The fuzzy model proposed by Takagi and Sugeno can represent highly nonlinear systems and is widely used for the representation of fuzzy rules. In this paper, the model is firstly modified to make its identification easier. Based on the fuzzy c-partition space, four criteria are proposed for optimization of the model parameters. Following that, a clustering(More)
Three-year-old 'Zaozhong No. 6' loquat (Eriobotrya japonica Lindl.) seedlings were foliar-sprayed with 0.2, 0.5, 1.0 and 1.5 mmol x L(-1) of sodium nitroprusside (SNP), subjected to low temperature (-3 degrees) stress for 6 hours, and then cultured at 25 degrees C for four days. The antioxidant metabolites and enzymes in the seedling leaves were determined(More)
The monthly sampling data from June 2012 to May 2013 were used to study the composition and structure of the crustacean zooplankton community in the lakes and rivers of Suzhou Industrial Park. The variations in density and biomass of the crustacean zooplankton and their relationship with the environment factors were investigated. The results showed that a(More)
