Distribution network optimisation for an active network management system
Creators: name: Ahmadi, Ali Reza
Publisher: name: Imperial College London
Year: 2011

description: The connection of Distributed Generators (DGs) to a distribution network causes technical concerns for Distribution Network Operators (DNOs) which include power flow management, loss increase and voltage management problems. An Active Network Management System can provide monitoring and control of the distribution network as well as providing the infrastructure and technology for full integration of DGs into the distribution network. The Optimal Power Flow (OPF) method is a valuable tool in providing optimal control solutions for active network management system applications. The research presented here has concentrated on the development of a multi-objective OPF to provide power flow management, voltage control solutions and network optimisation strategies. The OPF has been shown to provide accurate solutions for variety of network topologies. It is possible to apply time-series of load and generation data to the OPF in a loop, generating optimal network solutions to maintain the network within thermal and voltage limits. The OPF incorporates not only the DG real power output maximisation, but also network loss minimisation as well as minimising the dispatch of DG reactive power. This investigation uses a direct Interior Point (IP) method as the solution methodology which is speed efficient and converges in polynomial time. Each objective function has been assigned a weighting factor, making it possible to favour one objective function and ignore the others. Contributions to enhance the performance of the IP OPF algorithm include a new generic barrier parameter formulation and a new swing bus formulation to model energy export/import in the main optimisation routine. A Terminal Voltage Regulator Mode (TVRM) and Power Factor Regulation Mode (PFRM) for DG were incorporated in the main optimisation routine. The main motivation is to compare these two decentralised DG control methods in terms of the achieving the maximum DG real power generation. The DG operation methods of TVRM and PFRM are compared with the optimisation results obtained from centralised dispatch in terms of the DG capacity achieved as it produces the optimum overall network solution. A suitable value of the droop and local voltage regulator dead-bands were determined for particular DGs. Furthermore, the effect of these decentralised DG control methods on distribution network losses are considered in a measure to assess the financial implications from a DNO's perspective.

description: We propose a method for in-situ measurement of the length of kilometer size Fabry-Perot cavities in laser gravitational wave detectors. The method is based on the vernier, which occurs naturally when the laser incident on the cavity has a sideband. By changing the length of the cavity over several wavelengths we obtain a set of carrier resonances alternating with sideband resonances. From the measurement of the separation between the carrier and a sideband resonance we determine the length of the cavity. We apply the technique to the measurement of the length of a Fabry-Perot cavity in the Caltech 40m Interferometer and discuss the accuracy of the technique.

Human embryonic stem cell-derived cardiomyocytes as a novel in vitro cardiac model system
Creators: name: Mioulane, Maxime
Publisher: name: Imperial College London
Year: 2011

description: Objectives: Human embryonic stem cell-derived cardiomyocytes (hESC-CM) are investigated as a source of cardiac cells for cell therapy and as a novel model for drug screening. In this thesis, we asked whether hESC-CM can serve as a valuable system for testing compounds in toxicological screens and we undertook a characterization of their contraction properties with regards to their phenotypic variability. Methods: Contraction was measured using edge detection microscopy (Ionoptix) on clusters of hESC-CM and in paced isolated hESC-CM or other isolated ventricular cardiomyocytes. Cell death assay was performed in adherent isolated cardiomyocytes. hESC-CM were stained with fluorescent markers of apoptosis and necrosis and scanned using automated fluorescence microscopy (Cellomics). Results: Clusters of hESC-CM underwent maturation as seen by the change in their basal beating rate with time of culture and the negative chronotropic effect of adenosine. The development of the chronotropic response to adenosine was heterogenous during the intermediate stage and correlated with the effect of Carbarchol, suggesting the emergence of distinct cardiomyocyte subtypes. Adenosine mediated its effect through the activation of A1 Adenosine receptor and positive inotropic effect in isolated hESC-CM possibly through A2a, as in human failing cardiomyocytes. Apoptosis and necrosis could be detected and quantified specifically in hESC-CM as well as in neonates, allowing further direct inter-species comparison in high content screening approach. hESC-CM and neonates differed in term of sensitivity to apoptosis in response to Chelerythrine and to β-adrenergic stimulation. The pro and anti-apoptotic effects of different immuno-suppressive drugs were evaluated in hESC-CM as a prerequisite for future transplantation. Conclusion: hESC-CM can serve as an alternative cardiomyocyte model for investigating the effect of compounds on contraction and toxicity. Our study points out the developmental stage and possibly the differentiation method as a source of phenotypic heterogeneity. Consequently, the differentiation protocols needs to be standardized and in vitro maturation need to be improved. Also, we showed that the modulation of cell death in hESC-CM might greatly differ from current cardiomyocytes models used for toxicity screens.
Prediction of Acoustic Resonances in Core Volumes
Creators: name: De Montgros, Armel
Publisher: name: Imperial College London
Year: 2011

