introduction in ct imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. in order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. materials and methods the presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...
Clustering techniques are used to extract the structure of software for understanding, maintaining, and refactoring. In the literature, most of the proposed approaches for software clustering are divided into hierarchical algorithms and search-based techniques. In the former, clustering is a process of merging (splitting) similar (non-similar) clusters. These techniques suffered from the drawba...
Playing a central role in the information-systems research community’s discourse on design science has been the concept of the “IT artifact.” We pose the alternative concept of the “IS artifact.” We “unpack” what has been called the “IT artifact” into a separate “information artifact” and “technology artifact” that, together with a “social artifact,” interact to form the “IS artifact.” We illus...
