Smoothed finite element method implemented in a resultant eight-node solid-shell element for geometrical linear analysis

Xavier J-G Elie-Dit-Cosaque, Augustin Gakwaya, Hakim Naceur

A smoothed finite element method formulation for the resultant eight-node solid-shell element is presented in this paper for geometrical linear analysis. The smoothing process is successfully performed on the element mid-surface to deal with the membrane and bending effects of the stiffness matrix...

Robust Observer Design of Tire Forces in Heavy Duty Vehicles

Hocine Imine, Omar Khemoudj, Mohamed Djemai, Krishna Busawon

This paper presents a robust observer design methodology to estimate tire forces in heavy-duty vehicles. The proposed methodology uses low-cost sensors and observer-based numerical differentiators. In addition to the already available sensors, low-cost sensors from the CAN bus are employed to get...

Fault detection and isolation for a multi-cellular converter based on sliding mode observer

Hicham Meziane, Cécile Labarre, Sanda Lefteriu, Michael Defoort, Mohamed Djemai

This paper presents a model-based approach for the fault diagnosis of three-cell power converters. The goal is to design a fault detection and isolation (FDI) scheme which diagnoses parametric and discrete faults. Parametric faults are characterized by abnormal changes in the capacitor value...

Nonlinear Observer for Autonomous Switching Systems with Jumps

Jean-Pierre Barbot, Mohamed Djemai, Noureddine Manamanni

This work deals with nonlinear observer synthesis for a particular class of hybrid dynamic systems (HDS): autonomous switching systems with jumps. The jumps can result from the system’s dynamics or from the diffeomorphism, which makes it possible to lead the system to an observability canonical...

Effects of robotic gait rehabilitation on biomechanical parameters in the chronic hemiplegic patients, Effets de la rééducation robotisée à la marche sur les paramètres biomécaniques de la marche chez des patients hémiplégiques chroniques

Laura Wallard, Gilles Dietrich, Yves Kerlirzin, Jonathan Bredin

Hemiplegia is a more or less complete loss of hemibody voluntary motricity following a brain injury, usually resulting in alterations of the locomotor system with persistent disorders of movement and posture. We were interested in studying the gait pattern called "stiff knee gait" with..., L’hémiplégie est une perte plus ou moins complète de la motricité volontaire d’un hémicorps suite à une lésion cérébrale, entraînant généralement des altérations de l’appareil locomoteur avec des troubles persistants du mouvement et de la posture. Nous nous sommes intéressés, pour cette étude, au...

Different surface sensing of the cell body and nucleus in healthy primary cells and in a cancerous cell line on nanogrooves

Patricia Davidson, Maxence Bigerelle, Gunter Reiter, Karine Anselme

Cancer cells are known to have alterations compared to healthy cells, but can these differences extend to the way cells interact with their environment? Here, the authors focused on the alignment on an array of grooves of nanometer depth using two cell types: healthy osteoprogenitor primary cells (...

A numerical study of the evolution of the blast wave shape in rectangular tunnels

David Uystepruyst, François Monnoyer de Galland

When the explosion of condensed materials occurs in square or circular cross-section tunnel, the subsequent blast wave reveals two patterns: three-dimensional close to the explosive charge and one-dimensional far from the explosion. Pressure decays for these two patterns have been thoroughly...

Observability and Observer Design of Partially Observed Petri Nets

Fayssal Arichi, Petreczky Mihaly, Mohamed Djemai, Brahim Cherki

This paper investigates observability and observer design of partially observed Petri nets (POPN). By using methods for descriptor systems, two major contributions are presented. First, a novel algebraic condition for POPN observability is presented. Second, an asymptotic observer is constructed...