description: In numerous industrial systems, acoustic resonances are synonymous with loud noise and dramatic structural vibrations. They take their origin from trapped weak pressure waves, but can sometimes develop into complex instabilities. With specific emphasis on turbomachines applications, two computational methods have been developed for the prediction of acoustic resonances in core volumes. The first method, called the averaged response function, consists of combined time-domain and frequency-domain approaches. A Favre-averaged RANS solver is used to model the response of a system to a controlled chirp excitation. The response is then analysed using well-known modal analysis tools in order to extract the system’s acoustic characteristics. The second method, called the Arnoldi method, focuses on the stability of the CFD solver. The system is transformed, using a linear Euler solver, into a classic matrix stability problem. The eigenpairs of the matrix, corresponding to the acoustic modeshapes of the system, are then extracted thanks to the iterative Arnoldi method. The two methods are validated and compared on a wide range of cases such as enclosures, open geometries and flow applications. Such a thorough study first provides the reader with a deeper insight into acoustic phenomena by considering classic acoustic examples such as the end correction concept, the Doppler effect and the ”lock-in“ phenomenon. This study also investigates the limitations and qualities of the implemented methods which are seen to behave very well when compared to theory and experiments. They give accurate results in predicting the three components of the acoustic resonance: the frequency, the damping and the modeshape. As a result, the methods implemented are considered to be mature and can be used to study either the complete acoustic map of the system across a wide range of frequencies or specific acoustic instabilities in a narrow frequency range.

description: In this note we develop the theory of the quantum Pontryagin principle for continuous measurements and feedback. The analysis is carried out under the assumption of compatible events in the output channel. The plant is a quantum system, which generally is in a mixed state, coupled to a continuous measurement channel. The Pontryagin Maximum Principle is derived in both the Schrödinger picture and Heisenberg picture, in particular in statistical moment coordinates. To avoid solving stochastic equations we derive a LQG scheme which is more suitable for control purposes.

Protein citrullination by Porphyromonas gingivalis and its implications for autoimmunity in rheumatoid arthritis
Creators: name: Wegner, Natalia
Publisher: name: Imperial College London
Year: 2011

description: Autoantibodies to citrullinated proteins are characteristic for rheumatoid arthritis (RA). RA has been associated with periodontitis in epidemiologic studies. Chronic periodontal infection with Porphyromonas gingivalis (P. gingivalis) is a possible risk factor for developing RA, as this bacterium expresses a peptidylarginine deiminase enzyme (PPAD) which could generate antigenic citrullinated proteins within an infectious context. The aim of this project was to investigate protein citrullination by P. gingivalis and its potential for breaking tolerance to citrullinated proteins in RA. Endogenous citrullinated proteins were abundant in cell extracts of P. gingivalis but lacking in other tested oral bacteria. Deletion of the PPAD gene resulted in abrogation of protein citrullination. Inactivation of arginine-gingipains but not lysine-gingipains, the major proteolytic virulence factors, led to decreased citrullination. Incubation of wildtype P. gingivalis with fibrinogen or α-enolase caused degradation of the proteins by bacterial proteinases and peptidases and citrullination of the resulting peptides at carboxy-terminal arginine residues. No statistically significant antibody reactivity was found in RA serum with two of these peptides tested. The PPAD enzyme was cloned and expressed in E. coli in an enzymatically active form and used for in vitro enzymatic assays to confirm substrate specificity for carboxy-terminal arginine residues and demonstrate inhibition by 2- chloroacetamidine, but not by conventional RA drugs. Site-directed mutagenesis identified five amino acids crucial for catalysis. A polyclonal antibody was developed and demonstrated that PPAD is localised in the bacterial outer membrane. The results demonstrate that P. gingivalis generates citrullinated endogenous and host peptides by proteolytic cleavage at arginine-X peptide bonds by arginine-gingipains followed by citrullination of carboxy-terminal arginines by PPAD. Mutagenesis and inhibition studies point to a critical cysteine (Cys-351) in the catalytic centre. The work provides the basis for future studies of the role of PPAD in bacterial virulence and tolerance breakdown in RA.

