Characterisation and Calibration of ZEPLIN III - A Dark Matter Detector
Creators: name: Thorne, Claire
Publisher: name: Imperial College London
Year: 2009

description: The ZEPLIN III liquid xenon dark matter detector is designed to potentially discover the WIMP - a supersymmetric galactic dark matter candidate. This thesis presents experimental results of the ZEPLIN III commissioning studies, in preparation for the first and second underground science runs. Data acquired on the surface, at the Imperial College London laboratories, were used to characterise the instrument’s response in terms of light yield (LY) and single photoelectron (SPE) spectra. A zero-field LY was measured as 7.42±0.37 phe/keV and 18.12±0.91 phe/keV in dedicated single- and dual-phase high yield configurations, respectively, consistent with Monte Carlo simulations. Mean SPE measured pulse areas ranged from 41.78±1.55 Vps to 52.37±1.59 Vps, depending on the method employed. A 3-D position reconstruction was verified and, significantly, no evidence of a potentially-contaminating background -population was observed. This study directly lead to critical development of the DAQ software and hardware configuration. The PMT array was confirmed as responsive and, crucially, the particle discrimination principle was demonstrated. Zero-field LYs of (4.6-4.7) ±0.5 phe/keV were recovered from the centre of the chamber, exceeding simulation predictions. With-field (3.01 kV/cm in the liquid) LYs of (1.2-1.8) ±0.3 phe/keV from the liquid scintillation (S1) and an electroluminescence yield (S2) of (98-140) ±35 phe/keV from the gas phase were also determined. ZEPLIN III was deployed in the Boulby Underground Laboratory, UK and demonstrated successful operation at high field (up to 3.79 kV/cm in the liquid), in situ. An alternative Poisson method for obtaining single photoelectron distributions was developed by the ZEPLIN collaboration. The origin of long- events in surface data was investigated and ultimately resolved as an artefact of early versions of the data reduction software. An S1 zero-field LY of 4.72±0.10 phe/keV, obtained with a 57Co external source, was recovered for the centre of the chamber. The instrument’s energy resolution was evaluated and a novel parameterisation approach, developed by the author, yielded sigma=1.08±0.06 p E(keV ) with a dominant stochastic term. A ‘flat-fielding’ method was established, proving to minimise the resolution significantly, yielding 8.6% and 7.3% for S1 and S2, respectively, in the fiducialised anti-correlated energy channel. This flat-fielding recipe, along with construction of the light collection correction matrices, formed the basis of the final procedures subsequently applied to first science run data-sets.

description: This paper presents the first dynamic predictive analysis for data store applications under weak isolation levels, called Isopredict. Given an observed serializable execution of a data store application, Isopredict generates and solves SMT constraints to find an unserializable execution that is a feasible execution of the application. Isopredict introduces novel techniques that handle divergent application behavior; solve mutually recursive sets of constraints; and balance coverage, precision, and performance. An evaluation on four transactional data store benchmarks shows that Isopredict often predicts unserializable behaviors, 99% of which are feasible.

Environmental Impacts of and Material Recovery from Biodegradable Waste
Creators: name: Gómez, Miguel Gabriel Cebrián
Publisher: name: Imperial College London
Year: 2009

