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 ...
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 ...
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 ...
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 ...
The aeroacoustics response and shear layer dynamics of confined cavities subject to low Mach number turbulent flow
(2023-04-01)
Cavities exposed to low Mach number flow in various engineering applications are often liable for generating flow-excited acoustic oscillations, resulting in large acoustic amplitudes and vibrations. This compromises the ...
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 ...
