Symbolic Crosschecking of Data-Parallel Floating Point Code
Creators: name: Collingbourne, Peter Cyrus
Publisher: name: Imperial College London
Year: 2012

description: In this thesis we present a symbolic execution-based technique for cross-checking programs accelerated using SIMD or OpenCL against an unaccelerated version, as well as a technique for detecting data races in OpenCL programs. Our techniques are implemented in KLEE-CL, a symbolic execution engine based on KLEE that supports symbolic reasoning on the equivalence between expressions involving both integer and floating-point operations. While the current generation of constraint solvers provide good support for integer arithmetic, there is little support available for floating-point arithmetic, due to the complexity inherent in such computations. The key insight behind our approach is that floating-point values are only reliably equal if they are essentially built by the same operations. This allows us to use an algorithm based on symbolic expression matching augmented with canonicalisation rules to determine path equivalence. Under symbolic execution, we have to verify equivalence along every feasible control-flow path. We reduce the branching factor of this process by aggressively merging conditionals, if-converting branches into select operations via an aggressive phi-node folding transformation. To support the Intel Streaming SIMD Extension (SSE) instruction set, we lower SSE instructions to equivalent generic vector operations, which in turn are interpreted in terms of primitive integer and floating-point operations. To support OpenCL programs, we symbolically model the OpenCL environment using an OpenCL runtime library targeted to symbolic execution. We detect data races by keeping track of all memory accesses using a memory log, and reporting a race whenever we detect that two accesses conflict. By representing the memory log symbolically, we are also able to detect races associated with symbolically indexed accesses of memory objects. We used KLEE-CL to find a number of issues in a variety of open source projects that use SSE and OpenCL, including mismatches between implementations, memory errors, race conditions and compiler bugs.
Contramodules over pro-perfect topological rings

description: For four wide classes of topological rings $\mathfrak R$, we show that all flat left $\mathfrak R$-contramodules have projective covers if and only if all flat left $\mathfrak R$-contramodules are projective if and only if all left $\mathfrak R$-contramodules have projective covers if and only if all descending chains of cyclic discrete right $\mathfrak R$-modules terminate if and only if all the discrete quotient rings of $\mathfrak R$ are left perfect. Three classes of topological rings for which this holds are the complete, separated topological associative rings with a base of neighborhoods of zero formed by open two-sided ideals such that either the ring is commutative, or it has a countable base of neighborhoods of zero, or it has only a finite number of semisimple discrete quotient rings. The fourth class consists of all the topological rings with a base of neighborhoods of zero formed by open right ideals which have a closed two-sided ideal with certain properties such that the quotient ring is a topological product of rings from the previous three classes. The key technique on which the proofs are based is the contramodule Nakayama lemma for topologically T-nilpotent ideals.

description: Target encoding plays a central role when learning Convolutional Neural Networks. In this realm, One-hot encoding is the most prevalent strategy due to its simplicity. However, this so widespread encoding schema assumes a flat label space, thus ignoring rich relationships existing among labels that can be exploited during training. In large-scale datasets, data does not span the full label space, but instead lies in a low-dimensional output manifold. Following this observation, we embed the targets into a low-dimensional space, drastically improving convergence speed while preserving accuracy. Our contribution is two fold: (i) We show that random projections of the label space are a valid tool to find such lower dimensional embeddings, boosting dramatically convergence rates at zero computational cost; and (ii) we propose a normalized eigenrepresentation of the class manifold that encodes the targets with minimal information loss, improving the accuracy of random projections encoding while enjoying the same convergence rates. Experiments on CIFAR-100, CUB200-2011, Imagenet, and MIT Places demonstrate that the proposed approach drastically improves convergence speed while reaching very competitive accuracy rates.

From Data to Architecture in the Neonatal Brain: Tractography Development and Comparison
Creators: name: Downing, Angela
Publisher: name: Imperial College London
Year: 2012

