Structural behaviour of laser-welded stainless steel I-sections
Creators: name: Bu, Yidu
Publisher: name: Imperial College London
Year: 2017

description: Stainless steel structures have been increasingly used in engineering applications because of its corrosion resistance, aesthetic appeal, favourable structural properties as well as the development of stainless steel guidance. While the structural response of cold-formed stainless steel sections has been extensively studied in the literature, welded sections have received less attention to date. A recent addition to the range of structural stainless steel products is that of laser-welded sections. Owing to the high precision and low heat input of the fabrication process, the resulting sections have smaller heat affected zones, lower thermal distortions and lower residual stresses than would typically arise from traditional welding processes. There currently exists very limited experimental data on laser-welded stainless steel members owing to their recent introduction to the construction industry and their design is not covered by current design standards. To address the lack of test data and to investigate their structural response, a comprehensive experimental programme has been carried out covering complementary residual stress measurements, 9 stub column tests, 20 bending tests and 24 combined loading tests at the cross-sectional level, as well as 22 flexural buckling tests and 18 beam-columns at the member level. The derived test results were then employed in the numerical studies where the numerical models were first validated against the test results and then used to conduct a series of parametric studies to generate further data over a wider range of cross-sectional slendernesses, member slendernesses and loading combinations. The test and numerical results were used to assess the current design provisions and it was found that the design codes yield conservative predictions due to the neglect of strain hardening. Revised design rules have been proposed, offering less scattered, more accurate predictions for conventionally welded members and, for the first time, design provisions for laser-welded members.
Advanced fluidised bed gasification for carbon capture and fuel cell applications
Creators: name: Long, Xiangyi
Publisher: name: Imperial College London
Year: 2017

description: The rapid global economic and population growth requires consistent supply of energy. Gasification is a promising technology for processing solid fuels. One of the technology options is the integration of coal gasification with combined cycle (IGCC). As concerns over enhanced global warming have increased, more advanced technology such as integration of IGCC system with carbon capture and storage (CCS) has been proposed, such as oxyfuel IGCC. Another technology for power generation that can be used instead of IGCC is integrated gasification fuel cell (IGFC). IGFC can also be combined with oxyfuel concept to mitigate global warming. The main objectives of this work are to obtain a greater understanding of oxyfuel gasification of coal and to assess the impact of gases produced on typical materials used in fuel cells. A laboratory scale continuous pressurised fluidised bed reactor has been modified to study CO2 and steam (concentration up to 40%mol.) gasification of coal at 850 °C and pressures up to 10 bara. A second stage fixed bed reactor has been specially designed and constructed to study degradation of different solid oxide fuel cell (SOFC) anode materials (nickel/yttrium stabilised zirconium oxide (Ni/YSZ) and nickel/gadolinium-doped ceria (Ni/CGO)) after exposure to real fuel gas at 765 °C. The main findings include: (1) C conversion decreased significantly at high pressure. This drop was mainly caused by the char deactivation through repolymerisation of the volatiles. (2) Input steam increased C conversion, as steam was more reactive than CO2. However, moisture from feedstock behaved differently compared to steam addition in the gasification gas. (3) Ni/CGO showed a better performance than Ni/YSZ in terms of carbon and sulphur deposition. Fuel gas from CO2/H2O gasification tended to form less carbon and sulphur on tested anode materials than that from CO2 gasification.

description: Four high-latitude slow variable stars have been noted by Meinunger (1972) as "nicht rote" ("not red") objects and thus curious. We have previously reported (Margon & Deutsch 1997) that one of these objects, CC Boo, is in fact a QSO. Here we present observations demonstrating that the remaining three are also highly variable active galactic nuclei. The most interesting object of the four is perhaps S 10765 (= NGP9 F324-0276706), which proves to be a resolved galaxy at z=0.063. Despite the rapid and large reported variability amplitude (~1.6 mag), the spectrum is that of a perfectly normal galaxy, with no emission lines or evident nonthermal continuum. We also present new spectroscopic and photometric observations for AR CVn, suggested by Meinunger to be an RR Lyrae star despite its very faint magnitude (=19.4). The object is indeed one of the most distant RR Lyrae stars known, at a galactocentric distance of ~40 kpc.

