description: We consider a heteroclinic network in the framework of winnerless competition of species. It consists of two levels of heteroclinic cycles. On the lower level, the heteroclinic cycle connects three saddles, each representing the survival of a single species; on the higher level, the cycle connects three such heteroclinic cycles, in which nine species are involved. We show how to tune the predation rates in order to generate the long time scales on the higher level from the shorter time scales on the lower level. Moreover, when we tune a single bifurcation parameter, first the motion along the lower and next along the higher-level heteroclinic cycles are replaced by a heteroclinic cycle between 3-species coexistence-fixed points and by a 9-species coexistence-fixed point, respectively. We also observe a similar impact of additive noise. Beyond its usual role of preventing the slowing-down of heteroclinic trajectories at small noise level, its increasing strength can replace the lower-level heteroclinic cycle by 3-species coexistence fixed-points, connected by an effective limit cycle, and for even stronger noise the trajectories converge to the 9-species coexistence-fixed point. The model has applications to systems in which slow oscillations modulate fast oscillations with sudden transitions between the temporary winners.

description: The propagation of a dissipative solitary wave across an interface is studied in a binary complex plasma. The experiments were performed under microgravity conditions in the PK-3 Plus Laboratory on board the International Space Station using microparticles with diameters of 1.55 micrometre and 2.55 micrometre immersed in a low-temperature plasma. The solitary wave was excited at the edge of a particle-free region and propagated from the sub-cloud of small particles into that of big particles. The interfacial effect was observed by measuring the deceleration of particles in the wave crest. The results are compared with a Langevin dynamics simulation, where the waves were excited by a gentle push on the edge of the sub-cloud of small particles. Reflection of the wave at the interface is induced by increasing the strength of the push. By tuning the ion drag force exerted on big particles in the simulation, the effective width of the interface is adjusted. We show that the strength of reflection increases with narrower interfaces.
The automation of PDE-constrained optimisation and its applications
Creators: name: Funke, Simon
Publisher: name: Imperial College London
Year: 2012

description: This thesis is concerned with the automation of solving optimisation problems constrained by partial differential equations (PDEs). Gradient-based optimisation algorithms are the key to solve optimisation problems of practical interest. The required derivatives can be efficiently computed with the adjoint approach. However, current methods for the development of adjoint models often require a significant amount of effort and expertise, in particular for non-linear time-dependent problems. This work presents a new high-level reinterpretation of algorithmic differentiation to develop adjoint models. This reinterpretation considers the discrete system as a sequence of equation solves. Applying this approach to a general finite-element framework results in an automatic and robust way of deriving and solving adjoint models. This drastically reduces the development effort compared to traditional methods. Based on this result, a new framework for rapidly defining and solving optimisation problems constrained by PDEs is developed. The user specifies the discrete optimisation problem in a compact high-level language that resembles the mathematical structure of the underlying system. All remaining steps, including parameter updates, PDE solves and derivative computations, are performed without user intervention. The framework can be applied to a wide range of governing PDEs, and interfaces to various gradient-free and gradient-based optimisation algorithms. The capabilities of this framework are demonstrated through the application to two PDE-constrained optimisation problems. The first is concerned with the optimal layout of turbines in tidal stream farms; this optimisation problem is one of the main challenges facing the marine renewable energy industry. The second application applies data assimilation to reconstruct the profile of tsunami waves based on inundation observations. This provides the first step towards the general reconstruction of tsunami signals from satellite information.

description: We study the scalar-tensor-tensor non-Gaussian signal in an inflationary model comprising also an axion coupled with SU(2) gauge fields. In this set-up, metric fluctuations are sourced by the gauge fields already at the linear level providing an enhanced chiral gravitational waves spectrum. The same mechanism is at work in generating an amplitude for the three-point function that is parametrically larger than in standard single-field inflation.

