A Discrete-Wavelength Imaging Instrument for the Remote Sensing of Nitrogen Dioxide from Space at High Spatial and Temporal Resolution
Creators: name: Villena, Cristina Ruiz

Year: 2021
Subjects: Uncategorized

description: Air pollution is a major environmental issue, causing millions of premature deaths worldwide and billions of pounds in economic losses every year. Nitrogen dioxide (NO2) is a key air pollutant and a good proxy for air quality. Reliable NO2 monitoring is key to understanding and tackling air pollution, and can be achieved at a global scale using satellite remote sensing. However, current and upcoming instruments do not provide the necessary spatio-temporal resolution to resolve fine-scale sources.This thesis explores a novel instrument concept, the High-resolution Anthropogenic Pollution Imager (HAPI), for use in a constellation of small satellites as a low-cost solution to the observational data gap. HAPI has only ten narrow spectral bands and uses a novel Discrete-Wavelength variant of the well-established Differential Optical Absorption Spectroscopy (DW-DOAS). This work evaluates a HAPI airborne demonstrator built at the University of Leicester during the OmniSat-HAPI project. Laboratory, field and flight tests were performed which showed consistently poor retrieval results. An investigation was conducted which confirmed that the cause of the poor retrieval performance was a suboptimal choice of wavelengths for NO2 nadir observations in combination with a DOAS-like method.A new set of wavelengths was identified and found to perform remarkably well. The robustness of DW-DOAS with the new wavelengths was evaluated by means of a sensitivity analysis, based on which new instrument performance requirements were defined for the next iteration of HAPI. While there are a few technical challenges to overcome, the OmniSat-HAPI constellation has the potential to provide NO2 observations at unprecedented spatial and temporal resolution, and would be a valuable complement to the existing air quality monitoring landscape.

description: We investigate the time evolution and asymptotic behavior of a system of two two-level atoms (qubits) interacting off-resonance with a single mode radiation field. The two atoms are coupled to each other through dipole-dipole as well as Ising interactions. An exact analytic solution for the system dynamics that spans the entire phase space is provided. We focus on initial states that cause the system to evolve to entanglement sudden death (ESD) between the two atoms. We find that combining the Ising and dipole-dipole interactions is very powerful in controlling the entanglement dynamics and ESD compared with either one of them separately. Their effects on eliminating ESD may add up constructively or destructively depending on the type of Ising interaction (Ferromagnetic or anti-Ferromagnetic), the detuning parameter value, and the initial state of the system. The asymptotic behavior of the ESD is found to depend substantially on the initial state of the system, where ESD can be entirely eliminated by tuning the system parameters except in the case of an initial correlated Bell state. Interestingly, the entanglement, atomic population and quantum correlation between the two atoms and the field synchronize and reach asymptotically quasi-steady dynamic states. Each one of them ends up as a continuous irregular oscillation, where the collapse periods vanish, with a limited amplitude and an approximately constant mean value that depend on the initial state and the system parameters choice. This indicates an asymptotic continuous exchange of energy (and strong quantum correlation) between the atoms and the field takes place, accompanied by diminished ESD for these chosen setups of the system. This system can be realized in spin states of quantum dots or Rydberg atoms in optical cavities, and superconducting or hybrid qubits in linear resonators.

The intermediate machine approach to distributed computing system design
Creators: name: Simon, Gordon Peter
Publisher: name: University of British Columbia
Year: 2010

description: This thesis proposes that an intermediate machine be viewed as the software base of a distributed operating system. In this role the services provided to the operating system by the intermediate machine are similar to those provided by a security kernel. Such an intermediate machine software base differs from the traditional security kernel in that it additionally provides an interpreted instruction set. The advantage of this approach is that software extension of a machine architecture - whereby multi-processing and device abstraction are provided - is implemented in a homogeneous manner across all nodes of the distributed computer system. The objective of the thesis is to determine the feasibility of an intermediate machine approach to distributed computer system design. Through investigation and experimentation, an intermediate machine based distributed computer system is developed and evaluated. This paper describes the system and its evaluation. As well, the merits of an intermediate machine software base are considered and the approach is contrasted with popular contemporary distributed system designs. Since it is expected that an interpretative intermediate machine would slow execution of system software, the focus of the project is in exploring this weakness in an effort to determine its extent. These efforts are to manifest in suggestions for a workable design of an intermediate machine based distributed computer.

