Higher‐order sliding mode observer for estimation of tyre friction in ground vehicles

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort, Yeng Chai Soh

The estimation of friction coefficient for a vehicle when it traverses on different surfaces has been an important issue. In this work, the longitudinal vehicle dynamics, the torsional tyre dynamics and the non-linear LuGre friction dynamics are integrated to model the quarter vehicle dynamics. The…

A comparison of rigid registration methods for prostate localization on CBCT and the dependence on rectum distension

Christine Boydev, David Pasquier, Foued Derraz, Laurent Peyrodie, Abdelmalik Taleb-Ahmed, Jean-Philippe Thiran

We evaluated automatic three-dimensional intensity-based rigid registration (RR) methods for prostate localization on CBCT scans and studied the impact of rectum distension on registration quality. 106 CBCT scans of 9 prostate patients were used. Each one was registered to the planning computed…

Geometrical and material parameters to assess the macroscopic mechanical behaviour of fresh cranial bone samples

Audrey Auperrin, Rémi Delille, Denis Lesueur, Karine Bruyere, Catherine Masson, Pascal Drazetic

The present study aims at providing quantitative data for the personalisation of geometrical and 21 mechanical characteristics of the adult cranial bone to be applied to head FE models. A set of 351 22 cranial bone samples, harvested from 21 human skulls, were submitted to three-point bending tests…

Analysis of two-phase pressure drop fluctuations during micro-channel flow boiling

Yuan Wang, Khellil Sefiane, Zhengguo Wang, Souad Harmand

Two-phase pressure drop fluctuations during flow boiling in single micro-channel were experimentally investigated. Degassed FC-72 was tested in micro-channels with a hydraulic diameters of 571 μm, 762 μm and 1454 μm (the aspect ratio (Win/din) is 20, 20 and 10) at liquid mass fluxes of 11.2 kg m−2…

Automation-driver cooperative driving in presence of undetected obstacles

Boussaad Soualmi, Chouki Sentouh, Jean-Christophe Popieul, Serge Debernard

The work presented in this paper describes and discusses the principles of a haptic shared control between a human driver and an Electronic copilot (E-copilot) for a vehicle. The aim of the sharing control is to allow the driver to momentarily take control over the E-copilot without deactivating it…

Efficient hybrid optimization approach for emission constrained economic dispatch with nonsmooth cost curves

Samir Sayah, Abdellatif Hamouda, Abdelghani Bekrar

Power plants usually operate on the strategy of economic dispatch (ED) regardless of emissions produced. Environmental considerations have become one of the major management concerns. Under these circumstances, the alternative strategy of environmental/economic dispatch (EED) is becoming more and…

A simulation-based decision support system to prevent and predict strain situations in emergency department systems

Farid Kadri, Sondès Chaabane, Christian Tahon

The management of patient flow, especially the flow resulting from health crises in emergency departments (ED), is one of the most important problems managed by ED managers. To handle this influx of patients, emergency departments require significant human and material resources, but these are…

Opportunistic Data Services in Least Developed Countries: Benefits, Challenges and Feasibility Issues

Nicolas Anciaux, Luc Bouganim, Thierry Delot, Sergio Ilarri, Leïla Kloul, Nathalie Mitton, Philippe Pucheral

facilitator in establishing primary education, reducing mortality or supporting commercial initiatives in Least Developed Countries. The main barrier to the development of IT services in these regions is not only the lack of communication facilities, but also the lack of consistent information…

Liquid film evaporation enhancement in a vertical annulus with preheated air flow

Rym Ben Radhia, Souad Harmand, Jean-Pierre Corriou, Sadok Ben Jabrallah

The evaporation by mixed convection of a water film falling down the inner wall of a vertical annulus was studied numerically. The outer wall was assumed to be insulated and dry. A counter-current flow of preheated, dry air was blown between two concentric cylinders. This air flow was preheated at…

Experimental investigation on the feasibility of heat pipe cooling for HEV/EV lithium-ion battery

Thanh-Ha Tran, Souad Harmand, Bernard Desmet, Sebastien Filangi

In this paper, the use of flat heat pipe as an effective and low-energy device to mitigate the temperature of a battery module designed for a HEV application was investigated. For this purpose, nominal heat flux generated by a battery module was reproduced and applied to a flat heat pipe cooling…
