title: Common ground: horticulture and the cultivation of open space in the East End of London, 1840-1900
Creators: name: Matheson, Julia
Publisher: name: The Open University
Year: 2010

description: This thesis re-examines the characterisation of the East End of London as an area associated with poverty and urban degradation. It uses a wide range of sources to show that there was more open space and a greater interest in horticulture within the population than has hitherto been recognised. Local newspapers, gardening journals and maps have been used to demonstrate that among East Enders were both amateur and professional gardeners. Amateurs gardened in backyards and window boxes, but horticultural expert Shirley Hibberd compared their flower shows favourably with those of the Royal Horticultural Society. There was a wide range of nurserymen and market gardeners supplying local individuals and the London markets. These industries have not featured in any discussion of East End employment. There were also open spaces which served many functions for the district. Victoria Park, the largest landscaped open space in the East End, provided both an example of horticultural excellence and also a site for recreation; cemeteries, in their early days, had ambitions to provide pleasantly landscaped surroundings in which mourners could find peace, though these ambitions did not survive the pressure of numerous burials; the small parks and gardens provided by the Metropolitan Public Gardens Association were an example of what could be achieved by the efforts of philanthropists who were anxious to help the poor at the end of the century. This thesis argues that gardening should be recognised in historical debate as a pastime that was popular with all classes, not just the elite. It also suggests that most studies of the East End have underestimated the presence and importance of open space even in such an overcrowded and poverty-stricken area.

description: One of the main concerns in the design of bridge structures is evaluating the resistance capacity of foundation settings. Full-scale reinforced concrete piles are commonly used as a traditional method in the design of deep foundations; however, the use of micropiles as an alternative method can facilitate the process of the bridge construction by addressing the concerns such as different properties of the soil layers and site restrictions. The objective is to introduce an alternative solution in that the geometry of the construction area, such as limited overhead access areas, or the existed structures in the adjacent of the project would not affect the efficiency of deep foundations. In this regard, the battered (inclined) piles are applicable based on the geometry criteria. Moreover, applying micropiles is a preferred method in soil remedial practices along with the maintenance procedure of existing foundations. This study deals with the effect of applying micropiles on soil stabilization by enhancing the bearing capacity of the existing soil layers. Variations in soil properties using 9 drilled boreholes before and after implementation of micropiles are addressed. The results of the standard penetration test (SPT) prior to and after the installation of micropiles prove the considerable effect of micropiles on enhancing the soil properties.

description: We report a detailed study of the ground state helical magnetic structure in monophosphide FeP by means of ${}^{31}$P NMR spectroscopy. We show that the zero-field NMR spectrum of the polycrystalline sample provides strong evidence of an anisotropic distribution of local magnetic fields at the P site with substantially lower anharmonicity than that found at the Fe site by Mössbauer spectroscopy. From field-sweep ${}^{31}$P NMR spectra we conclude that a continuous spin-reorientation transition occurs in an external magnetic field range of 4 - 7 T, which is also confirmed by specific-heat measurements. We observe two pairs of magnetically inequivalent phosphorus positions resulting in a pronounced four-peak structure of the single crystal ${}^{31}$P NMR spectra characteristic of an incommensurate helimagnetic ground state. We revealed a spatial redistribution of local fields at the P sites caused by Fe spin-reorientation transition in high fields and developed an effective approach to account for it. We demonstrate that all observed ${}^{31}$P spectra can be treated within a model of an isotropic helix of Fe magnetic moments in the ($ab$)-plane with a phase shift of 36$^{\circ}$ and 176$^{\circ}$ between Fe1-Fe3 (Fe2-Fe4) and Fe1-Fe2 (Fe3-Fe4) sites, respectively, in accordance with the neutron scattering data.

description: This study examines the effects of FDI (foreign direct investment) on export performance for a single country Pakistan, using 30 years data from a period 1981 to 2010. The ordinary least square estimation results indicate significant positive effect of terms of trade on economic growth. Furthermore, volatility of terms of trade has significant positive effect on economic growth. To test the robustness of initial results, sensitivity analysis has been performed using different additional variables, sample size and various proxies of volatility variable. The initial results were found robust despite the inclusion of various variables in the basic model and use of various proxies for volatility of terms of trade.

