Astigmatism’s defect has not yet been formulated in Physics and medical physics books theoretically. In this paper, we are trying to formulate the astigmatism’s defect. The results of formulation show that “the degree of astigmatism is negative reverse the distance that vision’s condition of astigmatism’s chart lines change conditions in dimness angle from dimness condition at infinite distance...

On the basis of analyzing the classical algorithms of network clustering and community detecting, a new algorithmic method of discovery of community was brought up, which has different thinking from previous algorithms. In this method a general network is looked upon as a corresponding electrical network firstly, the link in between the connected pairs of nodes is substituted by a fixed resisto...
