Isogeometric finite element methods for liquid metal magnetohydrodynamics
Creators: name: Ahn, Ji Soo
Publisher: name: Imperial College London
Year: 2017

description: A fusion blanket is a key component in a fusion reactor which extracts heat energy, protects the surrounding structure and possibly produces tritium, one of the fuels required for the deuterium-tritium fusion reaction. Interest in magneto-hydrodynamic (MHD) effects in the fusion blanket has been growing due to the promising prospect of a liquid breeder blanket, due to its high power density and the possibility of sustainable production of tritium. However, MHD effects can significantly influence the operating performance of the fusion blanket and an accurate and reliable analysis of the MHD effects are critical in its design. Significant progress in the numerical study of MHD has been made recently, due in large part to the advancement in computing power. However, its maturity has not yet reached a point comparable with standard CFD solvers. In particular, complex domains and complex externally applied magnetic fields present additional challenges for numerical schemes in MHD. For that reason, the application of isogeometric analysis is considered in this thesis. Isogeometric Analysis (IGA) is a new class of numerical method which integrates Computer Aided Design (CAD) into Finite Element Analysis (FEA). In IGA, B-splines and NURBS, which are the building blocks used to construct a geometry in CAD, are also used to build the finite element spaces. This allows to represent geometries more accurately, and in some cases exactly. This may help advance the progress of numerical studies of MHD effects, not only in fusion blanket scenarios, but more widely. In this thesis, we develop and study a number of types of IGA based MHD solver; a fully-developed MHD flow solver, a steady-state MHD solver and a time-dependent MHD solver. These solvers are validated using analytical methods and methods of manufactured solution and are compared with other numerical schemes on a number of benchmark problems.

description: Artificial atoms (AA) offer the possibility to design physical systems implementing new regimes of ultrastrong coupling (USC) between radiation and matter, where previously unexplored non-perturbative physics emerges. While experiments so far provided only spectroscopic evidence of USC, we propose the dynamical detection of virtual photon pairs in the dressed eigenstates, which is a "smoking gun" of the very existence of USC in nature. We show how to coherently amplify this channel to reach 100% efficiency by operating advanced control similar to stimulated Raman adiabatic passage (STIRAP).

description: The Molonglo Observatory Synthesis Telescope, operating at 843 MHz with a 5 square degree field of view, is carrying out a radio imaging survey of the sky south of declination -30 deg. This survey (the Sydney University Molonglo Sky Survey, or SUMSS) produces images with a resolution of 43" x 43" cosec(Dec.) and an rms noise level of about 1 mJy/beam. SUMSS is therefore similar in sensitivity and resolution to the northern NRAO VLA Sky Survey (NVSS; Condon et al. 1998). The survey is progressing at a rate of about 1000 square degrees per year, yielding individual and statistical data for many thousands of weak radio sources. This paper describes the main characteristics of the survey, and presents sample images from the first year of observation.

Selection Effects, Biases, and Constraints in the Calan/Tololo Supernova Survey

Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: We use Monte Carlo simulations of the Calan/Tololo photographic supernova survey to show that a simple model of the survey's selection effects accounts for the observed distributions of recession velocity, apparent magnitude, angular offset, and projected radial distance between the supernova and the host galaxy nucleus for this sample of Type Ia supernovae (SNe Ia). The model includes biases due to the flux-limited nature of the survey, the different light curve morphologies displayed by different SNe Ia, and the difficulty of finding events projected near the central regions of the host galaxies. From these simulations we estimate the bias in the zero-point and slope of the absolute magnitude-decline rate relation used in SNe Ia distance measurements. For an assumed intrinsic scatter of 0.15 mag about this relation, these selection effects decrease the zero-point by 0.04 mag. The slope of the relation is not significantly biased. We conclude that despite selection effects in the survey, the shape and zero-point of the relation determined from the Calan/Tololo sample are quite reliable. We estimate the degree of incompleteness of the survey as a function of decline rate and estimate a corrected luminosity function for SNe Ia in which the frequency of SNe appears to increase with decline rate (the fainter SNe are more common). Finally, we compute the integrated detection efficiency of the survey in order to infer the rate of SNe Ia from the 31 events found. For a value of Ho=65 km/sec/Mpc we obtain a SN Ia rate of 0.21(+0.30)(-0.13) SNu. This is in good agreement with the value 0.16+/-0.05 SNu recently determined by Capellaro et al. (1997).

