A hybrid mechanism is a configuration that combines the motions of two characteristically different electric motors by means of a mechanism to produce programmable output. In this paper, by means of establishing mathematic model for the influence of output accuracy of a planar hybrid five-bar mechanism affected by manufacturing error of link length, the sensitive coefficient of manufacturing error...
Proposed the services composition algorithm based on QoS which combined local strategy and global strategy for constraints. The algorithm eliminates the services with low QoS firstly and then reduces the problem of services composition plan selection for global QoS guarantee to multi-dimension multi-choice 0-1 knapsack problem which is solved by the heuristic method for improving the efficiency of...
Particle impact noise detection (PIND) is a reliable screening technique specified by MIL-STD-883E. But MIL-STD-883E gives some test conditions which are not always appropriate. The test conditions of PIND are derived here based on dynamics. The upper limit frequency expression is obtained by a transforming equation. How vibration acceleration, vibration frequency, recovery coefficient, particle mass,...
In this paper, dynamic modeling is investigated for shear stress induced adenosine triphosphate (ATP) release from endothelial cells (ECs). The modulation of ATP concentration at the endothelial surface by viscous shear flow is extensively investigated through numerical analysis based on the release model. The simulation results demonstrate that shear stress induced ATP release, convection and diffusion...
