A combined influence assessment model is established based on grey cluster method in this paper to analyze the combined influence of plantation logging on the environment-resource-cost system. The modeling results show that in the process of skidding and hauling, the higher the degree of mechanization, the less the compositive consumption. Moreover, the compositive consumption of small equipment is...
This paper presents a study of the analysis of breast density in missed cancer cases and the effect of tissue density on caner detection. A total of 100 missed cancer cases were collected. The breast density tissue was segmented with a statistical-based method. A set of tests was then applied to examine: (1) the differences in density between the mammograms at the detected stage and that at missed...
This study is part of the research of improving early detection of breast cancer in screening mammograms by focusing on computerized analysis and detection of cancers missed by radiologists. It is directed to the analysis of breast density in missed cancer cases and the effect of tissue density on cancer detection. A total of 100 missed cancer cases were collected which were used to generate three...