description: The present document describes the regulatory framework and business models related to the INGENIOUS project. The regulatory framework has been approached from different perspectives. The document discusses the spectrum issues and frequency bands available in the regions where the use cases are taking place. It also describes the requirements and limitations at network level, security and privacy concerns, cryptocurrency aspects, as well as data protection issues. The deliverable also identifies and explores the current business models at strategic level that could be derived from the iNGENIOUS results. The document first provides a PESTEL analysis for providing context, and then tackles the technological enablers that may bring to the consortium new business models and opportunities. D2.3 also describes both regulatory and business aspects concerning each of the six use cases of iNGENIOUS.
A schema & constraint-based representation to understanding natural language
Creators: name: Kuttner, Eliza Wing-Mun
Publisher: name: University of British Columbia
Year: 2010

description: This thesis attempts to represent the syntax and semantics of English sentences using a schema and constraint-based approach. In this approach, syntactic and semantic knowledge that are represented by schemata are processed in parallel with the utilization of network consistency techniques and an augmented version of Earley's context-free parsing algorithm. A sentence's syntax and semantics are disambiguated incrementally as the interpretation proceeds left to right, word by word. Each word and recognized grammatical constituent provide additional information that helps to guide the interpretation process. It is desirable to attempt to apply network consistency techniques and schema-knowledge representations on understanding natural language since the former has been proven to be quite efficient and the latter provides modularity in representing knowledge. In addition, this approach is appealing because it can cope with ambiguities in an efficient manner. Multiple interpretations are retained if ambiguity exists as indicated by the words processed so far. However, incorrect interpretations are eliminated as soon as their inappropriateness is discovered. Thus, backtracking search which is known to be inefficient is avoided.

description: We determine the light quark masses from lattice QCD simulations incorporating the electromagnetic interaction of valence quarks. The meson masses are calculated on lattice QCD configurations generated by the RBC Collaboration for two flavors of dynamical domain wall fermions, which are combined with QED configurations generated via quenched non-compact lattice QED. The electromagnetic part of the pion mass splitting is found to be $m_{π^+}-m_{π^0}=4.12(21)$ MeV, where only the statistical error is quoted, and similarly for the kaon, 1.443(55) MeV. Our results for the light quark masses are $m_u^{\rm\bar{MS}}$(2 GeV)=$3.02(27)(19)$ MeV, $m_d^{\rm\bar{MS}}$(2 GeV)=$5.49(20)(34)$ MeV, and $m_s^{\rm\bar{MS}}$(2 GeV)=$119.5(56)(74)$ MeV, where the first error is statistical and the second systematic. By averaging over $\pm e$ to cancel ${\cal O}(e)$ noise exactly on each combined gauge field configuration, we are able to work at physical $α=1/137$ and obtain very small statistical errors. In our calculation, several sources of systematic error remain, including finite volume, non-zero lattice spacing, chiral extrapolation, quenched QED, and quenched strange quark, which may be more significant than the errors quoted above.

