description: Carbon dioxide sequestration via mineral carbonation of steel slags combines two waste products to produce value-added products such as precipitated calcium carbonate (PCC). A systematic study of slag characterisation and its dissolution characteristics in acidic media has been carried out to understand leaching mechanism and model dissolution kinetics, to improve slag utilisation, and bring down the cost of carbon dioxide sequestration and PCC production. The thesis proposes an alternative to pH-Swing for impurity removal, demonstrates the existence of stable calcium carbonate supersaturation and non-passivating dissolution front during pressure-swing carbonation and establishes the role of RO phase sporulation on dissolution characteristics.
Analysis and improvement of low precision Hall-sensor-controlled brushless dc motors
Creators: name: Alaeinovin, Pooya
Publisher: name: University of British Columbia
Year: 2011

description: Hall-sensor-based Brushless dc (BLDC) motors are becoming very popular in wide range of applications, mainly due to their low cost, high efficiency, and reliable operation as compared to the conventional brushed motors. These machines have been extensively researched in the literature mainly under two common assumptions: each Hall-sensor produce square-wave signal of exactly 180 electrical degrees; and that the signals from the three Hall-sensors are exactly 120 electrical degrees apart. These assumptions are not necessarily the case, particularly for low to medium cost motors. A recently published manuscript investigated operation of motors with unbalanced Hall-sensor signals and introduced inaccurate positioning of the sensors as the cause of the unbalance. There, solutions have been proposed to mitigate the adverse effects of sensor positioning errors on performance of the motor. This thesis builds upon this recent publication by identifying another source of error in the Hall-sensor signals. Here, it is shown that inaccurate positioning of the Hall sensors and uneven magnetization of the tablet with which the Hall sensors react are the major factors contributing to the distortion of Hall sensor signals. It is shown here that errors in the Hall sensor signals result in unsymmetrical operation of the inverter which in turn leads to low-frequency harmonics in the electromagnetic torque; increases torque ripple and acoustic noise; and degrade overall dynamic performance of the drive. A control-level approach is proposed to mitigate the adverse effects of the errors in the Hall-sensor signals. In this approach a multi-stage digital filtering block is added to remove the errors in the original Hall-sensor signals. Each stage of the filter is designed to cancel the undesirable harmonics due to one of the error sources, the unevenly magnetized reaction tablet and the misaligned Hall sensors. An efficient realization of the proposed filter is presented that makes it possible to be potentially programmed inside existing motor controllers or implemented in a stand-alone microcontroller which can be packaged into a dongle circuit. The operation of typical low-precision industrial BLDC motors with the proposed filtering approach is shown to approach the performance of the motors with ideal Hall sensors.

description: In Dirac's canonical quantization theory on systems with second-class constraints, the commutators between the position, momentum and Hamiltonian form a set of algebraic relations that are fundamental in construction of both the quantum momentum and the Hamiltonian. For a free particle on a two-dimensional sphere or a spherical top, results show that the well-known canonical momentum p_{θ} breaks one of the relations, while three components of the momentum expressed in the three-dimensional Cartesian system of axes as p_{i} (i=1,2,3) are satisfactory all around. This momentum is not only geometrically invariant but also self-adjoint, and we call it geometric momentum. The nontrivial commutators between p_{i} generate three components of the orbital angular momentum; thus the geometric momentum is fundamental to the angular one. We note that there are five different forms of the geometric momentum proposed in the current literature, but only one of them turns out to be meaningful.

description: This thesis presents a comprehensive numerical study of the granular segregation in piling processes and vibrated systems. The research is carried with the help of a DEM model developed for ellipsoids. The simulation studies and associated analysis have elevated the triggering mechanisms of the segregation behavior to a new level where the observed segregation can be interpreted in both microscopic and macroscopic views. Furthermore, the adoption of ellipsoids largely demonstrates the effects of particle shape which significantly shortens the distance between scientific researches and real industrial issues.
Resonant motions in the presence of degeneracies for quasi-periodically perturbed systems

