description: Commonly used methods to decompose E- and B-modes in cosmic shear, namely the aperture mass dispersion and the E/B-mode shear correlation function, suffer from incomplete knowledge of the two-point correlation function (2PCF) on very small and/or very large scales. The ring statistics, the most recently developed cosmic shear measure, improves on this issue and is able to decompose E- and B-modes using a 2PCF measured on a finite interval. First, we improve on the ring statistics' filter function with respect to the signal-to-noise ratio. Second, we examine the ability of the ring statistics to constrain cosmology and compare the results to cosmological constraints obtained with the aperture mass dispersion. Third, we use the ring statistics to measure a cosmic shear signal from CFHTLS (Canada-France-Hawaii Telescope Legacy Survey) data. We consider a scale-dependent filter function for the ring statistics which improves its signal-to-noise ratio. In addition, we show that there exist filter functions which decompose E- and B-modes using a finite range of 2PCFs (EB-statistics) and have higher S/N ratio than the ring statistics. However, we find that data points of the latter are significantly less correlated than data points of the aperture mass dispersion and the EB-statistics. As a consequence the ring statistics is an ideal tool to identify remaining systematics accurately as a function of angular scale. We use the 2PCF of the latest CFHTLS analysis and therefrom calculate the ring statistics and its error bars.

The targum (1942:Apr. 1 - 1942:Apr. 29)
Creators: name: No Name Supplied

Year: 1942

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We determine the minimal density of triangles in a tripartite graph with prescribed edge densities. This extends a previous result of Bondy, Shen, Thomassé and Thomassen characterizing those edge densities guaranteeing the existence of a triangle in a tripartite graph. To be precise we show that a suitably weighted copy of the graph formed by deleting a certain 9-cycle from $K_{3,3,3}$ has minimal triangle density among all weighted tripartite graphs with prescribed edge densities.

description: AIMS: Nova Cyg 2006 has been intensively observed throughout its full outburst. We investigate the energetics and evolution of the central source and of the expanding ejecta, their chemical abundances and ionization structure, and the formation of dust. METHOD: We recorded low, medium, and/or high-resolution spectra (calibrated into accurate absolute fluxes) on 39 nights, along with 2353 photometric UBVRcIc measures on 313 nights, and complemented them with IR data from the literature. RESULTS: The nova displayed initially the normal photometric and spectroscopic evolution of a fast nova of the FeII-type. Pre-maximum, principal, diffuse-enhanced, and Orion absorption systems developed in a normal way. After the initial outburst, the nova progressively slowed its fading pace until the decline reversed and a second maximum was reached (eight months later), accompanied by large spectroscopic changes. Following the rapid decline from second maximum, the nova finally entered the nebular phase and formed optically thin dust. We computed the amount of formed dust and performed a photo-ionization analysis of the emission-line spectrum during the nebular phase, which showed a strong enrichment of the ejecta in nitrogen and oxygen, and none in neon, in agreement with theoretical predictions for the estimated 1.0 Msun white dwarf in Nova Cyg 2006. The similarities with the poorly investigated V1493 Nova Aql 1999a are discussed.

Interpersonal cognitive problem-solving with chronic schizophrenics
Creators: name: Axford, Sharon
Publisher: name: University Of Tasmania
Year: 2023

description: This study evaluated the effects of an interpersonal cognitive problem-solving programme on chronic schizophrenic inpatients, to see whether it was more effective in increasing problem-solving skills and adaptive functioning on the ward than medication alone or medication and group meetings. Thirty chronic schizophrenic inpatients were matched in trios for age, education, time since first diagnosis and problem-solving skills. Each member of a trio was allocated to either the problem-solving group, the group control for attention and structure or the no treatment group. The experimental and control group met each week for 45 minutes for between 6 and 9 weeks. The experimental group were trained in the 4 stages of problem-solving: recognising problems, producing alternative solutions, being aware of the consequences of their actions and choosing solutions to interpersonal problems. Problem-solving measures were taken one week before, one week and 2 months after the intervention. Also nurses on the subjects' wards completed NOSIE-30s before and after the programme and at follow-up, as a measure of how much if at all subjects' behaviour changed on the ward. ‚Äö No significant difference was found between the groups on any of the measures. The experimental group's problem-solving skills did not improve significantly nor did their behaviour on the ward. Comparision with similar studies are made and improvements suggested. Recommendations are made for interpersonal problemsolving's role in the treatment of chronic schizophrenics.
Modifications in presentation of the farnsworth- munsell 100-hue test for use in the elementary schools

