Applications Of Reservoir Simulation And Machine Learning In Subsurface Energy Systems For Decarbonization, Seyedmohammadmehdi Nassabeh

Theses: Doctorates and Masters

The transition to a low-carbon future necessitates innovative approaches to carbon management and hydrogen storage, particularly in the context of enhanced oil recovery (EOR) from hydrocarbon reservoirs. This study employs advanced analytics and machine learning techniques to optimize carbon management strategies. One key focus of this research is to evaluate the effectiveness of flue gas and CO2 in Water Alternating Gas (WAG) injection within a homogeneous fractured carbonate reservoir characterized by low porosity and permeability. A computational model was developed to depict the flow regime in the reservoir and simulate reservoir fluid behavior using Eclipse (E300) software, various hybrid EOR …

Return Serve: Exploring The Dialogism Of The Australia-China Relationship In Media Coverage Between 2020-2022, Jordan Hogan

Theses: Doctorates and Masters

Australia and the People’s Republic of China (PRC) have a dynamic bilateral relationship that is defined by interdependency and mutual political scepticism. This thesis provides an analysis of Australian and Chinese news media perspectives on this relationship. Via an in-depth examination of opinion pieces from national press, I map the significant developments of a period of deteriorating relations between 2020 and 2022. My study captures the more prominent, parochial and vitriolic media coverage of the unravelling relationship, and investigates the motivations, developments, differences, and similarities in the online publications of Australia’s national daily newspaper The Australian, and China’s Global Times. …

The Enigmatic Pianist Arthur Friedheim: A Revised Biography And Study Of His Training, Performing, Writings, Teaching And Editions, Nicholas Mark Williams

Theses: Doctorates and Masters

Arthur Friedheim (1859–1932) was one of the most notable pianists of the late nineteenth century, best remembered as a devoted pupil and disciple of Franz Liszt (1811–1886). Following Friedheim’s Leipzig debut in 1884, Liszt predicted that his young pupil “would yet become the greatest piano virtuoso of the age.” During his lifetime, Friedheim would be compared with such pianistic giants as Carl Tausig (1841–1871), Moriz Rosenthal (1862–1946) and Ferruccio Busoni (1866–1924). Yet his posthumous reception, based on a few surviving recordings and a small number of written sources, has tended to cast doubt on his importance. Some critics disparagingly dismissed …

Modelling The Impacts Of Recreational Catch-And-Release Variability On Fish Stock Dynamics, Brett Crisafulli

Theses: Doctorates and Masters

Recreational fisheries often lack sufficient data for robust stock assessments, and post-release mortality (PRM) of discarded fish, particularly demersal species, poses a significant threat to sustainability. Because demersal fish often experience higher PRM (often due to barotrauma and stress), the substantial global interest in their recreational fisheries (e.g., Australia, Gulf of Mexico, Western Baltic Sea) raises conservation concerns. This study employs three distinct modelling approaches, applied to four reef-dwelling demersal species, to support effective recreational fisheries management by addressing data uncertainty, unintended consequences of management changes, and PRM effects. Specifically, this thesis (1) evaluates variability in average weights of recreationally-caught …

The First International Study Into The Characteristics And Statistical Effectiveness Of Treatment For Indigenous And First Nations People Who Have Sexually Offended: A Meta-Analysis And Survey Of Routine Practice, James Finney

Theses: Doctorates and Masters

Psycho-criminological literature has continued to examine post-treatment recidivism outcomes homogeneously for people who have sexually offended. Because results indicate clear differences between Indigenous and non-Indigenous people who have sexually offended, this project set out to understand the characteristics and effectiveness of treatment for Indigenous and First Nations people from four jurisdictions: Australia, New Zealand, Canada and the United States. A strategic three study strategy was implemented and resulted in a systematic narrative synthesis, meta-analysis and survey of sexual offender treatment organisations in Australia. The systematic review used a comprehensive and scientifically rigorous approach to identify studies (k = 14) that …

The Rise Of Women In Mining - How To Improve Inclusion And Diversity Through Organisational Programs, Ashley Mcgrath

Theses: Doctorates and Masters

The inclusion and diversity (I&D) of women has become a priority for organisations due to the positive association with business performance and rising expectations of employees and shareholders for fair outcomes for all genders. Improving the I&D of women is also being driven by the evolving Australian legal framework which has heightened the responsibility of organisations regarding psychological safety and the prevention of sexual harassment and sex-based discrimination. Companies operating in male dominated industries in Western Australia (WA) are under particular pressure due to lagging performance in addressing equity issues at a state level. Existing research correlates the I&D of …

Optimal Bag Valve Mask Ventilation Efficacy Of Smart Bag Ventilation Compared To Traditional Adult And Paediatric Bag Valve Ventilation During Cardiopulmonary Resuscitation, Ian Dawson

Theses: Doctorates and Masters

Background: Out-of-Hospital Cardiac Arrest (OHCA) is one of the world’s leading causes of mortality. Survival rates are low, ranging from 3.1–20.4% internationally. The most effective oxygenation method for patients during pre-hospital cardiac arrest is ventilating using a self- inflating Bag-Valve-Mask (BVM). Yet, extensive research has identified a lack of compliance with ventilator guidelines during OHCA cardiopulmonary resuscitation (CPR). As a result, clinicians often ventilate patients too aggressively using the BVM, delivering breaths excessively higher than the International Liaison Committee on Resuscitation (ILCOR) recommended rate of 10 breaths per minute (BPM). Hyperventilation can lead to complications such as aspiration, barotrauma, and …

Early, Standardised, And Precise Treatment Of Copd Exacerbations And Covid-19, Sanjay Ramakrishnan

Theses: Doctorates and Masters

Background: Background Chronic Obstructive Pulmonary Disease (COPD) is a common chronic condition causing significant morbidity and mortality. Patients with COPD report sudden episodes of deteriorating respiratory symptoms called exacerbations, often presumed to be precipitated by infections. COPD is in the top 5 causes of death globally. COPD exacerbations drive a large proportion of these deaths. Despite this, there is no standardised model of care for the sickest patients who need hospitalisations for exacerbations. Meanwhile, treatment for COPD exacerbations continues to be guided by symptoms, instead of underlying biology. Most patients are treated with unnecessary and harmful systemic corticosteroids. During the …

The Interplay Between Injury And Body Composition With Performance In Police Recruits, Vanessa Sutton

Theses: Doctorates and Masters

The occupational demands of policing are challenging and potentially hazardous, with substantial rates of musculoskeletal injuries occurring during recruit training. Academy injury prevalence can be as high as one in five recruits. Injuries impact performance, result in lost training, and impose financial burdens on police agencies. However, limited research has explored pre-injury body composition or musculoskeletal characteristics in relation to police recruit performance. This thesis investigates injuries, body composition and musculoskeletal characteristics in physical performance and injury risk among law enforcement recruits.

Study One quantified prevalence and severity of pre-academy injuries and association with performance. Among 121 recruits, nearly half …

Embodied Ai For Challenging Rearrangement Tasks In The Context Of Service And Assistive Robots, Mariia Khan

Theses: Doctorates and Masters

Embodied AI explores intelligent agents that learn through interaction with their environment, aiming to replicate human-like learning processes. Achieving this requires agents capable of understanding a scene via various sensors, reasoning about their actions, and reacting accordingly. These abilities are necessary for service domestic robots to assist humans in their day-to-day activities. Embodied AI tasks can include but are not limited to: visual exploration, visual navigation, instruction following and embodied question answering, which typically consider static (unchanging) environments, where objects do not move over time. This thesis addresses one of the most challenging Embodied AI tasks – visual room rearrangement, …