description: Cardiovascular disease is the number one cause of death globally, leading to high proportion of premature deaths. Since there is an aging population, the economic burden on health care systems increasingly requires the discovery of new biomarkers. Plasma proteomics is an approach to identify novel biomarkers using plasma. However, there are limitations with plasma due to the complexity and dynamic range between high abundant and low abundant proteins.Approaches of overcoming complexity and dynamic range include Molecular imprinting which is a promising tool in the field of proteomics. This thesis has created an imprint using polystyrene as substrate, which can be used to enrich albumin specifically with polymerised dopamine offering huge advantages such as polymerisation in the presence of urea. Dopamine does not require complex chemicals, scalable, cheap and biodegradable. Mouse heart organ was also used to create imprints to heart proteins onto polystyrene coated with polydopamine.Mass spectrometry was used to analyse proteins enriched from human plasma. A Nano-LC system was coupled to an Orbitrap (Q-Exactive) providing both quantitative and qualitative data. Both shotgun and targeted proteomics were employed. The Q-Exactive was operated using parallel reaction monitoring which utilises the high resolution capability of the Q-Exactive to quantitatively target peptides of proteins. Shotgun proteomics using data dependent acquisition was also employed to assess all proteins involved in the imprinting and enrichment. Extracts from molecular imprints (MIPs) contacted with plasma and their respective non-imprint controls (NIPs) were analysed using mass spectrometry. Results from mouse organ MIP contacted with plasma from five myocardial infarction patients, showed the presence of: Troponin, Fatty acid binding protein 3, Creatine Kinase, Lactate Dehydrogenase, Cardiac myosin binding protein C.The imprint created from tissue and organ shows the potential to analyse other tissue and organ MIPs to specifically study organ damage in other diseases, for example kidney, liver and lung injury related to COVID-19 and the effects of COVID-19 on organs.

description: The Lasserre Hierarchy is a set of semidefinite programs which yield increasingly tight bounds on optimal solutions to many NP-hard optimization problems. The hierarchy is parameterized by levels, with a higher level corresponding to a more accurate relaxation. High level programs have proven to be invaluable components of approximation algorithms for many NP-hard optimization problems. There is a natural analogous quantum hierarchy, which is also parameterized by level and provides a relaxation of many (QMA-hard) quantum problems of interest. In contrast to the classical case, however, there is only one approximation algorithm which makes use of higher levels of the hierarchy. Here we provide the first ever use of the level-$2$ hierarchy in an approximation algorithm for a particular QMA-complete problem, so-called Quantum Max Cut. We obtain modest improvements on state-of-the-art approximation factors for this problem, as well as demonstrate that the level-$2$ hierarchy satisfies many physically-motivated constraints that the level-$1$ does not satisfy. Indeed, this observation is at the heart of our analysis and indicates that higher levels of the quantum Lasserre Hierarchy may be very useful tools in the design of approximation algorithms for QMA-complete problems.

description: This paper presents a simple and efficient computer-aided diagnosis method to classify Chronic Myeloid Leukemia (CML) cells based on microscopic image processing. In the proposed method, a novel combination of both typical and new features is introduced for classification of CML cells. Next, an effective decision tree classifier is proposed to classify CML cells into eight groups. The proposed method was evaluated on 1730 CML cell images containing 714 cells of non-cancerous bone marrow aspiration and 1016 cells of cancerous peripheral blood smears. The performance of the proposed classification method was compared to manual labels made by two experts. The average values of accuracy, specificity and sensitivity were 99.0 %, 99.4 % and 98.3 %, respectively for all groups of CML. In addition, Cohen's kappa coefficient demonstrated high conformity, 0.99, between joint diagnostic results of two experts and the obtained results of the proposed approach. According to the obtained results, the suggested method has a high capability to classify effective cells of CML and can be applied as a simple, affordable and reliable computer-aided diagnosis tool to help pathologists to diagnose CML.