description: With increasing availability of spectrum in the market due to new spectrum allocation and re-farming bands from previous cellular generation networks, a more flexible, efficient and green usage of the spectrum becomes an important topic in 5G-Advanced. In this article, we provide an overview on the 3rd Generation Partnership Project (3GPP) work on flexible spectrum orchestration for carrier aggregation (CA). The configuration settings, requirements and potential specification impacts are analyzed. Some involved Release 18 techniques, such as multi-cell scheduling, transmitter switching and network energy saving, are also presented. Evaluation results show that clear performance gain can be achieved by these techniques.

description: The question of the relative importance of coherent structures and waves has for a long time attracted a great deal of interest in astrophysical plasma turbulence research, with a more recent focus on kinetic scale dynamics. Here we utilize high-resolution observational and simulation data to investigate the nature of waves and structures emerging in a weakly collisional, turbulent kinetic plasma. Observational results are based on in situ solar wind measurements from the Cluster and MMS spacecraft, and the simulation results are obtained from an externally driven, three-dimensional fully kinetic simulation. Using a set of novel diagnostic measures we show that both the large-amplitude structures and the lower-amplitude background fluctuations preserve linear features of kinetic Alfven waves to order unity. This quantitative evidence suggests that the kinetic turbulence cannot be described as a mixture of mutually exclusive waves and structures but may instead be pictured as an ensemble of localized, anisotropic wave packets or "eddies" of varying amplitudes, which preserve certain linear wave properties during their nonlinear evolution.

Thermo-hydro-mechanical coupling within a geomechanical multiphase model framework with special reference to fractured rock masses in the vicinity of a geological disposal facility for radioactive waste
Creators: name: Joulin, Clément
Publisher: name: Imperial College London
Year: 2019

description: A novel numerical approach for the modelling of Thermo-Hydro-Mechanical (THM) processes in the vicinity of a Geological Disposal Facility (GDF) for the long-term storage of radioactive waste is presented. This work is based on a dual numerical code framework with a multiphase flow solver for thermo-hydraulic processes and a geo-mechanical solver for mechanical processes in fractured and fracturing rock masses. The method has a unique continuum-discontinuum configuration that allows each of the THM processes to be represented with the most suited formulation, thus improving the accuracy and complexity of the simulations. Thermal processes are implemented within the geo-mechanical solver using both an explicit and an implicit approach, the latter allowing the modelling of temperature over large time scales, an important feature in the context of geological disposal. Moreover, a novel thermal contact approach is presented to investigate the heat transfer between contacting solids and its application to heat transfer across fractures is discussed. Furthermore, a thermo-mechanical coupling formulation is derived in the geo-mechanical solver, enabling thermal expansion and thermally induced fracturing. Then, the THM coupling is finalised using a conservative projection method that enables information exchange between superimposed numerical meshes e.g. heat transfer between the thermo-hydraulic and the thermo-mechanical solvers. Both applications in porous media and with laminar flow are explored. Finally, the THM dual framework is applied to the modelling of thermal spalling occurring in the excavation walls of a deposition hole in a GDF. The potential of the method to offer new predictive capabilities and insights on unexplained experimental observations is demonstrated by considering the concurrence over time of THM factors influencing spalling, especially multi-phase flow in the continuum and explicitly represented fractures in the discontinuum.

