Solubility parameters of carbon quantum dots (CQDs) are important physical properties to deploy CQDs in various applications such as organic light emitting diodes (OLEDs), light-converting materials in LEDs, and photoluminescent sensors for metal ion detection. Because of the low toxicity and tunable emission most CQDs have been designed to be water-soluble and biocompatible; oilsoluble CQDs that are essential for OLEDs are not yet explored.

Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

The study determines the predominant hydrogeological controls on salinity distribution and salinization/freshening, proposing conceptual models to explain the different vertical distributions of groundwater salinity at the coastline. An improved understanding of the sources of salinity and the hydrogeological controls will subsequently provide support for the future management of groundwater in the Western Port Basin, and serve as a template for how to unravel complex salinity distributions in coastal aquifers, and their relationships to palaeo- and recent geomorphological histories.

Model Predictive Control (MPC) refers to a class of algorithms that optimize the future behavior of the plant subject to operational constraints. The merits of the class algorithms include its ability to handle imposed hard constraints on the system and perform on-line optimization. This thesis investigates design and implementation of continuous time model predictive control using Laguerre polynomials and extends the design approaches proposed in to include intermittent predictive control, as well as to include the case of the nonlinear predictive control.

The main focus of this thesis is on the application of a model predictive control (MPC) method to devise an ABS for a BBW vehicle. Unlike the traditional ABS control algorithms which are based on a trial and error method, the MPC based ABS algorithm aims to utilizes the behaviour of the model to optimize the wheel slip dynamics subject to system constraints. Performance of the proposed wheel slip controller is validated through Software-in-the-Loop (SiL) and Hardware-inthe-Loop (HiL) simulation.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

This research work first aims to develop a microgrid architecture integrating dispatchable and non-dispatchable distributed generation units in a series-cascaded manner. Existing control strategies for cascaded microgrids focus on dispatchable type generation only. However, adequate power sharing and voltage regulation of a microgrid containing mixed dispatchable and non-dispatchable cascaded generation units demand new control approaches to achieve operational performance and reliability comparable to the conventional parallel-topology microgrid.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

In this thesis, the limitations of using existing LTE congestion mitigation mechanisms such as Discard Timer and RED have been explored. A different mechanism to analyse the effects of using control theory for congestion mitigation has been developed. Finally, congestion mitigation in LTE networks has been addresses using radio resource allocation techniques with non-cooperative game theory being an underlying mathematical framework.

This study develops an online unmanned UAV path-planning strategy for autonomous search and localisation of RF emitter. The UAV is equipped with Receiver Signal Strength (RSS) sensors to localise stationary radio frequency (RF) emitter. A high-fidelity non-linear measurement model of RF propagation in an urban environment is adopted for this purpose. The measurement model of the likelihood function is considered a Gaussian mixture.

The current research is undertaken by performing Computational Fluid Dynamics (CFD) simulations for a 2D aerofoil fitted with a shock control bump at a transonic flow condition. Reynolds-Averaged Navier-Stokes equation coupled with turbulence models is adopted to solve the flowfield. The bump has a conventional geometric feature which consists of a ramp, a crest and a tail, and it has eight variants for which the designed parameters are reasonably specified according to the compressible aerodynamics theory.