description: Stream Reasoning ist ein neues Forschungsfeld, das sich auf die semantische Auswertung von Datenstreams konzentriert. Für dieses Feld wurde das LARS Framework geschaffen; es benutzt Logik Programmierung und Datenströme der Answerset Semantik.In dieser Arbeit führen wir neue Formalismen für das LARS Framework ein, indem wir die LARS Programmiersprache in Metric Temporal Logic (MTL) übersetzen. Mit dieser Logik lassen sich Formeln sehr prägnant ausdrücken und sie wertet diese Formeln auf Timed State Sequences anstatt auf Datenströmen aus. Diese Timed State Sequences unterscheiden zwischen einer System- und einer Echtzeit.Durch die Übersetzung von LARS auf MTL erhalten wir ein neues MTL Fragment, das wir Metric LARS nennen. Dieses Fragment umfasst alle Formeln, die sich in LARS übersetzen lassen. Für Metric LARS und Timed State Sequences wird auch Answerset Semantik eingeführt.Timed State Sequences werden weiters auch genauer behandelt und wir beschäftigen uns mit verschiedenen Möglichkeiten diese in Datenströme zu übersetzen. Hier gibt es mehrere Optionen, jenachdem wie die temporalen Daten modelliert werden sollen.Wir werfen außerdem noch einen Blick auf andere mit MTL verwandte Real-Time Logics wie Metric Interval Temporal Logic, Signal Temporal Logic und deren semantischen Strukturen, sowie Timed Propositional Temporal Logic, welche die Mutter dieser Familie der Logik ist.
description: Stream Reasoning is a young field of study that focuses on the high level evaluation of data streams. The LARS framework was created for this task utilizing a logic based approach, modelling data streams and programs in Answer Set Programming fashion. We introduce a new formalism for the LARS framework by translating the LARS logic programming language to Metric Temporal Logic. This logic expresses formulas more succinctly than others and uses timed state sequences instead of streams as semantic structures, which distinguish between system- and real-time. By translating LARS to MTL and back we create a new MTL fragment, called Metric LARS, which describes the LARS-translatable forumlas, and provide answer set semantics for timed state sequences and Metric LARS programs. Timed state sequences are explored in detail on their own and we give various options to translate them to LARS streams and back, with methods that can be chosen depending on the semantics of the data to be modelled. We further create fragments of Metric LARS for Metric Interval Temporal Logic, Signal Temporal Logic and their respective semantic structures and have a look at Timed Propositional Temporal Logic and its relation with Metric LARS.

description: The Dirac equation for the electron around a five-dimensional rotating black hole with two different angular momenta is separated into purely radial and purely angular equations. The general solution is expressed as a superposition of solutions derived from these two decoupled ordinary differential equations. By separating variables for the massive Klein-Gordon equation in the same space-time background, I derive a simple and elegant form for the Stackel-Killing tensor, which can be easily written as the square of a rank-three Killing-Yano tensor. I have also explicitly constructed a symmetry operator that commutes with the scalar Laplacian by using the Stackel-Killing tensor, and the one with the Dirac operator by the Killing-Yano tensor admitted by the five-dimensional Myers-Perry metric, respectively.

Defending Technocracy? Communicating with the Public about Nuclear Energy: Historical Perspectives
Creators: name: McMullan, Joshua J.
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This thesis examines the communication strategy of the UK nuclear industry between 1975 to 1990. By refocusing the histories of this long-standing and contentious industry, I change our understanding of how the publicly funded nuclear industry saw and negotiated with, the UK publics. It makes new arguments about how nuclear science was communicated in post-war Britain and explores the inner workings of one of the best-funded industrial science communication projects during the period.The sixth report on nuclear power from the Royal Commission on Environmental Pollution intensified opposition to nuclear power and pushed the industry to reimagine how it communicated with the public. I argue that this required the industry to not just present data that showed that nuclear power was safe but to actively demonstrate it. Using previously unexplored primary material, I show that while the focus of the industry’s efforts was at public inquiries, it was through demonstrations, lectures, and the development of visitor centres where the industry used new communication methods for making not just a scientific argument for nuclear power, but an emotional one as well.Nevertheless, while the industry embarked on these new public relation ventures, it also maintained an extensive lobbying effort within the UK parliament, to ensure it maintained its legitimacy to exist. This lobbying effort spilt into its wider public relations effort as key industry figures such as Lord Walter Marshall and Sir John Hill created a hierarchy of communication, whereby decision-makers and influential people, such as parliamentarians and journalists were the focus of its communication strategy. While populations around nuclear sites also received additional attention in comparison to the wider public.The conclusion of this thesis reflects on what this untold history means for how we understand how the UK government and public bodies communicate science and how we view the relationship between government, parliament, and industry.

