Guided wave monitoring of pipelines
Creators: name: Dobson, Jacob
Publisher: name: Imperial College London
Year: 2015

description: Guided wave sensors are commonly used in the oil and gas industry to inspect pipework for damage. Early sensor were detachable and designed for single inspections, but current best practice is to permanently attach sensors and take repeat readings. Known as a monitoring configuration, this approach offers potential benefits in terms of cost, defect detection capability and safety. There are however implementation challenges that are still to be resolved, particularly the need to compensate collected data for changes in environmental and operational conditions. The interaction of guided waves with general corrosion is also poorly understood. This thesis seeks to address both issues, beginning with a finite element study of the interaction of guided waves with rough surfaces. These rough surfaces are a basic model for general corrosion and this study shows that attenuation seen in commercial inspections can be explained by significant scattering of waves by the rough surface. This scattering is shown to be a function of the rough surface characteristics, pipe diameter and inspection wave frequency. This study was computationally expensive and made possible by recently developed simulation tools, particularly graphics processing unit based solvers. The development and construction of these simulation tools is described in detail. The second major theme of this thesis is improved signal processing for monitoring data based on Independent Component Analysis [ICA]. ICA was applied to numerous example signals and found to correctly separate structural anomalies from surrounding noise. This technique was then compared to best practice techniques from industry (residual processing and singular value decomposition [SVD]) and it was found that SVD and ICA performed much better than residual processing under a range of conditions. In general ICA performed better than SVD, but was less robust to outlier behavior. The framework used for this comparison is itself novel and is described.

description: The PSR B1259--63 system contains a 47 ms radio pulsar in a highly eccentric binary with a Be-star companion. Strongly time variable X-ray emission was reported from this system as the pulsar was near apastron in 1992-early 1993. The variability was primarily deduced from an apparent non-detection of the \psr system during a first pre-apastron \ros observation in February~1992. We have re-analyzed the \ros observations of the \psr system. Contrary to the results of a previous analysis, we find that the \psr system was detected by \ros during the first off-axis February~1992 observation. The intensity of the soft X-ray emission of the \psr system before and after the 1992 apastron appears to vary at most by a factor $\sim 2$. Our results sensibly constrain theoretical models of X-ray emission from the \psr system.

Strong gravitational lensing by spiral galaxies

Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate gravitational lensing by a realistic model of disk galaxies. Most of the mass is contained in a large spherical isothermal dark matter halo, but the potential is modified significantly in the core by a gravitationally-dominant exponential disk. The method used is adapted from a very general multi-lens ray-tracing technique developed by Moeller. We investigate the effects of the disk-to-halo mass ratio, the disk scale length, the disk inclination to the line of sight and the lens redshift on two strong-lensing cross sections: the cross section for multiple imaging, and the cross section for large magnifications, in excess of a factor of 10. We find that the multiple-imaging cross section can be enhanced significantly by an almost edge-on Milky Way disk as compared with a singular isothermal sphere (SIS) in individual cases; however, when averaged over all disk inclinations, the cross section is only increased by about fifty per cent. These results are consistent with other recent work. The presence of a disk, however, increases the inclination-averaged high-magnification cross section by an order of magnitude as compared with a SIS. This result has important implications for magnification bias in future lens surveys, particularly those in the submillimetre waveband, where dust extinction in the lensing galaxy has no effect on the brightness of the images.

Transient Emission From Dissipative Fronts in Magnetized, Relativistic Outflows. I. Gamma-Ray Flares
Creators: name: Levinson, Amir
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The transient emission produced behind internal shocks that are driven by overtaking collisions of a magnetized, relativistic outflow is considered. A self-consistent model capable of describing the structure and dynamics of the shocks and the time evolution of the pair-and gamma-ray distribution functions is developed and applied to gamma-ray flares in blazars, in the case in which gamma-ray production is dominated by inverse Compton scattering of external radiation (ERC). The dependence of the flare properties on magnetic field dissipation rate, intensity of ambient radiation, and the thickness of expelled fluid slabs is analyzed. It is shown that i) the type of gamma-ray flare produced by the model is determined by the ratio of the thickness of ejected fluid slab and the gradient length scale of ambient radiation intensity, ii) the radiative efficiency depends sensitively on the opacity contributed by the background radiation, owing to a radiative feedback, and is typically very high for parameters characteristic to the powerful blazars, and iii) the emitted flux is strongly suppressed at energies for which the pair-production optical depth is initially larger than unity; the time lag and flare duration in this energy range increase with increasing gamma-ray energy. At lower energies, flaring at different gamma-ray bands occurs roughly simultaneously, but with possibly different amplitudes. Some observational consequences are discussed.

