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 ...
Integrated traffic analysis and visualization for future road events
(2023-04-01)
The existing traffic simulation methods are limited to specific synthetic scenarios. In addition, the natural structure of traffic and accident data requires modeling the dependent observations on multiple levels. Therefore, ...
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 ...
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 ...
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 ...
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 ...
Is implementing a provincial e-cigarette tax associated with a lower likelihood of e-cigarette initiation among high school students? Evaluating the experience in British Columbia using data from the COMPASS study, 2018-2021
(2023-04-01)
Background: This study evaluated the impact of an e-cigarette tax in British Columbia (BC) on youth e-cigarette use.
Methods: This study used repeat cross-sectional and longitudinal samples of students attending high ...
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 ...
AI Adventure Camp: developing critical thinking and ethical artificial intelligence literacy through design fiction and digital constructionism
(2023-04-01)
Artificial intelligence is an increasingly influential aspect of our lives. From GPS to Siri and Amazon Echoes, our data is collected, stored, and analyzed throughout the day. Despite the ubiquity of AI, most STEM curricula ...
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 ...
