Data curation with ontology functional dependences
(2017-04-01)Poor data quality has become a pervasive issue due to the increasing complexity and size of modern datasets. Functional dependencies have been used in existing cleaning solutions to model syntactic equivalence. They are ... -
Deep learning approach to discontinuity-preserving image registration
(2020-05-01)Image registration is an indispensable tool in medical image analysis. Traditionally, registration algorithms are aimed at aligning image pairs using regularizers to impose smoothness restrictions on unknown deformation ... -
A deep learning approach to focal cortical dysplasia segmentation in children with medically intractable epilepsy
(2021-08-01)Paediatric epilepsy is one of the most common neurological disorders and has major impact on the cognition and quality of life of children. Focal Cortical Dysplasia (FCD) is one of the most common causes of medically ... -
Depletant induced attractions in red blood cells
(2018-10-01)Red blood cells suspended in plasma are able to aggregate into linearly stacked rouleau. The aggregations can form complex clusters and branching networks which cause complications in various pathological cases. The self ... -
Depletion induced bundling of rod-like colloids and simulations of triple helix bundles
(2023-06-01)We ran molecular dynamics simulations of rod-like colloids acting under depletion forces. In these simulations, we found bundling of the rods above a given strength of the depletion force. We then analyzed the bundle ... -
Design and evaluation of a novel convolutional neural network for short-term vehicle multi-traffic prediction
(2019-08-01)Short-term vehicle traffic forecasting is about predicting how traffic indicators are going to be in the near future. The main traffic parameters are: traffic volume, traffic speed, and congestion state. In this thesis, ... -
Design and implementation of the crypto-assistant: an eclipse plugin for usable password-based column level encryption based on hiberate and jasypt
(2013-03-01)The lack of encryption of data at rest or in motion is one of the top 10 database vulnerabilities according to team SHATTER [72]. In the quest to improve the security landscape, we identify an opportunity area: two tools ... -
Design and performance evaluation of data dissemination and hovering information protocols for vehicular ad hoc networks (VANETs)
(2017-07-01)Robust and efficient communication protocols for Vehicular Ad Hoc Networks (VANETs) are still an open topic in the literature. Because of that, our attention has been gathered by the Data Dissemination and the Information ... -
Design by Immersion: A Transdisciplinary Approach to Problem-Driven Visualizations
(IEEE, 2019-08-26)While previous work exists on how to conduct and disseminate insights from problem-driven visualization projects and design studies, the literature does not address how to accomplish these goals in transdisciplinary teams ... -
Detecting vulnerabilities of broadcast receivers in Android applications
(2016-01-01)As being a representative mobile operating system in the world, Android OS has been part of users' daily life. Unfortunately, the rapid expansion of Android third-markets introduces malware aiming at Android applications ... -
Detection of gasoline from internal tissues for use in determining victim status at the time of a fire
(2012-08-01)In Ontario, fire investigators from the Office of the Fire Marshal (OFM) are responsible for determining the origin and cause of suspicious fires. As part of the investigation, fire debris samples are collected from the ... -
Detection of side-channel communication in a mobile ad-hoc network environment using the Hamming distance metric
(2015-06-01)Side-Channel communication is a form of traffic in which malicious parties communicate secretly over a wireless network. This is often established through the modification of Ethernet frame header fields, such as the Frame ... -
Determining optimal flight paths for cellular network connectivity for the transmission of real-time physiological data in support of big data analytics during airborne critical care transport
(2017-02-01)This thesis presents a methodology for determining the optimal flight paths between two geographical points based on distance and cellular reception over the path. This methodology consists of two main concepts: coverage ... -
Determining the differences in effect of chromate, chromite and chromium picolinate in rainbow trout (Oncorhynchus mykiss) at environmentally relevant concentrations
(2021-11-01)The Ring of Fire is a region in the James Bay Lowlands of northern Ontario that houses a rich deposit of chromite and is slated for mining development. The goals of this study were to better understand the relative effects ... -
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 ... -
Determining the impact of carrion decomposition on soil microbial activity levels and community composition.
(2013-12-01)The ubiquitous nature of microorganisms and their specificity to certain locations make them potentially useful for forensic investigators. Advances in microbial profiling techniques have made it possible to compare microbial ... -
Developing an elevated temperature Pourbaix diagram for zirconium and multi-element Pourbaix diagram of Zircaloy-4
(2023-08-01)Zirconium and Zircaloy-4 are used in applications that require corrosion resistance under extreme conditions. For example, the fuel bundles in coolant systems of CANDU™ reactors operate between 533 to 583K (260 to 310 °C). ... -
