Modelling calcite dissolution in a rotating disc reaction vessel
(2021-06-01)
The carbonate system is ubiquitous in nature, playing a role in many natural and industrial processes. For calcite dissolution, the kinetics and mass transport of the dissolved species reflect both the chemistry of the ...
Determining the effects of harmful algae blooms and their toxins on fish from both environment and laboratory-based studies through the use of proteomics
(2021-01-01)
The effects of harmful algae blooms (HABs) on wild, freshwater, large-bodied fish have been under examined. Blood samples were collected from fish in Hamilton Harbor and Lake Erie to assess the effects of HABs on a molecular ...
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 ...
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 ...
Assessing the memorability of familiar vocabulary for system assigned passphrases
(2021-08-01)
Text-based secrets are still the most commonly used authentication mechanism in information systems. Initially introduced as more secure authentication keys that people could recall, passphrases are tokens consisting of ...
Group representation learning for group recommendation
(2021-01-01)
Group recommender systems facilitate group decision making for a set of individuals (e.g., a group of friends, a team, a corporation, etc.). Existing group recommendation methods mostly learn group members' individual ...
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 ...
Approaching Humanities Questions Using Slow Visual Search Interfaces
(2021-06-01)
In this paper we discuss a visual search system that was designed and implemented for humanities scholars to ask questions of large document corpora. The system allows searches to be specified through traditional search, ...
Visualization, Digital Humanities, and the Problem of Instrumentalism
(2021-06-01)
In this paper we present the concept of “slow analytics” that attempts to ridge the gap between humanities tasks and visualization. Often within Technological disciplines the pursuit of speed and efficiency are paramount. ...
A Vision-Based System For Non-Intrusive Posture Correction Notifications
(2021-05-20)
Sedentary lifestyle and the prolonged sitting associated with it may have negative health consequences and poor sitting posture only exacerbates that. In this thesis I propose a software application for monitoring a computer ...
