    This details the progress of the ENERCON pump replacement project as completed by the Kennesaw State University interdisciplinary senior design group. This project is a two-semester capstone effort for the engineering program at Southern Polytechnic School of Engineering, overseen by Dr. McFall during Fall 2020 and Dr. Khalid during Spring 2021 semesters. The 2020-2021 KSU Interdisciplinary Senior Design team was tasked with completing an Engineering Change Package (ECP) for existing vacuum pumps at ENERCON Station. The mechanical, electrical, and civil students worked together, performing evaluations on existing plant systems to ensure the plant could support the new vacuum pumps. By tying into the plants existing Plant Service Water (PSW) System and electrical grid, and by reusing existing pipe supports as well as designing new ones, it has been determined that the existing ENERCON Station Systems will support the new Nash Liquid Ring Vacuum Seal Pumps and their supporting equipment. All evaluations have been submitted to ENERCON along with all necessary plant documents that have been revised to show the new equipment

    Improved Nearside-Farside Decomposition of Elastic Scattering Amplitudes

    A simple technique is described, that provides improved nearside-farside (NF) decompositions of elastic scattering amplitudes. The technique, involving the resummation of a Legendre partial wave series, reduces the importance of unphysical contributions to NF subamplitudes, which can arise in more conventional NF decompositions. Applications are made to a strong absorption model and to a 16^{16}O + 12^{12}C optical potential at Elab=132E_{\text{lab}} = 132 MeV.Comment: 5 pages, 2 figure

    Beyond the senses: perception, the environment, and vision impairment

    Get PDF
    The ‘sensory turn’ in anthropology has generated a significant literature on sensory perception and experience. Whilst much of this literature is critical of the compartmentalization of particular ‘senses’, there has been limited exploration of how anthropologists might examine sensory perception beyond ‘the senses’. Based on ethnographic fieldwork with people who have impaired vision walking the South Downs landscape in England, this article develops such an approach. It suggests that the experiences of seeing in blindness challenge the conceptualization of ‘vision’ (and ‘non‐vision’). In place of ‘vision’ (as a sense), the article explores ‘activities of seeing’ – an approach that contextualizes the visual to examine the biographically constituted and idiosyncratic nature of perception within an environment. Through an ethnography of seeing with anatomical eyes and ‘seeing in the mind's eye’, it articulates an approach that avoids associating perception with anatomy, or compartmentalizing experience into ‘senses’
