description: Natural history collections are uniquely positioned to chronicle biodiversity changes across time and space and are a fundamental data source in taxon-based research and conservation. With over 90 species listed under the Endangered Species Act, freshwater mussels are one of the most imperiled animal assemblages in the United States and are the focus of considerable conservation efforts (e.g., species status assessments, listing decisions, and recovery plans). Unfortunately, natural history collections data is often underleveraged in such efforts, in part, because much of the data are decentralized and nonstandard, and thus, difficult to access and analyze. Our objective herein is to synthesize, standardize, and enrich digitized US freshwater mussel collections data to better suit the needs of conservation stakeholders. We aggregated specimen records from 45 US natural history collections and enriched these records by programmatically standardizing taxonomic information, flagging potentially problematic records, and joining records with freshwater-specific spatial frameworks (e.g., hydrological units and stream segments) and their associated metadata (e.g., area, stream order, discharge, velocity). The assembled dataset includes 410,665 records, 302 species, and 1,494 hydrological units (8 digit-level). Using these enriched records, we estimated ecological attributes for over 280 freshwater mussel species including aspects of range size (i.e., area of occupancy and change in area of occupancy) and habitat preferences (i.e., stream order size, discharge, slope, and velocity). Listed species had significantly fewer occurrences (p<0.001) and smaller area of occupancy (p<0.001) in comparison to non-listed listed species. Listed species also tended to have a higher stream order preference (p<0.001) and discharge preference than non-listed species (p<0.001). These important ecological attributes have not been incorporated into freshwater mussel conservation efforts in a quantitative way and our novel estimates can be used to make more data-driven ecological and conservation inferences.

description: We examine the metallicity and age of a large set of SDSS/DR6 galaxies that may be Blue Compact Dwarf (BCD) galaxies during quiescence (QBCDs).The individual spectra are first classified and then averaged to reduce noise. The metallicity inferred from emission lines (tracing ionized gas) exceeds by ~0.35 dex the metallicity inferred from absorption lines (tracing stars). Such a small difference is significant according to our error budget estimate. The same procedure was applied to a reference sample of BCDs, and in this case the two metallicities agree, being also consistent with the stellar metallicity in QBCDs. Chemical evolution models indicate that the gas metallicity of QBCDs is too high to be representative of the galaxy as a whole, but it can represent a small fraction of the galactic gas, self enriched by previous starbursts. The luminosity weighted stellar age of QBCDs spans the whole range between 1 and 10 Gyr, whereas it is always smaller than 1 Gyr for BCDs. Our stellar ages and metallicities rely on a single stellar population spectrum fitting procedure, which we have specifically developed for this work using the stellar library MILES.

description: The many-body dynamics exhibited by living objects include group formation within a population, and the non-equilibrium process of attrition between two opposing populations due to competition or conflict. We show analytically and numerically that the combination of these two dynamical processes generates an attrition duration T whose nonlinear dependence on population asymmetry x is in stark contrast to standard mass-action theories. A minority population experiences a longer survival time than two equally balanced populations, irrespective of whether the majority population adopts such internal grouping or not. Adding a third population with pre-defined group sizes allows T(x) to be tailored. Our findings compare favorably to real-world observations.
The Age of consent : news, crime and public debate