Diacritization as a machine translation problem and as a sequence labeling problem

Publisher: name: Association for Machine Translation in the Americas (AMTA)
Year: 2008

description: In this paper we describe and compare two techniques for the automatic diacritization of Arabic text: First, we treat diacritization as a monotone machine translation problem, proposing and evaluating several translation and language models, including word and character-based models separately and combined as well as a model which uses statistical machine translation (SMT) to post-edit a rule-based diacritization system. Then we explore a more traditional view of diacritization as a sequence labeling problem, and propose a solution using conditional random fields (Lafferty et al., 2001). All these techniques are compared through word error rate and diacritization error rate both in terms of full diacritization and ignoring vowel endings. The empirical experiments showed that the machine translation approaches perform better than the sequence labeling approaches concerning the error rates.
Mechanisms of NOD1-induced inflammation in vascular tissue
Creators: name: Gatheral, Timothy
Publisher: name: Imperial College London
Year: 2012

description: Blood vessels play a vital role in human disease including pathogen driven conditions such as septic shock and acute lung injury. In the innate immune system, host pattern recognition receptors (PRRs) recognise preserved pathogen associated molecular patterns (PAMPs) leading to cell activation. Previous work has shown that blood vessels respond to Gram negative bacteria via the PRRs Toll like receptor 4 (TLR4) and nucleotide oligomerisation domain 1 (NOD1). Indeed stimulation with a specific NOD1 agonist can induce vascular shock in rats (Cartwright, Murch et al. 2007). In humans however, the role of NOD1 in blood vessels is relatively unexplored. Accordingly, in this thesis I have sought to characterise the activity of NOD1 in rodent and human vascular tissue with comparison to TLR4 responses. I have shown that in rodents NOD1 is predominantly expressed and active in vascular cells and whole vessels. Crucially vessel organ culture suggests a predominant role for the endothelium in early responses to NOD1 and TLR4 agonists. I have then gone on to demonstrate induction of key inflammatory mediators by NOD1 agonists in human vessels and vascular cells, confirming the importance of the endothelium in this system. Finally I have used pharmacological tools to describe the signalling pathways downstream of NOD1 and TLR4 in endothelial cells including use of highly novel NOD1 pathway inhibitors. In conclusion, NOD1 is identified as an important PRR mediating inflammatory responses in rodent and human vascular tissue. The endothelium emerges as a key site for NOD1 mediated inflammation whilst the use of highly novel signalling inhibitors has enabled clear differentiation of NOD1 and TLR4 signalling. This suggests the possibility of selective targeting of NOD1 in human disease where disorders of the vasculature predominate.

description: Microlensing events towards the Large Magellanic Cloud entail that a sizable fraction of dark matter is in the form of MACHOs (Massive Astrophysical Compact Halo Objects), presumably located in the halo of the Galaxy. Within the present uncertainties, brown dwarfs are a viable candidate for MACHOs. Various reasons strongly suggest that a large amount of MACHOs should actually consist of binary brown dwarfs. Yet, this circumstance looks in flat contradiction with the fact that MACHOs have been detected as unresolved objects so far. We show that such an apparent paradox does not exist within a model in which MACHOs are clumped into dark clusters along with cold molecular clouds, since dynamical friction on these clouds makes binary brown dwarfs very close. Moreover, we argue that future microlensing experiments with a more accurate photometric observation can resolve binary brown dwarfs.

Advancement of MSA-technique for stiffness modeling of serial and parallel robotic manipulators

description: The paper presents advancement of the matrix structural analysis technique (MSA) for stiffness modeling of robotic manipulators. In contrast to the classical MSA, it can be applied to both parallel and serial manipulators composed of flexible and rigid links connected by rigid, passive or elastic joints with multiple external loadings. The manipulator stiffness model is presented as a set of basic equations describing the link elasticities that are supplemented by a set of constraints describing connections between links. These equations are aggregated straightforwardly in a common linear system without traditional merging of the matrix rows and columns, which allows avoiding conventional manual transformations at the expense of numerical inversion of the sparse matrix of higher dimension.

description: We deal with quantum field theory in the restriction to external Bose fields. Let $(iγ^μ\partial_μ- \mathcal{B})ψ=0$ be the Dirac equation. We prove that a non-quantized Bose field $\mathcal{B}$ is a functional of the Dirac field $ψ$, whenever this $ψ$ is strictly canonical. Performing the trivial verification for the $\mathcal{B} := m = $ constant which yields the free Dirac field, we also prepare the tedious verifications for all $\mathcal{B}$ which are non-quantized and static. Such verifications must not be confused, however, with the easy and rigorous proof of our formula, which is shown in detail.

