Creators: name: Alabri, Waleed
Publisher: name: University of Lincoln
Year: 2023
Subjects: X900 - Others in education

description: The inclusion of children with Down’s syndrome in Saudi Arabian schools is in a state of stress and confusion. School leaders have a critical role in improving inclusion, and they are also well placed to understand the challenges of their own schools. This research explores the perspectives of school principals on the inclusion of pupils with Down’s syndrome in mainstream Saudi schools and factors that affect it.This study consists of a qualitative study of inclusive schools (both government and ARAMCO) in the Eastern Province. Three methods were employed for data collection: interviews with a purposive sample of principals from 20 inclusive schools, the analysis of five government documents, and participant observation in five schools.The principals lacked knowledge about inclusion-associated policy, particularly regarding children with Down’s syndrome, which influenced their perspectives and had an impact on the strategies they adopted regarding inclusive learning for children with Down’s syndrome in their schools. Principals from government schools also reported unsuitability of school buildings and lack of funding for improvements, whereas ARAMCO school buildings were better designed for inclusion. For both types of schools, additional limiting factors included the profundity of the learning difficulties of children with Down’s syndrome and the training required by principals.Recommendations are also made regarding infrastructure, apparatus and resources that aid inclusion, and for measures to foster community awareness and leadership training. Collectively, it is hoped that this will result in the fruitful inclusion of children with Down’s syndrome within education and society in Saudi Arabia.

description: We studied phase separation in a single-crystalline antiferromagnetic superconductor Rb2Fe4Se5 (RFS) using a combination of scattering-type scanning near-field optical microscopy (s-SNOM) and low-energy muon spin rotation (LE-μSR). We demonstrate that the antiferromagnetic and superconducting phases segregate into nanometer-thick layers perpendicular to the iron-selenide planes, while the characteristic in-plane size of the metallic domains reaches 10 μm. By means of LE-μSR we further show that in a 40-nm thick surface layer the ordered antiferromagnetic moment is drastically reduced, while the volume fraction of the paramagnetic phase is significantly enhanced over its bulk value. Self-organization into a quasiregular heterostructure indicates an intimate connection between the modulated superconducting and antiferromagnetic phases.

Paradisi impossibili. Spazi vegetali nel romanzo fin-de-siècle
Creators: name: Carmagnani, Paola
Publisher: name: Università degli  Studi di Milano
Year: 2012

description: This essay discusses the modern novel’s attempt to create edenic spaces of natural innocence. It focuses on two French novels, La Faute de l’Abbé Mouret by Emile Zola (1875) and Le Mariage de Loti by Pierre Loti (1880), which both unsuccessfully try to build an edenic chronotope : a vegetal Paradise where time stops being a source of distruction, and where life seems to recover its lost signification. The analysis of these narratives will show that the construction of this kind of space has become, in the modern novel, a difficult and contradictory operation. Moreover, this renewed natural Eden appears incapable of containing the plot : it closes up on itself , expelling the heroes who inhabited it and rejecting them  into the conflictual and incoherent space of Culture to which they belong. This unsuccessful construction leads the narratives to a contradictory representation of Nature, which becomes an uncanny space where the dark figures of the unconscious reveal the unsatisfactory illusion of the edenic chronotope. In this respect, these two narratives significatively rejoin the literary model which will dominate the representation of Natural spaces in the European novel by the end of the nineteenth century.

The fundamental dissolution kinetics of silver sulfide and mercury sulfide in atmospheric cyanide solutions
Creators: name: Joon Won, Lee
Publisher: name: University of British Columbia
Year: 2013

