A Differential Absorption Model For Remote Sensing Of Atmospheric Pressure, Shivam J. Shah

Electrical & Computer Engineering Theses & Dissertations

The goal of the project is to develop and test a "model based" radar processing strategy that is compatible with the concept of a "cognitive radar". The basic approach will be to develop a cognitive radar algorithm (genetic algorithm) based on the capabilities of an existing commercially available Software Radio. While the focus of this effort is the development of a candidate approach for genetic algorithm, the longer term goal would be to implement the approach using this software radio technology to provide a low cost radar processor. The proposed technology would use differential absorption radar working at the 50-56 …

Gis Applications For Coal Mine Subsidence In The State Of Colorado, Charles J. Strickler

Geography and the Environment: Graduate Student Capstones

The state of Colorado has an extensive history of subsurface coal mining. Due to the widespread extraction of coal, numerous subsidence events have occurred, causing both costly and potentially dangerous conditions. The two most common types of underground coal mines in Colorado are slope and shaft mines, which are prone to roof collapse that can propagate to the surface in the form of sinkholes and troughs. Sinkholes and troughs can occur over prolonged periods of time or as instantaneous events, which may leave landowners little reaction time and expensive repairs. As of January 2010, no spatial database existed that covered …

Using Gis To Determine Wind Harvesting Potential To Help Offset Boulder County's Yearly Energy Usage To Become A More Sustainable County, Pete Coventry

Geography and the Environment: Graduate Student Capstones

This project focuses on Boulder County, Colorado as a case study to demonstrate how a Geographic Information System (GIS) can identify potential wind harvesting areas. A step by step demonstration will illustrate the steps needed to determine such harvesting areas and their wind potential. Once potential wind harvesting areas have been identified, concluding analysis will determine the amount of energy generated in efforts to offset current energy use. Harvesting wind has dated back to the 7^th century and is looked at as a mature technology (Edwards 2003). Over the past few decades, public attitudes towards wind harvesting is becoming …

Creating A Habitat Suitability Index Model For Argali Sheep (Ovis Ammon), And Siberian Ibex (Capra Sibirica) In Ikh Nartin Reserve, Mongolia, Nanette Bragin

Geography and the Environment: Graduate Student Capstones

Mongolia is a country with a park system of protected areas, preserving native flora and fauna. In order to inform decision makers about the status of endangered species and park land health, two species of concern, the Argali sheep (Ovis ammon) and Siberian ibex Capra siberica) in the Ikh Nart Reserve in Mongolia were studied. A Habitat Suitability Index Model was developed to study the Argali and ibex habitat preference and discern if the reserve and core zone offer optimal habitat. A total of 57 animals were examined, creating 95% and 50% home range kernels, and minimum convex polygons. The …

Beyul Khumbu: Sherpa Constructions Of A Sacred Landscape, Lindsay Ann Skog

Dissertations and Theses

Khumbu, part of Sagarmatha (Mt. Everest) National Park in eastern Nepal and an UNESCO World Heritage site, is home to the Sherpa people, ethnic Tibetan Buddhists who migrated to the region more than 500 years ago. Sherpas animate the landscape with localized water, tree, rock, and land spirits, identify sacred mountains, mainly associated with the Bönpo and Tibetan yullha traditions, and some view the landscape as a beyul, a sacred place and hidden valley protecting Buddhist people and beliefs in times of turmoil and need. These beliefs protect the natural environment through religious practices and taboos against environmentally harmful …

Susceptibility Modeling And Mission Flight Route Optimization In A Low Threat, Combat Environment, Brett J. Machovina

Electronic Theses and Dissertations

Movement and transportation systems are a primary topic in the study of humans and their relationship with the environment. Only a few modes of transportation allow for nearly full freedom of movement that is unconstrained by rigid nodes and networks. Individual human travel (walking, climbing, swimming, etc.) is one example while rotorcraft travel is another. Although other criteria constrain movement, independence from a network allows for a unique examination of human spatial decision-making and choice behavior. This research analyzes helicopter flight route planning in a low threat combat environment with respect to geography. The particular problem addressed, which ultimately concerns …

Treatment Of Displaced Indigenous Populations In Two Large Hydro Projects In Panama, Mary Finley-Brook, Curtis Thomas

Geography and the Environment Faculty Publications

The World Commission on Dams provided an analytical overview of the cumulative effects of years of dam development. A lack of commitment or capacity to cope with displacement or to consider the civil rights of, or risks to, displaced people led to the impoverishment and suffering of tens of millions and growing opposition to dams by affected communities worldwide. However, after the WCD, little has changed for the better in terms of resettlement policies. In fact, the standards of key agencies, like the Asian Development Bank, have been lowered and diluted compared to prior policies. Dam-induced development and displacement are …

Lidar Remote Sensing Variables Predict Breeding Habitat Of A Neotropical Migrant Bird, Scott J. Goetz, Daniel Steinberg, Matthew G. G. Betts, Richard T. Holmes

Dartmouth Scholarship

A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the northeastern United States. We apply these results to predict the breeding habitat quality, an indicator of reproductive output of a well-studied Neotropical migrant songbird, the Black-throated Blue Warbler (Dendroica caerulescens). We found that using canopy vertical structure metrics provided unique information for models of habitat quality and spatial patterns of …