description: Electric vehicle (EV) supply equipment location and allocation (EVSELCA) problems for freight vehicles are becoming more important because of the trending electrification shift. Some previous works address EV charger location and vehicle routing problems simultaneously by generating vehicle routes from scratch. Although such routes can be efficient, introducing new routes may violate practical constraints, such as drive schedules, and satisfying electrification requirements can require dramatically altering existing routes. To address the challenges in the prevailing adoption scheme, we approach the problem from a fixed-route perspective. We develop a mixed-integer linear program, a clustering approach, and a metaheuristic solution method using a genetic algorithm (GA) to solve the EVSELCA problem. The clustering approach simplifies the problem by grouping customers into clusters, while the GA generates solutions that are shown to be nearly optimal for small problem cases. A case study examines how charger costs, energy costs, the value of time (VOT), and battery capacity impact the cost of the EVSELCA. Charger equipment costs were found to be the most significant component in the objective function, leading to a substantial reduction in cost when decreased. VOT costs exhibited a significant decrease with rising energy costs. An increase in VOT resulted in a notable rise in the number of fast chargers. Longer EV ranges decrease total costs up to a certain point, beyond which the decrease in total costs is negligible.

description: The ongoing process of eco-friendly consumption makes consumers increasingly sensitive to quality of the purchased food. Their high demands are met by traditional products whose high quality stems from special ingredients and methods of preparation.The aim of this article is to determine the consumers reviews towards safe solutions for food production. On the background of polish and foreign literature relating to purchasing habits of consumers on the food market, the identification of factors determining choice of products was made and it was verified to what extent this choice is affected by processing methods and food preservation. The paper uses findings from a survey of 272 inhabitants of Podkarpackie province. Studies have shown that consumers have little knowledge about methods of processing and food preservation. Along with the increase of education it can be noted, however, a growth in preference of qualitative characteristics of products in a buying process. / Synopsis.

description: Dependency parsing (DP) is a task that analyzes text for syntactic structure and relationship between words. DP is widely used to improve natural language processing (NLP) applications in many languages such as English. Previous works on DP are generally applicable to formally written languages. However, they do not apply to informal languages such as the ones used in social networks. Therefore, DP has to be researched and explored with such social network data. In this paper, we explore and identify a DP model that is suitable for Thai social network data. After that, we will identify the appropriate linguistic unit as an input. The result showed that, the transition based model called, improve Elkared dependency parser outperform the others at UAS of 81.42%.

description: Spatially resolved images of the galactic supernova remnant G78.2+2.1 (gamma-Cygni) in hard X-ray energy bands from 25 keV to 120 keV are obtained with the IBIS-ISGRI imager aboard the International Gamma-Ray Astrophysics Laboratory INTEGRAL. The images are dominated by localized clumps of about ten arcmin in size. The flux of the most prominent North-Western (NW) clump is (1.7 +/- 0.4) 10^{-11} erg/cm^2/s in the 25-40 keV band. The observed X-ray fluxes are in agreement with extrapolations of soft X-ray imaging observations of gamma-Cygni by ASCA GIS and spatially unresolved RXTE PCA data. The positions of the hard X-ray clumps correlate with bright patches of optical line emission, possibly indicating the presence of radiative shock waves in a shocked cloud. The observed spatial structure and spectra are consistent with model predictions of hard X-ray emission from nonthermal electrons accelerated by a radiative shock in a supernova interacting with an interstellar cloud, but the powerful stellar wind of the O9V star HD 193322 is a plausible candidate for the NW source as well.

