[20100624] Development of sensitivity analysis with the use of TSUNAMI3D sensitivity coefficients for benchmark uncertainty analysis
The uncertainty of a critical benchmark experiment is a very important result. This value tells how well each parameter in the system is known and therefore how well the multiplication factor is known. The current method ... 
[20100624] Diagnostics of source distribution and particle population in Monte Carlo source iteration methods
This thesis is concerned with the development of meshinputfree diagnostics for the determination of the iteration at which the source distribution of a Monte Carlo simulation has reached a stationary state, as well as ... 
[20130130] Eigenfunction expansion of the time and spacedependent neutron survival probability equation
Owing to their inherent complexity, stochastic neutron transport problems are often examined by either using highly simplified models to make solutions more accessible, or at the cost of significant computational effort ... 
[20130130] A momentpreserving singleevent Monte Carlo model of electron and positron energyloss straggling
Analog simulation of energy straggling of electrons and positrons is computationally impractical because of longrange Coulomb forces resulting in highly peaked cross sections about small energylosses and extremely small ... 
[20100625] Nonlinear acceleration methods for evenparity neutron transport
Convergence acceleration methods for evenparity transport are being developed that have the potential to speed up transport calculations and provide a natural avenue for an implicitly coupled multiphysics code. An ... 
[20100903] Novel techniques for the detection and localization of attenuated gammaray sources
The use of cylindrical solidcrystal detectors for the detection and removal of gammaemitting sources has become a common practice for the cleanup of radiological contaminated sites. It is often difficult to determine ... 
[20100209] A prototype Compton imager : simulations, measurements and algorithm development
Compton imaging is a gamma ray imaging technique that has possible applications in the nuclear and medical industries. Compton imaging can localize the origin of a scattered gamma ray, to a cone, using a minimum of two ...
