Fundamental experimental study of the operation of gunn effect diodes in resonant circuits
Creators: name: Gergis, Isdoris Sobhi
Publisher: name: University of British Columbia
Year: 2011

description: This work is concerned with a fundamental experimental study of the operation of Gunn effect diodes in microwave cavities. Diodes with different parameters were fabricated from single GaAs crystals. The diodes were tested in resistive circuits for measuring some of their characteristics and for assessing their performance. The effect of the ohmic contacts on the performance of the diodes was demonstrated. Determination of the carrier concentration and mobility for the GaAs crystal was made using the Hall effect and conductivity measurements. Microwave coaxial cavities were designed and built for the operation of the diodes. The cavities had wide tuning range and provided variable impedance at the diode by changing the coupling to the output line. The results obtained showed that the upper limit of the frequency of oscillation varied from about 1.8 f to 2.5 f as the nl product of the diode varied from 0.4 to 3x10¹² cm⁻². At frequencies smaller than the transit time frequency the operation was in two modes; one was the delayed domain mode at lower values of bias. The other was observed at higher bias and was considered to be amultiple domain mode in which the domain reaches the anode before the voltage swings below threshold, and a new domain forms and then gets quenched before a new cycle begins. For the delayed domain mode, a theory has been developed which was in fair agreement with the experimental results. It was found that the range of bias in which the diode could oscillate coherently decreased as both the frequency and the nl product were decreased. The results obtained in the LSA mode showed that the lower limit of oscillation decreased as the carrier concentration decreased, but increased when the bias increased.

description: query in a database system can fail for many reasons, including lack of available data, user error, or conflict between the query and the database semantics. Furthermore, conventional Database Systems (DBS), in most cases, do not incorporate facilities to detect the user intention behind a query. These database systems are therefore not able to provide additional information beyond an answer to a query. While additional or alternative information may not match a query semantically or grammatically, it is often required to support decision-making and to assist in carrying out actions. It is therefore very desirable to develop a mechanism that takes into account factors like user errors, user interests or intention, to prevent a query from failing and to facilitate the retrieval of alternative and relevant information which includes more than the basic answers to an original question.
Exact diagonalization study of the trionic crossover and the trion liquid in the attractive three-component Hubbard model

description: We investigate the trion formation and the effective trionic properties in the attractive Hubbard model with three fermionic colors using exact diagonalization. The crossover to the trionic regime with colorless compound fermions upon increasing strength of the onsite attraction parameter U features smoothly evolving ground state properties and exhibits clear similarities to the BCS/BEC-crossover for two colors. In the excitation spectrum, there is a clear gap opening between a band of well-defined trions and excitations of broken-up trions at U_c ~ 1.8t. This picture remains the same away from the SU(3)-symmetric point. The spatial pairing correlations for colored Cooper pairs are compatible with a power-law at small attractions and change to an exponential decay above the trionic crossover. Furthermore, we show that the effective trionic liquid for U > U_c can be well modeled with spinless 'heavy' fermions interacting with a strong nearest neighbor repulsion.

description: Within the framework of the (3+1)-dimensional Lorentz-violating extended electrodynamics including the CPT-odd Chern-Simons term, we consider the electromagnetic field between the two parallel perfectly conducting plates. We find the one-particle eigenstates of such a field, as well as the implicit expression for the photon energy spectrum. We also show that the tachyon-induced vacuum instability vanishes when the separation between the plates is sufficiently small though finite. In order to find the leading Chern-Simons correction to the vacuum energy, we renormalize and evaluate the sum over all one-particle eigenstate energies using the two different methods, the zeta function technique and the transformation of the discrete sum into a complex plane integral via the residue theorem. The resulting correction to the Casimir force, which is attractive and quadratic in the Chern-Simons term, disagrees with the one calculated in [M.Frank and I.Turan, Phys.Rev.D 74, 033016(2006)], using the misinterpreted equations of motion. Compared to the experimental data, our result places a constraint on the absolute value of the Chern-Simons term.