description: A wide class of inflationary models, known as Hybrid Inflation models, may produce topological defects during a phase transition at the end of the inflationary epoch. We point out that, if the energy scale of these defects is close to that of Grand Unification, then their effect on cosmic structure formation and the generation of microwave background anisotropies cannot be ignored. Therefore, it is possible for structure to be seeded by a combination of the adiabatic perturbations produced during inflation and active isocurvature perturbations produced by defects. Since the two mechanisms are uncorrelated the power spectra can be computed by a weighted average of the individual contributions. We investigate the possible observational consequences of this with reference to general Hybrid Inflation models and also a specific model based on Supergravity. These mixed perturbation scenarios have some novel observational consequences and these are discussed qualitatively.

description: Software documentation often struggles to catch up with the pace of software evolution. The lack of correct, complete, and up-to-date documentation results in an increasing number of documentation defects which could introduce delays in integrating software systems. In our previous study on a bug analysis tool called MultiDimEr, we provided evidence that documentation-related defects contribute to many bug reports. First, we want to identify documentation defect types contributing to documentation defects, thereby identifying documentation debt. Secondly, we aim to find pragmatic solutions to minimize most common documentation defects to pay off the documentation debt in the long run. We investigated documentation defects related to an industrial software system. First, we looked at different documentation types and associated bug reports. We categorized the defects according to an existing documentation defect taxonomy. Based on a sample of 101 defects, we found that most defects are caused by documentation defects falling into the Information Content (What) category (86). Within this category, the documentation defect types Erroneous code examples (23), Missing documentation (35), and Outdated content (19) contributed to most of the documentation defects. We propose to adapt two solutions to mitigate these types of documentation defects. In practice, documentation debt can easily go undetected since a large share of resources and focus is dedicated to delivering high-quality software. We suggest adapting two main solutions to tackle documentation debt by implementing (i) Dynamic Documentation Generation (DDG) and/or (ii) Automated Documentation Testing (ADT), which are both based on defining a single and robust information source for documentation.

description: We present a statistical study of chromospheric evaporation in solar flares using simultaneous observations by the RHESSI X-ray telescope and the IRIS UV spectrograph. The results are compared with radiation hydrodynamic flare models from the F-CHROMA RADYN database. For each event, we study spatially-resolved Doppler shifts of spectral lines formed in the transition region (C\,II\,1334.5\,Å) and hot coronal plasma (Fe\,XXI\,1354.1\,Å) to investigate the dynamics of the solar atmosphere during the flare impulsive phase. We estimate the energy fluxes deposited by high-energy electrons using X-ray imaging spectroscopy and assuming the standard thick-target model. Using the RADYN flare models, the RH 1.5D radiative transfer code and the Chianti atomic line database, we calculate C\,II and Fe\,XXI line profiles and compare with the observations. While the RADYN models predict a correlation between the Doppler shifts and deposited energy flux for both lines, this was only observed in the C II data. Several quantitative discrepancies are found between the observations and models: the Fe\,XXI Doppler shifts are substantially stronger in the models than in the data; the C\,II mean blueshifts are absent in the observations but predicted by the models. The transition energy between `gentle' and `explosive' evaporation regimes estimated from the observations ($2-8\times{}10^{9}$~erg~cm$^{-2}$~s$^{-1}$) and derived from the models ($2.2-10.1\times{}10^{9}$~erg~cm$^{-2}$~s$^{-1}$) are comparable with each other. The results illustrate relationships among the processes of chromospheric evaporation, response of the colder layers, and the flare energy flux deposited by high-energy electrons, although demonstrating discrepancy between analyzed observations and RADYN models.

description: Background: Systematic literature studies (SLS) have become a core research methodology in Evidence-based Software Engineering (EBSE). Search completeness, ie, finding all relevant papers on the topic of interest, has been recognized as one of the most commonly discussed validity issues of SLSs. Aim: This study aims at raising awareness on the issues related to search string construction and on search validation using a quasi-gold standard (QGS). Furthermore, we aim at providing guidelines for search string validation. Method: We use a recently completed tertiary study as a case and complement our findings with the observations from other researchers studying and advancing EBSE. Results: We found that the issue of assessing QGS quality has not seen much attention in the literature, and the validation of automated searches in SLSs could be improved. Hence, we propose to extend the current search validation approach by the additional analysis step of the automated search validation results and provide recommendations for the QGS construction. Conclusion: In this paper, we report on new issues which could affect search completeness in SLSs. Furthermore, the proposed guideline and recommendations could help researchers implement a more reliable search strategy in their SLSs.

