Fluid Dynamics in Nanoscale Systems with Amorphous Surfaces and the Interaction of Nanoparticles with Surfactant Layers
Creators: name: Groombridge, Matthew
Publisher: name: Imperial College London
Year: 2012

description: The flow properties of fluids confined within nanoscale pores have been investigated. This study attempts to increase the understanding of some of the factors which affect flow over amorphous surfaces. Direct comparisons are made between experimental data and theoretical systems. Equilibrium and non-equilibrium methods are used to calculate the slip coefficient and a relaxation time, which is related to the interfacial friction. This is shown to be a simple and reliable way of predicting flow behaviour across a wide range of systems with different structures. Other methods, such as those based on Maxwell’s model, are found to be less reliable in systems with very rough surfaces. Enhanced flow rates, as found in some experimental systems, would have enormous benefits in a nanofluidic device. The flow dynamics in a variety of systems with different surface roughnesses and chemical compositions have been determined. The flow of water and decane fluids over a variety of carbon surfaces have been studied. Flow over PDMS surfaces with varying levels of oxidation has also been analysed. Enhancements are found to be lower than those predicted experimentally. There is a wide interest in the effects of inhalation of nanoparticles on lung tissues. In this work, the interactions of several environmentally interesting nanoparticles (fullerenes and titanium dioxide) with a model lung membrane have been simulated. The trajectories and interactions of the nanoparticles with the membranes are studied. Hydrophobic particles are found to sit amongst the lipid tails, hydrophillic particles nearer the water/lipid interface. Although no particles are found to cross freely into the water layer, an interesting effect is noted whereby water molecules are seen to leave the water phase of the membrane and coat the surface of hydrophilic nanoparticles. For the largest nanoparticles this creates a bridge across the membrane from the water phase to the vacuum.

description: Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy formation and evolution, since they present properties that can be found in both elliptical and spiral galaxies. In this work we study the kinematics of the globular cluster (GC) systems of three lenticular galaxies located in low density environments (NGC 2768, NGC 3115 and NGC 7457), and compare them with the kinematics of planetary nebulae (PNe). The PNe and GC data come from the Planetary Nebulae Spectrograph and the SLUGGS Surveys. Through photometric spheroid-disc decomposition and PNe kinematics we find the probability for a given GC to belong to either the spheroid or the disc of its host galaxy or be rejected from the model. We find that there is no correlation between the components that the GCs are likely to belong to and their colours. Particularly, for NGC 2768 we find that its red GCs display rotation preferentially at inner radii (Re<1). In the case of the GC system of NGC 3115 we find a group of GCs with similar kinematics that are not likely to belong to either its spheroid nor disc. For NGC 7457 we find that 70% of its GCs are likely to belong to the disc. Overall, our results suggest that these galaxies assembled into S0s through different evolutionary paths. Mergers seem to have been very important for NGC 2768 and NGC 3115 while NGC 7457 is more likely to have experienced secular evolution.

Holographic entanglement entropy in AdS4/BCFT3 and the Willmore functional

description: We study the holographic entanglement entropy of spatial regions having arbitrary shapes in the AdS4/BCFT3 correspondence with static gravitational backgrounds, focusing on the subleading term with respect to the area law term in its expansion as the UV cutoff vanishes. An analytic expression depending on the unit vector normal to the minimal area surface anchored to the entangling curve is obtained. When the bulk spacetime is a part of AdS4, this formula becomes the Willmore functional with a proper boundary term evaluated on the minimal surface viewed as a submanifold of a three dimensional flat Euclidean space with boundary. For some smooth domains, the analytic expressions of the finite term are reproduced, including the case of a disk disjoint from a boundary which is either flat or circular. When the spatial region contains corners adjacent to the boundary, the subleading term is a logarithmic divergence whose coefficient is determined by a corner function that is known analytically, and this result is also recovered. A numerical approach is employed to construct extremal surfaces anchored to entangling curves with arbitrary shapes. This analysis is used both to check some analytic results and to find numerically the finite term of the holographic entanglement entropy for some ellipses at finite distance from a flat boundary.

