Groundwater and stormwater treatment at western wood preserving facilities : an analysis of current treatment methods

Creator:: Ragan, Anita M.
Abstract:: The Pacific Northwest is blessed with an abundance of precipitation. This rainfall, however, can have important consequences for industries that must process the resulting stormwater for proper discharge. This is particularly true of wood treatment facilities. Past management practices at wood preserving facilities located in the Western United States create...

Oscillators and phase locked loops for space radiation environments

Creator:: Vandepas, Martin
Abstract:: Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

Hygro-mechanical response of clear softwood specimens to compression under cyclic climate

Creator:: Guo, Ning
Abstract:: Hygro-mechanical effect is a general term applied to all phenomena that involves interaction between moisture content and mechanical characteristics of hygroscopic materials by analogy to thermo-mechanical effects. The hygromechanical effects include (but are not limited to) free shrinkage/swelling, effect of moisture on elastic modulus, strength, creep, failure mechanisms, and mechano...
Resource Type:: Masters Thesis
Full Text:: thanks should go to Dr. Fred Kamke, Dr. Jamie Kruzic and Dr. David Rogge for being my committee members

Durability Assessment of Wood Composites Using Fracture Mechanics

Creator:: Mirzaei, Babak
Abstract:: The advent of synthetic adhesives has transformed the structural applications of wood. However, a persistent issue in adhesively-bonded wood products has been moisture durability. When designing wood based composites, moisture durability will depend on both the wood phase and the adhesive phase. A key question, therefore, is how does one...

Determining fracture toughness by orthogonal cutting of polyethylene and wood-polyethylene composites

Creator:: Semrick, Kalin
Abstract:: The purpose of this thesis was to evaluate orthogonal cutting as a method to determine the fracture toughness of low and high density polyethylene and wood plastic composites. A test fixture was developed to capture normal and tangential cutting forces at variable depth and rake angle. A tool interface method...
Resource Type:: Masters Thesis

Analysis of the antineutrino rate during CANDU reactor startup

Creator:: Matthews, Christopher
Abstract:: Detection systems used to monitor reactor operations are of significant interest as tools for verification of operator declarations. Current reactor site safeguards are limited to visual inspections and intrusive monitoring systems. The recent development of antineutrino detectors may soon allow real-time monitoring from an unobtrusive location. Antineutrinos are produced through...

Thermal hydraulic and fuel performance analysis for innovative small light water reactor using VIPRE-01 and FRAPCON-3

Creator:: Mai, Anh T.
Abstract:: The Multi-Application Small Light Water Reactor (MASLWR) is a small natural circulation pressurized light water reactor design that was developed by Oregon State University (OSU) and Idaho National Engineering and Environmental Laboratory (INEEL) under the Nuclear Energy Research Initiative (NERI) program to address the growing demand for energy and electricity....
Resource Type:: Masters Thesis
Full Text:: with Dr. Wu on the MASLWR Test Facility. I would like to thank Dr. Leah Minc and Dr. Jamie Kruzic

Evaluating the effectiveness and efficiency of continuous improvement training

Creator:: Wiseman, Lindsay M.
Abstract:: Training is a key business process used to increase the skills and knowledge of employees in an effort to improve overall performance. Evaluation of the effectiveness and efficiency of training processes is necessary to ensure time, money, and resources are used to provide the most benefit possible. This investigation is...

Preliminary investigation of X-ray imaging for dose extraction of BANG® polymer gel in intensity modulated radiation therapy

Creator:: Sath, Chhipo
Abstract:: This study investigated gel dosimetry with X-ray CT imaging as a possible means for extracting dose information from a 3D gel dosimeter. Currently Optical CT and MRI are the popular means of dose extraction, but X-ray CT imaging has the advantage of being more convenient and cost effective. The dosimetric...

Scaling analysis for the pebble bed of the very high temperature gas-cooled reactor thermal hydraulic test facility

Creator:: Nelson, Benjamin L.
Abstract:: The Very High Temperature Reactor (VHTR) has two possible core configurations, a hexagonal prismatic and a pebble bed. It is essential that an experimental facility be built for the validation of computer codes for the safe operation of the VHTR. The scaling of the prismatic core configuration has been analyzed...
