Utilizing Landsat Tm And Oli In Predicting Oncomelania Hupensis Habitats Around Poyang Lake Before And After Three Gorges Dam Completion, Stephanie L. Mccracken

Honors Theses

Schistosomiasis is a parasitic disease caused by the Schistomsoma japonicum flatworm that utilizes the Oncomelania hupensis snail as an intermediate agent. In the People’s Republic of China, these amphibious snails contaminate freshwater systems infecting humans, bovines, and other mammals and have caused significant morbidity for over two thousand years (Wertheim, et al. 2012; Zhang, et al. 2012.) The gravity of this disease prompted the national government to initiate sizable public health programs, such as the World Bank Loan Project (WBLP.) In spite of WBLP's achievements, in 2004, after this program ended, a national survey acknowledged a resurgence of schistosomiasis in …

E-Darwin: Energy Aware Disaster Recovery Network Using Wifi Tethering, Mayank Raj, Krishna Kant, Sajal K. Das

Computer Science Faculty Research & Creative Works

In this paper, we propose a novel architecture called Energy Aware Disaster Recovery Network using Wi-Fi Tethering (E-DARWIN). The underlying idea is to make use of Wi-Fi Tethering technology ubiquitously available on wireless devices, like smartphones and tablets, to set up an ad hoc network for data collection in disaster scenarios. To this end, we design novel mechanisms, which aid in autonomous creation of the ad hoc network, distribution of data capturing task among the devices, and collection of data with minimum delay. Specifically, we design and implement a distributed coalition formation game for distributing the data capturing task among …

Hepatitis B, C Virus And Hiv Co-Infection Among Reported Female Cases In South Carolina, 2004 - 2011: An Epidemiological Analysis Of Pregnancy Outcomes, Afiba Manza-Azele Agovi

Theses and Dissertations

HIV, hepatitis B and C virus (HBV, HCV) are three of the most common blood-borne infections and they continue to be a major public health problem in the United States (US) and globally. It is not well understood if maternal infection with either HBV or HCV has an adverse impact on pregnancy outcomes as findings from previous studies have provided some mixed results. The overall goal of this study was to assess the risk of preterm birth, low birth weight (LBW), small for gestational age (SGA) and admission into neonatal intensive care unit (NICU) for babies born to HBV- and …

Landscape Epidemiology And Machine Learning: A Geospatial Approach To Modeling West Nile Virus Risk In The United States, Sean Gregory Young

Graduate Theses and Dissertations

The complex interactions between human health and the physical landscape and environment have been recognized, if not fully understood, since the ancient Greeks. Landscape epidemiology, sometimes called spatial epidemiology, is a sub-discipline of medical geography that uses environmental conditions as explanatory variables in the study of disease or other health phenomena. This theory suggests that pathogenic organisms (whether germs or larger vector and host species) are subject to environmental conditions that can be observed on the landscape, and by identifying where such organisms are likely to exist, areas at greatest risk of the disease can be derived. Machine learning is …

Coffee Markets, Smallholder Credit, And Landscape Change In The Bolaven Plateau Region, Laos, Matthew Toro

Open Access Theses

This thesis analyzes relationships between global coffee prices, international development schemes, local trading and credit systems, and landscape dynamics in the Bolaven Plateau region of southern Laos. The region is a complex and rapidly changing resource space serving principally as the productive, socio-ecological base of the Lao coffee commodity chain. Fieldwork conducted there in 2009 entailed in-depth interviews and quasi-survey semi-structured interviews. These latter interviews yielded a database of 503 detailed loan/debt histories for 192 coffee smallholder households between 1987 and 2008. These data reveal a socio-economically exploitative cycle of coffee production, chronic indebtedness, and poverty at the base of …

The Historical, Present, And Future Role Of Veterinarians In One Health, Samantha E.J. Gibbs, Paul J. Gibbs

United States Fish and Wildlife Service: Publications

The renewed interest in the concept of One Health has occurred as a result of the increased emergence of zoonotic infectious diseases over the past decade. The subsequent impacts of these diseases on human, livestock, and wildlife health, as well as the economic effects, have given international health organizations and national governments a greater appreciation of the importance of collaborative efforts in solving health problems. The One Health concept is not new, but under its umbrella, a new generation of veterinarians, physicians, ecologists, biologists, and social scientists is shaping the concept in novel ways. This has led to increased support …

Use Of Environmental Isotope Tracer And Gis Techniques To Estimate Basin Recharge, Abdulganiu A.A. Odunmbaku

Open Access Theses & Dissertations

The extensive use of ground water only began with the advances in pumping technology at the early portion of 20th Century. Groundwater provides the majority of fresh water supply for municipal, agricultural and industrial uses, primarily because of little to no treatment it requires. Estimating the volume of groundwater available in a basin is a daunting task, and no accurate measurements can be made. Usually water budgets and simulation models are primarily used to estimate the volume of water in a basin.

