Modeling Acoustic Scattering From The Seabed Using Transport Theory, Jorge Quijano, Lisa M. Zurk
Electrical and Computer Engineering Faculty Publications and Presentations
Radiative Transfer (RT) theory has established itself as an important tool for electromagnetic remote sensing in parallel plane geometries with random distributions of scatterers, and most recently it has also been proposed as a model for the propagation of elastic waves in layered ocean sediments. In this work the capabilities of this model are illustrated, as the RT method is used to predict backscattering strength from laboratory models of random media. The RT model is characterized by its flexibility on accommodating scatterers in a broad variety of sizes, shapes, and acoustic contrast relative to the background media. Additionally, this formulation …

China And Geography In The 21st Century: A Cultural (Geographical) Revolution?, Lily Kong
Research Collection School of Social Sciences
A noted Singapore-based cultural geographer and specialist on Asia reviews the recent emergence of cultural geographic research on and within China and the implications of China's rise for the study of 21st century cultural geography more broadly. She identifies six major issues modern China is confronting that, when addressed from a cultural geographical perspective, may both enhance an understanding of the country and reshape the practice of cultural geography as a subdiscipline: agricultural reform, economic reform, urban change, rural-urban migration and related social inequalities, the changing family structure, and environmental change. The author argues that if China's cultural geography is …

A decade and a half after Cosgrove and Jackson (1987) wrote their seminal piece on ‘new’ cultural geography, the discipline of geography has experienced a ‘cultural’ turn. Economic geography, for instance, has been infleected through perspectives that take on board cultural retheorisations (see Thrift and Olds, 1996; Thrift, 2000). Within urban studies, the acknowledgement of culture’s powers is not new (see, for example, Agnew et al., 1984). Yet, geographers scrutinising urban landscapes have moved the field, using some of the retheorised perspectives that Cosgrove and Jackson (1987) encapsulated. Of most pertinence to this volume is the retheorised notion of culture …

Object Discrimination Using A Multi-Wavelength Photonic Sensor, Kavitha Venkataraayan, Sreten Askraba, Kamal E. Alameh, Clifton L. Smith
International Cyber Resilience conference
A bench prototype photonic-based sensor for object discrimination is described. A combination module, which allows five laser diodes of different wavelengths to overlap and sequentially emit identically-polarised light beams through a common aperture, is presented. The key visible and infrared wavelengths are selected from sample objects spectral signatures. A cylindrical optical quasi-cavity structure is designed to generate 15 laser spots for each laser. The intensity of the reflected light from each spot is detected by a high speed line scan image sensor. Object discrimination is accomplished by calculating the slope values between selected wavelengths in the blue to infrared range.

Mapping In Philanthropy: Exploring The Use Of Mapping In Foundation Grantmaking, Jim Casey
Geography and the Environment: Graduate Student Capstones
Foundations provide grants to nonprofit organizations in our communities, who then provide services locally. Choosing which nonprofit to fund, and which not to fund is difficult. This study examines current uses and upcoming uses of mapping and Geographic Information Systems (GIS) as part of funding decisions made by foundations. Foundations engaged in strategic funding, especially that which targets specific populations are more likely to use GIS and geospatial analysis in funding decisions. Grantmaking in response to proposals requires less strategic analysis and calls for mapping much less by comparison. As a field, nationally foundations and nonprofits have identified many uses …

A Gis Model To Predict Feral Pig (Sus Scrofa) Habitat On Vandenberg Air Force Base, California, Brian Schnick
Geography and the Environment: Graduate Student Capstones
The applicable Natural Resource area of this project is animal control and wildlife management, as wild pigs can be quite destructive to landscapes (Campbell, et al., 2010) (McCann, et al., 2008). Geographic Information System (GIS) predictive models have proven to be useful in regards to other mammals (Travaini, et al., 2007), raptors (Bustamante, et al., 2004), and pest species such as locusts (van der Werf, et al., 2005). Pigs are often nocturnal and bed down in heavy cover, hindering direct observation. Additionally, Vandenberg Air Force Base (VAFB) encompasses over 400 square kilometers. Therefore, predictive modeling is an appropriate method for …

Developing Tornado Climatology In The Southern Great Plains Per Phases Of Prominent Oceanic Oscillations, Nicholas M. Fillo
Geography and the Environment: Graduate Student Capstones
Meteorologists are continually working toward a greater understanding of which atmospheric environments are most conducive for tornado development. This Capstone project analyzed tornado occurrences across Texas, Oklahoma, Arkansas and Louisiana during the period 1950 through 2009 to determine if any correlation exists between the location and frequency of tornado activity and the phases of the El Nino-Southern Oscillation, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation. While it was determined that no phase of any of the oscillations studied was significantly more dominant over the other(s) concerning frequency, this project does identify some spatial shifts in tornado activity depending …

Determining Heritage Oak Tree Susceptibility To Sudden Oak Death Using Gis Risk Analysis, Michelle M. Guzdek
Geography and the Environment: Graduate Student Capstones
Sudden Oak Death (SOD), caused by the pathogenic water mold Phytophthora ramorum, has killed hundreds of thousands of oak trees in the California coastal regions, with redwood-tanoak forests being hit the hardest (Shoemaker et al., 2007). The term “sudden oak death” is used to describe the disease, because of how rapidly the pathogen has killed otherwise healthy tanoaks, virtually in a matter of weeks (COMTF 2010). SOD was first reported in California in 1994 and is believed to have originated from infected nursery or ornamental plants, but the source has never been identified (Mascheretti et al. 2008).