Spatial features of reverberant speech: estimation and application to recognition and diarization
Creators: name: Peso, Pablo
Publisher: name: Imperial College London
Year: 2016

description: Distant talking scenarios, such as hands-free calling or teleconference meetings, are essential for natural and comfortable human-machine interaction and they are being increasingly used in multiple contexts. The acquired speech signal in such scenarios is reverberant and affected by additive noise. This signal distortion degrades the performance of speech recognition and diarization systems creating troublesome human-machine interactions.This thesis proposes a method to non-intrusively estimate room acoustic parameters, paying special attention to a room acoustic parameter highly correlated with speech recognition degradation: clarity index. In addition, a method to provide information regarding the estimation accuracy is proposed. An analysis of the phoneme recognition performance for multiple reverberant environments is presented, from which a confusability metric for each phoneme is derived. This confusability metric is then employed to improve reverberant speech recognition performance. Additionally, room acoustic parameters can as well be used in speech recognition to provide robustness against reverberation. A method to exploit clarity index estimates in order to perform reverberant speech recognition is introduced. Finally, room acoustic parameters can also be used to diarize reverberant speech. A room acoustic parameter is proposed to be used as an additional source of information for single-channel diarization purposes in reverberant environments. In multi-channel environments, the time delay of arrival is a feature commonly used to diarize the input speech, however the computation of this feature is affected by reverberation. A method is presented to model the time delay of arrival in a robust manner so that speaker diarization is more accurately performed.

description: We report the discovery with the Keck telescope of two new multiply-imaged arcs in the luminous X-ray cluster A2219 ($z=0.225$). The brighter arc in the field is red and we use spectroscopic and photometric information to identify it as a $z \sim 1$ moderately star-forming system. The brightness of this arc implies that it is formed from two merging images of the background source, and we identify possible candidates for the third image of this source. The second giant arc in this cluster is blue, and while fainter than the red arc it has a similarly large angular extent (32 arcsec). This arc comprises three images of a single nucleated source -- the relative parities of the three images are discernible in our best resolution images. The presence of several bright multiply imaged arcs in a single cluster allows detailed modelling of the cluster mass distribution, especially when redshift information is available. We present a lensing model of the cluster which explains the properties of the various arcs, and we contrast this model with the optical and X-ray information available on the cluster. We uncover significant differences between the distributions of mass and X-ray gas in the cluster. We suggest that such discrepancies may indicate an on-going merger event in the cluster core, possibly associated with a group around the second brightest cluster member. The preponderance of similar merger signatures in a large fraction of the moderate redshift clusters would indicate their dynamical immaturity.

Novel envelopment dynamics in bovine herpesvirus 1 assembly
Creators: name: Bleasdale, Ben
Publisher: name: Imperial College London
Year: 2014

description: Bovine herpesvirus-1 (BHV-1) is a member of the alphaherpesvirus subfamily which includes several prominent animal and human pathogens, including herpes simplex virus 1 (HSV-1). A new model for the morphogenesis of HSV-1 has recently been proposed, in which the virus is enveloped by endocytic membranes recently derived from the plasma membrane. Here we show that this model extends to a second alphaherpesvirus, BHV-1, through a detailed ultrastructural study of morphogenesis using electron microscopy and techniques which utilise the particularly high abundance of the protein VP8 in the BHV-1 tegument. These studies also revealed that greater than half of the particles released during BHV-1 infection are capsidless, non-infectious ‘light’ particles (L-particles). Such particles are composed of only tegument and an envelope, and display comparable protein profiles to virions. These L-particles were shown to be efficiently produced under conditions where DNA synthesis was inhibited, indicating that the processes of glycoprotein trafficking to the plasma membrane, retrieval into endocytic membranes, recruitment of tegument to these membranes, and the egress of these particles from the cell, all represent autonomous events which are ongoing from the early stages of infection. In short, we have demonstrated that BHV-1 infected cells can be viewed as efficient factories for the continuous and autonomous secretion of enveloped virus-like particles, irrespective of the availability of DNA for packaging. We propose BHV-1 as an excellent model for further investigation of both the process of tegumentation and the role of L-particles in virus infection.