description: Reconstruction of white matter tracts in the neonatal brain offers valuable insight into the development and function of the brain. An accurate tractography algorithm is desirable for improving diagnosis and therapy for problems associated with premature birth. An investigation into tractography, beginning with the development of a minimal-model tractography algorithm and progressing to a comparison of established tractography methods is presented. A novel method of tractography is proposed for use with clinical diffusion weighted MR images for the reconstruction of white matter tracts in neonates. The principle behind the algorithm is to simulate the diffusion process directly, using diffusion measurements obtained in the acquisition to guide the tractography. Reconstructions of simulated and phantom data proved successful and were easily verified as the ground truth was known. However, two significant problems presented themselves with in vivo data. Discrimination between tissues in the brain proved to be a confounding factor to a tractography algorithm reliant on the diffusivity properties. Secondly, the lack of ground truth for comparison does not allow an accurate assessment of the reconstructed tracts. The need for a method of verification motivated the second part of the project which presents a comparison of established tractography methods in the parcellation of the thalamus in neonates. Four tractography algorithms were considered with different methods of initiating the tracks. Normalisation of the connectivity distributions used in the thalamus parcellation is proposed to eliminate bias in the results arising from variation in the topology of the cortex. The STAPLE algorithm was used to estimate the true segmentation from the candidate segmentations and this was used as the gold standard in the analysis. A whole brain approach to tractography with normalised connectivity was found to give the most consistent results in this group of subjects.

Radial migration of gap-opening planets in protoplanetary disks. I. The case of a single planet

description: A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk-planet interaction and migrates with the gap in the disk. It is expected that in the ideal case, a gap-opening planet migrates at the viscous drift speed, which is referred to as type II migration. However, recent hydrodynamic simulations have shown that in general, the gap-opening planet is not locked to the viscous disk evolution. A new physical model is required to explain the migration speed of such a planet. For this reason, we re-examined the migration of a planet in the disk, by carrying out the two-dimensional hydrodynamic simulations in a wide parameter range. We have found that the torque exerted on the gap-opening planet depends on the surface density at the bottom of the gap. The planet migration slows down as the surface density of the bottom of the gap decreases. Using the gap model developed in our previous studies, we have constructed an empirical formula of the migration speed of the gap-opening planets, which is consistent with the results given by the hydrodynamic simulations performed by us and other researchers. Our model easily explains why the migration speed of the gap-opening planets can be faster than the viscous gas drift speed. It can also predict the planet mass at which the type I migration is no longer adequate due to the gap development in the disk, providing a gap formation criterion based on planetary migration.

Kinetic simulations of relativistic magnetic reconnection with synchrotron and inverse Compton cooling

description: First results are presented from kinetic numerical simulations of relativistic collisionless magnetic reconnection in pair plasma that include radiation reaction from both synchrotron and inverse Compton (IC) processes, motivated by non-thermal high-energy astrophysical sources, including in particular blazars. These simulations are initiated from a configuration known as 'ABC fields' that evolves due to coalescence instability and generates thin current layers in its linear phase. Global radiative efficiencies, instability growth rates, time-dependent radiation spectra, lightcurves, variability statistics and the structure of current layers are investigated for a broad range of initial parameters. We find that the IC radiative signatures are generally similar to the synchrotron signatures. The luminosity ratio of IC to synchrotron spectral components, the Compton dominance, can be modified by more than one order of magnitude with respect to its nominal value. For very short cooling lengths, we find evidence for modification of the temperature profile across the current layers, no systematic compression of plasma density, and very consistent profiles of E.B. We decompose the profiles of E.B with the use of the Vlasov momentum equation, demonstrating a contribution from radiation reaction at the thickness scale consistent with the temperature profile.

Lock Inference for Java
Creators: name: Gudka, Khilan
Publisher: name: Imperial College London
Year: 2012

description: Atomicity is an important property for concurrent software, as it provides a stronger guarantee against errors caused by unanticipated thread interactions than race-freedom does. However, concurrency control in general is tricky to get right because current techniques are too low-level and error-prone. With the introduction of multicore processors, the problems are compounded. Consequently, a new software abstraction is gaining popularity to take care of concurrency control and the enforcing of atomicity properties, called atomic sections. One possible implementation of their semantics is to acquire a global lock upon entry to each atomic section, ensuring that they execute in mutual exclusion. However, this cripples concurrency, as non-interfering atomic sections cannot run in parallel. Transactional memory is another automated technique for providing atomicity, but relies on the ability to rollback conflicting atomic sections and thus places restrictions on the use of irreversible operations, such as I/O and system calls, or serialises all sections that use such features. Therefore, from a language designer's point of view, the challenge is to implement atomic sections without compromising performance or expressivity. This thesis explores the technique of lock inference, which infers a set of locks for each atomic section, while attempting to balance the requirements of maximal concurrency, minimal locking overhead and freedom from deadlock. We focus on lock-inference techniques for tackling large Java programs that make use of mature libraries. This improves upon existing work, which either (i) ignores libraries, (ii) requires library implementors to annotate which locks to take, or (iii) only considers accesses performed up to one-level deep in library call chains. As a result, each of these prior approaches may result in atomicity violations. This is a problem because even simple uses of I/O in Java programs can involve large amounts of library code. Our approach is the first to analyse library methods in full and thus able to soundly handle atomic sections involving complicated real-world side effects, while still permitting atomic sections to run concurrently in cases where their lock sets are disjoint. To validate our claims, we have implemented our techniques in Lockguard, a fully automatic tool that translates Java bytecode containing atomic sections to an equivalent program that uses locks instead. We show that our techniques scale well and despite protecting all library accesses, we obtain performance comparable to the original locking policy of our benchmarks.
Interventional Electrophysiology in Advanced Heart Disease Atrial Fibrillation and Heart Failure
Creators: name: Jones, David Gareth
Publisher: name: Imperial College London
Year: 2012