description: In 2009 in Hobart, Australia, a 12-¬¨‚â†year-¬¨‚â†old ward of the state was advertised in a metropolitan newspaper as an 18-¬¨‚â†year-¬¨‚â†old prostitute. The decision to only prosecute one of the 100-¬¨‚â†plus men estimated to have paid for sex with the child was a scandal that made national headlines. Sustained coverage over the next two years was notable for its representation of community outrage, which included allegations of a cover up involving the highest levels of government and the judiciary. This thesis is both an examination of the news coverage of the controversy and an attempt to theoretically understand the relationship between contemporary journalistic practice, representations of crime and mediatised controversy. Using a methodology that draws on content and frame analysis of news and other texts, and interviews with journalists and their sources, this study seeks to identify the point at which socially useful news coverage of complex legal matters tips into panic (McNair 2006). This investigation examines how Tasmanian media framed the coverage of this matter; how journalist-¬¨‚â†source relationship informed the coverage; and what journalistic practices and communications strategies contributed to the sense of confusion and distrust that informed the controversy. Its key findings demonstrate the extent to which ideas of news values are both fluid and an important factor in how journalists and their sources identify opportunities for news making, that news coverage and news framing is significantly dependent on the sponsorship of sources, and that these relationships, combined with the communications strategies of government, the judiciary and other actors, contributed to the apparent politicisation and outrage. The capacity of journalism to contribute to democratic deliberation at a time of radical change is currently under scrutiny. The findings of this investigation provide a nuanced observation of the extent to which the source-¬¨‚â†journalist relationship determines the quality of reporting and public debate.

description: Photoproduction of $η$ mesons off $^{12}$C, $^{40}$Ca, $^{93}$Nb, and $^{nat}$Pb nuclei has been measured with a tagged photon beam with energies between 0.6 and 2.2 GeV. The experiment was performed at the Bonn ELSA accelerator with the combined setup of the Crystal Barrel and TAPS calorimeters. It aimed at the in-medium properties of the S$_{11}$(1535) nucleon resonance and the study of the absorption properties of nuclear matter for $η$ mesons. Careful consideration was given to contributions from $ηπ$ final states and secondary production mechanisms of $η$-mesons e.g. from inelastic $πN$ reactions of intermediate pions. The analysis of the mass number scaling shows that the nuclear absorption cross section $σ_{Nη}$ for $η$ mesons is constant over a wide range of the $η$ momentum. The comparison of the excitation functions to data off the deuteron and to calculations in the framework of a BUU-model show no unexplained in-medium modifications of the S$_{11}$(1535).

Effects of hydrodynamic interaction on an AUV operating close to a moving submarine
Creators: name: Leong, ZQ
Publisher: name: University Of Tasmania
Year: 2023

description: The work detailed in this thesis investigates the behaviour of the hydrodynamic interaction effects acting on an unappended AUV manoeuvring in proximity to a larger moving underwater vehicle such as a submarine. The investigation examined the steady-state and transient interaction effects on the hydrodynamic coefficients of the AUV as a function of the relative: speed, longitudinal position, lateral position, and size between the two submerged vehicles. The work involved extensive development of Computational Fluid Dynamics (CFD) models to simulate the manoeuvres in order to map the interaction behaviour. Experimental Fluid Dynamics (EFD) involving captive-model tests of the two vehicles were carried out to validate and supplement the CFD data. The results show that the hydrodynamic interaction acts to attract and repel the AUV at the stern and bow regions around the submarine, respectively. The magnitude of these attraction and repulsion interaction effects varied significantly due to small changes in the relative longitudinal position, suggesting the need of an accurate and fast responsive control system for the AUV to adequately maintain its trajectory around the submarine. These adverse interaction effects were found to be minimal around amidships of the moving submarine, suggesting a safe path for the AUV to approach or depart the submarine laterally within that region. In addition, the interaction effects on the hydrodynamic coefficients of the AUV were shown to reduce as the relative speed of the latter increased. Due to the need to simulate large relative motions between the two vehicles, this thesis also investigate and identifies the merits of two dynamic mesh techniques within ANSYS CFX (i.e. Immersed Solids, and AMP Re-Meshing) to simulate multiple bodies in relative motion. Although the numerical models behind the techniques have undergone substantial development in recent years, as they are beta-features in ANSYS CFX there are currently no existing studies demonstrating their capabilities in modelling multiple bodies in relative motion. The developed CFD simulation models are suitable for future work involving appended AUVs and the coupling with a control system for manoeuvring simulations of multiple underwater vehicles.
Electron paramagnetic resonance of heavily-doped n-type silicon
Creators: name: Quirt, John David
Publisher: name: University of British Columbia
Year: 2011

