The calculation of importance measures is based on the individual basic event in probabilistic safety assessment (PSA). In some cases, the decision maker usually concerns about the equipment or component importance measures, which can not be calculated directly in PSA. In this paper, several methods to calculate component importance measures are discussed first. a new importance measure called "Equipment...
In wireless self-organized network (WSON), AOW clustering algorithms can achieve better performance and high adaptability, but having limitations in certain circumstances. In this paper, working procedure and shortcomings of AOW are introduced and analyzed firstly. Then, several modified algorithms based on AOW are designed according to system requirements. Simulation experiments are conducted to...
LMRE is a key tool for railway maintenance, whose function is lifting and moving the rail for repairing. The LMRETB is designed for testing the LMRE lifting high, lifting pressure and sinkage after 3 minutes keeping pressure. The pressure loading system of the test bench is an electric-hydraulic pressure servo control system. Because the overshoot and slow response of the pressure hydraulic control...
