Symmetry analysis for film boiling of nanofluids on a vertical plate using a nonlinear approach

Andriy A. Avramenko, Igor V. Shevchuk, Shaaban Abdallah, D.G. Blinov, Souad Harmand, Andrii I. Tyrinov

This paper focuses on developing a self-similar model to be used in modeling of transport processes of heat, momentum and concentration in a nanofluid at its stable film boiling over a vertical surface. Novelty of the model consists in finding self-similar forms of variables and differential…

State feedback stabilization of a class of uncertain nonlinear systems on non-uniform time domains

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

This paper deals with the stabilization problem for a class of uncertain nonlinear systems on non-uniform time domains. Some sufficient conditions are derived to design a state feedback controller for a class of uncertain nonlinear time-varying systems under vanishing perturbations. Using some…

Impact of spatial hindrance on sit-to-stand and exit strategies of low mobility passengers

François Gabrielli, Ciska Molenaar, Mathias Blandeau, Philippe Pudlo

Aircraft cabin is considered as a hostile environment for low mobility passengers, especially around seat interaction. Improving air travel experience, and more specifically sit-tostand (STS) and seat exit could be done through digital human modeling, and there is a need for a first description of…

Modelling seated postural stability for complete spine cord injury

Mathias Blandeau, Thierry-Marie Guerra, Philippe Pudlo, François Gabrielli, Víctor Estrada Manzo

This paper introduces a modelling approach to investigate seated postural stability for subject suffering a complete spine cord injury (SCI). A mechanical model, variation of the double inverted pendulum, is used to represent a subject in the sagittal plane moving back and forth his uppers limbs…

Hand use during the lift phase of parallel sitting transfers of two spinal cord injured subjects

Ciska Molenaar, François Gabrielli, Mathias Blandeau, Philippe Pudlo

The purpose of this study is to list the shapes and locations used by both hands of spinal cord injured people during parallel transfers. Two spinal cord injured subjects were filmed while realizing 24 transfers each in a reconstructed aircraft cabin. An observation grid was developed to analyze…

Integration of Subjective and Objective Usability Evaluation Based on IEC/IEC 15939: A Case Study for Traffic Supervision Systems

Ahlem Assila, Káthia Marçal de Oliveira, Houcine Ezzedine

Usability evaluation for interactive systems is one of the greatest interests for Human-Computer Interaction community. To support this evaluation, several subjective and objective methods have been proposed and applied in academy and industry. In this context, usability evaluators usually work…

Simulation of continuum electrical conduction and Joule heating using DEM domains

Cédric Hubert, Damien Andre, Laurent Dubar, Ivan Iordanoff, Jean-Luc Charles

This paper proposes an original method to simulate the electrical conduction in continuums with the Discrete Element Method (DEM). The proposed method is based on the graphs theory applied to electrical resistance network, where the resistance between two discrete elements is estimated through the…

An integration of mixed VND and VNS: the case of the multivehicle covering tour problem

Manel Kammoun, Houda Derbel, Mustapha Ratli, Bassem Jarboui

The multivehicle covering tour problem (m-CTP) is a transportation problem with different kinds of locations, where a set of locations must be visited while another set must be close enough to planned routes. Given two sets of vertices V and W, where V represents the set of vertices that may be…

A reliable measure of footwear upper comfort enabled by an innovative sock equipped with textile pressure sensors

Alexis Herbaut, Emilie Simoneau-Buessinger, Franck Barbier, Francis Cannard, Nils Gueguen

Footwear comfort is essential and pressure distribution on the foot was shown as a relevant objective measurement to assess it. However, asperities on the foot sides, especially the metatarsals and the instep, make its evaluation difficult with available equipment. Thus, a sock equipped with…

On the mechanical characterization and modeling of polymer gel brain substitute under dynamic rotational loading

Benoît Fontenier, Audrey Hault-Dubrulle, Pascal Drazetic, Christian Fontaine, Hakim Naceur

The use of highly sensitive soft materials has become increasingly apparent in the last few years in numerous industrial fields, due to their viscous and damping nature. Unfortunately these materials remain difficult to characterize using conventional techniques, mainly because of the very low…