Quantifying the Intrinsic Usefulness of Attributional Explanations for Graph Neural Networks with Artificial Simulatability Studies

description: Despite the increasing relevance of explainable AI, assessing the quality of explanations remains a challenging issue. Due to the high costs associated with human-subject experiments, various proxy metrics are often used to approximately quantify explanation quality. Generally, one possible interpretation of the quality of an explanation is its inherent value for teaching a related concept to a student. In this work, we extend artificial simulatability studies to the domain of graph neural networks. Instead of costly human trials, we use explanation-supervisable graph neural networks to perform simulatability studies to quantify the inherent usefulness of attributional graph explanations. We perform an extensive ablation study to investigate the conditions under which the proposed analyses are most meaningful. We additionally validate our methods applicability on real-world graph classification and regression datasets. We find that relevant explanations can significantly boost the sample efficiency of graph neural networks and analyze the robustness towards noise and bias in the explanations. We believe that the notion of usefulness obtained from our proposed simulatability analysis provides a dimension of explanation quality that is largely orthogonal to the common practice of faithfulness and has great potential to expand the toolbox of explanation quality assessments, specifically for graph explanations.

description: The Large Hadron Collider (LHC) has confirmed the Higgs mechanism to be responsible for generating mass in the Standard Model (SM), making it attractive to also consider spontaneous symmetry breaking as the origin of mass for new particles in a dark sector extension of the SM. Such a dark Higgs mechanism may in particular give mass to a dark matter candidate and to the gauge boson mediating its interactions (called dark photon). In this review we summarise the phenomenology of the resulting dark Higgs boson and discuss the corresponding search strategies with a focus on collider experiments. We consider both the case that the dark Higgs boson is heavier than the SM Higgs boson, in which case leading constraints come from direct searches for new Higgs bosons as well missing-energy searches at the LHC, and the case that the dark Higgs boson is (potentially much) lighter than the SM Higgs boson, such that the leading sensitivity comes from electron-positron colliders and fixed-target experiments. Of particular experimental interest for both cases is the associated production of a dark Higgs boson with a dark photon, which subsequently decays into SM fermions, dark matter particles or long-lived dark sector states. We also discuss the important role of exotic decays of the SM-like Higgs boson and complementary constraints arising from early-universe cosmology, astrophysics and direct searches for dark matter in laboratory experiments.

description: A three dimensional Molecular Dynamics (MD) simulation is carried out to explore the equilibrium configurations of charged dust particles. These equilibrium configuration are of astrophysical significance for the conditions of molecular clouds and the interstellar medium. The interaction among the dust grains is modeled by Yukawa repulsion and gravitational attraction. The spherically symmetric equilibria are constructed which are characterized characterized by three parameters: (i) the number of particles in the cloud, (ii) $Γ_g$ (defined in the text) where $Γ_g^{-1}$ is the short range cutoff of the interparticle potential, and (iii) the temperature of the grains. The effects of these parameters on dust cloud are investigated using radial density profile. The problem of equilibrium is also formulated in the mean field limit where total dust pressure which is the sum of kinetic pressure and electrostatic pressure, balances the self-gravity. The mean field solutions agree well with the results of MD simulations. Astrophysical significance of the results is briefly discussed.

The observations include multifrequency VLBI measurements, X-ray observations with ROSAT and submillimeter observations with the JCMT. Particularly interesting among many findings is a correlation between the X-ray to millimeter spectral index and fraction of flux density contained in the VLBI core. This tendency toward higher X-ray fluxes from sources with stronger jet emission implies that the knots in the jet are the prominent source of X-rays.

Applications of modal decomposition algorithms to dynamic estimation and reconstruction of fluid flows
Creators: name: Krol, Jakub
Publisher: name: Imperial College London
Year: 2017

