Automated optimization of reconfigurable designs
Creators: name: Kurek, Maciej
Publisher: name: Imperial College London
Year: 2015

description: Currently, the optimization of reconfigurable design parameters is typically done manually and often involves substantial amount effort. The main focus of this thesis is to reduce this effort. The designer can focus on the implementation and design correctness, leaving the tools to carry out optimization. To address this, this thesis makes three main contributions. First, we present initial investigation of reconfigurable design optimization with the Machine Learning Optimizer (MLO) algorithm. The algorithm is based on surrogate model technology and particle swarm optimization. By using surrogate models the long hardware generation time is mitigated and automatic optimization is possible. For the first time, to the best of our knowledge, we show how those models can both predict when hardware generation will fail and how well will the design perform. Second, we introduce a new algorithm called Automatic Reconfigurable Design Efficient Global Optimization (ARDEGO), which is based on the Efficient Global Optimization (EGO) algorithm. Compared to MLO, it supports parallelism and uses a simpler optimization loop. As the ARDEGO algorithm uses multiple optimization compute nodes, its optimization speed is greatly improved relative to MLO. Hardware generation time is random in nature, two similar configurations can take vastly different amount of time to generate making parallelization complicated. The novelty is efficient use of the optimization compute nodes achieved through extension of the asynchronous parallel EGO algorithm to constrained problems. Third, we show how results of design synthesis and benchmarking can be reused when a design is ported to a different platform or when its code is revised. This is achieved through the new Auto-Transfer algorithm. A methodology to make the best use of available synthesis and benchmarking results is a novel contribution to design automation of reconfigurable systems.

description: The roles of different nodes within a network are often understood through centrality analysis, which aims to quantify the capacity of a node to influence, or be influenced by, other nodes via its connection topology. Many different centrality measures have been proposed, but the degree to which they offer unique information, and such whether it is advantageous to use multiple centrality measures to define node roles, is unclear. Here we calculate correlations between 17 different centrality measures across 212 diverse real-world networks, examine how these correlations relate to variations in network density and global topology, and investigate whether nodes can be clustered into distinct classes according to their centrality profiles. We find that centrality measures are generally positively correlated to each other, the strength of these correlations varies across networks, and network modularity plays a key role in driving these cross-network variations. Data-driven clustering of nodes based on centrality profiles can distinguish different roles, including topological cores of highly central nodes and peripheries of less central nodes. Our findings illustrate how network topology shapes the pattern of correlations between centrality measures and demonstrate how a comparative approach to network centrality can inform the interpretation of nodal roles in complex networks.

The Jurassic/Cretaceous boundary: a hidden mass extinction in tetrapods?
Creators: name: Tennant, Jonathan
Publisher: name: Imperial College London
Year: 2016

description: Reconstructing deep time trends in biodiversity remains a central goal for palaeobiologists, but our understanding of the magnitude and tempo of extinctions and radiations is confounded by uneven sampling of the fossil record. In particular, the Jurassic/Cretaceous (J/K) boundary, 145 million years ago, remains poorly understood. By applying a range of techniques for assessing changes in diversity, I demonstrate that both marine and non-marine tetrapod faunas show evidence for a protracted period of regional and global ecological and taxonomic reorganisation across the J/K boundary. Although much of the signal is exclusively European, almost every higher tetrapod group was affected by a substantial decline across the boundary, culminating in the extinction of several important clades and the ecological release and radiation of numerous modern tetrapod groups, including amphibians, birds and sharks. Groups such as pterosaurs and sauropods began their decline before the J/K boundary, whereas others (including mammaliaforms and ornithischians) did not appear to be affected at the J/K boundary, but declined subsequently in the earliest Cretaceous. However, the majority of clades document their greatest magnitude of decline through the Jurassic–Cretaceous boundary, indicating that the overall extinction tempo was staggered and occurred in a ‘wave’ through the J/K transition. These major shifts in tetrapod diversity are shown to be independent of both global and regional sampling proxies, except for the North American record for which evidence of the common cause hypothesis is strong. Variation in eustatic sea level was the primary driver of these patterns, controlling biodiversity through availability of shallow marine environments and via allopatric speciation on land. I further investigated the systematics of Atoposauridae, poorly known group of highly-specialised crocodyliforms that appear to have crossed through the J/K boundary. A detailed revision of their taxonomy and systematics indicates that they went extinct at the J/K boundary.

