Title of Thesis:‘ Enhancing Microscale Thermal Management with Advanced Carbon Nanostructure Integration.’
This thesis investigates ways to improve cooling systems in advanced electronics by examining both passive methods, such as micro heat pipes, and active methods, like microchannel heat sinks. By integrating advanced materials, including graphene and carbon nanotubes, the study identifies optimal designs to boost heat transfer efficiency. It also balances critical goals, such as achieving maximum cooling performance while minimizing energy losses from entropy generation and pressure drops. The results highlight significant gains in cooling efficiency, offering valuable strategies for better thermal management in high-performance electronics and energy systems.

Title of Thesis:‘ Lower Limb Control Architecture To Assist Sit-To-Walk Transitions.’
Sit-to-walk is a fundamental daily activity. However, aging or movement impairments deteriorate STW thus, reducing mobility, increasing fall risk, and negatively impacting quality of life. Assistive devices have gained significance for supporting compromised STW, where their effectiveness depends on their underlying control architecture. This thesis develops a personalised control architecture by integrating movement initiation detection and joint torque prediction models, tailored for individual body characteristics and movement strategies. This generates timely, effective, and more natural assistance during STW transitions for older adults and individuals in rehabilitation.

Title of Thesis:‘ Integrated Oil Emulsion-Ionic Liquid Air Flotation for Microalgae Harvesting.’
This thesis investigates the viability of ionic liquids as an alternative surfactant to the conventional CTAB and the performance of integrating an oil emulsion into the air flotation process to enhance microalgae harvesting efficiency, as well as enhancing the dewatering process by reducing water recovery during the harvesting process thus leading to higher biomass concentration in the harvest.

Title of Thesis:‘ Point Cloud-based Vehicle Monitoring Systems using Deep Learning.’
Point clouds produced by scanning devices such as LIDAR( Light Detection and Ranging) devices accurately maps the shape of objects and their surroundings. The use of deep learning with point cloud data focuses on object detection, semantic segmentation, and classification to accomplish safety-critical robotic perception applications such as autonomous vehicles and industrial measurement systems, requiring large amounts of computational resources and model training time. This thesis proposes efficient solutions for three-dimensional point cloud detection for vehicles, three-dimensional point cloud segmentation for indoor and outdoor spaces, and a methodology for the classification of vehicle presence utilizing compact two-dimensional point cloud sensors.
