Design of compact folded-line RF power dividers

Creator:: Lim, Chi-young
Abstract:: Embedded passives in multi-layer media have gained importance for offering an attractive solution to the implementation of off-chip passive components in RF and mixed signal circuits, especially for wireless applications. Among the passive devices, power dividers and combiners are extensively used for a host of applications including balanced mixers, phase...

Model development via delay extraction for the time-domain simulation of lossy transmission lines.

Creator:: Blevins, Chris
Abstract:: This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....

Effect of varying levels of vitamin B-6 intake on lymphocyte mitogenic response and vitamin B-6 concentration in human peripheral blood mononuclear cells

Creator:: Kwak, Ho-Kyung
Abstract:: Two studies were conducted to determine the effect of varying vitamin B-6 (B- 6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP) concentration in peripheral blood mononuclear cells (PBMC) in young women. In the first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...

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...

Genomic Resource Development and Studies of Thermal Tolerance in Symbiotic Cnidarians

Creator:: Elder, Holland L.
Abstract:: Reef building corals are the foundation of an entire ecosystem, but they are threatened primarily by rising ocean temperatures due to climate change. Corals depend on a thermally sensitive symbiosis with intracellular dinoflagellates. As oceans warm, this symbiosis is disrupted and results in coral mortality, declining populations and degraded reefs....

Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

General design rules for the allocation of buffers in closed serial production lines

Creator:: Staley, Dan R.
Abstract:: One of the classic problems in industrial engineering is the buffer allocation problem. The objective of the buffer allocation problem is to maximize some line output, typically throughput, through the allocation of buffers throughout the production line. Previous work in this area has focused on either determining general design rules...

Using Change Representations to Analyze Properties of Variational Software

Creator:: Wang, Xiangyu
Abstract:: Appropriate representations of variational software simplify the analysis of their properties.This thesis proposes tailored representations of two kinds variational softwares: difference files of merge commits in Git and feature models. For the former, we use the Choice Edit Model, which is based on the choice calculus, to represent changes introduced...

Viscosity of the Zr₄₁.₂Ti₁₃.₈Cu₁₂.₅Ni₁₀.₀Be₂₂.₅ bulk metallic glass forming alloy above the liquidus temperature

Creator:: Way, Christopher D.
Abstract:: The viscosity of Zr[subscript 41.2]Ti[subscript 13.8]Cu[subscript 12.5]Ni[subscript 10.0]Be[subscript 22.5] (Vit1) has been measured above the liquidus temperature, T[subscript liq]=1026 K, using a high vacuum high temperature rapid annealing furnace equipped with a Couette Concentric Cylinder Rheometer. Steady state measurements have been taken over a temperature range of 1075-1300 K and...

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...