description: We consider one-dimensional systems in the presence of a quasi-periodic perturbation, in the analytical setting, and study the problem of existence of quasi-periodic solutions which are resonant with the frequency vector of the perturbation. We assume that the unperturbed system is locally integrable and anisochronous, and that the frequency vector of the perturbation satisfies the Bryuno condition. Existence of resonant solutions is related to the zeroes of a suitable function, called the Melnikov function - by analogy with the periodic case. We show that, if the Melnikov function has a zero of odd order and under some further condition on the sign of the perturbation parameter, then there exists at least one resonant solution which continues an unperturbed solution. If the Melnikov function is identically zero then one can push perturbation theory up to the order where a counterpart of Melnikov function appears and does not vanish identically: if such a function has a zero of odd order and a suitable positiveness condition is met, again the same persistence result is obtained. If the system is Hamiltonian, then the procedure can be indefinitely iterated and no positiveness condition must be required: as a byproduct, the result follows that at least one resonant quasi-periodic solution always exists with no assumption on the perturbation. Such a solution can be interpreted as a (parabolic) lower-dimensional torus.

description: This thesis is to upgrade low-rank coal to high-quality thermal fuel that can be burnt at high-efficiency and low-emission for power generation, via leaching out the troublesome alkali and alkaline earth metals to reduce its fouling propensity.

description: We introduce a general technique to compute finite temperature electronic properties by a novel covariant formulation of the electronic partition function. By using a rigorous variational upper bound to the free energy we are led to the evaluation of a partition function that can be computed stochastically by sampling electronic wave functions and atomic positions (assumed classical). In order to achieve this target we show that it is extremely important to consider the non trivial geometry of the space defined by the wave function ansatz. The method can be extended to any technique capable to provide an energy value over a given wave function ansatz depending on several variational parameters and atomic positions. In particular we can take into account electronic correlation, by using the standard variational quantum Monte Carlo method, that has been so far limited to zero temperature ground state properties. We show that our approximation reduces correctly to the standard Born-Oppenheimer (BO) one at zero temperature and to the correct high temperature limit. At large enough temperatures this method allows to improve the BO, providing lower values of the electronic free energy, because within this method it is possible to take into account the electron entropy. We test this new method on the simple hydrogen molecule, where at low temperature we recover the correct BO low temperature limit. Moreover, we show that the dissociation of the molecule is possible at a temperature much smaller than the BO prediction. Several extension of the proposed technique are also discussed, as for instance the calculation of critical (magnetic, superconducting) temperatures, or transition rates in chemical reactions.
Exploration of the Barriers and Enablers of Mainstream Classroom Teachers Accessing Professional Development on Trauma Informed Classroom Pedagogy: The Nativity of the Embrace Framework

description: Over the past decade, considerable focus has been on the classroom and disciplinary responses that disproportionately affect students enduring adversity and disadvantage. A considerable body of research exists that supports the relational approach of trauma informed practice to mitigate the effects of risk factors in the lives of children with developmental trauma. It is an area that emphasises the interpersonal skills of adults rather than focusing on the knowledge and behavioural skills of the child. As part of an Exploratory Sequential Mixed Methods research project, this project explores the barriers and enablers for mainstream classroom teachers engaging in professional development. This exegesis discusses the methodology, rationale, and results for this research project through examining the qualitative research process undertaken with a group of sixteen mainstream primary school teachers through semi-structured interviews. This is followed by a quantitative study consisting of a forty-item online survey with 300 teachers to determine if the results from the qualitative study can be attributed to a wider population. This research project is a thesis by publication with two of three articles published and the third paper submitted and under review by the journal at the time of submission of this exegesis. These results are consistent with the literature and highlight the problem being greater than single classroom teacher practice and possibly are amendable with policymakers and leadership staff making changes to practice, policies, and frameworks at a sector and school level. These results have significant implications for future framework implementation in school settings and the researcher has contributed to practice and knowledge in the sector through the development of a framework titled, 'The Embrace Framework' that is informed by the findings from this research project.

description: The ironmaking blast furnace is a complex high temperature, high pressure, multiphase flow reactor with an inner volume of up to 6000 m3, used to produce raw and molten iron, also known as pig iron. This research explores the interaction of the granular material inside a blast furnace, namely iron ore and coke, with its internal stave coolers, which are attached to the blast furnace’s inner walls. The descent of the ore and coke particles is modelled by computational methods and scaled cold blast furnace experiments, from which information about the flow structure and particle-wall interaction forces is obtained.

