Adaptive layout for operating theatre in hospitals: different mathematical models for optimal layouts

Abdelahad Chraibi, Said Kharraja, Ibrahim H. Osman

The adaptive layout for operating theatre (ALOT) problem in hospitals seeks to determine the ‘most efficient’ layout placement of a set of health-care operating facilities, corridors and elevators in a designated area subject to a set of constraints on professional standards. Such standards include...

Large-scale fractional-order systems: stability analysis and their decentralized functional observers design

Yassine Boukal, Mohamed Darouach, Michel Zasadzinski, Nour-Eddine Radhy

This study concerns the stability analysis of linear large-scale fractional-order systems and its functional observers design. First, based on the diffusive representation of the fractional-order derivative and the indirect Lyapunov approach, the stability of large-scale fractional-order...

LIDAR and Stereo-Camera fusion for reliable Road Extraction

Mohammed Yazid Lachachi, Mohamed Ouslim, Abdelmalik Taleb-Ahmed, Smail Niar

his paper presents a novel approach that combines LIDAR and Stereo-cameras. First, a stereo camera is used to guide the extraction of road surface points from a 3D point cloud obtained by a LIDAR. Then, the number of points is reduced based on their elevation and illumination invariant colors....

CFD characterization of a wet foam flow rheological behavior

Heni Dallagi, Ramla Gheith, Ahmad Al Saabi, Christine Faille, Wolfgang Augustin, Thierry Benezech, Fethi Aloui

In some industrial processes, aqueous foams flow presents an important phase of the process, whereas, they cause pressure drop when designing and dimensioning systems. Identifying the different rheological parameters of foam flow is an interest key to understanding the interfacial phenomena....

Consensus of Double-Integrator Multi-Agent Systems Using Decentralized Model Predictive Control

Pipit Anggraeni, Michael Defoort, Mohamed Djemai, Aries Subiantoro, Abdul Muis

This paper studies the consensus for a group of agents which have a discrete-time double-integrator dynamics. To solve this problem, a Model Predictive Control (MPC) scheme is introduced. The proposed control protocol is decentralized and is designed by combining graph theory with a predictive...

Fixed-Time Tracking Control of Chained-form Nonholonomic System with External Disturbances

Pipit Anggraeni, Michael Defoort, Mohamed Djemai, Zongyu Zuo

This paper studies the fixed-time tracking problem for chained-form nonholonomic systems under matched external disturbances. The proposed method is to construct a tracking controller such that the tracking errors converge to zero for any arbitrary initial tracking error at fixed-time. First of all...

Wetting and evaporation of nanosuspension droplets, Mouillage et évaporation de gouttelettes de nanosuspensions

Maryam Maria Parsa

Evaporation of liquid droplets containing non-volatile solutes is an omnipresent phenomenon in daily life, e.g., coffee stains on solid surfaces. The study of pattern formation of the particles left after the evaporation of a sessile droplet has attracted the attention of many researchers during..., L’évaporation de gouttes de liquides contenant des particules non volatiles représente un phénomène largement présent dans la vie quotidienne, à l’image des traces laissées par le marc de café après séchage. L’étude de la morphologie des dépôts de particules présente un grand intérêt dans les...

Active Side Shafts Torsion Damping Control for Hybrid Electric Vehicles

Walter Lhomme, Florian Tournez, Sebastien Delprat, Sebastien Paganelli

Hybrid electric vehicles generally use an internal combustion engine and one or several electric drives. Optimization-based energy management strategies computes a power split between both the engine and the machine to minimize the fuel consumption. Nevertheless, the driving comfort is not taken...
