Extended abstract 1- Introduction Evaluation is a process of assessing the degree of achievement to determined goals. In the meantime, choosing the right method for evaluating the effects will have a significant role on the results and management strategies. Therefore, considering the importance of check dams in watershed management programs in Iran, in this study, performance of check dams i...
Abstract Spacing between check dams depends on the stream bed slope, effective height of check dams and slope of deposited sediments behind the check dams. The slope of deposited sediments is more important than the other two factors because of complications in the way of its occurrence and its measurement after several years of dam construction. This research presents the effective factors a...
A class of maximum-girth geometrically structured quasi-cyclic (QC) low-density parity-check (LDPC) codes with columnweight J 3 is presented. The method is based on the slope concept between two circulant permutation matrices and the concept of slope matrices. A LDPC code presented by a mv ×ml parity-check matrix H , consisting of m ×m matrices each of which is either a circulant permutation ma...