description: Regime switching is ubiquitous in many complex dynamical systems with multiscale features, chaotic behavior, and extreme events. In this paper, a causation entropy boosting (CEBoosting) strategy is developed to facilitate the detection of regime switching and the discovery of the dynamics associated with the new regime via online model identification. The causation entropy, which can be efficiently calculated, provides a logic value of each candidate function in a pre-determined library. The reversal of one or a few such causation entropy indicators associated with the model calibrated for the current regime implies the detection of regime switching. Despite the short length of each batch formed by the sequential data, the accumulated value of causation entropy corresponding to a sequence of data batches leads to a robust indicator. With the detected rectification of the model structure, the subsequent parameter estimation becomes a quadratic optimization problem, which is solved using closed analytic formulae. Using the Lorenz 96 model, it is shown that the causation entropy indicator can be efficiently calculated, and the method applies to moderately large dimensional systems. The CEBoosting algorithm is also adaptive to the situation with partial observations. It is shown via a stochastic parameterized model that the CEBoosting strategy can be combined with data assimilation to identify regime switching triggered by the unobserved latent processes. In addition, the CEBoosting method is applied to a nonlinear paradigm model for topographic mean flow interaction, demonstrating the online detection of regime switching in the presence of strong intermittency and extreme events.

description: A recent market basket survey of organophosphate insecticides in Trinidad clearly indicated improper use of this class of insecticides on produce offered for sale to local consumers. In several cases, crops appeared to have been harvested without regard for recommended pre-harvest intervals, as well as being treated shortly before harvest. On many samples, recommended maximum residue levels were exceeded, particularly on celery, on which mixtures of insecticides were frequently and consistently detected. Supervised field trials of five of the most commonly detected organophosphates showed that recommended pre-harvest intervals of each pesticide were often not in accordance with actual field degradation rates. In some cases, residue levels of pesticides declined faster than expected, raising the possibility of re-infestation of crops by pests within the recommended pre-harvest intervals. Our results indicate a pressing need for supervised efficacy and pesticide residue trials, of all pesticides used on food crops under local growing and storage conditions, and offered for sale locally or exported. The recent acceptance of HACCP for food production systems also mandates regular monitoring of edible crops for contaminants, including pesticide residues, to ensure the safety of consumers.

description: A systematic zig-zag design was implemented at three anthurium shade-houses during 1992 - 1993 for monthly sampling of plant - parasitic nematodes. Radopholus similis was shown to be the predominant nematode associated with the crop. Paratylenclus minutus was the only other potential plant - parasitic nematode identified. Population densities of R. similis exhibited annual fluctuations with maximum levels observed between August and September at the three locations. The population densities of nematodes varied widely with locations but the composition of females, males, and juveniles within the populations was similar. Various fungi were isolated from root lesions. Stunting, chlorosis, and root rotting were commonly associated with nematode infested plants.

description: We present a readout method for superconducting flux qubits. The qubit quantum flux state can be measured by determining the Josephson inductance of an inductively coupled DC superconducting quantum interference device (DC-SQUID). We determine the response function of the DC-SQUID and its back-action on the qubit during measurement. Due to driving, the qubit energy relaxation rate depends on the spectral density of the measurement circuit noise at sum and difference frequencies of the qubit Larmor frequency and SQUID driving frequency. The qubit dephasing rate is proportional to the spectral density of circuit noise at the SQUID driving frequency. These features of the backaction are qualitatively different from the case when the SQUID is used in the usual switching mode. For a particular type of readout circuit with feasible parameters we find that single shot readout of a superconducting flux qubit is possible.

title: The Hinkley Point 'C' public inquiry and the privatisation of the UK electricity supply industry : dislocations in power relationships in the civil nuclear power policy sector
Creators: name: Roberts, Susan Jane
Publisher: name: The Open University
Year: 1991

