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 ...
Investigation and use of dual (twin) low pressure proportional counters for active neutron-gamma mixed field dosimetry
(2023-05-01)
This thesis tackles accurate neutron-gamma mixed field dosimetry in radiation protection and radiation biology. While passive dosimeters are suitable for measuring low radiation levels, active instruments are necessary in ...
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 ...
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 ...
Categories in control systems software: toward a unified theory of programming & control
(2023-12-01)
Category theory is applied to the design and modeling of control systems application software with emphasis on feedback control. The language of application is iso standard C++17, though the design is abstract and can be ...
Automatic trajectory generation for mobile-manipulators using 3D LiDAR scans of unknown surfaces
(2019-07-01)
An approach to improving worker safety in underground uranium drift mining through automating the radiation scanning and shotcrete application process is presented. Utilizing the Robot Operating System (ROS) framework to ...