description: The optimal therapy for atrial fibrillation (AF) associated with heart failure (HF) is unclear. Drug-based rhythm control has not proved clinically beneficial. Catheter ablation-based rhythm control improves cardiac function in HF patients, but impact on physiological performance has not been formally evaluated in a randomised trial. A randomised trial was designed and conducted, comparing catheter ablation with rate control in adults with symptomatic heart failure, radionuclide left ventricular ejection fraction (EF) ≤35%, and persistent AF. The primary outcome was change in peak oxygen consumption (VO2) at cardiopulmonary exercise test. Secondary endpoints included change in quality of life (Minnesota), 6-minute walk, BNP, and EF. Patients were followed-up for 12 months, and results analysed by intention-to-treat. 52 patients (63±9y, EF 24±8%, VO2 17.3±5.1ml/kg/min) were randomised, 26 to each arm. In the ablation arm, at 12 month follow up, 88% maintained SR, with a single procedure success of 69%. In the rate control arm, rate criteria were achieved in 96% at 12 months. At 12 months, peak VO2 had increased by 2.13 (95%CI -0.1 to 4.36) ml/kg/min in the ablation arm, compared with a decrease (-0.94ml/kg/min, 95%CI -2.21 to 0.32) under rate control: mean benefit of ablation +3.07ml/kg/min, 95% CI 0.56-5.59, p=0.018. The change appeared progressive, with a difference of only 0.79ml/kg/min at 3 months (95% CI -1.01 to 2.60, p=0.38). Compared with rate control, ablation reduced 12-month Minnesota score (p=0.019) and BNP (p=0.045), and showed trends toward increased 6 min walk distance (p=0.095) and EF (p=0.055). LA size fell significantly after ablation (p=0.001). Catheter ablation of persistent AF in patients with HF, with the ablation strategy achieving sinus rhythm in the majority, improves prognostically important objective cardiopulmonary exercise performance, symptoms and neurohormonal status. The effects are clear at 1 year but less distinct earlier, suggesting a period of cardiac remodelling and recovery.
Reconfigurable Architectures for Cryptographic Systems
Creators: name: Le Masle, Adrien
Publisher: name: Imperial College London
Year: 2013

description: Field Programmable Gate Arrays (FPGAs) are suitable platforms for implementing cryptographic algorithms in hardware due to their flexibility, good performance and low power consumption. Computer security is becoming increasingly important and security requirements such as key sizes are quickly evolving. This creates the need for customisable hardware designs for cryptographic operations capable of covering a large design space. In this thesis we explore the four design dimensions relevant to cryptography - speed, area, power consumption and security of the crypto-system - by developing parametric designs for public-key generation and encryption as well as side-channel attack countermeasures. There are four contributions. First, we present new architectures for Montgomery multiplication and exponentiation based on variable pipelining and variable serial replication. Our implementations of these architectures are compared to the best implementations in the literature and the design space is explored in terms of speed and area trade-offs. Second, we generalise our Montgomery multiplier design ideas by developing a parametric model to allow rapid optimisation of a general class of algorithms containing loops with dependencies carried from one iteration to the next. By predicting the throughput and the area of the design, our model facilitates and speeds up design space exploration. Third, we develop new architectures for primality testing including the first hardware architecture for the NIST approved Lucas primality test. We explore the area, speed and power consumption trade-offs by comparing our Lucas architectures on CPU, FPGA and ASIC. Finally, we tackle the security issue by presenting two novel power attack countermeasures based on on-chip power monitoring. Our constant power framework uses a closed-loop control system to keep the power consumption of any FPGA implementation constant. Our attack detection framework uses a network of ring-oscillators to detect the insertion of a shunt resistor-based power measurement circuit on a device's power rail. This countermeasure is lightweight and has a relatively low power overhead compared to existing masking and hiding countermeasures.

