Espace de Minkowski-Lorentz et des sphères : un état de l'art

Jean-Paul Becar, Lucie Druoton, Laurent Fuchs, Lionel Garnier, Rémi Langevin, Géraldine Morin

Dans cet article, nous faisons une présentation de l'espace de Minkowski-Lorentz généralisant, à Ê 5 l'espace utilisé dans la théorie de la relativité. Cet espace de dimension 5 contient un paraboloïde de dimension 3 et isométrique à l'espace affine euclidien usuel E 3 , l'...

Context-based evaluation of mobile knowledge management systems

Emna Ben Ayed, Christophe Kolski, Houcine Ezzedine

The technological revolution has been accompanied with the appearance of mobile systems. Mobile Knowledge Management Systems (KMS) which introduce a new style of managing organizations using mobile devices, are used in different contexts of use. So, a context based evaluation of such systems...

Differences between expert and novice gymnasts performance of a counter movement forward in flight on uneven bars

Aurore Huchez, Diane Haering, Patrice Holvoët, Franck Barbier, Mickael Begon

This study investigated the different strategies exhibited by expert and novice gymnasts in counter movement forward in flight on uneven bars. Eleven gymnasts performed three trials connected with a kip to support. The gymnasts were divided into two groups according to their ability to connect: six...

Numerical simulation of the flow through the blades of a swirl generator

Manel Wannassi, François Monnoyer de Galland

This paper aims at analyzing the dynamics behavior of the flow generated by blade swirlers. Three-dimensional calculations are carried out for different Reynolds numbers and blade angles (θ = 20◦, 30◦, and 45°). Flow field characteristics within the swirler and in the outgoing jet are examined in...

Control synthesis for polynomial discrete-time systems under input constraints via delayed-state Lyapunov functions

J. L. Pitarch, Jimmy Lauber, Thierry-Marie Guerra, Antonio Sala

This paper presents a discrete-time control design methodology for input-saturating systems using a Lyapunov function with dependence on present and past states. The approach is used to bypass the usual difficulty with full polynomial Lyapunov functions of expressing the problem in a convex way....

Mirror Effect Based Learning Systems to Predict Human Errors - Application to the Air Traffic Control

Frédéric Vanderhaegen

Resilience of a human-machine system such as air traffic control relates to the successful control of its instability. This instability can be due to the temporal variability or the magnitude of functional task demands, and this may provoke human error occurrence. The paper proposes an original...
