description: According to the statistics, in Australia four children per week on average go to an emergency department or hospital after swallowing a button cell battery. Children under five face a greater risk and the majority of them cannot clearly descrbe the object they have swallowed. Therefore, in this thesis I aim to design a button cell scanner for doctors and families so that the swallowed object can be identified as soon as possible and surgery performed if needed. In this project, I did substantial research on the difference between button cells and coins which are similar in material and sharpness, as well as into feasible methods to solve the problem. Finally, prototypes are manufactured according to the feasible design and improvements. This document reports work that I have done this semester as well as problems that arose from the experiments.

description: We pre-register a web-based experiment in which we will test the efficacy of web-based eye-tracking in psycholinguistic research (focusing on the visual world paradigm). The participants will go through a battery of tasks (a fixation task, a smooth pursuit task, a lexical fixation task, a phonemic cohort task, and a verb bias task) over a teleconference call on Zoom. Within the same session, we will record their eye-movements using the participants’ own webcam, using the WebGazer.js algorithm, and by hand-annotating the participants’ eye movements on a video recording on Zoom. In a separate experiment, we will recruit participants to go through the task battery in a lab-based setting, while we will record their eye-movements using the webcam-methods described above, but also by using a professional-grade eye-tracking device. This experiment is pre-registered in the same OSF project (https://osf.io/sk8wu/)

Numerical modelling of the Sydney Basin using temperature dependent thermal conductivity measurements: thesis submitted on the 9th of October 2015

description: The thermal structure of continental crust is a critical factor for geothermal exploration, hydrocarbon maturation and crustal strength, and yet our understanding of it is limited by our incomplete knowledge of its geological structure and thermal properties. One of the most critical parameters in modelling upper crustal temperature is thermal conductivity, which itself exhibits strong temperature dependence. In this study, finite-element geothermal models of the Sydney Basin are generated through the use of deal.II finite element libraries. Basin geometry and structure is adapted from Danis, et al. (2011), which quantified the extent of Triassic sediment, Permian coal measures, Carboniferous volcanics and Basement thickness. We find that temperature-dependent thermal conductivity result in lower lateral variation in temperature, compared to constant thermal conductivity models. However, the average temperatures at depth are significantly higher when temperature-dependent thermal conductivity effects are included. A number of regions within the Sydney Basin demonstrate temperatures above 150⁰C at depths of less than 2000m in these models, for instance NW of Singleton exhibits a strong thermal anomaly, demonstrating the potential for geothermal prospectivity of the region from experimentally-constrained thermal parameters. Future work will address the repeatability and application of this type of thermal model in areas of varying geology and stratigraphy.

description: The so-called unidentified infrared emission (UIE) features at 3.3, 6.2, 7.7, 8.6, and 11.3 $μ$m ubiquitously seen in a wide variety of astrophysical regions are generally attributed to polycyclic aromatic hydrocarbon (PAH) molecules. Astronomical PAHs may have an aliphatic component as revealed by the detection in many UIE sources of the aliphatic C-H stretching feature at 3.4 $μ$m. The ratio of the observed intensity of the 3.4 $μ$m feature to that of the 3.3 $μ$m aromatic C-H feature allows one to estimate the aliphatic fraction of the UIE carriers. This requires the knowledge of the intrinsic oscillator strengths of the 3.3 $μ$m aromatic C-H stretch ($A_{3.3}$) and the 3.4 $μ$m aliphatic C-H stretch ($A_{3.4}$). Lacking experimental data on $A_{3.3}$ and $A_{3.4}$ for the UIE candidate materials, one often has to rely on quantum-chemical computations. Although the second-order Moller-Plesset (MP2) perturbation theory with a large basis set is more accurate than the B3LYP density functional theory, MP2 is computationally very demanding and impractical for large molecules. Based on methylated PAHs, we show here that, by scaling the band strengths computed at an inexpensive level (e.g., B3LYP/6-31G*) we are able to obtain band strengths as accurate as that computed at far more expensive levels (e.g., MP2/6-311+G(3df,3pd)).