MIMO Radar: Target Localisation
Creators: name: Luo, Kai
Publisher: name: Imperial College London
Year: 2013

description: The research presented in this thesis is concerned with multi-target localisation in MIMO radar. In particular, the aim is to develop novel algorithms which can improve the performance of target localisation. Firstly, a general spatiotemporal received signal model for MIMO radar is formulated. When the targets' relative delays are negligible, the general model turns into the spatial only signal model in which, in order to enjoy the enhanced parameter identifiability brought by the waveform diversity, a combined approach based on the virtual array structure is proposed for the multiple targets' directions and path gains estimation. The virtual array structure enables the proposed approach to identify more targets with accurate estimation. Besides, inspired by STAR manifold in communications, a novel spatiotemporal signal model for MIMO radar is proposed, which enables the existing multi-target localisation methods designed for the spatial only model working for the spatiotemporal one. Secondly, the multi-target localisation of MIMO radar operating in an envi- ronment with closely located targets is concerned. In such a scenario, the mu- tual interferences among targets severely degrade the performance of the current multi-target parameter estimators. Thus, an optimisation which takes account of the suppression of the mutual interferences for multi-target parameter estimation is formulated and the solutions to it are derived. Thirdly, based on these solu- tions, two novel multi-target parameter estimators are presented. By suppressing the interferences in the estimation, both the proposed methods outperform the existing ones. Finally, for the purpose of exploiting the high directional gain provided by the Tx beamforming in the multi-target localisation of MIMO radar, a joint Tx and Rx multi-target localisation approach is proposed. The cooperation between the Tx beamforming and target localisation enables the proposed approach to achieve better performance for the localisation of multiple targets.

description: We present the first high-resolution, submillimeter-wavelength polarimetric observations of -- and thus direct observations of the magnetic field morphology within -- the dense gas of the Pillars of Creation in M16. These 850$\,μ$m observations, taken as part of the BISTRO (B-Fields in Star-forming Region Observations) Survey using the POL-2 polarimeter on the SCUBA-2 camera on the James Clerk Maxwell Telescope (JCMT), show that the magnetic field runs along the length of the pillars, perpendicular to, and decoupled from, the field in the surrounding photoionized cloud. Using the Chandrasekhar-Fermi method we estimate a plane-of-sky magnetic field strength of $170-320\,μ$G in the Pillars, consistent with their having been formed through compression of gas with initially weak magnetization. The observed magnetic field strength and morphology suggests that the magnetic field may be slowing the pillars' evolution into cometary globules. We thus hypothesize that the evolution and lifetime of the Pillars may be strongly influenced by the strength of the coupling of their magnetic field to that of their parent photoionized cloud -- i.e. that the Pillars' longevity results from magnetic support

Microbial translocation, immune activation and liver fibrosis in HIV/hepatitis C coinfection
Creators: name: Page, Emma
Publisher: name: Imperial College London
Year: 2012

description: Reasons for the accelerated progression of liver fibrosis in HIV-1/HCV coinfection are not well defined. Increased microbial translocation and/or immune activation may play a role. The aim of this research was to investigate the relationship between Th17 and Th22 cells with microbial translocation, immune activation and liver fibrosis in HIV-1/HCV coinfection. HIV-1 infection led to a preferential reduction in peripheral Th17 and Th22 cells and a reduction in Th17:Treg and Th22:Treg cell ratios. There was a negative correlation between Th17 and Th22 frequencies, Th17:Treg and Th22:Treg ratios with markers of microbial translocation and immune activation. In addition we found significant increases in the activity of the enzyme IDO, which promotes CD4 Treg development at the expense of Th17 cells. Alterations in the distribution of Th17, Th22 and Treg cells may be a mechanism through which immune activation promotes fibrogenesis. HIV-1/HCV coinfection led to increased immune activation and microbial translocation. There was a more marked depletion of Th17 cells than in HIV-1 monoinfection, and reduced Th22 cells, Th17:Treg ratio and Th22:Treg ratio, which were not seen in HCV monoinfection. Unlike HCV monoinfection there was no increase in Th1 cells in HIV-1/HCV coinfection. There was a stronger association between reduction in Th17:Treg, Th22:Treg ratios and markers of immune activation and microbial translocation in patients with HIV-1/HCV coinfection compared to HCV monoinfection. Th1 cells displayed robust negative correlations with immune activation in HIV-1/HCV coinfection, but not in HCV monoinfection. There was no association between alterations in CD4 T cell subsets and liver fibrosis in HCV monoinfection. In HIV-1/HCV coinfection reduced Th17 cell and depleted Th1 responses were associated with liver fibrosis. Our research implicates HIV-1 driven depletion of Th1 and Th17 cells in the development of liver fibrosis in HIV-1/HCV co-infection.