Examining The Effects Of Climate Change And Urban Development On Water Demand: A Multi-Scale Analysis Of Future Water Demand In Hillsboro, Oregon, Lily Arielle House-Peters

Dissertations and Theses

In the Portland, Oregon, metropolitan area, suburban cities such as Hillsboro are projected to grow as people seek affordable housing near a rapidly growing metropolis. This thesis examines the combined impact of climate change and urban development on both neighborhood and municipal scale residential water demand in Hillsboro, Oregon. I use two models, a surface energy balance model, Local-scale Urban Meteorological Parameterization Scheme (LUMPS), and a system dynamics model, CCDomestic, to investigate changes in residential water demand in the 2040s at two distinct spatial scales, the neighborhood and the municipality. I calibrate and validate each model to the reference period …

Tracking Sources Of Enrollment At Etsu Through The Use Of Gis., Charles Thomas Phillips

The objective of this research is to look at fall freshmen enrollment data for East Tennessee State University and see if patterns in the enrollment exist. This paper focuses on fall freshmen enrollment during the years 1997, 2002, and 2007 at ETSU. Once the data were gathered, they were mapped and statistically analyzed using geographic information systems (GIS) and statistical analysis software.

Many things were learned from the GIS maps created and statistical analysis. First, the maps showed that from 1997 to 2007, ETSU's enrollment became more consolidated in the East Tennessee region and moved westward into Middle and Western …

Are Residents Who Are Displaced By Gentrification Better Or Worse Off After Relocating?, Alice M. Anigacz

Economics Honors Projects

This honors thesis examines how individuals displaced by gentrification fare after relocation, with changes in wage and income as the primary measures of well-being. Geo-coded Panel Study of Income Dynamics data is used in conjunction with decennial census tract-level neighborhood data to evaluate nationwide occurrences of gentrification and their effects on the displaced between 1990 and 1995, with a focus on whether changing neighborhood effects can account for the change in well-being. Standard OLS regressions not accounting for neighborhood effects find that compared to a nationwide sample, a sample of movers, and a sample of displaced residents, residents displaced specifically …

At The Intersection Of Neoliberal Development, Scarce Resources, And Human Rights: Enforcing The Right To Water In South Africa, Elizabeth A. Larson

International Studies Honors Projects

The competing ideals of international human rights and global economic neoliberalism come into conflict when developing countries try to enforce socio-economic rights. This paper explores the intersection of economic globalization and the enforcement of 2nd generation human rights. The focus of this exploration is the right to water in South Africa, specifically the recent Constitutional Court case Mazibuko v City of Johannesburg. While a right to water can be constructed at the international level, the right disappears in the face of neoliberal development measures such as those that are instituted by democratic governments in developing nations faced with limited resources.

The Places Of Birth: Navigating Risk, Control, And Choice, Hannah E. Emple

Geography Honors Projects

Through qualitative research in the Twin Cities, Minnesota and a literature review grounded in health and feminist geography, this paper analyzes how women, their families, and health care providers view and navigate places of birth. Over four million births occur annually in the United States, making birth the most common reason for hospitalization of women. Although 99% of women in the U.S. give birth in hospitals, a small but vocal minority seek alternative places to birth – primarily at home. Where to give birth is a contested subject infused with social and political significance. I suggest that place is highly …

Assessing The Efficacy Of Modis Satellite-Derived Start Of Growing Season For Jurisdictional Determination Of East Texas Bottomland Hardwood Wetlands, Karen Malone, Hans Michael Williams, I-Kuai Hung, Daniel Unger

Faculty Publications

Introduction: Crucial to the determination of a jurisdictional wetland is the definition of “growing season”. Satellite imagery is being utilized in other ecological applications, but is lagging in wetland growing season determination. Both cost and temporal limitations historically have restrained use of satellite imagery in assessing the start up of the growing season. Multiple commercial satellites are available that provide high resolution imagery, but the cost are prohibitive for most studies. The National Aeronautics and Space Administration (NASA) and the U.S. Geological Survey (USGS) jointly manage the Landsat and the Moderate-resolution Imaging Spectroradiometer (MODIS) satellite programs. Landsat Enhanced Thematic Mapper …

Analysis Of Fresh Water Resources At The Line Hole Well Field, San Salvador Island, The Bahamas, Scot Allan Russell Jr.

Masters Theses & Specialist Projects

A major economic constraint in the Bahamas, and other small carbonates islands world-wide, is the lack of fresh water resources. To combat these socio-economic problems on San Salvador Island I sought to gain a more detailed understanding of the extent, behavior, and controls on the island’s fresh-water lens. DC electrical resistivity tomography and time-series geochemical data are used to study the fresh water lens at the Line Hole well field. Electrical Resistivity profiles are used to image the extent of fresh water resources. Time-series geochemical data provide information on the behavior of the fresh water resources as a function of …

Geographic Information System Analysis Of Changing Demographic Patterns And Ethnic Restaurant Locations In Bowling Green, Kentucky, 1940-2005, Shwu-Jing Jeng

Masters Theses & Specialist Projects

The geography of food has been a popular subject for researchers and scholars who have explored the representative foods of a given region in reference to the area’s cultural identity. Food plays an important role in the development of individual cultures and civilization. Food consumption and dining habits usually reflect individuals’ location, cultural and individual identity, accessibility to food and heritage. United States is a country often called a “melting pot society.” Immigrants in the United States comprise over eight percent of the population, and various ethnic groups have reshaped American society with their unique cultures and foodways.

