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…

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…

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-…

Human Reliability Assessment under Uncertainty – Towards a Formal Method

Subeer Rangra, Mohamed Sallak, Walter Schön, Frédéric Vanderhaegen

Humans are and will remain one of the critical constituents of a technological system. The study of human factors is a broad domain with equally varying applications. Furthermore, with the advent of new technologies in safety-critical systems there is always a need to ensure system safety and…

Void Fraction Influence Over Aqueous Foam Flow: Wall Shear Stress and Core Shear Evolution

Rogelio Chovet, Fethi Aloui

In this study, the two main transport characterization problems of the foam flow are studied: foam flow stability, through the evolution of the velocity at the core of the foam, and rheology, with the study of the wall shear stress over the lateral walls, for different void fractions. The same…

An Analysis of Driver's Avoiding Maneuver in a Highly Emergency Situation

Makoto Itoh, Marie-Pierre Pacaux-Lemoine, Frédéric Robache, Hervé Morvan

This paper discusses driver’s emergency avoiding behavior while he or she is driving a car in a rural area.Based on behavioral data obtained from an experiment conducted in France with a high-ﬁdelity driving simulator, theauthors analyzed the driver behavior just before the collision. The results…

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.…

Identification of lubrication regime on textured surfaces by multi-scale decomposition

Cédric Hubert, Krzysztof Kubiak, Maxence Bigerelle, André Dubois, Laurent Dubar

This paper focuses on the analysis of surfaces resulting from thickness reduction of aluminium strips, provided with lubricant reservoirs, and deformed with different lubricant viscosities and drawing velocities, by a specific experimental drawing process. During reduction, the lubricant is…
