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.

    Optimization of Carbon Monoxide Detectors in a Residential Layout and Analysis of Dispersion Characteristics
    (2012) Engel, Derek; Trouvé, Arnaud; Fire Protection Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Current building and life safety standards do not specify the optimal placement of carbon monoxide (CO) detectors in residential structures. Currently, the standards advise to follow manufacturer's instructions, place one centrally on each floor and in each HVAC zone. With the use of computation fluid dynamics (CFD) software FLACS, simulations were run to observe and track CO concentrations, generated from a fire source, throughout a demonstrative box as well as a residential structure under different source and ambient conditions. A MATLAB script was developed to represent CO detector functionality. From this it was possible to evaluate detector placement throughout a structure. The time to detection criterion was analyzed as well as order of alarm in relation to other placements. Final recommendations are presented based upon the dispersion patterns observed.
