description: Discretionary lane change (DLC) is a basic but complex maneuver in driving, which aims at reaching a faster speed or better driving conditions, e.g., further line of sight or better ride quality. Although many DLC decision-making models have been studied in traffic engineering and autonomous driving, the impact of human factors, which is an integral part of current and future traffic flow, is largely ignored in the existing literature. In autonomous driving, the ignorance of human factors of surrounding vehicles will lead to poor interaction between the ego vehicle and the surrounding vehicles, thus, a high risk of accidents. The human factors are also a crucial part to simulate a human-like traffic flow in the traffic engineering area. In this paper, we integrate the human factors that are represented by driving styles to design a new DLC decision-making model. Specifically, our proposed model takes not only the contextual traffic information but also the driving styles of surrounding vehicles into consideration and makes lane-change/keep decisions. Moreover, the model can imitate human drivers' decision-making maneuvers to the greatest extent by learning the driving style of the ego vehicle. Our evaluation results show that the proposed model almost follows the human decision-making maneuvers, which can achieve 98.66% prediction accuracy with respect to human drivers' decisions against the ground truth. Besides, the lane-change impact analysis results demonstrate that our model even performs better than human drivers in terms of improving the safety and speed of traffic.

description: We consider electroweak corrections to the relation between the running $\overline{\mathrm{MS}}$ mass $m_b$ of the $b$ quark in the five-flavor QCD$\times$QED effective theory and its counterpart in the Standard Model (SM). As a bridge between the two parameters, we use the pole mass $M_b$ of the $b$ quark, which can be calculated in both models. The running mass is not a fundamental parameter of the SM Lagrangian, but the product of the running Yukawa coupling $y_b$ and the Higgs vacuum expectation value. Since there exist different prescriptions to define the latter, the relations considered in the paper involve a certain amount of freedom. All the definitions can be related to each other in perturbation theory. Nevertheless, we argue in favor of a certain gauge-independent prescription and provide a relation which can be directly used to deduce the value of the Yukawa coupling of the $b$ quark at the electroweak scale from its effective QCD running mass. This approach allows one to resum large logarithms $\ln(m_b/M_t)$ systematically. Numerical analysis shows that, indeed, the corrections to the proposed relation are much smaller than those between $y_b$ and $M_b$.

title: Free improvisation in the context of repertoire interpretation : an applied investigation of Derek Bailey’s ballads
Creators: name: Kingston, DP
Publisher: name: University of Tasmania
Year: 2018

description: The purpose of this practice-led research was to investigate the use of free improvisation within the context of repertoire interpretation. Through investigating an historical model in which these two approaches to music making co-exist, my aim was to increase my ability as an improviser and interpreter of original music.
Free improvisation can imply an absence of premeditated organisation and content. Performing a repertoire requires the observance of some fixed material - reconciling these two approaches can therefore prove difficult as each contains seemingly contradictory methodologies. By investigating Derek Bailey’s Ballads, a seminal recording on which these two approaches to music making co-exist successfully, a set of key concepts were derived to inform music making that utilises free improvisation in the course of interpreting repertoire. These concepts provide much needed information on the materials and approaches used within the above musical context, and within free improvisation as a whole - an area of research that has thus far been under-represented within academia.
The weighting of this research is 80% folio and 20% exegesis. The exegesis is comprised of an investigation of Ballads through transcription and analysis, self-reflective analysis investigating the utilisation of the research findings in a practice-led capacity, and discussion of recordings produced throughout the course of this research. The folio consists of commercial and concert recordings made between 2013 and 2017.
Considering Bailey’s key materials and organisational approaches has highlighted the importance of a considered and structured approach when combining free improvisation with repertoire interpretation. Investigating a limited set of materials for an extended duration enables any parameter to be improvised upon - be that material derived from a composition, from an established free improvisatory language, or a combination of the two. Applying this knowledge to the performance of my own compositions has greatly expanded my expressive and interpretative capability. Additionally, this research provides useful information for anyone wishing to investigate Bailey’s improvisatory language in both practical and academic settings.

