description: Purpose. To obtain the interference immunity of the data exchange by spread spectrum signals with variable entropy of the telemetric information data exchange with autonomous mobile robots.
 Methodology. The results have been obtained by the theoretical investigations and have been confirmed by the modeling experiments.
 Findings. The interference immunity in form of dependence of bit error probability on normalized signal/noise ratio of the data exchange by spread spectrum signals with variable entropy has been obtained.It has been proved that the interference immunity factor (needed normalized signal/noise ratio) is at least 2 dB better under condition of equal time complexity as compared with correlation processing methods of orthogonal signals.
 Originality. For the first time the interference immunity in form of dependence of bit error probability on normalized signal/noise ratio of the data exchange by spread spectrum signals with variable entropy has been obtained.
 Practical value. The obtained results prove the feasibility of using variable entropy spread spectrum signals data exchange method in the distributed telemetric information processing systems in specific circumstances.

description: We define a two-dimensional space called the spinor-plane, where all spinors that can be decomposed in terms of Restricted Inomata-McKinley (RIM) spinors reside, and describe some of its properties. Some interesting results concerning the construction of RIM-decomposable spinors emerge when we look at them by means of their spinor-plane representations. We show that, in particular, this space accomodates a bijective linear map between mass-dimension-one and Dirac spinor fields. As a highlight result, the spinor-plane enables us to construct homotopic equivalence relations, revealing an algebraic-topological link between these spinors. In the end, we develop a simple method that provides the categorization of RIM-decomposable spinors in the Lounesto classification, working by means of spinor-plane coordinates, which avoids the often hard work of analising the bilinear covariant structures one by one.

description: Background: In many high-income countries, COVID-19 has disproportionately impacted Culturally and Linguistically Diverse (CALD) communities. Barriers to engaging with essential health messaging has contributed to difficulties in following public health advice and exacerbated existing inequity in Australia. Research suggests that recently-arrived CALD populations are particularly vulnerable to misinformation and are more likely to experience vaccine hesitancy. The aim of this study was to explore the barriers and enablers to COVID-19 vaccination among recently-arrived CALD communities in Melbourne’s outer north and identify strategies to reduce hesitancy in this population. Methods: Semi-structured interviews were conducted with representatives from community organisations working with recently-arrived CALD communities in Melbourne’s north. This included a mix of peer (from the community) and health care workers. Results: Fifteen participants from community organisations participated in interviews. Thematic analysis identified four themes; (1) trusted sources, (2) accurate and culturally sensitive information, (3) supported pathways and (4) enablers to vaccination. Conclusions: Participants reported a perceived lack of accurate, culturally sensitive health information and service provision as key barriers to vaccination in recently-arrived CALD communities. Participants identified a range of perceived enablers to increasing vaccination uptake in the communities they work with, including utilising established channels of communication and harnessing the communities’ strong sense of collective responsibility. Specific strategies to reduce vaccine hesitancy included identifying and utilising trusted sources (e.g. faith leaders) to disseminate information, tailoring health messages to address cultural differences, providing opportunities to contextualise information, and modifying service delivery to enhance cultural sensitivity. There is an urgent need for increased efforts from health and government agencies to build sustainable, collaborative relationships with CALD communities.

description: Pressure oscillations at small time steps have been known to be an issue in poroelasticity simulations. A review of proposed approaches to overcome this problem is presented. Critical time steps are specified to alleviate this in finite element analyses. We present a mixed isogeometric formulation here with a view to assessing the results at very small time steps. Numerical studies are performed on Terzaghi's problem and consolidation of a layered porous medium with a very low permeability layer for varying polynomial degrees, continuities across knot spans and spatial discretizations. Comparisons are made with equal order simulations.

