Electroencephalogram (EEG) is susceptible to various nonneural physiological artifacts. Automatic artifact removal from EEG data remains a key challenge for extracting relevant information from brain activities. To adapt to variable subjects and EEG acquisition environments, this paper presents an automatic online artifact removal method based on a priori artifact information. The combination o...

Background Simultaneous assessment of myocardial scar or perfusion reduction and coronary artery stenosis is currently performed by side-by-side comparison or image fusion using coronary CTA and myocardial perfusion study, but the misregistration and differences in spatial resolution between imaging methods can be problematic. A CMR technique that can visualize both myocardial scar and coronary...

Background Characterization of carotid artery morphology and plaque composition requires multiple measurements with different contrast-weightings, which are limited by long scan time, image misregistration, and expertise-dependency in image interpretation. Recently, a new method,3D Multicontrast ATherosclerosis CHaracterization (MATCH) has been developed to overcome the above drawbacks by acqui...

This paper documents emotion as integral to stakeholders’ sense making of a key organizational artifact, demonstrating that emotion toward artifacts blends into emotion toward the organization. Multiple stakeholders were interviewed about an artifact of a large public transportation organization. Sense making of the artifact is shown to involve emotion in interpretations that consider three dim...

The evaluation of two DSW300 film scanners was performed using good quality test patterns and accurate processing methods. The geometric tests include global and local geometric errors, misregistration between colour channels, geometric repeatability and determination of the geometric resolution. The radiometric tests include investigations of noise, linearity, dynamic range, spectral variation...