description: The environmental impact of biodegradable waste has resulted in legislative drivers that are designed primarily to reduce the impacts arising from (a) pathogens in the waste, (b) gaseous emissions of carbon dioxide and methane, and (c) the effects of biodegradation in landfill sites on leachates to groundwater. These drivers are considered in this research under three applications: (i) the development of a sustainable technology for the treatment of food wastes to obtain a high quality compost product in a closed-loop situation within a single premises, (ii) the development of a programme to assess the environmental impacts and carbon footprints of food waste treatment options and of other secondary recovery processes, and (iii) the development of a methodology to assess the effects of landfill leachate on groundwaters resulting from deleterious landfill practices and management. Technology to overcome the challenges associated with the conversion of food waste to compost has been developed. The resulting in-vessel composting process produces a high quality compost that meets the highest BSI PAS 100 standard. The key factors in the methodology are the rapid transfer of food waste from the kitchen to composter, the efficient maceration and dewatering of the feedstock, optimisation of the C:N ratio, and the achievement of temperatures high enough to destroy pathogens. The fundamentals of the concept of benchmarking was developed in this work as part of a study to permit the determination of carbon dioxide savings in secondary metal recovery, and extended to carbon footprinting of alternative processes to landfill of food waste to permit a comparison of alternative treatments of food waste. The in-vessel composting methodology described in this work compares favourably with the alternative methods of food waste treatment. A computer software programme, HEDAS, for the statistical analysis of landfill monitoring data to predict borehole behaviour, has been developed. The programme permits assessment of the reliability of the data and ultimately determines the extent of groundwater contamination. In the course of the development of the software, a novel concept was used to determine the best applicable experimental standard deviation (BAESD) to be used to assess the reliability of individual borehole and analyte data. The BAESD is used with the measured standard deviations for individual boreholes and analytes to produce a reliability rating for the individual borehole and analyte. These ratings effectively measure the analytical data against the most stable boreholes at the site and provide viable indicators of step changes in concentration or other anomalies. HEDAS was developed using historical data from the UK Environment Agency’s Thames region, and is now used as their standard for assessing monitored data at landfill sites. The application of HEDAS has now been extended from groundwater and leachate analysis to landfill gas emissions.

description: The presence of extreme horizontal branch (EHB) and blue hook stars in some Galactic globular clusters (GGCs) constitutes one of the remaining mysteries of stellar evolution. In this paper, we focus on $ω$ Cen, a peculiar, massive GGC that hosts multiple stellar populations. We use non-LTE model atmospheres to derive atmospheric parameters (Teff, log g and N(He)/N(H)) and spectroscopic masses for 152 EHB stars in the cluster. This constitutes the largest spectroscopic sample of EHB stars ever analyzed in a GGC and represents ~20% of the EHB population of $ω$ Cen. We also search for close binaries among these stars based on radial velocity variations. Our results show that the EHB population of $ω$ Cen is divided into three spectroscopic groups that are very distinct in the Teff - helium abundance plane. The majority of our sample consists of sdOB stars that have roughly solar or super-solar atmospheric helium abundances. It is these objects that constitute the blue hook at $V >$ 18.5 mag in the $ω$ Cen color-magnitude diagram. Interestingly, the helium-enriched sdOBs do not have a significant counterpart population in the Galactic field. Another major difference between the EHB stars in $ω$ Cen and the field is the fraction of close binaries. From our radial velocity survey we identify two binary candidates and estimate an EHB close binary fraction of ~5% in $ω$ Cen. This low fraction is in line with findings for other GGCs, but in sharp contrast to the situation in the field, where around 50% of the sdB stars reside in close binaries. Finally, the mass distribution derived is very similar for all three spectroscopic groups, however the average mass (0.38 Msun) is lower than that expected from stellar evolution theory. While this mass conundrum has previously been noted for EHB stars in $ω$ Cen, it so far appears to be unique to that cluster.

Modelling and prediction of foam structure
Creators: name: Wang, Yingjie
Publisher: name: Imperial College London
Year: 2009

description: The primary objective of this thesis is to explore the relationship between the surface and underlying structure of dry foams. This relationship is important for both research and industry because the surface film size distribution is typically the only information available in opaque foams when referring to the underlying bubble size distribution. This study is carried out by simulating foams with free surfaces. Firstly, the method of simulating 3D dry foams with free surfaces is presented. The simulation method is verified for foams with uniform bubble sizes by comparing their simulation results to experimental values reported in literature. The validity of the method and its ability to accurately model the structure of both surface and internal bubbles is demonstrated by the excellent agreement between the experimental study and the simulation results. Secondly, the simulation results are shown for the relationship between the surface film size distribution and the surface bubble size distribution. The results show that, for a given surface bubble size, there is a distribution of possible surface film sizes. However, for the range of polydispersity used in this thesis, the distribution of the ratio of film size to the size of bubble to which it is attached is found to be independent of the underlying bubble size distribution. A functional form of this relationship is obtained by nonlinear regression. Based on the functions obtained, the surface film size distributions can be computed using the underlying surface bubble size distribution. This is the inverse of what is acquired and therefore a numerical procedure for obtaining the surface bubble size distributions using the corresponding surface film size distribution is developed. This method is demonstrated to accurately reproduce the results from the full structural foam simulations.