description: We consider the inclusion process on the complete graph with vanishing diffusivity, which leads to condensation of particles in the thermodynamic limit. Describing particle configurations in terms of size-biased and appropriately scaled empirical measures of mass distribution, we establish convergence in law of the inclusion process to a measure-valued Markov process on the space of probability measures. In the case where the diffusivity vanishes like the inverse of the system size, the derived scaling limit is equivalent to the well known Poisson-Dirichlet diffusion, offering an alternative viewpoint on these well-established dynamics. Moreover, our approach covers all scaling regimes of the system parameters and yields a natural extension of the Poisson-Dirichlet diffusion to infinite mutation rate. We also discuss in detail connections to known results on related Fleming-Viot processes.

Late Triassic volcanism of the Ipswich Basin
Creators: name: Roach, Andrew Ferguson
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: The Ipswich Basin, an extensive Late Triassic basin that straddles the Queensland-New South Wales border in eastern Australia, contains a basal sequence of felsic and mafic volcanic rocks, which, together with the Agnes Water Volcanics, Aranbanga Beds, Mount Byron Volcanics, Muncon Volcanics, North Arm Volcanics, and numerous plutons, form a major igneous province. Volcanism in the Ipswich Basin was manifested in an older mafic- dominated (in parts bi-modal) belt on the west, and a younger, silicic belt to the east. An early phase of calc-alkaline rhyolitic lava in the subsurface is succeeded by exposed basaltic andesite lava flows and air-fall tuffs of the Sugars Basalt and Weir Basalt. Commencing in the westernmost sections, coarse clastic sedimentary rocks were deposited in fans along the West Ipswich Fault. Farther east near Brisbane and south to Mount Warning, extensive rhyolitic volcanism generated the ignimbrites of the Brisbane Tuff, the rhyo-dacitic air-fall tuffs and ignimbrites of the Mount Crosby Formation and Hector Huff, the rhyolitic lavas and pyroclastic rocks of the Chillingham Volcanics, and the isolated exposures of rhyolitic lavas on Moreton and Stradbroke Islands. The Brisbane Tuff is a valley-fill ignimbrite, with minor air-fall tuffs and ground surges, and at Carindale an ignimbrite outflow sheet. The Brisbane Tuff is a single cooling unit of flows continuously emplaced from a single vent. The coeval Chillingham Volcanics extend southward from Brisbane in an 80 km long belt of silicic volcanism. The Chillingham Volcanics follow a cycle of precursory pyroclastic eruptions and subsequent fissure-type lava effusion. In the south and centre, an earlier cycle of pyroclastic rock eruption and lava emplacement in domes also occurs. The northerly strike of vertically oriented zones of flow banding, thought to reflect feeder dykes, parallels the regional strike so the eruptive fissures may be related to deep basin-forming structures. -- The chemistry of the Ipswich Basin mafic rocks differs from that of mafic rocks from volcanic-arc or within-plate settings, though sharing features of both. I interpret the "mixed" signature as reflecting the tectonic environment into which the mafic rocks were erupted, namely an area of back-arc extension. Rocks with chemical characteristics similar to the Ipswich Basin mafic rocks are present in the early stages of rifting in the Basin and Range Province of the western United States, the South Shetland Islands, and parts of the Central Andes. Geochemistry is consistent with the postulated tectonic setting of the Ipswich Basin in an area of back-arc extension associated with strike-slip faulting. -- Volcanism ceased later in the Late Triassic during the eastward migration of the heat source, and was followed by deposition of the thick coal measures around Ipswich.

Bounded solutions for non-parametric mean curvature problems with nonlinear terms

description: In this paper we prove existence of nonnegative bounded solutions for the non-autonomous prescribed mean curvature problem in non-parametric form on an open bounded domain $Ω$ of $\mathbb{R}^N$. The mean curvature, that depends on the location of the solution $u$ itself, is asked to be of the form $f(x)h(u)$, where $f$ is a nonnegative function in $L^{N,\infty}(Ω)$ and $h:\mathbb{R}^+\mapsto \mathbb{R}^+$ is merely continuous and possibly unbounded near zero. As a preparatory tool for our analysis we propose a purely PDE approach to the prescribed mean curvature problem not depending on the solution, i.e. $h\equiv 1$. This part, which has its own independent interest, aims to represent a modern and up-to-date account on the subject. Uniqueness is also handled in presence of a decreasing nonlinearity. The sharpness of the results is highlighted by mean of explicit examples.