description: Under the logistic regression framework, we propose a forward-backward method, SODA, for variable selection with both main and quadratic interaction terms. In the forward stage, SODA adds in predictors that have significant overall effects, whereas in the backward stage SODA removes unimportant terms to optimize the extended Bayesian information criterion (EBIC). Compared with existing methods for variable selection in quadratic discriminant analysis, SODA can deal with high-dimensional data in which the number of predictors is much larger than the sample size and does not require the joint normality assumption on predictors, leading to much enhanced robustness. We further extend SODA to conduct variable selection and model fitting for general index models. Compared with existing variable selection methods based on the sliced inverse regression (SIR), SODA requires neither linearity nor constant variance condition and is thus more robust. Our theoretical analysis establishes the variable-selection consistency of SODA under high-dimensional settings, and our simulation studies as well as real-data applications demonstrate superior performances of SODA in dealing with non-Gaussian design matrices in both logistic and general index models.

Regulation of virus induced inflammation by type I interferons
Creators: name: Goritzka, Michelle
Publisher: name: Imperial College London
Year: 2015

description: Type I interferons (IFNs) are the first line of defence against viral pathogens. They play a crucial role in activating antiviral responses to limit viral replication and viral spread. Human respiratory syncytial virus (RSV) can cause severe lung inflammation and this has been associated with polymorphisms in several innate immune response genes, including many that control the IFN system. In order to elucidate the importance of type I IFNs in regulating local inflammatory responses in the lung, their role in pulmonary immune responses to RSV infection was assessed in mice lacking the type I IFN receptor (Ifnar1-/-). Levels of proinflammatory cytokines and chemokines were markedly reduced during RSV infection. Similar results were obtained when in Ifnar1-/- mice were challenged with non-infectious innate stimuli such as Toll-like receptor agonists. It was further shown that the administration of recombinant IFN-α together with innate stimuli was sufficient to potentiate the proinflammatory cytokine production. Exploiting a reporter mouse strain expressing GFP under the control of the Ifna6 promoter, alveolar macrophages (AMs) were identified as the predominant source of type I IFNs during RSV infection. This type I IFN production solely relied on signalling through the cytosolic RIG-I-like receptors (RLRs), as AMs lacking MAVS, the adaptor downstream of RLRs, were unable to produce type I IFNs. Furthermore, Mavs-/- mice showed compromised production of proinflammatory cytokines and chemokines, and as a consequence had an increased viral burden and RSV-induced pathology. Interestingly, Mavs-/- mice had a marked deficiency in the production of monocyte chemoattractants and recruitment of inflammatory monocytes (infMo). The administration of recombinant CCL2 during RSV infection permitted monocyte recruitment into the lung of Mavs-/- mice and mediated an unexpected antiviral activity and reduced disease severity. This work emphasises a role for type I IFNs in antiviral immune responses by driving early proinflammatory cytokine responses and recruitment of antiviral monocytes, a yet underappreciated novel cell type responsible for dampening RSV-disease burden in vivo.
The Rapid Decay of the Optical Emission from GRB 980326 and its Possible Implications

description: We report the discovery of the optical counterpart to GRB 980326. Its rapid optical decay can be characterized by a power law with exponent -2.10 +/- 0.13 and a constant underlying source at R_c=25.5 +/- 0.5. Its optical colours 2.1 days after the burst imply a spectral slope of -0.66 +/- 0.70. The gamma-ray spectrum as observed with BATSE shows that it is among the 4% softest bursts ever recorded. We argue that the rapid optical decay may be a reason for the non-detection of some low-energy afterglows of GRBs.

Investigation of cold dwell facet fatigue in titanium alloys utilising crystal plasticity and discrete dislocation plasticity modelling techniques
Creators: name: Zheng, Zebang
Publisher: name: Imperial College London
Year: 2016

