Novel electrode materials and advanced electrochemical diagnostics for electrochromic devices
(2022-04-01)Electrochromic materials (ECMs) are a class of “smart” materials used in a variety of applications due to the ability to alter their optical properties with the application of a potential. For these applications, ECMs are ... -
A novel method of generating Dendritic cells in vitro using the KG-1 cell line and its use as a model for testing effects of lactic acid bacteria
(2011-08-01)Dendritic cells (DCs) are prime mediators of innate and adaptive immunity. In humans the DC population comprise only 0.1% of all leukocytes, making their isolation and ex vivo manipulation difficult. Since study of DC ... -
Numerical methods for simulating diffusion in cellular media
(2011-12-01)Diffusion imaging is a relatively recent branch of magnetic resonance imaging that produces images of human physiology through diffusion of water molecules within the body. One difficulty in calculating diffusion ... -
A numerical study of the effects of inhomogeneous media in diffusion weighted imaging
(2015-07-01)Diffusion Weighted Imaging (DWI) -a common Magnetic Resonance Imaging (MRI) technique - is used to infer material properties of tissues from the average diffusion of water molecules over brief time intervals. In particular, ... -
Object-centric temporal navigation for dynamic information visualizations.
(2014-08-01)We introduce object-centric temporal navigation for time-varying information visualizations. In our approach, navigation through time is controlled by interacting directly with any data item, enabling simultaneous exploration ... -
On deep learning in physics
(2021-04-01)Machine learning, and most notably deep neural networks, have seen unprecedented success in recent years due to their ability to learn complex nonlinear mappings by ingesting large amounts of data through the process of ... -
On matrix-free pseudo-arclength continuation methods applied to a nonlocal partial differential equation in 1+1D with pseudo-spectral time-stepping
(2013-08-01)In this thesis we examine a recent animal aggregation model which describes the evolution of two populations of animals moving on a 1-dimensional spatial domain differing only by the direction they travel. The equations ... -
On the integration of Computational Fluid Dynamics (CFD) simulations with Monte Carlo (MC) radiation transport analysis
(2009-12-01)Numerous scenarios exist whereby radioactive particulates are transported between spatially separated points of interest. An example of this phenomenon is, in the aftermath of a Radiological Dispersal Device (RDD) ... -
On the potential of intent-based access control (IBAC) in preventing insider threats
(2015-11-01)Existing access control mechanisms are based on the concepts of identity enrollment and recognition, and assume that recognized identity is synonymous with ethical actions. However, statistics over the years show that the ... -
An Online System for Visualizing UOIT Class Schedules
(2021-06-02)The objective of this thesis is to design a system that will enable users to visualize aspects of a schedule so that the information can be interpreted in a meaningful way. The concept of visualizing data has allowed many ... -
Opportunities for the deep neural network method of solving partial differential equations in the computational study of biomolecules driven through periodic geometries
(2022-08-01)As deep learning emerged in the 2010s to become a groundbreaking technology in machine vision and natural language processing, it also ushered in many new algorithms for use in scientific research. Among these is the neural ... -
Optimization algorithms in compressive sensing (CS) sparse magnetic resonance imaging (MRI)
(2010-06-01)Magnetic Resonance Imaging (MRI) is an essential instrument in clinical diag- nosis; however, it is burdened by a slow data acquisition process due to physical limitations. Compressive Sensing (CS) is a recently developed ... -
