Studies on several well-known blackouts reveal that the weakest parts of network, where branch MW flow limit violations most possibly occur, are the transmission lines suffering from flow transferring most greatly after the overloaded line tripping. Therefore, this paper attempts to speed up the solution by means of partial solutions instead of the whole network solution.

Neural networks based on local sequence and amino acid component with the best structures and linear equation are constructed. The results of testing to the networks indicate that the forming of cis-proline has distinct relationships with local sequence and amino acid component. A new method for peptidyl prolyl cis/trans conformation prediction based on the theory of support vector machines was introduced. The SVM represents a new approach to supervised pattern classification and has been successfully applied to a wide range of pattern recognition problems.