description: Hubble Space Telescope ultraviolet (UV) images of nine starburst galaxies reveal them to be highly irregular, even after excluding compact sources (clusters and resolved stars). Most (7/9) are found to have a similar intrinsic effective surface brightnesses, suggesting that a negative feedback mechanism is setting an upper limit to the star formation rate per unit area. All starbursts in our sample contain UV bright star clusters indicating that cluster formation is an important mode of star formation in starbursts. On average about 20% of the UV luminosity comes from these clusters. The brightest clusters, or super star clusters (SSC), are preferentially found at the very heart of starbursts. The size of the nearest SSCs are consistent with those of Galactic globular clusters. The luminosity function of SSCs is well represented by a power law with a slope alpha ~ -2. There is a strong correlation between the far infrared excess and the UV spectral slope. The correlation is well modeled by a geometry where much of their dust is in a foreground screen near to the starburst, but not by a geometry of well mixed stars and dust.

Multidirectional near-wall flow in arteries and its spatial correlation with atherosclerosis
Creators: name: Mohamied, Yumnah
Publisher: name: Imperial College London
Year: 2016

description: Atherosclerotic lesions develop non-uniformly throughout the arterial system and their distribution around branches changes with age. This thesis investigates whether multidirectional blood flow, characterised by the transverse wall shear stress metric (transWSS), is related to the initiation of atherosclerosis. The spectral/hp element method was used to simulate pulsatile blood flow in immature and mature rabbit aortic geometries obtained by microCT of vascular corrosion casts. Bootstrapping was used to quantitatively correlate spatial maps around intercostal branch ostia, and found that the low/oscillatory shear theory did not correlate with disease, and could not account for age-related changes in macromolecule uptake. However, evidence for the multidirectional theory was found: transWSS related strongly and positively with disease at both ages and with wall permeability in young rabbits. The pulsatility of the blood is necessary for the existence of multidirectionality, yet the precise nature of the cardiac waveform did not dominantly influence both the large- and small-scale pattern of transWSS. Simulations in partially-idealised vessels revealed that geometry instead was crucial. Vessel curvature was responsible for a Dean vortex pair, whose changing strength over the cardiac cycle created changes in the shear direction at the wall, resulting in two large-scale axial streaks of high transWSS. Vessel torsion determined the asymmetry in their strengths and spatial locations over the descending aorta. Two distributions of transWSS resembling the age-dependent lesion patterns were identified at the individual-branch level, but which arose equally in both age groups. The small-scale patterns were found to depend on the branch's location with respect to the large-scale streaks, and therefore primarily on torsion, for which no statistically significant difference between age groups was found. Multidirectional flow relates well to disease at the aggregate-level and may explain age-dependent lesion patterns. The importance of geometry was highlighted, and calls into question how accurately it is captured.

Asymptotic analysis of array-guided waves
Creators: name: Maling, Ben
Publisher: name: Imperial College London
Year: 2016

description: We develop and apply computational and analytical techniques to study wave-like propagation and resonant effects in periodic and quasi-periodic systems. Two themes that unify the content herein are the guidance and confinement of energy using periodic structures, and the utility of asymptotic analysis to aid computation and produce results that lend physical insight to the problems in question. In the first research chapter, we develop the method of high-frequency homogenisation (HFH) for electromagnetic waves in dielectric media, and apply this to the example of a planar array of dielectric spheres. The theory conveniently describes a range of dynamic effects, including effectively anisotropic behaviour in certain frequency regimes. In the second research chapter, we apply the HFH method to a cylindrical Bragg fibre, and use this to set up an effective eigenvalue problem in which the quasi-periodic system representing the fibre cladding is represented by a single continuous Bessel-like equation. We compare the results with those of direct numerical simulations and discuss how the theory could be developed to aid the study of photonic crystal cavities or fibres. In the remaining chapters, we consider the complex resonances of structures with angular periodicity. We demonstrate the emergence of quasi-normal modes with high Q-factors for the Helmholtz equation in such domains, and explore some of their properties using multiple scale analysis. In the final two chapters, we focus on a particular subset of these domains, and using matched asymptotic expansions show that the Q-factors for certain solutions depend exponentially on the number of inclusions arranged in a circular ring. Finally, we extend this analysis to flexural waves in thin elastic plates, and discuss the possibility of structured-ring resonators based on these solutions.