description: In this thesis, modal decomposition algorithms are utilised to construct reduced-order models of the fluid flows with applications to estimator design and extraction of the dynamical information from the irregularly sampled data. A particular implementation of such algorithms, the Optimal Mode Decomposition (OMD), is used to construct the estimator frameworks for bluff body flows, more specifically past a circular cylinder and bullet-shaped object. Estimator design is motivated by feedback flow control applications in which online knowledge of the system is paramount. Reduced order models are constructed and combined with stochastic estimation techniques using Moving Horizon Estimation (MHE) algorithm to achieve accurate representations of primary oscillatory and transient features of the cylinder flow across all of its dynamically distinct regimes. The designed estimator is subsequently extended to turbulent flow past a three-dimensional axisymmetric bluff body by introducing rotation-dependent framework. This is able to approximate the main oscillatory features of the flow despite the dynamical complexity of the system. Furthermore, an extension to the OMD algorithm is introduced, referred to as the is-OMD algorithm, which allows modal decomposition techniques to be applied to vector-valued signal, such as an ensemble of PIV snapshots, sampled at random time instances. A mapping between underlying time-resolved snapshots and known measurements is defined and data is projected onto a low-order subspace. Subsequently, dynamical characteristics, such as frequencies and growth rates, are approximated by iteratively solving two optimisation sub-problems: consecutively updating a reduced-order dynamical model, then subsequently approximating the `missing' data at intermediate snapshots between the known values. The methodology is demonstrated on three dynamical systems: a synthetic sinusoid, the cylinder wake at Re = 60 and turbulent flow past an axisymmetric bullet-shaped body. In all cases the algorithm is shown to correctly identify the characteristic frequencies and oscillatory structures present in the flow from downsampled data ensemble.

description: Underwater acoustic target recognition is an intractable task due to the complex acoustic source characteristics and sound propagation patterns. Limited by insufficient data and narrow information perspective, recognition models based on deep learning seem far from satisfactory in practical underwater scenarios. Although underwater acoustic signals are severely influenced by distance, channel depth, or other factors, annotations of relevant information are often non-uniform, incomplete, and hard to use. In our work, we propose to implement Underwater Acoustic Recognition based on Templates made up of rich relevant information (hereinafter called "UART"). We design templates to integrate relevant information from different perspectives into descriptive natural language. UART adopts an audio-spectrogram-text tri-modal contrastive learning framework, which endows UART with the ability to guide the learning of acoustic representations by descriptive natural language. Our experiments reveal that UART has better recognition capability and generalization performance than traditional paradigms. Furthermore, the pre-trained UART model could provide superior prior knowledge for the recognition model in the scenario without any auxiliary annotation.

Shear flow instabilities in pipes and channels
Creators: name: Gipon, Matthew
Publisher: name: Imperial College London
Year: 2018

description: Two broad problems are considered in this thesis. The first investigation focuses on the spatial stability of pressure driven flow in a pipe, while the second problem is concerned with temporal stability of Couette flow in a parallel wall channel. A similar approach is taken with both halves of this thesis: an asymptotic analytical model is developed and this is then solved with numerical methods. The prominent problem in the first chapter is Hagen-Poiseuille flow with suction and injection on the pipe wall boundary. The flow is fully developed in the axial direction and the suction acts radially at the wall while the other boundary conditions are no-slip. The flow is perturbed by a small non-axisymmetric disturbance and this configuration is solved in the radial-azimuthal plane. The results are provided for 2pi-periodic suction and it is found that the non-parallel base flow is unstable in certain conditions. The suction coefficient is varied but the critical Reynolds number is found to be the same. A weakly nonlinear stability analysis reveals that there is a finite amplitude solution in the supercritical region. The second chapter presents the vortex-wave interaction equations and a special case of the model is created to seek stationary, equilibrium solutions of the sinuous wave disturbance in Couette flow. The flow is initiated with an artificial forcing which has the sinusoidal symmetries embedded. From this initial condition the `roll' problem is solved and the `streak' can be found from this solution. The wave on this streak has Reynolds stresses which now force the `roll'. The amplitude of the wave is varied and the system is iterated until the wave is neutral. This equilibrium configuration is then marched forward in time and studied. The solutions agree with numerical calculations and experiments.

description: Employing a procedure called monitoring---via a completely positive trace-preserving map that is able to interpolate between weak and projective measurements---we investigate the resilience of the recently proposed realism-based nonlocality to local and bilocal weak measurements. This analysis indicates realism-based nonlocality as the most ubiquitous and persistent form of quantumness within a wide class of quantum-correlation quantifiers. In particular, we show that the set of states possessing this type of quantumness forms a strict superset of symmetrically discordant states and, therefore, of discordant, entangled, steerable, and Bell-nonlocal states. Moreover, we find that, under monitoring, realism-based nonlocality is not susceptible to sudden death.

