description: Image vectorisation methods proposed in the past have not seen wide adoption due to performance, quality, controllability, and/or generality issues.We present a vectorisation method that uses mesh colours as a vector primitive for image vectorisation. We show that mesh colours have clear benefits for rendering performance and texture detail. Due to their flexibility, they also enable a simplified and more efficient generation of meshes of curved triangular patches, which are in our case constrained by our image feature extraction algorithm. The proposed method follows a standard pipeline where each step is efficient and controllable, leading to results that compare favourably with those from previous work. We show results over a variety of input images including photos, drawings, paintings, designs, and cartoons and also devise a user-guided vectorisation variant.

description: Progressive visualization allows users to examine intermediate results while they are further refined in the background. This makes them increasingly popular when dealing with large data and computationally expensive tasks. The characteristics of how preliminary visualizations evolve over time are crucial for efficient analysis; in particular unexpected disruptive changes between iterations can significantly hamper the user experience. This paper proposes a visualization framework to analyze the refinement behavior of progressive visualization. We particularly focus on sudden significant changes between the iterations, which we denote as popping artifacts, in reference to undesirable visual effects in the context of level of detail representations in computer graphics. Our visualization approach conveys where in image space and when during the refinement popping artifacts occur. It allows to compare across different runs of stochastic processes, and supports parameter studies for gaining further insights and tuning the algorithms under consideration. We demonstrate the application of our framework and its effectiveness via two diverse use cases with underlying stochastic processes: adaptive image space sampling, and the generation of grid layouts.

description: In this article we study the well-known strong lensing system SDSS J1004+4112. Not only does it host a large-separation lensed quasar with measured time-delay information, but several other lensed galaxies have been identified as well. A previously developed strong lens inversion procedure that is designed to handle a wide variety of constraints, is applied to this lensing system and compared to results reported in other works. Without the inclusion of a tentative central image of one of the galaxies as a constraint, we find that the model recovered by the other constraints indeed predicts an image at that location. An inversion which includes the central image provides tighter constraints on the shape of the central part of the mass map. The resulting model also predicts a central image of a second galaxy where indeed an object is visible in the available ACS images. We find masses of 2.5x10^13 M_O and 6.1x10^13 M_O within a radius of 60 kpc and 110 kpc respectively, confirming the results from other authors. The resulting mass map is compatible with an elliptical generalization of a projected NFW profile, with r_s = 58_{-13}^{+21} arcsec and c_vir = 3.91 +/- 0.74. The orientation of the elliptical NFW profile follows closely the orientation of the central cluster galaxy and the overall distribution of cluster members.

description: We derive the spectra of the cosmic X-ray background (CXB) and of the Galactic ridge X-ray emission (GRXE) in the ~20-200 keV range from the data of the IBIS instrument aboard the INTEGRAL satellite obtained during the four dedicated Earth-occultation observations of early 2006. We analyse the modulation of the IBIS/ISGRI detector counts induced by the passage of the Earth through the field of view of the instrument. Unlike previous studies, we do not fix the spectral shape of the various contributions, but model instead their spatial distribution and derive for each of them the expected modulation of the detector counts. The spectra of the diffuse emission components are obtained by fitting the normalizations of the model lightcurves to the observed modulation in different energy bins. The obtained CXB spectrum is consistent with the historic HEAO-1 results and falls slightly below the spectrum derived with Swift/BAT. A 10% higher normalization of the CXB cannot be completely excluded, but it would imply an unrealistically high albedo of the Earth. The derived spectrum of the GRXE confirms the presence of a minimum around 80 keV with improved statistics and yields an estimate of ~0.6 M_Sun for the average mass of white dwarfs in the Galaxy. The analysis also provides updated normalizations for the spectra of the Earth's albedo and the cosmic-ray induced atmospheric emission.

description: In this paper, we present a work-in-progress aimed at developing a pipeline for the fabrication of shapes reproducing digital models with a combination of standard LEGO bricks and 3D printed custom elements. The pipeline starts searching for the ideal alignment of the 3D model with the brick grid. It then employs a novel approach for shape "legolization" using a outside-in heuristic to limit critical configuration, and separates an external shell and an internal part. Finally, it exploits shape booleans to create the external custom parts to be 3D printed.

description: We use the adaptive time-dependent density matrix renormalization group method (t-DMRG) to study the nonequilibrium dynamics of a benchmark quantum impurity system which has a time-dependent Hamiltonian. This model is a resonant-level model, obtained by a mapping from a certain Ohmic spin-boson model describing the dissipative Landau-Zener transition. We map the resonant-level model onto a Wilson chain, then calculate the time-dependent occupation $n_d(t)$ of the resonant level. We compare t-DMRG results with exact results at zero temperature and find very good agreement. We also give a physical interpretation of the numerical results.