description: The singly-ionized lutetium has a number of fortuitous properties well suited for a design of an optical clock and corresponding applications. In this work, we study Lu+ properties relevant to a development of the clock using the relativistic high-precision method combining configuration interaction and the linearized coupled-cluster approaches. The systematic effects due to interaction of an external electric-field gradient with the quadrupole moment and the dynamic correction to the blackbody radiation shift are studied and uncertainties are estimated. The value of the 5d6s 1D_2 polarizability is predicted. We also demonstrate that Lu+ is a good candidate to search for variation of the fine-structure constant.

A stability framework for variable selection, graphical modelling and clustering: applications in lung cancer research
Creators: name: Bodinier, Barbara
Publisher: name: Imperial College London
Year: 2022

description: Decades of research have shown that various biological mechanisms are deregulated during carcinogenesis. By offering an agnostic view of individual molecular profiles, high-throughput technologies have enabled new avenues to investigate these molecular changes. These technological developments have also raised novel statistical challenges for the generation of interpretable and robust findings from high dimensional and heterogenous datasets. Regularisation has been instrumental in the analysis of such data by enabling estimations in high dimension and inducing sparsity in the results. Reproducibility issues can be circumvented by combining regularised models with resampling techniques in stability selection or consensus clustering. However, these stability approaches are still under-used, possibly due to the sensitivity of the results to the choice of hyper-parameters and the complexity of their calibration. In the present thesis, I propose to calibrate hyper-parameters of stability selection (for regression or graphical modelling) or consensus clustering by maximising novel scores measuring results stability. To evaluate the performance of this procedure, and compare it with state-of-the-art calibration techniques, I develop flexible simulation models based on the multivariate Normal distribution. Extensive simulation studies suggest that calibration using the novel scores outperforms existing approaches for no increase in computational cost. The proposed models are then used on real omics datasets in a lung cancer case-control study to identify molecular markers of lung carcinogenesis. The use of stability selection in a structural causal modelling framework enables the identification of both (i) potential biological mediators of the effect of tobacco smoking on lung carcinogenesis, and (ii) smoking-independent markers of lung cancer. To facilitate the use of these novel techniques, I have created two R packages, freely available on CRAN. Stability selection and consensus clustering, along with the novel calibration procedures, have been implemented in the R package sharp. Simulation functions are available in the R package fake.

description: The World Wide Web and the Semantic Web are designed as a network of distributed services and datasets. The distributed character of the Web brings manifold collaborative possibilities to interchange data. The commonly adopted collaborative solutions for RDF data are centralized (e.g. SPARQL endpoints and wiki systems). But to support distributed collaboration, a system is needed, that supports divergence of datasets, brings the possibility to conflate diverged states, and allows distributed datasets to be synchronized. In this paper, we present Quit Store, it was inspired by and it builds upon the successful Git system. The approach is based on a formal expression of evolution and consolidation of distributed datasets. During the collaborative curation process, the system automatically versions the RDF dataset and tracks provenance information. It also provides support to branch, merge, and synchronize distributed RDF datasets. The merging process is guarded by specific merge strategies for RDF data. Finally, we use our reference implementation to show overall good performance and demonstrate the practical usability of the system.

Limit theorems and stochastic models for dependence and contagion in financial markets
Creators: name: Granelli, Andrea
Publisher: name: Imperial College London
Year: 2016

description: We analyse the effect of dependence between financial assets in the setting of the variance risk premium and the Brownian semistationary process. The variance risk premium (VRP) refers to the premium demanded for holding assets whose variance is exposed to stochastic shocks. This thesis identifies a new modelling framework for equity indices and presents for the first time explicit analytical formulas for their VRP in a multivariate stochastic volatility setting, which includes multivariate non-Gaussian Ornstein Uhlenbeck processes and Wishart processes. Moreover, we propose to incorporate contagion within the equity index via a multivariate Hawkes process and find that the resulting dynamics of the VRP represent a convincing alternative to the models studied in the literature up to date. The Brownian semistationary process (BSS) is in general not a semimartingale and its univariate asymptotic limit theory outside the semimartingale framework has been developed over recent years, due to the increasing number of its applications in finance and also in the modelling of turbulence. We expand the reach of the theory by proving new probabilistic limit theorems for the 2-dimensional version of the process, using techniques from Malliavin calculus.

