Learning And Planning For Autonomous Systems With Emergent Hierarchical Representations And Decaying Short-Term Memory, Piotr Aleksander Bogdan Jan 2023

Learning And Planning For Autonomous Systems With Emergent Hierarchical Representations And Decaying Short-Term Memory, Piotr Aleksander Bogdan

School of Engineering, Computing and Mathematics Theses

How do we create machines with the ability to capture, record and recall memories of past experience? How should these machines choose the most optimal action based on those stored memories? These seem like crucial questions for creating intelligent machines capable of learning from experience. The field of Artificial Intelligence (AI) is trying to reproduce such capabilities with increasing success. Currently a large portion of AI algorithms are focusing on making decisions based on big sets of learned past experience examples in the form of instantaneous input-output mapping. They operate as discrete models where time is collapsed into independent signal …


Graphene-Based Biosensors For Quantitative Characterisation Of Dna Methylation, Mina Safarzadeh Jan 2023

Graphene-Based Biosensors For Quantitative Characterisation Of Dna Methylation, Mina Safarzadeh

School of Engineering, Computing and Mathematics Theses

DNA methylation is associated with various diseases including cancer, cardiovascular diseases and neurodegenerative disorders, making it a potential biomarker to diagnose and prognose these diseases. Hence, a tool to detect and quantify DNA methylation can be valuable to improve clinical tests. In this thesis, we report two different biosensors for the detection and quantification of methylated tumour suppressor gene, O-6-methylguanine-DNA methyltransferase (MGMT), which is a potential biomarker for brain tumours and breast cancer. Both of the reported biosensors in this thesis are based on screen-printed reduced graphene oxide electrodes (rGO SPEs) and are electrochemical biosensors. In the Ab/ssDNA biosensor the …

Flaws In The Methodologies For Organic Carbon Analysis In Seagrass Blue Carbon Soils, Oscar Serrano, Ines Mazarrasa, James W. Fourqurean, Eduard Serrano, Jeffrey Baldock, Jonathan Sanderman

Research outputs 2022 to 2026

The ability to accurately measure organic carbon (OC) in marine sediments or soils is overall taken for granted in scientific communities, yet this seemingly mundane task remains a methodological challenge when the soil matrix contains calcium carbonate (CaCO3), creating inaccuracies in Blue Carbon estimates. Here, we compared five common methods combining acidification, combustion, and wet oxidation pre-treatments for determination of OC in sediments and soils containing CaCO3 based on the analyses of artificial soil mixtures made of different OC and CaCO3 contents, and multiple soils from Australian seagrass cores. The results obtained showed that methods involving acidification pre-treatment entailed −17 …

Investigating The Perspectives Of Older Adults In Residential Aged Care On Oral Health-Related Quality Of Life, Parisa Malekpour, Amanda Devine, Julie Dare, Leesa Costello

Research outputs 2022 to 2026

Objective

The objective of the study was to explore how older people living in a residential aged care facility perceived that their oral health influenced their food preferences and attitudes towards food, their social interactions and their self-esteem.

Background

Poor oral health can have biological, behavioural and social impacts on quality of life among older adults (aged 65+ years). In terms of biological impacts, oral health impairments may cause older adults to avoid many types of foods. This shift in dietary pattern can lead to malnutrition among older people, undermine general health and negatively impact quality of life (QOL).

"Having It Both Ways: Containing The Champions Of Feminism In Female-Led Origin And Solo Superhero Films", Jessica Taylor, Laura Glitsos Jan 2023

"Having It Both Ways: Containing The Champions Of Feminism In Female-Led Origin And Solo Superhero Films", Jessica Taylor, Laura Glitsos

Research outputs 2014 to 2021

In this article, we consider the emerging trend of solo, female-led superhero films, and their repeated location in aesthetically distinct pasts or “closed moments.” This pastness, we contend, serves to distinguish the concerns of the protagonists, which are often read as feminist, as redundant for the contemporary audience. This framing is in keeping with a postfeminist cultural context, wherein feminist values and successes are celebrated, while simultaneously declared irrelevant.