description: It is known that the anomalous Hall conductivity (AHC) in a disordered two dimensional electron system with Rashba spin-orbit interaction and finite ferromagnetic spin-exchange energy is zero in the metallic weak-scattering regime because of the exact cancellation of the bare-bubble contribution by the vertex correction. We study the effect of inhomogeneous longitudinal electric field on the AHC in such a system. We predict that AHC increases from zero (at zero wavenumber), forms a peak, and then decreases as the wavenumber for the variation of electric field increases. The peak-value of AHC is as high as the bare-buble contribution. We find that the wave number, q, at which the peaks occur is the inverse of the geometric mean of the mean free path of an electron and the spin-exchange length scale. Although the Rashba energy is responsible for the peak-value of AHC, the peak position is independent of it.

description: Detection and monitoring of proteins and metabolites in tissues, organs and blood represents a grand challenge in the field of sensing, because blood sampling does not necessarily reflect tissue biochemistry. The development of responsive nanomaterials that retain stability and function in biological environments is therefore an area of significant importance.

description: We report on an extensive structural and electrical characterization of under-gate dielectric oxide insulators Al2O3 and HfO2 grown by Atomic Layer Deposition (ALD). We elaborate the ALD growth window for these oxides, finding that the 40-100 nm thick layers of both oxides exhibit fine surface flatness and required amorphous structure. These layers constitute a base for further metallic gate evaporation to complete the Metal-Insulator-Semiconductor structure. Our best devices survive energizing up to ~3 MV/cm at 77 K with the leakage current staying below the state-of-the-art level of 1 nA. At these conditions the displaced charge corresponds to a change of the sheet carrier density of 3 \times 1013 cm-2, what promises an effective modulation of the micromagnetic properties in diluted ferromagnetic semiconductors.

description: Realistic methods to create vortices in spin-orbit-coupled Bose-Einstein condensates are discussed. It is shown that, contrary to common intuition, rotation of the trap containing a spin-orbit condensate does not lead to an equilibrium state with static vortex structures, but gives rise instead to non-equilibrium behavior described by an intrinsically time-dependent Hamiltonian. We propose here the following alternative methods to induce thermodynamically stable static vortex configurations: (1) to rotate both the lasers and the anisotropic trap; and (2) to impose a synthetic Abelian field on top of synthetic spin-orbit interactions. Effective Hamiltonians for spin-orbit condensates under such perturbations are derived for most currently known realistic laser schemes that induce synthetic spin-orbit couplings. The Gross-Pitaevskii equation is solved for several experimentally relevant regimes. The new interesting effects include spatial separation of left- and right-moving spin-orbit condensates, the appearance of unusual vortex arrangements, and parity effects in vortex nucleation where the topological excitations are predicted to appear in pairs. All these phenomena are shown to be highly non-universal and depend strongly on a specific laser scheme and system parameters.

Mach like principle from conserved charges

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study models where the gauge coupling constants, masses and the gravitational constant are functions of some conserved charge in the universe, and furthermore a cosmological constant that depends on the total charge of the universe. We first consider the standard Dirac action, but where the mass and the electromagnetic coupling constant are a function of the charge in the universe and afterwards extend this to curved spacetime and consider gauge coupling constants, the gravitation constant and the mass as a function of the charge of the universe, which represent a sort of Mach principle for all the constants of nature. In the flat space formulation, the formalism is not manifestly Lorentz invariant, however Lorentz invariance can be restored by performing a phase transformation of the Dirac field, while in the curved space time formulation, there is the additional feature that some of the equations of motion break the general coordinate invariance also, but in a way that can be understood as a coordinate choice only, so the equations are still of the General Relativity type, but with a certain natural coordinate choice, where there is no current of the charge. We have generalized what we have done and also constructed a cosmological constant which depends on the total charge of the universe. If we were to use some only approximately conserved charge for these constructions, like say baryon number (in the context of the standard model), this will lead to corresponding violations of Lorentz symmetry in the early universe for example. The construction of charge dependent contributions can also be motivated from the structure of the "infra-red counter terms" needed to cancel infra red divergences for example in three dimensions.

description: Previous studies have demonstrated that gravitational radiation reliably encodes information about the natural emission direction of the source (e.g., the orbital plane). In this paper, we demonstrate that these orientations can be efficiently estimated by the principal axes of , an average of the action of rotation group generators on the Weyl tensor at asymptotic infinity. Evaluating this average at each time provides the instantaneous emission direction. Further averaging across the entire signal yields an average orientation, closely connected to the angular components of the Fisher matrix. The latter direction is well-suited to data analysis and parameter estimation when the instantaneous emission direction evolves significantly. Finally, in the time domain, the average provides fast, invariant diagnostics of waveform quality.

