Investigation of portable nuclear power systems
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Energy needs for modern society are an ever-changing and complex problem. One of the most diverse areas of energy needs is portable energy generation. ...
The effect of uncertainty in "field of the day" treatment regimes in proton therapy
(University of Missouri--Columbia, 2015)
Purpose: A common practice in proton therapy is to plan a treatment using multiple fields, but only deliver a subset of those fields for each fraction. This practice could lead to increased uncertainty in the treatment. ...
Validation of radiation treatment planning with a pseudo-CT derived from MR images
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Historically CT has been the necessary for radiation therapy dose calculation due to its inherent density information. However there is increased ...
Robust and efficient process for acceptance testing of radiation therapy machines
(University of Missouri--Columbia, 2015)
The current (legacy) paradigm for acceptance testing (AT), commissioning, and ongoing quality assurance (QA) and quality control (QC) of linac and treatment planning systems (TPS) is extremely inefficient requiring substantial ...
Solutions of some transport problems in molecular and phonon transport
(University of Missouri--Columbia, 2012)
Nuclear reactor fuel undergoes vast changes during its lifetime. The fuel generates heat energy while simultaneously suffering neutron bombardments and swelling/rupture due to fission product/gas migration, aggregation and ...
Direct simulation Monte Carlo study of phonon heat conduction in solid nuclear fuels
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Heat transfer in solid nonmetallic thin films can be best described by the phonon Boltzmann transport equation (BTE). In this study, the direct simulation ...
Process management and scheduing [sic] in radiation therapy
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Management of complex, advanced technology, high cost, and high risk operations requires reliance on systems engineering principles. This approach has ...
Preparation of quantum fingerprint-ready metal-gallium arsenide interfaces for molecular characterization
(University of Missouri--Columbia, 2014)
Quantum Fingerprint� (Charge Based Transient Level Spectroscopy Analysis) trace chemical detectors are desirable due to their high sensitivity, high selectivity, rapid acquisition and response rates, and robustness. These ...
Photon intermediate direct energy conversion using a Sr-90 beta source
(University of Missouri--Columbia, 2012)
This thesis covers an examination of a need for a compact, long lived power source and a proof of concept for one such design. To begin, tests were done dealing with photovoltaics and their lifetime while undergoing radiation ...
Modeling and analysis of a portable, solid-state neutron detection system for spectroscopic applications
(University of Missouri--Columbia, 2012)
This paper discusses a new neutron detection system that allows local volumetric identification of fast neutron thermalization in the context of forming a solid state Bonner-like neutron spectrometer. The resulting departure ...
Modification of materials for high oxidation resistance
(University of Missouri--Columbia, 2012)
As a result of high oil prices and the increase effects of greenhouse gases due to the combustion of fossil fuels is necessary to find other sources of energy. Hydrogen has the potential to replace part of the fossil fuel ...
Large-Area Single-Crystal Diamond Films Via Hot Filament Chemical Vapor Deposition
(University of Missouri--Columbia, 2014)
Ultra-fast magnetic resonance imaging for small animal models
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Magnetic Resonance Imaging (MRI) has been widely used in clinical diagnoses since 1980s. The scan speed of MRI is crucial based on several reasons. ...
Dosimetric properties and radiation hardness of the storage phosphor europium doped potassium chloride for radiation therapy dosimetry
(University of Missouri--Columbia, 2011)
Multidimensional reusable dosimeters are extremely important for characterizing the complex dose distributions associated with modern radiation therapy techniques, such as intensity modulated radiation therapy (IMRT). In ...
Numerical solutions of Reeks-Hall equation for particulate concentration in recirculating turbulent fluid flow
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Source term is an important issue in safety assessment of nuclear power plants. Therefore, modeling of particulate concentration in reactor coolant ...
