Optimizing Monte Carlo simulation of the square-well fluid

Creator:: Perlin, Michael A.
Abstract:: We identify and develop efficient Monte Carlo methods for determining thermodynamic properties of the square-well fluid in order to test square-well density functional theories near the critical point. Previous works have developed generic so-called histogram methods for collecting statistics on low energy system states, but little or no literature exists...

Freezing a Softly Repulsive Fluid : Monte Carlo Methods and the Weeks-Chandler-Andersen Potential

Creator:: May, Christopher
Abstract:: The equation of state for a fluid described by the Weeks-Chandler-Andersen (WCA) potential was solved to determine at what pressures and temperatures the fluid will theoretically freeze. A Monte Carlo (MC) algorithm was used to sample a system of 256 spheres for a set of thermodynamic averages to locate and...

Ensemble Monte-Carlo planning : an empirical study

Creator:: Lewis, Paul
Abstract:: Monte-Carlo planning algorithms such as UCT make decisions at each step by intelligently expanding a single search tree given the available time and then selecting the best root action. Recent work has provided evidence that it can be advantageous to instead construct an ensemble of search trees and make a...

Diffusion Accelerated Implicit Monte Carlo via Nonlinear Elimination for Thermal Radiative Transfer

Creator:: Lam, Adam Q.
Abstract:: In this dissertation, we derive and implement a new transport-diffusion hybrid algorithm for solving thermal radiative transfer (TRT) problems. Using the method of nonlinear elimination (NLEM), the TRT system of equations can be written in terms of a transport equation with the absence of scattering and a diffusion equation. The...

Determining free energies of hard sphere fluids via Monte Carlo simulation

Creator:: Valeskea, Austin
Abstract:: Free energy is a fundamental property of a thermodynamic system, from which pressure, entropy, and other interesting properties can be derived. It is useful, then, to be able to accurately compute the free energy at various densities and temperatures in a way that can serve as the basis for further...

Monte Carlo Simulations of Structure and Melting Transition of Small Ag Clusters

Creator:: Collins, Lee
Abstract:: The behavior of small atomics cluster largely depends on their geometry, due to the high ratio of surface atoms to interior atoms. One interesting aspect to study clusters centers around characterizing the transition behavior between nite and bulk materials, where the ratio of surface atoms to interior atoms is very...

Adaptive sampling of spatial point processes

Creator:: Thompson, Steven Kirk
Abstract:: Adaptive sampling designs are those in which observations made during a survey may be taken into account when selecting the sites for further observations. Increases in survey precision may be achieved through adaptive procedures. The most efficient designs incorporate flexible sample size along with sequential selection of sites. In surveys...

Development of an accurate Monte Carlo treatment plan calculation framework for the purpose of developing dose calculation error predictors for a widely implemented clinical algorithm

Creator:: Egan, Alexander J.
Abstract:: Monte Carlo (MC) algorithms are widely accepted as the most accurate method to calculate dose in a patient geometry. For this work the EGSnrc MC code was used as a benchmark for the identification of dose calculation errors produced by the widely implemented analytical anisotropic algorithm (AAA). By correlating the...

Extending the applicability of implicit Monte Carlo Diffusion : frequency dependence and variance reduction using the difference formulation

Creator:: Cleveland, Mathew A.
Abstract:: The intent of this work is to extend Implicit Monte Carlo Diffusion (IMD)[Gen. 2001] to account for frequency dependence and to incorporate the difference formulation[Szo. 2005] as a source manipulation variance reduction technique. This work shows the derivation of the probabilities and the associated proofs which govern the frequency dependent...