General Model for Light curves of Chromospherically Active Binary Stars

description: The starspots on the surface of many chromospherically active binary stars concentrate on long--lived active longitudes separated by 180 degrees. The activity shifts between these two longitudes, the "flip-flop" events, have been observed in single stars like FK Comae and binary stars like $σ$ Geminorum. Recently, interferometry has revealed that ellipticity may at least partly explain the "flip-flop" events in $σ$ Geminorum. This idea was supported by the double peaked shape of the long--term mean light curve of this star. Here, we show that the long--term mean light curves of fourteen chromospherically active binaries follow a general model which explains the connection betweenm orbital motion, starspot distribution changes, ellipticity and \flip ~events. Surface differential rotation is probably weak in these stars, because the interference of two constant period waves may explain the observed light curve changes. These two constant periods are the active longitude period $(P_{\mathrm{act}})$ and the orbital period $(P_{\mathrm{orb}})$. We also show how to apply the same model to single stars, where only the value of $P_{\mathrm{act}}$ is known. Finally, we present a tentative interference hypothesis about the origin of magnetic fields in all spectral types of stars.

description: In this paper, we derive a lubrication model to describe the non-stationary free liquid film that is created when a vertical frame is pulled out of a liquid reservoir at a given velocity. We here focus on the case of a pure liquid, corresponding to a stress-free boundary condition at the liquid/air interfaces of the film, and thus employ an essentially extensional description of the flow. Taking into account van der Waals interactions between the interfaces, we observe that film rupture is well-defined in time as well as in space, which allows us to compute the critical thickness and the film height at the moment of rupture. The theoretical predictions of the model turn out to be in quantitative agreement with experimental measurements of the break-up height of silicone oil films in a wide range of pulling velocities and supporting fiber diameters.

description: Let $G$ be the semidirect product $N \rtimes \mathbb{R}$, where $N$ is a stratified Lie group and $\mathbb{R}$ acts on $N$ via automorphic dilations. Homogeneous left-invariant sub-Laplacians on $N$ and $\mathbb{R}$ can be lifted to $G$, and their sum $Δ$ is a left-invariant sub-Laplacian on $G$. In previous joint work of Ottazzi, Vallarino and the first-named author, a spectral multiplier theorem of Mihlin--Hörmander type was proved for $Δ$, showing that an operator of the form $F(Δ)$ is of weak type $(1,1)$ and bounded on $L^p(G)$ for all $p \in (1,\infty)$ provided $F$ satisfies a scale-invariant smoothness condition of order $s > (Q+1)/2$, where $Q$ is the homogeneous dimension of $N$. Here we show that, if $N$ is a group of Heisenberg type, or more generally a direct product of Métivier and abelian groups, then the smoothness condition can be pushed down to the sharp threshold $s>(d+1)/2$, where $d$ is the topological dimension of $N$. The proof is based on lifting to $G$ weighted Plancherel estimates on $N$ and exploits a relation between the functional calculi for $Δ$ and analogous operators on semidirect extensions of Bessel--Kingman hypergroups.

