The fuzzy cluster analytical method is introduced here. By using this method the environmental monitoring sections of surface water of the three Liao River branches in Fuxin territory - the Liu River, the Raoyang River and the Yangximu River, were analyzed. Among the nine monitoring sections, the most polluted is at the downstream area of the Yangximu River, all of the pollution indexes, such as ammonia...
Directing at the complex structure, cockamamie production technology and great operation difficulty of vertical roller mill, this paper constructs the fault expert system to guide and optimize the grinding process. First, the expert database is established with fuzzy cluster analysis, principal component analysis (PCA) and tendency analysis. With support vector machine (SVM) regression, the multiple...
Fuzzy cluster analysis principle and calculation approaches are introduced. This method is applied to evaluate the change trend of water environment of urban water supply source. The fuzzy cluster analysis results are that water environment quality of water supply source was better in 1997, 1998 and 1999, but wore in 1996 and 2000. From this fuzzy clustering results, it can be known that the change...
