In this paper, a new hybrid model of amino acid substitution is developed and compared with the others in previous works. The results show that the new hybrid model can characterize the protein sequences very well by calculating Fisher weights, which can denote how much the variants contribute to the classification.
This paper studies various classifiers to identify primary, secondary or tertiary alcohols by using segmental spectra and their combinations to support vector machines （SVMs）. The results showed that the O-H in-plane bending absorption contributed most to identification their substitute. This conclusion disagrees with related known research results.

The main idea and algorithm of the projection pursuit regression(PPR)based on immune evolutionary algorithm(IEA)are introduced to study the data of the Dongguan’s precipitation of 2003.The model of PPR was built to predict the pH value in precipitation.The result shows this method is steady and has good prediction precision,and has a better prediction result than that of MLR.