description: Spin susceptibility, g-value, and EPR linewidth data are presented for phosphorus-doped silicon samples having impurity concentrations 10¹⁸ donors/cm³ < N[sub D] 10²⁰ donors/cm³. These results are compared with the predictions of alternative simple models of the semiconductor-to-metal transition in heavily-doped semiconductor materials. At low concentrations (N[sub D] < 3 x 10¹⁸ donors /cm³) our samples behave as semiconductors in transport experiments, and are characterized by Curie-Weiss Law spin susceptibilities. Near the upper limit of our sample impurity concentration range (N[sub D] ~ 10²⁰ donors/cm³) transport properties indicate "metallic" properties and the spin susceptibility data may be represented by the Pauli expression with an effective mass slightly smaller than that usually associated with the silicon conduction band. A good representation of the experimental spin susceptibilities can be achieved with an expression which is the sum of two terms, one of which is of the Curie-Weiss form, and the other of the Pauli type. Previously published Hall coefficient data is analysed to establish the relationship between these susceptibility components and non-conducting (or partially localized) and conducting extrinsic electrons respectively. The inferred presence of partially-localized electrons even in samples with N[sub D] > 10¹⁹ donors/cm³ is discussed with respect to previously published magnetoresistance and Knight Shift data. For high impurity concentrations (N[sub D] > 10¹⁹ donors/cm³) additional analysis of the experimental data with respect to theoretical models appropriate for electrons in silicon conduction band states is presented.

The Virgo Over-density is seen to comprise two filaments 14.5 x 3 degrees and 10 x 3 degrees and a circular structure 3 degrees in diameter. Together the three features span 38 degrees of right ascension and declinations of +2 to -15 degrees. RR Lyrae variables place the two filamentary features at heliocentric distances of 20 and 17 kpc respectively, with projected dimensions of 5 x 1 kpc and 3 x 1 kpc.

Would you like genes with that? : Romanticism and the debate over genetically modified food
Creators: name: Gash, LJ
Publisher: name: University Of Tasmania
Year: 2023

description: For over thirty years a debate has raged over genetically modified (GM) food. While a wide range of individuals and organisations have waged a vitriolic campaign against GM food and its proponents, a number of GM crops have met with widespread adoption in the USA, Australia and elsewhere. It is surprising that after so many years, with around 70% of processed food in the USA containing GMOs, the anti-GM movement's main debating points and the level of emotion in their expression have changed little. The aim of this thesis is to explore whether one of the factors motivating the anti-GM cause is romanticism. This worldview, and its polar opposite, classicism (or scientism), are explored through an examination of the readings in sociology, philosophy, psychology and politics on this subject. This is followed by a discussion of the influence of romanticism on the modern green movement and alternative attitudes to food, as well as its relationship with science. While initially discussing both romanticism and classicism, the reasons for focussing on romanticism are that the views of GM proponents are fairly straightforward ‚Äö- GMOs are created to provide an advantage in particular agricultural food production systems, the science is sound and they make a profit, but romanticism as a worldview, though widely referenced in the arts and occasionally discussed as an influence in the environment movement, is rarely discussed in detail. Supporters of anti-GM Facebook pages based in Australia were surveyed using an instrument designed to assess a person's relative position on the Romanticism‚Äö-Classicism spectrum. The participants were found to score significantly at the romanticism end of the scale. The answers to open questions about attitudes to GM food contained emotionally charged phrases consistent with a romantic outlook. The findings are consistent with the proposition that individuals involved with the movement against GM food in Australia are influenced by a worldview based on romanticism.

