Supercomputer Design: An Initial Effort To Capture The Environmental, Economic, And Societal Impacts, Marshall T. Mcdonnell

Faculty Publications and Other Works -- Chemical and Biomolecular Engineering

Abstract Currently, the Green500 is possibly the largest effort to direct the evolution of supercomputing towards sustainable design but does not address life-cycle impacts of a supercomputer. Supercomputer assessment with economical, environmental, and societal impacts considered would provide an optimal future supercomputer design that is sustainable. Some of the benefits of such an assessment would help determines the complete impact for bringing a supercomputer online, determine impact “hot spots” in design, and determine optimal locations for construction. By combining process-LCA and EIO-LCA methods, an initial model for in-depth sustainability analysis of supercomputer design has been developed and the results presented. …

Background: Blue-gray ovoids (B-GOs), a critical dermoscopic structure for basal cell carcinoma (BCC), offer an opportunity for automatic detection of BCC. Due to variation in size and color, B-GOs can be easily mistaken for similar structures in benign lesions. Analysis of these structures could afford accurate characterization and automatic recognition of B-GOs, furthering the goal of automatic BCC detection. This study utilizes a novel segmentation method to discriminate B-GOs from their benign mimics.

Methods: Contact dermoscopy images of 68 confirmed BCCs with B-GOs were obtained. Another set of 131 contact dermoscopic images of benign lesions possessing B-GO mimics provided a …