Theoretical and empirical relationships among data matrices : difficulty, discrimination and similarity
Creators: name: Tindall, Albert Douglas
Publisher: name: University of British Columbia
Year: 2011

description: Theoretical and empirical relationships between paired comparison, PC, same-different choice times and perceived difficulty on a cartwheel task are investigated. An ordering of pairs of stimuli by the use of discrimination choice time predicts the subject's ordering of these pairs according to difficulty of discrimination. Two general models are developed to predict unilateral similarity proportions from PC response latencies. Though both models predict that unilateral similarity proportions are related to directional PC choices, only the ratio of differences model predicts the obtained standard stimulus effect.
Multiple prediction combination and confidence measures for marine object detection
Creators: name: Horton, M
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis considers two problems in classification -- a field within artificial intelligence. One is the general problem of classifier learning, for which a meta-classification technique called 'virtual attribute subsetting' is developed and tested. The other is object detection, with emphasis on marine creature detection, using the 'Haar Classifier Cascade' method (Viola & Jones, 2001b). Haar Classifier Cascades are built from a feature set of simple rectangular patterns of relative light and dark. Adaptive boosting selects those features that best tell the difference between objects and non-objects. In this thesis, a new cascade confidence measure is proposed, equivalent to the boosting 'margin'; it uses information about how well the cascade features match the image region being classified. Tests on the common application of face detection show that this confidence measure improves detection accuracy. Virtual attribute subsetting is also used to modify the cascade; it further improves accuracy at the expense of classification time. In addition, Haar Classifier Cascades are trained to detect two types of marine animal (fish and seahorses). This requires object detection across a wide range of orientations, so approaches using both image and cascade rotation are compared. Results show that image rotation is more accurate than cascade rotation, and that cascades trained to detect objects over a range of angles should have their training images randomly perturbed over a similar (but not always equal) range. Confidence-based detections are also made and show themselves to be more accurate than binary detection. The confidence-based results sum the confidences from similar detections and show that confidence measurements from multiple Haar Classifier Cascades may be combined effectively. Seahorse detection poses an additional problem: seahorses are too flexible to be found by single cascades in any orientation. To solve this, separate seahorse head and body detectors are trained and their detections matched to create whole seahorse detections. Both designed and learnt matching cost formulae are created and two matching algorithms are implemented to link together head and body detections given a cost measurement. The best of the resulting whole seahorse detectors is more accurate than either of the component part detectors. The confidence measurement and virtual attribute subsetting algorithms make no use of domain knowledge, so should improve the accuracy of most other Haar Classifier Cascades. They also have the unusual property of being applicable to already learnt classifiers.

description: Using the example of Liouville theory, we show how the separation into left- and rightmoving degrees of freedom of a nonrational conformal field theory can be made explicit in terms of its integrable structure. The key observation is that there exist separate Baxter Q-operators for left- and right-moving degrees of freedom. Combining a study of the analytic properties of the Q-operators with Sklyanin's Separation of Variables Method leads to a complete characterization of the spectrum. Taking the continuum limit allows us in particular to rederive the Liouville reflection amplitude using only the integrable structure.

description: We show that when an electron or photon propagates in a cylindrically symmetric waveguide, its spin angular momentum (SAM) and its orbital angular momentum (OAM) interact. Remarkably, we find that the dynamics resulting from this spin-orbit interaction are quantitatively described by a single expression applying to both electrons and photons. This leads to the prediction of several novel rotational effects: the spatial or time evolution of either particle's spin/polarization vector is controlled by the sign of its OAM quantum number, or conversely, its spatial wavefunction is controlled by its SAM. We show that the common origin of these effects in electrons and photons is a universal geometric phase. We demonstrate how these phenomena can be used to reversibly transfer entanglement between the SAM and OAM degrees of freedom of two-particle states.

description: The sneutrino is a viable candidate for the NLSP in SUSY spectra with gravitino LSP. In this work we study the collider implications of this possibility. In particular, we investigate whether the LHC can distinguish it (at least, in some cases) from alternative spectra, such as those with a neutralino LSP. We show that there exists a complete family of experimentally allowed and theoretically motivated spectra with sneutrino NLSP, which exhibit very distinctive multilepton signals that are difficult to fake within the MSSM. We study these signals in detail, including the techniques necessary to find them. We demonstrate our analysis approach on simulations incorporating backgrounds.

description: The purpose of this paper is to develop the theory of holomorphic gerbes on complex tori in a manner analogous to the classical theory for line bundles. In contrast to past studies on this subject, we do not restrict to the case where these gerbes are torsion or topologically trivial. We give an Appell-Humbert type description of all holomorphic gerbes on complex tori. This gives an explicit, simple, cocycle representative (and hence gerbe) for each equivalence class of holomorphic gerbes. We also prove that a gerbe on the fiber product of four spaces over a common base is trivial as long as it is trivial upon restriction to any three out of the four spaces. A fine moduli stack for gerbes on complex tori is constructed. This involves the construction of a 'Poincaré' gerbe which plays a role analogous to the role of the Poincaré bundle in the case of line bundles.

