The Eco-hydrology of Tropical Peatlands Associated with Land Cover Changes

Creator:: Kurnianto, Sofyan
Abstract:: Tropical peatlands play an important role in global climate system by storing an immense of carbon that had been accumulated over thousands of years. Peatlands provide another important ecosystem service by regulating the hydrology. It is believed that peatlands act like a giant sponge by absorbing substantial amounts of water...

Lasers in the Sky : Distributed Temperature Sensing and a Micro-Meteorological Approach to Quantifying Evapotranspiration

Creator:: Predosa, Robert
Abstract:: Lower atmospheric flux measurements are a difficult subset of atmospheric data to accurately collect. The interplay of cost, precision, specialty, resolution and repeatability compound an already difficult experimental problem. In response to this, a new, novel instrumentation approach to measuring within the atmospheric boundary layer (ABL) is introduced. The combination...

Composite Tools and Optimization in Racecars to Reduce Mass and Design Time

Creator:: Wagoner, Marshall
Abstract:: Designing a carbon fiber chassis for the Global Formula Race car has historically proven to be both time intensive and difficult. The goal of this thesis is to improve the design process for testing Global Formula Racing team's composite chassis sandwich panels. Consideration was taken regarding Formula SAE rules, and...

Non-Isotropic Fiber Reinforced Elastic Membranes for Micro Aerial Vehicle Wings

Creator:: Wilcox, Joshua Robert
Abstract:: Micro air vehicles (MAV's) and small unmanned aerial vehicles (SUAV) are remotely piloted or autonomous aircraft with a take-off mass range between 50 g and few kilograms. These vehicles, as well as natural fliers such as bats and insects, utilize a variety of elastic wing structures including thin membranes. Over...

Effects of Initial Moisture and Surface Properties on Sorptivity of Coarse Soil and Sand

Creator:: Ambrowiak, Gloria M.
Abstract:: Many different models and mechanisms of water imbibition into soil have been described in the literature. Theoretical equations based on those models exist to predict how water will flow in porous media. These models can be useful, but have their weaknesses. Research on imbibition and infiltration into soils has mostly...

An investigation into the pore-scale mechanisms of capillary trapping : application to geologic CO₂ sequestration

Creator:: Herring, Anna L.
Abstract:: Geologic CO₂ sequestration is a climate change mitigation strategy that prevents CO₂ emissions to the atmosphere by capturing CO₂ gasses from large point source emissions streams and then pressurizing and pumping the supercritical-state CO₂ into underground geologic storage reservoirs. Once underground, CO₂ is prevented from buoyant migration to the surface...

Design and manufacturing study of hydroelectric turbines using recycled and natural fiber composites

Creator:: Whitehead, Marc
Abstract:: The objective of this project is to demonstrate the feasibility fiber-reinforced turbine components through a design and manufacturing study. The motivation for using composites is to reduce weight and simplify manufacturing especially at high production volumes. In addition, natural fiber composites are implemented for applicable components to reduce environmental impact....
Resource Type:: Masters Thesis

Experimental design of physical aquifer models for evaluation of groundwater remediation strategies

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...

Learning approaches for the early detection of kickback in chainsaws

Creator:: Arnold, Drew D.
Abstract:: Among the many safety hazards facing chainsaw operators, the phenomenon known as kickback is the most dangerous. Kickback occurs when the chain at the tip of the chainsaw is caused to stop abruptly, and transfers the energy of the cutting chain to motion of the saw. The saw will rotate...
Resource Type:: Masters Thesis

Implementing best management practices in small commercial and non-commercial animal enterprises

Creator:: Godwin, Derek C.
Abstract:: Small commercial and non-commercial animal enterprises (SCAEs) raise a few beef cows, horses, pigs, sheep, poultry, and other animals on a few acres. These enterprises are often located in suburban areas of watersheds and show potential for degrading water quality through to increased bacterial, nitrogen, and phosphorus concentrations. SCAEs implement...
