Tropical cyclones are the most common natural disasters in coastal regions and are the most costly in terms of economic losses. Economic loss assessment is the basis for disaster prevention and alleviation and for insurance indemnification. We use data from 1970 to 2008 for Zhejiang Province, China, in this study evaluating economic losses. We convert direct economic losses from tropical cyclone disasters...
This study demonstrates the potentials of HJ-1 hyperspectral sensor (110-128 bands)-based estimation of aboveground biomass in Hangzhou Bay Zhejiang Province, China. We coupled AGB values, calculated from field measurements of vegetation, with six different vegetation indices derived from HJ1 data through regression analyses to produce an initial biomass map. The results showed that above-ground biomass...
The fractal Characters of copper future price returns in Shanghai Futures Exchange are numerically investigated by the Rescaled Range Analysis (R/S Analysis), a fractal method widely used to detect the persistence and long-range memory in time series. We estimate the values of Hurst exponents H to examine the persistence of the copper future price time series at different time-scales ??= 1, 2, 5,...
Echinococcosis, both cystic and alveolar, and Taenia solium cysticercosis are the most serious zoonotic cestodoses worldwide. Because of the emerging importance of these diseases in China, several international workshops and meetings were held in this country from 1998 to 2001. Based on round table discussions in Chengdu 2000, the proposal of a strategy to control echinococcosis and cysticercosis...
