Advancing Spatial Data Engineering and Analysis: Integrative Approaches with GIS, Statistical Modelling, and Deep Learning

Creator:: Krivova, Maria
Abstract:: Geospatial data analysis is a multifaceted discipline encompassing the collection, processing, and visualization of diverse datasets. It models and delineates the interactions of people, objects, and phenomena within geographical spaces and predicts patterns based on the relationships between different locations. Despite significant advancements in geospatial data engineering and analytics over...

Alternate Methods for the Extraction and Measurement of Pore Solution in Fresh Concrete

Creator:: Biever, Joseph
Abstract:: Knowledge of the pore solution composition and pore solution resistivity can be helpful for determining the durability of concrete structures. Most notably, pore solution resistivity can be used in the calculation of the formation factor of concrete, which is a ratio of the electrical resistivities of concrete and its pore...

Biodegradation of methyl tert-butyl ether (MTBE) and its breakdown products by propane and iso-pentane grown Mycobacterium vaccae and Graphium sp. : cometabolism, inhibition, kinetics, and modeling

Creator:: Martínez-Prado, Maria Adriana
Abstract:: Mycobacterium vaccae JOB5 and Graphium sp. were studied to evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its metabolites after growth on two different alkanes, propane and iso-pentane. Both cultures were capable of cometabolizing MTBE and the metabolites, tert-butyl formate (TBF) and tert-butyl alcohol (TBA). MTBE, TBF, and...

Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

Creator:: Converse, Jordan D.
Abstract:: With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

Deterministic and stochastic control of nonlinear oscillations in ocean structural systems

Creator:: King, Paul E.
Abstract:: Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....

Nonlinear dynamic response of bottom-land deep ocean pipelines

Creator:: Zimmerman, Michael E.
Abstract:: A finite element formulation is developed for the prediction of the large displacement response of pipelines which are placed upon irregularly contoured marine sediments and are subsequently subjected to episodic hydrodynamic loads. The equations of motion during each episode of extreme wave activity are obtained from a variational form of...

Finite amplitude deep water waves : a comparison of theoretical and experimental kinematics and dynamics

Creator:: Jensen, Robert E.
Abstract:: Problems associated with quantification of deep water wave kinematics and dynamics are examined. Summaries of Stokes' theory and Dean's stream function theory are reported. A computer algorithm is developed to solve the hydrodynamic characteristics for Stokes' fifth and third order and linear theories. Tests are initiated to verify the results...

Diffusion of selected radionuclides through Hanford Trench 8 soil material

Creator:: Schwab, Kristen E.
Abstract:: Shallow land burial in vadose zone sediment at the Hanford Site in Washington is being considered for the disposal of Category 3 low-level waste. A series of column experiments were conducted to evaluate and model the performance of the soil surrounding the trench encasement material for iodine-129 and technetium-99 by...

Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

Creator:: Nichols, William E.
Abstract:: The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

Interstitial fluid mixing in estuarine benthic sediments

Creator:: Boyce, Allen R.
Abstract:: A method of measuring interstitial fluid mixing rates for evaluation of exchange between pore water of estuarine benthic sediments and the overlying water in a bay is presented. Pore water movement is monitored by reducing conductivity of the interstitial fluid within a zone of the benthic sediment to a depth...
