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...

Overstory Growth, Structural Development, and Regeneration Success Following Uneven-Aged Conversion Treatments in Douglas-fir Plantation of the Cascade Range in Oregon

Creator:: Marcum, Sean R.
Abstract:: Uneven-aged management has been suggested as a method for balancing biodiversity conservation and wood production goals from managed forests in a variety of regions. In coastal Douglas-fir (Pseudotsuga menziesii) forests of the Pacific Northwest, implementation of uneven-aged management is hindered by a lack of experience with uneven-aged silvicultural systems, including...

Automated Tradeoff Analysis of Cost Versus Machinability for Design Feedback

Creator:: Grier, Alan Thomas
Abstract:: As CAD tools become more sophisticated, engineers are able to more easily create complex part geometries with minimal mass given strength and stiffness requirements. However, these complex part geometries can be difficult to subtractively manufacture, which consequently increases manufacturing cost and production time. This thesis presents a method independent of...

Design and Modeling Techniques for Impedance Based Flow Cytometry

Creator:: Dawes, Jacob
Abstract:: Microfluidic devices have enabled lab-on-a-chip (LOC) systems that allow for complex sample analysis and preparation in a compact form factor. One technology that may benefit from a microfluidic approach and further miniaturization is flow cytometry. Flow cytometry is an analysis technique for enumerating and characterizing populations of cells; this is...

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...

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....

The effects of supercritical CO₂ on the bending properties and treatment defects of four refractory wood species

Creator:: Anderson, Matthew E.
Abstract:: It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...

Comparison of two commercial detector arrays for RapidArc quality assurance

Creator:: Asay, Matthew Jamin
Abstract:: Radiation therapy is used in approximately half of all cancer treatments. The rapid advances in radiation therapy have led to techniques that are much more complex and therefore must be more carefully assessed for safety and efficacy. Accurate quality assurance methods must be implemented to provide patient safety and confidence...

An experimental reintroduction of Pleuropogon oregonus, a rare wetland grass native to Oregon

Creator:: Groberg, Matthew G.
Abstract:: Pleuropogon oregonus Chase is a rare wetland grass endemic to eastern Oregon. The species is composed of two widely separated populations, one in Lake County and one in Union County. In order to reduce the risk of extinction, the Oregon Department of Agriculture Native Plant Conservation Program initiated several reintroduction...

The use of wax spray beads (WSB) for iodine enrichment of Artemia sp. for use as a live food for zebrafish (Danio rerio) larvae

Creator:: Hawkyard, Donald Matthew
Abstract:: Dietary iodine may play an important role in the nutritional health of freshwater fish larvae. Artemia, commonly used for the culture of larval zebrafish (Danio rerio), contain low concentrations of iodine when compared with wild zooplankton. Water-soluble micronutrients, such as iodine, are difficult to deliver to Artemia due to rapid...