The Coming of the Celts, AD 1862: Celtic Nationalism in Ireland and Wales
Creators: name: De Barra, Caoimhín
Publisher: name: University of Notre Dame
Year: 2023

description: Who are the Celts, and what does it mean to be Celtic? In this book, Caoimh\u00edn De Barra focuses on nationalists in Ireland and Wales between 1860 and 1925, a time period when people in these countries came to identify themselves as Celts. De Barra chooses to examine Ireland and Wales because, of the six so-called Celtic nations, these two were the furthest apart in terms of their linguistic, religious, and socioeconomic differences.\u000a\u000a_The Coming of the Celts, AD 1860_ is divided into three parts. The first concentrates on the emergence of a sense of Celtic identity and the ways in which political and cultural nationalists in both countries borrowed ideas from one another in promoting this sense of identity. The second part follows the efforts to create a more formal relationship between the Celtic countries through the Pan-Celtic movement; the subsequent successes and failures of this movement in Ireland and Wales are compared and contrasted. Finally, the book discusses the public juxtaposition of Welsh and Irish nationalisms during the Irish Revolution.\u000a\u000aDe Barra's is the first book to critique what 'Celtic' has meant historically, and it will appeal to the reader who wants to learn more about the modern political and cultural connections between Ireland and Wales, as well as scholars and students in the fields of modern Irish and Welsh history. It will also be of interest to professional historians working in the field of 'Four Nations' history, which places an emphasis on understanding the relationships and connections between the four nations of Britain and Ireland.
An accurate analytic description of neutrino oscillations in matter

description: A simple closed-form analytic expression for the probability of two-flavour neutrino oscillations in a matter with an arbitrary density profile is derived. Our formula is based on a perturbative expansion and allows an easy calculation of higher order corrections. The expansion parameter is small when the density changes relatively slowly along the neutrino path and/or neutrino energy is not very close to the Mikheyev-Smirnov-Wolfenstein (MSW) resonance energy. Our approximation is not equivalent to the adiabatic approximation and actually goes beyond it. We demonstrate the validity of our results using a few model density profiles, including the PREM density profile of the Earth. It is shown that by combining the results obtained from the expansions valid below and above the MSW resonance one can obtain a very good description of neutrino oscillations in matter in the entire energy range, including the resonance region.

description: We use QCD sum rules to test the nature of the meson X(3872), assumed to be a mixture between charmonium and exotic molecular [c\bar{q}][q\bar{c}] states with J^{PC}=1^{++}. We find that there is only a small range for the values of the mixing angle, θ, that can provide simultaneously good agreement with the experimental value of the mass and the decay width, and this range is θbetween 5 and 13 degrees. In this range we get m_X=(3.77 \pm 0.18) GeV and Γ(X to J/ψπ^+ π^-)=(9.3 \pm 6.9) MeV, which are compatible, within the errors, with the experimental values. We, therefore, conclude that the X(3872) is approximately 97% a charmonium state with 3% admixture of \sim 88% D^0D^{*0} molecule and \sim 12% D^+D^{*-} molecule.

description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
In recent years, an ever increasing number of golfers have sought to increase their drive distance (DD) due to the positive associations it has with scoring. For instance, DP World Tour golfers who hit the ball over greater distances achieved significantly lower scores on par5 holes during the 2017 to 2019 seasons. One possible avenue of enhancing DD is through engaging in strength and conditioning (S&C) since this provides a golfer with greater capacity to generate force. During the downswing, ground reaction forces work in all three principal directions, however, the greatest magnitude occur in the vertical direction. As such, physically profiling golfers using vertically orientated tasks would appear both logical and appropriate. Previous research has reported significant relationships when comparing clubhead velocity (CHV) to a 1-repetition maximum back squat and countermovement jump (CMJ) height. More recent research using forces plates has reported significant relationships between CHV and both CMJ impulse and isometric mid-thigh pull (IMTP) peak force (PF). To date, however, there is no research that has sought to assess the associations between CMJ impulse and DD within elite DP World Tour golfers. Therefore, the aims of this investigation were to assess if CMJ net impulse (NI), CMJ positive impulse (PI) and IMTP PF significantly accounted for the variance in elite DP World Tour golfers’ DD.
Perpendicular Ion Heating by Low-Frequency Alfven-Wave Turbulence in the Solar Wind