A curve is said to be a rectifying curve if, in all points of the curve, the orthogonal complement of its normal vector contains a fixed point. We characterize rectifying curves in the $n$-dimensional Euclidean space in different ways: using conditions on their curvatures, using an expression for the tangential component, the normal component or the binormal components of their position vector, and by constructing them starting from an arclength parameterized curve on the unit hypersphere.

A quantum mechanics of the neutral Weyl particle in even--dimensional space--time is suggested and the connection of this theory with the theory of Mayorana--Weyl particle in QFT is discussed for D=10.

description: We have studied using the KLUN sample of 5171 spiral galaxies having Tully-Fisher distance moduli, the average radial space distribution of galaxies out to a distance of about 200 Mpc (for H_0=50 km/s/Mpc). One motivation came from the current debate on the fractal dimension D and maximum scale of fractality. To study this question, we used a new method based on photometric TF distances, independent of redshift, to construct the number density distribution. Our main results are: (1) While scattered below about 20 Mpc, at larger distances the radial distribution starts to follow, in terms of distance modulus mu_TF, the law log N = 0.46 mu + const., using diameter TF relation, and log N = 0.40 mu + const. for magnitudes. These are the predictions based on fractal dimensions 2.3 and 2.0, respectively. These radial density gradients are valid up to the limits of KLUN, or about 200 Mpc. (2) We have tried to understand the derived radial density behaviour as a result of some bias in KLUN or our analysis, however, without success. Numerical simulations have shown that the method itself works. If the density law is caused by incompleteness in the diameter limited KLUN sample, then the incompleteness should start at widely different angular diameters d_25 for different values of rotation parameter log V_M, which would be quite unexpected. (3) If correlation studies favoring long scale fractality (200 Mpc or more) and D ~ 2 are correct, the position of our Galaxy would be close to average in the Universe, with the galaxy density decreasing around us according to the expected law.

description: The analytic expressions for the maximum and minimum reflectance of optical films coated with gapped graphene are derived in the application region of the Dirac model with account of multiple reflections. The respective film thicknesses are also found. In so doing the film material is described by the frequency-dependent index of refraction and graphene by the polarization tensor defined along the real frequency axis. The developed formalism is illustrated by an example of the graphene-coated film made of amorphous silica. Numerical computations of the maximum and minimum reflectances and respective film thicknesses are performed at room temperature in two frequency regions belonging to the near-infrared and far-infrared domains. It is shown that in the far-infrared domain the graphene coating makes a profound effect on the values of maximum reflectance and respective film thickness leading to a relative increase of their values by up to 65% and 50%, respectively. The maximum transmittance of a graphene-coated film of appropriately chosen thickness is shown to exceed 90%. Possible applications of the obtained results are discussed.

description: When a swollen, thermoresponsive polymer gel is heated in a solvent bath, it expels solvent and deswells. When this heating is slow, deswelling proceeds homogeneously, as observed in a toroid-shaped gel that changes volume whilst maintaining its toroidal shape. By contrast, if the gel is heated quickly, an impermeable layer of collapsed polymer forms and traps solvent within the gel, arresting the volume change. The ensuing evolution of the gel then happens at fixed volume, leading to phase-separation and the development of inhomogeneous stress that deforms the toroidal shape. We observe that this stress can cause the torus to buckle out of the plane, via a mechanism analogous to the bending of bimetallic strips upon heating. Our results demonstrate that thermodynamic instabilities, i.e., phase transitions, can be used to actuate mechanical deformation in an extreme thermodynamics of materials.

