A Method to Compute Efficient 3d Helicopters Flight Trajectories Based on a Motion Polymorph-Primitives Algorithm

Konstanca Nikolajevic, Nicolas Belanger, David Duvivier, Rabie Ben Atitallah, Abdelhakim Artiba

Finding the optimal 3D path of an aerial vehicle under flight mechanics constraints is a major challenge, especially when the algorithm has to produce real time results in flight. Kinematics models and Pythagorian Hodograph curves have been widely used in mobile robotics to solve this problematic....

Observer design for Takagi-Sugeno descriptor models: an LMI approach

Víctor Estrada Manzo, Thierry-Marie Guerra, Zsofia Lendek

This paper considers observer design for nonlinear descriptor systems. We propose approaches based on Takagi-Sugeno (TS) models. An extended estimation vector is used in order to keep the descriptor structure of the observer. The design conditions for this new type of observers are expressed as LMI...

Gestion de la diffusion info-communicationnelle d'un scanner de sûreté aéroportuaire innovant par les réseaux numériques, Managing the info-communicational dissemination of an innovative airport security scanner via the digital network

Michel Labour, Igor Crevits

Les réseaux numériques offrent de nombreuses opportunités de communiquer sur une innovation. L’analyse et la structuration des informations qui circulent s’avèrent déterminantes. Celles-ci reposent sur les travaux des Sciences de l’Information et de la Communication (SIC) et combinés à ceux de l’..., Digital networks offer numerous opportunities in communicating about a given innovation where the analysis and structuring of circulating information is a determining factor. This observation is based on studies conducted in the Information and Communicative Sciences and in the Decision Aiding...

New variable neighbourhood search based 0-1 MIP heuristics

Said Hanafi, Jasmina Lazic, Nenad Mladenovic, Christophe Wilbaut, Igor Crevits

In recent years many so-called matheuristics have been proposed for solving Mixed Integer Programming (MIP) problems. Though most of them are very efficient, they do not all theoretically converge to an optimal solution. In this paper we suggest two matheuristics, based on the variable...

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...

Design of a device to induce swirling flow in pipes: A rational approach

François Beaubert, Halldor Pálsson, Sylvain Lalot, Isabelle Choquet, Hadrien Bauduin

In this study, a rational approach is proposed to design a device for inducing swirling flow in heat exchanger pipes, for improved efficiency in the laminar regime. First, 2D computational fluid dynamics results lead to select, among four profiles, the blade profile with the most favorable lift to...

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...

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...