description: A new class of disk MHD equilibrium solutions is described, which is valid within the standard local (``shearing sheet'') approximation scheme. These solutions have the following remarkable property: velocity streamlines and magnetic lines of force rotate rigidly, even in the presence of differential rotation. This situation comes about because the Lorentz forces acting upon modified epicycles compel fluid elements to follow magnetic lines of force. Field line (and streamline) configurations may be elliptical or hyperbolic, prograde or retrograde. These structures have previously known hydrodynamical analogs: the ``planet'' solutions described by Goodman, Narayan, & Goldreich. The primary focus of this investigation is configurations in the disk plane. A related family of solutions lying in a vertical plane is briefly discussed; other families of solutions may exist. Whether these MHD structures are stable is not yet known, but could readily be determined by three-dimensional simulations. If stable or quasi-stable, these simple structures may find important applications in both accretion and galactic disks.

description: Despite rapid growth of mega-projects, they still suffer from failure in a range of critical management areas, including significant cost and time overrun. A major reason for this failure is a lack of good planning and management of the project scope, which was the focus of the research discussed in this thesis. An extensive literature review confirmed that the process of planning and managing project scope management in transport mega-projects was not well executed. As a result, these projects suffered from significant problems of escalation in the cost and time of their execution. Qualitative approach methods, case study strategy, and interviews with higher management members were subsequently specifically designed and applied for the collection of data that would achieve the objectives and aims of this research. The key findings of the study were that a number of factors affected the accuracy of the project scope planning process for Australian transport mega-projects, especially misdefinition of the project scope, unclarity of the sponsor requirements, poor business case, poor design process, deficiencies in the planning process, assumptions, lack of expertise staff, and insufficient scope document. The main implication of the study's findings was that a lack in the project scope planning process was the major factor that impacted cost and time overruns, scope change, deficiencies in the cost and time estimates, execution risks, and conflicts among project stakeholders. Thus, there is a need to improve these processes in order to avoid or mitigate similar pitfalls in the future. So, the main aim of the research study was to design and develop an improved framework for the project scope planning management process and recommend it for the future. Therefore, the findings of this study provided the basis for developing a new process for transport mega-project scope planning.
Multilevel optimisation for computer vision
Creators: name: Hovhannisyan, Vahan
Publisher: name: Imperial College London
Year: 2017

description: The recent spark in machine learning and computer vision methods requiring increasingly larger datasets has motivated the introduction of optimisation algorithms specifically tailored to solve very large problems within practical time constraints. This demand in algorithms challenges the practicability of state of the art methods requiring new approaches that can take advantage of not only the problem’s mathematical structure, but also its data structure. Fortunately, such structure is present in many computer vision applications, where the problems can be modelled with varying degrees of fidelity. This structure suggests using multiscale models and thus multilevel algorithms. The objective of this thesis is to develop, implement and test provably convergent multilevel optimisation algorithms for convex composite optimisation problems in general and its applications in computer vision in particular. Our first multilevel algorithm solves convex composite optimisation problem and it is most efficient particularly for the robust facial recognition task. The method uses concepts from proximal gradient, mirror descent and multilevel optimisation algorithms, thus we call it multilevel accelerated gradient mirror descent algorithm (MAGMA). We first show that MAGMA has the same theoretical convergence rate as the state of the art first order methods and has much lower per iteration complexity. Then we demonstrate its practical advantage on many facial recognition problems. The second part of the thesis introduces new multilevel procedure most appropriate for the robust PCA problems requiring iterative SVD computations. We propose to exploit the multiscale structure present in these problems by constructing lower dimensional matrices and use its singular values for each iteration of the optimisation procedure. We implement this approach on three different optimisation algorithms - inexact ALM, Frank-Wolfe Thresholding and non-convex alternating projections. In this case as well we show that these multilevel algorithms converge (to an exact or approximate) solution with the same convergence rate as their standard counterparts and test all three methods on numerous synthetic and real life problems demonstrating that the multilevel algorithms are not only much faster, but also solve problems that often cannot be solved by their standard counterparts.