A Sub-Relativistic Shock Model for the Radio Emission of SN1998bw

Publisher: name: arXiv
Year: 1998

description: SN1998bw is the most luminous radio supernova ever observed. Previous discussions argued that its exceptional radio luminosity, 4e38 erg/s, must originate from a highly relativistic shock which is fully decoupled from the supernova ejecta. Here we present an alternative model in which the radio emission originates from a sub-relativistic shock with a velocity of 0.3c, generated in the surrounding gas by the expanding ejecta. In this model, thermal electrons heated by the shock to a relativistic temperature of 60 MeV emit synchrotron self-absorbed radiation in the post-shock magnetic field. This model provides an excellent fit to the observed spectra provided that the thermal electrons are in equipartition with the ions behind the shock. The required magnetic field is much weaker than its equipartition value and could have been carried out by the progenitor's wind prior to the supernova explosion. According to this model, the radio emission from SN1998bw is unrelated to the highly relativistic blast wave that produced the gamma-ray burst GRB980425.

Variations of the Selective Extinction Across the Galactic Bulge - Implications for the Galactic Bar

Publisher: name: arXiv

description: We propose a new method to investigate the coefficient of the selective extinction, based on two band photometry. This method uses red clump stars as a means to construct the reddening curve. We apply this method to the OGLE color-magnitude diagrams to investigate the variations of the selective extinction towards various parts of the Galactic bulge. We find that $A_{_V}/E_{_{V-I}}$ coefficient is within the errors the same for $l=\pm 5°$ OGLE fields. Therefore, the difference of $\sim 0.37\;mag$ in the extinction adjusted apparent magnitude of the red clump stars in these fields (Stanek et al.~1994, 1995) cannot be assigned to a large-scale gradient of the selective extinction coefficient. This strengthens the implication of this difference as indicator of the presence of the bar in our Galaxy. However using present data we cannot entirely exclude the possibility of $\sim 0.2\;mag/mag$ variations of the selective extinction coefficient on the large scales across the bulge.

description: We investigate anisotropic compact stars in the non-minimal $Y(R)F^2$ model of gravity which couples an arbitrary function of curvature scalar $Y(R)$ to the electromagnetic field invariant $F^2$. After we obtain exact anisotropic solutions to the field equations of the model, we apply the continuity conditions to the solutions at the boundary of the star. Then we find the mass, electric charge, and surface gravitational redshift by the parameters of the model and radius of the star.

The impact of prime-boost interval on antibody responses in HIV vaccination
Creators: name: Kratochvil, Sven
Publisher: name: Imperial College London
Year: 2017

description: The HIV pandemic has been a global health emergency for more than 30 years with an annual reoccurrence of 2 million new HIV-infections. Implementation of existing prevention measures has proven challenging, highlighting the need for an efficacious HIV vaccine. However, to date the only HIV vaccine trial to demonstrate even modest efficacy was the RV144 study. The results of this trial identified several key features, such as suggesting correlates of protection, selection of the vaccine-delivery mode, design of the immunogens and optimisation of the immunisation regimen, all are potentially imperative for effective vaccine development. Optimisation of immunisation schedules is critical for shaping the profile of vaccine- induced immune responses, the primary focus of research in this thesis. The overall aim of the thesis was to evaluate the effect of alternately timed booster regimens on both humoral and cellular immune responses to the candidate HIV-1 Env protein CN54gp140, adjuvanted with GLA-AF. For this purpose, study participants received a common 3-dose intramuscular priming series followed by a final booster at either 6 or 12 months. The longitudinal tracking of immune responses revealed that the two homologous prime- boost regimens safely and effectively induced CN54gp140-specific responses in systemic and mucosal compartments. Levels of vaccine-induced IgG-subclass antibodies correlated significantly with the engagement of Fc-receptors and both vaccine-regimens were associated with identical patterns in titre and functional antibody response profiles. Additional depth was added to the characterisation of CN54gp140 vaccine regimens through the evaluation of Env- specific monoclonal antibody responses. In summary, the combined data revealed significant similarities in response magnitude and antibody profiles associated with both immunisation schedules. The findings strongly suggest that the 6-month regimen can be adopted for the rapid induction of immune responses against CN54gp140 without affecting response magnitude, antibody diversity or functionality adversely.
Multiscale predictive modelling of ultra-high temperature structural ceramics
Creators: name: Pettina', Michele
Publisher: name: Imperial College London
Year: 2016

