description: We introduce the notion of crystallographic T-duality, inspired by the appearance of $K$-theory with graded equivariant twists in the study of topological crystalline materials. Besides giving a range of new topological T-dualities, it also unifies many previously known dualities, motivates generalisations of the Baum-Connes conjecture to graded groups, provides a powerful tool for computing topological phase classification groups, and facilitates the understanding of crystallographic bulk-boundary correspondences in physics.

description: Hybrid excitations, called polaritons, emerge in systems with strong light-matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in quantum optics. Here, we show the crucial role of the electronic component of polaritons in the magneto-transport of a cavity-embedded 2D electron gas in the ultrastrong coupling regime. We show that the linear dc resistivity is significantly modified by the coupling to the cavity even without external irradiation. Our observations confirm recent predictions of vacuum-induced modification of the resistivity. Furthermore, photo-assisted transport in presence of a weak irradiation field at sub-THz frequencies highlights the different roles of localized and delocalized states.

description: The project "Conservation for Sustainable Development in Central America", known as Olafo, at the Tropical Agriculture Research and Training Centre (CATIE) seeks to promote the sustainable use of local biological diversity by rural groups established in agricultural frontier zones in four Central American countries. A comparison of strategies employed in communities in Guatemala, Costa Rica and Panama shows that: i) systems analysis, as a conceptual framework, can be used to simultaneously consider development and conservation, two goals often considered contradictory; the formation of interdisciplinary teams provides opportunities to demystify technical issues by reconciling the perspectives of both the technicians and the communities; ii) the reinforcement and capacity-building of community organisations should be included as an objective not only to satisfy the basic development needs of a community, but also to provide skills to negotiate with different institutions — both private and public — on technical assistance and policy issues such as land tenure; iii) national institutions, contrary to general opinion, cannot, in the short term, allow for the continuation of these types of activities; iv) a working strategy at the community level should consider: • the identification of problems through existing formal local organisations as well as more informal family groups; the basic need of the local population for the intervention of external agents (e.g. technicians, NGOs and other non-local institutions); • the need for both technical and organisational training at a local level; • the identification of formal, informal and potential leaders within a community.

description: The detection of the binary neutron star GW170817 together with the observation of electromagnetic counterparts across the entire spectrum inaugurated a new era of multi-messenger astronomy. In this study we incorporate wavelength-dependent opacities and emissivities calculated from atomic-structure data enabling us to model both the measured lightcurves and spectra of the electromagnetic transient AT2017gfo. Best-fits of the observational data are obtained by Gaussian Process Regression, which allows us to present posterior samples for the kilonova and source properties connected to GW170817. Incorporating constraints obtained from the gravitational wave signal obtained by the LIGO-Virgo Scientific Collaboration, we present a $90\%$ upper bound on the mass ratio $q \lesssim 1.38$ and a lower bound on the tidal deformability of $\tildeΛ \gtrsim 197$, which rules out sufficiently soft equations of state. Our analysis is a path-finder for more realistic kilonova models and shows how the combination of gravitational wave and electromagnetic measurements allow for stringent constraints on the source parameters and the supranuclear equation of state.
The distance to NGC 6397 by M-subdwarf main-sequence fitting

description: Recent years have seen a substantial improvement both in photometry of low luminosity stars in globular clusters and in modelling the stellar atmospheres of late-type dwarfs. We build on these observational and theoretical advances in undertaking the first determination of the distance to a globular cluster by main-sequence fitting using stars on the lower main sequence. The calibrating stars are extreme M subdwarfs, as classified by Gizis (1997), with parallaxes measured to a precision of better than 10%. Matching against King et al's (1998) deep (V, (V-I)) photometry of NGC 6397, and adopting E_{B-V}=0.18 mag, we derive a true distance modulus of 12.13 +- 0.15 mag for the cluster. This compares with (m-M)_0=12.24 +- 0.1 derived through conventional main-sequence fitting in the (V, (B-V)) plane. Allowing for intrinsic differences due to chemical composition, we derive a relative distance modulus of delta (m-M)_0=2.58 mag between NGC 6397 and the fiducial metal-poor cluster M92. We extend this calibration to other metal-poor clusters, and examine the resulting RR Lyrae (M_V, [Fe/H]) relation.

