Experimental and numerical investigation of the flow structures at the rear of three-dimensional bluff bodies
(2023-05-01)
Flows around bluff bodies have complex structures, which create drag, surface contamination and stability issues for transportation systems. The standard Ahmed body (SAB) is a simplified representative three-dimensional ...
Investigation into the stability of low-inertia micro-grids
(2023-05-01)
This work examines the stability of low inertia micro-grids (MGs). The lack of inertia in such power electronics dominated grid is a pressing matter that directly impacts its operation and stability. The investigated MG ...
An investigation into Manganese(2+) interferences and retrospective dose assessment of shelled species using EPR spectroscopy
(2023-05-01)
High intensity Mn²⁺ peaks in calcified tissues of shells are known to impact the lower dose detection limit in retrospective electron paramagnetic resonance (EPR) studies. This thesis investigates the factors causing Mn²⁺ ...
Design of a residential air source heat pump for extremely cold climates
(2023-05-01)
Air source heat pumps are energy efficient systems suitable for space heating applications, however, their performance drastically degrades in low ambient temperatures. An innovative design is proposed in this thesis that ...
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 ...
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. ...
Design and development of reusable feature-based next-generation embedded software
(2023-12-01)
The emergence of next-generation embedded systems, emphasized by their shortened life cycles, necessitates an urgent shift towards agile software design and development. The objective is to achieve timely product delivery ...
Design and development of a context-aware collaborative autonomous real-time vehicle systems framework
(2023-11-01)
The increasing autonomy of intelligent systems, with applications extending from self-driving vehicles to home-based robots, has emerged as a critical area of focus in modern research. Yet, to acknowledge the full potential ...
Enhancing meta-heuristic algorithms using center-based sampling at population level
(2023-11-01)
In recent years, center-based sampling has demonstrated impressive results to enhance the efficiency and effectiveness of meta-heuristic algorithms. The strategy of center-based sampling can be utilized at either the ...
