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.

Item WATERFRONT REGENERATION: Mediating Boundaries of Abandonment Along the Hudson River(2015) Palmadesso, Allison Rose; Lamprakos, Michele; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The edge between city + water has become a divide. This thesis addresses this edge that has been thickened by abandoned industry and challenges the way we design for our changing waterfronts through a design approach relying on specificity of place. The design proposal shows how the water/city divide can become a connective threshold, how industrial landscapes can be reclaimed, and how this place-specific investigation can be an example to learn from through Westchester County’s Hudson River Waterfront, the City of Yonkers, and the abandoned Glenwood Power Plant. This method has resulted with the integration of building into landscape so that it acts as part of a new infrastructure which cleans water, supports urban agriculture, and provides recreational and training opportunities for the surrounding community. Flows have been re-purposed to knit connections in all axes, and begin to heal water’s edge.Item Air Pollution Response to Changing Weather and Power Plant Emissions in the Eastern United States(2008-11-20) Bloomer, Bryan Jaye; Dickerson, Russell R; Atmospheric and Oceanic Sciences; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Air pollution in the eastern United States causes human sickness and death as well as damage to crops and materials. NOX emission reduction is observed to improve air quality. Effectively reducing pollution in the future requires understanding the connections between smog, precursor emissions, weather, and climate change. Numerical models predict global warming will exacerbate smog over the next 50 years. My analysis of 21 years of CASTNET observations quantifies a climate change penalty. I calculate, for data collected prior to 2002, a climate penalty factor of ~3.3 ppb O3/°C across the power plant dominated receptor regions in the rural, eastern U.S. Recent reductions in NOX emissions decreased the climate penalty factor to ~2.2 ppb O3/°C. Prior to 1995, power plant emissions of CO2, SO2, and NOX were estimated with fuel sampling and analysis methods. Currently, emissions are measured with continuous monitoring equipment (CEMS) installed directly in stacks. My comparison of the two methods show CO2 and SO2 emissions are ~5% lower when inferred from fuel sampling; greater differences are found for NOX emissions. CEMS are the method of choice for emission inventories and commodity trading and should be the standard against which other methods are evaluated for global greenhouse gas trading policies. I used CEMS data and applied chemistry transport modeling to evaluate improvements in air quality observed by aircraft during the North American electrical blackout of 2003. An air quality model produced substantial reductions in O3, but not as much as observed. The study highlights weaknesses in the model as commonly used for evaluating a single day event and suggests areas for further investigation. A new analysis and visualization method quantifies local-daily to hemispheric-seasonal scale relationships between weather and air pollution, confirming improved air quality despite increasing temperatures across the eastern U.S. Climate penalty factors indicate amplified smog formation in areas of the world with rising temperatures and increasing emissions. Tools developed in this dissertation provide data for model evaluation and methods for establishing air quality standards with an adequate margin of safety for cleaning the air and protecting the public's health in a world with changing climate.Item Memory of the Future: Adaptive Reuse of the Seaholm Power Plant, Austin, Texas(2006-05-18) Davis, Matthew Earl; Wortham, Brooke D; Architecture; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This thesis will investigate ways in which elements and cues can be introduced to an existing building to serve the memory of the future. The project will serve as a continuation of time and space, linking what the building has been to present and future evolutions. This thesis will investigate several types of built interventions to the historic and currently unused Seaholm Power Plant site in downtown Austin, Texas, creating something greater than but inherently associated with the physical structure itself. Utilizing a concept of structures existing in different states of permanence, with different influences on memory, this project will test the ability to design into a collective memory. The attempt will be made to embellish the life and story of the Seaholm building, linking the ways it has been know before, is remembered and used now, and how it will project our heritage to those that await us.
