Development And Testing Of A Rotating Detonation Rocket Engine With A Racetrack Combustor And Shear-Coaxial Injectors, Evan Colson Unruh

Theses

Rotating Detonation Engines (RDEs) have the potential to provide higher propulsive performance compared to conventional deflagrative combustors. The objective of this study is to compare liquid propane (LC3H8) and gaseous methane (GCH4) fuels in a laboratory-scale RDE. To accomplish this objective, a 4-inch, “racetrack” type RDE was developed that facilitates optical access to the combustion region. Fuels are injected, along with gaseous oxygen (GO2), using 50 discrete GO2-centered shear-coaxial injector elements. The design approach for the engine is discussed including combustor channel sizing, injector selection, ignition method, and instrumentation. Counter-propagating detonation waves were observed during testing with average wave velocities …

A Theology Of Confirmation From The Canon Of Scripture, Peter Pellicaan

Theses

In the last forty years, scholars have commonly referred to confirmation as the “sacrament in search of a theology.” While various works have offered a theology of confirmation in recent years, they have not employed an explicitly biblical method. In contrast, the early Church Fathers and ecclesiastical writers engaged an biblical method by employing a typological interpretation of scripture in order to understand baptism and the eucharist. In this sense, circumcision, the crossing of the Red Sea and the waters referred to in the creation narrative have been understood as prefiguring baptism; the Passover inaugurated by Moses in Egypt is …

How Changes In Group Size Impact Teachers’ Perceptions Of Their Practice In Australian Centre-Based Early Childhood Education And Care Services, Michelle Hilton-Moon

This study draws on the theory of change to establish its aim, which is to identify the impact a change in group size had on these teachers’ perceptions. Issues pertaining to the teachers’ perception of the child and their perception of their roles as teachers are explored through a phenomenological case study approach. The contemporary theoretical perspectives of Erica Burman, Lillian Katz, Nel Noddings and Max van Manen provide theoretical propositions (predetermined themes) to examine the …

Is There A Catholic Theology Of Masculinity?, Peter Holmes

Theses

In recent times Catholic theologians have begun to speak of a ‘feminine genius’. Yet relatively little attention given to the unique and positive contribution of masculinity and manhood to relationships, the Church and society. This thesis aims to answer the question, “Is there a corresponding ‘masculine genius?” It attempts to synthesise a specifically Catholic understanding of masculinity from the magisterial teaching of the Catholic Church, to determine a basis for development of the Catholic understanding of masculinity and to propose some lines of development for Catholic theology in this area.

Chapter One will establish the need for and purpose of …

A Study Of Paragraph Five In Caritas In Veritate: Re Understanding Relationality, Self Gift And Love, William Corbishley

Theses

Along with Deus Caritas Est and Spe Salvi, Pope Benedict XVI in Caritas in Veritate provides a Christological response to the suffering in the world. In Paragraph 5 of CIV is a particular call to Christians to meet their responsibilities to love God and their neighbour in the broader human community. CIV 5 embeds the task for each Christian to accept the logic of truth of God's Love for their lives and build a relationship with God through the Person of Jesus Christ. Accepting this truth generates responses where people in self-gift love the other and constitute instruments of grace …

Ovarian cancer is the second most common gynaecological cancer and the eighth-most common cause of death in Australian women with a five-year relative survival of 46%. Using a ‘ground-up approach’ and patient involvement, this research project implemented a sequential mixed methods approach to develop a health-related quality of life outcome measure across the disease trajectory.

The six key themes identified from initial qualitative data highlighted treatment-related and psychosocial challenges alongside financial issues, relationships with health professionals, and patient coping strategies. This informed the generation of items necessary to develop a draft health-related quality of life tool. A cognitive interviewing technique …

Prisoners, Power And Panopticon: Investigating Fremantle Gaol, 1831-1841, Emily Lanman

Theses

The history of crime and punishment is intertwined with Australia’s colonisation, including the foundation of the Swan River Colony in 1829. It can be demonstrated that Jeremy Bentham’s writings on criminal reform, specifically through his work on the panopticon model prison, influenced the development of punishment and prisons in the colony. This is evident in the construction of Fremantle Gaol (1831), which was built on the principles set forth by the panopticon and provides an interesting insight into what was deemed important in the penal system the colony continued to establish between 1831 and 1841. While Fremantle Gaol conformed to …

