Creating A Canonical Scientific And Technical Information Classification System For Ncstrl+, Melissa E. Tiffany, Michael L. Nelson

Computer Science Faculty Publications

The purpose of this paper is to describe the new subject classification system for the NCSTRL+ project. NCSTRL+ is a canonical digital library (DL) based on the Networked Computer Science Technical Report Library (NCSTRL). The current NCSTRL+ classification system uses the NASA Scientific and Technical (STI) subject classifications, which has a bias towards the aerospace, aeronautics, and engineering disciplines. Examination of other scientific and technical information classification systems showed similar discipline-centric weaknesses. Traditional, library-oriented classification systems represented all disciplines, but were too generalized to serve the needs of a scientific and technically oriented digital library. Lack of a suitable existing …

The Birds And Habitat Of Kings Park, Bradley W. Cox

Theses : Honours

Kings Park is a large urban park in the centre of Perth with extensive areas of semi-natural bushland. The park is an important refuge for birds in the metropolitan area but is losing species through habitat disturbance. Understanding the way in which birds are related to their habitat helps to understand the effect of habitat disturbance on the bird community. The aim of this project was to generate guidelines which will aid in the management and conservation of birds in the park, through an understanding of the relationship of the birds to their habitat. The avifauna and various habitat factors …

Trends. Some Security Lessons From Kyoto, Ibpp Editor

International Bulletin of Political Psychology

The author discusses how "the environment" is no longer a fringe Issue championed by starry-eyed dreamers and psychodynamic deviants, and perennial misfits who have little understanding of or orientation to reality. In fact, the relevance of "the environment" for policies of political security has become quite significant.

Mathematical Modeling Of Convective Heat Transfer In Mammoth Cave, Jonathan Jernigan

Masters Theses & Specialist Projects

Around two centuries ago, changes were made to the entrances of Mammoth Cave and its passages. Today the Historic Entrance to Mammoth Cave is enlarged and the passage just beyond the entrance known as Houchins' Narrows has been cleared of rubble and filled with sediments. These enlargements have resulted in an increase in airflow throughout the Historic Section of the cave causing environmental conditions such as air temperature and airflow to fluctuate. These fluctuations have negatively impacted inhabitants and contents of the cave system. To restore natural conditions within the cave, Science and Resource Management personnel at Mammoth Cave National …

The Use Of Gis To Delineate Potential Urban Deer Habitat, David M. Kocka, Frederick M. Garst

Wildlife Damage Management Conference

Overabundant deer herds in urban environments often require new and creative approaches to properly evaluate the situation and gain support for population management. To determine potential white-tailed deer (Odocoileus virginianus) habitat for the Harrisonburg, Virginia, Deer Task Force, a geographic information systems (GIS) map was created that reflected current land use in the city. Data were compiled using 2m resolution Digital Ortho Quarter Quads. Using this backdrop, land use zones were digitized on-screen. Wooded (13%), Agricultural (20%), and Open Areas (14%) land use types accounted for nearly half the city's land area and represent a conservative estimate of …

Linking Transport Infrastructure Investments And Economic Development In Sub-Saharan Africa, Ambe J. Njoh

School of Geosciences Faculty and Staff Publications

The study explores the link between investments in transportation infrastructure, operationalized in terms of road density, and economic development, defined in terms of gross domestic product per capita (GDP/Cap), in sub-Saharan Africa (SSA). The findings support the hypothesis of a positive association between the two variables. The association is stronger for paved, than for all, roads in general. Furthermore, a negative but statistically insignificant relationship is observed between unpaved roads and economic development. Thus, economic development is a function more of quality, than quantity of roads in SSA. Therefore, a more judicious use of the scarce resource of sub-Saharan African …

Effects Of Spatial Resolution And Landscape Structure On Land Cover Characterization, Wenli Yang

Department of Geography: Dissertations, Theses, and Student Research

This dissertation addressed problems in scaling, problems that are among the main challenges in remote sensing. The principal objective of the research was to investigate the effects of changing spatial scale on the representation of land cover. A second objective was to determine the relationship between such effects, characteristics of landscape structure and scaling procedures. Four research issues related to spatial scaling were examined. They included: 1) the upscaling of Normalized Difference Vegetation Index (NDVI); 2) the effects of spatial scale on indices of landscape structure; 3) the representation of land cover databases at different spatial scales; and 4) the …

RISK: Health, Safety & Environment (1990-2002)

The authors show that in the 1940's technical consensus began to develop about the effects of land-based waste disposal on groundwater degradation. They go on to explain why this understanding was only slowly reflected in federal legislation.

