A test fixture and deembedding procedure for high-frequency substrate characterization

Creator:: Webb, Kyle M.
Abstract:: At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...

Examining effectiveness of Oregon’s forest practice rules for maintaining warm-season maximum stream temperature patterns in the Oregon Coast Range

Creator:: Fleuret, Jennifer Marie
Abstract:: Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas (RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...

Community-based sea turtle monitoring and management at Helen Reef, Hatohobei State, Republic of Palau

Creator:: Barr, Julie M.
Abstract:: Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...

10Be exposure ages of erratic boulders in southern Norway and implications for the history of the Fennoscandian Ice Sheet

Creator:: Goehring, Brent M.
Abstract:: This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age and...

Initial state estimation for a gun launched projectile in a spatially varying magnetic field

Creator:: Chawla, Feni
Abstract:: Smart weapons promise to provide leap ahead capability with regard to accuracy and engagement range for medium and large caliber projectiles. One of the most critical components of a smart weapon system is its sensor suite that provides position, orientation, and velocity information as the projectile flies down range so...

Scaled modeling and simulation of ocean wave linear generator buoy systems

Creator:: Gore, Ganesh P.
Abstract:: Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

Automating aquatic insect identification through pattern recognition

Creator:: Thomas, Joshua K.
Abstract:: Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...

Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

Creator:: Mazurkiewicz, Adam B.
Abstract:: The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...

The phytosanitation of solid wood packaging materials using wood preservatives

Creator:: Schauwecker, Christoph F.
Abstract:: New species introductions have been associated with the movement of people for thousands of years. For instance, horses were introduced into North America by Spanish explorers, while pigs were introduced by the Polynesians into many Pacific islands long before the establishment of permanent European settlements. Both of these species introductions...