description: This paper focuses on inverse problems to identify parameters by incorporating information from measurements. These generally ill-posed problems are formulated here in a probabilistic setting based on Bayes's theorem because it leads to a unique solution of the updated distribution of parameters. Many approaches build on Bayesian updating in terms of probability measures or their densities. However, the uncertainty propagation problems and their discretisation within the stochastic Galerkin or collocation method are naturally formulated for random vectors which calls for updating of random variables, i.e. a filter. Such filters typically build on some approximation to conditional expectation (CE). Specifically, the approximation of the CE with affine functions leads to the familiar Kalman filter which works best on linear or close to linear problems only. Our approach builds on a reformulation, which allows to localise the operator of the CE to the point of measured value. The resulting conditioned expectation (CdE) predicts correctly the quantities of interest, e.g. conditioned mean and covariance, even for general highly non-linear problems. The novel CdE allows straight-forward numerical integration; particularly, the approximated covariance matrix is always positive definite for integration rules with positive weights. The theoretical results are confirmed by numerical examples.

Impacts of deforestation on mosquito community dynamics
Creators: name: Brant, Hayley
Publisher: name: Imperial College London
Year: 2015

description: Human-induced land use changes, including deforestation, agricultural encroachment and urbanisation, have caused widespread change in the global distribution of organisms and caused considerable declines in biodiversity through loss of habitat. Oil palm is one of the most rapidly expanding crops in Southeast Asia, but the impact of this crop on mosquito distribution, behaviour and exposure potential has been poorly explored. Understanding these factors is essential for developing, optimising and evaluating novel control measures aimed at reducing disease-transmission. This thesis explored the effect of land use change along an anthropogenic disturbance gradient (primary forest, disturbed forest, highly disturbed forest, oil palm plantations and rural housing estates) in Sabah, Malaysia. The community composition of anthropogenic mosquitoes was separated across land use, with the biggest difference seen between primary forest and oil palm plantations. This was largely driven by medically important mosquitoes attracted to oil palm plantations. Differences in community composition were also seen in areas of rural housing in comparison to primary and disturbed forest sites, due to a high presence of the dengue vector, Stegomyia albopicta, in housing areas. A higher abundance of anopheline vectors were found landing on humans in the disturbed forest and oil palm plantations then primary forest. This thesis found no difference between highly disturbed forest and oil palm plantation sites. This thesis also investigated the host-seeking behaviour of simian malaria vectors, by carrying out human landing catches at ground and canopy level across land use. Results demonstrated the potential ability of one of the vectors, Anopheles balabacensis, to transmit the simian malaria (Plasmodium knowlesi) between canopy-dwelling simian hosts and ground-dwelling humans, and that anthropogenic disturbance increases the abundance of the disease vector. Finally, this thesis investigated the use of different marking methods and the need for an improved dispersal experiment to be carried out.
Understanding the variability in vehicle dynamics and emissions at urban obstacles
Creators: name: Thiyagarajah, Aravinth
Publisher: name: Imperial College London
Year: 2015

description: Roadworks are a feature of the road network that can cause vehicles to deviate from their desired speed or trajectory. This may negatively impact traditional measures of network performance such as travel time, or result in changes to tailpipe emission rates. The impact of roadworks on tailpipe emission rates is of interest due to the harmful pollutants that are released during the combustion process. Pollutants such as nitrogen oxides (NOx) are toxic to humans, and carbon dioxide (CO2) is a greenhouse believed to influence human-induced global climate change. In order to investigate methods of reducing the environmental impact of roadworks and other obstacles in the road network, modelling tools may be used. However, it is essential that the tools are appropriate for modelling these features of the road network. In order to assess the suitability of existing traffic and emission modelling tools, an understanding of the variability in vehicle dynamics and emissions at urban obstacles is first required. In this thesis, a dataset that contains real-world tailpipe emissions and vehicle dynamics data, from vehicles in the vicinity of urban obstacles such as roadworks, is assembled. This is achieved using a portable emission measurement system (PEMS) and a high-resolution trajectory monitoring platform developed as part of this research. Through analysis of the acceleration behaviour and tailpipe emission rates at different urban obstacles and from different vehicles, an understanding of the variability is formed. The findings from the analysis of behaviours observed in the vicinity of urban obstacles are then used to adapt existing traffic and emissions modelling tools. The error between measured and modelled emissions is shown to reduce from over 30% to under 12% for CO2 emissions. Based on the findings of a roadworks case study, recommendations are made to policy makers and the modelling community.

