Ab initio based Monte Carlo model of phase transformations in ferromagnetic shape memory alloys
… of a combination of ab-initio simulations and Monte Carlo models which allow an alloy to be examined across its phase space without the need for any empirical parameters. In this document, we focus on the Heusler alloy Ni50Mn50-XInX as it has already been the subject of substantial experimental …

Monte Carlo model of a low-energy neutron interrogation system for detecting fissile material
(cont.) Further MCNP simulations of the neutron source impinging on cargo containers suggest that this technique can respond, as expected, qualitatively differently to containers containing SNM from containers that do not. Containers that contain small amounts of fissile isotopes as in the case of …

A moment-preserving single-event Monte Carlo model of electron and positron energy-loss straggling
… spectra and dose profiles using single-event Monte Carlo methods would then require a large number of particle samples. In this thesis, we demonstrate that a pseudo-differential cross section designed to approximately yet accurately preserve energy-loss moments is capable of yielding accurate …

Building Inventory Simulations for High Velocity Garment Retail Stores
… portfolio complexity, this project created a Monte Carlo tool that simulates how upstream shipment decisions impact capacity utilization and product complexity. The simulation model was built in two steps, first a Monte Carlo model for aggregated store inventory, followed by machine learning …

Biosecurity and risk analysis for cow-calf enterprises: a simulation model for Bovine Viral Diarrhea Virus
A Monte Carlo model was developed to determine the cost-effectiveness of different biosecurity strategies for Bovine Viral Diarrhea Virus (BVDV) on cow-calf farms. Where possible, risk distributions were defined in the course of a critical literature review covering all publications since 1990 …

Monte Carlo Simulation of Silicon Devices Including Quantum Correction and Strain
The state of the art for full-band Monte Carlo device simulation is advanced on two fronts. First, quantum effects are taken into account by including quantum corrections in the semiclassical Monte Carlo framework. A quantitative study of corrections based on the Wigner transport equation and the …

Predicting Bitcoin: a robust model for predicting Bitcoin price directions based on network influencers
… of annualized gains. In this thesis, a model for predicting the future daily price of Bitcoin is proposed and evaluated in comparison to that of a purely random model. Bitcoin is a novel digital currency that relies on cryptography instead of a central authority to verify transactions. …

Monte Carlo Simulation of Nanostructures: Semiconductor Devices to Ion Channels
This dissertation discusses the transport Monte Carlo model and its application for simulation of semiconductor devices and biological ion channels. A quantum corrected 3-D Monte Carlo simulator has been developed to investigate the various physical phenomena underlying nanoscale semiconductor …

Modeling and simulation of The Transient Reactor Test Facility using modern neutron transport methods
… it also makes the reactor very challenging to model and simulate. In this thesis, we build a Monte Carlo model of TREAT's Minimum Critical Mass core to examine the effects of fuel impurities, calculate a reference solution, and analyze a number of multigroup cross section generation approaches. …

Optical reflectance spectroscopy for cancer diagnosis : analysis and modeling
… the development of algorithms for analyzing and modeling of the signals from optical spectroscopy. This dissertation is motivated by the detection of oral cancer, but some of the methods developed can be generalized to epithelial cancers of other sites. Two main topics are covered in this …

Diffusion in an absorbing porous medium : from microscopic geometry to macroscopic transport
Two physical models of diffusion in absorbing porous media are proposed on two length scales. One models diffusion in the pore space of a random medium with absorbing interfaces while the other is a reaction diffusion model where particles are absorbed in the bulk. Typical particle traveling …