The Effects Of Hydrilla Infestation On Selected Wintering Waterfowl: Santee Copper Lake System, South Carolina, William Davis

Masters Theses & Specialist Projects

Hydrilla is an exotic aquatic weed that was introduced into Florida in the 1950's. Since that time it has spread rapidly from lake to lake throughout the southeast and beyond. The Santee Cooper lake system in eastern South Carolina was infested with the weed in the early 1980's. Since that time lake managers have sought ways to eliminate the aquatic plant and have succeeded to a great extent through the use of sterile grass carp as a biological control agent. This paper, however, contains evidence to support the view that hydrilla is actually a beneficial habitat for many species on …

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard

Masters Theses & Specialist Projects

The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …

Evaluation Of Selected Atmospheric Indices For The Prediction Of Thunderstorms At Omaha, Nebraska, Fred Ladehoff

Open Access Master's Theses (through 2010)

This study examines the values of five stability indices (the Showalter Index, the K Index, the Vertical Totals Index, the Cross Totals Index, and the Total Totals Index) for Omaha, Nebraska during the months of March through September, 1964 through 1973. Index means during thunderstorm periods and non-thunderstorm periods should show a distinct difference. Even though indices can be an important tool, it must be accentuated that indices should never be used as the sole factor in the prediction of thunderstorm or non-thunderstorm occurrences. This study shows that even at the highest skill scores, many mistakes would be made in …

Quaternary Bear River Paleohydrogeography Reconstructed From The 87sr/86sr Composition Of Lacustrine Fossils, David P. Bouchard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diverted from its former course to the Pacific Ocean by basalt flows in Gem Valley, Idaho, the Bear River presently flows south into the Bonneville Basin. Constraining the timing of the river's diversion is pivotal to understanding the hydrologic budgets, and thus the climatological implications of the Bonneville Basin lakes. This study employs strontium (Sr) isotopes in mollusc fossils as a tracer of the Bear River water that entered Lake Thatcher, a small, closed-basin lake into which the redirected river flowed en route to the Bonneville Basin. The Sr ratios, combined with the temporal control afforded by amino acid geochronology …

Geomorphology Of The Green River In Dinosaur National Monument, Paul E. Grams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Longitudinal profile, channel cross-section geometry, and depositional patterns of the Green River in its course through the eastern Uinta Mountains are each strongly influenced by river-level geology and tributary sediment delivery processes. We surveyed channel cross sections at 1-km intervals, mapped surficial geology, and measured size and characteristics of bed material in order to evaluate the geomorphic organization of the 70- km study reach. Canyon reaches that are of high gradient and narrow channel geometry are associated with the most resistant lithologies exposed at river level and the most frequent occurrences of tributary debris fans. Meandering reaches that are characterized …

Modelling Vegetation Cover Types Using Multiseasonal Remotely Sensed Data To Compare Ecotones At Multiple Spatial And Spectral Resolutions, Kimberly Patraw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Army National Guard Bureau has implemented a cooperative project with Utah State University to help with the use, display, and evaluation of environmental data for maintaining land condition. Camp Grayling, Michigan, is comprised of deciduous and evergreen forest types. Use of remote sensing for classification has been limited in this region due to the difficulty of species-level classification using single-date remote-sensing techniques. Also, remote sensing has traditionally focused on mapping homogenous zones rather than vegetation boundaries, while one of the concerns for land managers is the nature of vegetation edges (ecotones).

This study analyzed each season and band from …

Impacts Of Air Temperature Variations On The Boro Rice Phenology In Bangladesh: Implications For Irrigation Requirements, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Air temperature significantly affects crop phenology. Numerous experiments have shown that prevailing air temperature determines the length of crop growth stages. Irrigation field requirements depend on the length of the crop growth stages. In the present study, a physically based parametric model, YIELD, has been applied to estimate the impacts of fluctuating air temperature (due to inter-annual climatic variability and global warming) on evapotranspiration water requirements and the length of growth stages of the irrigated boro rice in Bangladesh. The YIELD model is crop specific and crop-growth-stage specific which is a compromise between area-specific regression models and complex crop growth …