Defining The Potential Of Gene Therapy With Bone Morphogenetic Proteins As A Novel Therapeutic Approach In Parkinson’S Disease, Susan Rebecca Goulding

Theses

Parkinson’s disease is a neurodegenerative disorder, characterised by the progressive degeneration of midbrain dopaminergic neurons, and the intracellular aggregation of the α-synuclein protein in neurons throughout the nervous system. These changes result in the characteristic motor impairments in Parkinson’s disease. Current treatments are solely symptomatic and therefore there is an unmet clinical need to develop new disease-modifying therapies that can alter disease progression. For over 25 years, one proposed experimental therapy has focused on the delivery of proteins called neurotrophic factors to the brain to prevent dopaminergic neuron degeneration. However, to date, clinical trials using the most well-known neurotrophic factors …

Dynamics Of A Swept Source Laser Under External Injection, Uday Bangavadi Munivenkatappa

Theses

Swept Sources are lasers with a periodically modulated frequency, over a wide scanning range. They are widely used in Optical Coherence Tomography (OCT) for medical imaging and metrology. The narrow instantaneous linewidth of a swept source is required for longer OCT imaging depths. The goal of the project is to investigate the mechanism that deteriorates the coherence of a swept-source laser by analyzing its properties under external injection and investigate the possibilities for a phase-locked laser operation, in order to control the coherence properties. The laser under study was a semiconductor ring fiber-based cavity laser, incorporating a tunable narrow transmission …

Wavelength Swept Photonic Crystal Laser, Sharon Marie Butler

Theses

Photonics has become integral to society, based on its ability to sense the environment, to manipulate materials and to transport information. The dominance of silicon electronics has made silicon photonics a compelling vision, but difficulties with light emission have caused delays in implementation and an enduring role for III-V materials. The research conducted in this Ph.D. thesis involves study and utilisation of a combination of the optical gain of Indium Phosphide with the precision and energy of silicon nanophotonics in a novel family of lasers. A continuously tunable akinetic reflective filter is exploited to obtain a wavelength swept laser. The …

Photoluminescence Properties Of Novel Iii-V Semiconductor Systems, Shumithira Gandan

Theses

Perturbation of the inherent radiation equilibrium in solids by an external energy could engender an emission of the superfluous energy as electromagnetic radiation, or luminescence. Photoluminescence methods precipitate this disintegration of radiation equilibrium often by supplying the external energy as photons with energies higher than the bandgap energy of the solid. Since the excitation energy momentarily transforms the medium before luminescence is emitted, photoluminescence experiments are able to produce diverse and intricate spectroscopic data detailing the optical properties of the solid as a measure of this transformation. The pliability of allowed electron states in semiconductors have instigated bourgeoning research in …

Predicting Carcass Cut Yields In Cattle From Digitalimages Using Artificial Intelligence, Darragh Matthews

Theses

Beef carcass classification in Europe is predicated on the EUROP grid for both fatness and conformation. Although this system performs well for grouping visually similar carcasses, it cannot be used to accurately predict meat yields from these groups, especially when considered on an individual cut level. Deep Learning (DL) has proven to be a successful tool for many image classification problems but has yet to be fully proven in a regression scenario using carcass images. Here we have trained DL models to predict carcass cut yields and compared predictions to more standard machine learning (ML) methods. Three approaches were undertaken …

The Role Of Software Engineering In Bioinformatics, Brendan Sean Lawlor

Theses

This thesis proposes that by applying state-of-the-art software engineering tools, techniques and frameworks to currently recognised challenges in bioinformatics, improved outcomes can be attained in that field. It begins by decomposing software engineering into two categories, namely process and architecture, and choosing two key challenges in the practice of bioinformatics: reproducibility and scalability. The body of the thesis is an exploration of the intersection between these two software engineering categories and these two bioinformatics challenges. The question is asked: Can best practices in professional software engineering be applied to address key issues in the bioinformatics domain, creating positive outcomes? And …

