title: Comparison of two commonly used hydrofoils and their propensity to cavitation and ventilation
Creators: name: Mackenzie, JR
Publisher: name: University of Tasmania
Year: 2021

description: Cavitation occurs when vapour pockets form in a liquid flow because of local pressure reductions. This kind of phenomena can occur on hydrofoils operating in a liquid domain near a free surface (seawater and air) this boundary induces persistent ventilated cavities to form and attach to the hydrofoil surface. As a result, ventilation and cavitation can coexist to reduce the efficiency of a hydrofoil operating in a liquid domain near a boundary (free surface) with air. The objective of the research project is to determine if the same trends can be seen in both cavitation and ventilation propensity for two commonly used hydrofoil sections (NACA-0012 & Mach 2) whilst using realisable design methodologies. The hydrofoils were configured around a typical main foil fitted to a moth sailing dinghy. The cavitation propensity of the hydrofoil sections was analysed numerically by using Computational Fluid Dynamics (CFD) to determine design conditions where cavitation is likely to occur when operating near a free surface. The two-dimensional CFD analysis was performed purely to determine the effect of cross-sectional shape to cause cavitation propensity at certain design conditions. The CFD analysis showed that both hydrofoils had a high reduction in lift and increase in drag when operating at Depth to Chord Ratio (D/C) of one. The proximity relationship with the free surface also showed that cavity length increased as submergence was decreased. The NACA0012 had a greater propensity to cavitation over the design conditions analysed. The ventilation propensity of the hydrofoils was analysed by conducting a full-scale experiment where the number of ventilation events were analysed over a set period. The full-scale experiment showed the existence of ventilation caused by the hydrofoil tip breaking the free surface which allowed a tip vortex to propagate from behind the trailing edge and attached to regions on the upper surface of the hydrofoil. The NACA-0012 experienced this phenomenon on more occasions than the Mach 2 and more importantly had greater period of persistent ventilated cavity attachment on the leading edge. This location of persistent ventilated cavity attachment also coincided to be the same region of maximum cavitation propagation as verified in the CFD results, this is where the NACA-0012 hydrofoil had a higher propensity to operate with cavitation where pressure regions below free surface reached cavitation critical pressure due to cross-sectional shape. The research project has shown that there is a correlation between ventilation and cavitation on a hydrofoil operating near a free surface. The primary focus was to determine common trends and explain the commonality of both phenomena. With such information a designer can use a relatively simple measure of two-dimensional cavitation propensity to help reduce the probability of complex three-dimensional persistent ventilated cavities.

description: $ηNNN$ and $ηNNNN$ bound states are explored in stochastic variational method (SVM) calculations within a pionless effective field theory (EFT) approach at leading order. The theoretical input consists of regulated $NN$ and $NNN$ contact terms, and a regulated energy dependent $ηN$ contact term derived from coupled-channel models of the $N^{\ast}(1535)$ nucleon resonance plus a regulated $ηNN$ contact term. A self consistency procedure is applied to deal with the energy dependence of the $ηN$ subthreshold input, resulting in a weak dependence of the calculated $η$-nuclear binding energies on the EFT regulator. It is found, in terms of the $ηN$ scattering length $a_{ηN}$, that the onset of binding $η\,^3$He requires a minimal value of Re$\,a_{ηN}$ close to 1 fm, yielding then a few MeV $η$ binding in $η\,^4$He. The onset of binding $η\,^4$He requires a lower value of Re$\,a_{ηN}$, but exceeding 0.7 fm.

title: Fugitive identity: an abstraction of persona through the mask, camouflage and material assemblage
Creators: name: Kluss, BD
Publisher: name: University of Tasmania
Year: 2021

