Decision making and efficient surrogate-assisted optimisation techniques under uncertainty: application to CO2 sequestration
Creators: name: Petvipusit, Rachares
Publisher: name: Imperial College London
Year: 2015

description: One promising proposal to mitigate the effect of climate change as a result of high atmo- spheric CO2 concentrations is carbon capture and storage. Deep saline aquifers provide the most storage capacity for CO2 storage. However, their geological characteristics are often poorly defined, which makes it difficult to design CO2 sequestration operations. This thesis considers how CO2 sequestration can be performed effectively and efficiently under geological uncertainty by allocating injection rates among injectors to maximise economic performance criteria and simultaneously minimise the risk of CO2 leakage. To this end, we consider the following four challenges in this thesis. 1.) Optimisation of CO2 injection strategies is a time-consuming operation since it re- quires multiple evaluations of expensive black-box functions. This computational cost increases rapidly when accounting for the impact of geological uncertainty. In this thesis, we propose the use of adaptive sparse grid interpolation (ASGI) to speed up the CO2 optimisation process. Based on numerical results, the ASGI is an efficient surrogate technique and will be used throughout the thesis. 2.) Injection designs for CO2 sequestration is difficult when the geology of the storage formation is not well-defined. In the thesis, we propose a utility function to find the injection strategy that is insensitive to the impact of geological uncertainty. Numeri- cal results show potential benefits of using the utility function for the optimisation of CO2 under geological uncertainty. 3.) Optimisation of CO2 sequestration for several conflicting criteria is a challenging task. In the thesis, we use a non-dominated sorting genetic algorithm (NSGA-II) coupled with the ASGI surrogate to maximise both economic performance and sweep efficiency of CO2 flooding while simultaneously minimising the risks of CO2 leakage. Solutions obtained from the NSGA method help decision makers to manage multiple conflicting criteria for CO2 sequestration. 4.) The ASGI surrogate is an efficient surrogate-assisted optimisation technique for a small to moderate number of input variables, but for problems with 10s of control parameters, it suffers from the curse of dimensionality — the computational time increases exponentially with the number of input variables. In the thesis, we develop a high-dimensional model representation (HDMR) technique to efficiently map the input-output relationship of a function. Several numerical examples show that the HDMR approach is suitable for CO2 storage optimisation with many input variables.

Transiently immobilised n-heterocyclic carbenes: boomerang organocatalysts
Creators: name: Lee, Fu-Howe
Publisher: name: Imperial College London
Year: 2014

description: There have been reports in the literature on N-Heterocyclic Carbene - Silicon (NHC·Si) interactions and their involvement in organocatalytic cycles. However, there is little experimental evidence to support this postulation. Indeed, other plausible mechanisms that do not invoke an NHC·Si interaction can be drawn. We show that there is insufficient evidence to support the postulated NHC·Si interaction in the protection of NHCs by silicones reported by Baceiredo and co-workers. The synthesis and use of 13C-labelled NHCs allowed for the clear monitoring of the carbene moiety by 13C NMR spectroscopy. 1H, 13C and 29Si NMR spectra did not indicate the formation of NHC·Si complexes at temperatures from 298K to 198K in toluene-d8 or THF-d8 for a range of silicones and low molecular weight silicon species of varying Lewis-acidities. DOSY spectra did not show specific or non-specific interactions between NHCs and silicon species in solution, which would have been expected for an NHC·Si interaction. In situ IR measurements of a model NHC-catalysed reaction of methyl 2-phenylacetate with ethanolamine also failed to provide conclusive evidence of an NHC·Si interaction which would lead to diminished rates of reaction. Furthermore, computational studies of the above systems do not predict an NHC·Si interaction. Simulations predict that the formation of such NHC·Si interactions is thermodynamically disfavoured at room temperature based on Gibbs free energies calculated at the MP2/aug-cc-pVTZ//B3LYP/6-311+G(d,p) level. Mass-transfer analysis, as applied to the systems described by Baceiredo and co-workers, show that retardation of decomposition can be explained by steady-state mass-transfer limited by diffusion of oxygen without the need to invoke a NHC·Si interaction. The analytical solution of transient mass transfer shows that protection afforded by diffusion is non-linear and that the evolution of the concentration profile is proportional to e^(Dt/L^2), where D is the diffusion coefficient, t is time, and L the non-dimensional length.