description: Chondrites are one of the most primitive objects in the solar system, and keep the record of the degree of thermal metamorphism experienced in their parent bodies. This thermal history can be classified by the petrologic type. We investigate the thermal evolution of planetesimals to account for the current abundances (known as the fall statistics) of petrologic types 3 - 6 ordinary chondrites. We carry out a number of numerical calculations in which formation times and sizes of planetesimals are taken as parameters. We find that planetesimals that form within 2.0 Myr after the formation of Ca-Al-rich inclusions (CAIs) can contain all petrologic types of ordinary chondrites. Our results also indicate that plausible scenarios of planetesimal formation, which are consistent with the fall statistics, are that planetesimals with radii larger than 60 km start to form around 2.0 Myr after CAIs and/or that ones with radii less than 50 km should be formed within 1.5 Myr after CAIs. Thus, thermal modelling of planetesimals is important for revealing the occurrence and amount of metamorphosed chondrites, and for providing invaluable insights into planetesimal formation.

Phase transition in scalar $ϕ^4$-theory beyond the super daisy resummations

description: The temperature phase transition in scalar $ϕ^4(x)$ field theory with spontaneous symmetry breaking is investigated in a partly resummed perturbative approach. The second Legendre transform is used and the resulting gap equation is considered in the extrema of the free energy functional. It is found that the phase transition is of first order in the super daisy as well as in a certain beyond super daisy resummations. No unwanted imaginary parts in the free energy are found but a loss of the smallness of the effective expansion parameter near the phase transition temperature is found in both cases. This means an insufficiency of the resummations or a deficit of the perturbative approach.

A Mechanism for Decentralized Participation of Flexible Demand in Electricity Markets
Creators: name: Papadaskalopoulos, Dimitrios
Publisher: name: Imperial College London
Year: 2013

description: In deregulated power systems, the realization of the significant demand flexibility potential should be coupled with its integration in electricity markets. The approaches examined in the available literature to achieve this paradigm change exhibit significant limitations. Centralized mechanisms raise communication and computational scalability issues as well as privacy concerns by the consumers, while dynamic pricing schemes neglect the natural interdependence between demand and prices and thus fail to realize the actual value of demand flexibility. This thesis proposes, analyzes and tests a novel pool market clearing mechanism enabling flexible demand participation in electricity markets by combining the solution optimality of centralized mechanisms with the decentralized demand participation structure of dynamic pricing schemes, and based on Lagrangian Relaxation (LR) principles. The price-response optimization problems corresponding to three flexible demand technologies with significant potential -namely electric vehicles with flexible charging capability, space-heating electric heat pumps accompanied by heat storage and wet appliances with deferrable initiation time- are mathematically formulated, incorporating detailed models of their operational properties. Non-convexities of these price-response problems and their impacts on the ability of the basic LR structure to reach feasible market solutions are identified and analyzed. An effective LR heuristic method is developed to produce both feasible and high-quality solutions, by applying a suitable relative flexibility restriction on flexible demand, in order to avoid its concentration to the same low-priced time periods, without requiring knowledge of the individual flexible loads’ characteristics. For flexible electric vehicles and electric heat pumps this restriction is associated with their maximum power demand, while for flexible wet appliances it is associated with their maximum initiation time deferrability. In the case where network constraints are included in the problem, location-specific values for this flexibility restriction are determined in order to improve the quality of the obtained solution, through an algorithm involving approximate characterization of the nodal aggregated flexible demand populations based on their price responses, in order to avoid extensive computational requirements. Finally, suitable Lagrangian multipliers update algorithms are examined in order to reduce the number of iterations and thus the communication requirements of the proposed mechanism. Extensive case studies on a model of the UK power system, with different penetration and flexibility scenarios for the three examined technologies, validate the theoretical properties of the proposed mechanism and analyze the impact of flexible demand’s market participation.