description: This research project explores, through a studio-based investigation, a condition of identity that is fugitive in nature – that of a persona – the experience of shifting and mutable roles and contexts framed as an array of literal and metaphorical masks. This condition is explored through a body of work that employs lenticular stencils, termed ‘masks’, to produce disruption patterns that encourage an active and dynamic interplay with the observer, resulting in a tension between the virtual, the real and the actual. An analysis of the mask and strategies of masking (covering, modulating, protecting, dissimulating etc.) are located and discussed within a range of art practices, where the mask is observed to be a material-semiotic actor in a network of relationships that enables the performance of camouflage. Camouflage is introduced and observed as the strategic relating (an active process) between an entity and the parts of the world to which it belongs or dissociates; a fluctuating of the senses between sharpening and blurring that produces an experience of the world that is particular and partial – an umwelt as defined by Jakob von Uexküll. This framework proposes that identity is not to be understood as a static, fixed entity but rather as the product of a series of events or performances that are constantly in flux, as defined by Giles Deleuze in The Logic of Sense (1993). The practical investigation moves through a series of experiments that explore dimensionality within a painting-based practice, employing strategies such as masking, stencilling, cutting, layering, reflecting and repeating; moving from a single picture plane through to multidimensional and assemblage-based works that employ heterogeneous materials and processes focused on the kinetic movement and proprioception of the observer1. This investigation is contextualised through the environmental assemblages of Robert Rauschenberg, the lenticular optics of Victor Vasarely and Lincoln Austin, the persona of Andy Warhol, the technological assemblages of Ivan Navarro, and the camouflaging strategies of Lee Yong Baek, amongst others. It proposes a practical methodology of heterogeneous assemblage, as defined by Manuel DeLanda, in which simple interactions between limited components can produce an infinite array of complexity and potentialities. This has resulted in a body of work employing machine-cut layered stencils, described as lenticular masks, that interfere with human gestalt perception, producing a real and granular encounter with emergence; a becoming real through the interaction of systems, one territory opening onto another, moving from a representation of camouflage towards an active and dynamic performance of camouflage. The shifting apprehensions of pattern recognition in the final works allow for a new understanding of identity; one that is in a state of active camouflage, a fugitive in the mask of a persona.

description: Hip disarticulations and hemipelvectomies are the highest level of lower limb amputations. As such, these amputations create ambulation difficulties and current prosthetic solutions are limited. Powered prosthetic joints have successfully improved lower limb amputee gait; however, no powered hip joints are available on the market. This thesis presents the design and evaluation of a microprocessor-controlled powered hip joint for hip-level amputees. A rope and pulley system was used to transmit power from an actuator located at the prosthetic thigh to rotate the prosthetic leg around an anteriorly-located prosthetic hip joint. The pulley system features an innovative tensioning system using multiple keyways, allowing the system to be tensioned without external tensioning devices. The powered hip prosthesis passed ISO 15032:2000 mechanical strength tests that simulated 100 kg user loads. The joint was also tested by able-bodied individuals using a hip disarticulation simulator to walk with the powered hip-knee-ankle-foot prosthesis. Though the participants had asymmetrical gait with shorter intact-side swing time, the device successfully allowed the participants to ambulate. The final device weighed 3.9 kg and respected geometric design constraints to fit comfortably under pants. Future work is needed to implement a gait control system, resolve a rope slack issue, and test the device with hip-level amputees.

description: In a closely packed ensemble of quantum emitters, cooperative effects are typically suppressed due to the dephasing induced by the dipole-dipole interactions. Here, we show that by adding sufficiently strong collective dephasing cooperative effects can be restored. In particular, we show that the dipole force on a closely packed ensemble of strongly driven two-level quantum emitters, which collectively dephase, is enhanced in comparison to the dipole force on an independent non-interacting ensemble. Our results are relevant to solid state systems with embedded quantum emitters such as colour centers in diamond and superconducting qubits in microwave cavities and waveguides.

title: Old and new : musical characteristics and effects of the Irish folk music movement of the twentieth century
Creators: name: Lamb, BJ
Publisher: name: University of Tasmania
Year: 2021

