Correlation modeling between process condition of sandblasting and surface texture: A multi-scale approach

Hsin Shen Ho, Maxence Bigerelle, Renald Vincent, Raphaël Deltombe

In the present study, the influence of sandblasting condition (working pressure) on surface texture is modeled, relying on a multi-scale approach and statistical analysis. To improve the correlation modeling between the process condition and surface texture, special effort is made to identification…

Dynamic modelling of the expansion cylinder of an open Joule cycle Ericsson engine: A bond graph approach

Marie Creyx, Eric Delacourt, Céline Morin, Bernard Desmet

A dynamic model using the bond graph formalism of the expansion cylinder of an open Joule cycle Ericsson engine intended for a biomass-fuelled micro-CHP system is presented. Dynamic phenomena, such as the thermodynamic evolution of air, the instantaneous air mass flow rates linked to pressure drops…

Heat exchanger identification by using iterative fuzzy observers

Sylvain Lalot, Oddgeir Guðmundsson, Halldor Pálsson, Ólafur Pétur Pálsson

The principle of fuzzy observers is first illustrated on a general example: the determination of the two parameters of second order systems using a step response. The set of equations describing the system are presented and it is shown that accurate results are obtained, even for a high level of…

Time pressure and regulations on hospital-in-the-home (HITH) nurses: An on-the-road study

Stéphanie Coeugnet, Justine Forrierre, Janick Naveteur, Catherine Dubreucq, Françoise Anceaux

This study investigated both causal factors and consequences of time pressure in hospital-in-the-home (HITH) nurses. These nurses may experience additional stress from the time pressure they encounter while driving to patients' homes, which may result in greater risk taking while driving. From…

Differential impact of visual feedback on plantar- and dorsi-flexion maximal torque output

Anis Toumi, Jennifer Jakobi, Emilie Simoneau-Buessinger

The effect of visual feedback on enhancing isometric maximal voluntary contractions (MVC) was evaluated. Twelve adults performed plantar-flexion and dorsi-flexion MVCs in 3 conditions (no visual feedback, visual feedback, and visual feedback with target). There was no significant effect of visual…, Dans cet article, on évalue l’effet de la rétroaction visuelle sur l’amélioration de la contraction isométrique volontaire maximale (« MVC »). Douze adultes effectuent des MVC au moyen de flexions plantaires et de flexions dorsales dans trois conditions : sans rétroaction visuelle, avec rétroaction…

Towards Lean Healthcare: Implementation of operations excellence in public hospitals, L’excellence hospitalière, ou la mise en œuvre de l'excellence opérationnelle dans le monde hospitalier

Virginie Fortineau, Samir Lamouri, Guillaume Eckerlein, André Rieutord, Niccolo Curatolo

In the 80's, the Lean Production System urged industrial companies to « think different » the operational system. Nowadays, the public hospital is facing difficulties that make revelant a global organisationnal transformation. contributions involving Lean applications in healthcare exist, but…

GRASP-based heuristic algorithm for the multi-product multi-vehicle inventory routing problem

Oualid Guemri, Abdelghani Bekrar, Bouziane Beldjilali, Damien Trentesaux

In this paper, we introduce an improved Greedy Randomized Adaptive Search Procedure (GRASP) based heuristic for the multi-product multi-vehicle inventory routing problem (MMIRP). The inventory routing problem, which combines the vehicle-routing problem and the inventory control decisions, is one of…

Energetic and Exergetic Analysis of a Heat Exchanger Integrated in a Solid Biomass-Fuelled Micro-CHP System with an Ericsson Engine

Marie Creyx, Eric Delacourt, Céline Morin, Sylvain Lalot, Bernard Desmet

A specific heat exchanger has been developed to transfer heat from flue gas to the working fluid (hot air) of the Ericsson engine of a solid biomass-fuelled micro combined heat and power (CHP). In this paper, the theoretical and experimental energetic analyses of this heat exchanger are compared.…

Experimental investigations for uncertainty quantification in brake squeal analysis

Alexandre Renault, Franck Massa, Bertrand Lallemand, Thierry Tison

The aim of this paper is to improve the correlation between the experimental and the numerical prediction of unstable frequencies for automotive brake systems considering uncertainty. First, an experimental quantification of uncertainty and a discussion analysing the contributions of uncertainty to…

Carpal height and postoperative strength after proximal row carpectomy or four-corner arthrodesis: Clinical, anatomical and biomechanical study, Hauteur du carpe et force postopératoire après résection de la rangée proximale ou arthrodèse des quatre os médiaux avec scaphoïdectomie : étude clinique, anatomique et biomécanique

Pascale Laronde, Nicolas Christiaens, Aurélien Aumar, Christophe Chantelot, Christian Fontaine

Proximal row carpectomy (PRC) and four-corner arthrodesis (4CA) are the two most commonly performed surgical procedures to treat wrist arthritis. Postoperative strength is one of the criteria for choosing between the two techniques. Some authors believe that strength is correlated with residual…, Résection de la rangée proximale du carpe (RRPC) et arthrodèse des quatre os médiaux (A4O) avec scaphoïdectomie sont des interventions couramment pratiquées dans la prise en charge de l’arthrose de poignet. La force postopératoire est un critère de choix entre ces deux techniques. Pour certains,…