Through every point in such a metric there is a geodesic that saturates the length condition, and saturating geodesics in a given homotopy class form a band. The extremal metric is unknown when bands of geodesics cross, as it happens for surfaces of non-zero genus. We use recently proposed convex programs to numerically find the minimal-area metric on the square torus with a square boundary, for various sizes of the boundary. For large enough boundary the problem is equivalent to the "Swiss cross" challenge posed by Strebel. We find that the metric is positively curved in the two-band region and flat in the single-band regions. For small boundary the metric develops a third band of geodesics wrapping around it, and has both regions of positive and negative curvature. This surface can be completed to provide the minimal-area metric on a once-punctured torus, representing a closed-string tadpole diagram.

description: This paper introduces for the first time the design, modelling, and control of a novel morphing multi-rotor Unmanned Aerial Vehicle (UAV) that we call the OmniMorph. The morphing ability allows the selection of the configuration that optimizes energy consumption while ensuring the needed maneuverability for the required task. The most energy-efficient uni-directional thrust (UDT) configuration can be used, e.g., during standard point-to-point displacements. Fully-actuated (FA) and omnidirectional (OD) configurations can be instead used for full pose tracking, such as, e.g., constant attitude horizontal motions and full rotations on the spot, and for full wrench 6D interaction control and 6D disturbance rejection. Morphing is obtained using a single servomotor, allowing possible minimization of weight, costs, and maintenance complexity. The actuation properties are studied, and an optimal controller that compromises between performance and control effort is proposed and validated in realistic simulations. Preliminary tests on the prototype are presented to assess the propellers' mutual aerodynamic interference.

Testing a Quantum Inequality with a Meta-analysis of Data from Squeezed Light

description: In quantum field theory, coherent states can be created that have negative energy density, meaning it is below that of empty space, the free quantum vacuum. If no restrictions existed regarding the concentration and permanence of negative energy regions, it might, for example, be possible to produce exotic phenomena such as Lorentzian transversable wormholes, warp drives, time machines, violations of the second law of thermodynamics, and naked singularities. Quantum Inequalities (QIs) have been proposed that restrict the size and duration of the regions of negative quantum vacuum energy that can be accessed by observers. However, QIs generally are derived for situations in cosmology and are very difficult to test. Direct measurement of vacuum energy is difficult and to date no QI has been tested experimentally. We test a proposed QI for squeezed light by a meta-analysis of published data obtained from experiments with optical parametric amplifiers (OPA) and balanced homodyne detection. Over that last three decades, researchers in quantum optics have been trying to maximize the squeezing of light and the quantum vacuum and have succeeded in reducing the variance in the quantum vacuum fluctuations to -15 dB. To apply the QI, a time sampling function is required. In our meta-analysis different time sampling functions for the QI were examined, but in all physically reasonable cases the QI is violated by much or all of the measured data. This brings into question the basis for QI. Possible explanations are given for this surprising result.

Nonlinear optimal control of bypass transition in a flat plate boundary layer
Creators: name: Xiao, Dandan
Publisher: name: Imperial College London
Year: 2017

description: In this thesis a nonlinear optimal control algorithm is designed to suppress bypass transition in a zero pressure gradient boundary layer subjected to free stream vortical disturbances using direct numerical simulation (DNS). The inflow condition is a superposition of the Blasius velocity profile and two modes of the continuous spectrum of the Orr- Sommerfeld and Squire equations. Transition is realised through the outer secondary instability mode, which results from the interaction between the elevated low speed streaks and the high frequency mode in the free stream. The optimal control problem is solved using a Lagrange variational technique that results in a set of linearised adjoint equations. The optimal wall actuation (blowing and suction from a control slot located in the transition region) is found by solving iteratively the nonlinear Navier-Stokes and the adjoint equations in a forward/backward loop over a finite time horizon. The optimal controller is effective in reducing the flow energy in a single optimisation horizon. It is found that the optimal control velocity has mean positive value (indicating net blowing) when there is no constraint on mass flow rate and its distribution reflects the flow above the control slot during the short optimisation time. Optimisation over longer time is limited by adjoint instability due to the chaotic nature of the uncontrolled flow. A receding horizon approach is used in order to compute the control velocity for longer time. A different control mechanism is observed as the optimisation time covers the full transition process and the optimal control reacts to it. Zero mass flow rate constraint enforces negative control velocity in the upstream side of the slot. The results show that the resulting adverse pressure gradient (due to suction) leads to abrupt transition in the upstream side of the slot, and control with this constraint is less efficient.