description: Despite the international success and long careers of Irish ensembles like The Chieftains, The Dubliners, The Clancy Brothers and Planxty, there has been minimal research into the height of their popularity during the Irish folk music movement of 1960 to 1979. Numerous documentaries such as the BBC’s Folk Hibernia (2007), O’Toole’s No Disco (2003) and the various series on key individuals from The Chieftains and The Dubliners have highlighted the cultural and musical significance of these performers, in particular, their influence to change the Irish musical landscape of the mid-twentieth century. The documentaries and literature on these performers acknowledge a clear relationship between tradition and innovation amongst these ensembles with an Irish musical identity central to this new sound. However, they do not provide detailed analysis and reflection on how these changes occurred and what were the key features introduced during this time. This study identifies a clear catalyst for this musical movement within Ireland in Seán Ó Riada and his formation of Ceoltóirí Chualann at the beginning of the 1960s and the popularisation of Irish traditional repertoire in a new medium: the folk orchestra. An analysis of the common musical and instrumental features amongst ensembles during this period reveals two key areas of innovation due to these performers: 1) new instrumentation and collection of new instrumental textures, and 2) progressive arrangement of Irish repertoire including the contribution of original composition to the already sizeable communal body of Irish music. Analysis of the recordings from this period identify these two elements as the most evident aspects of change to Irish music and confirm their presence as a lasting legacy in the Irish musical landscape. Due to the ensemble setting, pioneered by Ó Riada, performers like Johnny Moynihan, Paul Brady, Andy Irvine and Dónal Lunny introduced and adapted instruments like bouzouki, mandolin, and acoustic guitar to suit the nuances of Irish music. Interviews with select performers of this period also provide a unique insight into their creative process and their relationship with Irish repertoire. These perspectives highlight the intrinsic connection of Irish music to these performers and the conscious sensitivity towards creating cultural change in Irish music. Through the exploration inherent in these instrumental choices, these performers also introduced new rhythmic and melodic ideas in an Irish context, further expanding the vocabulary of Irish traditional and folk performance. In identifying these key elements and their musical, social, and cultural contexts, this study will provide greater detail to the body of research around this period and will contribute to future research around Irish music more broadly.

description: When does a Noetherian commutative ring $R$ have uniform symbolic topologies on primes--read, when does there exist an integer $D>0$ such that the symbolic power $P^{(Dr)} \subseteq P^r$ for all prime ideals $P \subseteq R$ and all $r >0$? Groundbreaking work of Ein-Lazarsfeld-Smith, as extended by Hochster and Huneke, and by Ma and Schwede in turn, provides a beautiful answer in the setting of finite-dimensional excellent regular rings. It is natural to then sleuth for analogues where the ring $R$ is non-regular, or where the above ideal containments can be improved using a linear function whose growth rate is slower. This manuscript falls under the overlap of these research directions. Working with a prescribed type of prime ideal $Q$ inside of tensor products of domains of finite type over an algebraically closed field $\mathbb{F}$, we present binomial- and multinomial expansion criteria for containments of type $Q^{(E r)} \subseteq Q^r$, or even better, of type $Q^{(E (r-1)+1)} \subseteq Q^r$ for all $r>0$. The final section consolidates remarks on how often we can utilize these criteria, presenting an example.

description: We analyze the probability distributions of the quantum walks induced from Markov chains by Szegedy (2004). The first part of this paper is devoted to the quantum walks induced from finite state Markov chains. It is shown that the probability distribution on the states of the underlying Markov chain is always convergent in the Cesaro sense. In particular, we deduce that the limiting distribution is uniform if the transition matrix is symmetric. In the cases of non-symmetric Markov chain, we exemplify that the limiting distribution of the quantum walk is not necessarily identical with the stationary distribution of the underlying irreducible Markov chain. The Szegedy scheme can be extended to infinite state Markov chains (random walks). In the second part, we formulate the quantum walk induced from a lazy random walk on the line. We then obtain the weak limit of the quantum walk. It is noted that the current quantum walk appears to spread faster than its counterpart-quantum walk on the line driven by the Grover coin discussed in literature. The paper closes with an outlook on possible future directions.

title: Governing regional industry networks in the knowledge economy : place, policy, and institutions
Creators: name: Johnson, LC
Publisher: name: University of Tasmania
Year: 2021