The care towards the end of life is an important aspect of patient management. There is a recognised need to support healthcare providers in caring for dying patients in the acute hospital.(1-5) The Liverpool Care Pathway was originally designed to provide guidance in the delivery of comprehensive palliative care in the last days of life. However, there are no robust clinical data supporting the use of the Liverpool Care Pathway despite its widespread implementation worldwide.(6, 7)

This study investigated whether implementation of an end of life care pathway, adapted from the Liverpool Care Pathway, increases the frequency of prescriptions of …

The Art Of Fiction: Fact, Myth And New Knowledge On The North Australian Expedition, 1855 - 1857, Stevie Cole

Theses

This thesis determines the degree to which the North Australian Expedition, 1855–1857, contested established European fiction of the Australian frontier by systematically collecting new knowledge. It analyses the outcomes of one of the most forgotten expeditions in Australian history by interrogating the journals, charts and artworks of the explorers. In 1855, the Royal Geographical Society and the British Colonial Office sent an expedition into northern Australia under the command of Augustus Gregory. It was a region that Britain hoped would hold lucrative resources to support further economic and population development. The artist-explorer, Thomas Baines, was made second-in-command of the expedition. …

The Experiences That Form And Sustain Generation Y Religious Education Coordinators In Catholic Secondary Schools, Dirk Gleghorn

Theses

Students in Western Australian Catholic schools learn about Catholic beliefs and practices in the Religious Education Learning Area. In Catholic secondary schools, Religious Education Coordinators (RECs) are delegated responsibility from principals, to coordinate the teaching of this learning area’s content. RECs are required to be committed Catholics who are active members of the Catholic Church. It is probable that RECs will increasingly be recruited from amongst Generation Y Catholics. For Catholic secondary school principals, recruiting religiously committed Generation Y Catholics into the position of REC will be challenging.

The primary aim of the research is to identify and describe the …

Adaptive Uplink Data Rate Prediction And Networkselection In A Vehicular Mobile Channel, Georgi Nikolov

Theses

The rapid acceleration into the digital age brings a worldwide interconnectedness of an unprecedented level. This interconnectedness transforms the modern transportation network by linking its infrastructure components (e.g., signaling systems, traffic control systems, maintenance systems) together. Intelligent transportation systems (ITS) can utilize this newly emerged network infrastructure, improving traffic safety, traffic control, and reducing transportation-related environmental impacts, changing the way drivers, businesses and governments deal with road transport. It is expected that in the near future self-aware vehicles (e.g., trains, cars or trucks) will constitute the majority of the transportation infrastructure. Vehicles need to be able to reliably communicate critical …

Comparison Of The Effects Of Land Use / Land Cover On Water Quality And The Intertidal Marine Macroalgae Communities At The Fluvial Outflows Of The Dingle Peninsula, Cassandra Lew

Theses

The Milltown, Feohanagh, and Owenmore river basins located on the Dingle Peninsula in Ireland were studied to see how variation in land use and land cover (LU/LC) affected water quality and the macroalgal communities at each river’s respective fluvial outflow. Abundance and composition of macroalgae in river and coastal water bodies have been designated as an indicator of water quality according to the Water Framework Directive 2000. The results of this study found that the Feohanagh’s macroalgal community had the highest species richness for most months while the Milltown had the highest Shannon Diversity Index. The Owenmore’s community was consistently …

Crop Salinity Tolerance Induction Using Novel Biostimulants (Saltibio), Elomofe Ikuyinminu

Theses

Salinity is one of the major abiotic stresses affecting crop production, especially in arid and semi-arid areas. Most of the vegetable crops are salt sensitive, growing inadequately in salinised soils due to the accumulation of toxic ions from prolonged, inadequate irrigation programs. A meaningful approach to counteract salinity stress and increase crop yield is the use of protein hydrolysate biostimulants (PHBs). The main objectives of this study were to generate legume-derived PHBs by enzymatic hydrolysis, evaluate their ability to induce salinity stress tolerance in plants, and understand their mode of action. A full compositional and structural analysis of the generated …

Large-Scale Renewable Energy Penetration – A Quantitative Analysis Of Political Determinants Of Renewable Energy And Its Impact On Electricity Price Volatility Transmission And Corporate Financial Performance, Abdul Abban

Theses

This thesis presents four studies on renewable energy. In this thesis, we analyse the political determinants of renewable energy investment in Chapter 2, evaluate the interaction effect between government system and governance quality on renewable energy investment in Chapter 3, estimate the impact of renewable energy on electricity prices and volatility transmission across the Australian regional markets in Chapter 4 and finally investigate the bi-directional causation between environmental and financial performance in Chapter 5.

