hemiparesis. In the rehabilitation management of hemiparetic patients, clinicians try to determine the responsibility of each mechanism, and to quantify the impact of treatments…

Analyse et modélisation du mouvement de transfert de la personne paraplégique, Analysis and modelisation of paraplegic individuals transfer movement

Jean-François Debril

Le transfert latéral chez la personne paraplégique, mouvement d’accès ou de sortie du Fauteuil Roulant Manuel (FRM), est traumatisant pour les membres supérieurs. L’évaluation biomécanique du caractère traumatisant d’un mouvement nécessite d’en mesurer les composantes cinématiques et dynamiques. À…, The lateral transfer of a paraplegic person is defined as the movement of access or exit from the Manual Wheelchair (MW). This transfer is known to be traumatic for upper limbs. The biomechanical evaluation of the traumatic character of a movement requires the measurement of kinematic and dynamic…

Prise en compte des réglages du fauteuil roulant manuel (FRM) et de la position du sujet dans la modélisation de la stabilité du système {Sujet + FRM}

Philippe Vaslin, Touhami Haytem Ben, Arnaud Faupin, François-Xavier Lepoutre

Les réglages du FRM ont une grande importance sur les efforts produits par l'utilisateur pour se déplacer. Ils jouent aussi sur la stabilité du système {Sujet + FRM}, sachant que la posture du sujet a une influence prédominante sur ce paramètre. La stabilité du système est conditionnée par les…

Effects of Visual Context upon Functional Connectivity during Observation of Biological Motions

Magaly Hars, Mélany Hars, Cornelis J Stam, Claire Calmels

The aim of this study was to examine brain responses, in particular functional connectivity, to different visual stimuli depicting familiar biological motions. Ten subjects actively observed familiar biological motions embedded in point-light and video displays. Electroencephalograms were recorded…

Assessment of Transportation System Resilience

Simon Enjalbert, Frédéric Vanderhaegen, Marianne Pichon, Kiswendsida Abel Ouedraogo, Patrick Millot

A transportation system like tramway or train is a system in which the functions of the human and the machine are interrelated and necessary for the operation of the whole system according to Human–Machine System (HMS) definition. Both human and machines are sources of system reliability and causes…

Determination of pre-impact occupant postures and analysis of consequences on injury outcome. Part I: A driving simulator study

Audrey Hault-Dubrulle, Frederic Robache, Marie-Pierre Pacaux-Lemoine, Herve Morvan

This paper considers pre-impact vehicle maneuvers and analyzes the resulting driver motion from their comfort seating position. Part I of this work consists of analyzing the driver behavior during a crash. The study is conducted using the LAMIH driving simulator and involves 76 participants. The…

How the ankle joint angle alters the antagonist and agonist torques during maximal efforts in dorsi- and plantar flexion

M. Billot, E. M. Simoneau, Yves Ballay, Hoecke J. Van, A. Martin

The aim of this study was to assess, via an EMG bio-feedback method, the ankle joint angle effect on the agonist and antagonist torques in plantar- (PF) and dorsi-flexion (DF). The isometric PF and DF maximal voluntary contractions (MVCs) torques were measured simultaneously with surface EMG…

A Benefit/Cost/Deficit (BCD) model for learning from human errors

Frédéric Vanderhaegen, Stéphane Zieba, Simon Enjalbert, Philippe Polet

This paper proposes an original model for interpreting human errors, mainly violations, in terms of benefits, costs and potential deficits. This BCD model is then used as an input framework to learn from human errors, and two systems based on this model are developed: a case-based reasoning system…

How to characterize the regularity of surface topographies?

Gildas Guillemot, Maxence Bigerelle, Jérôme Antoni, K. Anselme

In this paper, a new parameter is proposed to characterize the regularity of a surface topography. The regularity of the surface with scaling invariance both in amplitude and position allows us to quantify the organization of surfaces by a number lying between 0 and 100%. This parameter is used to…
