Les « périphéries » sous contrôle : espaces portuaires et frontaliers. Introduction
1999
Comme l’indique son titre, cette partie nous entraîne sur les espaces frontaliers, dont certains sont aussi des espaces portuaires : deux études portent sur le Nord, deux autres sur les rivages de la Méditerranée (Marseille et les Alpes-Maritimes), la cinquième sur la Bretagne méridionale (Lorient). C’est un avantage de n’avoir à mettre en parallèle que trois espaces géographiques en cinq contributions, mais c’est aussi un manque pour le traitement du sujet de ne pas disposer d’autres points ...
Le contrôle des migrants en ville. Introduction
2015
L’intérêt de la question du contrôle des migrants en ville tient à l’importance de l’immigration dans la formation de la population urbaine, notamment de grandes villes comme Paris. La venue d’un grand nombre de personnes, originaires d’une province plus ou moins proche ou de l’étranger, pose aux autorités la question du contrôle d’une population qualifiée parfois de flottante, pour la partie qui ne s’intègre pas définitivement dans le milieu urbain. On sait combien, depuis Louis Chevalier, c...
On the Energy Efficiency of Dual Prime Mover Pump-Controlled Hydraulic Cylinders
2019
Abstract This paper concerns the energy efficiency of a special class of pump-controlled hydraulic cylinders utilizing two prime movers. The performance of such circuits has been studied previously motivated by their capability of providing an actuator stiffness similar to that of servo valve-controlled systems. This characteristic may improve performance and robustness in applications requiring feedback control. In this paper, the presence of losses similar to that of fluid throttling, in the sense that they occur even in the absence of component inefficiencies, are demonstrated for such circuits and shown to degrade the overall energy efficiency of the system. The conditions under which s…

Methods for Experimentally Determining Stiffness of a Multi-Axis Machining Centre
2019
This paper deals with global methods for experimentally determining the static stiffness of multi-axis machining centres. Different devices used for measuring deflection, in specific, are explored, where accuracy and usability are highlighted. The methods were tested on a 3-axis CNC milling machine, 2-axis trunnion table and a 6-DOF industrial robot.

Method for estimating combined controller, joint and link stiffnesses of an industrial robot
2014
In this paper a new combined local/global approach for estimating the combined stiffnesses of joints in anthropomorphic robots is presented. The stiffness of each joint is a combination of several effects: i) stiffness of the links, ii) stiffness of joint bearings and gears and iii) stiffness of the position control loops given by the individual axis controller gains in the controller software. Experimental results are presented for an ABB IRB6600 industrial robot using measurements from a FARO Xi laser tracker and an ATI Omega160 force/torque sensor. The results show that there is a significant variation in stiffness among the individual joints of the robot and that the stiffnesses of the …
Updated insights into the mechanism of action and clinical profile of the immunoadjuvant QS-21: A review
2019
Background Vaccine adjuvants are compounds that significantly enhance/prolong the immune response to a co-administered antigen. The limitations of the use of aluminium salts that are unable to elicite cell responses against intracellular pathogens such as those causing malaria, tuberculosis, or AIDS, have driven the development of new alternative adjuvants such as QS-21, a triterpene saponin purified from Quillaja saponaria. Purpose The aim of this review is to attempt to clarify the mechanism of action of QS-21 through either receptors or signaling pathways in vitro and in vivo with special emphasis on the co-administration with other immunostimulants in new adjuvant formulations, called a…
