In this paper, we focus on embodiment aspects of communication between human and single function artifact. Communication with embodiment media between human and artifact is difficult because of the difference of embodiment. We discuss a bottom up process and top down process of designing a common understand of embodiment media between human and artifact. keywords: human-artifact communication, ...

Iodine is commonly used as a contrast agent in nonmedical science and engineering, for example, to visualize Darcy flow in porous geological media using X-ray computed tomography (CT). Undesirable beam hardening artifacts occur when a polychromatic X-ray source is used, which makes the quantitative analysis of CT images difficult. To optimize the chemistry of a contrast agent in terms of the be...

The digital X-ray detectors often generate stripe artifact in the sinogram which in turn creates ring artifact in the reconstructed micro-Computed Tomography (μ-CT), C-Arm CT, and most recent dental CT images. Such ring artifacts not only obscure image details in the regions of interest but also mask the whole image with some artifacts. In this paper, novel techniques are proposed for the detec...

Electrocardiographic artifact is generally considered to be a nuisance. Respiratory artifact, however, is a physiologic signal that may carry useful diagnostic information. Our goal was to evaluate the characteristics, prevalence, and clinical significance of respiratory artifact observed in electrocardiograms (ECGs). ECGs exhibiting repetitive microoscillations were systematically collected. T...