Heat Transport in Fluids and Interfaces via Non-Equilibrium Molecular Dynamics Simulations
Creators: name: Muscatello, Jordan
Publisher: name: Imperial College London
Year: 2013

description: In this thesis non-equilibrium molecular dynamics is used to investigate effects relating to thermal transport in fluids and interfacial systems. Non-equilibrium molecular dynamics (NEMD) simulations of liquid water were undertaken using the Modified Central Force model (MCFM) of water. Non-equilibrium thermodynamics predicts dipolar alignment as a response to an applied temperature gradient. This effect was systematically investigated by applying thermal gradients of up to 4 K/ Å to a system of MCFM water. This yielded induced electric fields of up to ~ 109 Vm-1. The predictions of non-equilibrium thermodynamics were supported by the simulations. The mechanism of thermal transport was investigated. The effect of electrostatic interactions on the thermal transport properties was also investigated in this model comparing the Ewald summation and Wolf methods. It was found that whilst the change in equation of state using each method is small, the truncation of the electrostatic interactions leads to a lower heat flux density and values for the thermal conductivity that are ~ 5 - 10% lower. The relaxation of the system to a steady-state temperature gradient was also investigated and the timescales involved were found to agree with the results using the macroscopic heat equation. The hydrogen bonding contribution to the heat flux vector was investigated. This was found to contribute to around 30-40% of the total heat flux for MCFM water. The potential energy contribution was found to become negative towards lower temperatures. Also investigated was the thermal conductivity of glassy water with the aim of identifying a difference in the thermal conductivity from liquid to the glass state. The SPC/E model was employed for this purpose but no significant change was identified. NEMD simulations were employed to investigate the interfacial thermal resistance of liquid/vapour and solid/vapour interfaces in a Lennard-Jones system. For energy fluxes of ≈107 Wm-2 a significant interfacial thermal resistance was observed, particularly at low temperatures. To investigate the microscopic origin of the interfacial thermal resistance, the intrinsic sampling method was employed in the liquid/vapour interface. The temperature drop was found to occur in front of the interface in a region where adsorbed atoms at the surface correspond to a density peak in the vapour phase.

description: We point out that averages of equivariant observables of 2D topological gravity are not globally defined forms on moduli space, when one uses the functional measure corresponding to the formulation of the theory as a 2D superconformal model. This is shown to be a consequence of the existence of the Gribov horizon {\it and} of the dependence of the observables on derivatives of the super-ghost field. By requiring the absence of global BRS anomalies, it is nevertheless possible to associate global forms to correlators of observables by resorting to the Čech-De Rham notion of form cohomology. To this end, we derive and solve the ``descent'' of local Ward identities which characterize the functional measure. We obtain in this way an explicit expression for the Čech-De Rham cocycles corresponding to arbitrary correlators of observables. This provides the way to compute and understand contact terms in string theory from first principles.

A Quadratic Gaussian Year-on-Year Inflation Model
Creators: name: Gretarsson, Hringur
Publisher: name: Imperial College London
Year: 2013

description: We introduce a new approach to model the market smile for inflation-linked derivatives by defining the Quadratic Gaussian Year-on-Year inflation model—the QGY model. We directly define the model in terms of a year-on-year ratio of the inflation index on a discrete tenor structure, which, along with the nominal discount bond, is driven by a log-quadratic function of a multi-factor Gaussian Markov process. We find closed-form expressions for the drift of the inflation index and for inflation-linked swaps. We get a Black-Scholes-type pricing formula for year-on-year inflation caplets in semi-analytical form. The formula contains an integral of a multivariate Gaussian density over a quadratic domain. In a two-dimensional case, we show how this integral reduces to a one-dimensional integration along the boundary of a conic section. In the case where the year-on-year inflation ratio is driven by two factors, we specify a spherical parameterisation. This gives an intuitive control over the curvature and the skew of the year-on-year inflation smile and shows the maximum curvature and skew obtainable with a particular three-factor version of the QGY model. Within this three-factor model, we identify a parameterisation to control the autocorrelation structure of the inflation index. We calibrate the model to year-on-year inflation options on the UK’s Retail Prices Index (RPI) and the eurozone’s Harmonised Index of Consumer Prices Excluding Tobacco (HICPxT) and get a good fit to the smile of implied volatilities. We use the calibrated model to price HICPxT zero-coupon inflation options and RPI limited price indices (LPIs). Furthermore, we provide methods to interpolate the process for the inflation index and the year-on-year inflation ratio between dates on the tenor structure. Keywords: Year-on-year inflation modelling; multi-factor log-quadratic Gaussian model; stochastic-volatility parameterisation; inflation autocorrelation; year-on-year inflation calibration; LPI pricing.

