This paper proposed a new hybrid forecasting model for the prediction of ozone concentrations in semi-arid area. It is based on chaotic, particle swarm optimization algorithm (CPSO) and back propagation (BP) neural network, called CPSO-BP neural network. The results show that the proposed hybrid model is superior to both the BP neural network and the regression model being tested. The hybrid model...
We utilize the mixed exponential power asymmetric GARCH model where each component exhibits asymmetric conditional heteroskedasticity to model Shanghai Stock Exchange Composite Index daily returns. Thanks to extra component-specific shape parameters, it can better capture the tail behavior and match the stylized facts of high frequency financial time series precisely and parsimoniously. The application...
This paper applies the TYDL procedure to test the comparative advantage of the banking system vs. stock market in China. For the availability of the data, we confine our analysis between 1992Q1 to 2008Q4. Empirical result shows that there exists bi-directional Granger causality between the banking development and the economic growth in China; on the contrary, evidence implies that the stock market...
Genetic algorithm is a efficient way to solve the logistics-related problem, the mathematic model is analyzed and the key technology of building simulation model in eM-Plant is researched in this paper, and also the build-in genetic algorithm of optimizing module is used to optimize picking system based on the eM-Plant simulation model, which can assure the scientific decision.
The current engineering quality management model and its problems in China are analyzed in this paper; an engineering quality risk innovative project management model based on risk-oriented is established on the risk management theory and engineering insurance theory. The ?? supervision afterwards?? management is turned to the ?? risk pre-control?? management based on the innovative project management...
KIII model is an olfactory neural networks bionic model proposed by Walter J. Freeman. Its architecture simulates that of olfactory neural system, which is different from other artificial neural networks. Through simplifying KIII model, a color texture generating algorithm is proposed combining with RGB. In RGB space, the tricolor of each pixel (red, green and blue) is used as the model input and...