description: We generalize the SU(N=2) $S=1/2$ square-lattice quantum magnet with nearest-neighbor antiferromagnetic coupling ($J_1$) and next-nearest-neighbor ferromagnetic coupling ($J_2$) to arbitrary $N$. For all $N>4$, the ground state has valence-bond-solid (VBS) order for $J_2=0$ and Néel order for $J_2/J_1\gg 1$, allowing us access to the transition between these types of states for large $N$. Using quantum Monte Carlo simulations, we show that both order parameters vanish at a single quantum-critical point, whose universal exponents for large enough $N$ (here up to N=12) approach the values obtained in a 1/N expansion of the non-compact CP$^{N-1}$ field theory. These results lend strong support to the deconfined quantum-criticality theory of the Néel--VBS transition.

description: The increasing level of pollution by the presence of particulates and bacteria leads to respiratory diseases such as asthma, characterised by inflammation and difficulty in breathing. Current treatments with corticosteroids and anti-inflammatories like statins are ineffective due to adverse effects such as increased blood pressure, chest pain and obesity to name a few. We demonstrated for the first time, the role of amino acid (glycine) as an anti-inflammatory agent, capable of reducing lung inflammation and improving lung function. The ultrafine glycine-coated particles can be encapsulated in larger glycine microspheres for delivery via dry powder inhaler for therapeutic use.

While for z/-z asymmetric SO coupling, disordered graphene should display a weak anti-localization behavior at lowest temperature, z/-z symmetric coupling leads to an effective saturation of decoherence time which can be partially lifted by an in-plane magnetic field, thus, tending to restore the weak localization effect.

description: Mild steel is the most widely employed engineering alloy and the annual direct cost of corrosion of this alloy to an industrialised economy to be approximately 3.1% of the country's Gross National Product (GNP). Due to its extraordinary chemical inertness and impermeability, graphene can be an ideal candidate material for anti-corrosion coating on mild steel. This thesis deals with the challenges of depositing graphene on mild steel by chemical vapour deposition (CVD) and improved the corrosion resistance of this alloy more than 100 times by successfully coating modified mild steel surface by multilayer graphene.

description: We discuss laser dressed dipolar and Van der Waals interactions between atoms and polar molecules, so that a cold atomic gas with laser admixed Rydberg levels acts as a designed reservoir for both elastic and inelastic collisional processes. The elastic scattering channel is characterized by large elastic scattering cross sections and repulsive shields to protect from close encounter collisions. In addition, we discuss a dissipative (inelastic) collision where a spontaneously emitted photon carries away (kinetic) energy of the collision partners, thus providing a significant energy loss in a single collision. This leads to the scenario of rapid thermalization and cooling of a molecule in the mK down to the μK regime by cold atoms.

On optimum parameter modulation-estimation from a large deviations perspective
Creators: name: Merhav, Neri
Publisher: name: arXiv
Year: 2012
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: We consider the problem of jointly optimum modulation and estimation of a real-valued random parameter, conveyed over an additive white Gaussian noise (AWGN) channel, where the performance metric is the large deviations behavior of the estimator, namely, the exponential decay rate (as a function of the observation time) of the probability that the estimation error would exceed a certain threshold. Our basic result is in providing an exact characterization of the fastest achievable exponential decay rate, among all possible modulator-estimator (transmitter-receiver) pairs, where the modulator is limited only in the signal power, but not in bandwidth. This exponential rate turns out to be given by the reliability function of the AWGN channel. We also discuss several ways to achieve this optimum performance, and one of them is based on quantization of the parameter, followed by optimum channel coding and modulation, which gives rise to a separation-based transmitter, if one views this setting from the perspective of joint source-channel coding. This is in spite of the fact that, in general, when error exponents are considered, the source-channel separation theorem does not hold true. We also discuss several observations, modifications and extensions of this result in several directions, including other channels, and the case of multidimensional parameter vectors. One of our findings concerning the latter, is that there is an abrupt threshold effect in the dimensionality of the parameter vector: below a certain critical dimension, the probability of excess estimation error may still decay exponentially, but beyond this value, it must converge to unity.

