Task-based image quality assessment in radiation therapy
(University of Missouri--Columbia, 2016)
Medical imaging is an integral part of radiation therapy, therefore image quality assessment (IQA) is important for improving patient treatments. Current IQA methods for radiation therapy do not directly consider the task ...
Transport of helium and fission product gases in porous/fractured geometry
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Measuring and quantifying the transport of helium and fission products in reactor materials is a critical element in the future success of Very High ...
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 ...
Numerical solutions to the Poisson equation in media surrounding multiple arbitrarily shaped bodies
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The dissertation describes a general, efficient, and parallelized approach to solving the Poisson equation in the volume surrounding multiple, arbitrarily ...
Generation, collection and characterization of nanoparticles and their diffusion in arbitrary tumor and normal tissue geometry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nanoparticles have unique electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of the bulk ...
Neutron exposure from electrom linear accelerators and a proton accelerator : measurements and simulations
(University of Missouri--Columbia, 2011)
The risk of developing radiation induced secondary cancers in patients undergoing external beam radiotherapy is a concern; particularly from secondary neutrons generated during delivery of high energy photon and proton ...
Uncertainty analysis of steady-state calorimetric emissivity measurements
(University of Missouri--Columbia, 2017)
Determining the accuracy and uncertainty in total hemispherical emissivity data is important in the uncertainty quantification of predictive models using radiant heat transfer. Very High Temperatures Reactors (VHTR) are ...
Measurement of coagulating silver and carbon aerosols using a tandem differential mobility analyzer
(University of Missouri--Columbia, 2013)
One of the unresolved technical issues associated with the high temperature gas-cooled reactor (HTGR) is the production of carbonaceous dust (e.g. by abrasion, corrosion, radiation damage, gas-to-particle conversion) and ...
Deposition of aerosols in cylindrical tubes and in human lung airways
(University of Missouri--Columbia, 2010)
Aerosol transport and deposition is of interest in many industrial and medical applications. This research is focused on two specific topics: deposition of aerosols in cylindrical tubes with emphasis on thermophoresis and ...
