Combined with Web Services technology, we design virtual enterprise dynamic alliance system. The system structure is mainly includes three roles: the customer, the core enterprise and member enterprises. Using openness of the Internet and the specification of the protocol, we provide a loosely coupled data layer and application layer integration among enterprises. Dynamic alliance system service uses...
In order to resolve the redundant information in High-tech project evaluation, a high-tech investment risk evaluation model combining a rough sets RS and the RBF neural network is presented. First using the rough set's powerful numerical analysis capabilities, this model does the attribute reduction on the evaluation index which reduces the training data of RBF neural network and simplifies the network...
In order to improve the level of automation for pulse signal processing and recognition, firstly, it used the fast Fourier transform with radix-2FFT algorithm to extract the characteristic parameters of pulse in frequency domain. Secondly, it made the dyadic discrete wavelet transform in four scales with MALLAT algorithm and calculated the detail energy values of four scales to constitute together...
The paper describes a manner in which the energy-reliability optimization of wind energy conversion system's operation can be achieved by means of the fuzzy sliding mode control. An appropriate sliding surface has been found in the speed-power plane, which allows the operation more or less close to the optimal regimes characteristic. What is more, by torque controlling the generator, an energy-reliability...