description: The dissolution kinetics of pure silver sulfide (acanthite) and mercury sulfide (metacinnabar) were investigated using rotating disc and stirred reactor methods and the results were explained using the Levich and shrinking-core Parabolic Leach equations, respectively. It was observed that silver sulfide dissolution was limited by cyanide mass-transport and mercury sulfide by parabolic leaching. Silver sulfide leaching was practically unaffected by pH and dissolved oxygen concentrations while mercury sulfide leaching was sensitive to both parameters. Dissolution rates of both species increased linearly with cyanide concentration and activation energies were calculated using the Arrhenius rate equation as 5.15kJ/mol and 5.81kJ/mol, respectively, which indicates mass-transport control. It was also considered that silver sulfide dissolution is supressed by sulfide-saturation in the solution, while mercury dissolution is inhibited by the growth of sulfur-rich product layers on the particles. Kinetic results were compared to extraction experiments conducted on a spent Heap Leach Residue sample from the Yanacocha Mine in Peru which contained acanthite and cinnabar as its primary silver and mercury species. Extraction kinetics of silver from the Leach Residue was analogous to pure silver sulfide’s experimental results, except that extraction rates decreased with pH. Mercury extraction from the residue was insensitive to both cyanide and pH, but was responsive to oxygen concentration. The discrepancies between pure sample investigations and the Leach Residue suggest that unforeseen interactions with other minerals may be affecting the extraction rates of silver and mercury from the Yanacocha Mine.
Mean field conditions for coalescing random walks
Creators: name: Oliveira, Roberto Imbuzeiro
Publisher: name: arXiv
Year: 2011
Subjects: subject: Probability (math.PR)

description: The main results in this paper are about the full coalescence time $\mathsf{C}$ of a system of coalescing random walks over a finite graph $G$. Letting $\mathsf{m}(G)$ denote the mean meeting time of two such walkers, we give sufficient conditions under which $\mathbf{E}[\mathsf{C}]\approx 2\mathsf{m}(G)$ and $\mathsf{C}/\mathsf{m}(G)$ has approximately the same law as in the "mean field" setting of a large complete graph. One of our theorems is that mean field behavior occurs over all vertex-transitive graphs whose mixing times are much smaller than $\mathsf{m}(G)$; this nearly solves an open problem of Aldous and Fill and also generalizes results of Cox for discrete tori in $d\geq2$ dimensions. Other results apply to nonreversible walks and also generalize previous theorems of Durrett and Cooper et al. Slight extensions of these results apply to voter model consensus times, which are related to coalescing random walks via duality. Our main proof ideas are a strengthening of the usual approximation of hitting times by exponential random variables, which give results for nonstationary initial states; and a new general set of conditions under which we can prove that the hitting time of a union of sets behaves like a minimum of independent exponentials. In particular, this will show that the first meeting time among $k$ random walkers has mean $\approx\mathsf{m}(G)/\bigl({\matrix{k 2}}\bigr)$.

description: We study the anisotropic effect of the Coulomb interaction on a 1/3-filling fractional quantum Hall system by using an exact diagonalization method on small systems in torus geometry. For weak anisotropy the system remains to be an incompressible quantum liquid, although anisotropy manifests itself in density correlation functions and excitation spectra. When the strength of anisotropy increases, we find the system develops a Hall-smectic-like phase with a one-dimensional charge density wave order and is unstable towards the one-dimensional crystal in the strong anisotropy limit. In all three phases of the Laughlin liquid, Hall-smectic-like, and crystal phases the ground state of the anisotropic Coulomb system can be well described by a family of model wave functions generated by an anisotropic projection Hamiltonian. We discuss the relevance of the results to the geometrical description of fractional quantum Hall states proposed by Haldane [ Phys. Rev. Lett. 107 116801 (2011)].

Conceptions of time and form in twentieth and twenty-first-century music
Creators: name: Scheuregger, Martin
Publisher: name: University of Lincoln
Year: 2023
Subjects: W300 - Music