description: Aim: To evaluate the burden of uncontrolled gout by examining estimated costs and cost drivers. Materials and methods: Data from the 2012 and 2013 US National Health and Wellness Survey (NHWS; 2012 NHWS, n = 71,157 and 2013 NHWS, n = 75,000) were utilized in this study. Based on self-reported gout diagnosis and gout symptoms, respondents were categorized into three groups: controlled gout (n = 344), uncontrolled gout (n = 2,215), and non-gout controls (n = 126,360). Chi-square tests and one-way analysis of variance (ANOVAs) were used to assess group differences on work productivity loss, healthcare resource utilization, and costs. Zero-inflated negative binomial regressions were used to assess the burden of uncontrolled gout on total costs after controlling for covariates. Results: Patients with uncontrolled gout had higher presenteeism, overall work impairment, activity impairment, and number of emergency department visits than those with controlled gout or controls. Overall, uncontrolled gout patients had both higher indirect and total costs compared to patients with controlled gout. After controlling for confounders, those with uncontrolled gout had higher total costs than controlled gout respondents and non-gout controls; there was no significant difference in total costs between patients with controlled gout and non-gout controls. Limitations: Results were based on cross-sectional, self-reported data, making causal inferences more uncertain. Additionally, sample size was small for controlled-gout respondents. Lastly, sampling weights were not used, thus potentially limiting generalizability. Conclusion: Gout can be an expensive condition, particularly if it is not properly controlled. This study provides support that controlling symptoms (e.g. flares) can reduce the economic and societal burden of gout. Therefore, more attention needs to be paid to effective management of gout symptoms.

As recycling processes are maturing, it is vital to introduce the recyclates in non-safety-critical structural applications. This work aimed at studying the mechanical response of recycled composites and developing analytical models for predicting their failure, and also that of their virgin precursors. The effect of recycling on the mechanical response of composites was assessed by comparing virgin and recycled materials with identical woven architectures. The performance depended on the reclamation cycle and loading mode; under optimal recycling conditions, above 75% of strength and virtually 100% of stiffness were recovered. An experimental study of three state-of-the-art recycled composites revealed complex microstructures, featuring fibres and bundles (held together by residual matrix) of different sizes; this microstructure was key for the fracture process, as bundles significantly toughened the materials. The unique multiscale architecture and mechanical behaviour, while making these recyclates suitable for structural applications, created a need for the development of specific mechanical models for design. In order to predict the intrinsic properties of composites with such multiscale reinforcement, original models for size effects on the tensile strength and fracture toughness of composite bundles were developed. These models combine statistics, micromechanics and self-similar processes; while their development was originally motivated by recycled composites, they are equally relevant for unidirectional virgin composites. Subsequently, a micromechanical model for the fracture toughness of recycled composites was developed; this accounts for fracture, debonding and pull-out of reinforcing units with different sizes and orientations, and was successfully validated against the wide range of toughnesses experimentally measured in the recyclates. This work shows that recycled composites offer an environmentally-friendly and performance-competitive alternative to current structural materials. The models developed can support the optimisation of recycling processes towards damage tolerant materials, as well as their application for eco-design of non-safety-critical structures.