description: Quality factor plays a fundamental role in dynamic mode atomic force microscopy. We present a technique to modify the quality factor of an atomic force microscopy cantilever within a Fabry-Pérot optical interferometer. The experimental setup uses two separate laser sources to detect and excite the oscillation of the cantilever. While the intensity modulation of the excitation laser drives the oscillation of the cantilever, the average intensity can be used to modify the quality factor via optomechanical force, without changing the fiber-cantilever cavity length. The technique enables users to optimize the quality factor for different types of measurements without influencing the deflection measurement sensitivity. An unexpected frequency shift was also observed and modelled as temperature dependence of the cantilever's Young's modulus, which was validated using finite element simulation. The model was used to compensate for the thermal frequency shift. The simulation provided relations between optical power, temperature, and frequency shift.

Inelastic Behaviour of Hybrid Steel/Concrete Column-to-Flat Slab Assemblages
Creators: name: Eder, Martin A.
Publisher: name: Imperial College London
Year: 2011

description: The use of tubular columns in conjunction with reinforced concrete flat slabs provides structurally efficient solutions which avoid undesirable failure modes such as those associated with shear. This thesis is concerned with the development of a tubular column-to- flat slab connection system that enables reliable performance under seismic loading conditions. During this research a novel detail which features a gap around the column is proposed and developed; hence only the structural steel shearhead establishes the connection. The exposed parts of the shear arms (fuses) are designed to yield prior to punching shear failure, in a way that utilises the favourable features of steel in terms of the response to seismically induced loads. The proposed connection could serve as a primary lateral resisting system within all building configurations in regions of low to moderate seismicity or as a secondary system in areas of signi cant seismicity. In order to provide validation for the proposed details as well as associated numerical and design procedures, a purpose-built rig which is suitable for large scale testing of structural sub assemblages under combined gravity and uniaxial lateral loading, has been designed and constructed, and subsequently employed for a number of tests. Test results and numerical analyses are presented with respect to a conventional con guration, as well as for the proposed, partially embedded connection. The latter is shown to offer enhanced ductility compared with traditional forms. The results are used to demonstrate the favourable inelastic performance of the proposed detail in terms of ductility, low degradation effects and increased energy dissipation capabilities. Complementary small scale slab panel tests are also used to further optimise the composite behaviour of the proposed detail. Additionally, a closed form solution based on plastic limit analysis which can serve as a basis for a simplified design approach is proposed. Finally, the main findings from the experimental and analytical investigations are highlighted, and recommendations for future research are outlined.

description: Orientation-dependent reactivity and band-bending are evidenced upon Ti deposition (1-10 Å) on the polar ZnO(0001)-Zn and ZnO(000$\bar{1}$)-O surfaces. At the onset of the Ti deposition, a downward band-bending was observed on ZnO(000$\bar{1}$)-O while no change occurred on ZnO(0001)-Zn. Combining this with the photoemission analysis of the Ti 2p core level and Zn L$_3$(L$_2$)M$_{45}$M$_{45}$ Auger transition, it is established that the Ti/ZnO reaction is of the form Ti + 2 ZnO $\rightarrow$ TiO$_2$ + 2 Zn on ZnO(0001)-Zn and Ti + y ZnO $\rightarrow$ TiZn$_x$O$_y$ + (y-x) Zn on ZnO(000$\bar{1}$)-O. Consistently, upon annealing thicker Ti adlayers, the metallic zinc is removed to leave ZnO(0001)-Zn surfaces covered with TiO$_2$-like phase and ZnO(000$\bar{1}$)-O surfaces covered with a defined (Ti, Zn, O) compound. Finally, a difference in the activation temperature between the O-terminated (500 K) and Zn-terminated (700 K) surfaces is observed, which is tentatively explained by different electric fields in the space charge layer at ZnO surfaces.

