In order to investigate the relationship between standardized death rate for area and 50% mortality rate for burn area (LA(50)), correlation analysis, curve estimation and linear regression were performed with the variables. The results showed that: (1) there was a similarity in sort order of standardized death rate in control groups of samples, compared(More)
For rice blast gray system with complex nonlinearity, utilizing of gray ant colony model and RBF neural network model characteristics, gray ant colony and RBF neural network combination model is presented in this paper. After 10 years (2002-2011) prediction analysis of rice blast, the prediction accuracy of this project is up to 97.84%, and verifies the(More)