Stats, drugs and rock and roll : statistical applications to temporally autocorrelated substance use data
Creators: name: Humphries, Melissa
Publisher: name: University Of Tasmania
Year: 2023

description: The use of illicit drugs is an area of interest across a broad range of industries and fields including public policy, law enforcement and physical and mental health. Both the field of measuring drug use in the community and understanding its cognitive impacts are therefore the subject of constant research, development and innovation. This thesis examines statistical applications to temporally autocorrelated data in both the areas of drug use extent and cognitive impact. Specifically, sampling strategies for ascertaining drug use extent from waste water through the utilisation of patterns in weekly drug use is examined. This leads to a practical example of when representative sampling is cost effective enough to be a viable alternative to random sampling. The ability to ascertain cognitive impacts of drug use at the level of the individual is then explored. Analyses of empirical models of cognitive behaviour, that have been traditionally utilised to decompose behaviour, on psychological assessment tools the Iowa Gambling Task and the Balloon Analogue Risk Task are considered. We show that empirical models can lead to an inability to uniquely describe behaviour when considering individuals with possible cognitive impairments (those with extreme behaviours) and discuss the possibility of utilising mechanistic models of the data as a more reliable source of estimating behaviour in the extreme.

description: Prototyping is a widely used technique in the early stages of system design, and it is an essential part of a new product development process. During this phase, designers identify the main functionalities, concepts and contents of the system without creating a fully functional system. This paper aims to discuss the development of ProtoSketchAR, a tool enabling Augmented Reality (AR) prototyping by sketching. The application has different interaction modes, depending on the performed functionality. Basically, it is possible to create 2D/3D sketches to be placed in the real environment and to manipulate them. These functionalities allow the creation of virtual elements that can be used to prototype screens of AR applications. The application is web-based so that it can be run on any device with a compatible AR browser, regardless of the operating system used.

description: Point cloud registration is a fundamental task in 3D reconstruction and environment perception. We explore the performance of modern Deep Learning-based registration techniques, in particular Deep Global Registration (DGR) and Learning Multiview Registration (LMVR), on an outdoor real world data consisting of thousands of range maps of a building acquired by a Velodyne LIDAR mounted on a drone. We used these pairwise registration methods in a sequential pipeline to obtain an initial rough registration. The output of this pipeline can be further globally refined. This simple registration pipeline allow us to assess if these modern methods are able to deal with this low quality data. Our experiments demonstrated that, despite some design choices adopted to take into account the peculiarities of the data, more work is required to improve the results of the registration.

Differentiation of the chick oviduct in vitro
Creators: name: Vanderhorst, Elizabeth Wilhelmina Maria
Publisher: name: University of British Columbia
Year: 2011

description: Immature chick oviducts differentiate in vivo in response to daily injections of DES. This is indicated by increases in general oviduct protein nitrogen: DNA ratios and the production of immunologically precipitable ovalbumin. Three types of ovalbumin are produced in response to estrogen. These results indicate that ovalbumin free of phosphorus appears first in the oviduct tissue in response to DES. The appearance of phosphorus containing ovalbumin follows. Attempts were made to induce the in vitro differentiation of oviduct tissue under a variety of culture conditions. A standard culture media was supplemented with DES and serum (fetal calf, cockerel, laying hen, or chick serum) as well as serum from DES injected chicks. No changes were observed in the tissue histology nor in the production of the specific protein, ovalbumin, under the above conditions. Closely associated tissues such as kidneys, ovaries, mesentary or ureter tissue cultured with the oviduct tissue failed to elicite any detectible morphological and chemical changes in the latter. The addition of insulin or homogenized pituitaries from DES injected or non-injected chicks was ineffective as an inducer of differentiation in this system. Substituting 17 6-estradiol for DES as an inducer did not alter the results. Thus, with the exception of estrogen any factor(s) necessary for the in vivo differentiation of immature oviduct tissue remains unknown at this time.
On the Emergent Spectra of Hot Protoplanet Collision Afterglows