description: We present a novel nonparametric Bayesian approach based on Lévy Adaptive Regression Kernels (LARK) to model spectral data arising from MALDI-TOF (Matrix Assisted Laser Desorption Ionization Time-of-Flight) mass spectrometry. This model-based approach provides identification and quantification of proteins through model parameters that are directly interpretable as the number of proteins, mass and abundance of proteins and peak resolution, while having the ability to adapt to unknown smoothness as in wavelet based methods. Informative prior distributions on resolution are key to distinguishing true peaks from background noise and resolving broad peaks into individual peaks for multiple protein species. Posterior distributions are obtained using a reversible jump Markov chain Monte Carlo algorithm and provide inference about the number of peaks (proteins), their masses and abundance. We show through simulation studies that the procedure has desirable true-positive and false-discovery rates. Finally, we illustrate the method on five example spectra: a blank spectrum, a spectrum with only the matrix of a low-molecular-weight substance used to embed target proteins, a spectrum with known proteins, and a single spectrum and average of ten spectra from an individual lung cancer patient.

description: As a class of reactions, the liquid phase oxidation of hydrocarbons is a major source of many organic chemicals and plays a significant role in the modern petrochemical industry. The liquid phase oxidation of cyclohexane is a typical member of this class of reactions. As the products of this reaction, cyclohexanol and cyclohexanone which are in turn processed into caprolactam and adipic acid supply the main raw materials for the manufacture of Nylon-6 and Nylon-66. The primary intermediate of cyclohexane oxidation, cyclohexyl hydroperoxide, also has special industrial importance since it can produce other products with good selectivity under mild conditions. However, the oxidation of cyclohexane is relatively a difficult process and is plagued by the problem of selectivity since the desired products, i.e. cyclohexyl hydroperoxide, cyclohexanol and cyclohexanone, are intermediates in a sequence of reactions and overoxidation results easily in a number of useless by-products. A study of the kinetic mechanism of cyclohexane oxidation is therefore significant for the development of new technologies and the improvement of existing processes.

description: Fast fluidized bed is widely used in coal combustion and gasification, fluid catalytic cracking and Fischer-Tropsch synthesis due to its high efficiency in gas-solid reaction, heat and mass transfer. This study focuses on the investigation of cluster behavior in fast fluidised bed through both experimental and numerical simulation approaches, aiming to better understand the dynamics of the fast fluidised bed in a meso-scale and the repercussions of their behavior for the overall system efficiency.

description: Lifetime maximization is a key challenge in the design of sensor-network-based tracking applications. In this dissertation, formation of optimal coalitions of nodes is investigated for data acquisition in bearings-only target localization such that the average sleep times allocated to the nodes are maximized. Targets are assumed to be localized with a pre-defined accuracy where the determinant of the Bayesian Fisher information matrix (B-FIM) is used as the metric for estimation accuracy. Cooperative game theory is utilized as a tool to devise a distributed dynamic coalition formation algorithm in which nodes autonomously decide which coalition to join, while maximizing their feasible sleep times. Nodes in the sleep mode do not record any measurements; hence, save power in both sensing and transmitting the sensed data. The proposed scheme reduces the number of sensor measurements by capturing the spatio-temporal correlation of the information provided by the sensors from one side and bounding the localization accuracy to the pre-defined value from the other side. It is proved that if each node operates according to this algorithm, the average sleep time for the entire network converges to its maximum feasible value. In numerical examples, we illustrate the inherent trade-off between the localization accuracy and the average sleep time allocated to the nodes and demonstrate the superior performance of the proposed algorithm via Monte Carlo simulations.

Creators: name: Wendy, Thomas
Publisher: name: Zenodo
Year: 2023

description: The vision of DDI has grown over the years from a simple codebook for microdata and aggregate data files, to a model that supported metadata-driven data systems, to a suite of products that supports a variety of applications in a broad area of coverage across several related disciplines. This shift in focus reflects changes in the data environment, technology, and user needs over time. It raises the need for a clear road-map for individual products as well as the overall integration of DDI products and support mechanisms. The Technical Committee of the DDI is responsible for overseeing the coordinated development, publication, and maintenance of the suite of DDI products. As such, the overall roadmap needs to reflect the intended purpose and means of ensuring the development and maintenance of a well-integrated suite of products as well as products to support product development and the smooth transfer of metadata between products to support different applications and uses over time. This presentation will address activities and plans to address issues concerning:- The integration and interplay of products in the DDI Suite- Common ontology/common objects used across DDI products- Movement of content between products- Product alignment in terms of coverage and applied usage- Consistency f new coverage areas in multiple products- Tooling to support input to the development process, transfer of content between products, and decision support