description: We introduce the $B$-spline interpolation problem corresponding to a $C^*$-valued sesquilinear form on a Hilbert $C^*$-module and study its basic properties as well as the uniqueness of solution. We first study the problem in the case when the Hilbert $C^*$-module is self-dual. Extending a bounded $C^*$-valued sesquilinear form on a Hilbert $C^*$-module to a sesquilinear form on its second dual, we then provide some necessary and sufficient conditions for the $B$-spline interpolation problem to have a solution. Passing to the setting of Hilbert $W^*$-modules, we present our main result by characterizing when the spline interpolation problem for the extended $C^*$-valued sesquilinear to the dual $\mathscr{X}'$ of the Hilbert $W^*$-module $\mathscr{X}$ has a solution. As a consequence, we give a sufficient condition that for an orthogonally complemented submodule of a self-dual Hilbert $W^*$-module $\mathscr{X}$ is orthogonally complemented with respect to another $C^*$-inner product on $\mathscr{X}$. Finally, solutions of the $B$-spline interpolation problem for Hilbert $C^*$-modules over $C^*$-ideals of $W^*$-algebras are extensively discussed. Several examples are provided to illustrate the existence or lack of a solution for the problem.

description: Peres and Solomyak asked the question: Do there exist self-similar sets with positive Lebesgue measure and empty interior? This question was answered in the affirmative by Csörnyei et al. They gave a parameterised family of iterated function systems for which almost all of the corresponding self-similar sets satisfied the required properties. They do not however provide an explicit example. Motivated by a desire to construct an explicit example, we in this paper provide an explicit construction of an infinitely generated self-similar set with positive Lebesgue measure and empty interior.
Characterisation of the pathogenic Escherichia coli type three secretion system effector NleG
Creators: name: McGeever, Bevin
Publisher: name: Imperial College London
Year: 2016

description: Enteropathogenic and enterohaemorrhagic E. coli are widely prevalent as the causative agents of diarrhoeal disease globally. Pathogenesis is mediated by injection of effector proteins by a Type III Secretion System (T3SS) into the cytosol of host cells. Recently bioinformatics and secretome analysis has been used to expand the repertoire of effectors to include several novel T3SS secreted bacterial proteins. The largest family among these is the NleG family, with nine members in enterohaemorrhagic E. coli O157:H7 strain EDL933 alone. While there is significant sequence diversity between family members, conserved catalytic residues in the C terminus show structural homology to E3 ubiquitin ligases. Ubiquitination is the covalent attachment of ubiquitin to target proteins to label them for degradation, signalling, trafficking and regulation of DNA transcription. Several viruses and bacteria encode ubiquitin modulating enzymes to manipulate the host cell during infection. Currently there are no known targets for NleG. This study identifies host interacting partners for the NleG family through yeast two hybrid screening. An interaction between NleG and DDX60, a DNA helicase implicated in the innate immune response, and a distinct interaction with a key cell cycle regulator, CDC20, are investigated further.

description: Due to the efforts of Governor Davis, an act was passed by the [Texas] state legislature on July 1, 1870, creating a state police force. This body of men was composed of a chief, four captains, eight lieutenants, twenty sergeants, and two hundred and twenty-five privates. The state police were, in their actions, under the absolute control of the governor and could be dismissed by him at any time. They were to work in conjunction with the state militia. Incorporated as a part of the state police system were the local peace officers; these included the sheriffs, constables, city marshals, and local police. However, the state police could work independently of the local peace officers wherever it was necessary. As provided by the state police act, the adjutant general was to serve as chief of the organization. Consequently, Adjutant General James Davidson became chief of state police. [...] During 1871, an amendment to the state police act was passed which provided that the force should be made up of six captains, twelve lieutenants, thirty sergeants and two hundred and ten privates. The salaries of the policemen were increased, and they were to be allowed the same compensation for mileage as was permitted to sheriffs. The act further provided that the governor could create special policemen wherever necessary, but they were not to exceed twenty in number; the governor might also constitute baggage masters and conductors on railroads to act as special police. [...] In January of 1873, with a majority of Democrats in the legislature, the state police was doomed and on April 22, the measure creating the institution was repealed