description: We consider ion heating by turbulent Alfven waves (AWs) and kinetic Alfven waves (KAWs) with perpendicular wavelengths comparable to the ion gyroradius and frequencies smaller than the ion cyclotron frequency. When the turbulence amplitude exceeds a certain threshold, an ion's orbit becomes chaotic. The ion then interacts stochastically with the time-varying electrostatic potential, and the ion's energy undergoes a random walk. Using phenomenological arguments, we derive an analytic expression for the rates at which different ion species are heated, which we test by simulating test particles interacting with a spectrum of randomly phased AWs and KAWs. We find that the stochastic heating rate depends sensitively on the quantity epsilon = dv/vperp, where vperp is the component of the ion velocity perpendicular to the background magnetic field B0, and dv (dB) is the rms amplitude of the velocity (magnetic-field) fluctuations at the gyroradius scale. In the case of thermal protons, when epsilon << eps1, where eps1 is a constant, a proton's magnetic moment is nearly conserved and stochastic heating is extremely weak. However, when epsilon > eps1, the proton heating rate exceeds the cascade power that would be present in strong balanced KAW turbulence with the same value of dv, and magnetic-moment conservation is violated. For the random-phase waves in our test-particle simulations, eps1 is approximately 0.2. For protons in low-beta plasmas, epsilon is approximately dB/B0 divided by the square root of beta, and epsilon can exceed eps1 even when dB/B0 << eps1. At comparable temperatures, alpha particles and minor ions have larger values of epsilon than protons and are heated more efficiently as a result. We discuss the implications of our results for ion heating in coronal holes and the solar wind.

description: We perform a theoretical study of composite superconducting qubit systems for the case of a coupled qubit configuration based on a hybrid qubit circuit made of both charge and phase qubits, which are coupled via a sigma(x)xsigma(z) interaction. We compute the system's eigen-energies in terms of the qubit transition frequencies and the strength of the inter-qubit coupling, and describe the sensitivity of the energy crossing/anti-crossing features to such coupling. We compute the hybrid system's dissipative dynamics for the cases of i) collective and ii) independent decoherence, whereby the system interacts with one common and two different baths of harmonic oscillators, respectively. The calculations have been performed within the Bloch-Redfield formalism and we report the solutions for the populations and the coherences of the system's reduced density matrix. The dephasing and relaxation rates are explicitly calculated as a function of the heat bath temperature.

Dynamics of trending topics : smart service systems using trending topics
Creators: name: Han, SC
Publisher: name: University Of Tasmania
Year: 2023

description: What is the definition of trending topic? Trending topic is the topic that a great amount of people are interested in. While trending topics could be detected from the offline survey or newspaper in the past, those topics can be easily detected from online these days. The rise of new types of social networking services, such as Facebook or Twitter, has caused the accumulation of unprecedented amount of web social data. This large amount of social data attracts many researchers' and companies' attention since it enables to collect and monitor the social interests with reducing the time and cost for the quantitative survey. Almost all web and social networking services analyze their user created social data and detect the most popular terms that are discussed and searched by their users. The popular terms are detected and published in the list, called 'Trending Topic' list. Awareness and utilization of trending topics plays a crucial role in various fields, including marketing, politics, and economics. This dissertation focuses on the following three studies. The first study is to analyse the nature of trending topics and reveal the important aspects. The second study is to identify the relevance of trending topic to a target object, such as individuals or organisations. It discovers how a trending topic affects a target group or individual. The impact strength of a trending topic is closely related to the strength of the relationship between the user and the issue. Therefore, this study will propose a method to identify the relevance between users and trending topics. The last study is to develop the model that predicts the trends of trending topics in the future. This study focuses on the formation and fading of trending topics and the trend during this lifecycle. Moreover, the dissertation also propose a model that represents the diffusion drifting movement of trending topic among different online communities

