Ardisia violacea (Myrsinaceae), one of China’s rare and endangered species, occurs only in Zhejiang and Taiwan provinces. We examined the population dynamics of this species to reveal details related to the development of populations. Assembling intensity indices were used, such as V/m, K, m * , PAI, CA and I. Age class structure and the time-specific life tables were analyzed by the contiguous...
Over-actuated manipulator has capability of fault tolerance. If faulted actuators do not exceed system redundancy number, the manipulator may retain working normally by redistributing driving force with proper fault tolerant policy. Based on the D'Alembert principle and the equivalent force method, a plane 2-DOF over-actuated parallel manipulator dynamics model was established. Furthermore, a dynamics...