description: PyPSA-Eur, the first open model dataset of the European power system at the transmission network level to cover the full ENTSO-E area, is presented. It contains 6001 lines (alternating current lines at and above 220 kV voltage level and all high voltage direct current lines), 3657 substations, a new open database of conventional power plants, time series for electrical demand and variable renewable generator availability, and geographic potentials for the expansion of wind and solar power. The model is suitable both for operational studies and generation and transmission expansion planning studies. The continental scope and highly resolved spatial scale enables a proper description of the long-range smoothing effects for renewable power generation and their varying resource availability. The restriction to freely available and open data encourages the open exchange of model data developments and eases the comparison of model results. A further novelty of the dataset is the publication of the full, automated software pipeline to assemble the load-flow-ready model from the original datasets, which enables easy replacement and improvement of the individual parts. This paper focuses on the description of the network topology, the compilation of a European power plant database and a top-down load time-series regionalisation. It summarises the derivation of renewable wind and solar availability time-series from re-analysis weather datasets and the estimation of renewable capacity potentials restricted by land-use. Finally, validations of the dataset are presented, including a new methodology to compare geo-referenced network datasets to one another.

description: The solute carrier 17 (SLC17) family contains anion transporters that accumulate neurotransmitters in secretory vesicles, remove carboxylated monosaccharides from lysosomes, or extrude organic anions from the kidneys and the liver. We combined experimental and computational approaches to describe the transport mechanisms of a model bacterial protein, the D-galactonate transporter DgoT, at atomic resolution. We found that protonation of D46 and E133 precedes galacto-nate binding and that substrate binding induces closure of the extracellular gate, with the conserved R47 coupling substrate binding to transmembrane helix movement. After isomerization to an inward-facing conformation, deprotonation of E133 and subsequent proton transfer from D46 to E133 opens the intracellular gate and permits galactonate dissociation. After release of the second proton, apo DgoT returns to the outward-facing conformation. Our results provide a framework to understand how various SLC17 transport functions with distinct transport stoichiometries can be attained through subtle variations in proton and substrate binding/unbinding.

description: This is the first part of a study of the detailed X-ray properties of the cores of nearby clusters. We have used the flux-limited sample of 55 clusters of Edge et al. (1990) and archival and proprietary data from the {\it ROSAT} observatory. In this paper an X-ray spatial analysis based on the surface-brightness-deprojection technique is applied to the clusters in the sample with the aim of studying their cooling flow properties. We determine the fraction of cooling flows in this sample to be 70-90 percent and estimate the contribution of the flow region to the cluster X-ray luminosity. We show that the luminosity within a strong cooling flow can account for up to 70 percent of a cluster X-ray bolometric luminosity. Our analysis indicates that about 40 percent of the clusters in the sample have flows depositing more than 100 \Msunpyr throughout the cooling region and that these possibly have been undisturbed for many Gyr, confirming that cooling flows are the natural state of cluster cores. New cooling flows in the sample are presented and previously ambiguous ones are clarified. We have constructed a catalogue of some intracluster medium properties for the clusters in this sample. The profiles of the mass deposited from cooling flows are analyzed and evidence presented for the existence of breaks in some of the profiles. Comparison is made to recent optical and radio data. We cross-correlate our sample with the Green Bank, NVSS and FIRST surveys and to the volume-limited sample of brightest cluster galaxies presented by Lauer and Postman (1994). Although weak trends exist, no strong correlation between optical magnitude or radio power of the brightest cluster galaxy and the strength of the flow is found.

