  • 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...

  • Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

    Creator:
    Ambauen, Spencer J.
    Abstract:
    A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...

  • Students' Conceptual Understanding of Mechanics and Materials for Axial and Bending Load Cases

    Creator:
    Berger, Amber D.
    Abstract:
    As people learn new concepts, they experience a process termed conceptual change. There are several theories that attempt to explain conceptual change, and this paper uses the framework theory to explain how students learn mechanics of materials. Semi-structured interviews with ninety students were qualitatively analyzed for this research in an...

  • Applications of Marine Radar Wave Observation Systems

    Creator:
    Meskill, Shay J.
    Abstract:
    This project utilized both shore-based and shipboard commercial marine radar technology to collect wave statistics. In the first application a shore-based system was installed at Yaquina Bay in Newport, Oregon in order to collect real-time wave information. This information was collected under the auspices of the Northwest Association of Networked...

  • Establishing a through-boring pattern and method of test for utility poles

    Creator:
    Elkins, Lori A.
    Abstract:
    The goal of this study was to optimize a through-boring pattern that will provide adequate preservative penetration while minimizing the reduction in overall pole bending strength. Hole spacing was developed using longitudinal and transverse chemical penetration data from previous studies. Finite element analysis was used as a preliminary assessment tool...

  • Bacterial toxicity and metabolism of three hydrazine fuels

    Creator:
    Kane, Donald A.
    Abstract:
    Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

  • Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

    Creator:
    Lathrop Eve D.
    Abstract:
    The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...
