Towards deep learning models for automatic computer program grading
(2023-04-01)Automatic grading of computer programs has a great impact on both computer science education and the software industry as it saves human evaluators a tremendous amount of time required for assessing programs. However, to ... -
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 low dose retrospective dosimetry on shelled species
(2020-08-01)This work investigates calcified tissues of shelled species for retrospective dosimetry using electron paramagnetic resonance (EPR) spectroscopy. To determine applicable samples for low dose studies, shells of crustacean ... -
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 sustainable machining of difficult-to-cut materials using nano-cutting fluids
(2018-05-01)Providing environmentally friendly conditions and optimizing energy consumption are two essential requirements in order to achieve sustainable machining processes. One of the major sustainable machining concerns is the ... -
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 ... -
Transactive energy control of electric energy storage to mitigate the impact of transportation electrification in distribution systems
(2016-11-01)The adoption of Plug-in electric vehicles (PEVs) as a substitute to gasoline-based internal combustion engine vehicles represent a major change in the transportation sector. Typically, PEVs uses electricity to charge the ... -
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 ... -
Transformative learning and critical thinking in asynchronous online discussions: a systematic review
(2017-11-06)Transformative learning is a fundamental component of the higher education experience. Transformative educational experiences are those in which students are engaged in sustained and critically reflective discourse that ... -
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 ... -
Transient heat transfer analysis of heat exchangers in a Marnoch Heat Engine
(2009-12-01)The Marnoch heat engine (MHE) is a new type of power generation device that is under research and development at the University of Ontario Institute of Technology. In this thesis, the transient heat transfer behaviour of ... -
Transmutation rates in the annulus gas of pressure tube water reactors
(2011-07-01)CANDU (CANada Deuterium Uranium) reactor utilizes Pressure Tube (PT) fuel channel design and heavy water as a coolant. Fuel channel annulus gas acts as an insulator to minimize heat losses from the coolant to the moderator. ... -
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 ... -