Year: 2011

description: Because of the increasing use of colour as a primary cue developing concept and as a contextual cue, this study was conducted to modify presentations of the 100-Hue Test for colour discrimination in order to make it a useable instrument for screening the elementary school child who might have difficulties with colour discrimination though he is not a colour defective, which could handicap his school performance. The subjects were 124 boys, aged 12 years. They were divided into four equivalent groups in relation to I.Q. The Ss were Vancouver, B.C. elementary public school children. The Dvorine Pseudo-Isochromatic plates were shown to each subject as a means of establishing rapport and quickly identifying colour defectives so that they could be excluded from the sample - 4 defectives were found who had congenital anomalies. This percentage of 4.9 was lower than the commonly reported 8.1% for the male population. Group 1 were read the standard adult instructions from the Farnsworth-Munsell 100-Hue manual, before being asked to complete the test. Group 2 were read the standard adult instructions from the Farnsworth manual for the Panel D-15 (Dichotomous Test for Colour Blindness), before completing this test plus the adult instructions from the 100-Hue manual, before completing the latter test. Group 3 were read a standardized set of modified instructions which were created for this study. Group 4 were read the same set of modified instructions with the addition of the use of the Panel D-15 as part of the instructions. Statistical analysis of the mean error scores for the 4 groups revealed, as hypothesized, statistically different means between the groups using the modified and those using the standard instructions. Group 3, using modified instructions without the inclusion of the Panel D-15 performed best, functioning as well with these instructions as do adult subjects. The results indicate that 12 year olds can function significantly better on the 100-Hue test with modified instruction than other studies with other populations of children, using other types of presentations have indicated.

description: We report on XMM-Newton and optical results for 6 cataclysmic variables that were selected from Sloan Digital Sky Survey spectra because they showed strong HeII emission lines, indicative of being candidates for containing white dwarfs with strong magnetic fields. While high X-ray background rates prevented optimum results, we are able to confirm SDSSJ233325.92+152222.1 as an intermediate polar from its strong pulse signature at 21 min and its obscured hard X-ray spectrum. Ground-based circular polarization and photometric observations were also able to confirm SDSSJ142256.31-022108.1 as a polar with a period near 4 hr. Photometry of SDSSJ083751.00+383012.5 and SDSSJ093214.82+495054.7 solidifies the orbital period of the former as 3.18 hrs and confirms the latter as a high inclination system with deep eclipses.

description: We calculate the entanglement-assisted and unassisted channel capacities of an exactly solvable spin star system, which models the quantum dephasing channel. The capacities for this non-Markovian model exhibit a strong dependence on the coupling strengths of the bath spins with the system, the bath temperature, and the number of bath spins. For equal couplings and bath frequencies, the channel becomes periodically noiseless.

description: Quantum dots defined in carbon nanotubes are a platform for both basic scientific studies and research into new device applications. In particular, they have unique properties that make them attractive for studying the coherent properties of single electron spins. To perform such experiments it is necessary to confine a single electron in a quantum dot with highly tunable barriers, but disorder has until now prevented tunable nanotube-based quantum-dot devices from reaching the single-electron regime. Here, we use local gate voltages applied to an ultra-clean suspended nanotube to confine a single electron in both a single quantum dot and, for the first time, in a tunable double quantum dot. This tunability is limited by a novel type of tunnelling that is analogous to that in the Klein paradox of relativistic quantum mechanics.