description: Random walks on graphs are an essential primitive for many randomised algorithms and stochastic processes. It is natural to ask how much can be gained by running $k$ multiple random walks independently and in parallel. Although the cover time of multiple walks has been investigated for many natural networks, the problem of finding a general characterisation of multiple cover times for worst-case start vertices (posed by Alon, Avin, Koucký, Kozma, Lotker, and Tuttle~in 2008) remains an open problem.
 First, we improve and tighten various bounds on the stationary cover time when $k$ random walks start from vertices sampled from the stationary distribution. For example, we prove an unconditional lower bound of $Ω((n/k) \log n)$ on the stationary cover time, holding for any $n$-vertex graph $G$ and any $1 \leq k =o(n\log n )$. Secondly, we establish the stationary cover times of multiple walks on several fundamental networks up to constant factors. Thirdly, we present a framework characterising worst-case cover times in terms of stationary cover times and a novel, relaxed notion of mixing time for multiple walks called the partial mixing time. Roughly speaking, the partial mixing time only requires a specific portion of all random walks to be mixed. Using these new concepts, we can establish (or recover) the worst-case cover times for many networks including expanders, preferential attachment graphs, grids, binary trees and hypercubes.

description: Periocular biometric, the peripheral area of the ocular, is a collaborative alternative to the face, especially when the face is occluded or masked. However, in practice, sole periocular biometric capture the least salient facial features, thereby lacking discriminative information, particularly in wild environments. To address these problems, we transfer discriminatory information from the face to support the training of a periocular network by using knowledge distillation. Specifically, we leverage face images for periocular embedding learning, but periocular alone is utilized for identity identification or verification. To enhance periocular embeddings by face effectively, we proposeConsistent Knowledge Distillation (CKD) that imposes consistency between face and periocular networks across prediction and feature layers. We find that imposing consistency at the prediction layer enables (1) extraction of global discriminative relationship information from face images and (2) effective transfer of the information from the face network to the periocular network. Particularly, consistency regularizes the prediction units to extract and store profound inter-class relationship information of face images. (3) The feature layer consistency, on the other hand, makes the periocular features robust against identity-irrelevant attributes. Overall, CKD empowers the sole periocular network to produce robust discriminative embeddings for periocular recognition in the wild. We theoretically and empirically validate the core principles of the distillation mechanism in CKD, discovering that CKD is equivalent to label smoothing with a novel sparsity-oriented regularizer that helps the network prediction to capture the global discriminative relationship. Extensive experiments reveal that CKD achieves state-of-the-art results on standard periocular recognition benchmark datasets.

title: Gaining in a landscape of loss : the experience of learning and using mindfulness whilst caring at the end of life
Creators: name: Jaffray, LM
Publisher: name: University of Tasmania
Year: 2019

description: Informal palliative caregivers, or those caring for a terminally ill family member or friend, are critical to the provision of quality, sustainable end-of-life care. The support provided by these caregivers is increasingly important, considering an ageing population, higher levels of disease burden and increasing healthcare demands. Adverse impacts of end-of-life caregiving on caregiver health and wellbeing, however, are substantial and well-documented. Despite a twenty-year global consensus calling for more evidence-based caregiver support interventions, patient-focused palliative care research, practice and policy have predominated, overshadowing a focus on caregivers. Evidence-based caregiver support therefore, remains narrow in relation to caregivers’ holistic unmet needs, and experiences of caregivers ‘feeling invisible’ persist across studies. Emerging research indicates positive potential of contemplative self-care or stress-management approaches, such as mindfulness-based interventions (MBIs), to address the void of holistic care approaches. However, there is a lack of in-depth, qualitative understanding and conceptualisation of the process and effects of learning mindfulness in this setting. This qualitative study provides the first in-depth theoretical understanding of the experience of learning and using a mindfulness-based approach, whilst caring for a family member or friend at the end of life. Employing a constructivist grounded theory methodology (Charmaz 2006), semi-structured interviews were conducted with mindfulness facilitators (n=12) experienced in teaching mindfulness to informal palliative caregivers. In-depth interviews were also conducted with informal palliative caregivers (n=8) who had and used mindfulness in caregiving. Data was analysed concurrently with, and informed, data collection, progressing through the cycles of initial, focused and theoretical coding. Study findings have led to the development of a new grounded theory model: ‘The Experience of Learning and Using a Mindfulness-based Approach in End-of-life Caregiving: A Theoretical Model’. Findings identified multiple, interwoven benefits, including mindfulness as an empowering new form of respite and a way to shift caregiver reluctance to care for themselves. This study also challenges assumptions and practice regarding prescriptive, intensive approaches to mindfulness training advanced in other settings, advocating that there is no ‘one size fits all’ model. This conceptual understanding of the process, outcomes and challenges of learning mindfulness as an informal palliative caregiver can inform the development and evaluation of MBIs in this setting and has significant implications for practice and further research.

description: We investigate the roles of the relativistic effect on the speed of evolution of a quantum system coupled with amplitude damping channels.