description: Components in high-flow environments such as hypersonic vehicle nose cap and leading edges are subject to high temperatures and thermal gradients, with the requirement that they must maintain their geometric and structural integrity. A substantial increase in the capabilities of ceramic materials at the limits of temperatures and operational loads is being pursued, in order to use them in advanced hypersonic vehicles. Ultra-high temperature ceramics (UHTCs) are considered attractive candidates for nose cones and sharp leading edges of next generation hypersonic re-entry vehicles thanks to their high melting point, good stability at high temperature and high thermal and electrical conductivity. This project, funded by the UK’s Defence Science and Technology Laboratory (Dstl), aims at developing computational methods to assess damage and failure in UHTCs to aid in the design of laboratory tests, thus reducing time and costs associated with experiments. In fact, UHTC components may undergo creep and surface oxidation while operating at high temperature in aggressive environment, as well as fail prematurely due to thermal shock. It is therefore essential to be able to predict such phenomena to provide a powerful tool that can be useful for hypersonic vehicle design. A continuum damage mechanics-based model running as a custom user subroutine in the finite element (FE) software Abaqus is hereby proposed to account for damage due to creep and time-dependent material oxidation. Following an initial validation on a representative three point bend geometry to illustrate the methodology proposed to predict creep damage, a simple novel approach to estimate oxidation damage was incorporated in the user subroutine. Additionally, a microstructural model was introduced in the FE code to be able to treat grains and grain boundaries separately in the analysis, making it possible to simulate enhanced diffusion to grain boundaries. The same approach was also used to predict the heat flow, temperature distribution, phase transition and stress distribution during high heat flux laser tests and compared with experimental results.
New approaches for clustering time series data
Creators: name: Bakoben, Maha
Publisher: name: Imperial College London
Year: 2016

description: Time series data describe features of objects sequentially in time. The analysis of this data is useful in understanding the past and estimating the future. One of the promising methods in analysis of such data is cluster analysis which aims at finding underlying similarities, such that objects can be partitioned into clusters. Diverse implementations of this methodology are available. For example, clustering gene expression profiles in biology; clustering stock time series in finance; clustering daily temperature in meteorology and many others. Unlike standard data, the intrinsic features of the time series need to be considered in the analysis, such as serial dependence. This thesis takes a statistical approach in which the dynamic features are explained using appropriate time series models. The focus will be directed toward clustering of statistical model parameters. However, the inevitable uncertainty associated with parameter estimates is a critical issue that might negatively affect clustering in the parameter space. One of the main contributions of this thesis is the development of a new clustering approach that addresses this issue. Rigorous studies of the properties and performance of the new approach are provided. In addition, the computation of the proposed approach relies on Monte Carlo sampling, hence novel procedures are developed for this purpose. The time series clustering research is motivated and fully developed by a real data application of credit card behaviours. The problem is studied in the behavioural credit scorecards framework in which clustering of the credit account behaviours might assist in identifying distinct risk groups. We explore through logistic regression models the relationships between the behaviour clusters and the probability of default events.

description: We exclude hydrogen burning stars, of any mass above the hydrogen-burning limit and any metallicity, as significant contributors to the massive halos deduced from rotation curves to dominate the outer parts of spiral galaxies. We present and analyse images of 4 nearly edge-on bulgeless spiral galaxies (UGC711, NGC2915, UGC12426, UGC1459) obtained with ISOCAM (The CAMera instrument on board the Infrared Space Observatory) at 14.5micron and 6.75micron. Our sensitivity limit for detection of any diffuse infrared emission associated with the dark halos in these galaxies is a few tens of microJy per 6arcsec x 6arcsec pixel, with this limit currently set by remaining difficulties in modelling the non-linear behaviour of the detectors. All four galaxies show zero detected signal from extended non-disk emission, consistent with zero halo-like luminosity density distribution. The 95percent upper limit on any emission, for NGC2915 in particular, allows us to exclude very low mass main sequence stars (M > 0.08 Msun), and young brown dwarfs (< 1 Gyr) as significant contributors to dark matter in galactic halos. Combining our results with those of the Galactic microlensing surveys, which exclude objects with M < 0.01 Msun, excludes almost the entire possible mass range of compact baryonic objects from contributing to galactic dark matter.