description: Constrained Optimum Path (COP) problems appear in many real-life applications, especially on communication networks. Some of these problems have been considered and solved by specific techniques which are usually difficult to extend. In this paper, we introduce a novel local search modeling for solving some COPs by local search. The modeling features the compositionality, modularity, reuse and strengthens the benefits of Constrained-Based Local Search. We also apply the modeling to the edge-disjoint paths problem (EDP). We show that side constraints can easily be added in the model. Computational results show the significance of the approach.
Generic Mechanism of Emergence of Amyloid Protofilaments from Disordered Oligomeric aggregates

description: The presence of oligomeric aggregates, which is often observed during the process of amyloid formation, has recently attracted much attention since it has been associated with neurodegenerative conditions such as Alzheimer's and Parkinson's diseases. We provide a description of a sequence-indepedent mechanism by which polypeptide chains aggregate by forming metastable oligomeric intermediate states prior to converting into fibrillar structures. Our results illustrate how the formation of ordered arrays of hydrogen bonds drives the formation of beta-sheets within the disordered oligomeric aggregates that form early under the effect of hydrophobic forces. Initially individual beta-sheets form with random orientations, which subsequently tend to align into protofilaments as their lengths increases. Our results suggest that amyloid aggregation represents an example of the Ostwald step rule of first order phase transitions by showing that ordered cross-beta structures emerge preferentially from disordered compact dynamical intermediate assemblies.

description: This talk presents a lattice study of spontaneous chiral symmetry breaking performed by the JLQCD and TWQCD collaborations with dynamical overlap fermions. Our lattice configurations are generated in a fixed topological sector. Since finite volume effects, partly due to the fixed global topology, are mainly induced by pion fields, the dependence on the lattice volume, topological charge and quark masses can be analytically predicted using chiral perturbation theory (ChPT). We find a good agreement of Dirac operator spectrum calculated on the lattice with the ChPT prediction including its finite size scalings, through which the chiral condensate is determined with good accuracy.

Genetic analysis of several flowering and branching mutants in Pisum sativum L.
Creators: name: Arumingtyas, Estri Laras
Publisher: name: University Of Tasmania
Year: 2023

description: Three flowering mutants and 17 branching mutants were studied. The three induced early flowering mutants showed monogenic inheritance. Mutants L167 and M2/176 are the result of recessive mutations at the established loci Lf and Sn, and the mutant alleles appear equivalent to If and sn, respectively. Mutant M2/137 is the result of a single gene partially recessive mutation at a new flowering locus, for which symbol ppd (photoperiod response) is proposed. Ppd is located on chromosome 1 about 32 cM from A. Fifteen of the 17 branching mutants studied were shown to be single gene recessive mutants while the node of inheritance for two mutants, K319 and K586, was not clear. K319 is possibly a single gene dominant mutant, whereas K586 is possibly a single gene, recessive mutant with weak expression which needs the right conditions to produce laterals. Based on the results of allelism tests, the 17 branching mutants were grouped into 7 series. Mutants WL5147, WL5237, WL5918, Wt15236 and Wt15240 are all allelic and the result of mutation of gene Rms since WL5237 is the type line for rms. Ten further mutants represent mutation at four new ramosus loci designated rms-2 (mutants WL5951 and K524), rms-3 (mutants WL6042, K487, and K564), rms-4 (mutants K164 and Wt15242) and rms-5 (mutants Wt10852, Wt15241 and Wt15244). The remaining two mutants, K319 and K586 do not appear to be allelic with each other or rms-1, 2, 3, 4 or 5 (rms=rms-1).
Lectures on Dark Energy and Cosmic Acceleration

description: The discovery ten years ago that the expansion of the Universe is accelerating put in place the present cosmological model, in which the Universe is composed of 4% baryons, 20% dark matter, and 76% dark energy. Yet the underlying cause of cosmic acceleration remains a mystery: it could arise from the repulsive gravity of dark energy -- for example, the quantum energy of the vacuum -- or it may signal that General Relativity breaks down on cosmological scales and must be replaced. In these lectures, I present the observational evidence for cosmic acceleration and what it has revealed about dark energy, discuss a few of the theoretical ideas that have been proposed to explain acceleration, and describe the key observational probes that we hope will shed light on this enigma in the coming years.