description: This thesis takes an interdisciplinary approach, combining composition and analysis to explore a series of musical notions associated with time and form in twentieth and twenty-first century music. Four ideas are investigated through analytical case studies of music by Webern, Stravinsky, György Kurtág and George Benjamin, alongside interlinked original compositions. Whilst the selected works share broad underlying concerns, a parallel between the composers? broader oeuvres is not asserted. Rather, the folio can be seen as addressing two interlinked topics, each with two related halves: brevity, through fragmentation and miniaturisation; and connectedness, through continuity and organicism. An all-encompassing view of the themes is not sought; instead, by demonstrating the idiosyncrasies in approach in both existing and original works, a diversity of information is gathered that provides individual not archetypal examples. It is shown that unity can be achieved in fragmented works by taking into account non-linear associations, whilst in miniature works a synthesis of form and content creates cohesion. Furthermore, continuity can be created despite block-like structures, whilst notions of organicism require new approaches to musical material. Through a synthesis of approaches that combines elements of practice-led and practice-based research, these temporal themes are explored in a manner that provides insight for both composers and listeners: conceptual issues are highlighted, their application in new works is demonstrated, and their precedents in extant pieces are explored. The analytical case studies are principally concerned with manners in which a work might be experienced, and how an awareness of form and the manipulation of time can inform this, whilst the compositions offer an individual approach to each theme, aiming to engage with the listening experience by actively exploring the stated ideas.

description: In this paper, we study Einstein gravity with a minimally coupled scalar field accompanied with a potential, assuming an O(4) symmetric metric ansatz. We call an Euclidean instanton is to be an oscillating instanton, if there exists a point where the derivative of the scale factor and the scalar field vanish at the same time. Then we can prove that the oscillating instanton can be analytically continued, both as inhomogeneous and homogeneous tunneling channels. Here, we especially focus on the possibility of a homogeneous tunneling channel. For the existence of such an instanton, we have to assume three things: (1) there should be a local maximum and the curvature of the maximum should be sufficiently large, (2) there should be a local minimum and (3) the other side of the potential should have a sufficiently deeper vacuum. Then, we can show that there exists a number of oscillating instanton solutions and their probabilities are higher compared to the Hawking-Moss instantons. We also check the possibility when the oscillating instantons are comparable with the Coleman-DeLuccia channels. Thus, for a general vacuum decay problem, we should not ignore the oscillating instanton channels.

description: The new photometric data on the δ Scuti star HD46190 (TIC150394126) obtained recently with the Transiting Exoplanet Survey Satellite (TESS) are analysed to search for stellar pulsations. From the best fit of Balmer line profiles with a synthetic spectrum we have estimated its Teff = 8640 ∓ 100 K, log g = 4.0 ∓ 0.1, metallicity [M/H] = -0.7 ∓ 0.1, and substantial rotational velocity v sin(i) = 235 ∓ 2 km/s. Our analysis of the light curve accumulated over one year shows that HD46190 exhibits stellar pulsations with significant amplitudes (SNR > 4) in the spectral domain from 0.15 to 112 d-1. For the signals detected in the domain from 35 to 70 d-1 the best fitting model with 2 M⊙ and age around 5.44x108 years corresponds to the large frequency separation Δν= 4.75 d-1 and the core hydrogen fraction fov = 0.33. For two signals at 49.088 d-1 and 58.583 d-1 with the highest amplitudes we have found a long term variability of their amplitudes with time, which is most probably caused by beating of two or more nearby frequencies.

Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In the framework of gauge invariant approach involving Stueckelberg and auxiliary fields, totally symmetric arbitrary spin anomalous conformal current and shadow field in flat space-time of dimension greater than or equal to four are studied. Gauge invariant differential constraints for such anomalous conformal current and shadow field and realization of global conformal symmetries are obtained. Gauge invariant two-point vertex of the arbitrary spin anomalous shadow field is also obtained. In Stueckelberg gauge frame, the two-point gauge invariant vertex becomes the standard two-point vertex of CFT. Light-cone gauge two-point vertex of the arbitrary spin anomalous shadow field is derived. The AdS/CFT correspondence for arbitrary spin anomalous conformal current and shadow field and the respective normalizable and non-normalizable modes of massive arbitrary spin AdS field is studied. The AdS field is considered in modified de Donder gauge which simplifies considerably the study of AdS/CFT correspondence. We show that on-shell leftover gauge symmetries of bulk massive field are related to gauge symmetries of boundary anomalous conformal current and shadow field, while the modified de Donder gauge condition for bulk massive field is related to differential constraints for boundary anomalous conformal current and shadow field.