description: Optical properties of nanoparticle assemblies reflect distinctive characteristics of their building blocks and spatial organization, giving rise to emergent phenomena. Integrated experimental and computational studies have established design principles connecting the structure to properties for assembled clusters and superlattices. However, conventional electromagnetic simulations are too computationally expensive to treat more complex assemblies. Here we establish a fast, materials agnostic method to simulate the optical response of large nanoparticle assemblies incorporating both structural and compositional complexity. This many-bodied, mutual polarization method resolves limitations of established approaches, achieving rapid, accurate convergence for configurations including thousands of nanoparticles, with some overlapping. We demonstrate these capabilities by reproducing experimental trends and uncovering far- and near-field mechanisms governing the optical response of plasmonic semiconductor nanocrystal assemblies including structurally complex gel networks and compositionally complex mixed binary superlattices. This broadly applicable framework will facilitate the design of complex, hierarchically structured, and dynamic assemblies for desired optical characteristics.
The role of extrinsic noise in biomolecular information processing systems: an in silico analysis
Creators: name: Lenive, Oleg
Publisher: name: Imperial College London
Year: 2014

description: The intrinsic stochasticity of biomolecular systems is a well studied phe- nomenon. Less attention has been paied to other sources of variability, so called extrinsic noise. While the precise definition of extrinsic noise de- pends on the system in question, it affects all cells and its significance has been demonstrated experimentally. Information theory provides a rigorous mathematical framework for quan- tifying both the amount of information available to a signalling system and its ability to transmit this information. Intracellular signal transduction re- mains a relatively unexplored frontier for the application of information theory. In this thesis, we rely on a metric called mutual information to quantify in- formation flow in models of biochemical signalling systems. After briefly discussing the theoretical background and some of the practical difficulties of estimating mutual information in Chapter 2, we apply it in the context of simplified models of intracellular signalling, referred to as motifs. Using a comprehensive set of two-node motifs we explore the effects of extrin- sic noise, model parameters and various combinations of interaction, on the system’s ability to transmit information about an input signal, repre- sented by a telegraph process. Our results illustrate the importance of the system’s response time and demonstrate a trade-off in transmitting infor- mation about the current state of the input or its average intensity over a period of time. In Chapter 4, we address the problem of determining the magnitude of ex- trinsic noise in the presence of intrinsic stochasticity. Using the Approxi- mate Bayesian Computation - sequential Monte Carlo algorithm, together with published experimental data, we infer parameters describing extrinsic noise in a model of E. coli gene expression. Lastly, in Chapter 5, we construct and analyse models of bacterial two- component signalling, bringing together insights gleaned from earlier work. The results show how the abundances of different molecular species in the system may transmit information about the input signal despite its stochas-tic nature and considerable variation in the numbers of protein molecules present.

