Verticillium wilt, nematodes, and soil fertility interactions in hop yards

Creator:: Barth, Alexander W.
Abstract:: Verticillium wilt of 'Willamette' hops (Humulus lupulus) was investigated to identifY the causal organism, to determine the incidence of the disease, and to explore the possibility of interactions with soil fertility and/or nematodes. In the first year of a three year study, sampling of yards followed a "searching for extremes...

Interactions of wind-driven and tidally-driven circulation in the Oregon coastal ocean

Creator:: Osborne, John J.
Abstract:: Influences of tidal and slower (subtidal) oceanic flows over the continental shelf and slope off Oregon are studied using a high-resolution ocean circulation model and comparative model-data analyses. The model is based on the Regional Ocean Modeling System (ROMS), a fully nonlinear, three-dimensional model (using hydrostatic and Boussinesq approximations). The...

Ensemble-variational data assimilation for dynamically challenging coastal ocean circulation

Creator:: Pasmans, Ivo
Abstract:: Currently, forecasts produced by the Oregon-Washington (OR-WA) Coastal Ocean Forecast System are constrained by assimilation of only surface observations. The 4-dimensional variational (4DVAR) data assimilation (DA) algorithm is utilized to combine the model and the data, with the time-independent forecast ("background'') error covariance B. In this study, two possible improvements...

The Alexander polynomial

Creator:: Scherich, Nancy
Abstract:: The Alexander polynomial is a well understood classical knot invariant with interesting symmetry properties and recent applications in knot Floer homology. There are many different ways to compute the Alexander polynomial, some involving algebraic techniques and others more geometric or combinatorial approaches. This is an interesting example of how different...

Tidal-band and high-frequency internal variability on the central Oregon inner shelf

Creator:: Suanda, Sutara H.
Abstract:: Analogous to ocean surface waves, waves in the ocean interior also experience steepening, breaking, and dissipation as they approach the coastline. Much less is known about this internal beach. In this work, extensive moored Acoustic Doppler Current Profiler and temperature/salinity data together with optical remote sensing are combined to describe...

Verifying safe use of a thinner aluminum scattering chamber for fission physics

Creator:: Porter, Eben, Jr.
Abstract:: This thesis describes calculations done to determine the radiation hazard of the current Prompt Gamma Neutron Activation Analysis (PGNAA) scattering chamber at the Oregon State TRIGA Reactor (OSTR) and compare it to the amount that would be given off by a new thin-walled chamber design. These calculations were completed with...

Frequency-domain, parameter estimation for a brushless, doubly-fed machine

Creator:: Ramchandran, Ashok
Abstract:: A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages of conventional induction and synchronous types of electrical machines by its unique architecture. The validation of BDFM designs in an actual test environment requires the estimation of the BDFM model parameters from actual experimentation. Accurate values for the parameters...