description: Using spatial modes for quantum key distribution (QKD) has become highly topical due to their infinite dimensionality, promising high information capacity per photon. However, spatial distortions reduce the feasible secret key rates and compromise the security of a quantum channel. In an extreme form such a distortion might be a physical obstacle, impeding line-of-sight for free-space channels. Here, by controlling the radial degree of freedom of a photon's spatial mode, we are able to demonstrate hybrid high-dimensional QKD through obstacles with self-reconstructing single photons. We construct high-dimensional mutually unbiased bases using spin-orbit hybrid states that are radially modulated with a non-diffracting Bessel-Gaussian (BG) profile, and show secure transmission through partially obstructed quantum links. Using a prepare-measure protocol we report higher quantum state self-reconstruction and information retention for the non-diffracting BG modes as compared to Laguerre-Gaussian modes, obtaining a quantum bit error rate (QBER) that is up to 3 times lower. This work highlights the importance of controlling the radial mode of single photons in quantum information processing and communication as well as the advantages of QKD with hybrid states.

description: We study models that interpolate between an elementary and a composite Higgs boson. Such models, arising in theories with new vector-like fermions with electro-weak quantum numbers and charged under a confining gauge interaction, are entirely compatible with current data, with only weak bounds from flavor, CP-violation and precision tests. After classifying the models from the point of view of symmetries, we study their collider phenomenology at LHC. In the most relevant scenarios, bounds from present searches exclude heavy scalar isospin triplets and quintuplets up to $\sim 200\;$GeV and we show how dedicated searches of simple signals such as $pp\to 3 γW$ could improve the reach by at least a factor of 2 with present data, reaching $O(1\;{\rm TeV})$ with higher integrated luminosities. States that mix with the SM Higgs can be tested in a variety of final states, such as $2b2γ$ searches relevant for double Higgs production.

Ultra low power wearable sleep diagnostic systems

Publisher: name: Imperial College London

description: Sleep disorders are studied using sleep study systems called Polysomnography that records several biophysical parameters during sleep. However, these are bulky and are typically located in a medical facility where patient monitoring is costly and quite inefficient. Home-based portable systems solve these problems to an extent but they record only a minimal number of channels due to limited battery life. To surmount this, wearable sleep system are desired which need to be unobtrusive and have long battery life. In this thesis, a novel sleep system architecture is presented that enables the design of an ultra low power sleep diagnostic system. This architecture is capable of extending the recording time to 120 hours in a wearable system which is an order of magnitude improvement over commercial wearable systems that record for about 12 hours. This architecture has in effect reduced the average power consumption of 5-6 mW per channel to less than 500 uW per channel. This has been achieved by eliminating sampled data architecture, reducing the wireless transmission rate and by moving the sleep scoring to the sensors. Further, ultra low power instrumentation amplifiers have been designed to operate in weak inversion region to support this architecture. A 40 dB chopper-stabilised low power instrumentation amplifiers to process EEG were designed and tested to operate from 1.0 V consuming just 3.1 uW for peak mode operation with DC servo loop. A 50 dB non-EEG amplifier continuous-time bandpass amplifier with a consumption of 400 nW was also fabricated and tested. Both the amplifiers achieved a high CMRR and impedance that are critical for wearable systems. Combining these amplifiers with the novel architecture enables the design of an ultra low power sleep recording system. This reduces the size of the battery required and hence enables a truly wearable system.