Counterfactuals and counterparts: defending a neo-Humean theory of causation
Creators: name: McDonnell, Neil
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Whether there exist causal relations between guns firing and people dying, between pedals pressed and cars accelerating, or between carbon dioxide emissions and global warming, is typically taken to be a mind-independent, objective, matter of fact. However, recent contributions to the literature on causation, in particular theories of contrastive causation and causal modelling, have undermined this central causal platitude by relativising causal facts to models or to interests. This thesis flies against the prevailing wind by arguing that we must pay greater attention to which elements of our causal talk vary with context and which elements track genuine features of the world around us. I will argue that once these elements are teased apart we will be in a position to better understand some of the most persistent problems in the philosophy of causation: pre-emption cases, absence causation, failures of transitivity and overdetermination. The result is a naturalist account of causation, concordant with the contextual variability we find in our ordinary causal talk, and parsimonious with respect to the theoretical entities posited.

description: The orbital susceptibility for graphene is calculated exactly up to the first order with respect to the overlap integrals between neighboring atomic orbitals. The general and rigorous theory of orbital susceptibility developed in the preceding paper is applied to a model for graphene as a typical two-band model. It is found that there are contributions from interband, Fermi surface, and occupied states in addition to the Landau--Peierls orbital susceptibility. The relative phase between the atomic orbitals on the two sublattices related to the chirality of Dirac cones plays an important role. It is shown that there are some additional contributions to the orbital susceptibility that are not included in the previous calculations using the Peierls phase in the tight-binding model for graphene. The physical origin of this difference is clarified in terms of the corrections to the Peierls phase.

The practical definite defectives (DD) detection algorithm is known to be optimal for $θ\geq 1/2$. We give a new upper bound on the rate of DD, showing that DD is strictly suboptimal for $θ< 0.41$. We also show that the SCOMP algorithm and algorithms based on linear programming achieve a rate at least as high as DD, so in particular are also optimal for $θ\geq 1/2$.

description: Robots operating alongside humans often encounter unfamiliar environments that make autonomous task completion challenging. Though improving models and increasing dataset size can enhance a robot's performance in unseen environments, data collection and model refinement may be impractical in every environment. Approaches that utilize human demonstrations through manual operation can aid in refinement and generalization, but often require significant data collection efforts to generate enough demonstration data to achieve satisfactory task performance. Interactive approaches allow for humans to provide correction to robot action in real time, but intervention policies are often based on explicit factors related to state and task understanding that may be difficult to generalize. Addressing these challenges, we train a lightweight interaction policy that allows robots to decide when to proceed autonomously or request expert assistance at estimated times of uncertainty. An implicit estimate of uncertainty is learned via evaluating the feature extraction capabilities of the robot's visual navigation policy. By incorporating part-time human interaction, robots recover quickly from their mistakes, significantly improving the odds of task completion. Incorporating part-time interaction yields an increase in success of 0.38 with only a 0.3 expert interaction rate within the Habitat simulation environment using a simulated human expert. We further show success transferring this approach to a new domain with a real human expert, improving success from less than 0.1 with an autonomous agent to 0.92 with a 0.23 human interaction rate. This approach provides a practical means for robots to interact and learn from humans in real-world settings.

description: We present spectral line mapping observations toward four massive star-forming regions (Cepheus A, DR21S, S76E and G34.26+0.15), with the IRAM 30 meter telescope at 2 mm and 3 mm bands. Totally 396 spectral lines from 51 molecules, one helium recombination line, ten hydrogen recombination lines, and 16 unidentified lines were detected in these four sources. An emission line of nitrosyl cyanide (ONCN, 14$_{0,14}$-13$_{0,13}$) was detected in G34.26+0.15, as first detection in massive star-forming regions. We found that the $c$-C$_{3}$H$_{2}$ and NH$_{2}$D show enhancement in shocked regions as suggested by evidences of SiO and/or SO emission. Column density and rotational temperature of CH$_{3}$CN were estimated with the rotational diagram method for all four sources. Isotope abundance ratios of $^{12}$C/$^{13}$C were derived using HC$_{3}$N and its $^{13}$C isotopologue, which were around 40 in all four massive star-forming regions and slightly lower than the local interstellar value ($\sim$65). $^{14}$N/$^{15}$N and $^{16}$O/$^{18}$O abundance ratios in these sources were also derived using double isotopic method, which were slightly lower than that in local interstellar medium. Except for Cep A, $^{33}$S/$^{34}$S ratio in the other three targets were derived, which were similar to that in the local interstellar medium. The column density ratios of N(DCN)/N(HCN) and N(DCO$^{+}$)/N(HCO$^{+}$) in these sources were more than two orders of magnitude higher than the elemental [D]/[H] ratio, which is 1.5$\times$10$ ^{-5}$. Our results show the later stage sources, G34.26+0.15 in particular, present more molecular species than earlier stage ones. Evidence of shock activity is seen in all stages studied.

