Geoarchaeological research within five river miles of the Upper Klamath River Canyon : use of pedogenic properties to calculate alluvial terrace age

Creator:: Hescock, Sara
Abstract:: Soil is a valuable medium when investigating the past-- from understanding rates of development, landform evolution, to the construction of various predictive models. Landforms and sediments provide insight into depositional environments and soil morphology indicates pedogenic change within those landforms. The rate at which pedogenesis occurs has been quantitatively measured...

Paleoenvironmental Reconstruction of Late Pleistocene and Holocene Human Ecologies: A Case Study of Phytoliths from the Lower Salmon River Canyon, Idaho

Creator:: Knapp, Dante L.
Abstract:: Archaeological excavations of the Cooper's Ferry site in the Lower Salmon River Canyon, Idaho, have revealed a stratified record of cultural occupation, spanning the late Pleistocene and early Holocene periods. The purpose of this study was to contribute to the understanding of cultural adaptive strategies represented in the archaeological record...

High Order Finite Elements SN Transport in X-Y Geometry on Meshes with Curved Surfaces in the Thick Diffusion Limit

Creator:: Woods, Douglas N.
Abstract:: The high-order finite element S[subscript N] transport equations are solved on several test problems to investigate the behavior of the discretization method on meshes with curved edges in X-Y geometry. Simpler problems ensured the correct implementation of MFEM, the general fi nite element library employed. A convergence study using the...

SCALE 6 (TRITON) Simulations of Fission Product Gamma Line Emissions and their Comparison to Plutonium and Uranium Measurements

Creator:: Sanchez, Timothy J.
Abstract:: Thin foil samples of special nuclear materials (SNMs) were irradiated for 60s using a Mark TRIGA II reactor, and their associated gamma emissions were recorded with a count time of 60s following irradiation. A rapid pneumatic transfer system was used to irradiate the samples in front of beam port #4....

Soft Robotics in Radiation Environments : A Prospective Study of an Emerging Automated Technology for Existing Nuclear Applications

Creator:: Oshiro, Tyler T.
Abstract:: Traditional robots have a long history in nuclear-related work because their integration decreases risk to humans in dangerous environments. Soft robotics is one promising new branch of traditional robotics with proposed applications in industry, medicine, and society. Collaborators from the Robotics mLab at Oregon State University (OSU) are currently working...

Discrete Ordinates Radiation Transport using High-Order Finite Element Spatial Discretizations on Meshes with Curved Surfaces

Creator:: Woods, Douglas N.
Abstract:: We spatially discretize the Sn transport equation using the high-order (HO) discontinuous finite element method (DFEM) on HO meshes. Previous work provided a proof-of-concept for this spatial discretization method in X-Y geometry. Included in the present work, we derive a spatial discretization for the Sn transport equation in both X-Y...

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...

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...

Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

Developing Software Tools to Characterize Electrochemical Loss Scenarios via Gamma Detection for Various Measurement Points, Source Geometries, and Process Times

Creator:: Harris, Noah C.
Abstract:: Faithful modeling of the expected gamma signals inside an electrochemical facility at various key measurement points is important for understanding what detection limits are available for the next generation of safeguards technologies. Gamma Detector Response and Analysis Software (GADRAS) and the Separation Safeguards Performance Model (SSPM) were used to build...