Mode Identification of the Slowly Pulsating F0V Star V398 Aurigae (9 Aur)

description: We have investigated the F0V star V398\,Aurigae (= 9 Aur) under the assumption that it is undergoing non-radial gravity mode oscillations and that the two principal periods given by Krisciunas et al. (1995) are correct. We find that the two periods are manifestations of an $\ell=3, |m|=1$ spheroidal mode and its toroidal corrections due to the rotation of the star. As far as we know, this is the first detection of toroidal correction terms in a real star. The two modes probably are the result of rotational splitting. Our analysis provides for the first time a physical explanation of certain characteristics of the observed behavior of the star. The amplitude of the radial part of the pulsation for $f_1 = 0.795$\,d$^{-1}$ is a factor of 4 larger than the one for $f_2 = 0.346$\,d$^{-1}$. Since the photometric variability is determined mostly by temperature variations, which in turn are determined by the radial part of the pulsation, the photometric variability is dominated by the mode with frequency $f_1$. On the other hand, $f_2$ is the more pronounced one in all three spectroscopic moment variations (including the radial velocity), reflecting that the transverse displacement of $f_2$, and not the one of $f_1$, dominates the velocity behavior.

Black Hole Mergers From Globular Clusters Observable by LISA II: Resolved Eccentric Sources and the Gravitational Wave Background

description: In paper I of this series we showed that a large percentage of the binary black hole (BBH) mergers that form through dynamical interactions in globular clusters will have significant eccentricity in the ~10^{-3}-10^{-1} Hz LISA band. In this work we quantify the evolution of these highly eccentric binaries through the LISA and LIGO bands, and compute the stochastic gravitational wave background from the merging, eccentric population. We find that the population of BBHs that merge in-between three-body encounters inside their cluster (~50% of all cluster-formed BBH mergers) will have measurable eccentricity for their entire lifetime in the LISA band. The population of BBHs that merge during three-body encounters (~5% of all cluster-formed BBH mergers), will be detectable by LIGO with eccentricities of e~0.1. The gravitational wave background from dynamically assembled BBHs encodes a characteristic bump due to the high initial eccentricities of these systems. The location and amplitude of this bump depends on globular cluster properties.

Cepheid and Tip of the Red Giant Branch Distances To the Dwarf Irregular Galaxy IC10

description: We present color-magnitude diagrams and luminosity functions of stars in the nearby galaxy IC 10, based on VI CCD photometry acquired with the COSMIC prime-focus camera on the Palomar 5m telescope. The apparent I-band luminosity function of stars in the halo of IC 10 shows an identifiable rise at I~21.7 mag. This is interpreted as being the tip of the red giant branch (TRGB) at M_V~-4 mag. Since IC 10 is at a very low Galactic latitude, its foreground extinction is expected to be high and the uncertainty associated with that correction is the largest contributor to the error associated with its distance determination. Multi-wavelength observations of Cepheid variable stars in IC 10 give a Population I distance modulus of 24.1 +- 0.2 mag, which corresponds to a linear distance of 660 +- 66 kpc for a total line-of-sight reddening of E(B-V) = 1.16 +- 0.08 mag, derived self-consistently from the Cepheid data alone. Applying this Population I reddening to the Population II halo stars gives a TRGB distance modulus of 23.5 +- 0.2 mag, corresponding to 500 +- 50 kpc. We consider this to be a lower limit on the TRGB distance. Reconciling the Cepheid and TRGB distances would require that the reddening to the halo is $Δ$E(B-V) = 0.31 mag lower than that into the main body of the galaxy. This then suggests that the Galactic extinction in the direction of IC10 is (B-V) ~ 0.85.
Theory of charge storage in nanostructured electrodes
Creators: name: Rochester, Christopher
Publisher: name: Imperial College London
Year: 2015

description: The use of nanostructured electrodes in supercapacitor design have the potential to in- crease both the specific capacitance, via the superionic effect, and the surface electrode interfacial area optimising the energy stored in such a device. When this increase in specific capacitance was first rationalised the electrodes that formed the supercapacitor were assumed to be ideally metallic. Accordingly, interionic interactions between coun- terions are exponentially screened by metallic electrons. This allows a denser packing of counter charge than what one would usually assume possible, which in turn leads to an increased specific capacitance. This was named the superionic effect. Modern nanoporous electrodes are predominantly made of carbon materials and are not ideally metallic. To test the applicability of the superionic state to an electrode constructed of non-ideal ma- terials we study Coulomb interaction of charges in cylindrical and slit pores that allow finite electric field penetration into the pore walls. In both geometries the screening is found to be subtly different than in metallic nanopores, but still strong enough to sup- port realization of the superionic state in such pores. Furthermore, the screening is found to be strong enough to neglect long range interactions between ions packed into these pores. Motivated by this we develop several nearest neighbour lattice models of charge storage for electrodes consisting of many similar cylindrical pores wetted with an ionic liquid. Finally, we present a theoretical study of structural deformation that has been seen to occur in carbon electrodes containing pores that are comparable in size to the size of a charging ion. Our model shows qualitative agreement with the features of the experimentally observed expansion caused by variation of electrode potential.
Ages and Metallicities of Young Globular Clusters in the Merger Remnant NGC 7252