description: We have performed a series of high resolution N-body experiments on a Connection Machine CM-5 in order to study the stability of collisionless self-gravitating spherical systems. We interpret our results in the framework of symplectic mechanics, which provides the definition of a new class of particular perturbations: The preserving perturbations, which are a generalization of the radial ones. Using models defined by the Ossipkov-Merritt algorithm, we show that the stability of a spherical anisotropic system is directly related to the preserving or non-preserving nature of the perturbations acting on the system. We then generalize our results to all spherical systems. Since the ``isotropic component'' of the linear variation of the distribution function cannot be used to predict the stability or instability of a spherical system, we propose a more useful stability parameter which is derived from the ``anisotropic'' component of the linear variation.

description: Neural networks with physical governing equations as constraints have recently created a new trend in machine learning research. In line with such efforts, a deep learning model for one-dimensional consolidation where the governing equation is applied as a constraint in the neural network is presented here. A review of related research is first presented and discussed. The deep learning model relies on automatic differentiation for applying the governing equation as a constraint. The total loss is measured as a combination of the training loss (based on analytical and model predicted solutions) and the constraint loss (a requirement to satisfy the governing equation). Two classes of problems are considered: forward and inverse problems. The forward problems demonstrate the performance of a physically constrained neural network model in predicting solutions for one-dimensional consolidation problems. Inverse problems show prediction of the coefficient of consolidation. Terzaghi's problem with varying boundary conditions are used as example and the deep learning model shows a remarkable performance in both the forward and inverse problems. While the application demonstrated here is a simple one-dimensional consolidation problem, such a deep learning model integrated with a physical law has huge implications for use in, such as, faster real-time numerical prediction for digital twins, numerical model reproducibility and constitutive model parameter optimization.

The Disk-Magnetosphere Interaction in the Accretion-Powered Millisecond Pulsar SAX J1808.4-3658

description: The recent discovery of the first known accretion-powered millisecond pulsar with the Rossi X-Ray Timing Explorer provides the first direct probe of the interaction of an accretion disk with the magnetic field of a weakly magnetic (B<10^10 G) neutron star. We demonstrate that the presence of coherent pulsations from a weakly magnetic neutron star over a wide range of accretion rates places strong constraints on models of the disk-magnetosphere interaction. We argue that the simple Mdot^(3/7) scaling law for the Keplerian frequency at the magnetic interaction radius, widely used to model disk accretion onto magnetic stars, is not consistent with observations of SAX J1808.4-3658 for most proposed equations of state for stable neutron stars. We show that the usually neglected effects of multipole magnetic moments, radiation drag forces, and general relativity must be considered when modeling such weakly magnetic systems. Using only very general assumptions, we obtain a robust estimate of mu~(1-10)x10^26 G cm^3 for the dipole magnetic moment of SAX J1808.4-3658, implying a surface dipole field of ~10^8-10^9 G at the stellar equator. We therefore infer that after the end of its accretion phase, this source will become a normal millisecond radio pulsar. Finally, we compare the physical properties of this pulsar to those of the non-pulsing, weakly magnetic neutron stars in low-mass X-ray binaries and argue that the absence of coherent pulsations from the latter does not necessarily imply that these neutron stars have significantly different magnetic field strengths from SAX J1808.4-3658.

description: Microscopic instability and macroscopic flow pattern resulting from colliding plasmas are studied analytically in support of laboratory experiments. The plasma flows are assumed to stream radially from two separate centers. In a quasi-planar (2D) geometry, they may arise from an Ohmic explosion of two parallel wires, but similar configurations emerge from other outflows, e.g., colliding winds in binary star systems. One objective of this paper is to characterize the flow instabilities developing near the flow stagnation line. An exact solution for the Buneman-type dispersion equation is obtained without conventional simplifications. The unstable wave characteristics are key to anomalous resistivity that determines the reconnection rate of opposite magnetic fields transported with each flow toward the stagnation zone. The second objective of the paper is to calculate the stream function of the plasma shocked upon collision. We addressed this task by mapping the flow region to a hodograph plane and solving a Dirichlet problem for the stream function. By providing the instability growth rate, responsible for anomalous transport coefficients, and the overall flow configuration, these studies lay the ground for the next step. From there, we will examine the field reconnection scenarios and emerging mesoscopic structures, such as radial striata observed in the experiments.