description: We consider the model of a massless charged scalar field, in (2+1) dimensions, with a self interaction of the form $lambda (ϕ^* ϕ)^3$ and interacting with a Chern Simons field. We calculate the renormalization group $β$ functions of the coupling constants and the anomalous dimensions $γ$ of the basic fields. We show that the interaction with the Chern Simons field implies in a $β_λ$ which suggests that a dynamical symmetry breakdown occurs. We also study the effect of the Chern Simons field on the anomalous dimensions of the composite operators $(ϕ^* ϕ)^n$, getting the result that their operator dimensions are lowered.

description: We used optical imaging and spectroscopic data to derive substructure estimates for local Universe ($z < 0.11$) galaxy clusters from two different samples. The first was selected through the Sunyaev-Zel'dovich (SZ) effect by the Planck satellite and the second is an X-ray selected sample. In agreement to X-ray substructure estimates we found that the SZ systems have a larger fraction of substructure than the X-ray clusters. We have also found evidence that the higher mass regime of the SZ clusters, compared to the X-ray sample, explains the larger fraction of disturbed objects in the Planck data. Although we detect a redshift evolution in the substructure fraction, it is not sufficient to explain the different results between the higher-z SZ sample and the X-ray one. We have also verified a good agreement ($\sim$60$\%$) between the optical and X-ray substructure estimates. However, the best level of agreement is given by the substructure classification given by measures based on the brightest cluster galaxy (BCG), either the BCG$-$X-ray centroid offset, or the magnitude gap between the first and second BCGs. We advocate the use of those two parameters as the most reliable and cheap way to assess cluster dynamical state. We recommend an offset cut of $\sim$0.01$\times$R$_{500}$ to separate relaxed and disturbed clusters. Regarding the magnitude gap the separation can be done at $Δm_{12} = 1.0$. The central galaxy paradigm (CGP) may not be valid for $\sim$20$\%$ of relaxed massive clusters. This fraction increases to $\sim$60$\%$ for disturbed systems.

On dissipation intermittency and its modelling in terms of turbulence-chemistry interactions
Creators: name: Vaishnavi, Pankaj Yograj
Publisher: name: Imperial College London
Year: 2009

description: A key challenge in combustion research is to model complex turbulence-chemistry interactions during extinction and re-ignition of non-premixed ames. These are caused when the scalar dissipation, , is above (or below) certain limits such that the diffusive temperature ux from the ame is much larger (or smaller) than chemical heat-release. is characterised by its small-scale intermittency, i.e. large uctuations in are frequent and localised in space. This behaviour severely constrains its resolvability and has implications for modelling extinction/re-ignition processes. Scalar eld statistics from the direct numerical simulation (DNS) database of a spatially-evolving, turbulent jet ame with multi-step chemistry by Pantano (2004) are studied using three different approaches, namely analysis of dissipation-spectra, direct investigation of dissipation contours and spatial filtering of the instantaneous dissipation signals. Out of these the spatial filtering method is found to be most suited for capturing the intermittent dissipation length scales and an Reδ-1 scaling is proposed for 'adequate' -resolution in turbulent jet ame experiments/simulations. Furthermore, a Multiple Mapping Conditioning (MMC) approach with two reference variables is used to model extinction/re-ignition in inhomogeneous turbulent jet ames. A new sub-model for the convective velocity term is employed that does not need to presume Gaussian statistics and consistent closures for MMC drift and diffusion coefficients are derived. Effect of temperature uctuations on scalar diffusivity is also accounted for. Joint scalar PDFs, conditional dissipation and conditional species predictions from MMC, and also conditional species concentrations from conventional singly- and doubly-conditioned moment closure (CMC1 and CMC2), are assessed against the Pantano DNS database. CMC1 expectedly over-predicts extinction and does not capture re-ignition, whereas extinction and re-ignition effects on species concentrations (including atomic H-radical) are captured satisfactorily using CMC2 and MMC. However, MMC scores over CMC2 because models for the joint scalar PDF evolution and conditional dissipation are self-contained in the former.

