New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a given thesis/dissertation in DRUM.

More information is available at Theses and Dissertations at University of Maryland Libraries.

    ANALYSIS OF SCYE BEARING MOTION AS APPLICABLE TO THE DESIGN OF A MORPHING SPACESUIT
    (2011) Bradshaw, Heather; Akin, David L; Aerospace Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This thesis describes research supporting the development of the Morphing Upper Torso spacesuit design, which uses robotic augmentation of a rear-entry pressure suit to adjust torso dimensions. This concept has the potential to provide increased mobility, easier ingress/egress of the suit, and reduced astronaut workload during extravehicular operations. A range of motion study has been conducted in which subjects wore simulated shoulder scye bearings while performing selected tasks, with the intent to measure human motion in relation to scye bearing motion. Results of the study include an investigation of the neutral pose of the scye bearings in Earth gravity, an analysis of the angular range of motion observed for the right scye bearing, and the development of a heuristic model to predict scye bearing position and orientation as a function of known arm pose.