Does BMI moderate the effects of social cues on snacking?
Creators: name: Revell, SR
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of the present study is to investigate BMI as a predictor of the likelihood that social cues effect snacking behaviour. Increased BMI is associated with increased impulsivity and poor self-regulation. Snacking in a social context is largely ambiguous so overweight and obese individuals rely on social norms to guide their eating behaviours to manage the impression others have of them. Therefore, it is expected that BMI will moderate the effects of social cues on snacking. More specifically it is hypothesised that BMI will moderate the effect of seeing others eating on snacking. When overweight and obese individuals lack a social reference their behaviour will reflect impulsivity eating behaviour. As such, it is also hypothesised that BMI will moderate the effect of being alone on Snacking. Over a 14-day period, 112 non-clinical individuals from the general population used Ecological Momentary Assessment (EMA) devices to record their eating behaviours and social surroundings in real-time. As hypothesised, BMI moderated the effects of social cues on snacking. Participants with a higher BMI were more likely to consume low-energy snacks when others were eating compared to participants with a lower BMI. Participants with a higher BMI were more likely to consume high-energy snacks when alone than participants with a lower BMI. This indicate that BMI moderates the relationship of social influences on snacking behaviour.

description: We consider the possible formation of the quark hadron mixed phase in protoneutron stars. We discuss two cases: the first one, corresponding to a vanishingly small value of the surface tension of quark matter, is the well known mixed phase in which the global electric charge neutrality condition is imposed. In turn, this produces a non-constant pressure mixed phase. In the second case, corresponding to very large values of the surface tension, the charge neutrality condition holds only locally. However, the existence in protoneutron star matter of an additional globally conserved charge, the lepton number, allows for a new type of non-constant pressure mixed phase. We discuss the properties of the new mixed phase and the possible effects of its formation during the evolution of protoneutron stars.

The design of the RF system for the TRIUMF cyclotron
Creators: name: Prochazka, Antonin
Publisher: name: University of British Columbia
Year: 2013

description: The basic design of the resonator system, coupling loop assembly and the resonant transmission line for the TRIUMF isochronous cyclotron is studied in detail and the beam-resonator RF field interaction is estimated using a simple model. The matching techniques which will allow a maximum power transfer from the power tube stage to the Dees are discussed. Two major computer programs have been written and are used to determine the parameters of the RF system necessary in order to obtain a desired impedance match and to find the various resonant frequencies of the RF system. The results of a large number of experimental tests carried out in order to verify the resonator electrical characteristics, to investigate the resonator frequency tuning and the resonator mechanical construction around the centre post, and to apply the proposed matching technique to the TRIUMF RF system, are given. The results from the prototype resonator segments and the transmission line tested at high power both in air and under high vacuum indicate that the RF system performance is compatible with the cyclotron operation.

description: We show at one-loop and first order in the noncommutativity parameters that in any noncommutative GUT inspired theory the total contribution to the fermionic four point functions coming only from the interaction between fermions and gauge bosons, though not UV finite by power counting, is UV finite at the end of the day. We also show that this is at odds with the general case for noncommutative gauge theories --chiral or otherwise-- defined by means of Seiberg-Witten maps that are the same --barring the gauge group representation-- for left-handed spinors as for right-handed spinors. We believe that the results presented in this paper tilt the scales to the side of noncommutative GUTS and noncommutative GUT inspired versions of the Standard Model.

description: The relativistic equilibrium velocity distribution plays a key role in describing several high-energy and astrophysical effects. Recently, computer simulations favored Juttner's as the relativistic generalization of Maxwell's distribution for d=1,2,3 spatial dimensions and pointed to an invariant temperature. In this work we argue an invariant temperature naturally follows from manifest covariance. We present a new derivation of the manifestly covariant Juttner's distribution and Equipartition Theorem. The standard procedure to get the equilibrium distribution as a solution of the relativistic Boltzmann's equation is here adopted. However, contrary to previous analysis, we use cartesian coordinates in d+1 momentum space, with d spatial components. The use of the multiplication theorem of Bessel functions turns crucial to regain the known invariant form of Juttner's distribution. Since equilibrium kinetic theory results should agree with thermodynamics in the comoving frame to the gas the covariant pseudo-norm of a vector entering the distribution can be identified with the reciprocal of temperature in such comoving frame. Then by combining the covariant statistical moments of Juttner's distribution a novel form of the Equipartition Theorem is advanced which also accommodates the invariant comoving temperature and it contains, as a particular case, a previous not manifestly covariant form.

