Quantitative Evolution of WC-Co Cemented Carbide Tool Surface during the Cold Forming of Steel Parts

Laurent Dubar, Colin Debras, Mirentxu Dubar, André Dubois

The present paper investigates the evolution of the WC grain size and morphology with the number of produced parts. Four reduction dies used in cold forward extrusion of steel are taken from the production line: a brand new die and three dies which have respectively produced 100.000, 150.000 and…

Geometrically nonlinear bending analysis of functionally graded beam with variable thickness by a meshless method

Jun Lin, Jiao Li, Yanjin Guan, Guoqun Zhao, Hakim Naceur, Daniel Coutellier

Geometrically nonlinear bending deformation of Functionally Graded Beams (FGBs) with variable thickness is simulated by a meshless Smoothed Hydrodynamic Particle (SPH) method. The material properties of FGB is assumed to be varied smoothly in the thickness according to exponent-law distribution. To…

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…

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…

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…

An effective and distributed particle swarm optimization algorithm for flexible job-shop scheduling problem

Maroua Nouiri, Abdelghani Bekrar, Abderrazak Jemai, Smail Niar, Ahmed Chiheb Ammari

Flexible job-shop scheduling problem (FJSP) is very important in many research fields such as production management and combinatorial optimization. The FJSP problems cover two difficulties namely machine assignment problem and operation sequencing problem. In this paper, we apply particle swarm…

Gain-scheduled static output feedback control for saturated LPV systems with bounded parameter variations

Tran Anh-Tu Nguyen, Philippe Chevrel, Fabien Claveau

This paper presents a new design method for gain-scheduled static output feedback (SOF) controllers of saturated LPV (linear parameter varying) systems. Our solution is based on a special SOF scheme in conjunction with specific congruence transformations. The regional design is established through…

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…

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…
