High order stochastic transport and Lagrangian data assimilation
Ocean currents transport a variety of natural (e.g. water masses, phytoplankton, zooplankton, sediments, etc.) and man-made materials (e.g. pollutants, floating debris, particulate matter, etc.). Understanding such uncertain Lagrangian transport is imperative for reducing environmental damage due …

Continuous and discrete time stochastic transport: mathematical models of fractional transport on networks and in a continuum
Analysing and predicting dynamics of stochastic transport systems is paramount in fields including chemistry, physics and finance. A major component of these systems is diffusion; a transport process whereby particles move from a region of high concentration to a region of low concentration. …

A Potential Flow Model of a Fire Sprinkler Head
… of an instability model coupled with a stochastic transport model can paint most of the sprinkler spray picture, but requires input in the form of the thickness and velocity of unstable fluid sheets. The model outlined forgoes traditional CFD to solve for water jet-deflector …

Development and analysis of high order neutron transport-depletion coupling algorithms
The coupling of depletion and neutron transport together creates a particularly challenging mathematical problem. Due to the stiffness of the ODE, special algorithms needed to be developed to minimize the number of transport simulations required. In addition, for stochastic transport, both the time …

Eigenfunction expansion of the time and space-dependent 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 for problems demanding higher accuracy than such simplified models afford. In …

Modeling and simulation of stochastic phenomena in carbon nanotube-based single molecule sensors
… and limits to integrating data from many noisy stochastic sensors, show how these sensors can be used to monitor nitric oxide inside cells with unprecedented spatiotemporal resolution, and describes what is needed to engineer a selective adsorbed phase. In addition, another method of stochastic …

Feasibility of breeding in hard spectrum boiling water reactors with oxide and nitride fuels
… model was developed for the RBWR using the stochastic transport code MCNP. The code was coupled with a lumped channel thermalhydraulics 5-channel model for steady-state analyses. The depletion code MCODE, which links MCNP with ORIGEN, was used for all burnup calculations. Select physics …

Biomolecular transport at and through two-dimensional materials
… applications of nanopores for sequencing is the stochastic transport of DNA through the nanopore contributing to noise in the readout. Experiments have tested DNA transport though graphene nanopores however the strong hydrophobic interactions between DNA and graphene limit DNA capture and …

Investigation of a stochastic solute transport model and development of inverse methods in hydrogeology
This thesis encompasses two aspects of stochastic solute transport modelling in porous media. One part is dedicated to investigating a stochastic transport model. In the second part, two types of inverse methods are developed to solve the inverse problem in stochastic contaminant transport …