description: We explore the appearance of terrestrial planets in formation by studying the emergent spectra of hot molten protoplanets during their collisional formation. While such collisions are rare, the surfaces of these bodies may remain hot at temperatures of 1000-3000 K for up to millions of years during the epoch of their formation. These object are luminous enough in the thermal infrared to be observable with current and next generation optical/IR telescopes, provided that the atmosphere of the forming planet permits astronomers to observe brightness temperatures approaching that of the molten surface. Detectability of a collisional afterglow depends on properties of the planet's atmosphere -- primarily on the mass of the atmosphere. A planet with a thin atmosphere is more readily detected, because there is little atmosphere to obscure the hot surface. Paradoxically, a more massive atmosphere prevents one from easily seeing the hot surface, but also keeps the planet hot for a longer time. In terms of planetary mass, more massive planets are also easier to detect than smaller ones because of their larger emitting surface areas. We present preliminary calculations assuming a range of protoplanet masses (1-10 $M_\earth$), surface pressures (1-1000 bar), and atmospheric compositions, for molten planets with surface temperatures ranging from 1000 to 1800 K, in order to explore the diversity of emergent spectra that are detectable. While current 8- to 10-m class ground-based telescopes may detect hot protoplanets at wide orbital separations beyond 30 AU (if they exist), we will likely have to wait for next-generation extremely large telescopes or improved diffraction suppression techniques to find terrestrial planets in formation within several AU of their host stars.

description: We study how threshold model neurons transfer temporal and interneuronal input correlations to correlations of spikes. We find that the low common input regime is governed by firing rate dependent spike correlations which are sensitive to the detailed structure of input correlation functions. In the high common input regime the spike correlations are insensitive to the firing rate and exhibit a universal peak shape independent of input correlations. Rate heterogeneous pairs driven by common inputs in general exhibit asymmetric spike correlations. All predictions are confirmed in in vitro experiments with cortical neurons driven by synthesized fluctuating input currents.

Waterjet testing techniques for powering performance estimation using a single catamaran demihull
Creators: name: Z‚àö¬¿rcher, K
Publisher: name: University Of Tasmania
Year: 2023

description: A new series of highly efficient medium-speed wave-piercing catamarans is under development to reduce the environmental impact of fast sea transportation. They will operate at speeds where mutual interference between waves and increased resistance produces the characteristic hump in the ship's resistance curve. The challenge is the assessment of the effects of the change in operating conditions on the waterjet propulsion system. Waterjets are used for high-speed multihulls due to their high efficiency when operating at speeds beyond hump speed. However, they are generally not used for medium-speed applications due to the assumed decrease in efficiency at lower speed. A series of self-propulsion tests of a high-speed wave-piercing catamaran at medium-speeds was carried out to study the influence of the hydrodynamics at medium-speeds on the waterjet propulsors. The model tests were carried out using load varied (i.e. British method) self-propulsion testing in calm water. Due to size requirements of the model, a single demihull was utilised in close proximity to the side wall of the towing tank which acts as the plane of symmetry, reflecting waves generated by the demihull and therefore providing the correct blockage effects and wave interference for the non-existing second demihull. The results were validated using full-scale sea trials data for the vessel under consideration and for waterjet unit performance comparisons, a set of benchmark data was supplied by the waterjet unit manufacturer. The model tests showed that the propulsion unit at model scale is capable of reflecting the characteristics of the full scale waterjet. Furthermore, a new, thrust based extrapolation method was introduced and utilised with the results of the experimental testing carried out for the waterjet propulsion study. The results of this extrapolation were in correlation with the available full scale powering sea trials data.

description: We use computer simulations to study a model, first proposed by Wales [1], for the reversible and monodisperse self-assembly of simple icosahedral virus capsid structures. The success and efficiency of assembly as a function of thermodynamic and geometric factors can be qualitatively related to the potential energy landscape structure of the assembling system. Even though the model is strongly coarse-grained, it exhibits a number of features also observed in experiments, such as sigmoidal assembly dynamics, hysteresis in capsid formation and numerous kinetic traps. We also investigate the effect of macromolecular crowding on the assembly dynamics. Crowding agents generally reduce capsid yields at optimal conditions for non-crowded assembly, but may increase yields for parameter regimes away from the optimum. Finally, we generalize the model to a larger triangulation number T = 3, and observe more complex assembly dynamics than that seen for the original T = 1 model.

description: The 21-cm PDF (i.e., distribution of pixel brightness temperatures) is expected to be highly non-Gaussian during reionization and to provide important information on the distribution of density and ionization. We measure the 21-cm PDF as a function of redshift in a large simulation of cosmic reionization and propose a simple empirical fit. Guided by the simulated PDF, we then carry out a maximum likelihood analysis of the ability of upcoming experiments to measure the shape of the 21-cm PDF and derive from it the cosmic reionization history. Under the strongest assumptions, we find that upcoming experiments can measure the reionization history in the mid to late stages of reionization to 1-10% accuracy. Under a more flexible approach that allows for four free parameters at each redshift, a similar accuracy requires the lower noise levels of second-generation 21-cm experiments.