During Run 2 of the LHC, a luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$ was routinely achieved at the start of fills, twice the design luminosity. For Run 3, accelerator improvements, notably luminosity levelling, allow sustained running at an instantaneous luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$, with an average of up to 60 interactions per bunch crossing. The ATLAS detector has been upgraded to recover Run 1 single-lepton trigger thresholds while operating comfortably under Run 3 sustained pileup conditions. A fourth pixel layer 3.3 cm from the beam axis was added before Run 2 to improve vertex reconstruction and $b$-tagging performance. New Liquid Argon Calorimeter digital trigger electronics, with corresponding upgrades to the Trigger and Data Acquisition system, take advantage of a factor of 10 finer granularity to improve triggering on electrons, photons, taus, and hadronic signatures through increased pileup rejection. The inner muon endcap wheels were replaced by New Small Wheels with Micromegas and small-strip Thin Gap Chamber detectors, providing both precision tracking and Level-1 Muon trigger functionality. Tile Calorimeter scintillation counters were added to improve electron energy resolution and background rejection. Upgrades to Minimum Bias Trigger Scintillators and Forward Detectors improve luminosity monitoring and enable total proton-proton cross section, diffractive physics, and heavy ion measurements. These upgrades are all compatible with operation in the much harsher environment anticipated after the High-Luminosity upgrade of the LHC and are the first steps towards preparing ATLAS for the High-Luminosity upgrade of the LHC. This paper describes the Run 3 configuration of the ATLAS detector.

The role of the independent non-executive director in Australia

description: Company directors have been in existence for more than four hundred years. In the past, they were considered to be a necessary part of corporate existence, and were usually appointed to a board by the CEO or chairman. However, they were usually mates from the 'boys club' and gained their position from whom they knew, and not from what they were capable of contributing. The appointment of independent directors became more normal, as shareholders looked for a way to wrest control back from management. But what independent directors really do and why they are there is not widely understood. A review of the literature relative to independent directors has identified a gap in the knowledge. This gap is the role of the independent director when considered from a commercial aspect; that is, those who observe or write about independent directors. --This thesis has attempted to generate a theory of the role of the independent director through a review of the literature and a subsequent series of interviews. Grounded theory was the chosen methodology for analysing the data and formulating a theory of the role because it allows the researcher to ground the theory in the data instead of establishing a hypothesis and testing it. --The resulting theory is more complex than it first appears. It was found that the primary role of the independent director is to improve the performance of the board and the company. This role is impacted by a number of factors, the two most influential being the information that is available to the independent directors, and the position of the company. This second factor is defined as the size of the company, where it is in its life cycle, and whether it is experiencing any significant change. --These findings enable a number of recommendations to be made to improve policy and practice, recognising the impact of information and company position on the ability of independent directors to contribute positively. It also raises several areas of further study to continue to refine the understanding of the role of the independent nonexecutive director in Australia. These include, among others, investigating the role from other viewpoints such as the board chair or company secretary, or researching the link between company position and information available to independent directors.

description: A domótica pode ser entendida como o controlo automatizado das instalações técnicas existentes num edifício. [...] Como hoje em dia, aspetos como a segurança, eficiência energética, conforto e comunicação são cada vez mais uma exigência dos proprietários/utilizadores dos edifícios, não faz sentido continuar a abordar a execução de instalações elétricas do tipo convencional, sistemas de AVAC, alarmes e outros, sem que estes comuniquem entre si.