description: The Chesapeake Farm Buildings Survey was organized in the Fall of 1980 as a long-term effort to record seriously threatened agricultural buildings in the Tidewater region. The initial group of eight participants has expanded to roughly fifteen architectural historians, folklorists, and social historians. Bi-monthly meetings are held in Annapolis, Williamsburg, and Richmond. Buildings are identified and recorded by participants according to significance, likelihood of destruction, and accessibility. Working individually or in teams, members bring their work to the meetings for discussion with the rest of the group. Because of the variety of professional interests represented within the group, and because members are geographically scattered from northern Delaware to North Carolina, the recorded buildings reflect a broad spectrum of origin and use. Report also includes a topographical description and overview of cultural resources at the Adelphi Laboratory Center.

Novel approaches to statistical shape modelling of bone
Creators: name: Tardugno, Angelo
Publisher: name: Imperial College London
Year: 2010

description: The femur is the longest bone in the human body and serves the important purposes of load-bearing and allowing bipedal locomotion. Accurate modelling of the variation in shape within the healthy adult population can be useful for a variety of applications: from the mere anatomical description of its features, in order to better understand its function, to more complex tasks such as pathology detection or surgical planning. Statistical Shape Modelling (SSM) is a well-established technique that enables to capture the variability within a set of training shapes and describes it with a reduced set of variables. The aim of this thesis is to evaluate the performance of a SSM based on a point cloud representation of shape, and introduce and test subsequent improvements to the modelling process that can increase its clinical relevance and scope of application. The standard approach to SSM employs a dimension-reducing technique, generally by means of Principal Component Analysis (PCA). However, this approach favours the compactness of the model, thus not focusing on other aspects that may be more relevant to clinical practice. Although rotation of the principal components is commonly performed as a post-processing step in statistical analysis involving PCA, it is not routinely applied in SSM. By applying this class of rotation, the components' effects are more localised, allowing a better interpretation, understanding and classification of pathological deformities. Among other possible representations, the Medial Axis Transform (MAT) could offer a further insight into shape modelling, since it allows the information about thickness to be decoupled from the rest of the shape. SSMs based on this representation can lead to a di erent perspective on the understanding of femoral anatomy and function,and can also enable the reconstruction of the complete anatomy starting from a reduced set of features, with diverse applications in the elds of surgical planning, forensic science and paleontology.

Robust equalization of multichannel acoustic systems
Creators: name: Zhang, Wancheng
Publisher: name: Imperial College London
Year: 2010

description: In most real-world acoustical scenarios, speech signals captured by distant microphones from a source are reverberated due to multipath propagation, and the reverberation may impair speech intelligibility. Speech dereverberation can be achieved by equalizing the channels from the source to microphones. Equalization systems can be computed using estimates of multichannel acoustic impulse responses. However, the estimates obtained from system identification always include errors; the fact that an equalization system is able to equalize the estimated multichannel acoustic system does not mean that it is able to equalize the true system. The objective of this thesis is to propose and investigate robust equalization methods for multichannel acoustic systems in the presence of system identification errors. Equalization systems can be computed using the multiple-input/output inverse theorem or multichannel least-squares method. However, equalization systems obtained from these methods are very sensitive to system identification errors. A study of the multichannel least-squares method with respect to two classes of characteristic channel zeros is conducted. Accordingly, a relaxed multichannel least- squares method is proposed. Channel shortening in connection with the multiple- input/output inverse theorem and the relaxed multichannel least-squares method is discussed. Two algorithms taking into account the system identification errors are developed. Firstly, an optimally-stopped weighted conjugate gradient algorithm is proposed. A conjugate gradient iterative method is employed to compute the equalization system. The iteration process is stopped optimally with respect to system identification errors. Secondly, a system-identification-error-robust equalization method exploring the use of error models is presented, which incorporates system identification error models in the weighted multichannel least-squares formulation.
Exploring methods to enhance crystallisation of membrane proteins
Creators: name: Yashiro, Shoko
Publisher: name: Imperial College London
Year: 2009