description: In the research described here polyvinyl butyral (PVB) samples with mass acetalization degrees of 84.4%, 70.4%, 58.8%, 40.3% and number-average molecular weights (Mn) of 29300 ∼ 36100 g mol−1 were synthesized using p-toluenesulfonic acid as a catalyst. The PVB samples were characterized by gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and differential thermogravimetric analysis (DTGA). Furthermore, the solubility parameters of the PVB with different acetalization degrees were determined by the Hansen Solubility Parameter in Practice (HSPiP) software, turbidimetric titration and group contribution methods. The results showed that the total solubility parameter (δt) and two of the solubility parameter components (polar solubility parameter δp and hydrogen bonding solubility parameter δh) increased linearly with the decrease of the acetalization degree of the PVB, while the change of δd (dispersion solubility parameter) was not obvious. The correlation between the solubility parameters and acetalization degree of PVB was established. The solubility parameters obtained in this paper can be used to predict the affinity of PVB with solvents or additives, which is convenient for solvent selection and formulation design.

description: Gravitational waves from spin-precessing binaries exhibit amplitude oscillations that provide an invaluable method to extract the spins of the inspiraling compact objects. The spin-spin and spin-orbit interactions that cause this effect are sensitive to the fundamental nature of gravity, which will allow us to constrain modified theories of gravity using gravitational wave observations of precessing binaries. We here consider precessing black hole binaries in dynamical Chern-Simons gravity, an effective theory of gravity that enhances parity violating interactions. We model the black holes as modified point particles using effective field theory, and derive the spin-precession equations for a binary system by working within the post-Newtonian formalism. We find that the spin-spin and quadrupole-monopole interactions of General Relativity are modified due to an interaction between the scalar dipoles of the two black holes and the modified black hole quadrupole as a result of the violation of the no hair theorems. These modifications enter the precession equations at leading post-Newtonian order. We further show that these precession equations admit seven constants of motion when neglecting radiation reaction, with only the mass-weighted effective spin being modified from General Relativity. We discuss how these may be used to reduce the precession equations to quadrature and the possibility of constructing analytic Fourier domain waveforms for generic spin-precessing binaries in dCS gravity.

description: It is shown that odd harmonic azimuthal correlations, including the directed flow $v_1$, in forward two-particle production in peripheral proton-nucleus ($pA$) collisions can arise simply from the radial nuclear profile of a large nucleus. This requires consideration of the C-odd part of the gluonic generalized transverse momentum dependent (GTMD) correlator of nucleons in the nucleus. The gluonic GTMD correlator is the Fourier transform of an off-forward hadronic matrix element containing gluonic field strength tensors that are connected by gauge links. It is parametrized in terms of various gluon GTMD distribution functions (GTMDs). We show (in a gauge invariant way) that for the relevant dipole-type gauge link structure in the small-$x$ limit the GTMD correlator reduces to a generalized Wilson loop correlator. The Wilson loop correlator is parametrized in terms of a single function, implying that in the region of small $x$ there is only one independent dipole-type GTMD, which can have a C-odd part. We show that the odderon Wigner distribution, which is related to this C-odd dipole GTMD by a Fourier transform, generates odd harmonics in the two-particle azimuthal correlations in peripheral $pA$ collisions. We calculate the first odd harmonic $v_1$ for forward production within the color glass condensate framework in the limit of a large number of colors. We find that nonzero odd harmonics are present without breaking the rotational symmetry of the nucleus, arising just from its inhomogeneity in the radial direction. Using a CGC model with a cubic action, we illustrate that percent level $v_1$ can arise from this C-odd mechanism. In contrast, we show that only even harmonics arise in diffractive dijet production in ultra-peripheral $pA$ collisions where this gluon dipole GTMD also appears.