An interesting class of such functions can be (conjecturally) obtained from a pair $(X,X')$ of diagrams, each of which is either a Dynkin diagram of type $ADE$ or a diagram of type $T$. Using properties of Y-systems, we prove that for a matrix of the form $A=\mathcal{C}(X)\otimes \mathcal{C}(X')^{-1}$ where $\mathcal{C}(X)$ and $\mathcal{C}(X')$ are the corresponding Cartan matrices, every solution of the equation $\mathbf{x}=(1-\mathbf{x})^A$ gives rise to a torsion element of the Bloch group.

Dynamic average-value model of high power ac-dc converters and HVDC systems
Creators: name: Atighechi, Hamid
Publisher: name: University of British Columbia
Year: 2013

description: High power switching converters such as line-commutated converters (LCC) and high voltage direct current (HVDC) systems are widely used in modern energy grids for interconnection of industrial loads, large motor drives, as well as electronically-interfaced renewable/alternative/distributed energy resources (DER) and storage systems. For design and analysis of systems with power-electronic-based DERs and loads, accurate and efficient computer models are essential. This thesis is focused on dynamic average-value models (AVM) that neglect switching of converter circuits and are established by averaging the variables (currents and voltages) over a prototypical switching interval. The AVMs are continuous (free of switching), allow using larger integration time steps, and typically run much faster than the conventional detailed switching models, which makes them particularly useful for the system-level studies. This thesis considers the parametric AVM framework, and extends this approach to the thyristor-controlled LCCs operating in inverter mode with current source or voltage source control. The proposed modeling methodology is demonstrated on various topologies including the HVDC CIGRE benchmark system. The research is further extended to incorporate the ac side harmonics into the AVM using the multiple reference frame theory. Traditionally, the AVMs are developed using state-variable-based approach. This thesis also presents a new parametric AVM for direct interfacing in nodal-analysis-based electromagnetic transient programs (EMTP), e.g., PSCAD/EMTDC, EMTP-RV, and MicroTran. It is expected that the proposed models and interfacing approaches will find their application in widely used transient simulation tools and will be appreciated by many researchers and practicing engineers worldwide.

Towards a Dynamic Vision System - Computational Modelling of Insect Motion Sensitive Neural Systems
Creators: name: Fu, Qinbing
Publisher: name: University of Lincoln
Year: 2023
Subjects: I100 - Computer science

description: For motion perception, vision plays an irreplaceable role, which can extract more abundant useful movement features from an unpredictable dynamic environment compared to other sensing modalities. Nowadays, building a dynamic vision system for motion perception in a both reliable and efficient manner is still an open challenge. Millions of years of evolutionary development has provided, in nature, animals that possess robust vision systems capable of motion perception to deal with a variety of aspects of life. Insects, in particular, have a relatively smaller number of visual neurons compared to vertebrates and humans, but can still navigate smartly through visually cluttered and dynamic environments. Understanding the insects' visual processing pathways and methods thus are not only attractive to neural system modellers but also critical in providing effective solutions for future intelligent machines.Originated from biological researches in insect visual systems, this thesis investigates computational modelling of motion sensitive neural systems and potential applications to robotics. This proposes novel modelling of the locust and fly visual systems for sensing looming and translating stimuli. Specifically, the proposed models comprise collision selective neural networks of two lobula giant movement detectors (LGMD1 and LGMD2) in locusts, and translating sensitive neural networks of direction selective neurons (DSNs) in flies, as well as hybrid visual neural systems of their combinations. In all these proposed models, the functionality of ON and OFF pathways is highlighted, which separate visual processing into parallel computation. This works effectively to realise neural characteristics of both the LGMD1 and the LGMD2 in locusts and plays crucial roles in separating the different looming selectivity between the two visual neurons. Such a biologically plausible structure can also implement the fly DSNs for translational movements perception and guide fast motion tracking with a behavioural response to visual fixation. The effectiveness and flexibility of the proposed motion sensitive neural systems have been validated by systematic and comparative experiments ranging from off-line synthetic and real-world tests to on-line bio-robotic tests. The underlying characteristics and functionality of the locust LGMDs and the fly DSNs have been achieved by the proposed models. All the proposed visual models have been successfully realised on the embedded system in a vision-based ground mobile robot. The robot tests have verified the computational simplicity and efficiency of proposed bio-inspired methodologies, which hit at great potential of building neuromorphic sensors in autonomous machines for motion perception in a fast, reliable and low-energy manner.

