  • Women's commuter cycling apparel : functional design process to product

    Creator:
    Steinhardt, Lauren
    Abstract:
    Bicycle commuting is increasing in popularity due to exercise benefits, cost savings, and environmental concerns. Available specialized cycling apparel does not reflect the aesthetic and expressive needs of the bicycle commuter. Urban bicycle commuters need clothing that allows them to bicycle safely and effectively while maintaining their identity as professionals....

  • Wheeled Mobility Devices Performance and Passive Securement Systems

    Creator:
    Mather, Andrea
    Abstract:
    Wheeled mobility devices (WhMD) pose unique safety risks to users while riding public transportation. Unsecured or improperly secured WhMDs create safety concerns for other transit riders and operators. Tests using accelerometers and visual observations were conducted to understand how WhMD orientation and securement in articulated buses, streetcars, and light rail...

  • Vertical Axis Pendulum Wave Energy Converters : Investigating Control Strategies and the Deployment of a Scaled Generic Prototype

    Creator:
    Boren, Blake C.
    Abstract:
    Vertical Axis Pendulum Wave Energy Converters (VAPWECs) are thought to be both effective and robust at converting ocean wave energy into usable electricity. Seeking to build upon and investigate such potential, this work examines the merits of actively controlling a generic VAPWEC's pendulum for the purpose of increasing the converter's...

  • Towards reliable and survivable ocean wave energy converters

    Creator:
    Brown, Adam C.
    Abstract:
    Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

  • Thinning with prescribed fire and timber harvesting mechanization for fuels reduction and forest restoration

    Creator:
    Matzka, Peter J.
    Abstract:
    In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

  • The quantitative evaluation of radiological workplace indicators

    Creator:
    Brock, Terry A.
    Abstract:
    Two research studies at the U.S. Department of Energy's Hanford Site and Rocky Flats Environmental Technology Site (RFETS) explore the quantitative relationship between surface contamination, airborne radioactivity, worker intakes, and subsequent dose. In the first study, resuspension factors are developed and evaluated at the U.S. Department of Energy's (U.S. DOE)...

  • The geometric characterization and thermal performance of a microchannel heat exchanger for diesel engine waste heat recovery

    Creator:
    Yih, James S.
    Abstract:
    Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...

  • The design and development of the wearable health and activity monitor

    Creator:
    Glover, Neil E.
    Abstract:
    This work describes the development of an accurate, low-cost, expandable and wearable health and activity monitoring platform. Wearable monitors used to track physical activity are becoming an increasingly popular and effective way to combat our dangerously sedentary lifestyles. Unfortunately most existing wearable solutions are either costly, inaccurate or cumbersome. The...

  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...

  • Radioxenon generation using highly enriched uranium

    Creator:
    Elliott, Anthony James
    Abstract:
    This work focuses on the generation and collection of four specific radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These nuclides are created by fissioning a highly enriched uranium sample using a thermal neutron source from a university research reactor. The three main aspects of this work include: (1) Conducting preliminary...