Olbia as a frontier society
Creators: name: Teece, Edwin Philip
Publisher: name: University of British Columbia
Year: 2011

description: In this study the Greek colony of Olbia, on the north coast of the Black Sea, is examined in the light of both the literary and the archaeological evidence relating to the city's first two centuries of settlement. The effects upon the colonists of isolation from the great centres of Greek urban life, of the hostile physical environment into which the Greek settlers transplanted their civilization, and of the barbarian peoples who surrounded the colony are studied. It can be seen from the evidence gathered here that the Olbiopolitai, while struggling to maintain a Greek way of life in their city, yielded in some measure to the artistic, religious and political influences of their Scythian neighbours.

description: This paper is part of the reflection initiated in 2016 following the 20th anniversary of the Public Understanding of Science Journal, analyzing both the thematic evolution of the journal itself and broader aspects of the evolution of the field. Here, we aim to analyze developments in PUS based on all the papers published in the field’s two major journals: Science Communication and Public Understanding of Science. We propose to study the field based on the epistemic relations established between texts resulting from the references they include. Thus, although the aforementioned journals constitute our source of information, by incorporating in the analysis the references of all the papers in these journals – which include books and other journals – we significantly expand the scope and build the epistemic links that are established by the texts analyzed in a very specific way.
Student Housing Choices and Aspirations: Private Renting or Ownership? The Case of Tallinn in Post-socialist Estonia

description: Gaining housing autonomy in ownership-oriented housing systems has been observed as increasingly difficult for contemporary youth, including university students. This article analyses how students make sense of their experiences in private rentals, which is assumed to shape their dispositions and capacities to act in the housing market in the future. We contribute to the conceptualisation of young people’s housing choices and aspirations by offering evidence from the understudied post-socialist context of Tallinn, Estonia. Inspired by Bourdieu’s theory of practice and combining in-depth interviews with a survey, we show how the student experience in a weakly regulated private rental market supports their selfperception as established ‘players’ in the market, while developing a distinct investmentminded disposition to housing. Furthermore, the high symbolic value of homeownership conveyed by families in a ‘super homeownership’ society has rather strengthened among students, despite restricted opportunities to market entry.

The decline of agriculture on the Tasman Peninsula, 1970-1990
Creators: name: Blackwood, WG
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the development of the economy on the Tasman Peninsula. It argues that there have been at least five distinct historical economies. These include the aboriginal economy, the convict period, free settlement, mixed farming and modern agribusiness. Each of these five economies has drawn upon the resources of the area, the skills of the people and available technology to sustain a way of life. In the period of European settlement, the progression of economic development has generally been from relative self sufficiency to a dependent economy strongly controlled by outside influences. Detailed examination of major enterprises that form part of current agricultural practices on the Peninsula illustrate this trend. Local orcharding, dairying and poultry industries have all declined rapidly in recent years as primary production has become dominated by agribusinesses. The detail of the loss of local autonomy varies between enterprises but the overall theme is consistent. It is shown that a higher degree of local economic self sufficiency might be attained by careful resurrection of some past practices. This is not to advocate a return to the past, but to suggest that a future sustainable local economy can best be secured by striking a balance between the old and the new.

description: Making use of the octonion operator, the electromagnetic field generates an adjoint field theoretically. The source of adjoint field includes the adjoint charge and the adjoint current. The adjoint charge has an impact on the gravitational mass and the mass distribution in the electromagnetic field with its adjoint field, and causes further the predictions to departure slightly from the conservation of mass. The inferences can explain why the adjoint charge will influence the mass distribution in the gravitational field and electromagnetic field of celestial bodies. And then the adjoint charge can be considered as one kind of candidate for the dark matter.

description: This article emerges from a transdisciplinary collaboration between a micro-biologist and an anthropologist deeply concerned with the protection of endangered salares (saltpans) in northern Chile. Our aim is to establish the concept of “micro-disaster” as a tool for examining how extractivism is disrupting salares and their “deep-time” microbial ecologies. These ecologies are key for understanding early events on Earth, as their evolution enabled the oxygenation of the planet 2.5 billion years ago and caused the biodiversity explosion. By considering how being human involves being microorganismal – and how human time is entangled with microorganismic time –, this article connects neoliberal extractivist history with geo-biological evolutionary history. “Micro-disasters” therefore affect us deeply as complex humans, and oblige us to develop further a planet-centered mode of collaborating, thinking, feeling, and acting. In the context of this special issue on extinction, we insist that concerns over extinction must be considered in continuity with deep-time ecologies. We propose to rethink humans as an “environmentally complex we” simultaneously entangled with historical experiential time and microbial “deep-time.”