The findings from Chapter 2 show that both the left and central-orientated governments promote renewable energy investment more than the right-orientated government. Although the presidential system …

Heidegger: The Forgottenness Of Beyng, Emile Alexandrov

Theses

Martin Heidegger’s Contributions to Philosophy (Of the Event) is the first of a series of seven works centred on his concept of the Event (Ereiginis). It is also considered to be his second major work after Being and Time. Written in a form often cited as not fit for publication, it nevertheless exhibits the blueprint for Heidegger’s famous Turn (Kehre). The emphasis of this historical study lies in recognising the contemporaneous manifestation of the “Abandonment by beyng” in its destructive capacity. The nihilistic individual is at the core of this Abandonment, which showcases Heidegger’s description of the individual during the …

The Great Southern Buy-Back: The Colony Of Western Australia And The Great Southern Railway 1880-1897, Thomas Goode

Theses

This thesis examines the circumstances surrounding the building of the Great Southern Railway as a land-grant railway in the colony of Western Australia in the 1880s and its purchase by the government in 1896. In the early 1880s the steamship companies bringing mail and passengers from overseas and the eastern colonies, preferred Albany to Fremantle, adding an uncomfortable three to four day journey to the capital Perth. To overcome this difficulty, the government proposed to build a railway from Albany to the existing network at Beverley. This railway was to be funded by grants of land to the private company …

How The Catholic Church’S Trinitarian-Christocentric Theology Of Communion Might Inform The Way In Which Spouses Are Formed For The Apostolate Of Family Life, Joshua Bitting

Theses

This project explores the nature and mission of the Christian family viewed theologically as a domestic Church. Drawing upon the Catholic Church’s robust Trinitarian and Christocentric communio theology, it is the aim of this endeavour to demonstrate how a robust Trinitarian anthropology, complemented by a culture-first approach, may pave the way for an ongoing marriage catechumenate that will equip spouses to embrace and put into effect the universal call to holiness and mission expressly called for by the Second Vatican Council and contemporary popes.

The first part of the project will articulate the biblical, historical, and theological foundations upon which …

Procedural Fairness Requirements In Decision-Making: Legal Issues And Challenges For Government Secondary School Principals In New South Wales, Tryon Francis

Theses

The application of the rules of procedural fairness, which is an element of administrative law, is an area of law that has not been previously examined in the context of government (public) secondary school principals in New South Wales (‘NSW’). Using a basic qualitative case study design, this study sought to discover the processes that these principals undertook in applying the rules of procedural fairness when managing student discipline, special education and industrial relations. The study examined to what extent New South Wales government (public) secondary school principals were equipped to make decisions that are consistent with the administrative law …

Self-Defence In New South Wales In Its Historical Context: A Simpler Test?, Mamdouh Elmaraazey

Theses

The right to use force in self-defence is recognised by law. The idea of self-defence in criminal law history can be traced back to medieval England’s daily life and ‘the peace’ that the king was trying to establish as his contribution to the good of English society as a whole. The Crown enacted several statutes during the medieval period to ensure that those responsible for homicides were convicted, but would occasionally pardon offenders when the jury qualified their guilty decisions with self-defence explanations. But because the king did not always grant a pardon, juries developed a reputation for handing down …

Understanding The Relationship Between Income And Voting: Are One Nation Voters Influenced By Economic Factors?, Glenda Bourne

Theses

While economic voting has been analysed in detail in international studies, the phenomenon has been under-studied in the Australian context. This dissertation investigates the link between economic voting and the minor party vote in Australia by analysing the vote share for One Nation in Queensland at the 2016 Senate election and 2017 state election. Using linear regression, the relationship between income, unemployment and the One Nation vote proves to be statistically significant, but the relationship does not apply to areas with large populations of Indigenous people or voters from non-English speaking backgrounds. This study offers broad insights into the link …