Interplay between polycomb repression and RNA polymerase II regulation genome-wide in murine ES cells
Creators: name: Domingos De Jesus, Ines De Santiago
Publisher: name: Imperial College London
Year: 2011

description: Gene regulation is a complex process that involves recruitment of transcription machinery, chromatin modification, and co-transcriptional RNA processing. RNA polymerase II (RNAPII) transcribes protein-coding genes. It contains a carboxy- terminal domain (CTD) consisting of multiple repeats. Specific patterns of CTD modifications promote the recruitment of appropriate factors at different stages of the transcription cycle, integrating transcription with chromatin modification and co-transcriptional RNA processing. In pluripotent ES cells, Polycomb repressive complexes (PRCs) silence important developmental regulator genes. I have investigated RNAPII regulation at PRC-target genes genome-wide in murine ES cells by mining ChIP-Seq and mRNA-Seq datasets, using computational approaches. PRC targets exhibit different expression and RNAPII states: Silent genes lacking RNAPII, silent genes associated with RNAPII which is phosphorylated on the serine 5 residue of the CTD (S5P) but lacking serine 2 phosphorylated residues (S2P), and expressed genes with both S5P and S2P. At silent PRC-target genes, S5P and PRCs co-occupy the same promoters and the complexes extend into coding regions in the absence of S2P, suggesting disruption of co-transcriptional RNA processing. Sequential ChIP demonstrates simultaneous association of PRC and RNAPII to the same chromatin. Most expressed PRC-target genes display CTD marks of activity, including presence of S2P throughout the gene body; however S2P and PRCs do not co-immunoprecipitate, suggesting that active and PRC-repression are two separate chromatin states, that occur in different cells of the ES population, or within different alleles in the same cell. Finally, I have developed a software, SeqGI, for the analysis and interpretation of sequencing data. SeqGI provides a GUI framework for the simultaneous visualisation and statistical evaluation of read profiles over genomic features. This work provides valuable insights on the biology of ES cells, and elucidates combinations of different factors across the genome shedding light on different mechanisms of gene activation, poising and silencing.

Interaction between the fundamental torsional guided wave mode and complex defects in pipes
Creators: name: Carandente, Rosalba
Publisher: name: Imperial College London
Year: 2011

description: The presence of defects in pipelines is a concern especially in petrochemical applications where the service integrity of pipes is a fundamental requirement to avoid process interruptions and to fulfil safety standards. Guided wave inspection is now routinely used in industry for screening long lengths of pipe for corrosion, any suspect areas then being followed up with conventional ultrasonic thickness gauging. However, this is difficult in cases where the suspect area is inaccessible (e.g. buried pipelines or pipes passing though walls), so it would be very useful to apply guided wave techniques for sizing as well as the detection and location of defects. This target is challenging due to the complexity of the profiles encountered in practice. The present work aims to improve the understanding of the scattering of the fundamental torsional mode T(0, 1) from complex shaped discontinuities and to determine the controlling parameters of this phenomenon. The overall analysis starts with a study of the reflection from axi-symmetric tapered steps and notches in pipes. After that the scattering from three dimensional (3D) defects with different shapes has been studied. Firstly, flat-bottomed defects with different surface profiles have been analyzed, and then the study of the reflection behavior from 3D defects with varying depth profile has been carried out. All of the work presented here uses the T(0,1) mode for inspection. It is revealed that the reflection coefficient maxima from axi-symmetric tapered defects decrease with increasing frequency as the slope of the taper becomes more gradual, this effect being more pronounced when the ratio of the average defect length to the wavelength increases. Tapered defects are therefore expected to be more difficult to detect at higher inspection frequencies; this effect is more evident for shallower tapers. It is also found that at a given maximum depth of a finite discontinuity, the peak of the reflection coefficient from a defect is linearly dependent on the circumferential extent of the defect, and is independent of its shape. The results from these analyses have been used to propose a practical approach to determine the maximum depth of a complex discontinuity from the reflection coefficient behavior, provided that the external circumferential extent of the defect is known. This method has been applied to real corrosion patches and the results validated with experiments. Its main limitation is on defects with a gradual corrosion section profile, but with a sudden change of the depth over a small circumferential region. It is shown then that a possible way to diagnose sharp circumferential profile changes is to measure the reflection coefficient spectrum at frequency higher than usually used in long range guided wave inspection.

