2.2. La Maîtrise universitaire en sciences de l’éducation Formation des adultes vise essentiellement à développer chez tous les étudiants une double capacité d’analyse et d’intervention dans le champ de la formation des adultes. Le programme prend en compte la diversité qui caractérise ce champ de pratiques sociales ainsi que les métiers y afférant. Il s’appuie à cette fin sur la transmission d...

We consider the three-dimensional Schrödinger operator with constant magnetic field and bounded random electric potential. We investigate the asymptotic behaviour of the integrated density of states for this operator as the norm of the magnetic field tends to infinity. Résumé On considère l’opérateur de Schrödinger tridimensionnel avec un champ magnétique constant et un potentiel électrique alé...

In the classical approach to elasticity problems, the components of the displacement field are the primary unknowns. In an “intrinsic” approach, new unknowns with more physical or geometrical meanings, such as a strain tensor field or a rotation field for instance, are instead taken as the primary unknowns. We survey here recent progress about the mathematical analysis of such methods applied t...

Dynamical hysteresis is a phenomenon which arises in ferromagnetic systems below the critical temperature as a response to adiabatic variations of the external magnetic field. We study the problem in the context of the mean-field Ising model with Glauber dynamics, proving that for frequencies of the magnetic field oscillations of order N−2/3, N the size of the system, the “critical” hysteresis ...

We review research on geomagnetic pulsations carried out using magnetic field measurements from the CHAMP lowEarth-orbit (LEO) satellite and ground-based stations in South Africa and Hungary. The high quality magnetic field measurements from CHAMP made it possible to extract and clearly resolve Pi2 and Pc3 pulsations in LEO satellite data. Our analyses for nighttime Pi2 pulsations are indicativ...

Overview The COSMIC Data Analysis and Archival Center (CDAAC) at UCAR has processed radio occultation data from the GPS/MET, CHAMP, and SAC-C missions in post-processing and a near real time mode of operation for CHAMP. The GPS data processing at the CDAAC is performed with the Bernese v5.0 software package. The COSMIC mission requirement for LEO velocity uncertainty is 0.1 mm/s 3D rms. The rec...

CHAMP (CHAllenging Minisatellite Payload) and GRACE (Gravity Recovery And Climate Experiment) formed a satellite configuration for precise atmospheric sounding during the first activation of the GPS (Global Positioning System) radio occultation experiment aboard GRACE on 28 and 29 July 2004. 338 occultations were recorded aboard both satellites, providing globally distributed vertical profiles ...

-A mobile ad hoc network is an autonomous system of infrastructureless, multihop wireless mobile nodes. Reactive routing protocols perform well in such an environment due to their ability to cope quickly against topological changes. In this paper, we propose a new routing protocol called Caching and Multipath (CHAMP) Routing Protocol. CHAMP uses cooperative packet caching and shortest multipath...
