Graduate Theses and Dissertations
Asteroids provide unique insights into the origin and early history of the solar system. Since asteroids are considered to be fairly pristine, studying them provides opportunities to learn more about the primordial solar system, its materials, processes and history. Since the discovery in 1801 of the first asteroid, Ceres, during the era when everyone was searching for the "missing planet", astronomers have been trying to understand what they are, where they came from, why they exist and what they can tell us about how our solar system formed and evolved.
Within the asteroid population are a number of sub-populations, the …
White River Forum Ii: Second Annual Meeting Of The White River Forum, John Havel, Kenneth Steele
White River Forum Ii: Second Annual Meeting Of The White River Forum, John Havel, Kenneth Steele
Technical Reports
This second annual meeting of the White River Forum is proof of widespread interest in the water quality of the Upper White River watershed. The participation of numerous elected officials, state and federal agencies, universities, businesses, and local citizens indicates that interest in understanding policy issues crosses political boundaries and occupations.
Wayne E. Sabbe Arkansas Soil Fertility Studies 2008, Nathan A. Slaton
Wayne E. Sabbe Arkansas Soil Fertility Studies 2008, Nathan A. Slaton
Arkansas Agricultural Experiment Station Research Series
Rapid technological changes in crop management and production require that the research efforts also be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts.

Development Of A Distributed Artificial Neural Network For Hydrologic Modeling, Rebecca Logsdon
Inquiry: The University of Arkansas Undergraduate Research Journal
Hydrological models are used to represent the rainfall-runoff and pollutant transport mechanisms within watersheds. Accurate representation of these dynamic and complex natural processes within a watershed is an important step in managing and protecting a watershed Artificial neural network (ANN) models are often used in hydrologic modeling. Typical ANN models are trained to use lumped data. However, watershed characteristics used as inputs in hydrological modeling are spatially and often temporally dynamic. Therefore, a lumped model does not have the ability to represent changes in spatial dynamics of a watershed. Therefore, the purpose of this study was to develop and test …