description: Foi de forma natural que o aproveitamento do recurso eólico evoluiu dos tradicionais parques em terra (onshore) para locais offshore. Se por um lado os melhores locais para instalação em terra começam a escassear, a grande disponibilidade de recurso offshore permite a disponibilidade de áreas muito elevadas para a sua exploração. Os ventos mais fortes, no mar, associados a uma rugosidade de classe zero criam condições ideais para a instalação de geradores eólicos de potência elevada tornando assim possível uma maior produtividade, que pode compensar os inerentes custos de instalação e de operação mais elevados. No entanto existem alguns desafios que necessitam de ser mais investigados e que estão a ser alvo de investimento, tais como as torres, os sistemas de fixação e a instalação da cablagem.

description: The Infrared Spectrograph (IRS) on the {\em Spitzer Space Telescope} observed nearly 800 point sources in the Large Magellanic Cloud (LMC), taking over 1,000 spectra. 197 of these targets were observed as part of the Sage-Spec Spitzer Legacy program; the remainder are from a variety of different calibration, guaranteed time and open time projects. We classify these point sources into types according to their infrared spectral features, continuum and spectral energy distribution shape, bolometric luminosity, cluster membership, and variability information, using a decision-tree classification method. We then refine the classification using supplementary information from the astrophysical literature. We find that our IRS sample is comprised substantially of YSO and H\,{\sc ii} regions, post-Main Sequence low-mass stars: (post-)AGB stars and planetary nebulae and massive stars including several rare evolutionary types. Two supernova remnants, a nova and several background galaxies were also observed. We use these classifications to improve our understanding of the stellar populations in the Large Magellanic Cloud, study the composition and characteristics of dust species in a variety of LMC objects, and to verify the photometric classification methods used by mid-IR surveys. We discover that some widely-used catalogues of objects contain considerable contamination and others are missing sources in our sample.

description: In this contribution I will review some of the researches that are currently being pursued in Padova (mainly within the In:Theory and Strength projects), focusing on the interdisciplinary applications of nuclear theory to several other branches of physics, with the aim of contributing to show the centrality of nuclear theory in the Italian scientific scenario and the prominence of this fertile field in fostering new physics. In particular, I will talk about: i) the recent solution of the long-standing "electron screening puzzle" that settles a fundamental controversy in nuclear astrophysics between the outcome of lab experiments on earth and nuclear reactions happening in stars; the application of algebraic methods to very diverse systems such as: ii) the supramolecular complex H2@C60, i.e. a diatomic hydrogen molecule caged in a fullerene and iii) to the spectrum of hypernuclei, i.e. systems made of a Lambda particles trapped in (heavy) nuclei.

Star-forming filament models

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: New models of star-forming filamentary clouds are presented, to quantify their properties and to predict their evolution. These 2D axisymmetric models describe filaments having no core, one low-mass core, and one cluster-forming core. They are based on Plummer-like cylinders and spheroids, bounded by a constant-density surface of finite extent. In contrast to 1D Plummer-like models, they have specific values of length and mass, they approximate observed column density maps, and their distributions of column density (N-pdfs) are pole-free. Each model can estimate the star-forming potential of a core-filament system, by identifying the zone of gas dense enough to form low-mass stars, and by counting the number of enclosed thermal Jeans masses. This analysis suggests that the Musca Center filament may be near the start of its star-forming life, with enough dense gas to make its first ~3 protostars, while the Coronet filament is near the midpoint of its star formation, with enough dense gas to add ~ 8 protostars to its ~20 known stars. In contrast L43 appears near the end of its star-forming life, since it lacks enough dense gas to add any new protostars to the 2 YSOs already known.

description: Selecting an appropriate method when describing the motion of the knee in 3D space can be challenging as there is no universal or standard definition currently utilised in biomechanical studies. The Joint Coordinate System (JCS), first proposed by Grood and Suntay, is widely used by various authors to define the relative position between two rigid bodies as the definitions when establishing the system is easily comprehended. Throughout this thesis, a program will be developed in Matlab to enable the automation of the joint coordinate system on the femur and tibia by defining the anatomical landmarks. The JCS will be redefined and used as a basis to implement a slightly different coordinate system. This automated program will allow simplicity when manipulating the orientation and will enable the data to be presented in different clinical systems.