Spatial Analysis Of Urbanization In The Salt Lake Valley: An Urban Ecosystem Perspective, John H. Lowry Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because urban areas comprise a variety of biotic (e.g. people, trees) and abiotic (e.g. streets, water) components that interact and are often interdependent upon one another, it is helpful to study urban areas as urban ecosystems.

Our goal in Chapter 2 is to measure and quantify the spatial and demographic structure of the urbanized portion of Salt Lake County, Utah. We use 18 metrics from four broad categories (density, centrality, accessibility, and neighborhood mix) to measure urban form for three age-based residential neighborhood types. Using analysis of variance (ANOVA) we test for differences in mean values for the 18 …

Object-Based Segmentation And Classification Of One Meter Imagery For Use In Forest Management Plans, W. Kevin Wells

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research developed an ArcGIS Python model that extracts polygons from aerial imagery and assigns each polygon a vegetation type based on a modified set of landcover classes from the Southwest Regional Gap Analysis Project. The model showed an ability to generate polygons that accurately represent vegetation community boundaries across a large landscape. The model is for use by the Utah Division of Forestry, Fire, and State Lands to assist in the preparation of forest management plans. The model was judged useful because it was easy to use, it met a designated 50% threshold of useable polygons, and it met …

Modeling Bark Beetle Outbreak And Fire Interactions In Western U.S. Forests And The Invasion Potential Of An Invasive Puerto Rican Frog In Hawaii Using Remote Sensing Data, Simon A. Bisrat

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I used Moderate-Resolution Imaging Spectroradiometer (MODIS) imagery to answer two ecological questions. In the first project, I investigated the interactions between bark beetle-caused tree mortality and fire occurrence in western U.S. forests. I used remotely sensed fire data detected by MODIS satellite and bark beetle-caused tree mortality data. I tested the hypothesis that there is an increased probability of fire incidence in bark beetle-damaged forests compared to healthy forests using conditional probability modeling across the national forests of the western U.S. regardless of forest type. My results did not show a consistent pattern (increase or decrease of conditional probability of …

Fire Effects On Wildlife In Tallgrass Prairie, Maria Gaetani, Kayla Cook, Sherry Leis

United States National Park Service: Publications

Abstract

In the tallgrass prairie region of North America, grasslands are often burned on a rotational schedule to prevent the encroachment of woody species and maintain the vigor of plant communities. Although prescribed fire practitioners often consider the effects of fire on plant communities, the effects of fire on wildlife are also important. Practitioners as well as park visitors inquire about the effects of fire on birds, deer, and other animals of interest. Many wildlife species focus on vegetation structure in choosing suitable habitats, and fire can temporarily alter that structure. Wildlife species have varying habitat needs, and therefore, a …

Accessibility In The Syracuse Food Desert, Amory Hillengas

Renée Crown University Honors Thesis Projects - All

Food insecurity is uncertain access to nutritious food. It is a social justice issue influenced by geographic and demographic factors. Low-income and minority individuals are more prone to be affected by food insecurity. One way is that they may live in food deserts, places where there is limited access to nutritious food sources. It is unjust for anyone to have inadequate access to nutritious food. This study investigated this premise in Syracuse, New York. The selected study area was composed of zip codes 13205, 13207, 13202 and 13210. The food sources for these regions were identified through the database Reference …

The Commodification Of The Modern Black Man: Examining The Effect Of Drug Law On The New York State Prison Industrial Complex, Alexis Kinney

Renée Crown University Honors Thesis Projects - All

This Capstone project examines the effect of New York State’s prison industrial complex on local economies. The prison industrial complex is a system of imprisonment that, through various methods, transforms prisoners into commodities. The complex involves endorsing legislation to create more crimes and longer sentences for those crimes, thus increasing the number, and term length, of incarcerated citizens. In New York, the creation of the Rockefeller drug laws resulted in a revitalized diligence in the war against drugs, leading to the promotion of prisoner-based upstate economies. Through engagement with United States drugs laws, historical accounts of drug use and addiction, …

Sustainable Syracuse: A Community Revitalization Initiative Through Green Mapping, Morgan Leykam

Renée Crown University Honors Thesis Projects - All

A reinvention of Syracuse’s identity is taking place. A once industrial hub that could tout the Eerie Canal as its central lifeline and Onondaga Lake as a popular, American vacation spot has found itself fighting for two major development goals: sustainability and redeveloping low-income neighborhoods. “Creative city” development models are gaining popularity as America moves from manufacturing to service-based industries. But creative cities cannot be established using top-down approaches. When a creative city is built by the people who live in it, their passion comes through in the city’s image. What is perceived by visitors is a young, vibrant community …