description: UV-to-visual spectra of eight young star clusters in the merger remnant and protoelliptical galaxy NGC 7252, obtained with the Blanco 4-m telescope on Cerro Tololo, are presented. These clusters lie at projected distances of 3-15 kpc from the center and move with a velocity dispersion of 140+/-35 km/s in the line of sight. Seven of the clusters show strong Balmer absorption lines in their spectra [EW(H-beta)= 6-13 Angstrom], while the eighth lies in a giant HII region and shows no detectable absorption features. Based on comparisons with model-cluster spectra by Bruzual & Charlot (1996) and Bressan, Chiosi, & Tantalo (1996), six of the absorption-line clusters have ages in the range of 400-600 Myr, indicating that they formed early on during the recent merger. These clusters are globular clusters as judged by their small effective radii and ages corresponding to ~100 core crossing times. The one emission-line object is <10 Myr old and may be a nascent globular cluster or an OB association. The mean metallicities measured for three clusters are solar to within +/-0.15 dex, suggesting that the merger of two likely Sc galaxies in NGC 7252 formed a globular-cluster system with a bimodal metallicity distribution. Since NGC 7252 itself shows the characteristics of a 0.5-1 Gyr old protoelliptical, its second-generation solar-metallicity globulars provide direct evidence that giant ellipticals with bimodal globular-cluster systems can form through major mergers of gas-rich disk galaxies.

description: We study an accretion disc with a hot continuous corona. We assume that the corona itself accretes and therefore it is powered directly by the release of the gravitational energy and cooled by radiative interaction with the disc. We consider the vertical structure of such a corona and show that the radial infall is accompanied by strong vertical outflow. Such a model has two important consequences: (i) at a given radius the corona forms only for accretion rate larger than a limiting value and the fraction of energy dissipated in the corona decreases with increasing accretion rate, and (ii) the disc spectra are significantly softer in the optical/UV band in comparison with the predictions of standard accretion discs due to the mass loss and the decrease of internal dissipation in the disc. Both trends correspond well to the mean spectra of radio quiet AGN and observed luminosity states in galactic black hole candidates.

Characterization of the genetic architecture of dilated cardiomyopathy using families and cohorts
Creators: name: Mazzarotto, Francesco
Publisher: name: Imperial College London
Year: 2016

description: Cardiomyopathies are the leading cause of heart transplantation in the developed world, and dilated cardiomyopathy accounts for an important proportion of all heart failure cases in large clinical trials. In spite of a strong genetic basis for dilated cardiomyopathy being demonstrated widely in the past two decades, 60% of familial cases remain unexplained. Dilated cardiomyopathy is characterized by marked genetic heterogeneity, with more than 60 individual genes reported to cause the disease, yet only one (TTN) explaining more than 10% of cases. Here, high-throughput sequencing data, advanced imaging techniques and bioinformatics analyses were used to dissect the genetic architecture of dilated cardiomyopathy, by measuring the contribution of single genes and multi-genic variation on disease risk and severity, and performing gene and variant discovery in affected families. Burden testing (using bespoke software developed in the R programming language for this study) and regression modelling were used to examine the genetic determinants of disease by comparing a cohort of disease cases (n=332) to ethnically matched, phenotypically characterised healthy controls (n=319). This produced a measure of the contribution of each gene to dilated cardiomyopathy, taking into account the background variation rate in the general population. Analyses of multi-genic interactions were also performed, and having detected the signature of additive effects of variation in multiple genes on both disease likelihood and severity, further analyses were performed to identify specific gene-gene interactions in causing dilated cardiomyopathy. Subsequently, variant prioritisation strategies were developed to identify, from whole-exome sequencing data, possible genetic causes of an unexplained and very severe form of early-onset dilated cardiomyopathy segregating in a family. This led to the identification of new candidate genes, which might contribute towards a genetic diagnosis in the analysed family and to new insights into the pathogenesis of dilated cardiomyopathy. Preparatory work in developing variant prioritisation pipelines from whole-exome sequencing data had been performed earlier, on families affected with various inherited arrhythmia syndromes.