description: For a given source and lens pair, there is a thin on-axis tube-like volume behind the lens in which the radiation flux from the source is greatly increased due to gravitational lensing. Any objects (such as dust grains) which pass through such a thin tube will experience strong bursts of radiation, i.e., Extreme Gravitational Lensing Events (EGLE). We study the physics and statistics of EGLE for the case in which finite source size is more important than shear. One of the several possible significant astrophysical effects is investigated with an illustrative calculation.

Biasing and the distribution of dark matter haloes

Publisher: name: arXiv
Year: 1998

description: In hierarchical models of gravitational clustering, virialized haloes are biased tracers of the matter distribution. As discussed by Mo & White (1996), this bias is nonlinear and stochastic. They developed a model which allows one to write down analytic expressions for the mean of the bias relation, in the initial Lagrangian, and the evolved, Eulerian spaces. We provide analytic expressions for the higher order moments as well. We also show how the Mo-White approach can be extended to compute the evolution, not just of the haloes, but of the dark matter distribution itself. The model predictions for the mean and scatter in the Eulerian bias relation, as well as for the Eulerian halo-mass and halo-halo correlation functions, are in reasonable agreement with numerical simulations of hierarchical gravitational clustering for haloes of a wide range of masses, whereas the predictions for the corresponding Lagrangian quantities are accurate only for massive haloes.

Elucidating the driving forces that control the structure of pentacene-based thin films
Creators: name: Kim, Dong Kuk
Publisher: name: Imperial College London
Year: 2023

description: Organic semiconductors have attracted significant interest due to their structural tuneability, low cost, ease of processing and desirable optical and electronic properties. The molecular orientation and order of organic semiconductors strongly influence their functional properties and consequently device performance. Among the organic semiconductors, pentacene, a small organic molecule with a well-defined crystal structure and attractive charge carrier mobility and singlet fission properties, is investigated as the model system. The relative geometry of pentacene molecules is known to influence its photophysical and electronic properties, which in hand governs its device applicability. An effective means to control molecular orientation is needed to optimise the functional properties of organic semiconductors and broaden the range of device applications possible. This thesis identifies structural templating and molecular mixing as strategies for controlling the molecular orientation and structure (up to a point) of organic small molecules. Copper iodide is identified as an effective templating layer for planar rod-like molecules and helicenes, which are a class of fused aromatic chiral molecules. Multimodal characterisation, including microscopy, spectroscopy and X-ray diffraction measurements, elucidate changes in molecular structure and uncover the underlying mechanisms of interaction and relaxation. For example, on copper iodide, pentacene adopts a flat-lying orientation, which is attributed to quadrupolar interactions between the pentacene partial charges and negatively charged copper iodide surface. Organic and inorganic templating layers are implemented to control the molecular orientation that can be easily transferred to a range of different organic molecules and device architectures. This thesis provides a methodology of effective molecular orientation control and characterisation that can be extended to a wider range of organic small molecules. This thesis extends our understanding of the role of polarity (substrate and molecule) in the control of molecular orientation and provides design strategies that are applicable to a wider range of aromatic systems.

description: Stability properties of gravitationally bound condensates composed of ultralight axionic Fuzzy Dark Matter (FDM) are studied. Previous work has shown that astrophysical collisions could make self-gravitating condensates structurally unstable, making them prone to collapse and decay; in the context of FDM, we reexamine the relevant timescales using the time-dependent variational method. We show that FDM condensates can be made unstable through gravitational interactions with central black holes, for black hole masses in a phenomenologically relevant range. Instability could also be stimulated by galaxy collisions. The subsequent decay takes place over a period lasting as long as many thousands of years. We also discuss the possible relevance of FDM condensates to understanding the composition of Ultracompact Dwarf (UCD) Galaxies. Future observation of extremely massive black holes in the central regions of UCDs can constrain this interpretation.