We examine the historical or closed settings in Wonder Woman (2017), Wonder Woman 1984 (2020), Captain Marvel (2019) and Black Widow (2021), and consider how this collective investment in the past …

Mining For Sleep Data: An Investigation Into The Sleep Of Fly-In Fly-Out Shift Workers In The Mining Industry And Potential Solutions, Gemma Maisey

Theses: Doctorates and Masters

Shift work in the mining industry is a risk factor for sleep loss leading to impaired alertness, which may adversely impact health and safety risks. This risk is being increasingly recognised by leaders and shift workers in the mining industry, however, there is limited knowledge available on the extent of sleep loss and other potential contributing factors. Furthermore, knowledge of the efficacy of individual interventions to assist shift workers to improve their sleep, and the management of risk at an organisational level is scarce. This PhD thesis involved three studies. The first two studies involved the recruitment of 88 shift …


Comparative Study On Development Of Novel Catalytic Oxidation For Removing Emerging Contaminants, Abdul H. Asif Jan 2023

Comparative Study On Development Of Novel Catalytic Oxidation For Removing Emerging Contaminants, Abdul H. Asif

Theses: Doctorates and Masters

‘Wastewater treatment’ is not itself a new concept, where global water bodies have been polluted since the evolution of mankind. As a result of human activities including domestic, industrial and commercial practices, levels of water pollution through aqueous contaminants are increasing every day. Moreover, rapid industrialisation and recent human progress has given rise to a new classification of pollution, that of emerging contaminants (ECs). Further, these chemicals are highly resistant to biodegradation and are capable of travelling, where they can penetrate from one part of the world to another. Whilst traditional wastewater treatment techniques, such as adsorption, might be effective …

Towards Establishing A Fit-For-Purpose Regulatory Framework For Radiation Protection In Western Australia's Mining Industry: Evaluating Mine Worker Exposures To Naturally Occurring Radionuclides, Martin I. Ralph

Theses: Doctorates and Masters

Mining in the state of Western Australia (WA) formally commenced in the 1840s, and over the ensuing 180 years has evolved to be the epicentre of the Australian mining industry and a significant contributor to the national economy. The lithology of WA is replete with mineralisation that hosts uranium and “critical minerals” required for the global renewable energy sector. The state’s first uranium mine is under development, and high levels of activity are occurring in the state’s nascent critical minerals sector, with 168 WA-based companies pursuing rare earths-bearing minerals, 51 of which are actively drilling on their tenements.

WA’s mineral …


Experiments And Modelling Into Air Staging In A Fixed Bed Biomass Combustor, Awais Junejo Jan 2023

Experiments And Modelling Into Air Staging In A Fixed Bed Biomass Combustor, Awais Junejo

Theses: Doctorates and Masters

Combustion of biomass to produce heat and electricity has increased recently due to environmental concerns over the use of fossil fuels. Being CO2 neutral, biomass has the potential to replace solid fossil fuels, such as coal, in thermal power plants. Direct combustion of biomass is the most widely used thermochemical process to generate heat and electricity.

In staged biomass combustion, primary air is supplied beneath the fuel bed, with secondary air then provided above in the freeboard region. The freeboard can be divided into primary freeboard length (LI), which is upstream of secondary air, and a secondary freeboard length (LII), …


Decoding The Mechanism Of Hypertension Through Multiomics Profiling, Eric Adua Jan 2023

Decoding The Mechanism Of Hypertension Through Multiomics Profiling, Eric Adua

Research outputs 2022 to 2026

Hypertension, characterised by a constant high blood pressure, is the primary risk factor for multiple cardiovascular events and a major cause of death in adults. Excitingly, innovations in high-throughput technologies have enabled the global exploration of the whole genome (genomics), revealing dysregulated genes that are linked to hypertension. Moreover, post-genomic biomarkers, from the emerging fields of transcriptomics, proteomics, glycomics and lipidomics, have provided new insights into the molecular underpinnings of hypertension. In this paper, we review the pathophysiology of hypertension, and highlight the multi-omics approaches for hypertension prediction and diagnosis.


