Excitation control is one of the effective means to improve the stability of Power System. Excitation controller, which uses the Nonlinear characteristics and learning ability of Neural network, also the characteristics of adaptive control technology, has strong adaptability and robustness for the nonlinearity and uncertainty of the system. The simulation results to the single machine infinite bus...
The banknote recognition system based on hidden Markov models (HMM) is proposed. It is based on the empirical risk minimization (ERM) principle. Image preprocessing includes brightness equalization and tilt correction. In order to satisfy the high speed and reliability of the banknote processing system, the grid segmentation is used for features extraction. Analyze the experimental data and determine...
With the development of international dry & bulk cargo market, international dry & bulk cargo seaborne trade is increasing rapidly, many kinds of dry & bulk cargo terminals were built along our countrypsilas coast, there even appears the problems of repeated constructions and fierce competition among these ports leading to an lower utilization efficiency with our coastline resources. Under...