description: We have previously shown how to socially integrate a fish robot into a group of zebrafish thanks to biomimetic behavioural models. The models have to be calibrated on experimental data to present correct behavioural features. This calibration is essential to enhance the social integration of the robot into the group. When calibrated, the behavioural model of fish behaviour is implemented to drive a robot with closed-loop control of social interactions into a group of zebrafish. This approach can be useful to form mixed-groups, and study animal individual and collective behaviour by using biomimetic autonomous robots capable of responding to the animals in long-standing experiments. Here, we show a methodology for continuous real-time calibration and refinement of multi-level behavioural model. The real-time calibration, by an evolutionary algorithm, is based on simulation of the model to correspond to the observed fish behaviour in real-time. The calibrated model is updated on the robot and tested during the experiments. This method allows to cope with changes of dynamics in fish behaviour. Moreover, each fish presents individual behavioural differences. Thus, each trial is done with naive fish groups that display behavioural variability. This real-time calibration methodology can optimise the robot behaviours during the experiments. Our implementation of this methodology runs on three different computers that perform individual tracking, data-analysis, multi-objective evolutionary algorithms, simulation of the fish robot and adaptation of the robot behavioural models, all in real-time.

description: One of the exciting features of two-dimensional (2D) materials is their electronic and optical tunability through strain engineering. Previously, we found a class of 2D ferroelectric Rashba semiconductors PbX (X = S, Se, Te) with tunable spin-orbital properties. In this work, based on our previous tight-binding (TB) results, we derive an effective low-energy Hamiltonian around the symmetry points that captures the effects of strain on the electronic properties of PbX. We find that strains induce gauge fields which shift the Rashba point and modify the Rashba parameter. This effect is equivalent to the application of in-plane magnetic fields. The out-of-plane strain, which is proportional to the electric polarization, is also shown to modify the Rashba parameter. Overall, our theory connects strain and spin splitting in ferroelectric Rashba materials, which will be important to understand the strain-induced variations in local Rashba parameters that will occur in practical applications.

description: This paper explores the factors and theory behind the user-centered research that is necessary to create a successful game-like prototype, and user experience, for malicious users in a cybersecurity context. We explore what is known about successful addictive design in the fields of video games and gambling to understand the allure of breaking into a system, and the joy of thwarting the security to reach a goal or a reward of data. Based on the malicious user research, game user research, and using the GameFlow framework, we propose a novel malicious user experience design approach
Enhancement of spatial awareness in natural orifice transluminal endoscopic surgery
Creators: name: Karimyan, Vahe
Publisher: name: Imperial College London

description: Natural orifice transluminal endoscopic surgery (NOTES) represents a challenging concept to pursue in minimally invasive procedures, with a promise of becoming even less invasive, but with the additional issues of being team dependent and more technology intensive. The safety of patients undergoing any surgical procedure is of principal importance. When a surgeon performs laparoscopic procedures, he only has a two dimensional field of view and as a result, his spatial awareness is diminished. A surgeon operating under conditions of reduced spatial awareness poses an increased risk to a patient. Spatial awareness is deemed a necessary skill for the safe deployment of NOTES procedures. Understanding the surgeon’s situational and spatial awareness during NOTES investigation is therefore of paramount importance for the safe performance of this type of procedures. Enhancing scene visualisation, for instance by means of additional viewpoints or electromagnetic tracking, seems a feasible strategy for augmenting spatial awareness in NOTES. This study aims to propose novel approaches involving electromagnetic tracking and additional off-axis visualisation in an attempt to assess, as well as enhance spatial awareness of the operating field in NOTES. The original contributions of this thesis include: • Validation of an outlining approach to characterise spatial awareness in minimally invasive surgery particularly in NOTES • Qualitative and quantitative assessment of spatial awareness n NOTES • Identification of certain navigation behavioural patterns in NOTES • Design and evaluation of spatial awareness enhancement tool for NOTES The value of the research presented in this thesis, as well as the potential for further development is also discussed in the context of spatial awareness in MIS in general.