The presentation delves into the current challenges and opportunities for Higher Education brought about by Artificial Intelligence, contrasting two distinct futures shaped by diverging digital political economies: one dystopian and the other utopian. It outlines how these scenarios could unfold based on current trends. After exploring the implications of each scenario, the presentation proposes a comprehensive global agenda.

Correlation Between Gas and Dust in Molecular Clouds: L977

description: We report observations of the J =(1--0) C18O molecular emission line toward the L977 molecular cloud. To study the correlation between C18O emission and dust extinction we constructed a Gaussian smoothed map of the infrared extinction measured by Alves et al. (1998) at the same angular resolution (50'') as our molecular--line observations. This enabled a direct comparison of C18O integrated intensities and column densities with dust extinction over a relatively large range of cloud depth (2 < Av < 30 mag) at 240 positions inside L977. We find a good linear correlation between these two column density tracers for cloud depths corresponding to Av < ~10 magnitudes. For cloud depths above this threshold there is a notable break in the linear correlation. Although either optically thick C18O emission or extremely low (Tex < 5 K) excitation temperatures at high extinctions could produce this departure from linearity, CO depletion in the denser, coldest regions of L977 may be the most likely cause of the break in the observed correlation. We directly derive the C18O abundance in this cloud over a broad range of cloud depths and find it to be virtually the same as that derived for IC 5146 from the data of Lada et al. (1994). In regions of very high extinction (Av > 10 mag), such as dense cores, our results suggest that C18O would be a very poor tracer of mass. Consequently, using C18O as a column density tracer in molecular clouds can lead to a 10 to 30% underestimation of overall cloud mass. We estimate the minimum total column density required to shield C18O from the interstellar radiation field to be 1.6 +/- 0.5 magnitudes of visual extinction.

«Je vous prie de dire mille choses de ma part au respectable Mr Séguier, dites-lui que j'ai ramassé peu de choses dans mon voyage des Pyrénées, j'étais trop pressé. Je n'ai pour ainsi dire pu faire que mon inspection, considérer en gros de belles horreurs et ameuter une correspondance de laquelle j'espère ce que je n'ai pu me procurer. Je compte lui écrire incessamment. Je cherche une occasion pour lui envoyer un fatras de graines et d'oignons de plantes. Je lui destine un morceau de marbre petit échantillon dont il n'a certainement point vu. Il lui fera plaisir. Il est indicatif des bélemnites, il désigne une indication que la mer a couvert les Pyrénées; peut-être est-ce aussi un autre animal; ce morceau vaut tout [fol. 107v]ce que j'ai pu ramasser, je lui réserve aussi une pierre de granite dans laquelle il y a un petit monde incrusté et pétrifié, du moins c`en est la forme. Donnez lui seulement cet avant goût; ces morceaux sont de la forêt d'Aps. Présentez-lui, je vous prie, mes respects».

A Monsieur Séguier

A Nîsmes.

