Optimization Of Check Dams Through The Application Of Advanced Technologies, Praveen Jha Dr

Praveen Jha Dr

Scientific planning for conserving water and while minimizing the financial resources requirement for its implementation could be done through application of advanced technological programs developed by the author. Three state-of-art geo-spatial programs - Multi-Algorithm Automation Program (MAAP), Water Analysis Program (WAP) and Check Dam Optimization Program (CDOP) - would be used. MAAP produces land use land cover (lulc) map primarily by undertaking Digital Image Processing (DIP) of satellite data in an automated fashion using Artificial Intelligence (AI). WAP, a hydrology modeling program, would be used to generate information related to watershed, water flow, water accumulation etc. CDOP, coupled with MAAP …

Generating Contour Maps For Dynamic Fields Monitored By Sensor Networks, Cheng Zhong

Electronic Theses and Dissertations

Wireless sensor networks provide a new tool that enables researchers and scientists to efficiently monitor dynamic fields. In order to extend the lifetime of the network, it is important for us to minimize network data transmission as much as possible. Previous work proposed many useful aggregation techniques to answer max, min and average questions, and some of them have been employed in real applications. But we cannot get spatial information from these aggregation techniques. This thesis presents an efficient aggregation technique for continuous generation of contour maps for a dynamic field monitored by a wireless sensor network. A contour map …

A New Application Of Spatiotemporal Analysis For Detecting Demographic Variations In Aids Mortality: An Example From Florida, Yuwen Chiu, Chiehwen Ed Hsu

Chiehwen Ed Hsu

The purpose of the present study was to characterize, geographically and temporally, the patterns of acquired immune deficiency syndrome (AIDS) death disparity in 67 Florida jurisdictions, and to determine if the detected trends varied according to age, race, and sex. The space-time scan statistic proposed by Kulldorff et al was used to examine the excess AIDS deaths that occurred between 1987 and 2004. Results were geographically referenced in maps using EpiInfo and EpiMap made available by the Centers for Disease Control. Miami-Dade and the nearby counties including Broward, Martin, and Palm Beach are the most likely clusters (observed/expected: 1505.16) with …

Finding A "Disappearing" Nontimber Forest Resource: Using Grounded Visualization To Explore Urbanization Impacts On Sweetgrass Basketmaking In Greater Mt. Pleasant, South Carolina, Patrick T. Hurley, Angela C. Halfacre, Norm S. Levine, Marianne K. Burke

Environment and Sustainability Faculty Publications

Despite growing interest in urbanization and its social and ecological impacts on formerly rural areas, empirical research remains limited. Extant studies largely focus either on issues of social exclusion and enclosure or ecological change. This article uses the case of sweetgrass basketmaking in Mt. Pleasant, South Carolina, to explore the implications of urbanization, including gentrification, for the distribution and accessibility of sweetgrass, an economically important nontimber forest product (NTFP) for historically African American communities, in this rapidly growing area. We explore the usefulness of grounded visualization for research efforts that are examining the existence of "fringe ecologies" associated with NTFP. …

Gasoline Costs, Public Transit, And Sustainability, Bradley W. Lane

Bradley W. Lane

Excessive levels of automobile driving are generally acknowledged to have several negative externalities that contribute to the lack of sustainability in current transport systems. Achieving a reduction in VMT inevitably requires the introduction of disincentives for driving. This has generally been lacking in the US, which has relatively low parking costs and taxes on fuel compared to its developed-world counterparts. However, starting immediately after the Hurricane Katrina disaster, fuel costs in the United States have increased dramatically relative to previous long-term price behavior. This increase has brought attention to the driving behavior and travel preferences of US citizens. A large …

Comparing Pixel- And Object-Based Classification Methods For Determining Land-Cover In The Gee Creek Watershed, Washington, Tyler Vick

Geography Masters Research Papers

This study analyzes land-cover types in the Gee Creek Watershed of southern Washington using the pixel-based and object-based image analysis approaches. Landsat imagery has traditionally been used for pixel-based classification and change detection in land-cover studies. In recent years, the availability of high-resolution satellite and aerial imagery have enabled for land-cover classification to occur at scales not possible using traditional Landsat imagery. High-resolution aerial imagery of 1 meter or greater has become readily available for free. Yet, commonly found black and white (or panchromatic) aerial imagery is without the multiple spectrum bands found in Landsat imagery, thereby limiting the accuracy …

"Sustainable Development": Critical Concepts In Geography, Tyler Vick

Geography Masters Research Papers

This paper reviews significant geographic contributions to academic literature in the arenas of conservation, environmental thought, and "sustainable development", in order to understand why geographers have not been more central contributors to the sustainable development movement. A review of geographic literature reveals no lack of understanding on the "sustainable development" concept. However, the disciplines' contributions are lacking in numbers relative to published articles and in developing research and practical methods for directly benefiting the "sustainable development" movement. In fact, only a handful of geographers have made multiple literary contributions on the topic of "sustainable development."

The discipline of geography is …

Automated Vector-To-Raster Image Registration, Boris Kovalerchuk, Peter Doucette, Gamal Seedahmed, Robert Brigantic, Michael Kovalerchuk, Brian Graff

Computer Science Faculty Scholarship

The variability of panchromatic and multispectral images, vector data (maps) and DEM models is growing. Accordingly, the requests and challenges are growing to correlate, match, co-register, and fuse them. Data to be integrated may have inaccurate and contradictory geo-references or not have them at all. Alignment of vector (feature) and raster (image) geospatial data is a difficult and time-consuming process when transformational relationships between the two are nonlinear. The robust solutions and commercial software products that address current challenges do not yet exist. In the proposed approach for Vector-to-Raster Registration (VRR) the candidate features are auto-extracted from imagery, vectorized, and …

Four-Thousand-Year-Old Gold Artifacts From The Lake Titicaca Basin, Southern Peru, Mark Aldenderfer, Nathan M. Craig, Robert J. Speakman, Rachel Popelka-Filcoff

Nathan M Craig

Artifacts of cold-hammered native gold have been discovered in a secure and undisturbed Terminal Archaic burial context at Jiskairumoko, a multicomponent Late Archaic–Early Formative period site in the southwestern Lake Titicaca basin, Peru. The burial dates to 3776 to 3690 carbon-14 years before the present (2155 to 1936 calendar years B.C.), making this the earliest worked gold recovered to date not only from the Andes, but from the Americas as well. This discovery lends support to the hypothesis that the earliest metalworking in the Andes was experimentation with native gold. The presence of gold in a society of low-level food …
