Archaeological, Geophysical, And Geospatial Analysis At David Crockett Birthplace State Park, In Upper East Tennessee, Reagan Cornett
Electronic Theses and Dissertations
A geophysical survey was conducted at David Crockett Birthplace State Park (40GN205, 40GN12) using ground-penetrating radar (GPR) and magnetometry. The data indicated multiple levels of occupation that were investigated by Phase II and Phase III archaeological excavations. New cultural components were discovered, including the remnants of a Protohistoric Native American structure containing European glass trade beads and Middle Woodland artifacts that suggest trade with Hopewell groups from Ohio. A circular Archaic hearth was uncovered at one meter below surface and similar deep anomalies were seen in the GPR data at this level. A semi-automated object-based image analysis (OBIA) was implemented …

Potable Water Leakage Prediction And Detection Using Geospatial Analysis, Jacob Tittle
Electronic Theses and Dissertations
Due to increasing water treatment costs and conservation needs, traditional water loss analysis and acoustic leak detection methods are becoming heavily scrutinized by water utilities. This study explores water loss in Johnson City, Tennessee and how geospatial data analysis techniques improve water loss mitigation. This project uses sample water system pressure data and ordinary kriging spatial interpolation methods to identify leakage areas for further investigation. Analysis of existing geographic information system (GIS) water utility datasets with interpolated hydraulic grade values at sample water pressure points produce manageable survey areas that pinpoint areas with possible water leakage. Field detection methods, including …

Automation Of State Climate Office Processes & Products: Developing Efficient Approaches For Data Dissemination, Michael Shoop
Electronic Theses and Dissertations
State Climate Offices (SCO’s) in the United States are critical conduits for improving weather and climate data in local communities. Two states do not have a state-recognized SCO: Tennessee and Massachusetts. Efforts are underway at East Tennessee State University to develop the Tennessee Climate Office (TCO). Currently, climate services and products are severely lacking across Tennessee. This thesis provides an improved methodology for an existing TCO product and outlines the development of a new product using Python scripting. Daily storm reports within the monthly climate report are automated and a Weather Forecasts Hazard Index (WFHI) web application is developed. Both …
Native American Occupation Of The Singer-Hieronymus Site Complex: Developing Site History By Integrating Remote Sensing And Archaeological Excavation, Claiborne Sea
Electronic Theses and Dissertations
Located on a ridgetop in central Kentucky, the Singer-Hieronymus Site Complex consists of at least four Native American villages. The Native Americans who lived there are called the “Fort Ancient” by archaeologists. This study examined relationships between these villages, both spatially and temporally, to build a more complete history of site occupation. To do this, aerial imagery analysis, geophysical survey, and archaeological investigations were conducted. This research determined there were differences among villages in terms of their size, however other characteristics—internal village organization, village shape, radiometric dates, and material culture—overlapped significantly. Additionally, landscape-scale geophysical survey identified at least three potentially …
Tornado Density And Return Periods In The Southeastern United States: Communicating Risk And Vulnerability At The Regional And State Levels, Michelle Bradburn
Tornado Density And Return Periods In The Southeastern United States: Communicating Risk And Vulnerability At The Regional And State Levels, Michelle Bradburn
Electronic Theses and Dissertations
Tornado intensity and impacts vary drastically across space, thus spatial and statistical analyses were used to identify patterns of tornado severity in the Southeastern United States and to assess the vulnerability and estimated recurrence of tornadic activity. Records from the Storm Prediction Center's tornado database (1950-2014) were used to estimate kernel density to identify areas of high and low tornado frequency at both the regional- and state-scales. Return periods (2-year, 5-year, 10-year, 25-year, 50-year, and 100-year) were calculated at both scales as well using a composite score that included EF-scale magnitude, injury counts, and fatality counts. Results showed that the …
Aaaneurysm Outreach Screening Data And Emergency Healthcare Accessibility In Louisiana: Identifying High-Risk Populations For Targeted Interventions, Amy M. Poole
Electronic Theses and Dissertations
Abdominal aortic aneurysms are the third leading cause of sudden death in men 60 years and over. AAAneurysm Outreach provides free screenings to residents of Louisiana and beyond. Service areas were calculated for each AAAneurysm Outreach screening event location and stroke center. Data provided by the 2010 U.S. Census, the American Community Survey, and the Behavioral Risk Factor Surveillance System were used to describe demographics of the underserved populations and to identify high-risk areas for targeted interventions. Twenty-five percent of age-eligible Louisianans reside outside optimal drive-time-to-screening-event zones but within spatially clustered areas of increased prevalence rates. The maximum drive-time-to-treatment zones …
Evacuation And Shelter In Place Modeling For A Release Of Uranium Hexafluoride, Joseph B. Harris
Evacuation And Shelter In Place Modeling For A Release Of Uranium Hexafluoride, Joseph B. Harris
Electronic Theses and Dissertations
Evacuation and sheltering behaviors were modeled for a hypothetical release of uranium hexafluoride (UF6) from Nuclear Fuel Services (NFS) in Erwin, Tennessee. NFS down-blends weapons grade Cold War-era nuclear fuel material and processes highly-enriched uranium occasionally using UF6 onsite. Risk associated with a chemical release to the surrounding residential population was assessed by running 2 scenarios involving an airborne release of UF6 to compare evacuation and sheltering in place actions as effective survival strategies. Risk is minimal and evacuation is recommended for people within a 2-mile radius of the release point. Shelter in place actions are recommended for all critical …
Site Location Modeling And Prehistoric Rock Shelter Selection On The Upper Cumberland Plateau Of Tennessee, Lucinda M. Langston
Site Location Modeling And Prehistoric Rock Shelter Selection On The Upper Cumberland Plateau Of Tennessee, Lucinda M. Langston
Electronic Theses and Dissertations
Using data collected from 2 archaeological surveys of the Upper Cumberland Plateau (UCP), Pogue Creek Gorge and East Obey, a site location model was developed for prehistoric rock shelter occupation in the region. Further, the UCP model was used to explore factors related to differential site selection of rock shelters. Different from traditional approaches such as those that use (aspatial) logistic regression, the UCP model was developed using spatial logistic regression. However, models were also generated using other regression-based approaches in an effort to demonstrate the need for a spatial approach to archaeological site location modeling. Based on the UCP …
