A Distributed Observer-Based Cyber-Attack Identification Scheme in Cooperative Networked Systems under Switching Communication Topologies

Anass Taoufik, Michael Defoort, Krishna Busawon, Laurent Dala, Mohamed Djemai

This paper studies an approach for detecting cyber attacks against networked cooperative systems (NCS) that are assumed to be working in a cyber-physical environment. NCS are prone to anomalies both due to cyber and physical attacks and faults. Cyber-attacks being more hazardous given the...

A query-based framework to improve BIM multi-domain collaboration

Sattler Léa, Samir Lamouri, Robert Pellerin, Virginie Fortineau, Mohammed Larabi, Thomas Maigne

Although BIM has been widely adopted in the past decade, multi-domain collaboration through BIM is still a struggle, involving different barriers such as trade-specific semantic definitions, data-schemas heterogeneousness and low levels of digital cooperation in AEC. After a brief review of...

Control of an automated wheelchair

Michael Gray, Thierry-Marie Guerra, Sebastien Delprat, Sami Mohammad

Due to the world's aging population, the development of affordable and easy to use wheelchairs is becoming a priority. In this study, the control of an automated wheelchair is proposed. The model equations are derived from the Euler-Lagrange equations, then a descriptor model is formulated....

Liquid–solid two-phase jet in a turbulent crossflow: Experiments and simulations

Charlène Octau, Talib Dbouk, Michel Watremez, Damien Méresse, Marc Lippert, Jesse Schiffler, Laurent Keirsbulck, Laurent Dubar

Compared to single-liquid and liquid–liquid jets in crossflow (JICF), liquid–solid two-phase JICF is rarely studied. An experimental setup has been developed to investigate a vertical jet of liquid–solid mixture in water turbulent crossflow at Re≈2.2·104 over 4 s period. Rigid micro particles were...

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...

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....

Characterization of particulate matter emissions in urban train braking - An investigation of braking conditions influence on a reduced-scale device

Charlène Octau, Damien Méresse, Michel Watremez, Jesse Schiffler, Marc Lippert, Laurent Keirsbulck, Laurent Dubar

The particulate matter emissions related to the braking of railway rolling stock are investigated using a reduced scale braking device. Samples of organic materials and cast iron discs are tested for different nominal contact pressures and disc surface temperatures, representative of real...

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...

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...