Ecohydrology Of Coastal Aquifers In Humid Environments And Implications Of A Drying Climate, Madeleine Dyring, Harald Hofmann, David Stanton, Patrick Moss, Ray Froend Jan 2023

Ecohydrology Of Coastal Aquifers In Humid Environments And Implications Of A Drying Climate, Madeleine Dyring, Harald Hofmann, David Stanton, Patrick Moss, Ray Froend

Research outputs 2022 to 2026

Coastal groundwater-dependent ecosystems (GDEs), such as wetlands, estuaries and mangrove forests, are globally important habitats that promote biodiversity, provide climate regulation and serve as refugia for plant and animal communities. However, global warming, coastal development and over-abstraction threaten the availability and quality of groundwater in coastal aquifers and, by extension, the ecohydrological function of dependent ecosystems. Because ecohydrological knowledge of coastal groundwater is disparate across disciplines and habitat types, we begin by summarising the physiochemical, biological and hydrological processes supported by groundwater across coastal watersheds. Groundwater makes a significant but poorly recognised contribution to the function and resilience of coastal …


Effects Of Perpetrator And Victim Gender, Rape Myths, And Report Timing On Blame Attributions Following Sexual Assault, Katherine E. Kennon Jan 2023

Effects Of Perpetrator And Victim Gender, Rape Myths, And Report Timing On Blame Attributions Following Sexual Assault, Katherine E. Kennon

College of Graduate Studies: Theses & Dissertations

Previous research examined the effects of victim gender, perpetrator gender, and rape myth acceptance on victim blaming attribution; however, fewer studies explore victim and perpetrator gender at the same time, and even fewer studies examined the relevance of factors like timing of reporting (immediate or delayed) or rurality. The primary purpose of the study, therefore, was to explore the effect of victim gender, perpetrator gender, and report timing (same day vs. six months later) on victim blaming attributions. The study also examined the role of rape myth acceptance on victim blame and compared levels of rape myth acceptance across participant …

Research Datasets

We conducted trial ScanEagle drone surveys of dugongs in Shark Bay, Western Australia, covering the full extent of the drone’s range (~ 100 km), concurrently with observer surveys, with drone flying above or just behind the piloted aircraft. We aimed to test the assumption that drone imagery could provide comparable detection rates of dugongs to human observers when influenced by same environmental conditions. Data in "All data for analysis - Shark Bay Hodgson et al" include a summary of the sightings from both platforms per transect segment, including associated environmental covariates. Also included are details of each dugong group sighted …


Role Of Cardiopulmonary Interactions In Development Of Ventilator-Induced Lung Injury-Experimental Evidence And Clinical Implications, Neel Shah, Bhushan H Katira Jan 2023

Role Of Cardiopulmonary Interactions In Development Of Ventilator-Induced Lung Injury-Experimental Evidence And Clinical Implications, Neel Shah, Bhushan H Katira

2020-Current year OA Pubs

Ventilator-induced lung injury (VILI) impacts outcomes in ARDS and optimization of ventilatory strategies improves survival. Decades of research has identified various mechanisms of VILI, largely focusing on airspace forces of plateau pressure, tidal volume and driving pressure. Experimental evidence indicates the role of adverse cardiopulmonary interaction during mechanical ventilation, contributing to VILI genesis mostly by modulating pulmonary vascular dynamics. Under passive mechanical ventilation, high transpulmonary pressure increases afterload on right heart while high pleural pressure reduces the RV preload. Together, they can result in swings of pulmonary vascular flow and pressure. Altered vascular flow and pressure result in increased vascular …

The Strong Families Program: Utility Of Telehealth Parenting Skills Psychoeducation, Grace C. Prosperi Jan 2023

The Strong Families Program: Utility Of Telehealth Parenting Skills Psychoeducation, Grace C. Prosperi

College of Graduate Studies: Theses & Dissertations

Externalizing behaviors in children are a common problem experienced by many parents. If untreated, externalizing behaviors are associated with more serious consequences (Hann, 2012). Parents of children with behavior issues also report higher levels of stress (Dumas et al., 2009). Parenting stress is related to lower life satisfaction for parents and increased negative outcomes for children living in the home. Parent training programs, incorporating attachment building and discipline strategies, combat childhood externalizing behaviors in clinical settings. While reducing childhood externalizing behaviors is the main aim of parent training, there are other benefits to gaining parenting skills such as increased familial …

Research outputs 2022 to 2026

Abiotic and biotic factors influence seagrass resilience, but the strength and relative importance of the effects are rarely assessed over the complete lifecycle. This study examined the effects of abiotic (salinity, temperature, water depth) and biotic (grazing by black swans) factors on Ruppia spp. over the complete lifecycle. Structures were set up in two estuaries ( – 33.637020, 115.412608) that prevented and allowed natural swan grazing of the seagrasses in May 2019, before the start of the growing season. The density of life stage(s) was measured from June 2019 when germination commenced through to January 2020 when most of the …

