Towards efficient and scalable computer vision systems
(2018-01-01)There is a large growth in hardware and software systems capable of producing vast amounts of image and video data. These systems are rich sources of continuous and possibly infinite image and video streams. This motivates ... -
Towards implicit learning of system-assigned authentication tokens
(2018-02-01)People tend to choose predictable passwords which are vulnerable to guessing attacks. To combat the security issue, system-assigned authentication keys were proposed, but coming at a cost to memorability. In this thesis, ... -
Towards improving the usability of system-assigned PINs: can implicit learning techniques help?
(2023-08-01)Personal Identification Numbers (PINs) are widely used for automated teller machines (ATMs), computers, mobile devices, debit cards, and credit cards. People tend to choose easy-to-recall PINs that are related to important ... -
Towards measuring privacy
(2015-04-01)The acceptable threshold for privacy is an individual choice, informed by culture, tradition and experience. That it is important, conversely, is self-evident. We use it to moderate personal information disclosure, how ... -
Towards molecular reconstruction in Coulomb explosion imaging
(2021-02-01)The interaction of a fast laser with molecules at the femtosecond time scale, leads to the latter losing most of its valence electrons and become positively charged. The molecule which was initially in an equilibrium state, ... -
Towards parallax-based unencumbered displays
(2015-01-01)We present an analysis of content adaptive parallax barriers used for multi-layer unencumbered displays. We explain the techniques involved in detail from the input light field to the output masks and how to display them. ... -
Towards secure and privacy preserving e-health data exchanges through consent based access control
(2017-09-01)How we administer healthcare continues to evolve alongside the advancement of information technology. As we become more connected, the Internet of Things and our want to share information in a timely manner encourage us ... -
Towards trusted and efficient temporal relational databases
(2018-12-01)This research is to develop a blockchain based database based on a relational database management system (RDBMS). The database guarantees authenticity of the stored records using immutable and verifiable signatures. The ... -
The toxicity of Harmony Landfill Leachate to Green Hydra (Hydra viridiisma)
(2010-08-01)Harmony Landfill is a former industrial waste disposal site located adjacent to Harmony Creek in Oshawa, Ontario, Canada. During active disposal, from 1957 until 1980, approximately 1 million tonnes of waste were land-filled ... -
The transcription factor, fixK, plays a central role in carbon source metabolism and cellulose synthesis in Komagataeibacter species
(2017-07-01)Komagataeibacter xylinus ATCC 53582 and K. hansenii ATCC 23769 are model bacterial cellulose producers. This thesis investigated both carbon source utilization and the role that a Crp/Fnr transcription factor, FixK, plays ... -
Transformer-based models for answer extraction in text-based question/answering
(2023-04-01)The success of transformer-based language models has led to a surge of research in various natural language processing tasks, among which extractive question-answering/answer span detection, has received considerable ... -
Transport-theory-equivalent diffusion coefficients for node-homogenized neutron diffusion problems in CANDU lattices
(2010-04-01)Calculation of the neutron flux in a nuclear reactor core is ideally performed by solving the neutron transport equation for a detailed-geometry model using several tens of energy groups. However, performing such detailed ... -
Trust-based framework for information sharing in health care
(2016-10-01)The use of information systems in the health care area specifically in Mobile health care, can result in delivering high quality and efficient patient care. At the same time, using electronic systems for sharing information ... -
Understanding and predicting method-level source code changes using commit history data
(2016-10-01)Software development and software maintenance require a large amount of source code changes to be made to a software repositories. Any change to a repository can introduce new resource needs which will cost more time and ... -
