Ocean Surface Maps From Blending Disparate Data Through Normal Mode Analysis
… The NMA blending process is described, and surface maps of velocity and convergence are produced. Using statistical and qualitative techniques, the NMA generated “nowcasts” are analyzed to determine the significant modes applicable to varying oceanographic situations. Fundamental guidance …

Geology as a Georegional Influence on Quercus Fagaceae Distribution in Denton and Coke Counties of Central and North Central Texas and Choctaw County of Southeastern Oklahoma, Using GIS as an Analytical Tool.
… ESRI's ArcGis and ArcMap was used to create surface maps for Denton and Coke Counties, Texas and Choctaw County, Oklahoma. Attribute tables generated in GIS were exported into a spreadsheet software program and frequency tables were created for every formation and soil order in the tri-county …

The solar corona: modeled, discretized, visualized
… corona---the plasma that extends from the solar surface into space. These coronal fibers can be modeled as magnetic filaments whose shape is governed by the magnetohydrostatic equation. The first goal of this dissertation is to rigorously establish and derive the mathematical model to solve this …

Estimating Impervious Surface Cover in Flathead County, Montana
… that are unique to that area. Impervious surfaces can serve as a suitable proxy for tracking the spread of various anthropogenic influences on an ecosystem; it impacts groundwater recharge, increases overall surface runoff as well as pollution and sediment load, and fragments landscapes. …

Evaluation of Groundwater Quality in Paleozoic Aquifers Using GIS Techniques, Central Texas
… trending normal faults. Potentiometric surface maps determined the direction of groundwater flow and specific monitoring wells along flowpaths for analyses. Chemical distribution maps processed by ArcGIS 10.2 provided an aerial view of major constituents during each timeline. This …

On the utilization of Simultaneous Localization and Mapping(SLAM) along with vehicle dynamics in Mobile Road Mapping Systems
… to the growing demand for high definition road surface maps in wide ranging applications from pavement management to autonomous vehicle testing. The focus of this research work is to improve the accuracy of MRMS by using the principles of Simultaneous Localization and Mapping (SLAM). First a …

Quantifying groundwater discharge using thermal imagery and conventional groundwater exploration techniques for estimating the nitrogen loading to a meso-scale inland estuary
… quality, specific discharge, and piezometric surface maps in the summer of 2001. Monitoring wells upgradient of the Great Bay were analyzed for nitrogen as an indicator of potential discharge source waters. Total groundwater discharge to the estuary was calculated as 24.2 cubic feet per second …

Land Cover and Impervious Surface Mapping Using Multispectral Airborne Laser Scanner Data
Impervious surfaces are land covers that do not allow water penetration. Water runoff from impervious surfaces can cause major flooding in extreme climates; therefore, mapping such surface covers in urban areas is of great importance for water resources, climatology, and urban studies. Automated …

Fourier Transform Interferometry for 3D Mapping of Rough and Discontinuous Surfaces
… existing optical techniques for non-contact 3D surface mapping, Fourier Transform Interferometry (FTI) is the method that most elegantly combines simplicity with high speed and high resolution. FTI generates continuous-phase surface maps from a projected optical interference pattern, which is …

Investigations of Structure / Property Interrelationships of Organic Thin Films Using Scanning Probe Microscopy and Nanolithography
Studies of the surface assembly and molecular organization of organic thin films were studied using scanning probe microscopy (SPM) and scanning probe lithography (SPL). Systems of organic thin films such as n-alkanethiols and pyridyl functionalized porphyrins were characterized at the molecular …

A camcorder-based rapid mapping system
… Retroreflective targets were placed along the surface of the wreck to tie the imagery together. This thesis reports on the mapping of one of the sections of the shipwreck, and discusses the use of video imagery for the production of surface maps.

Quantitative measurement of spatial accessibility to locations both in urban and peri-urban environments
… origins to the nearest destinations. Trend surface maps (suitability maps) were produced, and they showed the locations of potential populations that the parcel pickup points are not available. The maximum number of customers per site and the pickup points needed to cover an area were …

Stochastic Terrain and Soil Modeling for Off-Road Mobility Studies
… terrain profiles in two dimensions (i.e., surface maps). Certain assumptions are made for the values of the model coefficients to obtain the terrain profile through the fast computational approach described, while preserving the stochastic properties of the original terrain topology. The …

Accumulating delivered dose to the rectum to improve toxicity prediction in prostate radiotherapy
… planned dose. Analysis was performed using dose surface maps (DSMs) of the rectal wall, allowing spatial aspects of dose to be retained during accumulation. A subsequent analysis on a separate cohort also found stronger links between delivered dose and GI toxicity, stool frequency, and bowel …