description: Incompatibility of observables, or measurements, is one of the key features of quantum mechanics, related, among other concepts, to Heisenberg's uncertainty relations and Bell nonlocality. In this manuscript we show, however, that even though incompatible measurements are necessary for the violation of any Bell inequality, some relevant Bell-like inequalities may be obtained if compatibility relations are assumed between the local measurements of one (or more) of the parties. Hence, compatibility of measurements is not necessarily a drawback and may, however, be useful for the detection of Bell nonlocality and device-independent certification of entanglement.

description: We present a new model for the gas dynamics in the galactic disk inside the Sun's orbit. Quasi-equilibrium flow solutions are determined in the gravitational potential of the deprojected COBE NIR bar and disk, complemented by a central cusp and, in some models, an outer halo. These models generically lead to four-armed spiral structure between corotation of the bar and the solar circle; their large-scale morphology is not sensitive to the precise value of the bar's pattern speed, to the orientation of the bar with respect to the observer, and to whether or not the spiral arms carry mass. Our best model provides a coherent interpretation of many observed gas dynamical features. Its four-armed spiral structure outside corotation reproduces quantitatively the directions to the five main spiral arm tangents at |l|<=60deg observed in a variety of tracers. The 3-kpc-arm is identified with one of the model arms emanating from the ends of the bar, extending into the corotation region. The model features an inner gas disk with a cusped orbit shock transition to an x_2 orbit disk of radius R~150pc. The bar's corotation radius is fairly well--constrained at R_c=3.5 +/- 0.5 kpc. The best value for the orientation angle of the bar is probably 20-25deg, but the uncertainty is large since no detailed quantitative fit to all features in the observed lv-diagrams is yet possible. The Galactic terminal velocity curve from HI and CO observations out to l=+/-45deg (=5 kpc) is approximately described by a maximal disk model with constant mass-to-light ratio for the NIR bulge and disk.

description: The characterization of quantum processes, e.g. communication channels, is an essential ingredient for establishing quantum information systems. For quantum key distribution protocols, the amount of overall noise in the channel determines the rate at which secret bits are distributed between authorized partners. In particular, tomographic protocols allow for the full reconstruction, and thus characterization, of the channel. Here, we perform quantum process tomography of high-dimensional quantum communication channels with dimensions ranging from 2 to 5. We can thus explicitly demonstrate the effect of an eavesdropper performing an optimal cloning attack or an intercept-resend attack during a quantum cryptographic protocol. Moreover, our study shows that quantum process tomography enables a more detailed understanding of the channel conditions compared to a coarse-grained measure, such as quantum bit error rates. This full characterization technique allows us to optimize the performance of quantum key distribution under asymmetric experimental conditions, which is particularly useful when considering high-dimensional encoding schemes.

description: The close X-ray selected BL Lac PKS 2155-304 has been observed using the University of Durham Mark 6 very high energy (VHE) gamma ray telescope during 1996 September/October/November and 1997 October/November. VHE gamma rays with energy > 300 GeV were detected from this object with a time-averaged integral flux of (4.2 +/- 0.7 (stat) +/- 2.0 (sys)) x 10^(-11) per cm2 per s. There is evidence for VHE gamma ray emission during our observations in 1996 September and 1997 October/November, with the strongest emission being detected in 1997 November, when the object was producing the largest flux ever recorded in high-energy X-rays and was detected in > 100 MeV gamma-rays. The VHE and X-ray fluxes show evidence of a correlation.

description: Principal component analysis (PCA) is widely used for feature extraction and dimensionality reduction, with documented merits in diverse tasks involving high-dimensional data. Standard PCA copes with one dataset at a time, but it is challenged when it comes to analyzing multiple datasets jointly. In certain data science settings however, one is often interested in extracting the most discriminative information from one dataset of particular interest (a.k.a. target data) relative to the other(s) (a.k.a. background data). To this end, this paper puts forth a novel approach, termed discriminative (d) PCA, for such discriminative analytics of multiple datasets. Under certain conditions, dPCA is proved to be least-squares optimal in recovering the component vector unique to the target data relative to background data. To account for nonlinear data correlations, (linear) dPCA models for one or multiple background datasets are generalized through kernel-based learning. Interestingly, all dPCA variants admit an analytical solution obtainable with a single (generalized) eigenvalue decomposition. Finally, corroborating dimensionality reduction tests using both synthetic and real datasets are provided to validate the effectiveness of the proposed methods.

