In this paper, a novel image descriptor, called Color Binary Correlation (CBC), is proposed for image retrieval. This method defines and describes the structure elements utilizing binary patterns based on colors and edge orientation respectively, and thus integrate texture with the other two properties. Besides, its variants CBCri and CBCu2, which are presented for rotated invariance and “unform”...
A hybrid energy storage system (HESS) plays an important role in balancing the cost with the performance in terms of stabilizing the fluctuant power of wind farms and photovoltaic (PV) stations. To further bring down the cost and actually implement the dispatchability of wind/PV plants, there is a need to penetrate into the major factors that contribute to the cost of the any HESS. This paper first...
We have established the Markov model for long range correlated time series (LRCS), by analyzing their evolutionary characteristics, then defined a physical effective correlation length (ECL) of the LRCS, which reflects the predictability of the LRCS, and find that the ECL has a better power law relation with the long range correlated exponent (LRCE) of the LRCS. We apply the power law relation between...
The article examines daily market index data of China stock markets from 1998 to 2008, and analyses fluctuation link trend between two regions' stock markets. Through Johansen co-integration test and Granger causality test, the paper finds the link between Shanghai and Shenzhen stock markets and Hong Kong stock market has become more closely linked and integration trend is remarkable. The strong relevancy...
The statistical data show that weather (precipitation) in the five dynamic climate characteristic regions simultaneously becomes dry, wet and normal, that is to say, each region possesses a common spatial-temporal characteristic structure. Further analysis of physical mechanisms suggests that the Jianghuai pattern and South China pattern are close related with ENSO, which may results from the effect...
