Abstract. In order to improve the steady output of micrgripper, the giant magnetostrictive micrgripper with flexure hinge is taken as the research object . Its structure and working principle are presented .the static performance experiments are done and the better linear work domain is found. On the basis of that the dynamic model of the microgripper is established and the formula of the micro...

Recent research work concerning cooperative and concurrent engineering, increasingly interest industrial firms. Companies can no longer ignore this approach due to industrial needs such as improvement of quality and reduction of cost and delay. The objective of this paper is to propose an approach allowing the different experts or firms, to cooperate via Internet. To facilitate the communicatio...

Computer-Aided Inspection Planning (CAIP) has been a research topic for the past 25 years. Most of the CAIP systems were developed for Coordinate Measuring Machines (CMMs). The authors reviewed these CAIP systems and categorized them into two groups: tolerance-driven and geometry-based CAIP systems. Compared with CMMs, On-Machine Inspection (OMI) systems provide direct inspection in manufacturi...

. The objective of STEP is to provide a neutral data model capable of describing product data throughout the life cycle of a product that is independent from any particular software application or computer platform. AP203, AP214, AP224 promote the integration of CAD/CAM system. Now STEP-NC, a new extension of STEP, is being developed. A truly integrated CAD, CAPP, CAM and CNC paradigm is now in...

In this paper, we show a general way to interpret the infrastructure of a global field of arbitrary unit rank. This interpretation generalizes the prior concepts of the giant-step operation and f -representations, and makes it possible to relate the infrastructure to the (Arakelov) divisor class group of the global field. In the case of global function fields, we present results that establish ...

We discuss the nonabelian world-volume action which governs the dynamics of N coincident Dp-branes. In this theory, the branes’ transverse displacements are described by matrix-valued scalar fields, and so this is a natural physical framework for the appearance of noncommutative geometry. One example is the dielectric effect by which Dp-branes may be polarized into a noncommutative geometry by ...

We construct a new harmonic family: dielectric flow solutions with maximal supersymmetry in eleven-dimensional supergravity. These solutions are asymptotically AdS4 ×S7, while in the infra-red the M2 branes are dielectrically polarized into M5 branes. These solutions are holographically dual to vacua of the mass deformed theory on M2 branes. They also provide an interesting insight on the super...