Microbiological aspects of an oyster (Crassostrea gigas) hatchery, with special reference to larval mortalities
Creators: name: Lewis, TE
Publisher: name: University Of Tasmania
Year: 2023

description: Investigations of the cause/s of larval mortalities at a commercial Pacific oyster (Crassostrea gigas) hatchery in Tasmania, Australia, were carried out during successive production seasons. Epidemiological evidence suggested that cultures of microalgae, harvested semicontinuously as food for larval oysters (Crassostrea gigas) were the major vectors for transmission of bacterial disease. There was no evidence that bacteria associated with intake seawater, fertilised eggs or hatchery fomites (biofilmed surfaces) caused larval losses, or that non-bacteriological factors (eg. nutrition, gene pool, heavy metal contamination) were responsible for larval mortalities. All microalgal clones (Isochrysis sp. clone T. Iso., Chroomonas salina Butcher 3C, Thalassiosira pseudonana Hasle et Heimdal 3H, Chaetoceros calcitrans Paulsen, Dunaliella salina Butcher, Pavlova (Monochrysis) lutheri Droop, Tetraselmis suecica Butcher) used as food for larvae, were implicated in the transmission of disease. It was apparent that mixed, rather than single, bacterial biotypes were responsible for disease. Bacteria cultured from moribund larvae rarely included presumptive Vibrio or Flavobacterium /Cytophaga spp., and never red-pigmented Pseudomonas spp. When microalgal cultures containing more than `log_10` `6.3` \\(culturable\\) \\(bacteria\\) `mL^-1` were fed to larvae, the larval growth rate was reduced within 2-3 days. Small (15-25%), major (25-90%) or total (> 90%) losses occurred within 1-5 days. If no further cultures of microalgae exceeding the bacterial threshold were fed, surviving animals grew satisfactorily to the ready-to-set stage. If further cultures exceeding the bacterial threshold level were fed further small, major or total (> 90%) losses were experienced within 1-7 days. During the course of the study, techniques for the disinfection of microalgal growth medium were altered from pasteurisation to 0.2 ˜í¬¿m membrane-filtration technology. This resulted in the mean levels of culturable bacteria in the growth media decreasing from `log_10 4.1 mL^- 1` to `log_10 1.5` `100 mL^-1` Scanning electron microscopic examination revealed a decrease in the proportion of microalgal cells colonised by bacteria when microalgal growth medium disinfection techniques changed from pasteurisation cooling to membrane-filtration. The proportion of microalgal cultures (at harvest) containing> `log_10 6.3` `bacteria` `mL^-1` decreased from 55.6% (using pasteurised-cooled seawater as microalgal growth medium), to 20.6% and 10.9% in two successive production seasons during which 0.2 ˜í¬¿m membrane-filtered seawater was used as microalgae growth medium. The yield of ready-to set larvae rose during the same seasons from 1.3% to 3.2% to 4.6% of fertilised eggs.

description: We consider the fist order, gradient-flow, description of the scalar fields coupled to spherically symmetric, asymptotically flat black holes in extended supergravities. Using the identification of the fake superpotential with Hamilton's characteristic function we clarify some of its general properties, showing in particular (besides reviewing the issue of its duality invariance) that W has the properties of a Liapunov's function, which implies that its extrema (associated with the horizon of extremal black holes) are asymptotically stable equilibrium points of the corresponding first order dynamical system (in the sense of Liapunov). Moreover, we show that the fake superpotential W has, along the entire radial flow, the same flat directions which exist at the attractor point. This allows to study properties of the ADM mass also for small black holes where in fact W has no critical points at finite distance in moduli space. In particular the W function for small non-BPS black holes can always be computed analytically, unlike for the large black-hole case.