description: A detailed empirical case study of the motivations of the major objecting group participants at the Hinkley Point "C" Public Inquiry is set in the context of an analysis of the transitions caused to the UK nuclear power policy sector by the privatisation of the ESI. First, historical comparative analysis of the nuclear power policy sectors of the USA, Canada, France and the FRG shows a positive correlation between corporatism and successful implementation of policy, and this is borne out by the case of the UK. It is concluded that a fully developed corporatist policy sector, its authority unchallenged by other systems of representation, will usually be a necessary condition for a successful nuclear programme. The failure to privatise the CEGB nuclear power stations is accounted for in terms of a model of the conflicting aims of the privatisation of monopolistic industries. Second, analysis of interview data gathered during Hinkley "C" Inquiry with major group participants is used, in the context of the model of the policy sector developed earlier, to account for the apparent discrepancy between the allocation of resources by opposition groups to the Hinkley "C" Inquiry and their meagre expectations of rewards from the formal, internal Inquiry processes. It is concluded that: 1. Although groups claimed to be pursuing strategies that were external to the Inquiry process, the nature of the Inquiry limited the success of this approach. 2. The representatives of groups interviewed displayed ambivalence, simultaneously believing participation was worthwhile and that the Inquiry was a sham. 3. Groups' most successful tactic was that of delay through mass objection and participation. The sensitivity of policy implementation to the institutional structure of the policy sector will be of considerable importance to the Government review of the prospects for nuclear power in 1994.

description: Liquefaction is a hazardous seismic-based phenomenon, which causes an abrupt decrease in soil strength properties and can result in the massive destruction of the built environment. This research presents a novel approach to reduce the risk of soil liquefaction using jet-grouted micropiles in clean sands. The saturated soil profile of the study project mainly contains clean sands, which are suitable to more reliably employ simplified soil liquefaction analyses. The grouting is conducted using 420 micropiles to increase the existing soil properties. The effect of jet grouting on reducing the potential of liquefaction is assessed using the results of the cone penetration test (CPT) and the standard penetration test (SPT), which were conducted before and after jet grouting by implementing micropiles in the project sites. According to three CPT-based liquefaction analyses, the Juang method predicts the most effective improvement range of the factor of safety in the clean sand. The Boulanger and Idriss, and Eurocode methods show comparable evaluations. Results of the SPT-based analyses show the most considerable increase of the factor of safety following the Boulanger and Idriss, and NCEER approaches in the SP soil. CPT- and SPT-based analyses confirm the effectiveness of jet grouting by micropiles on enhancing soil properties and reducing the risk of liquefaction.
Altering magnetic response of superconductors by rotation

Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: It is generally believed that, at a certain temperature below the critical one, magnetic response of a superconductor (SC) is determined solely by its intrinsic properties. Here we show that the mechanical rotation of a SC can easily change the values of the critical fields at which the superconductivity is destroyed (type-1 SC) or the vortices penetrate into (exit from) the material (type-2 SC). This is due to a superposition of the Meissner current induced by the external field, and the spontaneous current on the surface of the SC induced by the mechanical rotation. As a result, the critical fields of a SC can be increased or decreased, depending on the geometrical form of the material and the relative orientation of rotation and the external field.

description: Persistent interception of a Dipteran larva in shipments of hot pepper (Capsicum chinense) from Jamaica to the United States of America (USA) in recent years, has led to the imposition of mandatory fumigation of the commodity prior to export. The insect has been identified both as Contarinia lycopersici, a tomato pest of quarantine importance to the USA and Prodiplosis longifilia a citrus pest restricted in that country to Florida. The present study compares the pepper midges in Jamaica with C. lycopersici and P. longifilia based on morphological characteristics and host infestation. Preliminary results derived from comparative morphological examination of adult males, suggest that the pepper gall midges of Jamaica are distinguishable from C. lycopersici and P. longifilia. There is an urgent need to identify and or describe the species present in order to develop a management strategy for the pest.

description: We investigate self-moving particles which prefer to hop with a certain turning angle equally distributed to the right or left. We assume this turning angle distribution to be given by a double Gaussian distribution. Based on the model of Active Brownian particles and we calculate the diffusion coefficient in dependence on the mean and the dispersion of the turning angles. It is shown that bounded distribution of food in patches will be optimally consumed by the objects if they hop preferably with a given angle and not straight forwardly.