description: Over the last several decades, Bangladesh has experienced rapid economic growth, which has been largely fueled by a robust RMG sector that now represents 85% of the value of the nation's exports. Nearly 3.5 million people were employed by the sector, and it gave rise to a huge number of secondary, industrial, and export-driven sectors. Because of the nation's over reliance on RMG, exports have also become dangerously imbalanced and need to be significantly diversified in order to maintain the economic development thus far. The Bangladeshi leather and leather goods industry is one of the sectors the government sees strong potential. It is one of the oldest industries in Bangladesh. Bangladesh's leather sector exports 10% of the world's leather demand, and has overtaken RMG as the nation's second-largest source of foreign currency. Bangladesh has 2% of the world's livestock due to its favorable environment for the care and growing of animals. Bangladeshi leather is well-known around the world for its superior fine grain, consistent fiber structure, smooth feel, and organic texture. The leather industry in Bangladesh is currently developing the capacity to manufacture processed raw leather and leather goods in environmentally friendly methods.
Computer vision and machine learning for in-play tennis analysis: framework, algorithms and implementation

Publisher: name: Imperial College London
Year: 2018

description: Statistical analysis has become an essential part of professional sports to the point that every major professional team employs expert analysts. With the widespread availability of high definition streaming data, increased processing power and algorithmic advances, statistical models are undergoing an evolution from static coarse-grained pre-play models based on simple statistical data to finer-grained dynamic in-play models that exploit spatio-temporal data and event streams. Our primary hypothesis is that Computer Vision (CV) and Machine Learning (ML) research has opened up the opportunity to develop automated systems to collect the fine-grained data needed to support these more sophisticated models. We have chosen tennis as our focus on account of it being a highly structured sport which has enthusiastically embraced technology, but our research is also applicable to other sports. In this work, we propose a novel framework for the application of CV and ML techniques to the in-play spatio-temporal analysis of tennis using commodity hardware with the ultimate objective of obtaining insights related to players’ performance or prediction of future events. Our framework consists of three-layers: Vision, Classification and Modelling, each of which features various algorithmic innovations. For the Vision Layer we propose a multi-camera system able to detect the player and ball positions in real-time, at over 60 fps. Their 3D inferred location has an error lower than 10 cm in 80% of the frames. The Classification Layer uses data from the previous layer to obtain high- level information. Our contributions within this layer are two-fold: (1) insightful visualizations of Vision Layer data and automatic extraction of high-level statistics (2) the first deep Neural Network for fine-grained action recognition in tennis which yields highly competitive results: 88.16% one versus all accuracy for classifying backhands, forehands and serves and 47.22% in classifying 12 finer-grained actions. The Modelling Layer incorporates the data obtained for the previous two layers to gain insights about the game. For this layer, we survey and critically examine different approaches of using tennis spatio-temporal data for prediction and analysis. Our work opens the door to a deeper understanding of tennis and other sports leading to new approaches to coaching, better analysis of rivals for developing strategies and in-play match analysis to enhance spectators’ experience, amongst many other applications.

description: Over the recent years, the introduction of high-throughput technologies, such as Next-Generation Sequencing, has allowed the discovery of new microRNA isoforms (isomiRs), along with the canonical ones, that could be different in length, sequence, or both and could have a supportive or antagonist role beside database-annotated molecules.

Mir-125a-5p has been commonly considered a tumor suppressor microRNA whose expression is downregulated in several cancers. However, the in-depth study of miR-125a-5p isoforms, through the small RNA-seq analysis of TCGA samples, showed a general upregulation of the canonical miR-125a-5p in most cancer tissues and a near-total downregulation of the isoforms miR-125a-5p (0|-2) and (0|-3).

Poly(A)-specific RNase (PARN) is a 3’-5’ exonuclease responsible for the digestion of the 3’ end of many microRNAs. We demonstrated that PARN trims the genome-encoded 3' extension of miR-125a-5p, producing the isoforms miR-125a-5p (0|-2) and (0|-3), and thereby stabilizes the molecule through the removal of the untemplated poly(A)tail.