Of particular interest are nonideal bosons which exhibit strong correlation and spatial localization effects. Here we analyse the ground-state of a two-dimensional Bose system with a Hartree-Fock type approximation that was first introduced by Romanovsky et al. [Phys. Rev. Lett. {\bf 93}, 230405 (2004)]. We apply this method to a one dimensional system of charged bosons and analyze the behaviour at strong coupling.

title: ‘Yn ych iaith ych un’: the afterlives of two early Anglo-Welsh poems
Creators: name: Thuillier, Manon Gwendoline Morgane
Publisher: name: University of Glasgow
Year: 2024

description: Building on two preliminary dissertations, Chwedl o Rhydychen: A Study of the Welsh Hymn to the Virgin (M.A., 2017) and The Welsh Hymn to the Virgin: Contexts and Receptions (M.Phil., 2019), this thesis is a study of the manuscripts and early printed editions of the earliest two Anglo-Welsh poems, both dating from the 15th century: Tudur Penllyn’s ‘Y Bardd a Saesnes,’ and Ieuan ap Hywel Swrdwal’s ‘Hymn to the Virgin.’ The two poems distinguish themselves through their language: both were written in Middle to Early Modern English, but their distinctive feature is their deployment of Welsh orthography.

Though the originals are lost, the textual witnesses of these poems survive in great number, with seven manuscripts for ‘Y Bardd a Saesnes’ and thirteen for the ‘Hymn to the Virgin,’ to which can be added three late 18th-and 19th-century printed editions of note. These witnesses are valuable for our understanding of the contexts in which they were transmitted. For that reason, a detailed survey and comparison of these witnesses and their specific features precedes a discussion of the form and significance of the afterlives of the texts, particularly in the context of antiquarianism of the Renaissance and early Romanticism.

The aim of this study is to demonstrate that the transmission, or absence thereof, of these texts, is not linked to any intrinsic qualities they may have, but to the way they answer concerns shared throughout the centuries by their copyists. More specifically, it is held that they reflect the tension between two cultures, the Welsh and the English, and the seeming irreconcilability between the traditionally oppressed and the oppressor: a view that was kept alive through the transmission of foundational myths of Wales.
The American Civil War and military technological change
Creators: name: Bowles, MS
Publisher: name: University Of Tasmania
Year: 2023

description: Military technology change is a subject of enormous diversity and profound complexity. To reduce the topic to some ordered form the thesis discusses military technological changes in one period; the American Civil War from 1861 to 1865. The thesis also contends that military technology cannot be studied in purely physical terms. Only in conjunction with environmental elements can we fully comprehend technical change. This will enable us to make sense of technology as both a technical entity constructed from existing scientific knowledge, and as a human activity interacting with the surrounding environment. The thesis argues that during the war it was possible to establish how non‚ÄövÑvÆtechnical factors concentrated development on traditional weapons technology. Subsequently, technical growth was mainly low risk, cumulative, and based on established technology. Over five years, however, wartime innovations still produced significant advances in technical knowledge. The ultimate success of changes to wartime military technology can therefore be understood by using innovation as a guide. From such a basis one can progress beyond the examination of an individual entity, to also assess the overall innovation process within which technological development occurred. The inquiry leads to an open questioning of existing approaches' ability to fully gauge Civil War military technological change. Popular theories, explaining scientific discovery, fail to provide an appropriate methodological approach by which this thesis may be pursued. Equally, the question of the growth to 'modern war' is addressed early in the thesis. This is done to illustrate the need for a more accurate yardstick that can provide a basis of comparison with 'modern war'. The thesis concludes that study of Civil War innovations can provide the tool with which to identify and assess military technological change. The thesis will be able to highlight that, despite military technological growth being predominantly made by small incremental changes, it nevertheless altered the technical knowledge available to innovators. By identifying the cumulative advances in technical hardware it is possible to illustrate how significant the changes to some military technologies were, when compared to the advances attained prior to the Civil War. It is the identification of non‚ÄövÑvÆtechnical elements, affecting the development of Civil War innovations, that permits the thesis ultimately to make sense of the direction, and the incremental advance of Civil War technical change.

