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 ... -
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
(2022-01-01)Applications of computer vision have seen great success recently, yet there are few approaches dealing with visual illustrations. We propose a collection of computer vision applications for parsing genetic models. Genetic ... -
Peer evaluation with graph neural networks
(2021-12-01)Peer assessment systems are rising in various social contexts, such as peer grading in large (online) classrooms, peer review in conferences, peer art evaluation, etc. However, peer assessments might not be as accurate as ... -
Perceptual Biases in Font Size as a Data Encoding
(IEEE, 2017-07-04)Many visualizations, including word clouds, cartographic labels, and word trees, encode data within the sizes of fonts. While font size can be an intuitive dimension for the viewer, using it as an encoding can introduce ... -
Performance assessment of Au SERS substrates prepared by deposition of Au nanoparticles on screen-printed SiO2 particle films