For the damping strength $p_{τ_{c1}}\lesssim p_τ$, we observe a monotonic increasing behavior of QSLT, leads to slow down the quantum evolution of the damped system. In addition, we examine the roles of the relativistic effect on the speed limit time for a system coupled with the phase damping channels.

description: Black hole perturbation theory is useful for studying the stability of black holes and calculating ringdown gravitational waves after the collision of two black holes. Most previous calculations were carried out at the level of the field equations instead of the action. In this work, we compute the Einstein-Hilbert action to quadratic order in linear metric perturbations about a spherically symmetric vacuum background in Regge-Wheeler gauge. Using a 2+2 splitting of spacetime, we expand the metric perturbations into a sum over scalar, vector, and tensor spherical harmonics, and dimensionally reduce the action to two dimensions by integrating over the two sphere. We find that the axial perturbation degree of freedom is described by a two dimensional massive vector action, and that the polar perturbation degree of freedom is described by a two dimensional dilaton massive gravity action. Varying the dimensionally reduced actions, we rederive covariant and gauge-invariant master equations for the axial and polar degrees of freedom. Thus, the two dimensional massive vector and massive gravity actions we derive by dimensionally reducing the perturbed Einstein-Hilbert action describe the dynamics of a well studied physical system: the metric perturbations of a static black hole. The $2+2$ formalism we present can be generalized to $m+n$ dimensional spacetime splittings, which may be useful in more generic situations, such as expanding metric perturbations in higher dimensional gravity. We provide a self-contained presentation of $m+n$ formalism for vacuum spacetime splittings.

title: The bastard performer : an exploration of the actor/performer experience in a postdramatic and posthuman intermedial contemporary theatre and performance ecology
Creators: name: Jackson, CR
Publisher: name: University of Tasmania
Year: 2020

description: This practice-led research project explores the challenges and experiences faced by the contemporary actor/performer in rehearsal and performance, with specific reference to intermediality, multi-tasking, the intersection of acting/performance styles and interdisciplinary modalities. Over the last few decades, with the increasingly rapid integration of media technologies into performance, we have found ourselves at another catalytic point in performance history. We are racing to keep up with the possibilities and potentiality presented to us by technology, media and the power of new ‘linguistic’ relationships (Chatzichristodoulou and Crossley 2016) associated with them. The interaction between these different technologies and the performer onstage presents myriad opportunities and potentialities for aesthetic and artistic purposes – an intermedial exchange between the media provided in and of the performer themselves. The actor/performer’s ever evolving identity and practice is again thrust into a state of flux; forced to navigate and negotiate new hierarchical systems; creative terrain; modal vocabularies; and yet again the question: which image of their ‘selves’ is the dominant note in the polyphony of identity and (re)framing of the ‘performer’? They are largely left ‘in the woods’ to fend for themselves, marginalized (Hamilton 2008) and bastardised. This research project predominately regards the actor/performer within an intermedial and multimodal postdramatic performance setting. Referencing contemporary practitioners such as Katie Mitchell, Complicite, GobSquad and iv contemporary theorists such as Chiel Kattenbelt, Sarah Bay-Cheng, Robin Nelson, Margaret Hamilton, Andy Lavender, Brigit Wiens, Philip Zarrilli, and Tadashi Suzuki among others. It explores where the actor/performer sits within this emergent genre overrun with possibilities and hierarchical shifts? What is the experience of an actor/performer within these challenging intermedial works? How does an actor/performer ‘prepare’ for working in such complex conditions, in order to be an active participant in the creative conversations at play within such works? Ultimately, this research project examines how the performer interfaces with intermedial performance; and proposes a mode of practice in which the performer can embrace and be empowered to be an active creative entity in concert with the extension and augmentation of their ‘organic’ abilities through multimedia, technology and (re)mediation present in these platforms – through a posthuman approach to performance.