Hands-on Tutorial Deploying Kubernetes and JupyterHub on Jetstream

subject: FOS: Computer and information sciences

description: Jupyter Notebooks have become a mainstream tool for interactive computing in every field of science. Being a web-based platform, they are naturally suited to serve as companion application to Science Gateways: a scientist can use a Jupyter Notebook in their browser to pre-process inputs, launch a job on the Science Gateway via web API and then access, analyze, plot and postprocess the job outputs, without ever worrying about setting up and keeping updated their software environment.The JupyterHub project provides a multiple-user platform for Jupyter Notebooks and it is very easy to install and configure on a single server. However, when we need to provide computational resources to a large pool of users, we need to distribute the users on a cluster of machines, the best way to achieve scalability is thanks to the container orchestration platform Kubernetes.In this tutorial we will work through the installation of Kubernetes on a set of Jetstream Virtual Machines, setup persistent storage and install a bare-bone JupyterHub deployment using the zero-to-jupyterhub recipe provided by the Jupyter team.Then we will customize the setup configuring authentication (XSEDE, Globus or Github), choosing our preferred software environment for the users via Docker.Finally we will show how to execute computational jobs, either interfacing with the web APIs of a “test gateway” to submit jobs or launching a pool of workers on Kubernetes and execute a distributed computation (using dask).
Magnetocaloric effect and thermal transport management in lanthanum manganites
Creators: name: Turcaud, Jeremy
Publisher: name: Imperial College London
Year: 2014

description: This thesis investigates two challenges associated with the use of manganites for magnetocaloric applications. The first challenge is associated with methods to engineer the thermal conductivity, K. The second challenge is to understand the limits of the entropy change achievable in magnetocaloric manganites. Thermal management has been achieved via different microstructuring routes and their influence on thermal transport properties such as K, resistivity and thermopower, have been studied. A factor of two increase in K is demonstrated by using density and grain size optimization, while three-fold and six-fold increases are seen by employing the introduction of a second highly conductive phase via: (1) silver impregnation and silver particle coating and (2) copper electroplating, respectively. Understanding the magnetocaloric effect (MCE) characteristics in manganites has been achieved by bringing together magnetisation, magneto-structural, magneto-Seebeck, and neutron diffraction independent measurements. We first show that the temperature T* up to which a spontaneous magnetisation is observed in the inverse magnetic susceptibility of La0.7Ca0.3MnO3 and La0.7Ba0.3MnO3 above Tc, is related to the transition temperature of the low temperature (high-magnetic field and high-magnetisation) magnetic phase. In the most widely studied La(1-x)CaxMnO3 (x = 0.2, 0.25, 0.3), we then conclude that unlike between the degree of static Jahn-Teller distortion and the interval [T*-Tc]/Tc where we show that there exists a close relationship, there is no apparent correlation between the magnitude of the MCE and [T*-Tc]/Tc . We then unravel the competing strength of the various degrees of freedom and show that the inhibition of a large magnetocaloric response is due to the strong correlations that underpin the collosal magnetoresistance effect: both clustering of magnetic Mn atoms due to polaron formation and the insulator to metal transition. Finally we discuss prospects to improve material properties for application in light of these findings.

description: The isothermal gravitational collapse and fragmentation of a region within a molecular cloud and the subsequent formation of a protostellar cluster is investigated numerically. The clump mass spectrum which forms during the fragmentation phase can be well approximated by a power law distribution dN/dM ~ M^(-1.5). In contrast, the mass spectrum of protostellar cores that form in the centers of Jeans-unstable clumps and evolve through accretion and N-body interactions is described by a log-normal distribution with a width that is in excellent agreement with observations of multiple stellar systems.

Dynamically induced heat rectification in quantum systems

description: Heat rectifiers are systems that conduct heat asymmetrically for forward and reversed temperature gradients. Here, we present an analytical study of heat rectification in linear quantum systems. We demonstrate that asymmetric heat currents can be induced in a linear system only if it is dynamically driven. The rectification can be further enhanced, even achieving maximal performance, by detuning the oscillators of the driven network. Finally, we demonstrate the feasibility of such driven harmonic network to work as a thermal transistor, quantifying its efficiency through the dynamical amplification factor.

