Correction to “Unknown input observer design for linear fractional-order time-delay systems” and a new enhanced LMI condition

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

This note considers the work entitled “Unknown Input Observer Design for Linear Fractional-Order Time-Delay Systems”. In the above paper [1], the authors gave the existence conditions of such observer, then based on the fractional order Lyapunov stability approach, a sufficient condition for the...

Modeling the viscoplastic flow behavior of a 20MnCr5 steel grade deformed under hot-working conditions, employing a meshless technique

Juan Carlos Álvarez-Hostos, Alfonso D. Bencomo, Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Laurent Dubar

The present work has been conducted in order to develop a novel approach to predict the inhomogeneous flow of a 20MnCr5 steel during an axisymmetric hot compression test, by using the element-free Galerkin (EFG) method under a differential constitutive description. The governing equations have been...

Decentralized motion planning and scheduling of AGVs in FMS

Guillaume Demesure, Michael Defoort, Abdelghani Bekrar, Damien Trentesaux, Mohamed Djemai

In this paper, decentralized motion planning and scheduling of automated guided vehicles (AGVs) in a flexible manufacturing system (FMS) is proposed. A motion planner is combined with a scheduler allowing each AGV to update its destination resource during navigation in order to complete the...

Friction and Wear in Metal Forming: 25 Years at LAMIH UMR CNRS 8201

Laurent Dubar, André Dubois, Mirentxu Dubar

Since the beginning of the 90’s, research activities focused on friction and wear in metal forming have been developed at the LAMIH UMR CNRS 8201 in Valenciennes. Specific methodologies have been designed to optimize a given forming process (bulk forming process or sheet forming process). These...

Video-processing-based system for automated pedestrian data collection and analysis when crossing the street

Nabila Mansouri, Eric Watelain, Yousra Ben Jemaa, Cina Motamed

Computer-vision techniques for pedestrian detection and tracking have progressed considerably and become widely used in several applications. However, a quick glance at the literature shows a minimal use of these techniques in pedestrian behavior and safety analysis, which might be due to the...

Gait‐based human age classification using a silhouette model

Nabila Mansouri, Mohammed Aouled Issa, Yousra Ben Jemaa

Age estimation at a distance has potential applications including visual surveillance and monitoring in public places. Far from the camera, image resolution is significantly degraded. In fact, age estimation using classical methods such as face is not reliable. Given that gait is very sensitive to...

Mathematical programming models for scheduling in a CPU/FPGA architecture with heterogeneous communication delays

Abdessamad Ait El Cadi, Omar Souissi, Rabie Ben Atitallah, Nicolas Belanger, Abdelhakim Artiba

This paper deals with the mathematical modelling of a scheduling problem in a heterogeneous CPU/FPGA architecture with heterogeneous communication delays in order to minimize the makespan, Cmax. This study was motivated by the quality of the available solvers for Mixed Integer Program. The proposed...

Designing a camera placement assistance system for human motion capture based on a guided genetic algorithm

Azeddine Aissaoui, Abdelkrim Ouafi, Philippe Pudlo, Christophe Gillet, Zine-Eddine Baarir, Abdelmalik Taleb-Ahmed

In multi-camera motion capture systems, determining the optimal camera configuration (camera positions and orientations) is still an unresolved problem. At present, configurations are primarily guided by a human operator’s intuition, which requires expertise and experience, especially with complex...

On Convective Heat Transfer and Flow Dynamics Through a Straight T-Bifurcating Channel

Abdelhak Lakehal, Nora Nait Bouda, Julien Pellé, Souad Harmand

Both experimental and numerical studies of a turbulent flow in a bifurcating channel are performed to characterize the dynamical behavior of the flow and its impact on the convective heat transfer on the sides of the branch. This configuration corresponds to the radial vents placed in the stator...
