This paper deals with the design, fabrication and experimental validation of several modules of a micro-assembly system. On one hand, a microgripper is integrated in a four degrees of freedom system. On the other hand, a tool changer is designed. It enables to exchange automatically the tip part of the microgripper and then dedicated tools can be used to achieve specific tasks. The principle of...
the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...
This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in ...
Automation of the mounting of cryocooled samples is now a feature of the majority of beamlines dedicated to macromolecular crystallography (MX). Robotic sample changers have been developed over many years, with the latest designs increasing capacity, reliability and speed. Here, the development of a new sample changer deployed at the ESRF beamline MASSIF-1 (ID30A-1), based on an industrial six-...
pain management is crucially important in the postoperative period as it increases patient comfort and satisfaction. the primary outcome of present study was to evaluate the effect of sufentanil added to hyperbaric bupivacaine solution 0.25% in transversus abdominis plane (tap) block, on postoperative analgesic consumption. fifty asa physical status i–ii term primiparous single-tone pregnant wo...
We present circuits and techniques which allow the extraction of fine-grained timing information using a simple, scan-based, test-access port such as the JTAG/IEEE 1149 standard. We go on to show how these techniques can be combined with other simple circuits for post-fabrication timing control. These techniques open up opportunities to perform timing oriented tests through TAP control. Further...
