One problem for tour planner applications is to support dynamic tour paths based on tourists changing states. This paper introduces a concept of tour node space and ways of supporting dynamic tour paths by manipulating the tour-node-transition threshold. A prototype implemented using Google Maps JavaScript API demonstrates how an optimized multiple waypoint tour path and up-to-date direction information...
As a new kind of cylindrical gear, the in volute arch cylindrical gear has preferable transmission characteristics, but its main geometry parameters have no unified standard. In this paper, the ideal geometry parameters of in volute arch cylindrical gear are proposed and its tooth surface equation and meshing line equation are discussed. For verification, the computer graphics is introduced to show...
