This research investigates a k-out-of-n system in which the lifetime of operational and standby components, the repair time follow continuous phase-type (PH) distribution, instead of exponential distribution or others typical distributions. The proposed paper provides an analytic reliability model that is more suitable to characterize the real situation. The stationary distribution is built by using...
It is necessary to conduct current decoupling control, because there is non-linear coupling in PMSM servo system with position, speed and current closed-loops. Based on voltage space vector control and current vector control program, it is enable to make the linear decoupling come true in PMSM servo system. Though analyzing the math model of the servo system, facing to id = 0 strategy of vector control,...
In heterogeneous multi-core systems, such as the Cell BE processor, each accelerator core has its own fast local memory without hardware supported coherence and the software is responsible to dynamically transfer data between the fast local and slow global memory. The data can be transferred through either a software controlled cache or a direct buffer. The software controlled cache maintains correctness...
Based on the qualitative analysis and research of implementing Reduce Vertical Separation Minimum (RVSM) to enhance the flight capacity in RVSM airspace all over the world, using systemic approaches that combine the qualitative analysis with ration analysis, this paper introduced mathematic description and neural network model of the air traffic issue in RVSM airspace. The mathematic description is...