description: In Bayesian peer-to-peer decentralized data fusion, the underlying distributions held locally by autonomous agents are frequently assumed to be over the same set of variables (homogeneous). This requires each agent to process and communicate the full global joint distribution, and thus leads to high computation and communication costs irrespective of relevancy to specific local objectives. This work formulates and studies heterogeneous decentralized fusion problems, defined as the set of problems in which either the communicated or the processed distributions describe different, but overlapping, random states of interest that are subsets of a larger full global joint state. We exploit the conditional independence structure of such problems and provide a rigorous derivation of novel exact and approximate conditionally factorized heterogeneous fusion rules. We further develop a new version of the homogeneous Channel Filter algorithm to enable conservative heterogeneous fusion for smoothing and filtering scenarios in dynamic problems. Numerical examples show more than $99.5\%$ potential communication reduction for heterogeneous channel filter fusion, and a multi-target tracking simulation shows that these methods provide consistent estimates while remaining computationally scalable.

description: In the present article, we consistently develop the main issues of the Bloch vectors formalism for an arbitrary finite-dimensional quantum system. In the frame of this formalism, qudit states and their evolution in time, qudit observables and their expectations, entanglement and nonlocality, etc. are expressed in terms of the Bloch vectors -- the vectors in the Euclidean space $\mathbb{R}^{d^{2}-1}$ arising under decompositions of observables and states in different operator bases. Within this formalism, we specify for all $d\geq2$ the set of Bloch vectors of traceless qudit observables and describe its properties; also, find for the sets of the Bloch vectors of qudit states, pure and mixed, the new compact expressions in terms of the operator norms that explicitly reveal the general properties of these sets and have the unified form for all $d\geq2$. For the sets of the Bloch vectors of qudit states under the generalized Gell-Mann representation, these general properties cannot be analytically extracted from the known equivalent specifications of these sets via the system of algebraic equations. We derive the general equations describing the time evolution of the Bloch vector of a qudit state if a qudit system is isolated and if it is open and find for both cases the main properties of the Bloch vector evolution in time. For a pure bipartite state of a dimension $d_{1}\times d_{2}$, we quantify its entanglement in terms of the Bloch vectors for its reduced states. The introduced general formalism is important both for the theoretical analysis of quantum system properties and for quantum applications, in particular, for optimal quantum control, since, for systems where states are described by vectors in the Euclidean space, the methods of optimal control, analytical and numerical, are well developed.

description: The cover time of a Markov chain on a finite state space is the expected time until all states are visited. We show that if the cover time of a discrete-time Markov chain with rational transitions probabilities is bounded, then it is a rational number. The result is proved by relating the cover time of the original chain to the hitting time of a set in another higher dimensional chain. We also extend this result to the setting where $k\geq 1 $ independent copies of a Markov chain are run simultaneously on the same state space and the cover time is the expected time until each state has been visited by at least one copy of the chain.

description: We investigate the problem of characterizing the economic value of energy storage capacity to a wind power producer (WPP) that sells its energy in a conventional two-settlement electricity market. The WPP can offer a forward contract to supply power in the day-ahead market, subject to financial penalties for imbalances between the contracted power and the power that is delivered in real-time. We consider the setting in which the WPP has access to a co-located energy storage system, and can thus reshape its wind power production subject to its storage capacity constraints. Modeling wind power as a random process, we show that the problem of determining optimal forward contract offerings--given recourse with storage--is convex. We further establish that the maximum expected profit is concave and non-decreasing in the energy storage capacity, which reveals that the greatest marginal benefit from energy storage is derived from initial investment in small storage capacity. We provide a characterization of the marginal value of small energy storage capacity to the WPP. The formulae we derive shed light on the relationship between the value of storage and certain statistical measures of variability in the underlying wind power process.