description: In recent years, growing support has emerged for the idea that place-based development platforms supporting innovation or industrial agglomeration rely on the quality of regional intangible assets and institutions. This thesis examines the ways that embedded, collaborative industry networks function as repositories for this soft infrastructure of regional economic development and investigates how they can be more effectively leveraged by government. These critical roles include diffusing knowledge, pooling common resources, providing high-level representation or advocacy, negotiating or mediating policy and strategic issues for their members, and embedding norms or behavioural expectations, to name just a few. While they may be organised to varying levels of formality, and structured by different institutional factors, these networks provide vital fora for connecting businesspeople, civic actors, public servants, university or higher education representatives, and influential place leaders in the pursuit of shared aims for their industries and regions. Existing scholarship has highlighted the value of these networks and their activities, outlining their central role in place-based economic development platforms that leverage local knowledge bases and capitalise on endogenous advantage. Research has been less successful, however, at systematically explaining the emergence of regional industry networks, articulating policy strategies for promoting them, and describing the implications of different network types or configurations. Given the path dependent and highly context-specific nature of regional industry networks, these issues are an important gap in current approaches. This thesis explores the emergence and institutionalisation, configuration, and governance of three Tasmanian industry networks. The research presented has been conducted in partnership with the Tasmanian Department of Premier and Cabinet on case studies of direct importance to ongoing economic development policy efforts, helping to ensure its relevance and applicability. As well as exploring, in depth, the formation and institutionalisation of the three cases, the thesis adapts the concept of ‘metagovernance’ to explain the roles played by government as a key actor within them. As an aid to better understanding these roles, and the network contexts to which they are most appropriate, this thesis also proposes an original heuristic typology of regional industry networks. The findings thus provide a clear, empirically grounded repertoire of tools available to states responsible for managing and overseeing networked approaches to economic development, as well as conceptual tools with which to understand the strategies best suited to different network types or configurations.

We use the Serre spectral sequence associated to a fiber sequence $\mathbf{B}U_n\rightarrow\mathbf{B}PU_n\rightarrow K(\mathbb{Z},3)$ to determine the ring structure of $H^{*}(\mathbf{B}PU_{n}; \mathbb{Z})$ up to degree $10$, as well as a family of distinguished elements of $H^{2p+2}(\mathbf{B}PU_{n}; \mathbb{Z})$, for each prime divisor $p$ of $n$. We also study the primitive elements of $H^*(\mathbf{B}U_n;\mathbb{Z})$ as a comodule over $H^*(K(\mathbb{Z},2);\mathbb{Z})$, where the comodule structure is given by an action of $K(\mathbb{Z},2)\simeq\mathbf{B}S^1$ on $BU_n$ corresponding to the action of taking the tensor product of a complex line bundle and an $n$ dimensional complex vector bundle.

description: The southern Hikurangi subduction interface represents one of the most significant sources of seismic and tsunami hazard for the Wellington Region. The It’s Our Fault: No Matou Te Hapa programme subduction earthquake task is focused on better understanding the hazard of the southern Hikurangi subduction zone through studies of past earthquakes and tsunami. In this report we present the preliminary results from new investigations at the Wairau Lagoons, near Blenheim, that aim to refine the existing subduction earthquake record from this site and extend the record of earthquakes and tsunami further back in time. Preceded by a period of consultation with mana whenua and obtaining permits for field work, in February 2023 we collected sediment cores from six new locations across the Wairau Lagoons. All cores underwent computerised tomography (CT) scanning and about half the cores have been split open and photographed. From one core (BL23-V7) we obtained 26 radiocarbon ages. The previously observed buried salt marsh soil associated with earthquake-driven subsidence at ~500 years BP was widely observed in cores from across the lagoons. We have not yet obtained more radiocarbon ages to confirm and refine the age of this earthquake. Most cores contain evidence of the previously observed tsunami sand and buried soil dated at 880–800 years BP. New radiocarbon ages provide a preliminary revised age for this earthquake of 858–811 years BP. This small change in the event age may help up to better understand if the subduction zone ruptured with upper plate faults in this earthquake. Prior to ~1000 years BP it appears the lagoon was more connected to the open ocean and deeper. The sediments deposited prior to the 800–880 year BP tsunami are typically homogenous silts and fine sands that are characteristic of intertidal to subtidal embayments. While we had hoped to find locations that preserved sensitive high saltmarsh environments prior to 1000 years BP in our new suite of cores, we have not found this. Despite this, anomalous deposits do exist deeper in the sediment cores and may indicate past sudden changes associated with earthquakes and/or tsunami. These warrant further study and most likely additional core collection. Future work will involve studying the cores that have not yet been opened, submitting more radiocarbon ages and focussing on the anomalous deposits identified deeper in cores BL23-V7 and BL23-V1.