description: High speed photometry in 2008 shows that the light curve of V842 Cen possesses a coherent modulation at 56.825 s, with sidebands at 56.598 s and 57.054 s. These have appeared since this nova remnant was observed in 2000 and 2002. We deduce that the dominant signal is the rotation period of the white dwarf primary and the sidebands are caused by reprocessing from a surface moving with an orbital period of 3.94 h. Thus V842 Cen is an intermediate polar (IP) of the DQ Herculis subclass, is the fastest rotating white dwarf among the IPs and is the third fastest known in a cataclysmic variable. As in other IPs we see no dwarf nova oscillations, but there are often quasi-periodic oscillations in the range 350 - 1500 s. There is a strong brightness modulation with a period of 3.78 h, which we attribute to negative superhumps, and there is an even stronger signal at 2.886 h which is of unknown origin but is probably a further example of that seen in GW Lib and some other systems. We used the Swift satellite to observe V842 Cen in the ultra-violet and in X-rays, although no periodic modulation was detected in the short observations. The X-ray luminosity of this object appears to be much lower than that of other IPs in which the accretion region is directly visible.

Volunteer Tourism: Does it have a place in development?
Creators: name: Ingram, JM
Publisher: name: University Of Tasmania
Year: 2023

description: Everywhere you look today people are being drawn, often unawares, into the trend of 'development': sponsored charity walks, pay per click internet fundraising, the donation of time and money, concerts and album recordings, 'Fairtrade' shopping. Whilst living in the UK in the early 2000s it became increasingly noticeable to me that in the highly competitive charity and travel sectors alternatives were being sought to either assist in the development of poor communities or to attract customers via new products. Volunteering as part of a holiday was becoming the new 'fad'. Promoted as an opportunity to experience a different culture whilst doing something constructive and worthwhile for a developing community, it was the new fashionable way to 'do development'. Like many other initiatives in development, concern has been raised as to whether volunteer tourism can truly add value to the development of poor communities. Is it, in fact, merely a tourism product? This thesis is an innovative attempt to call volunteer tourism to account. Through examination of the new phenomenon and an analysis of literature and examples in relation to development and volunteer tourism, it will consider whether volunteer tourism has a place in development. To do so, the first chapter will examine the ground breaking initiatives that have infiltrated the development cause in recent decades and assess the value they have provided in poverty alleviation and capacity building. Chapter Two, focuses on one ground breaking initiative in particular, volunteer tourism. The main interest of Chapter Two is to introduce the reader to the concept of volunteer tourism and to evaluate it as a niche tourism product in today's post modern world. Chapter Three provides an analysis of development initiatives of the past and what approaches have the greatest potential for success. This analysis forms the basis of an examination later in the chapter; assessing whether volunteer tourism fits within the framework of development. Finally, concluding remarks highlight the complexity of the volunteer tourism concept and call for further research into the new phenomenon ‚Äö- volunteer tourism.

Data were obtained for testing a Markov model, a Subjective Expected Utility model and a Rational Motive Pursuit (né Stochastic Choice) model. Results indicated some support for all models, however the Markov model appeared to predict the data most accurately, the R.M.P. model less accurately and the S.E.U. model least accurately. Much of the data were interpreted In terms of each model and a theoretical synthesis of them was proposed.

description: We investigate the role of equilibrium methods and stress transfer range in describing the process of damage. We find that equilibrium approaches are not applicable to the description of damage and the catastrophic failure mechanism if the stress transfer is short ranged. In the long range limit, equilibrium methods apply only if the healing mechanism associated with ruptured elements is instantaneous. Furthermore we find that the nature of the catastrophic failure depends strongly on the stress transfer range. Long range transfer systems have a failure mechanism that resembles nucleation. In short range stress transfer systems, the catastrophic failure is a continuous process that, in some respects, resembles a critical point.