Computationally Unifying Urban Masterplanning
Creators: name: Birch, David Alan
Publisher: name: Imperial College London
Year: 2013

description: Urban masterplanning is the process of creating a coherent design for developing a campus, suburb, city or region. Unfortunately these design and analysis teams face challenges which prevent rapid quantitative analysis of design iterations; precluding potential design improvement. These include limited automation, poor integration of modelling disciplines and, in particular, very limited scope for design space exploration. This thesis investigates these challenges and their solutions. A computational frame- work HierSynth is presented to help computationally unify the design and analysis sides of the urban masterplanning community. The key contribution of this thesis is HierSynths data model. This presents a reconceptualization of the workflow graph by composing it with tree based design-decompositions commonly found in architectural interoperability formats. This is achieved through a hierarchy of design queries, templates and analyses which when executed form a design hierarchy annotated with evaluated analyses. This enables detailed multi-scale analysis directly on design elements whilst supporting scenario generation and design space exploration capabilities and techniques to explore design improvements. The HierSynth framework is evaluated by application to a major commercial masterplanning project with Arup North America and is used to explore the most effective techniques for generating design insight. HierSynth enabled an order-of-magnitude more analysis iterations and previously infeasible design space exploration to answer design questions. During this collaboration an unexpected challenge was identified in maintaining and debugging complex, highly interrelated analysis models implemented as spreadsheets. A toolkit to address this is developed and applied to several generations of complex multi-disciplinary sustainability models. In summary this thesis presents evidence of the need for, implementation of, and practical benefits from, computationally unifying urban masterplanning design and analysis. The key contribution is a compositional data model supporting this unification. Finally avenues for further work are explored to further aid this community including data provenance and supporting smart cities.

description: Transition metal dichalcogenides (TMDs), whether in bulk or in monolayer form, exhibit a rich variety of charge-density-wave (CDW) phases and stronger periodic lattice distortions. While the actual role of nesting has been under debate, it is well understood that the microscopic interaction responsible for the CDWs is the electron-phonon coupling. The case of TiSe$_2$ is however unique in this family in that the normal state above the critical temperature $T_\mathrm{CDW}$ is characterized by a small quasiparticle bandgap as measured by ARPES, so that no nesting-derived enhancement of the susceptibility is present. It has therefore been argued that the mechanism responsible for this CDW should be different and that this material realizes the excitonic insulator phase proposed by Walter Kohn. On the other hand, it has also been suggested that the whole phase diagram can be explained by a sufficiently strong electron-phonon coupling. In this work, in order to estimate how close this material is to the pure excitonic insulator instability, we quantify the strength of electron-hole interactions by computing the exciton band structure at the level of hybrid density functional theory, focusing on the monolayer. We find that in a certain range of parameters the indirect gap at $q_{\mathrm{CDW}}$ is significantly reduced by excitonic effects. We discuss the consequences of those results regarding the debate on the physical mechanism responsible for this CDW. Based on the dependence of the calculated exciton binding energies as a function of the mixing parameter of hybrid DFT, we conjecture that a necessary condition for a pure excitonic insulator is that its noninteracting electronic structure is metallic.

description: We introduce a calculus of the Lie algebra valued functions present in Tseytlin's proposal for the nonabelian DBI action, and apply it to show that the recently found dyonic instanton is a solution of the full nonabelian DBI action. The geometry of this solution exhibits a new effect of ``blowing-up'' of the brane, which was not present in the case of the brane realisation of monopoles. We interpret this solution as the superposition of the D0 brane and fundamental string F1 which connects two separated D4 branes. Both F1 and D0 are delocalised in the ``blown-up'' region between two separated D4 branes.