description: Climate change and agricultural intensification are exposing insect pollinators to temperature extremes and increasing pesticide usage. Yet, we lack good quantification of how temperature modulates the sublethal effects of pesticides on behaviours vital for fitness and pollination performance. Consequently, we are uncertain if warming decreases or increases the severity of different pesticide impacts, and whether separate behaviours vary in the direction of response. Quantifying these interactive effects is vital in forecasting pesticide risk across climate regions and informing pesticide application strategies and pollinator conservation. This multi-stressor study investigated the responses of six functional behaviours of bumblebees when exposed to either a neonicotinoid (imidacloprid) or a sulfoximine (sulfoxaflor) across a standardised low, mid, and high temperature. We found the neonicotinoid had a significant effect on five of the six behaviours, with a greater effect at the lower temperature(s) when measuring responsiveness, the likelihood of movement, walking rate, and food consumption rate. In contrast, the neonicotinoid had a greater impact on flight distance at the higher temperature. Our findings show that different organismal functions can exhibit divergent thermal responses, with some pesticide-affected behaviours showing greater impact as temperatures dropped, and others as temperatures rose. We must therefore account for environmental context when determining pesticide risk. Moreover, we found evidence of synergistic effects, with just a 3°C increase causing a sudden drop in flight performance, despite seeing no effect of pesticide at the two lower temperatures. Our findings highlight the importance of multi-stressor studies to quantify threats to insects, which will help to improve dynamic evaluations of population tipping points and spatiotemporal risks to biodiversity across climate regions.

description: Quantum statistics is defined by Hilbert space products between the eigenstates associated with state preparation and measurement. The same Hilbert space products also describe the dynamics generated by a Hamiltonian when one of the states is an eigenstate of energy E and the other represents an observable B. In this paper, we investigate this relation between the observable time evolution of quantum systems and the coherence of Hilbert space products in detail. It is shown that the times of arrival for a specific value of B observed with states that have finite energy uncertainties can be used to derive the Hilbert space product between eigenstates of energy E and eigenstates of the dynamical variable B. In these Hilbert space products, quantum phases and interference effects appear in the form of an action that relates energy to time in the experimentally observable dynamics of localized states. Quantum effects emerge in the measurement statistics when the precise control of energy in quantum state preparation results in a coherent randomization of the dynamics, such that two different arrival times contribute to the quantum statistics of the same measurement outcome B. The non-classical features associated with quantum interference can thus be explained as a consequence of quantum dynamics and its role in state preparation and measurement, indicating that the apparent randomness of control described by the energy-time uncertainties is not merely a technical problem but rather originates from the fundamental nature of interactions between physical systems.

description: Proteins are a major interface between the genotype and phenotype of living things. Understanding the structure of these molecules, and how their structure interacts with their sequence and function, is vital to our knowledge of all life. Specifically, knowledge of protein structure evolution has a multitude of applications in health and biology, as it could allow us to accurately predict the effects of any protein mutation and use this knowledge for drug discovery and to combat disease. Protein structural relationships and changes can be effectively mapped using a network, with the proteins represented as nodes and connections between them indicating degree of similarity or possible evolutionary relationships. Many different approaches to determining where these connections should lie have been presented, with all producing complex pictures of the protein universe. However, constructing a model of protein structural change that captures enough physical and chemical information to make accurate predictions remains a major challenge. With this ultimate goal in mind, I present three original studies that contribute to our understanding of protein structure. The first is a benchmarking study of protein structure alignment methods, with efficacy assessed through their ability to determine levels of structural similarity between protein domains and to cluster domains into those of equivalent structure. Sorting proteins by structure is relevant to many biochemical problems, including constructing networks based on structural similarity. The second study assesses the completeness of our current understanding of protein structure space by focusing on triplets of secondary structure elements. Determining whether or not the current Protein Data Bank (PDB) contains all structures of proteins will give an idea of the level of novelty we can expect in a complete network of protein evolution. The third study looks at the relationships between contact density, protein age and protein sequence diversity. These are all potential contributors to determining possible evolutionary links between proteins. Also, relationships between these variables could result in patterns of similarity in networks that could otherwise be explained through convergent or divergent evolution. It is our hope that the results of this work will inform future network-based representations of the protein universe.