title: Hydrodynamics of vertical surface-piercing cylinders
Creators: name: Potts, DA
Publisher: name: University of Tasmania

description: The fluid flow around a long, slender circular cylinder, either in air or water, is a practical circumstance that has been long-studied in the field of fluid dynamics (both aerodynamics and hydrodynamics). The advent of the offshore oil and gas industry after World War II, employed platforms, risers and pipelines formed from steel tubular sections. These were subject to hydrodynamic loading under waves and currents where the need to reliably characterise the fluid loading conditions provided significant impetus to this field of investigation on the fully submerged and vertical surface-piercing cylinders under uniform and oscillatory flow conditions. This thesis sets out a detailed investigation of the hydrodynamics of vertical surface-piercing cylinders. The aims of this thesis were to experimentally investigate: the effect of the end conditions on the Vortex-Induced Vibrations (VIV), the near field wake and the drag coefficient; the relationship between the depth of the ventilated pocket behind the cylinder with respect to the velocity and the Froude number; the typical hydrodynamic wake topology of a cylinder; and the finite aspect ratio at which the drag coefficient equals that of a typical fully submerged infinite cylinder. The findings derived within this thesis may be summarised as follows: 1. The submerged free end-tip condition does not influence the hydrodynamic wake properties of the bow wave nor the ventilated pocket depth. 2. The difference in results from the alternate end conditions affect the VIV by an approximate 25%, which may then be further influenced by the occurrence of VIV lock-in. 3. Although there is some disparity between the end conditions with respect to the drag coefficient, the overall difference may be deemed negligible. 4. A relationship may be developed between the ventilated pocket depth with respect to the velocity squared and the diameter. 5. A relationship between the non-dimensional bow wave height with respect to the velocity squared and the diameter may also be developed. 6. A finite vertical surface-piercing cylinder may be deemed to be infinite in length when the aspect ratio ≥ 47.

description: Considering a minimal number of assumptions and in the context of the timeless formalism, conditional probabilities are derived for subsequent measurements in the non-relativistic regime. Only unitary transformations are considered with detection processes described by generalized measurements (POVM). One-time conditional probabilities are unambiguously derived via the Gleason-Bush theorem, including for puzzling cases like the Wigner's friend scenario where their form underlines the relativity aspect of measurements. No paradoxical situations emerge and the roles of Wigner and Wigner can be seen by his friend as being in a superposition.

description: We show that neutrino spin and spin-flavor transitions involve nonvanishing geometric phases. The geometric character of neutrino spin rotation is explored by studying the neutrino spin trajectory in the projective Hilbert space representation and its relation to the geometric phase. Analytical expressions are derived for noncyclic geometric phases. Several calculations are performed for different cases of rotating and nonrotating magnetic fields in the context of solar neutrinos and neutrinos produced inside neutron stars. Also the effects of adiabaticity, critical magnetic fields and cross boundary effects in the case of neutrinos emanating out of neutron stars are examined.

Expletive negation and related problems
Creators: name: Ramat, Paolo
Publisher: name: Linguistic Typology at the Crossroads
Year: 2022

description: This paper makes two main claims: the presence of two or more negative elements in Negative Concord, Negative Comparison, and Expletive Negation basically rests upon the pragmatic need of intensifying the negative import of the sentence. Secondly, the paper aims at identifying a possible path of functional expansion that may account for the use of the Expletive Negation in the constructions under scrutiny. Expletive Negation is originally tied to the core concept of inequality comparison (x is more/has more y than z, where y refers to a state, a quality or property), as well as to temporal comparison (x before y)–where the second member is implicitly negated; it may then expand to other constructions such as Negative Concord and the construction of fear verbs.

description: Across a large range of scales, accreting sources show remarkably similar patterns of variability, most notably the log-normality of the luminosity distribution and the linear root-mean square (rms)-flux relationship. These results are often explained using the theory of propagating fluctuations in which fluctuations in the viscosity create perturbations in the accretion rate at all radii, propagate inwards and combine multiplicatively. While this idea has been extensively studied analytically in a linear regime, there has been relatively little numerical work investigating the non-linear behaviour. In this paper, we present a suite of stochastically driven 1-d $α$-disc simulations, exploring the behaviour of these discs. We find that the eponymous propagating fluctuations are present in all simulations across a wide range of model parameters, in contradiction to previous work. Of the model parameters, we find by far the most important to be the timescale on which the viscosity fluctuations occur. Physically, this timescale will depend on the underlying physical mechanism, thought to be the magnetorotational instability (MRI). We find a close relationship between this fluctuation timescale and the break frequency in the power spectral density (PSD) of the luminosity, a fact which could allow observational probes of the behaviour of the MRI dynamo. We report a fitting formula for the break frequency as a function of the fluctuation timescale, the disc thickness and the mass of the central object.