description: We estimate a characteristic timescale for star formation in the spiral arms of disk galaxies, going from atomic hydrogen (HI) to dust-enshrouded massive stars. Drawing on high-resolution HI data from The HI Nearby Galaxy Survey and 24$μ$m images from the Spitzer Infrared Nearby Galaxies Survey we measure the average angular offset between the HI and 24$μ$m emissivity peaks as a function of radius, for a sample of 14 nearby disk galaxies. We model these offsets assuming an instantaneous kinematic pattern speed, $Ω_p$, and a timescale, t(HI-->24$μ$m), for the characteristic time span between the dense \hi phase and the formation of massive stars that heat the surrounding dust. Fitting for $Ω_p$ and t(HI-->24$μ$m), we find that the radial dependence of the observed angular offset (of the \hi and 24$μ$m emission) is consistent with this simple prescription; the resulting corotation radii of the spiral patterns are typically $R_{cor}\simeq 2.7 R_{s}$, consistent with independent estimates. The resulting values of t(HI-->24$μ$m) for the sample are in the range 1--4 Myr. We have explored the possible impact of non-circular gas motions on the estimate of t(HI-->24$μ$m) and have found it to be substantially less than a factor of 2. This implies that a short timescale for the most intense phase of the ensuing star formation in spiral arms, and implies a considerable fraction of molecular clouds exist only for a few Myr before forming stars. However, our analysis does not preclude that some molecular clouds persist considerably longer. If much of the star formation in spiral arms occurs within this short interval t(HI-->24$μ$m), then star formation must be inefficient, in order to avoid the short-term depletion of the gas reservoir.

description: Two series of 12 homologues, 4-(((4-substituentphenyl)imino)methyl)phenyl 4-((4-(alkoxy) benzylidene)amino)benzoate (Dn, X = –OCH3 and En, X = –-Br), have been synthesised. The two series have different alkoxy terminal chains (OCnH2n+1, n = 3, 4, 6, 7, 9, 12) on one side of their structures while other side in the series (Dn and En) was substituted by methoxy and Bromo group, respectively. The structures of the synthesised derivatives have been identified using Fourier transform infrared spectrometry (FT-IR) and nuclear magnetic resonance for H and C (1H-NMR, 13C-NMR) and the elemental analysis (CHN). The texture of liquid crystalline phases of the mesogens has been observed by optical polarised microscopy (OPM) while the details of the thermal transition of compounds were investigated by differential scanning calorimetry (DSC). The obtained liquid crystalline results showed that the derivatives of series (Dn) display a broad range of nematic mesophase (N) while the mesogens of (En) series appeared nematic and smectic mesophases. All the studied homologues show a wide range of liquid crystalline mesophases, the stability of mesomorphic behaviour of these compounds was dependent mainly on the length of terminal alkoxy chain (the number of carbon atoms) chain and the effect of substituent groups (OCH3 and Br).
Words and pictures in a short-term memory task

description: The following series of experiments was designed to investigate verbal and visual coding differences for visually presented words and their corresponding pictures in a STM task. Results show that verbal and visual short-term coding depends on task requirements. In a free recall situation, words and pictures have to be labelled for the response task, and subsequent recall scores reflect verbal coding in both conditions. If verbal coding of pictures can be reduced, as in a recognition task, evidence for verbal and visual short-term coding processes can be obtained in conjunction with verbal interference and rehearsal activities during the retention interval. The damaging effects of verbal interference and the facilitative effects of verbal rehearsal for the verbal short-term store have been reconfirmed in this experiment. The same interpolated activities, in contrast, have been shown to exert an undifferentiated effect on the visual short-term store. The data are interpreted as supporting previous findings of the verbal short-term store characteristics. In contrast, the picture recognition data seem indicative of a visual short-term store. In contrast to the verbal store, however, the visual store shows a lack of, or at least an ineffective rehearsal mechanism in the given experimental situation.
An algorithm for the selection of a method for the modelling of direct-on-line starting of cage induction motors from finite supplies

