  • The Mathematical Knowledge for Teaching of First Year Mathematics Graduate Teaching Assistants : The Case of Exponential Functions

    Creator:
    Keeling, Matthew
    Abstract:
    A teacher's mathematical knowledge for teaching has been shown to have a positive correlation with their students' success (Monk, 1994). So, when half of the students that start out in a STEM major switch out to a non-STEM major before graduation to in large part to instructors pedagogical methods and...

  • Modeling and development of p-type thin-film transistors

    Creator:
    Spiegelberg, Matthew Craig
    Abstract:
    The primary focus of this thesis involves modeling and development of p-type thin-film transistors (p-TFTs), moving towards the realization of a filly transparent thin-film transistor (TTFT). The modeling portion of this thesis emphasizes the development of physics-based TFT models, specifically focusing on the elucidation of non-ideal current-voltage characteristic behavior. A...

  • Silvicultural Treatment Impacts on Understory Trees and 20-Year Understory Vegetation Dynamics in Mature Douglas-Fir Forests

    Creator:
    Priebe, Jim E.
    Abstract:
    Policy regarding the management of public forests has undergone a drastic shift over the past couple of decades due to the loss old-growth forests in the Pacific Northwest (PNW) of the United States. For much of the 20th century, forest management on public lands emphasized timber production through the use...

  • Effectual Entrepreneurship and its Application to a Microfluidics R&D Startup

    Creator:
    Brown, Matthew E.
    Abstract:
    An inventor seeks to leverage his unique means in order to create and commercially exploit new technologies. Until new technologies are sufficiently developed, they have the theoretical potential for commercial exploitation in a wide range of markets. Those opportunities are limited by physical bounds that are often only discovered through...

  • 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...

  • Effects of Pediococcus spp. on Oregon Pinot noir

    Creator:
    Strickland, Matthew T.
    Abstract:
    This research investigated the effects of Pediococcus spp. on Oregon Pinot noir wines. Pediococcus (P. parvulus (7), P. damnosus (1), P. inopinatus (1)) isolated from Oregon and Washington state wines demonstrated differences in their susceptibility to SO₂ with some isolates growing well in model media at 0.4 mg/L molecular SO₂....

  • Automated Synthesis of Planar Mechanisms with Revolute, Prismatic and Pin-In-Slot Joints

    Creator:
    Huang, Weifeng
    Abstract:
    The intent of this research is to explore the entire design space of mechanism topologies by using a graph grammar synthesis approach. A new graph representation of planer mechanism has been developed to represent the planar mechanism with revolute (R), prismatic (P), and pin-in-slot (RP) joints. Following Gruebler's equation, the...

  • Cytochrome P-450 monooxygenases in the mosquito, Culex pipiens

    Creator:
    Baldridge, Gerald D.
    Abstract:
    A sucrose density-gradient ultracentrifugation technique for obtaining microsomes has been developed. This technique has advantages over the classic differential centrifugation technique, in that it is faster, is better suited to work with small quantities of tissue, and offers the opportunity to work with a defined microsomal sub-cellular fraction, rather than...

  • Factors Influencing Conversion and Volume Stability in Calcium Aluminate Cement Systems

    Creator:
    Adams, Matthew P. (Matthew Peter)
    Abstract:
    There is renewed interest in North America for the use of calcium aluminate cement (CAC) in infrastructure repair. The interest is driven by the specialty properties that make CAC the ideal candidate for particular applications. These include rapid strength gain, even at temperatures approaching 0°C, the ability to customize fresh...

  • A spatially explicit network-based model for estimating stream temperature distribution

    Creator:
    Cox, Matthew M.
    Abstract:
    The WET-Temp (Watershed Evaluation Tool Temperature) model is designed to take advantage of spatially explicit datasets to predict stream temperature distribution. Datasets describing vegetation cover, stream network locations, elevation and stream discharge are utilized by WET-Temp to quantify geometric relationships between the sun, stream channel and riparian areas. These relationships...
