  • Feasibility of utilizing an integrating nephelometer to measure visibility

    Creator:
    Nelson, William George
    Abstract:
    An integrating nephelometer was set up at the Eugene Airport which is located five miles north of Eugene, Oregon, on Highway 99 West. Continuous atmospheric scattering coefficient readings were obtained from July 1, 1969, to August 28, 1969. These data are converted to meteorological range through the use of the...

  • Partial recirculation of diesel engine exhaust for the reduction of oxides of nitrogen

    Creator:
    Addicott, Donald James
    Abstract:
    Oxides of nitrogen are a concern as effluents to atmospheres because they participate in photochemical reactions which produce smog, because they attenuate sunlight which gives the atmosphere a reddish brown cast, and because of their toxic properties and the health hazards associated with the photochemical products they produce. Oxides of...

  • A portable dual-range fuel flowmeter for automotive research

    Creator:
    Hodgkins, Chester
    Abstract:
    This describes the development of a new fuel flowmeter. Among the desired features were an accuracy of ±2%, a linear response to fuel flow rate, a means of increasing the sensitivity at the low end of the meter scale and portability so that it would be equally useful in the...

  • Exploring experimental test stand design and operation within a system reliability research methodology

    Creator:
    Koopmans, Michael, 1986-
    Abstract:
    In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

  • Chemometrics-based Approach for Predicting Low Temperature Combustion Engine Fuel Performance

    Creator:
    Daly, Shane
    Abstract:
    Low temperature combustion (LTC) engines offer improved efficiency and reduced emissions over traditional gasoline spark-ignited and diesel compression-ignition engines. The ability to produce fuels optimized for LTC engines could help increase efficiency and therefore improve fuel economy, insomuch that Federal fuel economy standards could be met. Currently, a fuel performance...

  • Quality driven collaborative decision making for product development under the influence of trustworthiness

    Creator:
    Meier, Stefan
    Abstract:
    The focus of this study is the effective prioritization of customer requirements in collaborative product development. The CR priorities are often retrieved by questioning and interviewing targeted customers. But the targeted customer might not always be easily questioned, because they might not always be obvious or clearly known. If customers...

  • Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

    Creator:
    Strahl, Jordan D.
    Abstract:
    The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

  • Fouling Characterization in Hypersaline Wastewater Treatment

    Creator:
    Messer, Morgan S.
    Abstract:
    Water supplies are diminishing worldwide and by 2025 two thirds of the population could be living in regions of water scarcity (local demand for water is greater than water supply). One method to increase available water sources is to use desalination technologies to separate water from saline solutions. While desalination...

  • Simulating changing diameter distributions in a softwood sawmill

    Creator:
    Salichon, Maxence C.
    Abstract:
    Sawmills are very complex systems that involve many manufacturing processes. The variability of their raw material adds further to this complexity as each log has characteristics that determine its processing path. Therefore, computer simulation is a very useful technique for analyzing sawmill performance. This thesis describes a simulation computer model...