I offer it now for consumption and become a new animal. This thesis is divided into three units: poetry, translation and short story. The first section comprises a selection of earlier poems and the beginnings of a book tentatively titled Somewhere East. From random impressions in the early work, a more solid poetic analysis develops around the nation of Quebec. The central theme here is one of struggle. Unit two is a selection from four books by the French poet Guillevic, rendered here in English translation. From early work in Terraqué (Paris: Editions Gallimard, 1942) and Exécutoire (Paris: Editions Gallimard, 1948) to more recent poems in Carnac (Paris, Editions Gallimard, 1961) and Avec (Paris, Editions Gallimard, 1966), Guillevic's view remains simple and sympathetic, his poems the voice of one allied with the natural but oppressed by the reality of his social condition. The third unit contains three short fictions in prose which experiment with the fantasy which may be our own particular reality. These are lies about other "turkeys", about the tensions, silences and violence which drive them towards rebellion before they have nothing left at all.
The Category Theoretic Solution of Recursive Program Schemes

description: This paper provides a general account of the notion of recursive program schemes, studying both uninterpreted and interpreted solutions. It can be regarded as the category-theoretic version of the classical area of algebraic semantics. The overall assumptions needed are small indeed: working only in categories with "enough final coalgebras" we show how to formulate, solve, and study recursive program schemes. Our general theory is algebraic and so avoids using ordered, or metric structures. Our work generalizes the previous approaches which do use this extra structure by isolating the key concepts needed to study substitution in infinite trees, including second-order substitution. As special cases of our interpreted solutions we obtain the usual denotational semantics using complete partial orders, and the one using complete metric spaces. Our theory also encompasses implicitly defined objects which are not usually taken to be related to recursive program schemes. For example, the classical Cantor two-thirds set falls out as an interpreted solution (in our sense) of a recursive program scheme.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: In this paper we present soliton solutions of two coupled nonlinear Schodinger equations modulated in the bspace and time. The approach allows us to obatin solitons with large variety of solutions depending on the nonlinearity and the potential profiles. As examples we show three cases with soliton solution in such system, one of them with potential varying between repulsive and attractive behavior and the others with nonlinearity localized and delocalized, respectively.

description: The trend of digitizing analogue artefacts from cultural heritage collections to create cultural digital items remains ongoing. The user experience of Cultural Heritage Practitioners (CHP) should be understood in order to support academic efforts in producing practical contributions that benefit those working with cultural digital items. In this publication we follow a series of semi-structured interviews with 10 CHPs and supporting technical professionals who work with cultural digital items on a daily basis. We then code their responses for theme, analysing their thoughts and concerns regarding key topics connected to cultural digital items such as interactivity and the challenges of digitization within the culture heritage sector.

description: The following effects in the nearly forward ("soft") region of the LHC are proposed to be investigated: 1) At small |t| the fine structure of the cone (Pomeron) shouldbe scrutinized: a) a break of the cone near $t\approx - 0.1 ~ GeV$^2, due to the two-pion threshold, and required by t-channel unitarity, is expected, and b) possible small-period oscillations between $t=0$ and the dip region. 2) In measuring the elastic $pp$ scattering and total $pp$ cross section at the LHC, the experimentalists are urged to treat the total cross section $σ_t,$ the ratio $ρ$, the forward slope $B$ and the luminosity ${\cal L}$ as free arameters, and to publish model-independent results on ${dN/{dt}}.$ 3) Of extreme interest are the details of the expected diffraction minimum in the differential cross section. Its position, expected in the interval $0.4

description: The rapid technological advances in computing and computer graphics of the past three decades have in turn fueled the proliferation of the use of these technologies for Cultural Heritage. Formal educational courses for the application of computer graphics to Cultural Heritage are few and far between, and the courses that do exist tend to be targeted at archaeology students, with hardly any courses catering to computing or computer graphics students. To address this gap in education provision, we introduce a final year undergraduate course on ''CG and Animation for Cultural Heritage'', which provides students on technical and art & design computer graphics and animation courses with a broad introduction to the creation of Cultural Heritage applications of CG and animation techniques more commonly found in digital entertainment and visual effects. In this paper we describe this course and its curriculum and discuss its outcomes.
