Benchmark criticality calculations for one speed neutron transport
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Benchmark criticality calculations for the two canonical problems of a critical slab and a sphere with isotropic scattering have been carried out using ... -
Chapman-Enskog solutions to arbitrary order in Sonine polynomials
(University of Missouri--Columbia, 2008)The Chapman-Enskog solutions of the Boltzmann equations provide a basis for the computation of important transport coefficients for simple gases and gas mixtures. These coefficients include the viscosity, the thermal ... -
Comparison and development of hurricane electrical power system damage models
(University of Missouri--Columbia, 2008)This document summarizes work done at Los Alamos national lab on Hurricane damage prediction, specifically, to the electrical power grid. An older, heuristic model is compared with a new automated heuristic method and a ... -
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 ... -
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 ... -
DSMC multicomponent aerosol dynamics : sampling algorithms and aerosol processes
(University of Missouri--Columbia, 2007)The focus of this research is on the use of the Direct Simulation Monte Carlo (DSMC) technique to elucidate the role of various phenomena that influence the evolution of nuclear aerosols. Several sampling algorithms and ... -
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 ... -
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 ... -
Modeling of molecular and particulate transport in dry spent nuclear fuel canisters
(University of Missouri--Columbia, 2007)There are two important phenomena associated with the depressurization of a dry spent nuclear fuel canister after the formation of a through-wall pinhole breach. The first phenomenon is the release from the canister of any ... -
Multiple potential well structure in inertial electrostatic confinement devices
(University of Missouri--Columbia, 2004)Inertial Electrostatic Confinement (IEC) devices are of interest as neutron generators for many applications. An essential part of these devices is the formation of a multiple potential well structure within the devices. ... -
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 ... -
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 ... -
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 ... -
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 ...