description: The focus of this project is the mechanistic basis of the load shedding phenomenon that occurs under the dwell fatigue loading scenario. A systematic study was carried out using modelling techniques at different length scales, from atomistic simulations to discrete dislocation plasticity and crystal plasticity, to investigate the effect of crystallographic orientations, localized dislocation behaviour, material intrinsic properties and external loading environments on the dwell sensitivity. A new mechanistic formalism for incorporating thermally activated dislocation escape into discrete dislocation plasticity modelling techniques is presented. The origin of the rate-sensitive behaviour of plasticity over strain rate regimes from 〖10〗^(-5) to 〖10〗^5 s^(-1) has been assessed with reference to three key mechanisms: dislocation nucleation, time of flight (dislocation mobility) and thermally activated escape of pinned dislocations. It is shown that nucleation and dislocation mobility explain rate-sensitive behaviour for strain rates in the range 〖10〗^2 to 〖10〗^5 s^(-1) while thermally-activated dislocation escape becomes the predominant rate-controlling mechanism at low strain rates. The new thermal activation DDP model was then use to investigate the soft-hard-soft rogue grain combination which is commonly associated with load shedding in Ti-6Al, Ti-6242 and Ti-6246 alloys. The application of Stroh’s dislocation pile-up model of crack nucleation to facet fracture was quantitatively assessed. Crystal plasticity modelling has been utilised to extract the thermal activation energies for pinned dislocation escape for Ti alloys based on independent experimental data. The activation energies determined are then utilised within the polycrystalline DDP model to predict the load shedding in the aforementioned alloys. The grain morphology and grain boundary penetrability effect were also studied but the key property controlling the load shedding is argued to be the time constant of the thermal activation process relative to that of the loading. The dwell sensitivity of Ti alloys was also found to be highly related to the temperature. The load shedding was found to diminish at very low or very high temperatures and maximum peak stress increase occurs at a higher temperature for a material with high activation energy. The deformation mechanisms under dwell fatigue loading are categorised into three scenarios and discussed separately.

description: The nearby barred spiral galaxy NGC 1313 has been observed with the PSPC instr- ument on board the ROSAT X-ray satellite. Ten individual sources are found. Three sources (X-1, X-2 and X-3 [SN~1978K]) are very bright (~10^40 erg/s) and are unusual in that analogous objects do not exist in our Galaxy. We present an X-ray image of NGC~1313 and \xray spectra for the three bright sources. The emission from the nuclear region (R ~< 2 kpc) is dominated by source X-1, which is located ~1 kpc north of the photometric (and dynamical) center of NGC~1313. Optical, far-infrared and radio images do not indicate the presence of an active galactic nucleus at that position; however, the compact nature of the \xray source (X-1) suggests that it is an accretion-powered object with central mass M >~ 10^3 Msun. Additional emission (L_X ~ 10^39 erg/s) in the nuclear region extends out to ~2.6 kpc and roughly follows the spiral arms. This emission is from 4 sources with luminosity of several x 10^38 erg/s, two of which are consistent with emission from population I sources (e.g., supernova remnants, and hot interstellar gas which has been heated by supernova remnants). The other two sources could be emission from population II sources (e.g., low-mass \xray binaries). The bright sources X-2 and SN~1978K are positioned in the southern disk of NGC~1313. X-2 is variable and has no optical counterpart brighter than 20.8 mag (V-band). It is likely that it is an accretion-powered object in NGC~1313. The type-II supernova SN~1978K (Ryder \etal 1993) has become extra- ordinarily luminous in X-rays $\sim$13 years after optical maximum.

description: In the treatment of patients with atrial fibrillation (AF) who undergo percutaneous coronary intervention (PCI), it is unclear which combination of antithrombotic drugs is preferable and which is the optimal duration of treatment. The authors review the available evidence in this area resulting from single studies and meta-analyses. In the absence of direct head-to-head comparisons between different non-vitamin K oral anticoagulants (NOAC), the authors review the available studies with NOACS in these patients and derived indirect comparisons. In patients with AF who undergo PCI, a dual antithrombotic strategy which includes a NOAC plus single antiplatelet therapy with a P2Y12 inhibitor (preferably clopidogrel) should be considered as the preferred treatment option in most cases. Oral anticoagulation associated with dual antiplatelet therapy (triple antithrombotic therapy) should be offered for no longer than 30 days to patients with very high thrombotic and low hemorrhagic risk. It is unclear whether the dual antithrombotic strategy should be continued beyond 12 months in patients at high risk of thrombotic events. Additional data from adequately powered controlled studies are needed to support the long-term efficacy of this strategy and to establish the best patient-tailored approach in this complex scenario.

Statistics of dark matter haloes expected from weak lensing surveys

description: The distortion of the images of faint high-redshift galaxies can be used to probe the intervening mass distribution. This weak gravitational lensing effect has been used recently to study the (projected) mass distribution of several clusters at intermediate and high redshifts. In addition, the weak lensing effect can be employed to detect (dark) matter concentrations in the Universe, based on their mass properties alone. Thus it is feasible to obtain a mass-selected sample of `clusters', and thereby probe the full range of their mass-to-light ratios. We study the expected number density of such haloes which can be detected in ongoing and future deep wide-field imaging surveys, using the number density of haloes as predicted by the Press-Schechter theory, and modeling their mass profile by the `universal' density profile found by Navarro, Frenk & White. We find that in all cosmological models considered, the number density of haloes with a signal-to-noise ratio larger than 5 exceeds 10 per square degree. With the planned MEGACAM imaging survey of $\sim 25 deg^2$, it will be easily possible to distinguish between the most commonly discussed cosmological parameter sets.