description: This thesis presents three different approaches to enhance crystallization of membrane proteins. The major part of the thesis presents the establishment of a method to stabilize membrane proteins by mutagenesis. Although it is fairly straightforward to introduce mutations in proteins using random mutagenesis, the selection of mutants that are more stable than wild type generally involves exhaustive screening. Adding detergent stability as a selection parameter to the thermal stability, this project established a generic high throughput screening method using an Escherichia coli sodium-proton antiporter NhaA as a model. A screening funnel rapidly eliminated unstable mutants based on their expression level, octyl glucoside solubility, and elution profile of fluorescent size exclusion chromatography (FSEC), leaving only several mutants to be subjected to rigorous thermal stability assay. The screening identified 2 mutants, which exhibited significantly improved thermostability at the protein’s active pH of 8.5. The preliminary crystal structure of an NhaA dimer complex is also presented. This structure was determined at a resolution of 3.8 Å. Although biochemical studies have suggested NhaA exists as a dimer in the lipid bilayer, the only available dimer structure has been a cryo-EM model at 7 Å published earlier this year. Overall the two structures are very similar although the position of the β-sheet at the dimer interface differs slightly. Two minor chapters discuss construct engineering and antibody co-crystallization to enhance crystallization. Constructs were made for five different P450s involved in biosynthesis of the moulting hormone ecdysone from Drosophila melanogaster and Bombyx mori. The null expression under different growth conditions suggests the design requires further optimization. Co-crystallization of human erythrocyte anion exchanger Band 3 with a Fab fragment of BRAC18 resulted in Fab crystals. The Fab crystal structure was determined to a resolution of 1.6 Å with the view of aiding Band 3: Fab structure determination.

description: We consider radial solutions of the slightly subcritical problem $-Δu_\varepsilon = |u_\varepsilon|^{\frac{4}{n-2}-\varepsilon}u_\varepsilon$ either on $\mathbb R^n$ ($n\geq 3$) or in a ball $B$ satisfying Dirichlet or Neumann boundary conditions. In particular, we provide sharp rates and constants describing the asymptotic behavior (as $\varepsilon\to 0$) of all local minima and maxima of $u_\varepsilon$ as well as its derivative at roots. Our proof is done by induction and uses energy estimates, blow-up/normalization techniques, a radial pointwise Pohozaev identity, and some ODE arguments. As corollaries, we complement a known asymptotic approximation of the Dirichlet nodal solution in terms of a tower of bubbles and present a similar formula for the Neumann problem.

description: We consider the topological gauged WZW model in the generalized momentum representation. The chiral field $g$ is interpreted as a counterpart of the electric field $E$ of conventional gauge theories. The gauge dependence of wave functionals $Ψ(g)$ is governed by a new gauge cocycle $ϕ_{GWZW}$. We evaluate this cocycle explicitly using the machinery of Poisson $σ$-models. In this approach the GWZW model is reformulated as a Schwarz type topological theory so that the action does not depend on the world-sheet metric. The equivalence of this new formulation to the original one is proved for genus one and conjectured for an arbitrary genus Riemann surface. As a by-product we discover a new way to explain the appearance of Quantum Groups in the WZW model.