Multi-String Theories, Massive Gravity and the AdS/CFT Correspondence

description: Infrared modifications of gravity have been proposed over the years as potentially useful phenomenological models. Massive (multi)-gravity is an interesting class of such theories. The true nature and the ultimate consistency of many of these models remains, however, unclear as one is frequently faced with important problems, e.g. classical instabilities and strong coupling problems which are hard to resolve without a known UV completion of the theory. In this note, we review a recent attempt to study some of these well known problems with the use of the AdS/CFT correspondence. In this context, products of large-N conformal field theories coupled by multi-trace interactions in diverse dimensions are used to define quantum multi-gravity (multi-string/M theory) on a union of (asymptotically) AdS spaces. One-loop effects generate a small O(1/N) mass for the gravitons and provide non-trivial examples of massive multi-graviton theories.

description: We study the non-perturbative dynamics of an unoriented Z_5-quiver theory of GUT kind with gauge group U(5) and chiral matter. At strong coupling the non-perturbative dynamics is described in terms of set of baryon/meson variables satisfying a quantum deformed constraint. We compute the effective superpotential of the theory and show that it admits a line of supersymmetric vacua and a phase where supersymmetry is dynamically broken via gaugino condensation.

Probabilistic risk-based operation planning for wind integrated power systems
Creators: name: Nguyen, DH
Publisher: name: University Of Tasmania
Year: 2023

description: Operation planning studies are essential in maintaining and operating a reliable and secure power system. They are based on existing system elements and aim to identify the operating limits within which reliability criteria are satisfied. Traditionally these studies are performed using deterministic criteria. It requires that a power system must be able to withstand an outage of any single component without violating any operating limits. However, it has been recognised that the deterministic method may no longer be adequate to deal with modern power systems with high level of renewable energy penetration. In particular, high variability and uncertainty of wind power generation may lead to significant load-generation imbalance resulting in large frequency deviations. This increases system operation risk, especially in small and isolated power systems which have low inertia and limited capabilities to provide frequency responses. Therefore, there is a need for investigating alternatives to current power system operation planning approaches to cope with the uncertain nature of the intermittent generation. This thesis proposes a novel probabilistic risk-based approach to evaluate power system security quantitatively in short-term (e.g., hour/s up to a day) operation planning with significant wind power generation in order to help facilitate day to day system operation. The proposed approach deals with steady-state voltage and overload evaluations as well as frequency deviation analysis. Load flow calculation techniques are used to perform the steady-state voltage and overload evaluations for post-disturbance system conditions. An analytical method to approximate frequency deviations is developed in order to assess the consequence of these frequency events without performing dynamic simulations. As a result, the frequency deviation analysis can be run simultaneously with the steady-state voltage and overload evaluations in the proposed risk assessment. The system operation risk is defined as the product of the probability and severity of system operating states in terms of expected load interruption cost. The risk calculation takes into account both the randomness of contingencies as well as the uncertainty of operating conditions caused by load and wind power generation forecast errors. The thesis also formulates a security constrained economic dispatch approach to determine operating reserve requirements in wind integrated power systems. This approach co-optimises operation risks resulted from inadequacy of system frequency responses and operation cost including energy price and cost of reserve provision. The effectiveness of the proposed approaches is illustrated by their application to a simplified model of Tasmanian power network, Australia under various system conditions and wind generation scenarios.
Electronic Structure, Magnetism and Superconductivity of Layered Iron Compounds

description: The layered iron superconductors are discussed using electronic structure calculations. The four families of compounds discovered so far, including Fe(Se,Te) have closely related electronic structures. The Fermi surface consists of disconnected hole and electron cylinders and additional hole sections that depend on the specific material. This places the materials in proximity to itinerant magnetism, both due to the high density of states and due to nesting. Comparison of density functional results and experiment provides strong evidence for itinerant spin fluctuations, which are discussed in relation to superconductivity. It is proposed that the intermediate phase between the structural transition and the SDW transition in the oxy-pnictides is a nematic phase.
