  • Ultra sonic SCUBA diver tracking device hardware

    Creator:
    Lindsley, Christopher J.
    Abstract:
    Currently, there is no accurate, low-cost method to track divers. Watching bubbles can give you an approximate xy-location, and expensive underwater radios utilizing ultrasonic waves can work if the diver knows where they are. Traditional radio waves do not work well in water due to the conductive nature of water....

  • Gray codes and their applications

    Creator:
    Anantha, Madhusudhanan
    Abstract:
    An n-bit Gray code is an ordered set of all 2n binary strings of length n. The special property of this listing is that Hamming distance between consecutive vectors is exactly 1. If the last and first codeword also have a Hamming distance 1 then the code is said to...

  • Low-complexity high-speed VLSI design of low-density parity-check decoders

    Creator:
    Cui, Zhiqiang
    Abstract:
    Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...

  • Microwave extraction of peppermint oil and comparison to the currentpractice of steam extraction

    Creator:
    Velasco, Carmen A.
    Abstract:
    The increase of diesel fuels and natural gas has increased the energy cost of the mint oil extraction industry in the Willamette Valley. In this study the energy evaluation of a distillation facility in Oregon is considered. Solvent free microwave extraction of peppermint oil is introduced as a new technique...

  • Phenotypic evolution as a response to thermal ecology in the ferocious waterbug Abedus herberti (Hemiptera: Belostomatidae)

    Creator:
    Pelegrin, Arthur Lomis
    Abstract:
    Over 150 years ago, C. Bergmann observed a within-species pattern of increasing body size as elevation and latitude increased. Bergmann’s data came from numerous endothermic taxa, but the pattern has since been documented among numerous poikilotherms and invertebrates. The ferocious waterbug Abedus herberti Hidalgo (Hemiptera: Belostomatidae) lives in isolated populations...

  • Efficacy of lateral heel wedge orthotics for the treatment of patients with knee osteoarthritis

    Creator:
    Wallace, David A.
    Abstract:
    Lateral heel wedge orthotics are designed to reduce medial tibiofemoral joint loading and pain in patients with knee osteoarthritis (OA). To date, the efficacy of long-term lateral heel wedge orthotics use among OA patients has not been determined. This study evaluated the extent to which lateral heel wedge orthotics reduced...

  • The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

    Creator:
    Boyle, Stephanie A.
    Abstract:
    The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...

  • Culture built upon the land : a predictive model of nineteenth-century Canadien/Métis farmsteads.

    Creator:
    Hebert, James Michael
    Abstract:
    The objective of this thesis is to provide a predictive model for the archaeological investigation of the first farmsteads in the Pacific Northwest, established in the early- and mid-nineteenth century by Canadien and Métis families retiring from their service in the fur trade. Past studies of this population have either...

  • Architectural crusades : a comparison and interpretation of French cathedrals and American mega churches as cultural catalysts and material culture

    Creator:
    McKenzie, Karen and McKenzie, Karen E.
    Abstract:
    The Gothic cathedrals of France arose in a particular social and political environment, and the material culture, the structures themselves and their contents, bear witness to those realities even today. In addition, the cathedrals themselves were catalysts for cultural change. They encouraged urban growth in a country that had previously...

  • Deep ultraviolet solid-state laser development

    Creator:
    Dutton, David A. (David Adam)
    Abstract:
    There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...
