  • Linear theory of roll instabilities in the ocean surface layer

    Creator:
    Duncombe, Jenessa R.
    Abstract:
    This thesis describes the results of a linear stability analysis conducted on a simulated wind-forced ocean front. The ocean surface boundary layer regulates exchanges between the ocean and atmosphere, and the presence of turbulence in the surface layer can greatly impact climate and ocean life. Past research has shown that...

  • Field validation of a nearshore circulation model for alongshore-nonuniform flows

    Creator:
    Wilson, Gregory W.
    Abstract:
    We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...

  • A modeling study of katabatic flows

    Creator:
    Smith, Craig M.
    Abstract:
    A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, a sensitivity study of katabatic flows to various physical parameters, and an investigation into the...

  • Evaluation of factors contributing to the failure of cast iron water mains

    Creator:
    Takahashi, Gilbert Tamaji
    Abstract:
    An evaluation was made of factors contributing to the service failure of a 12 inch diameter cast iron water pipe in Pendleton, Oregon. The quality of the pipe was found to be acceptable when compared to the acceptance limits established by the American National Standards Institute, Inc. However it exhibited...

  • Development test suite for FPGA TekBot learning platform

    Creator:
    Lai, Gerald
    Abstract:
    As the Tekbots program expands into senior and graduate level classes at Oregon State University, so does the need arise for more complex learning platforms. These complex hardware platforms cannot be adequately tested in a manufacturing environment as we have done previously. Also, due to their complexity, these platforms require...

  • A comprehensive integration of first year engineering education

    Creator:
    Shuman, Matthew W.
    Abstract:
    Retention of engineering students is a problem for many universities, especially during the first year. The problem of introducing students to engineering while increasing retention rates has recently been addressed by many different universities. Implementing novel lab structures, adjusting the lecture to incorporate more effective teaching techniques, and using orientation...

  • A household production approach to modeling household recycling effort

    Creator:
    Martini, Roger
    Abstract:
    Household recycling is an important means by which social costs of solid waste disposal may be reduced. These costs include energy and resource costs of collection and disposal as well as environmental costs from emissions from landfills, incinerators, and collection vehicles. In this thesis, a household production model is used...

  • Potential impacts of climate change on vegetation distributions, carbon stocks, and fire regimes in the U.S. Pacific Northwest

    Creator:
    Rogers, Brendan M.
    Abstract:
    The U.S Pacific Northwest contains a wide variety of ecosystems, all subject to relatively dry summers and wet winters. As has been shown with paleoclimatic and paleoecological data, the region is vulnerable to changes in climate. We assessed the sensitivities of vegetation distributions, carbon stocks, and fire regimes to 21st...

  • Guarantees and requirements : implementation and complexity analysis of a new model of types for declarative visual programming languages

    Creator:
    Chen, Roger Ding-Fu
    Abstract:
    Djang et al. [1998] introduced a new model of types for declarative visual programming languages (VPLs). Implicit static typing is used in their type model, in order to eliminate the programming mechanisms associated with type declarations, provide immediate visual feedback with respect to type errors and guarantee type safe programs....