Moreover, we demonstrated that the upregulation of the two shorter isoforms (0|-2) and (0|-3) results in the downregulation of some cell cycle key proteins, such as Cyclin E2 (CCNE2), Cyclin-dependent kinase 2 (CDK2), and Cyclin-dependent kinase 6 (CDK6) in breast cancer cells, suggesting that only these isoforms of miR-125a-5p play a role of tumor suppressor microRNA in cancer.

description: A One-Dimensional (1D) Reduced-Order Model (ROM) has been developed for a 3D Rayleigh-Bénard convection system in the turbulent regime with Rayleigh number $\mathrm{Ra}=10^6$. The state vector of the 1D ROM is horizontally averaged temperature. Using the Green's Function (GRF) method, which involves applying many localized, weak forcings to the system one at a time and calculating the responses using long-time averaged Direct Numerical Simulations (DNS), the system's Linear Response Function (LRF) has been computed. Another matrix, called the Eddy Flux Matrix (EFM), that relates changes in the divergence of vertical eddy heat fluxes to changes in the state vector, has also been calculated. Using various tests, it is shown that the LRF and EFM can accurately predict the time-mean responses of temperature and eddy heat flux to external forcings, and that the LRF can well predict the forcing needed to change the mean flow in a specified way (inverse problem). The non-normality of the LRF is discussed and its eigen/singular vectors are compared with the leading Proper Orthogonal Decomposition (POD) modes of the DNS data. Furthermore, it is shown that if the LRF and EFM are simply scaled by the square-root of Rayleigh number, they perform equally well for flows at other $\mathrm{Ra}$, at least in the investigated range of $ 5 \times 10^5 \le \mathrm{Ra} \le 1.25 \times 10^6$. The GRF method can be applied to develop 1D or 3D ROMs for any turbulent flow, and the calculated LRF and EFM can help with better analyzing and controlling the nonlinear system.

description: We derive power density spectra in the optical and X-ray band in the timescale range from several years down to $\sim $ a day. We suggest that the optical power density spectrum consists of two separate components: long timescale variations and short timescale variations, with the dividing timescale around 100 days. The shape of the short timescale component is similar to X-ray power density spectrum which is consistent with the interpretation of short timescale optical variations being caused by X-ray reprocessing. We show that the observed optical long timescale variability is consistent with thermal pulsations of the accretion disc.

description: Ebola virus disease causes widespread and highly fatal epidemics in human populations. During the latest outbreak in West Africa only 60% of the affected people underwent diagnosis, emphasising the unmet need for suitable diagnostics tools. This thesis harnesses the intrinsic optical properties of nanoparticles for the development of two nanoparticles-based biosensing systems for the detection of Ebola virus. The first system is a serological point-of-care test for humoral immune response to Ebola virus. This test combines in-house made capture ligands, lateral flow technology with a custom smartphone application. The final format of the test replicates all mechanical, optical and electronic functions of a laboratory-based enzyme-linked immunosobent assay in a single and multiple analytes formats. This assay was evaluated validated in Uganda using sera from nearly 130 Sudan Ebola Virus survivors and controls, demonstrating 96% sensitivity and 100% specificity. In addition to the single analyte format, two configurations of the multiple analyte formats were constructed. The first configuration simultaneously detected the immune response to three viral antigens. In the second configuration, the point-of-care test was translated for Bundibugyo Ebola Virus species and used for the identification of immune cross reactivity between viral species. The second system was targeted for earlier stage viral detection via direct detection of fragments of viral nucleic acids. This assay comprised spherical nucleic acids nanoparticles as the biosensing interface and Exonuclease III for target recycling amplification. Although the system is operated in a laboratory, it was addressed to function with the simplest form of laborious equipment to enable its used in resource-limited facilities. These complementary systems have to potential to be utilised for patient management, surveillance during and post outbreaks and vaccine and therapeutic evaluation.

