Nanostructured carbon-based materials for electrochemical applications
(2019-12-01)Mesoporous carbons have been widely studied due to the relevance of these materials for applications in energy storage and conversion devices (batteries, supercapacitors, and fuel cells), mainly due to their high surface ... -
A negotiation protocol with conditional offers for camera handoffs.
(2014-10-01)This thesis explores the idea of conditional offers during camera handoff negotiations. In a departure from contract-net inspired negotiation models that have been proposed for camera handoffs, the current scheme assumes ... -
A new method of modelling tuneable lasers with functional composition
(2019-07-01)A new nonlinear model is proposed for tuneable lasers. Using the generalized nonlinear Schrodinger equation as a starting point, expressions for the transformations undergone by the pulse are derived for each of the five ... -
Non-precious metal catalysts prepared by chemical functionalization of carbon surfaces.
(2014-08-01)New sources of power are of great interest as attempts to make smaller, more convenient and environmentally friendly sources are being investigated. Hydrogen fuel cells are a way to combine both an effective method of power ... -
A nonlinear and nonlocal model for animal aggregation
(2022-09-01)An aggregation model is a kind of model used to show the dynamics of the distribution of the population of organisms. Mathematically, we can use a partial differential equation to model the density of an organism at different ... -
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 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) ... -
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 ... -
An optimization-based approach to image fusion using structural similarity
(2023-05-01)This thesis examines a framework for solving optimization problems involving structural similarity index measure Mean. Image fusion involves combining multiple images to preserve their most desirable characteristics. The ... -
Optimizing relational search with embedded neural network
(2023-04-01)Our research focuses on a novel method to query relational data. We propose the partial tuple search problem where a user can utilize keyword search to explore complex relational datasets. The challenge of evaluation of ... -
Palatable game development: lessons learned from Foodbot Factory, accessibility, and audio games
(2023-04-01)To address a lack of serious game work focusing on the development itself, this thesis describes recommendations for developers based on the development of Foodbot Factory, a nutrition-based serious game. Additionally, to ... -
A parallel adaptive method for pseudo-arclength continuation
(2011-08-01)We parallelize the pseudo-arclength continuation method for solving nonlinear systems of equations. Pseudo-arclength continuation is a predictor-corrector method where the correction step consists of solving a linear system ... -
Parsing genetic models