Williams, Dinoop Ravindran Menon, Derek Smith, Jonathan Mayer, Anna Reid, Joanne Domenico, Giang Huong Nguyen, William A. Robinson, Melanie Ziman, Dexiang Gao, Zili Zhai, Mayumi Fujita

Research outputs 2022 to 2026

Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is an immune checkpoint expressed in regulatory T (Treg) cells and activated T lymphocytes. Despite its potential as a treatment strategy for melanoma, CTLA-4 inhibition has limited efficacy. Using data from The Cancer Genome Atlas (TCGA) melanoma database and another dataset, we found that decreased CTLA4 mRNA was associated with a poorer prognosis in metastatic melanoma. To investigate further, we measured blood CTLA4 mRNA in 273 whole-blood samples from an Australian cohort and found that it was lower in metastatic melanoma than in healthy controls and associated with worse patient survival. We confirmed these findings …

A Survey On Artificial Intelligence-Based Acoustic Source Identification, Ruba Zaheer, Iftekhar Ahmad, Daryoush Habibi, Kazi Y. Islam, Quoc Viet Phung

Research outputs 2022 to 2026

The concept of Acoustic Source Identification (ASI), which refers to the process of identifying noise sources has attracted increasing attention in recent years. The ASI technology can be used for surveillance, monitoring, and maintenance applications in a wide range of sectors, such as defence, manufacturing, healthcare, and agriculture. Acoustic signature analysis and pattern recognition remain the core technologies for noise source identification. Manual identification of acoustic signatures, however, has become increasingly challenging as dataset sizes grow. As a result, the use of Artificial Intelligence (AI) techniques for identifying noise sources has become increasingly relevant and useful. In this paper, we …

Research outputs 2022 to 2026

Depression is a common and debilitating condition for which effective treatments are needed. Lepidium meyenii Walp (Maca) is a plant with potential medicinal effects in treating depression. Recently, there has been growing interest in plant-derived extracellular vesicles (EVs) due to their low toxicity and ability to transport to human cells. Targeting the gut–brain axis, a novel strategy for depression management, may be achieved through the use of Maca-derived EVs (Maca-EVs). In this study, we successfully isolated Maca-EVs using gradient ultracentrifugation and characterized their shape, size, and markers (CD63 and TSG101). The in vivo imaging showed that the Dil-labeled Maca-EVs crossed …

Research outputs 2022 to 2026

Although pathogenic variants in PSEN1 leading to autosomal-dominant Alzheimer disease (ADAD) are highly penetrant, substantial interindividual variability in the rates of cognitive decline and biomarker change are observed in ADAD. We hypothesized that this interindividual variability may be associated with the location of the pathogenic variant within PSEN1. PSEN1 pathogenic variant carriers participating in the Dominantly Inherited Alzheimer Network (DIAN) observational study were grouped based on whether the underlying variant affects a transmembrane (TM) or cytoplasmic (CY) protein domain within PSEN1. CY and TM carriers and variant non-carriers (NC) who completed clinical evaluation, multimodal neuroimaging, and lumbar puncture for collection …

Human In Vivo Medial Gastrocnemius Gear During Active And Passive Muscle Lengthening: Effect Of Inconsistent Methods And Nomenclature On Data Interpretation, Matheus Daros Pinto, Kazunori Nosaka, James M. Wakeling, Anthony J. Blazevich

Research outputs 2022 to 2026

‘Muscle gear’ is calculated as the ratio of fascicle-to-muscle length change, strain, or velocity. Inconsistencies in nomenclature and definitions of gear exist across disciplines partly due to differences in fascicle [curved (Lf) versus linear (Lf,straight)] and muscle [whole-muscle belly (Lb) versus belly segment (Lb,segment)] length calculation methods. We tested whether these differences affect gear magnitude during passive and active muscle lengthening of human medial gastrocnemius of young men (n=13, 26.3±5.0 years) using an isokinetic dynamometer. Lb, Lb,segment, Lf and Lf,straight were measured from motion analysis and ultrasound imaging data. Downshifts in belly gear but not belly segment gear occurred with …
