Safe Reinforcement Learning For Trajectory Tracking Of Mobile Robots With Minimal Intermittent Observations, Mahtab Noor Shaan

Theses

Autonomous wheeled mobile robots (WMRs) are widely used for safe operation in safety-critical systems, such as robotic visual inspection of confined spaces in energy infrastructure, warehouse automation, delivery robots, and autonomous vehicles. The operating environments for these safety-critical systems are often uncertain. Therefore, in such environments, it is essential for WMRs to reliably follow predetermined paths while effectively maintaining lane position and avoiding collisions. However, frequent observations required for control execution to account for environmental uncertainty result in increased sensing, computation, and energy costs. This necessity drives the research for safe and resource-aware trajectory-tracking control methods. Although several state-of-the-art trajectory …

Information Capacity For Time-Varying Adversarial Networks, Raphael Thorp

Theses

This thesis investigates the capacity of time-varying adversarial networks where intelligent adversaries can corrupt transmissions on restricted subsets of network edges that change availability over time. Building upon the work of Beemer et al. on adversarial network coding with restricted adversaries, we analyze networks whose topology evolves temporally, motivated by applications in space networking and delay-tolerant systems. We introduce different adversarial modes that capture different temporal aspects of corruption behavior and establish their hierarchical relationship with respect to network capacity. The analysis employs time-expanded graph representations and develops recursive counting methods for computing expected network capacity under random time assignments, …

Blockchain Poisoning Attacks In Federated Learning, Mohammad Raihan Uddin

Theses

Federated Learning (FL) enables collaborative model training across distributed clients without sharing raw data, thereby preserving privacy. However, conventional FL depends on a centralized aggregator, exposing it to poisoning and backdoor attacks that threaten model integrity. This thesis introduces B-ZkFed, a blockchain-based and zero-knowledge proof (ZKP)-enhanced FL framework designed to ensure verifiable trust, transparency, and robustness. The blockchain layer decentralizes aggregation through smart contracts, while the ZKP module allows clients to cryptographically prove the correctness of updates without revealing private data. A multi-layer adaptive defense combining gradient-norm filtering, model-similarity analysis, and robust aggregation mitigates poisoning threats under both IID and …

Sigrid Undset: Nordic Catholic Apologist, Brendan Edward Arthur

Theses

This thesis explores the depth and breadth of Sigrid Undset’s non-fiction Catholic writing, a substantial body of work that has largely remained inaccessible to all but readers of Norwegian. Through original translations and analysis, it synthesises these texts into broad themes while situating them within their historical contexts of the intellectual and cultural debates in early twentieth-century Norway. The study addresses three research questions: (1) the general themes in Undset’s Catholic non-fiction; (2) the contemporary relevance of these writings; and (3) whether Undset merits the designation “Catholic apologist.” In its method, the thesis employs textual analysis of Undset’s essays, articles …

Vision Or Exemplification? Augustine And Aquinas On Divine Illumination, Matthew Richard Cain

Theses

Many interpreters of Thomas Aquinas since the second half of the twentieth-century emphasise the Platonist dimensions of his thought, particularly his metaphysics. This contrasts with, and is a shift away from, the dominant Aristotelian interpretations of previous generations. Aquinas’s theory of knowledge, however, tends still to be interpreted in Aristotelian terms, according to which Augustine’s Platonist illuminationism is replaced by a Peripatetic emphasis on sensation and abstraction in the soul.

This thesis reexamines the role of illumination in Augustine and Aquinas’ theories of knowledge. It asks whether scholarship today ought to reconceive the relationship between these two major thinkers in …

What Are Younger ("Millennial" Aged 24 - 40) Secondary Religious Education Teachers In Sydney Catholic Schools Understanding And Experiencing In Terms Of A Call To Witness, Mark Smith

Theses

Teachers of Religious Education in Australian Catholic secondary schools, like teachers of all key learning areas, are expected to have specialist knowledge of the content being taught and skills in contemporary pedagogy for high-quality learning. They also have an additional expectation – they are called to witness to the Catholic faith and Catholic teachings as they teach about them. Or at least they are in theory. However, in a contemporary Australian society that is becoming increasingly non-religious, secular, pluralistic, and religiously diverse is this call to witness still tenable or appropriate? Research on Catholic education has called for a greater …

A Public For The Problem: Vocabularies Of Belonging At The Climate Precipice, Louisa Stredwick

Theses

This study proposes the central concepts of belonging and vocabulary to critically analyse and recompose current approaches to more-than-human relationship that are inadequate and counterproductive. Contemporary vocabularies of belonging are inadequate because they fail to account for the practicalities of an expansive human and more-than-human ‘we’, and they are underpinned by extractivist or idealist logics. They are counterproductive because they carry embedded dualisms that often directly counter intended messages of inherent relationality. A largely theoretical work, the thesis is informed by a field philosophy approach in the Environmental Humanities, working alongside the Martuwarra (Fitzroy) River, in North-Western Australia, and its …