Adaptive Regression Methods with Application to Streaming Financial Data
Creators: name: Tsagaris, Theodoros
Publisher: name: Imperial College London
Year: 2010

description: This thesis is concerned with the analysis of adaptive incremental regression algorithms for data streams. The development of these algorithms is motivated by issues pertaining to financial data streams, data which are very noisy, non-stationary and exhibit high degrees of dependence. These incremental regression techniques are subsequently used to develop efficient and adaptive algorithms for portfolio allocation. We develop a number of temporally incremental regression algorithms that have the following attributes; efficiency: the algorithms are iterative, robustness: the algorithms have a built-in safeguard for outliers and/or use regularisation techniques to alleviate for estimation error, and adaptiveness: the algorithms estimation is adaptive to the underlying streaming data. These algorithms make use of known regression techniques: EWRLS (Exponentially Weighted Recursive Least Squares), TSVD (Truncated Singular Value Decomposition) and FLS (Flexible Least Squares). We focus more of our attention on a proposed robust version of EWRLS algorithm, denoted R-EWRLS, and assess its robustness using a purpose built simulation engine. This simulation engine is able to generate correlated data streams whose drift and correlation change over time and can be subjected to randomly generated outliers whose magnitudes and directions vary. The R-EWRLS algorithm is developed further to allow for a self-tuned forgetting factor in the formulation. The forgetting factor is an important tool to account for non-stationarity in the data through an exponential decay profile which assigns more weight to the more recent data. The new algorithm is assessed against the R-EWRLS algorithm using various performance measures. A number of applications with real data from equities and foreign exchange are used. Various measures are computed to compare our algorithms to established portfolio allocation techniques. The results are promising and in many cases outperform benchmark allocation techniques.

Conserved charges and supersymmetry in principal chiral and WZW models

description: Conserved and commuting charges are investigated in both bosonic and supersymmetric classical chiral models, with and without Wess-Zumino terms. In the bosonic theories, there are conserved currents based on symmetric invariant tensors of the underlying algebra, and the construction of infinitely many commuting charges, with spins equal to the exponents of the algebra modulo its Coxeter number, can be carried out irrespective of the coefficient of the Wess-Zumino term. In the supersymmetric models, a different pattern of conserved quantities emerges, based on antisymmetric invariant tensors. The current algebra is much more complicated than in the bosonic case, and it is analysed in some detail. Two families of commuting charges can be constructed, each with finitely many members whose spins are exactly the exponents of the algebra (with no repetition modulo the Coxeter number). The conserved quantities in the bosonic and supersymmetric theories are only indirectly related, except for the special case of the WZW model and its supersymmetric extension.

A SUPERSPACE FORMULATION FOR THE BATALIN VILKOVISKY FORMALISM WITH EXTENDED BRST INVARIANCE

description: A superspace formulation for the Batalin Vilkovisky formalism (also called field-antifield quantization ) with extended BRST invariance (BRST and anti-BRST invariance ) for gauge theories with closed algebra is presented. In contrast to a recent formulation, where only BRST invariance holds off shell, two collective sets of fields are introduced and an off shell realization of the extended algebra in a superspace with two Grassmann coordinates is obtained. The example of the Yang Mills theory is also considered.

Distinguished self-adjoint extension of the two-body Dirac operator with Coulomb interaction
Creators: name: Deckert, Dirk-André

Subjects: subject: Mathematical Physics (math-ph)

description: We study the two-body Dirac operator in a bounded external field and for a class of unbounded pair-interaction potentials, both repulsive and attractive, including the Coulomb type. Provided the coupling constant of the pair-interaction fulfills a certain bound, we prove existence of a self-adjoint extension of this operator which is uniquely distinguished by means of finite potential energy. In the case of Coulomb interaction, we require as a technical assumption the coupling constant to be bounded by $2/π$.

description: We discuss observables of an equivariant extension of the A-model in the framework of the AKSZ construction. We introduce the A-model observables, a class of observables that are homotopically equivalent to the canonical AKSZ observables but are better behaved in the gauge fixing. We discuss them for two different choices of gauge fixing: the first one is conjectured to compute the correlators of the A-model with target the Marsden-Weinstein reduced space; in the second one we recover the topological Yang-Mills action coupled with A-model so that the A-model observables are closed under supersymmetry.