description: Security analyses of quantum cryptographic protocols typically rely on certain conditions; one such condition is that the sender (Alice) and receiver (Bob) have isolated devices inaccessible to third parties. If an eavesdropper (Eve) has a side-channel into one of the devices, then the key rate may be sensibly reduced. In this paper, we consider an attack on a coherent-state protocol, where Eve not only taps the main communication channel but also hacks Alice's device. This is done by introducing a Trojan horse mode with low mean number of photons $\bar{n}$ which is then modulated in a similar way to the signal state. First we show that this strategy can be reduced to an attack without side channels but with higher loss and noise in the main channel. Then we show how the key rate rapidly deteriorates for increasing photons $\bar{n}$, being halved at long distances each time $\bar{n}+1$ doubles. Our work suggests that Alice's device should also be equipped with sensing systems that are able to detect and estimate the total number of incoming and outgoing photons.

description: Construction of a five dimensional conformal supergravity (D=5 CSG) is attempted by applying the AdS/CFT correspondence to the F(4) AdS supergravity in six dimensions. As a first step, local transformation laws of D=5 CSG have been established, from which the Weyl weights of the various fields in D=5 can be predicted.

The Kazhdan-Lusztig conjecture for W-algebras

description: The main result in this paper is the character formula for arbitrary irreducible highest weight modules of W algebras. The key ingredient is the functor provided by quantum Hamiltonian reduction, that constructs the W algebras from affine Kac-Moody algebras and in a similar fashion W modules from KM modules. Assuming certain properties of this functor, the W characters are subsequently derived from the Kazhdan-Lusztig conjecture for KM algebras. The result can be formulated in terms of a double coset of the Weyl group of the KM algebra: the Hasse diagrams give the embedding diagrams of the Verma modules and the Kazhdan-Lusztig polynomials give the multiplicities in the characters.

Cellular responses of murine epiphyseal cartilage to mechanical injury
Creators: name: Chong, Ka-Wing
Publisher: name: Imperial College London

description: Our laboratory has defined a rapid cellular response in porcine articular cartilage to injury. To enable study of the injury response in genetically modified animals I have characterized a novel model of cartilage injury in the mouse, involving avulsion of femoral head epiphyseal cartilage from 4-6 week old animals, and maintaining the explanted tissue in culture. Avulsion injury (explantation) of murine cartilage rapidly activated mitogen activated protein kinases (MAPKs) and nuclear factor κB (NFκB), thus establishing a close similarity to porcine tissue. Gene expression (mRNA) was analysed on Taqman® Low density array microfluidic cards for 47 pre-selected genes. 25 were upregulated upon injury; many characteristic of the inflammatory response. Some were upregulated early (by 1 h) and some not till after 4 h, suggesting primary and secondary responses. Re-cutting cartilage adapted to culture only activated a subset of genes, probably due to release of fibroblast growth factor 2 (FGF2) which is stored pericellularly. Gene expression profiling of explanted cartilage of Fgf2-deficient mice showed 7 of the 25 (28%) genes were partly or largely FGF2-dependent. Because the gene and signalling profiles resembled an inflammatory response I examined tissue deficient in the myeloid differentiation 88 protein (MyD88) an adaptor protein for signalling of the interleukin-1 receptor and toll-like receptor family. 12 of the 25 genes were MyD88-dependent. MyD88-/- cartilage did not show impairment of the intracellular signalling response upon injury and expression of a MyD88-dependent gene (Ccl2) did not increase till 4 h of culture. It was likely that a MyD88-using ligand was made during the primary response and contributed to the secondary. I conclude there are at least 3 mechanisms by which cartilage injury activates gene expression: 1) release of pericellular FGF2, 2) an unkown trigger of MAPK and NFκB and 3) secondary production of a MyD88-using factor.

description: One of the fundamental properties of a salient object region is its contrast with the immediate context. The problem is that numerous object regions exist which potentially can all be salient. One way to prevent an exhaustive search over all object regions is by using object proposal algorithms. These return a limited set of regions which are most likely to contain an object. Several saliency estimation methods have used object proposals. However, they focus on the saliency of the proposal only, and the importance of its immediate context has not been evaluated. In this paper, we aim to improve salient object detection. Therefore, we extend object proposal methods with context proposals, which allow to incorporate the immediate context in the saliency computation. We propose several saliency features which are computed from the context proposals. In the experiments, we evaluate five object proposal methods for the task of saliency segmentation, and find that Multiscale Combinatorial Grouping outperforms the others. Furthermore, experiments show that the proposed context features improve performance, and that our method matches results on the FT datasets and obtains competitive results on three other datasets (PASCAL-S, MSRA-B and ECSSD).