Modelling the Flow and Transport Properties of Two-Dimensional Fracture Networks, Including the Effect of Stress
Creators: name: Leung, Colin Tsee-On
Publisher: name: Imperial College London
Year: 2012

description: This thesis focuses on the effective hydraulic transmissivity of two-dimensional fracture networks in rocks. The main simulation tool used in this work is the discrete fracture network code NAPSAC. There are four main topics in this thesis: (1) estimating permeability from network properties, (2) comparing discrete fracture network with effective continuum models, (3) using DFN for hydro-mechanical coupled modelling, and (4) solute transport simulations. For fracture networks with uniform aperture, the permeability can be estimated using segment density, fracture density, and fracture lengths of the fracture network. For fracture networks with apertures directly proportional to their lengths, the individual conductance of each of the fracture segments was used to calculate an effective conductance for the whole network. The arithmetic mean of the segment conductance gives a good approximation for the effective conductance of the whole network. A series of effective continuum models of a fracture network were created using different element sizes, and their flow behaviours were compared against results obtained from discrete fracture network model. The permeability tensors of each of the elements in the effective continuum meshes were calculated using discrete fracture network methods. It was found that the flow through effective continuum model with any element size gave good agreement with the discrete fracture network results. Hydro-mechanical coupled simulations were carried out using NAPSAC, where the applied far field stresses are applied to each fractures independently. Simulations were then carried out using the distinct element code UDEC to justify the simplified physics used in NAPSAC. It was shown that for random 2D fracture networks under a range of loadings, NAPSAC and UDEC seem to predict similar overall flows. Different ways for modelling the effects of rock matrix diffusion were explored. The significance of rock matrix diffusion, as well as the diffusion distance, was linked to the magnitude of the pressure gradient across the fracture network. A semi-analytical method for estimating the diffusion distance was proposed: using the perimeter and the area of each of the matrix blocks, it is possible to estimate the diffusion distance using the 'shape factor' concept.

description: We have scanned 5000 deg$^{2}$ of Southern Sky to search for strongly lensed quasars with five methods, all source-oriented, but based on different assumptions and selection criteria. We analyse morphological searches based on Gaia multiplet detection and chromatic offsets, fibre-spectroscopic preselection, and X-ray and radio preselection. The performance and complementarity of the methods are evaluated on a common sample of known lenses in the Dark Energy Survey public DR1 footprint. We recovered in total 13 known lenses, of which 8 quadruplets. The method that found the largest number of known lenses is the one based on morphological and colour selection of objects from the WISE and Gaia-DR2 Surveys. We finally present a list of high-grade candidates from each method, to facilitate follow-up spectroscopic campaigns, including two previously unknown quadruplets: WG210014.9-445206.4 and WG021416.37-210535.3.

description: Doyon Utilities (Doyon) planned to rebuild an existing 34.5KV above ground feeder line in order to improve the current Joint Base Elmendorf-Richardson (JBER) electrical distribution system. The project would add to the overall capability of the existing 34.5KV line, which could distribute landfill gas facility (LGS) generated power through the JBER electrical grid. Doyon contracted Northern Land Use Research Alaska, LLC (NLURA) to conduct a Phase II cultural resource survey of the proposed right of way (ROW) for the transmission line. This report is the final cultural resources report for NLURA's survey of the Doyon Utilities (DOYON) 34.5KV Transmission Line. This document also includes a letter to the Alaska State Historic Preservation Office regarding the project.

Small waterbody fisheries and the potential for community-led enhancement: case studies in Lao PDR
Creators: name: Garaway, Caroline Jane
Publisher: name: Imperial College London
Year: 1999

description: Based on case studies in Lao PDR, this research investigates the importance of small waterbody fisheries to rural households, the impact of enhancement initiatives on resources and resource users, and the opportunities and constraints of communityled enhancement. Detailed biological, socio-economic, and institutional data on small water body fisheries were collected and analysed in an integrated framework. Small waterbody fisheries contributed substantially to rural livelihoods, with average household catches of 66 kg/year, equivalent in value to approximately half the household rice production (the major crop grown in the region). Poorer households caught and sold more fish than other socio-economic groups. Active management of small waterbody fisheries by stocking and the regulation of fishing had significant impacts on fish stocks, yields, and the type, magnitude and distribution of benefits to villagers. Stocked fisheries managed by and for the village showed higher standing stocks and returns to fishing effort, and thus generated substantial efficiency benefits even though yields were not significantly higher than in unmanaged fisheries. Benefits were in the form of income to the community, partially passed on to households, (equally between socio-economic groups), through reduced financial contributions to the village. Institutional analysis suggests that locally adapted rules, ownership rights, low cost monitoring and enforcement, and information about benefits are key factors in promoting and sustaining community enhancement efforts, as well as the presence of individuals with substantial leadership skills. Results suggest that communities can and do successfully set up and maintain enhancement initiatives and that enhancement of small water body fisheries can generate substantial benefits. However these will only be sustained if it corresponds to villager's objectives and coincides with conducive institutional arrangements and, crucially, an enabling external policy environment. To achieve the full potential of enhancements, research should be aimed at furthering villager's understanding of the status and potential of their resource in terms of these objectives.
Dark Matter Halo Structure in CDM Hydrodynamical Simulations

