On the effects of centrifugal forces in air-water two-phase flow regime transitions of an adiabatic helical geometry

Creator:: Young, Eric P.
Abstract:: Two-phase flow in helical conduits is important in many industries where reaction between components, heat transfer, and mass transport are utilized as processes. The helical design is chosen for the effects of secondary flow patterns that reduce axial dispersion, increased heat transfer, and also their compact design. The first is...

A study of opposing mixed convection in the GRTS and in downward pipe flows using the FLUENT CFD code

Creator:: Jackson, R. Brian
Abstract:: Downward flow opposing mixed convection conditions have been studied using the FLUENT CFD code. This work was comprised of two primary objectives. The first was to study core channel flow reversal susceptibility in the Gas Reactor Test Section (GRTS) at low flow conditions. The second objective was the development of...

Integration of oceanographic information off the Washington and Oregon coasts into west coast groundfish ecology and fisheries management

Creator:: Juan Jorda, Maria Jose
Abstract:: To date, the use of oceanographic data in fisheries management has been limited by the scarcity and the difficulty of accessing complete oceanographic datasets. Consequently, fish stocks are managed with limited knowledge about the habitat where fish live and incomplete understanding of what oceanographic conditions affect their populations. With the...

Enhanced-accuracy oversampled data converters

Creator:: Ceballos, Jose Luis
Abstract:: Digital-to-analog converters (DACs) suffer from static and dynamic nonlinearity problems, which degrade their accuracy and performance. Mismatch errors in the analog components restrict the maximum achievable linearity. This thesis presents various techniques for correcting these errors. It describes a correction process for the nonlinear behavior of DACs, on three different...

A unified model of one-dimension two-fluid horizontal flows and its stability analysis

Creator:: Kim, Dong-Wan
Abstract:: An improved version of the one-dimensional horizontal two-fluid flow model has been developed by incorporating physical terms for gravity and local void fraction profiles. Introduction of an interface mixing layer concept allows the one-dimensional two-fluid model to remain hyperbolic. This will overcomes a major obstacle in using the current one-dimensional...

Estranged Eating

Creator:: Lacy, Amber D.
Abstract:: The “fat-hunger paradox” is a relatively recent phenomenon in the United States in which people of low socioeconomic status are disproportionately overweight or obese, and yet frequently lack access to adequate food and nutrition. Research indicates additional disparities in the prevalence of overweight and obesity amongst most racial and ethnic...

Plant community recovery after high severity wildfire and post-fire management in the Klamath Region

Creator:: Lopez Ortiz, Maria Jose
Abstract:: Disturbance and microclimate interact to play a central role influencing the composition and structure of plant communities. In this thesis, I examined plant community composition and structure twenty years after high severity wildfires with and without post-fire management (salvage logging, fuel treatment, tree planting, and shrub release) under contrasting microclimatic...

Impacts of demographic and economic change in Oregon's coastal communities : Case studies of Newport, Reedsport, and Gold Beach

Creator:: Zamora Arroyo, Jose Francisco
Abstract:: Coastal communities in Oregon have experienced dramatic economic and demographic change during the 1980s. Although the timber and fishing sectors are still important, the economies of coastal communities now rely more on non-earned income and tourism. Non-earned income sources, such as transfer payments and investment earnings, account for over forty...

Test of English as a foreign language (TOEFL) : good indicator for student success at Community Colleges?

Creator:: Ng, Jacob N. K.
Abstract:: Community colleges in the United States have become an important educational destination for international students. According to the Institute of International Education (IIE, 2006), international students who enrolled for the first time at a U.S. campus increased by 8 per cent, from 131,946 students in 2004/2005 to 142,923 in 2005/2006....

Evolution of volcanism and hydrothermal activity in the Yanacocha Mining District, northern Perú

Creator:: Longo, Anthony A.
Abstract:: The Yanacocha Mining District in northern Perú is considered the largest group of high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...
