  • 3-D seismic imaging of an active margin hydrate system, Oregon continental margin : report of cruise TTN 112 R/V Thomas Thompson, June 19 - July 3, 2000

    Creator:
    Tréhu, Anne Martine and Bangs, Nathan Lawrence Bailey
    Abstract:
    In the past several years, international interest in gas hydrates in marine sediments has increased considerably because of increasing recognition that the large volume of gas stored in hydrates or trapped beneath them is a significant fraction of the global methane budget, and may therefore be a source of energy...

  • Desegregation, integration and the charter of Portland Public Schools

    Creator:
    Doyle, Judith Helene
    Abstract:
    Portland Public School District and in particular Jefferson High School are examined in a functionalist framework to determine the extent to which they meet community needs. B. Malinowski's functionalist theory is employed to analyze desegregation and integration policies and actions of the Portland Public School District and Jefferson High School,...

  • Foam enhancing properties of hop bitter acids and propylene glycol alginate

    Creator:
    Kunimune, Takeshi
    Abstract:
    The following two projects have been carried out to clarify the impact of these foam stabilizers, and to compare their foam stabilizing power to one another as well as the cling ability. The first project investigated the impacts of four commercially available hop- derived foam stabilizers; iso-alpha-acid (Iso), rho(dyhydro)-iso-alpha-acid (Rho),...

  • Fiber Bragg grating-tunable diode laser

    Creator:
    Ericksen, Doug
    Abstract:
    Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

  • 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...

  • Energetics and mechanics of swing phase during terrestrial locomotion

    Creator:
    Nelson, Frank E.
    Abstract:
    Previous attempts to understand the factors affecting the energetic cost of locomotion have found a direct link between the energetic cost and the mechanical work done during periods when the limb is in contact with the ground. However, when the limb is not in contact with the ground during the...

  • The influence of an elevated incubation temperature on the expression of clubbed down in Coturnix embryos

    Creator:
    Charbonneau, Jack R.
    Abstract:
    Hatchability of the fertilized avian egg is impacted by factors which can be categorized as being either genetic or environmental in nature. An elevated incubation temperature, > 100 F reduces development time (time, days to hatch), but increases embryonic mortality and lowers the numbers of fertile eggs that will hatch....

  • Model-based approximation methods for reinforcement learning

    Creator:
    Wang, Xin
    Abstract:
    The thesis focuses on model-based approximation methods for reinforcement learning with large scale applications such as combinatorial optimization problems. First, the thesis proposes two new model-based methods to stablize the value–function approximation for reinforcement learning. The first one is the BFBP algorithm, a batch-like reinforcement learning process which iterates between...

  • Genetic dissection of Victoria blight disease susceptibility in Arabidopsis thaliana

    Creator:
    Sweat, Teresa A.
    Abstract:
    The fungus Cochliobolus victoriae causes Victoria blight of oats and Arabidopsis and is pathogenic due to its production of a compound called victorin, which induces programmed cell death in sensitive plants. Victorin sensitivity in Arabidopsis is conferred by the dominant gene LOCUS ORCHESTRATING VICTORIN EFFECTS1 (LOV1), which encodes a coiled-coil-nucleotide...

  • A probabilistic model for anomaly detection in remote sensor streams

    Creator:
    Dereszynski, Ethan W.
    Abstract:
    Remote sensors are becoming the standard for observing and recording ecological data in the field. Such sensors can record data at fine temporal resolutions, and they can operate under extreme conditions prohibitive to human access. Unfortunately, sensor data streams exhibit many kinds of errors ranging from corrupt communications to partial...
