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…

Evaluation and qualification of mobile application quality.

Rudy Bisiaux, Mikael Desertot, Sylvain Lecomte, Dorian Petit

Development of mobile applications has previously encountered, and still encounters, challenges related to the specificity of the mobile world. The usual rules of software engineering tend not to respond to certain mobile development issues. In this paper, we identify and address the challenges of…

Numerical Study of the Toughness of Complex Metal Matrix Composite Topologies

Julie Lemesle, Cédric Hubert, Maxence Bigerelle

Fracture toughness tests (compact tension) of a dual material composed of a structured Metal Matrix Composite (MMC) (martensitic steel and titanium carbides, named MS-TiC) surrounded by martensitic steel (MS) are simulated with a Discrete Elements Model (DEM) developed with the GranOO Workbench.…

Review on the performances, foaming and injection molding simulation of natural fiber composites

Jianghu Zhan, Jiao Li, Guilong Wang, Yanjin Guan, Guoqun Zhao, Jun Lin, Hakim Naceur, Daniel Coutellier

Recently, natural fiber becomes an alternative to the synthetic fiber for the composites used in aerospace, automotive, sports, packaging and so on, due to its inherent characteristics like biodegradablity, renewablity, high-specific strength and specific modulus. However, there are still many…

Mechanical properties of WC/Co-CNT HVOF sprayed coatings

Mariana H. Staia, Alberto Mejias, José Gregorio La Barbera-Sosa, Eli Saúl Puchi-Cabrera, C. Villalobos-Gutiérrez, Yucelys Yessenia Santana de La Barbera, Alex Montagne, Alain Iost, M. A. Rodríguez

Coatings based on WC–12Co, with and without the reinforcement of carbon nanotubes (CNTs) have been deposited by means of the HVOF thermal spraying technique on a SAE 1020 steel substrate. The aim of the present study is to evaluate in detail the influence of the 36 h milling time on both feedstock…

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…

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…