description: The objective of the study was the derivation of an algorithm for the selection of a numerical simulation method for the direct-on-line starting of induction motors from power supplies whose voltage and frequency may vary during the simulation period. A major part of the work consisted of an evaluation of methods for treating the variation of motor parameters under different conditions and the relative effect of these variations on predicted output. Two new methods were introduced for predicting the variation of leakage reactance with current and a new method was developed for deriving the rotor parameter variation with slip for bars of arbitrary, but known, cross-section. An existing method was modified to derive model parameters from manufacturer's quoted performance data. The results are given of an investigation into the effect on the derived parameters and consequently on the predicted performance, of allowing the quoted performance data to vary within the tolerances permitted by Australian Standard 1359. A set of descriptive measures for simulation output were defined. This enabled the motor's starting performance to be quantified in terms of a small number of variables. The factorial method of experimental design was used to calculate relative coefficients of performance. These related the effect of changes in program input data to the resultant variation in program output and thus allowed numerical measures to be placed on the significance of data uncertainty and model complexity as they affected the simulated performance. PC-based data acquisition and processing techniques were used to take measurements from two laboratory motors which confirmed the results of numerical simulation work. The broad general conclusion of the thesis was that in most situations, the total system data needs to be included in the model if the uncertainty is to be improved beyond that obtainable with simple non-recursive calculations. An expert system shell was used to present an algorithm for the selection of a method of modelling appropriate to the quality of the data, the type of system, the purpose of the study and the availability of computational tools.

description: We study families of one-dimensional matter-wave bright solitons supported by the competition of contact and dipole-dipole (DD) interactions of opposite signs. Soliton families are found, and their stability is investigated in the free space, and in the presence of an optical lattice (OL). Free-space solitons may exist with an arbitrarily weak local attraction if the strength of the DD repulsion is fixed. In the case of the DD attraction, solitons do not exist beyond a maximum value of the local-repulsion strength. In the system which includes the OL, a stability region for \textit{subfundamental solitons} (SFSs) is found in the second finite bandgap. For the existence of gap solitons (GSs) under the attractive DD interaction, the contact repulsion must be strong enough. In the opposite case of the DD repulsion, GSs exist if the contact attraction is not too strong. Collisions between solitons in the free space are studied too. In the case of the local attraction, they merge or pass through each other at small and large velocities, respectively. In the presence of the local repulsion, slowly moving solitons bounce from each other.

title: Geochemical reconstructions of Southern Ocean pH and temperature over the last glacial cycle

description: The Southern Ocean is widely thought to play an important role in atmospheric CO₂ change over glacial-interglacial cycles. It has been suggested that as the region that ventilates the majority of the world’s carbon-rich deep waters today, reduced exchange between deep waters and the atmosphere in the Southern Ocean acted to draw down CO₂ over glacial timescales. However, direct evidence of the Southern Ocean’s role in glacial CO₂ drawdown has been lacking thus far. Here I apply the boron-isotope pH-proxy to foraminifera from the Antarctic Zone sediment core PS1506 over the last glacial cycle. The low boron concentrations in these polar foraminifera makes these samples particularly sensitive to boron blank and so a close examination of the sources of blank, and an assessment of the precision of blank measurements, has been made. The ratios of trace elements to calcium in foraminiferal shells are widely applied as proxies for palaeoenvironmental parameters such as temperature. As Southern Ocean carbonate sediments are particularly prone to dissolution, which can affect trace element concentrations, an assessment of dissolution has been made. Firstly, dissolution experiments were conducted to constrain the impact of dissolution in a controlled setting, and secondly, shell mass and trace elements were evaluated for the downcore record. Imaging reveals similar etching textures in both experimentally dissolved samples and deglacial intervals, when shell mass is also low and several trace elements exhibit an excursion to lower values. Boron isotope data for PS1506 show that during the penultimate interglacial, surface water pH was low. At the onset of atmospheric CO₂ drawdown, pH increased, indicating low CO₂ surface waters. This is consistent with the signature predicted for a more stratified Southern Ocean, and is evidence that stratification in the Antarctic Zone acted to contribute to CO₂ drawdown early in the transition to a glacial state.