description: In this paper we have added Maxwell, Maxwell-Chern-Simons and gravitational Chern-Simons terms to Born-Infeld extended new massive gravity and we have found different types of (non)extremal charged black holes. For each black hole we find mass, angular momentum, entropy and temperature. Since our solutions are asymptotically AdS or warped-AdS, we infer central charges of dual CFTs by using Cardy's formula. Computing conserved charges associated to asymptotic symmetry transformations confirms calculation of central charges. For CFTs dual to asymptotically AdS solutions we find left central charges from Cardy's formula, while conserved charge approach gives both left and right central charges. For CFTs dual to asymptotically warped-AdS solutions, left and right central charges are equal when we have Maxwell-Chern-Simons term but they have different values when gravitational Chern-Simons term is included.

description: We show that the one-loop effective potential of spontaneously broken N=8 supergravity is calculable and finite at all classical four-dimensional Minkowski vacua without tachyons in the spectrum. The reason is that the supertraces of the quadratic and quartic mass matrices vanish along the classically flat directions: Str M^2 = Str M^4 =0. We also show that Str M^6 = 0 but Str M^8 > 0 in a broad class of vacua with broken supersymmetry on a flat background, which includes all those explicitly identified so far. We find analytical and numerical evidence that the corresponding one-loop effective potential is negative-definite.

Translating Cultural References in Tourism Discourse: the Case of the Apulian Region
Creators: name: Petillo, Mariacristina
Publisher: name: Università degli  Studi di Milano
Year: 2012
Subjects: Languaging; Cultural references; Translation Studies; Language of tourism

description: The aim of this paper is to provide a reflection on cultural references in tourism discourse, highlighting the difficulties translators may face when dealing with culture-bound words (Newmark 1988: 95-102; Katan 1999: 45-65; Oltra Ripoll 2005: 76-78). On the basis of a corpus of texts belonging to different genres, this study will investigate how the lexical features described by G. Dann in terms of languaging (1996: 183) are differently displayed and distributed, and whether a different rate of languaging could be said to enhance or detract from the communicative effectiveness of the selected texts: a guidebook, a monograph and five tourist brochures about the Southern Italian region of Apulia. Some of the most relevant translation choices will be reflected upon, showing how different communicative strategies are at work and end up producing “a different emphasis and degree of explanation” (Poncini 2006: 145) in the foreign tourists’ comprehension of Apulian cultural references.

Integrating sustainability in municipal wastewater infrastructure decision-analysis using the analytic hierarchy process
Creators: name: Galal, Hana Sherin
Publisher: name: University of British Columbia
Year: 2013

description: New regulations from the Canadian Council of Ministers of Environment, released in 2009, require all wastewater treatment plants in Canada to produce effluent of secondary treatment levels. To comply with the new law, many Canadian municipalities using primary treatment plants must retrofit or renew their old systems. There is an increasing pressure from stakeholder groups and policy makers to select new infrastructure using triple-bottom-line (economic, environmental and social) analyses. The present study aims to illuminate how differing preferences among experts from different stakeholder groups influence what is considered to be the ‘most sustainable' wastewater treatment system. Through the use of policy documents, academic literature, and the use of AHP (a decision support tool: Analytic Hierarchy Process) an objectives hierarchy was constructed. The objectives hierarchy was made up of four criteria and 13 indicators. Five wastewater experts were asked to use pair-wise comparisons to score the indicators and criteria of the constructed objectives hierarchy and provide their opinions on the same. In addition, four low foot-print wastewater treatment alternatives were selected for review. One of the participants was asked to rank the four alternatives with regards to their performance on the selected indicators. This ranking, in combination with the rankings of the indicators and criteria, previously made by the five experts, were used to indicate the preferred alternatives for each of the separate participants. Then, the overall prioritization of the alternatives was used to carry out a sensitivity analysis. In terms of results, this study of sustainability indicators for wastewater treatment selection showed that the most contentious indicators among those studied were Initial Costs and Long Term Costs, Effluent Quality and Aesthetics. Additionally, the study showed that the Sequencing Batch Reactor was identified as the ‘most sustainable’ alternative by the average scores of all five participants and separately by four of the five participants.

