Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of southern Oregon and northern California

Creator:: Zanger, Christopher
Abstract:: Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must be undertaken with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial framework for assessing, managing, and monitoring ecosystems that...

Automated web-based analysis and visualization of spatiotemporal data

Creator:: Keon, Dylan B.
Abstract:: Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

If you build it, will they come? Evolution towards the application of multi-dimensional GIS to fisheries-oceanography

Creator:: Vance, Tiffany C.
Abstract:: The development of new technologies in science is a balance between existence and use. There are three versions of this duality – something is built and users come, something is built and users don’t come, and, finally, potential users show up but the ballpark has not yet been built. In...

A recurrent neural network implementation using the graphics processing unit

Creator:: Moore, Christopher
Abstract:: We took the back-propagation algorithms of Werbos for recurrent and feed-forward neural networks and implemented them on machines with graphics processing units (GPU). The parallelism of these units gave our implementations a 10 to 100 fold increase in speed. For nets with less than 20 neurons the machine performed faster...

Of dragons, palaces, and gods : a mormon perspective on C. S. Lewis

Creator:: Garrett, Christopher Edward
Abstract:: During his lifetime C. S. Lewis chose to speak to Christians in plain and simple language that they could understand. Lewis taught and defended truths that he felt were discernible through reason. Morality, free will, and the divinity of Jesus Christ were fundamental to his core beliefs and teachings. His...

A novel landscape ecology approach for determining microhabitat correlations and faunal patchiness in extreme environments:pilot study for the Southern East Pacific Rise at 17-18° S

Creator:: Wargo Rub, Michelle
Abstract:: Since their discovery in 1977, hydrothermal vent communities have offered scientists a unique glimpse into a world that is supported primarily by chemically derived energy rather than direct energy from the sun. Furthermore, studies of hydrothermal vent ecosystems have introduced scientists to amazing animals that have successfully adapted to living...

Detection of actinides via nuclear isomer de-excitation

Creator:: Francy, Christopher J.
Abstract:: The detection of illicit weapons-grade nuclear material is a significant technical challenge receiving a great deal of attention in the nuclear community. A proposed solution is to actively bombard the material under investigation with neutrons, populating nuclear isomers in any potential fissile material. These isomers decay quickly, releasing gamma rays...

The implementation of two distributed databases of water-related information

Creator:: Ward, Brian S.
Abstract:: One of the most pressing concerns in the Geographic Information Science community is the distribution of spatial datasets over the Internet. Two projects of the Department of Geosciences at Oregon State University are in the process of distributing data. The Oregon Coast Geospatial Clearinghouse was implemented with the goal of...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...
