in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

A module is called uniseriat if it has a unique composition series of finite length. A ring (always with 1) is called serial if its right and left free modules are direct sums of uniserial modules. Nakayama, who called these rings generalized uniserial rings, proved [21, Theorem 171 that every finitely generated module over a serial ring is a direct sum of uniserial modules. In section one we g...

W hen law enforcement apprehends a serial murderer, the event is consistently the focus of unswerving media coverage. For local communities, the ordeal can be particularly shocking and upsetting. Residents living in a community that is exposed to serial murder may even experience posttraumatic stress disorder symptoms for varying periods of time (Herkov and Beirnat, 1997). Over the past three d...
