  • Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

    Creator:
    Baker, Joshua L.
    Abstract:
    This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

  • Unsaturated Soils and Foundation Design : Theoretical Considerations for an Effective Stress Framework

    Creator:
    Baker, Josiah D.
    Abstract:
    This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...

  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • Local scour at isolated obstacles on river beds

    Creator:
    Huang, Cheng-Chang
    Abstract:
    Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....

  • Laboratory investigation of the mechanics of raveling soils

    Creator:
    Saunders, George P.
    Abstract:
    Oregon's forestry industry has and will continue to be a vital component of Oregon's economy, with twenty-two percent of Oregon's 1986 gross state product and thirty-nine percent of Oregon's 1986 gross manufacturing product related the forestry goods. An integral component to proper management of Oregon's forestry lands is Sustaining the...

  • Stability of heterogeneous and anisotropic slopes determined by the compound logarithmic spiral limit equilibrium method

    Creator:
    Stockton, Ezra J.
    Abstract:
    The logarithmic-spiral (log-spiral) limit equilibrium procedure for slope stability analysis rigorously satisfies both force and moment equilibrium with a failure surface geometry formulated as a function of the soil’s angle of internal friction. Within the framework of limit equilibrium, this procedure has, in the past, been primarily limited to homogeneous...

  • Mathematical model of a phytoplankton community in a nitrate limited environment

    Creator:
    Grenney, William J.
    Abstract:
    Mathematical modeling of phytoplankton populations based on laboratory observations provides increased understanding of the interaction among the environmental and biological mechanisms. influencing growth dynamics. Such fundamental understanding is necessary to estimate the impact of man-made perturbations on natural population. A three-compartment mathematical model was developed to represent a phytoplankton population...

  • An Investigation of Student Cognitive Engagement in the STEM Classroom—A Compilation of Faculty and Student Perspectives

    Creator:
    Barlow, Allyson J.
    Abstract:
    Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...

  • Development of Authentic Engineering Curriculum through Collaborative Development: Research on Development and Adoption

    Creator:
    Cross, Matthew J.
    Abstract:
    Background: Studies indicate that problems utilized in traditional undergraduate engineering education do not adequately prepare students for the workforce. Calls to implement authentic, ill-structured problems into upper level engineering experiences may address this issue but adopting authentic engineering problems without considering barriers to adoption of faculty has not been fully...

  • Modeling estuary pollution by computer simulation

    Creator:
    Grenney, William J.
    Abstract:
    A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...
