Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

Creator:: Dennis, Michael L.
Abstract:: Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

Measurement of the rates of reductive dechlorination of chlorinated phenols

Creator:: Nicholson, David K.
Abstract:: Knowledge of a compound's degradation pathway is crucial to the assessment of risk at contaminated sites. Pentachlorophenol and its metabolic products can serve as model compounds to study the fate and transport of halogenated aromatic compounds in the environment. Acclimation of anaerobic sewage sludge to pentachlorophenol produced a microbial consortium...

An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

Creator:: Babbel, Benjamin J.
Abstract:: Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

Numerical Characterization and Modeling Uncertainty of Frame-Spine and Frame-Spine-FLC Full-Scale Specimens Tested at E-Defense Shake-Table

Creator:: Astudillo, Bryam
Abstract:: The characterization of the seismic performance of structures relies on numerical simulations. However, estimates of seismic response are subject to various sources of uncertainty, including modeling uncertainty. This research estimated the response of two full-scale structural specimens composed of a moment resisting frame, elastic spines, and force-limiting connections (FLC), which...

Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

Creator:: Herrmann, Joan F.
Abstract:: Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

Interaction of water waves and deformable bodies

Creator:: Broderick, Laurie L.
Abstract:: A time-domain model was developed to predict the fluid/structure interaction of a three-dimensional deformable body in a fluid domain subject to long-crested finite amplitude waves. These nonlinear waves induce transient motion in the body. In turn, the interaction of the body with the waves modifies the wave field, causing additional...

The activity and growth of a chlorophenol reductively dechlorinating soil culture in the presence of exogenous hydrogen

Creator:: Lotrario, Joseph Bryce
Abstract:: The addition of exogenously supplied hydrogen stimulates PCP reductive dechlorination and increases bacterial growth. While research focuses mainly on pure cultures, few exist capable of aryl reductive dechlorination, and few markers exist to identify reductively dechlorinating bacteria within mixed cultures. Furthermore, most active bioremediation projects stimulate mixed cultures of native...

Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

Creator:: Kao, Yeoung Ting
Abstract:: Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

Startup and performance of a gas-permeable-membrane-supported (GPMS) biofilm system using a mixed culture of methylotrophs to degrade methylene chloride, chloroform, and carbon tetrachloride

Creator:: Ely, Roger L.
Abstract:: The methane monooxygenase (MMO) enzyme, used by methylotrophs to oxidize methane, has been shown to possess quite broad substrate specificity, being able to oxidize many organic compounds including n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and heterocyclic compounds. In this research, it was sought to determine whether a gas-permeable-membrane-supported (GPMS) biofilm...

Evaluation of the environmental conditioning system as a water sensitivity test for asphalt concrete mixtures

Creator:: Allen, Wendy L.
Abstract:: The Environmental Conditioning System (ECS) was designed to evaluate the water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...
