Semi-direct visual SLAM for stereo cameras: system design and validation
(2021-11-01)
Simultaneous Localization and Mapping (SLAM) requires an autonomous vehicle in an unknown environment to learn about the environment, generates a map and localize itself at the same time. To solve this problem, various ...
Tunable compact microwave multiplexers based on substrate integrated waveguide
(2021-05-01)
Microwave multiplexers and diplexers are widely used in communication systems. This thesis presents a compact low-profile hybrid-coupled filter module (HCFM) implemented using substrate integrated waveguide (SIW). Compared ...
Health and safety enhancement of lithium-ion batteries for fast-charging
(2021-08-01)
With the ever-increasing demand for battery electric vehicles, the expectation of safety, range, and fast charging has become a major focus for industry players and researchers. The research presented herein sought to ...
A CFD analysis of the pressure drop through misaligned Stirling engine regenerators
(2021-04-01)
Experiments were conducted to discover the average misalignment in wire mesh regenerators, and it was found that regardless of the intended stacking arrangement, the average misalignment was 44% to 49%. A 3-dimensional CFD ...
Modelling and real-time simulation of a modular bidirectional solid-state transformer for ultra-fast charging of electric vehicles
(2021-08-01)
This thesis proposes a modular Solid-State Transformer (SST) system architecture to be directly interfacing with a three-phase MV utility network enabling high-power and ultra-fast charging capabilities for electric vehicles, ...
Design and evaluation of solar and geothermal energy systems integrated with Cu-Cl cycle
(2020-09-01)
This thesis study proposes solar and geothermal based three multigeneration systems. System 1 consists of a bifacial photovoltaic (BiPV) plant, multi-effect distillation (MED) desalination unit and, proton exchange membrane ...
Electrical impedance tomography for internal radiation therapy
(2021-08-01)
Internal radiation therapy is a radiation-based treatment for various forms of localized cancer. In this treatment, several needles or catheters are inserted percutaneously into the tissue, and radiation is delivered through ...
Development of waste management systems: applications of Durham Region
(2021-08-01)
This thesis aims to reduce environmental impacts and increase overall efficiencies of domestic waste management systems by proposing case studies for Durham Region. Case study 1 integrates an anaerobic digestion facility ...
Application-specific transfer learning over edge networks
(2021-11-01)
Transfer learning uses a profound labeled set of data from the source domain to deal with a similar problem for the target domain. Transfer learning provides accurate decision- making when insufficient data samples are ...
Fast algorithm for joint unicast and multicast beamforming in large-scale systems
(2021-09-01)
We consider a joint unicast and multi-group multicast beamforming problem for massive multiple-input multiple-output (MIMO) system with a large number of unicast users. We propose an alternating direction method of multipliers ...