Precipitation, land surface cover and subsurface geology are factors that affect recharge; these factors affect percolation which invariably …

Comparative Analysis Of Distribution And Abundance Of West Nile And Eastern Equine Encephalomyelitis Virus Vectors In Suffolk County, New York, Using Human Population Density And Land Use/Cover Data, I. Rochlin, K. Harding, Howard S. Ginsberg, S. R. Campbell

Plant Sciences and Entomology Faculty Publications

Five years of CDC light trap data from Suffolk County, NY, were analyzed to compare the applicability of human population density (HPD) and land use/cover (LUC) classification systems to describe mosquito abundance and to determine whether certain mosquito species of medical importance tend to be more common in urban (defined by HPD) or residential (defined by LUC) areas. Eleven study sites were categorized as urban or rural using U.S. Census Bureau data and by LUC types using geographic information systems (GISs). Abundance and percent composition of nine mosquito taxa, all known or potential vectors of arboviruses, were analyzed to determine …

Identifying And Explaining Map Quality Through Provenance: A User Study, Nicholas Ricky Del Rio, Paulo Pinheiro Da Silva

Departmental Technical Reports (CS)

Applications deployed on cyber-infrastructures often rely on multiple data sources and distributed compute resources to access, process, and derive results. When application results are maps, it is possible that non-intentional imperfections can get introduced into the map generation processes because of several reasons including the use of low quality datasets, use of data filtering techniques incompatible for the kind of map to be generated, or even the use of inappropriate mapping parameters, e.g., low-resolution gridding parameters. Without some means for accessing and visualizing the provenance associated with map generation processes, i.e., metadata about information sources and methods used to derive …

Molecular And Functional Characterization Of Bacterial Communities In Organic Farm And Pasture Soils, Sherie L. Edenborn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Culture-dependent denaturing gradient gel electrophoresis (CD DGGE) fingerprinting of the 16S rRNA gene was developed to characterize mixed soil bacterial communities recovered on agar plates. CD DGGE analyses resulted in clear banding patterns of sufficient complexity (16--32 major bands) and reproducibility to investigate differences in bacterial communities in silt loam soils. Replicate CD DGGE profiles from plates inoculated with less-dilute samples (10 -3) had a higher band count and were more similar (72--77%) than profiles from more-dilute samples (51--61%). When CD DGGE fingerprints were compared to profiles constructed from 16S rRNA genes obtained from culture-independent clone libraries (CB DGGE profiles) …

An Interpolation Method For Stream Habitat Assessments With Reference To The Crystal Darter, Kenneth Richard Sheehan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Crystallaria asprella spp. (Elk River crystal darter) is documented only in Elk River, West Virginia. Little life history detail is known about this lotic, benthic-dependent species. Previous studies have led to a very basic understanding of the use of depth, flow and substrate of the crystal darter (Crystallaria asprella), and less is known about the Elk River crystal darter. Due to substrate-specificity in crystal darters (which reportedly bury in sand), a study concerning benthic stream habitat modeling was undertaken. Substrate and depth modeling using >5% of an area sampled at a resolution of 0.093 m2 square spatial data in a …

Using Expert Knowledge In Solving The Seismic Inverse Problem, Matthew G. Averill, Kate Miller, George R. Keller, Vladik Kreinovich, Roberto Araiza, Scott A. Starks

Departmental Technical Reports (CS)

For many practical applications, it it important to solve the seismic inverse problem, i.e., to measure seismic travel times and reconstruct velocities at different depths from this data. The existing algorithms for solving the seismic inverse problem often take too long and/or produce un-physical results -- because they do not take into account the knowledge of geophysicist experts. In this paper, we analyze how expert knowledge can be used in solving the seismic inverse problem.

Towards Secure Cyberinfrastructure For Sharing Border Information, Ann Q. Gates, Vladik Kreinovich, Luc Longpre, Paulo Pinheiro Da Silva, Randy G. Keller

Departmental Technical Reports (CS)

In many border-related issues ranging from economic collaboration to border security, it is extremely important that bordering countries share information. One reason why such sharing is difficult is that different countries use different information formats and data structures. It is therefore desirable to design infrastructure to facilitate this information sharing.

UTEP is a lead institution in a similar NSF-sponsored multi-million geoinformatics project, whose goal is to combine diverse and complex geophysical and geographical data stored in different formats and data structures. We describe our experience in using and developing related web service techniques, and we explain how this experience can …

Geon: Geophysical Data Add The 3rd Dimension In Geospatial Studies, R. Aldouri, George R. Keller, Ann Q. Gates, J. Rasillo, Leonardo Salayandia, Vladik Kreinovich, John M. Seeley, P. Taylor, S. Holloway

Departmental Technical Reports (CS)

A major trend in GIS is the addition of subsurface information to provide a 3-D perspective on data. Geophysical data provide information about subsurface structures and conditions, but require considerable analysis. The 4-D emphasis with the GEON projects has required the development of many sophisticated tools to allow users to utilize geophysical datasets that will be available on the GEON grid. Our group has created tools that will allow users to search new gravity and magnetic databases of the entire U.S. These tools will extract specific records from an Oracle database, and display the points over a map, grid and …

Developing Risk Assessment Maps For Schistosoma Haematobium In Kenya Based On Climate Grids And Remotely Sensed Data, Kelsey Lee Mcnally

LSU Master's Theses

It is important to be able to predict the potential spread of water borne diseases when building dams or redirecting rivers. This study was designed to test whether the use of a growing degree day (GDD) climate model and remotely sensed data (RS) within a geographic information system (GIS), could be used to predict both the distribution and severity of Schistosoma haematobium. Growing degree days are defined as the number of degrees centigrade over the minimum temperature required for development. The base temperature and the number of GDD required to complete one generation varies for each species. A monthly climate …