description: In this paper we present a data analysis regarding globular clusters as possible extragalactic distance indicators. For this purpose, we collected all velocity dispersion measurements published for galactic and M31 globular clusters. The slope and the zero-point of the Faber-Jackson relation were calibrated using Hipparcos distance measurements, and the relation was applied to extragalactic globular clusters in M31. A distance modulus of 24.12 \pm 0.45 mag was found. This is coherent with what is found by fitting the red giant branches of globular clusters (24.47 \pm 0.07, Holland 98), and is found from the peak of globular clusters luminosity function (24.03 \pm 0.23, Ostriker an d Gnedin 97), but shorter than the 24.7 \pm 0.2 mag (Lanoix et al. 98) and 24.77 \pm 0.11 mag (Feast and Catchpole 97), obtained by using Hipparcos data to calibrate the Cepheid period-luminosity. This calibrated Faber-Jackson relation can now be directly use for other Sc galaxies with resolved globular clusters, as soon as large amounts of spectra will become available, e.g., through the VLT.

description: Heavy-ion collisions are well described by a dynamical evolution with a long hydrodynamical phase. In this phase the properties of the strongly coupled quark-gluon plasma are reflected in the equation of state (EoS) and the transport coefficients, most prominently by the shear and bulk viscosity over entropy density ratios $η$/s(T) and $ζ$/s(T), respectively. While the EoS is by now known to a high accuracy, the transport coefficients and in particular their temperature and density dependence are not well known from first-principle computations yet, as well as the possible influence they can have once used in hydrodynamical simulations. In this work, the most recent QCD-based parameters are provided as input to the MUSIC framework. A ratio $η$/s(T) computed with a QCD based approach is used for the first time \cite{Haas:2013hpa,Christiansen:2014ypa}. The IP-Glasma model is used to describe the initial energy density distribution, and UrQMD for the dilute hadronic phase. Simulations are performed for Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV, for different centrality intervals. The resulting kinematic distributions of the particles produced in the collisions are compared to data from the LHC, for several experimental observables. The high precision of the experimental results and the broad variety of observables considered allow to critically verify the quality of the description based on first-principle input to the hydrodynamic evolution.

description: As engineered systems expand, become more interdependent, and operate in real-time, reliability assessment is indispensable to support investment and decision making. However, network reliability problems are known to be #P-complete, a computational complexity class largely believed to be intractable. The computational intractability of network reliability motivates our quest for reliable approximations. Based on their theoretical foundations, available methods can be grouped as follows: (i) exact or bounds, (ii) guarantee-less sampling, and (iii) probably approximately correct (PAC). Group (i) is well regarded due to its useful byproducts, but it does not scale in practice. Group (ii) scales well and verifies desirable properties, such as the bounded relative error, but it lacks error guarantees. Group (iii) is of great interest when precision and scalability are required, as it harbors computationally feasible approximation schemes with PAC-guarantees. We give a comprehensive review of classical methods before introducing modern techniques and our developments. We introduce K-RelNet, an extended counting-based estimation method that delivers PAC-guarantees for the K-terminal reliability problem. Then, we test methods' performance using various benchmark systems. We highlight the range of application of algorithms and provide the foundation for future resilience engineering as it increasingly necessitates methods for uncertainty quantification in complex systems.

description: Reactive flow control has been shown as a promising tool to improve, among other aspects, the aerodynamic characteristics of an aircraft. This paper focuses on the use of reactive flow control to attenuate Tollmien-Schlichting (TS) waves over a wing profile. TS waves are an instability mechanism that is one of the first stages of boundary layer transition to turbulence. The Wiener-Hopf technique was used in this work for the experimental boundary layer control. The approach improves previous wave-cancellation techniques that, by constructing control kernels in the frequency domain, lead to control kernels with a non-causal part, i.e., actuation would need future sensor information to be constructed. In practical applications, it is unfeasible to access this type of information. Ignoring the non-causal part of the kernel leads to suboptimal solutions that might significantly degrade the performance of the controller. The Wiener-Hopf formalism allows us to take into account causality constraints in the formulation of the control problem, leading to an optimal realistic solution and a control kernel that is causal by construction. Moreover, it is possible to construct the control strategy based only on the power and cross-spectra obtained experimentally, in a data-driven approach. The present work shows how to apply experimentally the Wiener-Hopf resolvent-based formalism using signals from a wind tunnel experiment, demonstrating that the Tollmien-Schlichting waves can be effectively attenuated via a Wiener-Hopf based controller, which yielded better results than a typical wave-cancellation approach.
