Improving the representation of large landforms in analytical relief shading

Creator:: Marston, Brooke E.
Abstract:: Relief shading is the most common type of cartographic relief representation for print and digital maps. Manual relief shading results in informative and visually pleasing representations of terrain, but it is time consuming and expensive to produce. Current analytical relief shading can be created quickly, but the resulting maps are...

Dynamic Probabilistic Risk Assessment Using ADAPT/RELAP5-3D for Cybersecurity Threat Analysis

Creator:: Wiltbank, Nathan E.
Abstract:: There is a growing need for an expanded Probabilistic Risk Assessment (PRA) framework that is able to accommodate new uncertainties that are present in Generation 3+ reactor designs. Dynamic PRA (DPRA) can allow for a more realistic risk assessment by taking advantage of established nuclear simulation codes to drive Dynamic...

Material Expressions of Class, Status and Authority amongst Commissioned Officers at Fort Yamhill and Fort Hoskins, Oregon, 1856-1866

Creator:: Eichelberger, Justin E.
Abstract:: During the 19th century the United States Army was a military institution characterized by a hierarchical system of authoritative, social and economic inequality between members of its different military grades. Although necessary for insuring military discipline within the Army this system of inequality also influenced the non-military social lives of...

Neutron Attenuation and Hydration of Cement Paste made with Light and Heavy Water

Creator:: Goodwin, Margaret N.
Abstract:: Neutron radiography has been used to study cementitious materials. This thesis studies the impact of heavy water on both the rate of hydration and neutron radiography. The neutron attenuation coefficients of light and heavy water were measured. Cement pastes were made with both heavy and light water. The attenuation coefficients...

Boredom, Buttons, and Booze: The Lifeways of an Enlisted Soldier Stationed at Fort Hoskins (35BE15), Oregon

Creator:: James, Shane P.
Abstract:: In 1976-77 and 2010, Oregon State University (OSU) excavated portions of the enlisted men’s barracks and privy at Fort Hoskins, a Civil War-era fort. In operation from 1856 to 1865, this fort served as part of a security network to protect and monitor the recently created Coast Indian Reservation. The...

Development of a Fundamental Depth-Dependent Neutron Dosimetry Model

Creator:: Anspach, Logan J.
Abstract:: Current neutron dosimetry methods rely on the assumption that charged particle equilibrium (CPE) is established within the tissue medium. This maintains that the kinetic energy transferred to the medium (KERMA) is equivalent to absorbed dose. However, this assumption is only valid for large volumes such as the whole body. For...

A Deterministic Photon and Electron Dosimetry Model for the Lens of the Eye

Creator:: Boozer, David L.
Abstract:: The lens dose equivalent (LDE) is a regulatory limit set to protect radiation workers. Current methods for estimating the LDE are specific to beam sources in a vacuum and require interpolating data from tables. A new set of deterministic equations for photon and electron point sources has been developed. These...

Comparing Random and Nonrandom Spatial Patterns of Artifacts within Lithostratigraphic Unit 3 at Cooper’s Ferry, Idaho

Creator:: Gregory, Alex R.
Abstract:: Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...

Diversity, Generalization, and Specialization in Plant-Pollinator Networks of Montane Meadows, Western Cascades, Oregon

Creator:: Helderop, Edward
Abstract:: Despite the importance of plant-pollinator interactions for ecological communities, few long-term observational studies have been conducted of plant-pollinator networks. Using four years of plant-pollinator interaction data from 18 meadows in the Willamette National Forest, Oregon, this thesis examined how meadow size, the amount of nearby meadow habitat, weather, degree days,...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....