Virginia Woolf's short fiction : a study of its relation to the story genre, and an explication of the known story canon
Creators: name: Tallentire, David Roger
Publisher: name: University of British Columbia
Year: 2011

description: The short stories of Virginia Woolf have never received serious scrutiny, critics determinedly maintaining that the novels contain the heart of the matter and that the stories are merely preparatory exercises. Mrs. Woolf, however, provides sufficient evidence that she was "on the track of real discoveries" in the stories, an opinion supported by her Bloomsbury mentors Roger Fry and Lytton Strachey. A careful analysis of her twenty-one known stories suggests that they are indeed important (not merely peripheral to the novels and criticism) and are successful in developing specific techniques and themes germane to her total canon. One of the reasons why the stories have never been taken seriously, of course, is that they simply are not stories by any conventional definition— but are nonetheless "short fiction" of interest and significance. The stories derive from three distinctly separate chronological periods. The earliest group (1917-1921) was published in Monday or Tuesday and included two stories available only in that volume, now out of print. (To enable a complete assessment, I have made these stories available as appendices II and III of this thesis, and included Virginia Woolf's lone children's story as appendix IV since it too is of the early period). This phase of creation utilized one primary technique—that of evolving an apparently random stream of impressions from a usually inanimate and tiny focussing object, and was generally optimistic about the "adorable world." The second phase of her short fiction (those stories appearing in magazines between 1927 and 1938) illustrates a progression in both technical virtuosity and in personal discipline: the fictional universe is now peopled, and the randomness of the early sketches has given way to a more selective exploitation of the thoughts inspired by motivating situations. But vacillation is here evident in the author's mood, and while optimism at times burns as brightly as before, these stories as often presage Mrs. Woolfs abnegation of life. The third group, posthumously published by Leonard Woolf in 1944 without his wife's imprimatur (and recognizably "only in the stage beyond that of her first sketch"), still reveals a desire in the author to pursue her original objective suggested in "A Haunted House"--the unlayering of facts to bare the "buried treasure" truth, using imagination as her only tool. In one respect, and one/Only, the critics who have neglected these stories are correct: the pieces are often too loosely knit, too undisciplined, and too often leave the Impression of a magpie's nest rather than one "with twigs and straws placed neatly together." In this the stories are obviously inferior to the novels. But by neglecting the stories the critics have missed a mine of information: herein lies an "artist's sketchbook,” which, like A Writer's Diary, provides a major avenue into the mind of one of the most remarkable writers of our age.

description: Engagement of target groups is a core aspect of Made4You. As one of the aims is to build an
 ecosystem by linking existing local communities of citizens with disabilities and their
 families, healthcare professionals and makers it is important that one of the core strategies
 of the project is to interact with these communities and establish collaboration between
 these separate communities to develop their own open source and license interventions.
 Communication and engagement via different means are core to reach the target groups
 and in workpackage 1 we focus on a series of events as a core means to engage and
 collaborate.
 In this deliverable we first describe how we plan to engage the different stakeholders with
 the final aim to make them users of the careables services, namely co-design sessions and
 the careables platform. This document has been elaborated in close collaboration with the
 team responsible for project communication, dissemination and outreach. It is important to
 stress that depending on the context and the target groups different engagement methods
 should be applied. The Made4You partners have defined a strategy of how to move people
 from becoming aware of careables to being informed and finally to actively participate.
 During the first year the project team already held 25 open days, 28 workshops, 4
 educational events, 7 maker gatherings and 42 presentations of the project to diverse
 audiences. During the Made4you open days and even during presentations, hosted at
 different locations, many ideas for careables were developed. The open healthcare solutions
 our participants have come up with a very diverse and range from a smart pill box to a smart
 toy and pimped cane for a blind person. Some of these open solutions are presented in this
 deliverable.
 Drawing from first experiences we developed some guidelines on how to best organize
 careables engagement events. These guidelines are included in this document and should
 help other maker spaces or open healthcare interested audiences to start their own co-
 design sessions for open health and care solutions.

Truth or trap: the Australian contemporary crafts movement's pursuit of art ideals
Creators: name: Cochrane, GD
Publisher: name: University Of Tasmania
Year: 2023

