: Une étude de trajectoires scolaires et professionnelles en Colombie-Britannique
2015
En ligne sur : http://www.cereq.fr/index.php/content/download/7936/71610/file/Relief50.pdf; National audience; Bien que le système éducatif donne beaucoup d'options aux étudiants, il y a des avantages et désavantages inhérents aux différents types de trajectoires. Les études, souvent chères, obligent les étudiants à choisir entre deux options : travailler pendant des études prolongées ou faire un prêt étudiant.Mais les deux options présentent des risques. Après que les individus soient entrés dans le marché du travail, ils ont toujours la possibilité de se réinscrire dans l'enseignement supérieur pour obtenir un diplôme plus élevé. La flexibilité donne de la liberté, mais une liberté limité…
Actes des 3èmes Rencontres DGEFP
2022
International audience; Cet ouvrage rend compte des travaux du Céreq présentés lors des 3èmes Rencontres DGEFP-Céreq qui ont eu lieu en Juin 2021. Les Rencontres DGEFP-Céreq ont pour objectif d’éclairer de façon renouvelée les questions relatives à l’impact des politiques de formation sur le comportement des entreprises et de leurs salariés. Ces rencontres sont un espace privilégié pour la diffusion des travaux de recherche et leur mise en débat.

Nonadiabatic dynamics in strongly driven diffusive Josephson junctions
2019
By measuring the Josephson emission of a diffusive Superconductor-Normal metal-Superconductor (SNS) junction at a finite temperature we reveal a non-trivial sensitivity of the supercurrent to microwave irradiation. We demonstrate that the harmonic content of the current-phase relation is modified due to the energy redistribution of quasiparticles in the normal wire induced by the electromagnetic field. The distortion originates from the phase-dependent out-of-equilibrium distribution function which is strongly affected by the ac-response of the spectral supercurrent. For phases close to $\pi$, transitions accross the Andreev gap are dynamically favored leading to a supercurrent reduction. T…

Experimental Researches Regarding Strain Measurement of Incrementally Formed Sheet Metal Parts Done Using an Industrial Robot
2014
This paper aims to provide results regarding the measurement of the strains in the material of sheet metal parts which have been incrementally formed. The incremental forming of the steel sheets has been performed with the aid of a KUKA KR 6 industrial robot on a specially constructed stand, and the measurement of the strains has been done using ARAMIS optical measurement system. The trajectory of the forming punch which is attached to the robot was designed using CATIA V5 and the movements of the robot were designed and simulated in DELMIA software. DELMIA generated the program code needed for the robot to execute the desired movements in order to form the sheet metal parts.
An adaptive control law for robotic manipulator without velocity feedback
2003
In this paper, a new adaptive control law is designed for robotic manipulators, based on the use of reference velocities instead of the actual ones and feedback signals generated from position errors. The law in question is suitable for trajectory tracking and positioning tasks. Its peculiarities are implementation without velocity measurements and estimation, high signal-to-noise ratio in control torques and absence of parameter drift in positioning tasks. Experimental tests are shown with the aim to confirm the validity of the control law and to illustrate its actual effects on the behaviour of the system.
