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…

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…

Development of CBCT-based prostate setup correction strategies and impact of rectal distension

Christine Boydev, Abdelmalik Taleb-Ahmed, Foued Derraz, Laurent Peyrodie, Jean-Philippe Thiran, David Pasquier

Background: Cone-beam computed tomography (CBCT) image-guided radiotherapy (IGRT) systems are widely used tools to verify and correct the target position before each fraction, allowing to maximize treatment accuracy and precision. In this study, we evaluate automatic three-dimensional intensity-…

An innovative procedure for characterising a coupled elastoplastic damage model of behaviour using the Virtual Fields Method

Delphine Notta-Cuvier, Bertrand Langrand, Franck Lauro, Eric Markiewicz

The characterisation of material behaviour models can be challenging, especially when dealing with strongly non-linear constitutive laws. Classical procedures are restricted to the treatment of homogeneous mechanical fields. They can therefore not be applied after strain localisation and behaviour…

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…

Axisymmetric modeling of the thermal cooling, including radiation, of a circular glass disk

Norbert Siedow, Dominique Lochegnies, Fabien Béchet, Philippe Moreau, Hiroshi Wakatsuki, Nobuhiro Inoue

Achieving correct tempering in thin glass is very important to prevent undesired stress and breakage. Computer simulation can elucidate and control the tempering process. For semitransparent materials like glass, heat transfer by thermal radiation is substantial; for thick glass, it may dominate…

Revenue management for rail container transportation

Ioana Bilegan, Luce Brotcorne, Dominique Feillet, Yezekael Hayel

In this paper, we consider the revenue maximization problem of a rail freight transportation company or an intermodal marketing company selling freight transportation services. We propose a revenue management (RM) policy to dynamically accept transportation requests or reject them in favor of some…

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…

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…

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…