description: Biomass conversion to green platform chemicals like levoglucosenone and 5-chloromethyl furfural (5-CMF) is conducive to a sustainable future. This is the first study to demonstrate one-step conversion of biomass to levoglucosenone and 5-CMF in a scalable fluidised bed reactor technology. First, biomass was characterised and a laboratory scale fluidised bed reactor was designed and commissioned for thermo-catalytic process development. Next, a suitable catalyst was used for biomass conversion to chemicals. Critical process parameters were optimized to obtain high yield and selectivity. Finally, the thermo-catalytic reaction mechanism was investigated through synchrotron-based infra-red spectroscopy.
Kinetically-Enhanced Anomaly Mediation

description: We investigate a modification of anomaly-mediated supersymmetry breaking (AMSB) with an exotic U(1)_x gauge sector that can solve the tachyonic slepton problem of minimal AMSB scenarios. The new U(1)_x multiplet is assumed to couple directly to the source of supersymmetry breaking, but only indirectly to the minimal supersymmetric Standard Model (MSSM) through kinetic mixing with hypercharge. If the MSSM sector is also sequestered from the source of supersymmetry breaking, the contributions to the MSSM soft terms come from both AMSB and the U(1)_x kinetic coupling. We find that this arrangement can give rise to a flavour-universal, phenomenologically viable, and distinctive spectrum of MSSM superpartners. We also investigate the prospects for discovery and the most likely signatures of this scenario at the Large Hadron Collider (LHC).

description: This PhD thesis focuses on development of cellulose fibre composite depth filters with improved functionalities. Depth filters are widely used in industrial food and pharmaceutical purification processes. However, there is still need for improvement of the existing filter products. Also, they should be explored more and adapted to different applications. In the first part, depth filters were critically analysed to explore and extend the range of properties achievable by different components. Then, new advanced filter structures were engineered to improve the performance. In the last section, biodegradable and renewable cellulose nanofibres were used to develop cleaner filters for food grade applications.

description: This deliverable addresses the complex interactions of innovation, exploitation and interoperability in IPERION HS and their contributions to E-RIHS. It is based on work carried out in T6.1 (Innovation), T6.3 (Interoperability) and T6.4 (Exploitation) and draws heavily on the interim deliverables produced by those Tasks. The information was obtained by carrying out surveys, interviews, examination of previous publications and by the development of a data management plan. The work was carried out to support IPERION HS, but here we also examine the implications for E-RIHS ERIC. The main conclusion is that Heritage Science and E-RIHS exists within its own ecosystem, but to maximise its impact, it needs to engage with a wide range of other, related interests. This involves engaging with new user groups and collaborating with companies as well as recognising innovative training and outreach efforts, and ensuring that data is acquired and stored in a way that allows it to be shared with other users. As the visibility of Heritage Science increases, new user communities may arise, and significant government spending departments such as defence, healthcare, transport, and international development may start showing interest in Heritage Science. E-RIHS needs to be ready to respond to these changes, as well as to evolving international legislation and best practices in open data, open science, and intellectual property by updating policies frequently. Heritage Science needs to seek out new developments in other areas of science, technology, and industry that could have applications in Heritage Science. Similarly, the Heritage Science community needs to work with industry to exploit developments made in Heritage Science for maximum impact. The broad range of technologies, datatypes, and manufacturers found in Heritage Science makes open and FAIR data particularly challenging. E-RIHS can guide the Heritage Science community in developing a shared understanding of open data, which could contribute significantly to broader areas of science.

description: In the context of this special issue's inquiry into whether it is possible to decolonise Australian international relations, this article investigates the service of Indigenous people in the Australian Defence Force (ADF). The military is a crucial site to investigate the colonial state of Australian international relations not only because it is an institution that performs key international relations practices such as war and diplomacy, but also because it defines and projects the identity of the state both domestically and internationally. In the past two decades, there has been a sustained effort to include Indigenous people in the ADF. An inclusive and multicultural defence purports to represent a post-colonial state where Indigenous and non-Indigenous people stand next to one another for the defence of their shared country. However, in Australia, Indigenous people do not enjoy the wealth of the nation equally and remain dispossessed from their land and economically disadvantaged. Using discourse analysis of publicly available materials praising Indigenous military inclusion, this article argues that the inclusion of Indigenous people in the Australian Defence Force risks further entrenching the settler colonial project.