Since the gas mass fraction from the hot ICM is believed to be constant in time, the value of the cosmological deceleration parameter $q_0$ can be determined by comparing the calculated gas mass fraction in nearby and distant clusters (Pen 1997). To test the potential of this method, we compare the gas fractions derived for a sample of luminous ($L_X > 10^{45} $erg s$^{-1}$), nearby clusters with those calculated for eight luminous, distant ($0.3 < z < 0.6$) clusters using ASCA and ROSAT observations. For consistency, we evaluate the gas mass fraction at a fixed physical radius of 1 $h_{50}^{-1}$ Mpc (assuming $q_0=0.0$). We find a best fit value of $q_0 = 0.07$ with -0.47 < q_0 < 0.67 at 95% confidence. We also determine the gas fraction using the method of Evrard, Metzler, & Navarro (1997) to find the total mass within $r_{500}$, the radius where the mean overdensity of matter is 500 times the critical density. In simulations, this method reduces the scatter in the determination of gravitational mass without biasing the mean. We find that it also reduces the scatter in actual observations for nearby clusters, but not as much as simulations suggest. Using this method, the best fit value is $q_0 = 0.04$ with -0.50 < q_0 < 0.64. The excellent agreement between these two methods suggests that this may be a useful technique for determining $q_0$. The constraints on $q_0$ should improve as more distant clusters are studied and precise temperature profiles are measured to large radii.

description: We explore the consequences of a magnetic dynamo origin for the viscosity in accretion discs, for the structure and evolution of discs in dwarf nova systems. We propose that the rapid cooling that sets in at the end of a dwarf nova eruption acts to inhibit the Balbus-Hawley instability, and thereby to quench dynamo action and so reduce disc viscosity. We demonstrate that a modified disc instability model can reproduce the basic properties of dwarf nova eruptions, as well as some properties of quiescent discs. We also discuss some observational consequences of our model.

Experimental and modelling studies of reservoir mineral dissolution following carbon dioxide injection

description: There have been extensive studies of the kinetics of pristine carbonate minerals in acidified media including (CO2 + H2O) systems at elevated temperature and pressure conditions pertinent to carbon storage. However, most of those studies have not considered the several complexities that occur in real reservoirs. The goal of this study was to investigate some of these complexities and their impacts on reaction rates under reservoir conditions. The variables investigated in this study include: aqueous chemistry and ionic strength, saturation state, surface contaminants and chemical heterogeneity in reservoir minerals. The majority of the reaction rates reported in this study are from batch reactor experiments implementing a form of the rotating disk technique, which is chosen to eliminate mass transport effects. Calcite (CaCO3) dissolution kinetics were investigated in (CO2 + H2O + NaCl), (CO2 + H2O + NaHCO3), (CO2 + H2O + Na2SO4) and (CO2 + H2O + Mixed Salts) systems. These studies were carried out at temperatures ranging from (323 to 373) K and pressures ranging from (6 to 10) MPa. A minor increase in the dissolution rates as a function of ionic strength was observed in every system except for (CO2 + H2O + NaHCO3), where a marked reduction in dissolution rates was measured. These observations are consistent with the predicted changes in the pH of the aqueous system. The influence of saturation states in the dissolution kinetics of calcite was investigated in the (CO2 + H2O) system at a temperature T of 373 K and a pressure p of 6 MPa. Consistent with previous studies, the measured dissolution rates deviate from the classical transition state theory (TST) model which was developed for elementary reactions in homogeneous media. A modified TST expression was subsequently proposed. Next, the dissolution kinetics of three chemically heterogeneous carbonate reservoir rocks were investigated in (CO2 + H2O) system at T = 323 K and p = 10 MPa. For a single carbonate mineral in the heterogeneous matrix, the measured dissolution rates were found to be comparable to those of a chemically homogeneous system under similar experimental conditions. Finally, the impact of surface alterations (including adsorbed biofilms and crude-oil films) on calcite dissolution kinetics was investigated in (CO2 + H2O) systems at temperatures ranging from (325 to 333) K and pressures up to 10 MPa. Some of these films made a minor difference in reaction rates and the effects were found to be dependent on temperature, pressure, exposure time and reactor configurations. In this study, extensive characterizations were performed on both fluid and solid phases, and geochemical simulations were implemented in the PHREEQC software. Further, preliminary insights from Lattice Boltzmann modelling and reactive core flooding studies are presented.
A new laser-based technique for simultaneous time-resolved point measurements of flow temperature and velocity using thermographic phosphor tracer particles