description: The contemporary crafts movement was a phenomenon in the Western world, including Australia, from the 1940s. Its roots were in the philosophies of the British Arts and Crafts movement of the late 19th century, and in the simultaneous expression of ideals of a new democracy through community life that included aspirations towards self-suffiency through crafts production. It was encouraged by progressive education policies from the 1920s and the related model of expressive individualism in the United States from the 1940s. It also reflected post-war responses to ideals of economic 'progress', to domestic consumerism, to new industrial products and processes and to the development of Modernism in art, design and industry. The leaders of the contemporary crafts movement used the terms 'the crafts' or 'craft' as an umbrella for a wide range of practices under which to present a perception of cohesive identity and political force. In the early 1970s the movement gained the support of government funding, influenced the inclusion of crafts courses in educational institutions and developed a wide popular marketplace. The contemporary crafts movement's early ideals and values placed an emphasis on the revival or re-invention of traditions of skilfully making beautiful, utilitarian objects by hand from natural materials. From the late I 960s, however, in seeking the status of art and artists, an increasing number of craftspeople started to pursue instead, the ideals followed by the fine arts at that time, ideals that themselves shifted during the 1970s and were contrary to crafts traditions. This thesis will review the historical background of the Australian contemporary crafts movement's pursuit of art ideals, discuss the tensions that developed between different philosophies of crafts practice and account for the parallel relationship with design and industry. In particular, it will review the subsequent effect of the crafts movement's pursuit of art ideals. While the influence of art ideals clearly served to successfully challenge conservative aspects of crafts traditions, I will argue that the pursuit of these ideals also contributed to a loss of identity in crafts practice, a loss that has been under review from the mid-1980s. I will argue that craftspeople should have confidence in acknowledging and valuing the wider histories and traditions that underlie their contemporary practice, including, but not without critical appraisal of, the influence of contemporary art values.

description: Approximate Bayesian computation (ABC) or likelihood-free inference algorithms are used to find approximations to posterior distributions without making explicit use of the likelihood function, depending instead on simulation of sample data sets from the model. In this paper we show that under the assumption of the existence of a uniform additive model error term, ABC algorithms give exact results when sufficient summaries are used. This interpretation allows the approximation made in many previous application papers to be understood, and should guide the choice of metric and tolerance in future work. ABC algorithms can be generalized by replacing the 0-1 cut-off with an acceptance probability that varies with the distance of the simulated data from the observed data. The acceptance density gives the distribution of the error term, enabling the uniform error usually used to be replaced by a general distribution. This generalization can also be applied to approximate Markov chain Monte Carlo algorithms. In light of this work, ABC algorithms can be seen as calibration techniques for implicit stochastic models, inferring parameter values in light of the computer model, data, prior beliefs about the parameter values, and any measurement or model errors.

description: Particle size polydispersity can help to inhibit crystallization of the hard-sphere fluid into close-packed structures at high packing fractions and thus is often employed to create model glass-forming systems. Nonetheless, it is known that hard-sphere mixtures with modest polydispersity still have ordered ground states. Here, we demonstrate by computer simulation that hard-sphere mixtures with increased polydispersity fractionate on the basis of particle size and a bimodal subpopulation favors the formation of topologically close-packed C14 and C15 Laves phases in coexistence with a disordered phase. The generality of this result is supported by simulations of hard-sphere mixtures with particle-size distributions of four different forms.

description: We classify all possible new U(1) x SU(2) x SU(3) multiplets that can couple to pairs of SM particles. Assuming that production of such new particles is dominated by their gauge interactions we study their signals at LHC, finding the following five main classes: i) lepto-quark 2l 2q signals; ii) di-lepton 4l signals; iii) di-quarks 4j signals, iv) heavy-lepton 2l 2V signals and v) heavy quarks 2j 2V signals, where V denotes heavy SM vectors (with W being associated to exotic fermions). In each case we outilne the most promising final states, the SM backgrounds and propose the needed searches.

description: It is not so well-known that measurement-free quantum error correction protocols can be designed to achieve fault-tolerant quantum computing. Despite the potential advantages of using such protocols in terms of the relaxation of accuracy, speed and addressing requirements on the measurement process, they have usually been overlooked because they are expected to yield a very bad threshold as compared to error correction protocols which use measurements. Here we show that this is not the case. We design fault-tolerant circuits for the 9 qubit Bacon-Shor code and find a threshold for gates and preparation of $p_{(p,g) thresh}=3.76 \times 10^{-5}$ (30% of the best known result for the same code using measurement based error correction) while admitting up to 1/3 error rates for measurements and allocating no constraints on measurement speed. We further show that demanding gate error rates sufficiently below the threshold one can improve the preparation threshold to $p_{(p)thresh} = 1/3$. We also show how these techniques can be adapted to other Calderbank-Shor-Steane codes.