description: As an effective theory, relativistic hydrodynamics is fixed by symmetries up to a set of transport coefficients. A lot of effort has been devoted to explicit calculations of these coefficients. Here we propose a shift in perspective: we deploy bootstrap techniques to rule out theories that are inconsistent with microscopic causality. What remains is a universal convex geometry in the space of transport coefficients, which we call the hydrohedron. The landscape of all consistent theories necessarily lie inside or on the edges of the hydrohedron. We analytically construct cross-sections of the hydrohedron corresponding to bounds on transport coefficients that appear in sound and diffusion modes for theories without stochastic fluctuations.

description: Amitus hesperidum Silvestri (Hymenoptera: Platygasteridae) was introduced to Trinidad in 2000 in an attempt at classical biological control of the Citrus Blackfly Aleurocanthus woglumi Ashby (Homoptera: Aleyrodidae). Following quarantine, A. hesperidum were reared in the field in sleeve cages for multiplication and subsequent distribution. Fifty-three sleeve cages were established at six locations in Trinidad, however efforts were concentrated at the Todd's Road Citrus Estate of Caroni (1975) Limited. These sleeves resulted in a yield of 372 insects/sleeve with peak emergence at 56-66 days after the initial release of parasitoids. These results were used to guide the establishment of a further 35 sleeve cages for the production of parasitoids. One hundred participating farmers were trained in the biological control of Citrus Blackfly and provided with batches of 100 parasitoids for release on their farms.

description: Topological phases of matter have recently attracted a rather notable attention in the community dealing with the holographic methods applied to strongly interacting condensed matter systems. In particular, holographic models for gapless Weyl and multi-Weyl semimetals, characterized on a lattice by the monopole-antimonopole defects of the Berry curvature in momentum space, were recently formulated. In this paper, motivated by the quest for finding topological holographic phases, we show that holographic model for multi-Weyl semimetals features a rather rich landscape of phases. In particular, it includes a novel phase which we dub $xy$ nematic, stable at strong coupling, as we explicitly show by the free energy and the quasi-normal mode analyses. Furthermore, we provide its characterization through the anomalous transport coefficients. We hope that our findings will motivate future works exploring the holographic realizations of the topological phases.

description: Amitus hesperidum- a natural enemy of citrus blackfly (CBF) was imported into Trinidad in April 2000 and releases began in June 2000 in commercial citrus fields. An island wide survey was conducted in February 2001 to determine the distribution of Amitus, 8 months after initial releases. Leaf samples were collected from 100 farms across six counties. Counts of pupae with parasite exit holes, pupae with CBF exit holes and unhatched pupae were recorded. Leaves were also incubated in an insectary for emergence of adult Amitus. On a county basis average parasitism of 34%, 31%, 27%, 25%, 16% and 9% occurred in counties St. Patrick, Caroni, St. George, Victoria, St. Andrew/St.David and Nariva/Mayaro respectively. On a farm basis parasitism levels of 87 %(Penal) and 100% (Flanagin Town, Tableland) were observed at release and non-release sites respectively. Amitus adults were recovered at 32 farms of which, 14 were Amitus release sites, while 18 farms were non-release sites. Ratios of unhatched pupae to emerged Amitus adults as high as 1:3 were observed at both release and non-release sites in counties St. George and St. Patrick respectively. The average distance between nonrelease sites and the closest release site was 4.41cm.

description: Focusing on gains & losses relative to a risk-free benchmark instead of terminal wealth, we consider an asset allocation problem to maximize time-consistently a mean-risk reward function with a general risk measure which is i) law-invariant, ii) cash- or shift-invariant, and iii) positively homogeneous, and possibly plugged into a general function. Examples include (relative) Value at Risk, coherent risk measures, variance, and generalized deviation risk measures. We model the market via a generalized version of the multi-dimensional Black-Scholes model using $α$-stable Lévy processes and give supplementary results for the classical Black-Scholes model. The optimal solution to this problem is a Nash subgame equilibrium given by the solution of an extended Hamilton-Jacobi-Bellman equation. Moreover, we show that the optimal solution is deterministic under appropriate assumptions.