Nucleon-Antinucleon Annihilation in Large Nc QCD with rho and omega Mesons

description: We use classical/large Nc (number of colors) QCD to study nucleon--antinucleon annihilation at rest. We include pion, rho and omega fields in the classical dynamics, starting from the nonlinear sigma model. We begin with a spherical blob of pionic matter with zero baryon number and energy of twice the nucleon mass. This evolves according to the classical dynamics to pion and vector meson fields into the radiation zone. The radiation fields are quantized using the method of coherent states modified to include isospin and four momentum conservation. Empirical information is extracted from that coherent state. We find good agreement with data for single particle momentum and number spectra, and with branching ratios to many annihilation channels. All this emerges with nearly no free parameters.

Breakdown to turbulence in non-Newtonian flow
Creators: name: Agarwal, Akshat
Publisher: name: Imperial College London
Year: 2014

description: Transition to turbulence in polymeric channel flow is investigated, with the FENE-P model used to characterize the viscoelastic behaviour of the flow. Simulations are performed to study transition through both the natural and bypass routes. In the linear growth regime of natural transition, differences in the growth rate of a TS wave are explained by appealing to the production of the perturbation energy budget. At high Weissenberg number, the growth rate is substantially lower in comparison to Newtonian flow. As a result, the transition process is prolonged. Upon the introduction of three dimensional disturbances, Newtonian and non-Newtonian cases undergo transition through the H-type instability. The spanwise extent of the lambda structures during transition is larger in non-Newtonian flow. Bypass transition is initiated by an initially-localized disturbance. In the linear growth regime, the flow response is stabilized by viscoelasticity, and the maximum attainable disturbance-energy amplification is reduced with increasing polymer concentration. The reduction in the energy growth rate is attributed to the polymer work, which plays a dual role: First, a spanwise polymer-work term develops, and is explained by the tilting action of the wall-normal vorticity on the mean streamwise conformation tensor. This resistive term weakens the spanwise velocity perturbation thus reducing the energy of the localized disturbance. The second action of the polymer is analogous, with a wall-normal polymer work term that weakens the vertical velocity perturbation. Its indirect effect on energy growth is substantial since it reduces the production of Reynolds shear stress and in turn of the streamwise velocity perturbation, or streaks. During the early stages of non-linear growth, the dominant effect of the polymer is to suppress the large scale streaky structures which are strongly amplified in Newtonian flows. As a result, the process of transition to turbulence is prolonged and, after transition, a drag reduced turbulent state is attained.

description: A combination of the variable-constant and complex coordinate rotation methods is used to solve the two-body Schrödinger equation. The latter is replaced by a system of linear first-order differential equations, which enables one to perform direct calculation of the Jost function for all complex momenta of physical interest, including the spectral points corresponding to bound and resonance states. Explicit forms of the equations, appropriate for central, noncentral, and Coulomb-tailed potentials are given. Within the proposed method, the scattering, bound, virtual, and resonance state problems can be treated in a unified way. The effectiveness of the method is demonstrated by a numerical example.

Fine structure of the red giant clump from HIPPARCOS data, and distance determinations based on its mean magnitude

description: The I-band brightness of clump stars has been used recently to determine the distance to the bulge, the LMC and SMC, and to M31. It was assumed to be a standard candle based on the observational fact that it is independent of (V-I)-colour in all observed populations. The calibration was done using nearby clump stars with HIPPARCOS-parallaxes. The most surprising result of this procedure was the claim that the distance to the LMC was only 18.04 mag. In the present paper we show that with a population synthesis approach we can reproduce the constancy of M_I with colour for the local Hipparcos clump sample. Nevertheless, M_I is not a constant among different populations, but depends on metallicity. As a result, the determined distance modulus to the LMC of 18.28+-0.18 mag is in better agreement with standard values. This resolves, at least partially, the controversial result obtained by the assumption of a universal value for M_I. We also find and discuss substructures in the clump: we predict that stars slightly heavier than the maximum mass for developing degenerate He cores should define a secondary, clumpy structure, about 0.3 mag below the bluest extremity of the red clump. This secondary clump can be clearly identified in the HIPPARCOS database of stars. We argue that there remain severe uncertainties in the use of clump stars as a distance indicator.
