Identifying metabolic indicators of phytoplankton and comparing the temporal changes in algal community composition in two Lake Ontario areas of concern
(2021-12-01)
Freshwater algal blooms transition into harmful algal blooms (HABs) when cyanobacteria produce toxins that impact ecosystem health. The point at which algal blooms transition into HABs is not fully understood, but I believe ...
Conductive Si doped metal oxide fuel cell catalyst supports: understanding the role of Si content
(2021-08-01)
Current proton exchange membrane fuel cell (PEMFC) catalysts commonly use platinum supported on carbon (Pt/C) which is susceptible to corrosion, thus a highly conductive and stable Ti3O5 doped by Si (TOS) conductive metal ...
The synthesis and in vitro evaluation of short interfering RNA containing triazole functionalized sphingolipid-based derivatives
(2021-12-01)
RNA Interference (RNAi) is a natural cellular process that silences the expression of a target gene in a sequence-specific manner by mediating targeted mRNA degradation. One of the main challenges in RNAi research is ...
Video game livestream spectator: motivations and behaviours
(2021-12-01)
In recent years, video game livestreams have seen tremendous growth, resulting gaps of knowledge regarding studies on the motivations and behaviours of livestream spectators. This thesis presents two studies that intend ...
Refining adverse outcome pathways using Japanese Medaka Embryos (Oryzias latipes) exposed to 2,3,7,8-Tetrachlorodibenzodioxin
(2021-08-01)
Adverse outcome pathways (AOPs) are a framework that categorizes the impact of chemicals biologically from the initial molecular interaction through to the ecosystem level. This research aims to refine two existing AOPs ...
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 ...
Automatic knobs-tuning for DB2 using deep reinforcement learning
(2021-12-01)
Modern database management systems have hundreds of different configuration parameters (knobs) that control various aspects of how they behave and perform. These knobs must be properly tuned in order to maximize the ...
Extending the relational model with constraint satisfaction
(2021-01-01)
We propose a new approach to data driven constraint programming. By extending the relational model to handle constraints and variables as first class citizens, we are able to express first order logic SAT problems using ...
SegmentPerturb: effective black-box hidden voice attack on commercial ASR systems via selective deletion
(2021-08-01)
Voice control systems continue becoming more pervasive as they are deployed in mobile phones, smart home devices, automobiles, etc. Commonly, voice control systems have high privileges on the device, such as making a call ...
Empirically detecting colour: can we use solar cells as colour sensors?
(2021-08-01)
The purpose of this thesis was to explore the possibility of using solar cells as a colour sensor. Colour sensors already exist, yet they are either costly or fail at correctly sensing monochromatic light. Our experiment ...