title: Improved methods for pattern discovery in music, with applications in automated stylistic composition
Creators: name: Collins, Thomas Edward
Publisher: name: The Open University
Year: 2011

description: Computational methods for intra-opus pattern discovery (discovering repeated patterns within a piece of music) and stylistic composition (composing in the style of another composer or period) can offer insights into how human listeners and composers undertake such activities. Two studies are reported that demonstrate improved computational methods for pattern discovery in music. In the first, regression models are built with the aim of predicting subjective assessments of a pattern's salience, based on various quantifiable attributes of that pattern, such as the number of notes it contains. Using variable selection and cross-validation, a formula is derived for rating the importance of a discovered pattern. In the second study, a music analyst undertook intra-opus pattern discovery for works by Domenico Scarlatti and Johann Sebastian Bach, forming a benchmark of target patterns. The performance of two existing algorithms and one of my own creation, called SIACT (Structure Induction Algorithm with Compactness Trawling), is evaluated by comparison with this benchmark. SIACT out-performs the existing algorithms with regard to recall and, more often than not, precision. A third experiment is reported concerning human judgements of music excerpts that are, to varying degrees, in the style of mazurkas by Frededric Chopin. This acts as an evaluation for two computational models of musical style, called Racchman-Oct2010 and Racchmaninof-Oct2010 (standing for RAndom Constrained CHain of MArkovian Nodes with INheritance Of Form), which are developed over two chapters. The latter of these models applies SIACT and the formula for rating pattern importance, using temporal and registral positions of discovered patterns from an existing template piece to guide the generation of a new passage of music. The precision and runtime of pattern discovery algorithms, and their use for audio summarisation are among topics for future work.

description: Sweet potato is considered a successful competitor against some weeds. Amaranthus dubius is a common weed that adversely affects sweet potato production throughout the Caribbean Basin. Limited research has been performed on weed interference in sweet potato under tropical conditions. In this scenario, understanding weed-crop relationships is fundamental for developing economical weed control strategies. A study was conducted to determine the effect of A. dubius interference on sweet potato mineral uptake under tropical conditions. Treatments included sweet potato without A. dubius, interspecific sweet potato with A. dubius, and A. dubius alone. At 5, 7, 9, 11 and 13 weeks after planting, two plants per plot and per species were cut at the soil level, washed and divided in leaf lamina, petiole and stem for nutrient concentration analyses. Interference by A. dubius significantly reduced sweet potato's uptake of Ν, Κ and Mg at 11 weeks after planting and later. Uptake of Ρ and Ca was reduced at 13 weeks after planting.

description: We present high-resolution VLT spectra of a new DO white dwarf and a new PG1159 star, which we identified in the ESO SPY survey. The PG1159 star is a low-gravity, extremely hot (Teff=160,000 K, log g=6) star, having a C/He dominated atmosphere with considerable amounts of O and Ne (He=38%, C=54%, O=6%, Ne=2% by mass). It is located within the planetary nebula nuclei instability strip and pulsations have been discovered. The DO is a unique object. From HeI/HeII line strengths we found Teff about 60,000 K, however, the HeII lines are extraordinarily strong and cannot be fitted by any model.

description: Facilitation between trophic levels during food web assembly can drive positive correlations in diversity between producers, consumers and decomposers. However, the contribution of trophic interactions relative to local environmental factors in promoting species diversity are poorly understood with many studies of food web assembly only considering two trophic levels. Here we examine correlations in diversity among zooplankton, phytoplankton and bacteria in the pelagic zone of 31 lakes in British Columbia. We sampled species diversity of zooplankton and phytoplankton through morphological identification while bacterial genetic diversity was estimated by denatured gradient gel electrophoresis (DGGE) of 16s rDNA polymorphisms. We looked for correlations in diversity that were independent of the abiotic environment by statistically controlling for 18 limnological variables. No strong correlation was found between the diversity of zooplankton, phytdplankton and bacteria. In addition, the physical factors that were associated with species composition in one trophic level were independent of those that were important for another. Our results provide no support for the importance of direct feedbacks between producers, consumers and decomposers in maintaining diversity. Zooplankton, phytoplankton and bacterial communities are structured independently from one another and respond to different environmental variables.
