In this paper, we study on evaluating physical education teaching quality based on the entropy model. The entropy model is a measure of the uncertainty associated with a random variable, which is a powerful tool in many research fields. Next, a physical education teaching quality evaluation method is designed by obtaining the maximum information entropy based on the index systems, which include 12 categories index, such as include continuous variables effect factors and discrete variables effect factors. To demonstrate the effectiveness of the proposed method in physical education teaching quality evaluation, an experiment is conducted on ten datasets to make performance evaluation comparing with the results obtained by the students evaluation and experts evaluation. © 2013 IEEE.

The constrained Delaunay triangulation algorithm is not very stable or even failure when the influence domain is concave polygon. In this paper, we introduce some related conceptions and algorithms and focus on the Constrained Delaunay Triangulation Algorithm and Influence domain that is concave polygon issues related. An improved algorithm based on the diagonal exchange is presented. Experiments show that the algorithm can solve the influence domain for concave polygon and other special circumstances, and can be implemented by programs easily, and be stable. ©2010 IEEE. Source
