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 give thesis/dissertation in DRUM

    “Quite Young Limbs that Bled”: Accidents, Apathy, and the Failure of American Aviation During the First World War
    (2024) Getka, Dana; Giovacchini, Saverio; History; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    The advent of the First World War saw America’s first concerted attempt at building a world-class air service. Desperate to join the ranks of Britain, Germany, and France, it pushed poorly-built planes out of factories and poorly-trained cadets out of flying schools at an alarming rate. In this thesis, I argue that in blind pursuit of its goals, the United States air service ultimately doomed those whose efforts would bring the organization its prestige: the pilots. Aviators, especially non-combatants in roles such as training, testing, and ferrying, faced unavoidable death or harm every time they stepped into a plane, be it physically, emotionally, or psychologically. Despite their role as non-combatants, these pilots well understood that destruction would characterize their world, provoking emotional responses expected of those engaged in fighting on active fronts. Indeed, flying was a world of combat unto itself, and by war’s end, the Army Air Service had earned the dubious distinction of being the only arm of the United States military in which more men were violently killed in non-combat than in combat roles.

    Determining the Number of Slots to Submit to a Market Mechanism at a Single Airport
    (2007-05-09) Churchill, Andrew Michael; Lovell, David J; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In this thesis, several stochastic optimization models are presented to determine the number of airport arrival slots that should be made available for distribution via a market mechanism. Considerable attention is paid to the structure and mathematical properties of each of these models, with regards to obtaining integer-valued solutions. Calibration of the various parameters is undertaken using historical data. In addition, an analysis of the average pecuniary valuations assigned to each slot is presented, as this is an essential input to these models. Several methods are suggested by which each of these values can be estimated. The models are intended to be taken in a general context, but extensive computational examples making use of data for LaGuardia Airport are provided as a case study in the application of the various techniques presented herein.
