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...

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...

background: the electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful. objective: removing electrocardiogram contamination from electromyogram signals. methods: in this paper, the clean electromyogram signal, electrocardiogram artifact and...
