Based on the principle that every terms of Taylor series are odd or even,the segment calculation method in the course in power system transient analysis can be derived in simpler way, which helps to provide a new teaching method and a better understanding on the part of the students.

The general expressions are obtained by using the conclusion from teaching material with the charged square coil considered as four sections charged rods,using partition computation and the principle of superposition of field.

A piecewise algorithm for retrieval of suspended sediment concentration based on in situ spectral data by MERIS in Zhujiang River estuary

In this paper,we discussed piecewise algorithm of a kind of standard Graphs and its application in the shortest path problem in detail,piecewise algorithm and its application has been achieved in computer,a comprehensive algorithm time complexity is O(e),better than traditional methods.
