Tabu Search for a Parallel-Machine Scheduling Problem with Job Rejection, Inventory Penalties and Periodic Maintenance.

Hanane Krim, Nicolas Zufferey, Jean-Yves Potvin

We consider in this work a bicriteria scheduling problem on two different parallel machines with a periodic preventive maintenance policy. The two objectives considered involve minimization of job rejection costs and weighted sum of completion times. They are handled through a lexicographic…

Vehicles Tracking by Combining Convolutional Neural Network Based Segmentation and Optical Flow Estimation

Tuan-Hung Vu, Jacques Boonaert, Sebastien Ambellouis, Abdelmalik Taleb-Ahmed

Object tracking is an important proxy task towards action recognition. The recent successful CNN models for detection and segmentation, such as Faster R-CNN and Mask R-CNN lead to an effective approach for tracking problem: tracking-by-detection. This very fast type of tracker takes into account…

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…

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.…

Observer-based output feedback consensus protocol for double-integrator multi-agent systems under intermittent sampled position measurements

Dylan Poulsen, Michael Defoort, Mohamed Djemai

This paper deals with the leader-follower consensus problem for double-integrator multi-agent systems using sampled position data information. An observer-based output feedback controller is designed to study this problem while taking into account intermittent sensor failures. The non-uniformity…

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…

Distributed global actuator fault-detection scheme for a class of linear multi-agent systems with disturbances

Anass Taoufik, Michael Defoort, Mohamed Djemai, Krishna Busawon, Juan Diego Sanchez-Torres

This paper proposes a distributed methodology for the detection of actuator faults in a class of linear multi-agent systems in the presence of disturbances. A cascade of fixed-time observers is introduced to give an exact estimate of the global system state for each agent whereby the convergence…

Energetic valourisation of waste tyres by pyrolysis: catalyst effect on tyres derived oil and gases

Hiba Rejeb, Emna Berrich, Mohamed Hachemi Chahbani, Fethi Aloui

In this paper, an experimental investigation is carried out to study the zeolite catalyst ZSM5 effects on pyrolysis tyres derived oil TDO and gases. Two percentages of zeolite catalyst have been chosen, i.e., 10% and 20%. Experiments were carried out in a semi-batch reactor under inert atmosphere.…