description: Turbulent flows involving heat transfer or chemical reactions are important processes in the operation of numerous devices such as engines, and heating and cooling systems. Laser-based measurements of flow temperature and velocity have aided our understanding of the underlying flow physics in such processes. Recently, micron-size thermographic phosphor tracer particles, which are solid materials with temperature-dependent luminescence properties, have been exploited for simultaneous temperature and velocity imaging. However, the measurement strategy, which requires pulsed lasers to illuminate and excite the particles, is typically implemented at low temporal (~10 Hz) and spatial resolutions (>400 µm). Also, it is difficult to implement the technique for near-wall measurements or where limited optical access is required. In this dissertation, an alternative and complementary single-point measurement technique is presented, also based on thermographic phosphor particles. Here, particles seeded in a flow are probed individually when crossing a probe volume formed using continuous wave (CW) lasers. Using photomultiplier tubes to detect the scattering and luminescence signals from the same particle, velocimetry and thermometry are performed simultaneously, at sampling rates up to kHz’s and spatial resolution of 150 µm using a combined laser Doppler velocimetry and phosphor thermometry technique. The development of this measurement technique, based on the two-colour ratio strategy in phosphor thermometry is first described. The technique is demonstrated, using the phosphor BaAl10Mg17:Eu2+, in a heated jet from 293 - 670 K with temperature precision of 4-8%, and accuracy better than 2%. The utility of the technique is further demonstrated for near-wall measurement with accurate measurements performed as close as 200 µm from a heated surface. Another temperature evaluation strategy, which exploits the temperature dependence of the luminescence lifetime, by probing the phase-shifted luminescence from the same phosphor particles when using a modulated excitation source, is also described. The concept is demonstrated in a heated jet above 600 K, with a measurement precision as high as 1% obtained at 840 K. A discussion on applications and future developments of the concept of the ‘thermographic laser Doppler velocimetry’ is also provided.

description: We study axisymmetric accretion of slowly rotating matter onto a gravitation center. The process of the flow restructuring is presented as the angular velocity of accreting gas approaches the Keplerian velocity. For spherically-symmetric accretion we found conditions of existence of steady-state supersonic solutions for various external boundary conditions. These conditions are used for choosing proper initial and boundary conditions for accretion of the rotating matter. The study is performed on the basis of the numerical solution of the Euler gas dynamic equations using the second order extension of the Lax-Friedrichs scheme with the implicit approximation of the source term.

description: Recently two fundamental topological properties of a magnetic vortex at the interface of a superconductor (SC) and a strong topological insulator (TI) have been established: the vortex carries both a Majorana zero-mode relevant for topological quantum computation and, for a time-reversal invariant TI, a charge of $e/4$. This fractional charge is caused by the axion term in the electromagnetic Lagrangian of the TI. Here we determine the angular momentum $J$ of the vortices, which in turn determines their mutual statistics. Solving the axion-London electrodynamic equations including screening in both SC and TI, we find that the elementary quantum of angular momentum of the vortex is $-n^2\hbar/8$, where $n$ is the flux quantum of the vortex line. Exchanging two elementary fluxes thus changes the phase of the wavefunction by $-π/4$.
