This body of work is the culmination of a part-time five year investigation into the use of mirroring in digital art composition and its potential to generate affective intensity.The research has occurred through a series of installative works and artefacts produced with digital media in which mirrored operations have been employed in a variety of different ways. The aim of these explorations was to develop and articulate a compositional approach based in acts of mirroring, with the aim of extending affective invitations to the viewer.

This research investigates an innovative approach to augmenting the current evaporation pond disposal approach used in Australia, and other regions around the world. The augmentation involves the incorporation of solar plate collector technology. The technology is widely used across the world to collect solar power to drive a range of commercial and domestic applications, most commonly solar hot water systems.

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.

This research is built upon the determination of the Eigenpairs of one and two dimensional positive differential operators with periodic boundary conditions. The Schrödinger equation was solved for positive operators in both one and two dimensions. Fourier series were used to express the derivatives as the summation of Fourier terms. This led to a novel approach for the calculation of the eigenmodels of a perturbed potential well. The perturbation can be done via an electric field applied to the potential well.

This is a qualitative collective case study that seeks to understand the phenomena of graffiti and its related subcultures. By employing Interpretivist techniques, the research attempts to raise questions about harm minimisation, zero tolerance and graffiti, as well as broaden the debate about these distinct policy approaches for local communities. The research setting encompasses the geographic area of the Knox municipality, situated in outer eastern Melbourne.

The research question was: In what ways can multi-media enrich the telling of stories from an Indigenous point of view? Other important examinations of this research are: Analysis of the process of previous projects, and the effect these have had on participants - why have past approaches not been effective? How can this project learn from those mistakes? How can a researcher facilitate consultation and create community engagement within Aboriginal communities? What are the outcomes of ‘Pitcha This’? How can a community utilize the outcomes of the project?

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 aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.

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.

The aim of this Masters of Engineering (MEng) - Aerospace thesis was to investigate the durability of Piezoelectric Wafer Active Sensors (PWAS) for the health monitoring of composite structures. One significant challenge faced by the aviation industry is the cost and time associated with maintaining aircrafts, in particular, aging airliners. Structural Health Monitoring (SHM) is a possible approach to reduce the high cost of inspection and maintenance.

Objective: Objective of this dissertation is to find a novel method to reduce computation cost as well as memory requirement but still retain accuracy in video-based person ReID approach. In video-based person ReID, computation cost and memory requirement are the two main issues. Working with a large number of images is the burden of any surveillance system. This results in a high computation cost as well as a large memory capacity.