description: Analyzing the ocean acoustic environment is a tricky task. Background noise and variable channel transmission environment make it complicated to implement accurate ship-radiated noise recognition. Existing recognition systems are weak in addressing the variable underwater environment, thus leading to disappointing performance in practical application. In order to keep the recognition system robust in various underwater environments, this work proposes an adaptive generalized recognition system - AGNet (Adaptive Generalized Network). By converting fixed wavelet parameters into fine-grained learnable parameters, AGNet learns the characteristics of underwater sound at different frequencies. Its flexible and fine-grained design is conducive to capturing more background acoustic information (e.g., background noise, underwater transmission channel). To utilize the implicit information in wavelet spectrograms, AGNet adopts the convolutional neural network with parallel convolution attention modules as the classifier. Experiments reveal that our AGNet outperforms all baseline methods on several underwater acoustic datasets, and AGNet could benefit more from transfer learning. Moreover, AGNet shows robust performance against various interference factors.
The Age, Extinction and Distance of the Old, Metal-Rich Open Cluster NGC 6791

description: An extensive grid of metal-rich isochrones utilizing the latest available input physics has been calculated for comparison with the old, metal-rich open cluster NGC 6791. The isochrones have been simultaneously fit to BV and VI color magnitude diagrams, with the same composition, reddening and distance modulus required for both colors. Our best fitting isochrone assumes [Fe/H] = +0.4, scaled solar abundance ratios, and dY/dZ = 2 (Y = 0.31), yielding an excellent fit to the data at all points along the major sequences. The resulting age is 8 Gyr, with E(B-V) = 0.10 and (m-M)_v = 13.42. The derived cluster parameters are fairly robust to variations in the isochrone [Fe/H] and helium abundances. All of the acceptable fits indicate that 0.07 < E(B-V) < 0.14$, 13.29 < (m-M)_v < 13.46, and that NGC 6791 has an age of 8.0+/- 0.5 Gyr. The fits also suggest that dY/dZ lies between 1 and 3. A metallicity as low as solar is clearly ruled out, as is dY/dZ = 0. Comparison with previous isochrone studies indicates that the derived reddening is primarily due to our use of the most recent color transformations, whereas the age depends upon both the colors and the input physics. Our isochrones provide an excellent fit to the Hyades zero-age main sequence as determined by Hipparcos, providing evidence that our derived reddening and distance modulus are reliable.

description: Persistence diagrams are important descriptors in Topological Data Analysis. Due to the nonlinearity of the space of persistence diagrams equipped with their {\em diagram distances}, most of the recent attempts at using persistence diagrams in machine learning have been done through kernel methods, i.e., embeddings of persistence diagrams into Reproducing Kernel Hilbert Spaces, in which all computations can be performed easily. Since persistence diagrams enjoy theoretical stability guarantees for the diagram distances, the {\em metric properties} of the feature map, i.e., the relationship between the Hilbert distance and the diagram distances, are of central interest for understanding if the persistence diagram guarantees carry over to the embedding. In this article, we study the possibility of embedding persistence diagrams into separable Hilbert spaces, with bi-Lipschitz maps. In particular, we show that for several stable embeddings into infinite-dimensional Hilbert spaces defined in the literature, any lower bound must depend on the cardinalities of the persistence diagrams, and that when the Hilbert space is finite dimensional, finding a bi-Lipschitz embedding is impossible, even when restricting the persistence diagrams to have bounded cardinalities.