description: Australia has an abundance of saline groundwater due to land clearing and irrigation within the Murray-Darling river system. Generally saline groundwater contains similar ions to coastal seawater with concentrations varying due to the source of the water. In this study Australian snapper (Pagrus auratus), mulloway (Argyrosomus japonicus) and yellowtail kingfish (Seriola lalandi) were chosen to examine their suitability for culture in saline groundwater. The growth and metabolic response of the aforementioned species were investigated to determine their suitability for culture in saline groundwater from the 'outfall' of the Stockyard Plains Disposal Basin (SPDB) in Waikerie, South Australia (potassium ~ 80 mg.L-1). In the first experiment snapper, mulloway and yellowtail kingfish were cultured in saline groundwater (salinity = 19 ¬¨¬± 1 g.L-1), half-strength coastal seawater (iso-osmotic; 19 ¬¨¬± 1 g.L-1) and oceanic seawater (except snapper; 37 ¬¨¬± 1 g.L-1) for 61, 45 and 21 days respectively, to determine survival, growth rate and food conversion ratio. At the end of each growth experiment, fish were placed in static box respirometers to record changes in oxygen consumption in the different water types. Changes in oxygen consumption were used as an indirect method to determine routine metabolic rate (Mo2rout), maximum metabolic rate (Mo2max) and metabolic scope (Mo2scope). In the second experiment, blood samples were taken from the fish 1 hour postexhaustion and analysed for blood plasma sodium, potassium, chloride, lactate and osmolality to determine if fish were able to cope with osmoregulatory changes.
Minimum distance regression model checking with Berkson measurement errors

description: Lack-of-fit testing of a regression model with Berkson measurement error has not been discussed in the literature to date. To fill this void, we propose a class of tests based on minimized integrated square distances between a nonparametric regression function estimator and the parametric model being fitted. We prove asymptotic normality of these test statistics under the null hypothesis and that of the corresponding minimum distance estimators under minimal conditions on the model being fitted. We also prove consistency of the proposed tests against a class of fixed alternatives and obtain their asymptotic power against a class of local alternatives orthogonal to the null hypothesis. These latter results are new even when there is no measurement error. A simulation that is included shows very desirable finite sample behavior of the proposed inference procedures.

Tasmanian bat ecology : conservation of native fauna
Creators: name: Inada, M
Publisher: name: University Of Tasmania

description: Conservation of biodiversity is one of the most important issues globally. Chiropteran fauna contributes one quarter of mammalian species but little information is known about most species. Tasmania has eight known species of bats including one endemic species, Nyctophilus.sherrini. There have been a number of studies conducted in Tasmania, yet much of the biology and ecology of most species remains unclear. Effective conservation of local biodiversity requires scientific information such as distribution, habitat relationships, and feeding behaviours. The present study contributes new information about the distribution for most species in Tasmania by using Anabat detector systems. Identification of species by their echolocation calls sampled from free flying individuals was achieved, by developing a regional key derived from trapped bats and an automated identification program, Anascheme. Six species/species groups were successfully distinguished by the key. Distribution records were gathered by echolocation recordings and the key newly developed for the study. I found that most sites have high bat species richness, as more than four species were recorded at the majority of sites. Three Vespadelus species were the most commonly observed and the Southern Forest Bat, V. regulus, was recorded at 100% of sites. In contrast, the high-flying Eastern Falsistrelle, Falsistrellus tasmaniensis, was only present at only 17% of sites. Species-habitat relationships were analysed where possible. Tasmanian bats appeared to have less species-specific requirements in their preferred activity areas. In addition to spatial partitioning of niches, the possibility of discrete temporal activity patterns of species was examined. Calls recorded for each species were assigned into 10 equal-time intervals between sunset and sunrise. There were no significant differences in a total activity index between time intervals by species, suggesting a high level of activity throughout the night. Evidence of a weak bimodal pattern in nightly activity was recognised in several species. Emergence timing was also compared between species, and F. tasmaniensis was shown to have a significantly later emergence time, and thus later peak activity timing than the others. Although analysis detected no significant effects of weather conditions on different observation nights, nightly fluctuations in the activity of several bats were apparent.