description: The advent of time domain astronomy is revolutionizing our understanding of the Universe. Programs such as the Catalina Real-time Transient Survey (CRTS) or the Palomar Transient Factory (PTF) surveyed millions of objects for several years, allowing variability studies on large statistical samples. The inspection of $\approx$250k quasars in CRTS resulted in a catalogue of 111 potentially periodic sources, put forward as supermassive black hole binary (SMBHB) candidates. A similar investigation on PTF data yielded 33 candidates from a sample of $\approx$35k quasars. Working under the SMBHB hypothesis, we compute the implied SMBHB merger rate and we use it to construct the expected gravitational wave background (GWB) at nano-Hz frequencies, probed by pulsar timing arrays (PTAs). After correcting for incompleteness and assuming virial mass estimates, we find that the GWB implied by the CRTS sample exceeds the current most stringent PTA upper limits by almost an order of magnitude. After further correcting for the implicit bias in virial mass measurements, the implied GWB drops significantly but is still in tension with the most stringent PTA upper limits. Similar results hold for the PTF sample. Bayesian model selection shows that the null hypothesis (whereby the candidates are false positives) is preferred over the binary hypothesis at about $2.3σ$ and $3.6σ$ for the CRTS and PTF samples respectively. Although not decisive, our analysis highlights the potential of PTAs as astrophysical probes of individual SMBHB candidates and indicates that the CRTS and PTF samples are likely contaminated by several false positives.

description: We prove several results on torsion points and Galois representations for complex multiplication (CM) elliptic curves over a number field containing the CM field. One result computes the degree in which such an elliptic curve has a rational point of order $N$, refining results of Silverberg. Another result bounds the size of the torsion subgroup of an elliptic curve with CM by a nonmaximal order in terms of the torsion subgroup of an elliptic curve with CM by the maximal order. Our techniques also yield a complete classification of both the possible torsion subgroups and the rational cyclic isogenies of a $K$-CM elliptic curve $E$ defined over $K(j(E))$.

description: Robot introspection, as opposed to anomaly detection typical in process monitoring, helps a robot understand what it is doing at all times. A robot should be able to identify its actions not only when failure or novelty occurs, but also as it executes any number of sub-tasks. As robots continue their quest of functioning in unstructured environments, it is imperative they understand what is it that they are actually doing to render them more robust. This work investigates the modeling ability of Bayesian nonparametric techniques on Markov Switching Process to learn complex dynamics typical in robot contact tasks. We study whether the Markov switching process, together with Bayesian priors can outperform the modeling ability of its counterparts: an HMM with Bayesian priors and without. The work was tested in a snap assembly task characterized by high elastic forces. The task consists of an insertion subtask with very complex dynamics. Our approach showed a stronger ability to generalize and was able to better model the subtask with complex dynamics in a computationally efficient way. The modeling technique is also used to learn a growing library of robot skills, one that when integrated with low-level control allows for robot online decision making.

description: In the narrow-line Seyfert 1 galaxy 1H 0707-495, recently a transient quasi-periodic oscillation (QPO) signal with a frequency of $\sim 2.6\times 10^{-4}$ Hz has been detected at a high statistical significance. Here, we reanalyze the same set of XMM-Newton data observed on 2008 February 4 with the Weighted-Wavelet Z-transform (WWZ) method. In addition to confirming the previous findings, we also find another QPO signal with a frequency of $\sim 1.2\times 10^{-4}$ Hz in a separated X-ray emission phase at the significance level of $\sim 3.7σ$. The signal is also found fitting an auto-regressive model though at a lower significance. The frequency ratio between these two signals is $\sim 2:1$. The analysis of other XMM-Newton measurements of 1H 0707-495 also reveals the presence of the $\sim 2.6\times 10^{-4}$ Hz ($\sim 1.2\times 10^{-4}$ Hz) QPO signal on 2007 May 14 (2010 September 17) at the significance level of $\sim 4.2σ$ ($\sim 3.5σ$). The QPO frequency found in this work follows the $f_{QPO}-M_{BH}$ relation reported in previous works spanning from stellar-mass to supermassive black holes. This is the first time to observe two separated transient X-ray QPO signals in active galactic nuclei (AGNs), which sheds new light on the physics of accreting supermassive black holes.