A flexible tool design and integrated modelling techniques for springback compensation in creep-age forming
Creators: name: Lam, Aaron C L
Publisher: name: Imperial College London
Year: 2015

description: This thesis presents the development of ad-hoc experimental and integrated modelling techniques for springback compensation in creep-age forming (CAF). A test programme is presented which describes the material and workpiece information and the test plans for the experimental evaluation of the creep-ageing and springback behaviour of aluminium alloy 7B04-T651 under 115 oC. Experimental results from the creep-ageing and tensile tests were used to determine a CAF material model for the alloy. A flexible tool design has been proposed and a laboratory-scale prototype has been delivered and used to perform the CAF tests in this research. The determined CAF material model and geometry of the flexible tool design were treated as input and used to construct a CAF process model using finite element (FE) method. Comparisons between final deflections of FE-simulated and experimentally formed plates validated the springback predictive ability of the FE process model. The model was eventually employed to model springback-compensated tool shapes and using the modelled tool shapes to perform CAF tests have produced formed plates that have an average 0.81±0.14 mm of maximum absolute vertical difference from target shape. CAF can now be used to produce accurately shaped panel components in a laboratory environment using the equipment and techniques developed in this research.
Spectral Functions of One-Dimensional Systems with Correlated Disorder

description: We investigate the spectral function of Bloch states in an one-dimensional tight-binding non-interacting chain with two different models of static correlated disorder, at zero temperature. We report numerical calculations of the single-particle spectral function based on the Kernel Polynomial Method, which has an $\mathcal{O}(N)$ computational complexity. These results are then confirmed by analytical calculations, where precise conditions were obtained for the appearance of a classical limit in a single-band lattice system. Spatial correlations in the disordered potential give rise to non-perturbative spectral functions shaped as the probability distribution of the random on-site energies, even at low disorder strengths. In the case of disordered potentials with an algebraic power-spectrum, $\propto\left|k\right|^{-α}$, we show that the spectral function is not self-averaging for $α\geq1$.

description: As a statistical measure to quantify the topological structure of the large-scale structure in the universe, the genus number is calculated for a number of non-Gaussian distributions in which the density field is characterized by a nontrivial function of some Gaussian-distributed random numbers. As a specific example, the formulae for the lognormal and the chi-square distributions are derived and compared with the results of $N$-body simulations together with the previously known formulae for the Gaussian distribution and second-order perturbation theory. It is shown that the lognormal formula fits most of the simulation data the best.

Quantification of uncertainty in probabilistic safety analysis
Creators: name: El-Shanawany, Ashraf Ben Mamdouh
Publisher: name: Imperial College London
Year: 2016

description: This thesis develops methods for quantification and interpretation of uncertainty in probabilistic safety analysis, focussing on fault trees. The output of a fault tree analysis is, usually, the probability of occurrence of an undesirable event (top event) calculated using the failure probabilities of identified basic events. The standard method for evaluating the uncertainty distribution is by Monte Carlo simulation, but this is a computationally intensive approach to uncertainty estimation and does not, readily, reveal the dominant reasons for the uncertainty. A closed form approximation for the fault tree top event uncertainty distribution, for models using only lognormal distributions for model inputs, is developed in this thesis. Its output is compared with the output from two sampling based approximation methods; standard Monte Carlo analysis, and Wilks’ method, which is based on order statistics using small sample sizes. Wilks’ method can be used to provide an upper bound for the percentiles of top event distribution, and is computationally cheap. The combination of the lognormal approximation and Wilks’ Method can be used to give, respectively, the overall shape and high confidence on particular percentiles of interest. This is an attractive, practical option for evaluation of uncertainty in fault trees and, more generally, uncertainty in certain multilinear models. A new practical method of ranking uncertainty contributors in lognormal models is developed which can be evaluated in closed form, based on cutset uncertainty. The method is demonstrated via examples, including a simple fault tree model and a model which is the size of a commercial PSA model for a nuclear power plant. Finally, quantification of “hidden uncertainties” is considered; hidden uncertainties are those which are not typically considered in PSA models, but may contribute considerable uncertainty to the overall results if included. A specific example of the inclusion of a missing uncertainty is explained in detail, and the effects on PSA quantification are considered. It is demonstrated that the effect on the PSA results can be significant, potentially permuting the order of the most important cutsets, which is of practical concern for the interpretation of PSA models. Finally, suggestions are made for the identification and inclusion of further hidden uncertainties.