Geography and Geology Faculty Proceedings & Presentations
A transect of sites has been established in North America and England as part of the Critical Zone Exploration Network (CZEN) to investigate the rates of soil formation across a climate gradient. Sites reported here are all underlain by an organic-poor, iron-rich Silurian-age shale, providing a constant parent material lithology from which soil is forming. This climosequence includes relatively cold and wet sites in Wales, New York and Pennsylvania, with temperature increasing to the south in Virginia, Tennessee and Alabama. Puerto Rico provides a warm/wet end member for the transect, although this site does not lie on the same shale …

'The Edge Of The Island': Neighborhood Identity And Evolving Community In 'Liminal Places', Gordon Douglas
Faculty Publications, Urban and Regional Planning
This paper examines the contemporary processes at work in urban areas without clear spatial identities that are simultaneously facing the challenges of cultural change and gentrification. I do so through the close analysis of one such ‘liminal place’ on Chicago’s West Side. I use the phrase ‘a community on the edge of the island’ to describe the area, inspired by an interview subject who referred to the tenuous search for a sort of ideal bohemian hipness as the need to stay as “close to the edge of the island” as possible without actually leaving it. Making use of ethnographic and …

The Global Project: Observing Geographic Literacy Obtained By Study Abroad Learning, Erin Joy Greunke
Masters Theses & Specialist Projects
One of the major debates regarding studying abroad concerns criticism that it lacks measurable and demonstrable learning outcomes and is usually viewed as less rigorous than other university courses (McKeown 2009). As one Western Kentucky University (WKU) faculty member noted when responding to the Faculty Attitudes Survey deployed for this project, all too often “too many study abroad experiences [are] little more than glorified fieldtrips.....” (Anonymous WKU Faculty Member, 2009, Appendix IV). While this may be the case, upon their return to the United States, students often say their study abroad experience proved life changing. The primary purpose of this …

The Multifunctional Transition In Australia’S Tropical Savannas: The Emergence Of Consumption, Protection And Indigenous Values, John Holmes
Aboriginal Policy Research Consortium International (APRCi)
As elsewhere in affluent, western nations, the direction, complexity and pace of rural change in Australia can be conceptualised as a multifunctional transition in which a variable mix of consumption and protection values has emerged, con- testing the former dominance of production values, and leading to greater com- plexity and heterogeneity in rural occupance at all scales. This transition has been explored in accessible, high-amenity landscapes driven by enhanced consumption values. Less attention has been directed to remote, marginal lands where a flimsy mode of productivist occupance can, in part, be displaced by alternative modes with the transitions being facilitated …

Preservation Ethics In The Case Of Nebraska's Nationally Registered Historic Properties, Darren Michael Adams
Department of Geography: Dissertations, Theses, and Student Research
This dissertation focuses on the National Register of Historic Places and considers the geographical implications of valuing particular historic sites over others. Certain historical sites will either gain or lose desirability from one era to the next, this dissertation identifies and explains three unique preservation ethical eras, and it maps the sites which were selected during those eras. These eras are the Settlement Era (1966–1975), the Commercial Architecture Era (1976–1991), and the Progressive Planning Era (1992–2010). The findings show that transformations in the program included an early phase when state authorities listed historical resources pertaining to the settlement of the …

Density Estimation And Adaptive Bandwidths: A Primer For Public Health Practitioners, Heather A. Carlos, Xun Shi, James Sargent, Susanne Tanski, Ethan M. Berke
Dartmouth Scholarship
Background: Geographic information systems have advanced the ability to both visualize and analyze point data. While point-based maps can be aggregated to differing areal units and examined at varying resolutions, two problems arise 1) the modifiable areal unit problem and 2) any corresponding data must be available both at the scale of analysis and in the same geographic units. Kernel density estimation (KDE) produces a smooth, continuous surface where each location in the study area is assigned a density value irrespective of arbitrary administrative boundaries. We review KDE, and introduce the technique of utilizing an adaptive bandwidth to address the …

Planning Policy And Public Perception In Small-Town Utah, Greg M. Platt
Theses and Dissertations
City growth policies codify community values and serve as the basis for enforcement of community standards. If these policies do not match resident preferences for growth, potential exists for communities to grow in ways which make the community undesirable. This thesis examines whether adopted city growth policies match resident preferences in small towns in Utah. Findings include a strong relationship between resident preferences and city leader preferences for growth. Also, city staffs are poor readers of public sentiment relative to growth and growth management. Some cities are more effective in enacting city policies to match resident attitudes towards growth than …

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 …

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 7th century and is looked at as a mature technology (Edwards 2003). Over the past few decades, public attitudes towards wind harvesting is becoming …
