The analysis of tool wear mechanisms in dry machining of pre-sintered zirconia dental crowns (2024)
Thesis

The purpose of this thesis was to summarise what knowledge has been gained and what has been learnt through entirety of this doctorate on wear mechanisms in the machining of presintered zirconia used in the dental and medical industries. In the denta... Read More about The analysis of tool wear mechanisms in dry machining of pre-sintered zirconia dental crowns.

Investigation of flow augmentation and dynamic stall control devices as performance enhancement of lift-driven vertical axis wind turbine using high-fidelity CFD methods (2022)
Thesis

This study performs an investigation of dynamic stall control (Gurney flap (GF)) and flow augmentation (straight upstream deflector (SUD)) devices to improve the performance of lift-driven Vertical Axis Wind Turbine (VAWT) as they can improve the pow...

Development of adaptive control methodologies and algorithms for nonlinear dynamic systems based on u-control framework (2020)
Thesis

Inspired by the U-model based control system design (or called U-control system design), this study is mainly divided into three parts.
The first one is a U-model based control system for unstable non-minimum phase system. Pulling theorems are prop... Read More about Development of adaptive control methodologies and algorithms for nonlinear dynamic systems based on u-control framework.

Analysis of the spin dynamics of a single-engine low-wing aeroplane (2019)
Thesis

As spinning is still involved in around 60% of all aircraft accidents (BFU, 1985 and Belcastro, 2009), this aerodynamic phenomenon is still not fully understood. As U.S. and European Certification Specifications do not require recoveries from fully d... Read More about Analysis of the spin dynamics of a single-engine low-wing aeroplane.

Dynamic mesh framework for morphing wings CFD (2019)
Thesis

In this work, a framework to perform high fidelity Computational Fluid Dynamics (CFD) analysis of dynamically morphing airfoils and wings is presented. An unsteady parametric method to model the deforming motion is proposed and then implemented in a... Read More about Dynamic mesh framework for morphing wings CFD.

Mathematical modelling and analysis on male urine flow rate (2019)
Thesis

Troublesome voiding lower urinary tract symptoms (LUTS) are a common problem in men, particularly with ageing. Management of voiding LUTS can be guided by accurate determination of underlying mechanisms, distinguishing men with voiding symptoms cause...