Inferring useful static types for duck typed languages
Creators: name: Lamaison, Alexander
Publisher: name: Imperial College London
Year: 2012

description: Complete and precise identification of types is essential to the effectiveness of programming aids such as refactoring or code completion. Existing approaches that target dynamically typed languages infer types using flow analysis, but flow analysis does not cope well with heavily used features such as heterogeneous containers and implicit interfaces. Our solution makes the assumption that programs that are known to work do not encounter run-time type errors which allows us to derive extra type information from the way values are used, rather than simply where those values originate. This is in keeping with the “duck typing” philosophy of many dynamically typed languages. The information we derive must be conservative, so we describe and formalise a technique to ‘freeze’ the duck type of a variable using the features, such as named methods, that are provably present on any run of the program. Development environments can use these sets of features to provide code-completion suggestions and API documentation, amongst other things. We show that these sets of features can be used to refine imprecise flow analysis results by using the frozen duck type to perform a structural type-cast. We first formalise this for an idealised duck-typed language semantics and then show to what extent the technique would work for a real-world language, Python. We demonstrate its effectiveness by performing an analysis of several real-world Python programs which shows that we can infer the types of method-call receivers more precisely than can flow analysis alone.

Modelling of multiphase flows on adaptive unstructured meshes with applications to the dynamics of volcanic ash plumes
Creators: name: Jacobs, Christian Thomas
Publisher: name: Imperial College London
Year: 2013

description: This thesis describes the development of two numerical models for the study of (1) incompressible multiphase flow and (2) compressible multiphase flow. Both models employ a state-of-the-art adaptive unstructured mesh-based approach which allows the mesh, upon which the model equations are discretised, to be optimised in order to focus numerical resolution in areas important to the dynamics and decrease it where it is not needed as a simulation progresses. The implementation of the models takes place within a computational fluid dynamics code called Fluidity. The application of the models concerns the multi-scale simulation of volcanic ash transport in aqueous solutions and in the atmosphere. Simulations of ash settling in a water tank, which mimic published laboratory experiments, are performed primarily in two dimensions. The results demonstrate that ash particles can either settle slowly and individually, or rapidly and collectively as an ash-laden cloud, referred to as a plume. Two quantities used to measure the tendency for plumes to form are then evaluated with a parameter study. Particles settling collectively are slowed by inertial drag, rather than viscous drag, and it is shown that such quantities must account for this. An improvement to the measures is proposed, along with an alternative measure which uses a more accurate expression for the collective settling timescale. Finally, a two-dimensional kilometre-scale volcanic eruption of hot gas and ash into the atmosphere is simulated. The results are compared with those from MFIX, a leading multiphase flow code. Both Fluidity and MFIX are able to successfully capture the key characteristics of an eruption event. The benefits of the adaptive unstructured mesh-based approach are highlighted throughout the thesis by demonstrating that it maintains solution accuracy whilst providing a substantial reduction in computational requirements when compared to the same simulation performed using a fixed mesh of uniform resolution.
Motion of a rigid body in a tidal field: an application to elliptical galaxies in clusters

Year: 1998

description: We investigate the motion, near the equilibrium configurations, of an initially spinless rigid body subject to an external tidal field. Two cases are considered: when the center of mass of the body is at rest at the equilibrium point of the field generated by a generic mass distribution, and when it is placed on a circular orbit subject to a spherically symmetric potential. A complete analysis of the equilibrium configurations is carried out for both cases. First, we derive the conditions for the stable equilibria, and then we analyze the frequencies of oscillations around the equilibrium positions. In view of these results, we consider the problem of alignment of galaxies in clusters. After estimating the period of the oscillations induced on the galaxies by the tidal field of the cluster, we discuss the possible effect of resonances between stellar orbits inside the galaxy and the oscillations of the galaxy as a whole; this may be a mechanism responsible for producing an intracluster stellar population.

