Segmentation and extraction of the target feature points from the unregistered, noisy data set of human body scanning and measuring are discussed. We have fitted the noise scanned data line with KS principal curve, which is based on the K-means theory. The crossing zero of curvature was used to segment and estimate the position of target feature points. And optimization scheme named variable fuzzy partition is also presented to improve the searching for local feature area.

In general under ideal perfect competitive environment, because of the replaceability the active output of a certain generating set will fall in vast scale while its bidding price is slightly raised, and the sensitivity index based on its own price will be a very small negative value; along with the increment of market power this index will gradually increase until sensitivity index becomes zero. This conclusion can be spread to the situation of multi-generating sets.
