Development and characterization of electrically conductive thermoplastic based composite materials for fuel cell bipolar plates
(2022-08-01)
Thermoplastic composites exhibit multiple attractive attributes, such as lightweight, low cost, ease and speed of manufacturing, and ability to recycle, which make them ideal for a wide range of applications. Composites ...
The feasibility, acceptability, and usability of seated Tai Chi exergame among frail older adult with mild dementia or Parkinson’s disease: a pilot study
(2023-07-01)
Background: For frail older persons with Parkinson's disease (PD) and mild dementia, Tai Chi (TC) is a popular form of exercise. However, due to accessibility issues and negative outcomes, not all movements are suitable ...
Subgraph classification through neighborhood pooling
(2023-06-01)
Subgraph classification is an emerging field in graph representation learning where the task is to classify a group of nodes (i.e., a subgraph) within a graph. Graph neural networks (GNNs) are the de facto solution for ...
Scalable subgraph representation learning through simplification
(2023-06-01)
Link prediction on graphs is a fundamental problem. Subgraph representation learning approaches (SGRLs), by transforming link prediction to graph classification on the subgraphs around the links, have achieved state-of-the-art ...
Design and control of an active ankle-foot orthosis
(2022-04-01)
Active ankle-foot orthoses (AAFOs) assist a user unable to dorsiflex the ankle joint. The optimal AAFO is lightweight and aids the user in achieving a nominal gait.
This thesis presents the design and control of a novel ...
Are we where we should be? Assessing investigative interviewing practices and training of officers in the Force Criminal Investigation Department of the Nigeria Police Force
(2023-06-01)
In the criminal justice system, investigative interviewing is crucial for getting information that helps law enforcement agencies resolve cases. While there is a relative wealth of scholarly studies on investigative ...
Modelling and prediction of tire-rim slip with finite element analysis
(2023-07-01)
In this thesis, tire-rim slip was simulated with a FEA model of a RHD truck tire. Multiple simulations were conducted to validate the model and investigate the effects of different parameters such as terrain type, tire-rim ...
Design and analysis of a sustainable energy system for a military base in the Canadian Arctic
(2023-08-01)
The purpose of this thesis was to propose and thermodynamically analyze a sustainable energy system for a military base in the Canadian Arctic for heating, electricity, farming, fresh water, hot water and waste management. ...
Modified wavelet-based pulse width modulation technique for cascaded H-bridge multilevel converter
(2023-08-01)
Power electronics (PE) converters are crucial for providing a cost-effective, reliable, and efficient solutions for integrating renewable energy sources (RES) into the electrical grid. Over the years, many converter ...
Detector positioning in a field-deployable limited-angle gamma ray emission tomography system
(2023-08-01)
Imaging techniques have been part of the medical and industrial fields for more than a century due to their simple use in the inspection of internal parameters without sample damage. These methods take advantage of the ...