description: In the current work, a new highly selective and sensitive sensor based on PVC membrane for accurate trace detection of chromium (III) ions as the environmental contaminant based on 4-Isopropylcalix[4]arene (4-IPC4) was developed. The electrode demonstrated a working range from 1.0 × 10−6 to 1.0 × 10−1 M with 19.45 ± 0.21 mV and 9.0 × 10−7 M of Nernstian slope and detection limit, respectively. The pH of the electrode was independent of the potential response over the range of 3.0 to 5.5. The developed sensor revealed acceptable repeatability for at least three months with fast response time (less than 15 seconds). The impedance changes of the solution/electrode interface were investigated using the EIS technique. The proposed sensor was used successfully for direct detection of Chromium (III) ions in biological and environmental samples and the obtained values validated by AAS and ICP techniques with the recovery values varied from 99.6 to 101.9% for the concentration range of 15.0 to 75.0 ppm. Moreover, the electrode was successfully applied as an indicator electrode for potentiometric titration of Cr3+ cation with standard EDTA solution. The characterisation of the proposed sensor and its selective membrane were carried out using FT-IR, UV-Vis, and SEM techniques. The adsorption energy as an important parameter of trapping has been calculated at B3LYP/3-21G (d) level via using the density functional theory (DFT). The strong interactions were resulted by natural bond orbital (NBO) calculations between lone pair of O with lone pair* of chromium (III) ions which revealed that the charge transfer plays important role in the formation of the complex.

description: Projectors are a simple but powerful tool for manipulating and probing quantum systems. For instance, projecting two-qubit systems onto maximally entangled states can enable quantum teleportation. While such projectors have been extensively studied, partially-entangling measurements have been largely overlooked, especially experimentally, despite their important role in quantum foundations and quantum information. Here, we propose a way to project two polarized photons onto any state with a single experimental setup. Our scheme does not require optical non-linearities or additional photons. Instead, the entangling operation is provided by Hong-Ou-Mandel interference and post-selection. The efficiency of the scheme is between 50% and 100%, depending on the projector. We perform an experimental demonstration and reconstruct the operator describing our measurement using detector tomography. Finally, we flip the usual role of measurement and state in Hardy's test by performing a partially-entangling projector on separable states. The results verify the entangling nature of our measurement with six standard deviations of confidence.

description: Phytochemical investigation the resins of Ferula sinkiangensis K.M.Shen yielded three new tetrahydrobenzofuran derivatives named as Sinkiangensis A-C (1–3). The structures of the new compounds were elucidated by analysis of their NMR, HRMS, and ECD spectra, and the absolute configurations were established through the comparison of experimental and calculated ECD spectra. Compound 3 exhibited moderate antitumor activities against AGS cancer cell with IC50 values of 15.6 µM. Moreover, assays demonstrated that compound 3 could induce AGS cancer cell apoptosis.

description: The geometry of the ${\cal N} = 3$, SO(4)--invariant, AdS$_4$ solution of massive type IIA supergravity that uplifts from the ${\cal N} = 3 $ vacuum of $D=4$ ${\cal N} = 8$ dyonic ISO(7) supergravity is investigated. Firstly, a $D=4$, SO(4)--invariant restricted duality hierarchy is constructed and used to uplift the entire, dynamical SO(4)--invariant sector to massive type IIA. The resulting consistent uplift formulae are used to obtain a new local expression for the ${\cal N} = 3 $ AdS$_4$ solution in massive IIA and analyse its geometry. Locally, the internal $S^6$ geometry corresponds to a warped fibration of $S^2$ and a hemisphere of $S^4$. This can be regarded as a warped generalisation of the usual twistor fibration geometry. Finally, the triplet of Killing spinors corresponding to the ${\cal N}=3$ solution are constructed and shown to obey the massive type IIA Killing spinor equations.

description: We compare the burst distribution of the new (2B) BATSE catalogue to a cosmological distribution. The observed distribution agrees well with a cosmological one, however, it is insensitive to cosmological parameters such as $Ø$ and $Λ$. The bursts are not necessarily standard candles and their luminosity can vary by up to a factor of ten. The maximal red shift, $\zm$, of bursts longer than 2 sec is $2.1^{+1.}_{-.7}$ (assuming no evolution). The present data is insufficient to determine maximal red shift, $\zm$, of bursts shorter than 2 sec.
