Robust multi-group multicast beamforming design and antenna selection for massive MIMO systems
(2023-04-01)
In this dissertation, we use an Alternating Direction Method of Multipliers (ADMM) algorithm to design robust multi-group multicast beamforming scheme for massive multiple-input multiple-output (MIMO) systems for two ...
Development and assessment of integrated powering systems with alternative fuel choices for clean transportation
(2023-04-01)
This thesis presents novel engine systems using alternative fuels for aviation, rail, and marine transportation as follows: (i) alternative powering systems, such as fuel cells, on-board hydrogen production (ii) alternative ...
Design of surface micro-machined inertial MEMS sensor with meta-heuristic topology optimization
(2023-03-01)
Micro-Electro-Mechanical Systems (MEMS) are getting popular for a variety of applications due to their small size, low cost, and good performance. MEMS devices are designed by combining simple shapes based on the experience ...
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 ...
An evaluation of a dietary sodium reduction research consortium of five low-and middle-income countries in Latin America
(2023-04-01)
Background: Excess sodium consumption is a risk factor to cardiovascular disease (CVD). In Latin American countries (LAC), CVD rates are high. In LAC, policy development is complex and factors impacting research uptake ...
Performance assessment of Au SERS substrates prepared by deposition of Au nanoparticles on screen-printed SiO2 particle films
(2023-02-01)
Surface-enhanced Raman spectroscopy (SERS) is a highly studied technique for simple and rapid trace analysis. Screen-printing, a low-cost fabrication method, has been proposed as a reproducible and affordable approach for ...
Metabolic, neurotoxic and immunotoxic effects of PFAAs and their mixtures on the proteome of plasma and head kidney from rainbow trout
(2023-03-01)
PFAAs (Perfluoroalkyl acids) are a class of bioaccumulative, persistent and ubiquitous aquatic contaminants. A paucity of toxicological information exists for short chain PFAAs and PFAA mixtures. In order to address these ...
Design and evaluation of GAN-based models for adversarial training robustness in deep learning
(2023-04-01)
Adversarial attacks show one of the generalization issues of current deep learning models on special distribution shifted data. The adversarial samples generated by the attack algorithm can introduce malicious behavior to ...
Promoting self-determination amongst youth in conflict with the law: are advocates doing their part?
(2023-01-01)
This thesis used data from eleven advocacy reports published between 1998-2017 in the province of Ontario. The reports ranged from specific youth facilities such as the Roy McMurtry and Hamilton Wentworth centers to reports ...
Optimizing relational search with embedded neural network
(2023-04-01)
Our research focuses on a novel method to query relational data. We propose the partial tuple search problem where a user can utilize keyword search to explore complex relational datasets. The challenge of evaluation of ...