description: We have carried out a comparative analysis of the properties of dark matter halos in N-body and hydrodynamical simulations. We analyze their density profiles, shapes and kinematical properties with the aim of assessing the effects that hydrodynamical processes might produce on the evolution of the dark matter component. The simulations performed allow us to reproduce dark matter halos with high resolution, although the range of circular velocities is limited. We find that for halos with circular velocities of $[150-200] km s^{-1}$ at the virial radius, the presence of baryons affects the evolution of the dark matter component in the central region modifying the density profiles, shapes and velocity dispersions. We also analyze the rotation velocity curves of disk-like structures and compare them with observational results.

Travelling wave-based fault location algorithm for power systems
Creators: name: Ogbonnaya Ibe, Anthony
Publisher: name: Imperial College London
Year: 1984

description: This thesis describes the development of an accurate method of f a u l t location in transmission lines and cables. While the presence of a high frequency transient superimposed on the 50 Hz f a u l t voltage and current waveforms must be removed for most of the transmission l i ne protection methods, the method presented in this thesis, which draws from t r a v e l l i n g wave principles, locates the f a u l t position using recordings from the f a u l t waveform independent of the frequency components present. Using the telegraph equations as a l i ne model, voltage and current samples taken at one end of a l i ne within the f i r s t 5 ms of f a u l t inception were used to generate instantaneous voltage and current p r o f i l e s for the rest of the transmission l i n e . The voltage and current estimation were based on the solution of the equations of the l i n e model by the method of characteristics. Different c r i t e r i a functions, involving the computed variables were applied to determine the f a u l t positions. The basic functions involve any one of the square of the voltage, the square of the current or the product of the two. Fault position is determined by the turning or inflexionary point in the functions. In a further development the variation of the tangent to the functions described was considered and the f a u l t position was found to be indicated by the peak of the scatter diagram produced. This l a t t e r function finds special application for resistive faults and f a u l t s in teed networks where the turning point given by the e a r l i e r functions are not usually well defined. The algorithm has been tested both with laboratory simulations and d i g i t a l computer simulated data on typical 33 kV, 132 kV and 400 kV systems. Fault location accuracies of between 0.1% to 3.3% were achieved. Following the success with laboratory tests on models, a -proposal has been put forward for an on-line f a u l t locator.
Cold-Source Noise Measurement of a Differential Input Single-Ended Output Low-Noise Amplifier Connected to a Low-Frequency Radio Astronomy Antenna

description: We present two methods for measuring the noise temperature of a differential input single-ended output (DISO) Low-Noise Amplifier (LNA) connected to an antenna. The first method is direct measurement of the DISO LNA and antenna in an anechoic chamber at ambient temperature. The second is a simple and low-cost noise parameter extraction of the DISO device using a coaxial long cable. The reconstruction of the DISO noise parameter from the noise wave measurements of the DISO LNA with one terminated input port is discussed in detail. We successfully applied these methods to the Murchison Widefield Array LNA and antenna.

(Anti-)Instantons and the Atiyah-Hitchin Manifold

description: The Atiyah-Hitchin manifold arises in many different contexts, ranging from its original occurrence as the moduli space of two SU(2) 't Hooft-Polyakov monopoles in 3+1 dimensions, to supersymmetric backgrounds of string theory. In all these settings, (super)symmetries require the metric to be hyperkähler and have an SO(3) transitive isometry, which in the four-dimensional case essentially selects out the Atiyah-Hitchin manifold as the only such smooth manifold with the correct topology at infinity. In this paper, we analyze the exponentially small corrections to the asymptotic limit, and interpret them as infinite series of instanton corrections in these various settings. Unexpectedly, the relevant configurations turn out to be bound states of $n$ instantons and $\bar n$ anti-instantons, with $|n-\bar n|=0,1$ as required by charge conservation. We propose that the semi-classical configurations relevant for the higher monopole moduli space are Euclidean open branes stretched between the monopoles.
