  • 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...

  • Effects of Thinning on Tradeoffs Between Drought Resistance, Drought Resilience, and Wood Production in mature Douglas-fir in Western Oregon

    Creator:
    Elfstrom, L. Madelene
    Abstract:
    Recent climate projections predict more frequent and severe drought conditions in western Oregon which is a threat to forest health, productivity, and structure. Land managers are increasingly concerned with how to create forest drought resistance: a tree or stand’s ability to maintain its growth rates during a drought, and resilience:...

  • 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...

  • Reburn Severity and Vegetation Recovery in Southwestern Oregon, USA

    Creator:
    Weber, Rebecca N.
    Abstract:
    The Klamath-Siskiyou Ecoregion of southwest Oregon and northern California is greatly departed from its historic, mixed-severity fire regime. This departure manifests in larger wildfires, greater proportions of high burn severity within wildfire perimeters, and decreased diversity of post-fire vegetation successional stages and trajectories across the landscape compared to historical norms....

  • Estimating Tree Defect and Log Quality with Terrestrial Structure from Motion Photogrammetry and Handheld LiDAR

    Creator:
    Morgan, Carli J.
    Abstract:
    Forest inventories are periodic resource assessments that can estimate items such as timber volume and value, tree growth rates, carbon sequestration, forest health status, wildlife habitat, fuel loading, and more. Traditional inventories require a large investment of resources and well-trained workforce. To date, most foresters and timber cruisers inventory forests...

  • 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....

  • 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...

  • 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...

  • 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...
