Analysis of evapotranspiration for various climatic regimes using geostatistics

Creator:: Nuss, Jeffery L.
Abstract:: Research was conducted to determine the applicability of using the theory of regionalized variables or geostatistics in characterizing the spatial variability of reference evapotranspiration (ETr) over various climatic regimes for the state of Oregon. The state was divided into five climatic regions based on topographic features and local meteorological conditions:...

Aerobic Cometabolism of 1,4-Dioxane and cis-Dichloroethylene by Gellan Gum and Polyvinyl Alcohol/Sodium Alginate Hydrogel Beads Co-Encapsulated with Rhodococcus rhodochrous Strain ATCC 21198 and Slow-Release Growth Substrates: Batch, Column, and Toxicity Studies

Creator:: Conway, Sean P.
Abstract:: 1,4-Dioxane (dioxane) and cis-dichloroethylene (cDCE) are compounds commonly found in industrial cleaning and degreasing agents that are frequently present as groundwater contaminants. In an effort to develop a more effective treatment method for these compounds, hydrogel beads were fabricated with either gellan gum or a combination of polyvinyl alcohol (PVA)...

Evaluation in a Physical Aquifer Model the Long-Term Performance of a Permeable Reactive Bio-Barrier Packed with Co-encapsulated Gellan Gum Beads for the Bioremediation of Chlorinated Compounds and Co-Contaminants

Creator:: Wortkoetter, Jacob
Abstract:: Chlorinated solvents are a class of widespread groundwater contaminants that are toxic, carcinogenic, and difficult to remediate at low concentrations. 1,4-dioxane, a suspected carcinogen, is often a co-contaminant found in mixtures of chlorinated solvent plumes. In-situ bioremediation methods of degrading these chemicals through aerobic cometabolism have shown promise. Permeable Reactive...

Examination of Photochemical Water Treatment by SolarBags

Creator:: White, Robert E.
Abstract:: Inadequate access to clean water is an ongoing problem in many developing areas of the world. In developed nations, it is important to plan for access to clean water following natural disasters. In situations without reliable access to electricity and chemical treatment methods, there is a need for an inexpensive...

Modeling of Non-Spherical Particle Dynamics in a Non-Uniform Flow

Creator:: Alshehri, Ahmad S.
Abstract:: Turbulent flow with suspended, non-spherical particles can be found in nature and several industrial applications. Although turbulence with dispersed spherical particles has been studied extensively, modeling the dynamics of non-spherical particles in a turbulent flow has not been studied extensively. Motion of spherical particles in complex flows is typically captured...

Practical Application of the Finite Element Method for Vehicle System Loads Analysis

Creator:: Weitzman, Paul M.
Abstract:: This work develops the loads, boundary conditions, and model construction techniques used to create a high-level vehicle analysis model. The loads are derived from the overall performance parameters of the vehicle, which include 3 axis accelerations and aerodynamic forces from Computational Fluid Dynamics outputs. The boundary condition of the analysis...

Wave-by-wave Forecasting of Sea Surface Elevation for WEC Applications Utilizing NARX Neural Networks

Creator:: Gillespie, Alice
Abstract:: Forecasting of ocean waves over a short duration on the order of tens of seconds was approached with the optimization of wave energy conversion in mind. This study outlines the development of an artificial neural network model, specifically the Nonlinear Autoregressive Network with Exogenous Input (NARX), to predict a wave-by-wave...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Experimental study of impulse turbines and permanent magnet alternators for pico-hydropower generation

Creator:: Cobb, Bryan R.
Abstract:: Increasing access to modern forms of energy in developing countries is a crucial component to eliminating extreme poverty around the world. Pico-hydro schemes (less than 5-kW range) can provide environmentally sustainable electricity and mechanical power to rural communities, generally more cost-effectively than diesel/gasoline generators, wind turbines, or solar photovoltaic systems....
