Simulation is widely used to predict the performance of complex systems. The main drawback of simulation is that it is slow in execution and the related compute experiments can be very expensive. On the other hand, analytical methods are used to rapidly provide performance estimates, but they are often approximate because of their restrictive assumptions.(More)
With the development of modern signal processing and computer network technology, it brings new challenges to remote health care structure. This paper discusses a prototype which realizes the functions of physiological signal collection and calculation, GPS global positioning, and data transmission through GPRS. The new type of portable multi-life-parameter(More)