description: Scatter due to interaction of photons with the imaged object is a fundamental problem in X-ray Computed Tomography (CT). It manifests as various artifacts in the reconstruction, making its abatement or correction critical for image quality. Despite success in specific settings, hardware-based methods require modification in the hardware, or increase in the scan time or dose. This accounts for the great interest in software-based methods, including Monte-Carlo based scatter estimation, analytical-numerical, and kernel-based methods, with data-driven learning-based approaches demonstrated recently. In this work, two novel physics-inspired deep-learning-based methods, PhILSCAT and OV-PhILSCAT, are proposed. The methods estimate and correct for the scatter in the acquired projection measurements. Different from previous works, they incorporate both an initial reconstruction of the object of interest and the scatter-corrupted measurements related to it, and use a deep neural network architecture and cost function, both specifically tailored to the problem. Numerical experiments with data generated by Monte-Carlo simulations of the imaging of phantoms reveal consistent improvement over a recent purely projection-domain deep neural network scatter correction method.

description: We present the design and performance of an ultra-high vacuum (UHV) scanning tunneling microscope (STM) that uses adiabatic demagnetization of electron magnetic moments for controlling its operating temperature in the range between 30 mK and 1 K with the accuracy of up to 7 $μ$K. The time available for STM experiments at 50 mK is longer than 20 h, at 100 mK about 40 h. The single-shot adiabatic demagnetization refrigerator (ADR) can be regenerated automatically within 7 hours while keeping the STM temperature below 5 K. The whole setup is located in a vibrationally isolated, electromagnetically shielded laboratory with no mechanical pumping lines penetrating through its isolation walls. The 1K pot of the ADR cryostat can be operated silently for more than 20 days in a single-shot mode using a custom-built high-capacity cryopump. A high degree of vibrational decoupling together with the use of a specially-designed minimalistic STM head provides an outstanding mechanical stability, demonstrated by the tunneling current noise, STM imaging, and scanning tunneling spectroscopy measurements all performed on atomically clean Al(100) surface.

description: Misalignment between the camera frame and the operator frame is commonly seen in a teleoperated system and usually degrades the operation performance. The effects of such misalignment have not been fully investigated for eye-in-hand systems - systems that have the camera (eye) mounted to the end-effector (hand) to gain compactness in confined spaces such as in endoscopic surgery. This paper provides a systematic study on the effects of the camera frame misalignment in a teleoperated eye-in-hand robot and proposes a simple correction method in the view display. A simulation is designed to compare the effects of the misalignment under different conditions. Users are asked to move a rigid body from its initial position to the specified target position via teleoperation, with different levels of misalignment simulated. It is found that misalignment between the input motion and the output view is much more difficult to compensate by the operators when it is in the orthogonal direction (~40s) compared with the opposite direction (~20s). An experiment on a real concentric tube robot with an eye-in-hand configuration is also conducted. Users are asked to telemanipulate the robot to complete a pick-and-place task. Results show that with the correction enabled, there is a significant improvement in the operation performance in terms of completion time (mean 40.6%, median 38.6%), trajectory length (mean 34.3%, median 28.1%), difficulty (50.5%), unsteadiness (49.4%), and mental stress (60.9%).

description: Extending a classical theorem of Sperner, we characterize the integers $m$ such that there exists a maximal antichain of size $m$ in the Boolean lattice $B_n$, that is, the power set of $[n]:=\{1,2,\dots,n\}$, ordered by inclusion. As an important ingredient in the proof, we initiate the study of an extension of the Kruskal-Katona theorem which is of independent interest. For given positive integers $t$ and $k$, we ask which integers $s$ have the property that there exists a family $\mathcal F$ of $k$-sets with $\lvert\mathcal F\rvert=t$ such that the shadow of $\mathcal F$ has size $s$, where the shadow of $\mathcal F$ is the collection of $(k-1)$-sets that are contained in at least one member of $\mathcal F$. We provide a complete answer for $t\leqslant k+1$. Moreover, we prove that the largest integer which is not the shadow size of any family of $k$-sets is $\sqrt 2k^{3/2}+\sqrt[4]{8}k^{5/4}+O(k)$.
