On the demand price elasticity and revenue, the traditional economics analysis result is that when E > 1, price and revenue reverse change; E <; 1, price and revenue are changing direction, Unit demand price elasticity, revenue is not with price changes ;But this conclusion is conditional. Through the proof: Unit price elasticity, any changes will reduce returns; When E <; 1, if prices don't...
Illustrated with Qiantang estuary , Hangzhou Bay, the relationship between structure of coastal geomorphology and dissipation of tidal energy were analyzed and the landscape ecological mechanism of watershed flood was studied based on the theory of the landscape ecology and quantitative assessment method of landscape characteristic index. By Correlation analysis and multiple linear regression analysis...
Concept lattice is a form of conceptual classification of the object or concept hierarchy based on the crisp relation between object set and attribute set. It has been used with a high intensity to knowledge reduction. Through the in-depth study of concept lattice, this paper presents the definition and natures of attribute importance in concept lattice, and accordingly illuminates an attribute reduction...
Because of the space complexity of the multi-layer underground transportation hub terrorist activities, the space limitation results in the single escape route, difficulty for vertical rescue, long distance and short time to relief and other features. For these problems, counter-terrorism emergency response system is build; develop contingency plans are developed; the counter-terrorism mechanisms...
This paper introduced a data embedding technology different from traditions. The study is based on visual C++ programming with interface. For convenience of users, It got over traditional defect of embedding technology. This study also produces new ideas in the aspect of precise correction. A more precise TIN-based method is assumed. Using this method, the errors of the corrected image is about one...

To find effective estimations of tail dependence, we present the estimators of upper tail dependence coefficient by using survival copula. We research to two problems by using the samples from t-copula. Firstly, do the estimators estimate effectively the upper tail dependence coefficients of copula? Which is the best among the estimators? Secondly, if sample isn't from true distribution, do the estimators...