description: This paper is in line with a national research project (PRIN) about the Language of Tourism in Spanish and Italian: Lexical, Pragmatic and Intercultural Aspects. Our aim is to contribute to the study of digital tourist texts adopting a methodological perspective based on the most recent studies about the rhetoric of advertising, web advertising and institutional communication. We carry out a contrastive analysis of the headlines introducing news and press releases published on line within five promotional and touristic websites, those of the expositions of Sevilla (1992), Zaragoza (2008), Shanghai (2010, Italian pavilion), Shanghai (2010, Spanish pavilion), and Milan (2015).

Stokes flow near the contact line of an evaporating drop

description: The evaporation of sessile drops in quiescent air is usually governed by vapour diffusion. For contact angles below $90^\circ$, the evaporative flux from the droplet tends to diverge in the vicinity of the contact line. Therefore, the description of the flow inside an evaporating drop has remained a challenge. Here, we focus on the asymptotic behaviour near the pinned contact line, by analytically solving the Stokes equations in a wedge geometry of arbitrary contact angle. The flow field is described by similarity solutions, with exponents that match the singular boundary condition due to evaporation. We demonstrate that there are three contributions to the flow in a wedge: the evaporative flux, the downward motion of the liquid-air interface and the eigenmode solution which fulfils the homogeneous boundary conditions. Below a critical contact angle of $133.4^\circ$, the evaporative flux solution will dominate, while above this angle the eigenmode solution dominates. We demonstrate that for small contact angles, the velocity field is very accurately described by the lubrication approximation. For larger contact angles, the flow separates into regions where the flow is reversing towards the drop centre.

title: DEPRECATED: CAN HEALTH VISITORS ASSIST CLIENTS TO OPTIMISE HEALTH-DETERMINING ASPECTS OF THE INDOOR ENVIRONMENT THROUGH PROVISION OF EVIDENCE-INFORMED MESSAGES?
Creators: name: RICHARDSON, GEORGE
Publisher: name: University of Plymouth
Year: 2009

description: The aim of the research was to investigate the acceptability and feasibility of health visitors working with their clients to assess health-determining aspects of their clients' home environments and to provide evidence-informed messages about the indoor environment. The research was conducted within a Soft Systems Methodology framework. Following a pilot study in 2003, a proof of concept, feasibility study was implemented (2004 to 2007) with a convenience sample of eight health visitors conducting 29 environmental assessments in clients' homes, using a dedicated, cost effective tool kit. The health visitors were trained to monitor and provide evidence-based messages on Indoor environmental quality. Their quantitative and qualitative data from the assessments were compared against a 'gold standard' assessment carried out by an indoor environmental expert. The health visitors' opinions of the concept were investigated using participant observation and face-to-face interviews. The aim and objectives of the research were met. The health visitors were able to collect accurate data. Changes to the tool kit would be needed to adapt it specifically for health visitors. The majority of the health visitors found the concept acceptable and relevant to their work. The study has added to knowledge, in that the feasibility and acceptability of health visitors helping their clients with indoor environmental problems is now more clearly understood. It confirms previous findings that home visiting health professionals are not well informed about health-determining aspects of the indoor environment. Lack of time and resources could be a barrier to health visitors participating in research.
Partition functions of N=(2,2) gauge theories on S^2 and vortices

description: We apply localization techniques to compute the partition function of a two-dimensional N=(2,2) R-symmetric theory of vector and chiral multiplets on S^2. The path integral reduces to a sum over topological sectors of a matrix integral over the Cartan subalgebra of the gauge group. For gauge theories which would be completely Higgsed in the presence of a Fayet-Iliopoulos term in flat space, the path integral alternatively reduces to the product of a vortex times an antivortex partition functions, weighted by semiclassical factors and summed over isolated points on the Higgs branch. As applications we evaluate the partition function for some U(N) gauge theories, showing equality of the path integrals for theories conjectured to be dual by Hori and Tong and deriving new expressions for vortex partition functions.