Strategy-based dynamic assignment in transit networks with passenger queues
Creators: name: Trozzi, Valentina
Publisher: name: Imperial College London
Year: 2013

description: This thesis develops a mathematical framework to solve the problem of dynamic assignment in densely connected public transport (or transit – the two words are interchangeably used) networks where users do not time their arrival at a stop with the lines’ timetable (if any is published). In the literature there is a fairly broad agreement that, in such transport systems, passengers would not select the single best itinerary available, but would choose a travel strategy, namely a bundle of partially overlapping itineraries diverging at stops along different lines. Then, they would follow a specific path depending on what line arrives first at the stop. From a graph-theory point of view, this route-choice behaviour is modelled as the search for the shortest hyperpath (namely an acyclic sub-graph which includes partially overlapping single paths) to the destination in the hypergraph that describes the transit network. In this thesis, the hyperpath paradigm is extended to model route choice in a dynamic context, where users might be prevented from boarding the lines of their choice because of capacity constraints. More specifically, if the supplied capacity is insufficient to accommodate the travel demand, it is assumed that passenger congestion leads to the formation of passenger First In, First Out (FIFO) queues at stops and that, in the context of commuting trips, passengers have a good estimate of the expected number of vehicle passages of the same line that they must let go before being able to board. By embedding the proposed demand model in a fully dynamic assignment model for transit networks, this thesis also fills in the gap currently existing in the realm of strategy-based transit assignment, where – so far – models that employ the FIFO queuing mechanism have proved to be very complex, and a theoretical framework for reproducing the dynamic build-up and dissipation of queues is still missing.

description: We study the generalization of noncommutative gauge theories to the case of orthogonal and symplectic groups. We find out that this is possible, since we are allowed to define orthogonal and symplectic subgroups of noncommutative unitary gauge transformations even though the gauge potentials and gauge transformations are not valued in the orthogonal and symplectic subalgebras of the Lie algebra of antihermitean matrices. Our construction relies on an antiautomorphism of the basic noncommutative algebra of functions which generalizes the charge conjugation operator of ordinary field theory. We show that the corresponding noncommutative picture from low energy string theory is obtained via orientifold projection in the presence of a non-trivial NSNS B-field.

Clonality in adult T-cell leukaemia/lymphoma
Creators: name: Cook, Lucy
Publisher: name: Imperial College London

description: Human T-lymphotropic virus type 1 (HTLV-1) is a retrovirus that persists lifelong within the infected host by driving expansion of infected CD4+T-cells. It is the cause of adult T-cell leukaemia/lymphoma (ATL), an aggressive CD4+ T-cell malignancy, which arises in approximately 5% of individuals typically following decades of asymptomatic infection. The reasons why some individuals develop ATL remain unknown. In this laboratory a novel customised high throughput sequencing and bioinformatic method has been developed in order to map and accurately quantify the proviral integration sites within each host genome in order to identify clonal populations within each host. In this study I aimed first to test the hypothesis that there is a single provirus integrated into each host genome, and secondly to test the hypothesis that the site of retroviral integration determines the risk of leukaemia. In order to quantify the average number of proviral integration sites in each host cell, we isolated infected T-cells from the peripheral blood of infected individuals by limiting dilution cloning. Integration site analysis of these clones revealed that in natural infection each T-cell clone carries a single integrated provirus. This work formed the basis of a publication in the journal Blood (Cook et al 2012). I describe the systematic analysis of the clonality, structure and the integrity of the proviral tax gene in a large cohort of ATL patients (n=197). I correlate these findings with the clinical subtype of ATL and the landscape of the host genome flanking the proviral integration site. Based upon our findings we conclude that the integration site in cis does not directly cause leukaemogenesis and hypothesise that the absolute number of infected clones within an individual, and not oligoclonal proliferation, predisposes to malignant transformation.

description: The low participation of Pacific students in tertiary STEM studies has implications for schools as they consider how best to engage these learners in STEM subjects (Science, Technology, Engineering and Mathematics). This article reports on an innovative project that supports Pacific learners with STEM learning through 3D printing technology. Creative STEM Pathways is a university-led initiative which has successfully brought 3D technology to the classroom, providing culturally-sustaining, hands-on and relevant learning opportunities. We used an Appreciative Inquiry lens to help us explore how the programme could create positive learning experiences. In this article, we share experiences of its development and delivery. We highlight successes and challenges, offering practical insight to those considering similar innovation in the classroom.