description: This report - “Report on the tool performance” – describes the three climate service tools developed for the olive/olive oil sector and the methodology followed for the calculation of the products that are available through the tools. The tool applications were developed through continuous feedback and interaction with the end-users. More specifically, the applications are: i) The Olivia platform, a web platform which includes a predictive pest management support system based on artificial intelligence ii) The MED-GOLD Dashboard, a web-based application that allows the users to easily visualise, interact and even download climate data and indices referring to seasonal or longer time scales. The calculation of the indices and the essential climate values (ECVs), which are the main products of the Dashboard, are described in a different section of this report. iii) The physiologically based demographic model (PBDM), an artificial intelligence (AI) based application, which captures the weather-driven biology of the interaction between olive and the olive fruit fly. The tools will be further improved in accordance with the feedback provided by the end-users who evaluated them during the second workshop that was held in May 2020 [RD.2].
A prolog implementation of a subset of Marcus’ parser and its relation to the handling of extragrammatical input
Creators: name: Dorotich, Michael Scarlett
Publisher: name: University of British Columbia
Year: 2010

description: In any system employing a natural language interface, there is the problem that, by means of a formal grammar, the system itself defines the language it will accept. But, when using language, people will not always adhere to the rules of this grammar; therefore, a natural language computer system should not simply treat as incomprehensible any input not conforming to its internal grammar, input we may call extragrammatical. The term extragrammatical refers to input that is not necessarily incorrect in an absolute sense but only relative to the formal scope of a system's grammar. Before a truly robust system can be developed, what is needed is a parsing mechanism that enforces grammaticality where possible, and this implies a deterministic approach to natural language parsing. This thesis discusses the importance of flexible natural language interfaces; the notion of extragrammatical language and its connexion to robust parsing; a deterministic parser, PARSIFAL, developed by Mitchell Marcus; and a reimplementation, using logic programming, of a subset of Marcus' system. Programming was done with CProlog on a VAX 11/750* running 4.2 BSD UNIX.

description: The processing of thin-structured materials in a fluidic environment, from nearly inextensible but flexible graphene sheets to highly extensible polymer films, arises in many applications. So far, little is known about the dynamics of such thin sheets freely suspended in fluid. In this work, we study the dynamics of freely suspended soft sheets in uniaxial extensional flow. Elastic sheets are modeled with a continuum model that accounts for in-plane deformation and out-of-plane bending, and the fluid motion is computed using the method of regularized Stokeslets. We explore two types of sheets: "stiff" sheets that strongly resist bending deformations and always stay flat, and "flexible" sheets with both in-plane and out-of plane deformability that can wrinkle. For stiff sheets, we observe a coil-stretch-like transition, similar to what has been observed for long-chain linear polymers under extension as well as elastic sheets under planar extension: in a certain range of capillary number (flow strength relative to in-plane deformability), the sheets exhibit either a compact or a highly stretched conformation, depending on deformation history. For flexible sheets, sheets with sufficiently small bending stiffness wrinkle to form various conformations. Here, the compact-stretched bistability still occurs, but is strongly modified by the wrinkling instability: a highly-stretched planar state can become unstable and wrinkle, after which it may dramatically shrink in length due to hydrodynamic screening associated with wrinkling. Therefore, wrinkling renders a shift in the bistability regime. In addition, we can predict and understand the nonlinear long-term dynamics for some parameter regimes with linear stability analysis of the flat steady states.

description: Fire has long been a fixture on African landscapes to which ecosystems, wildlife and people have adapted. Not surprisingly, wildland fire science in Africa has also undergone substantial change and development. Three broad eras of wildland fire science and management in sub-Saharan Africa have been described: An imperial period associated with European colonialism; an empirical period, during which fire research became more rigorous but remained reluctant to accept the role of humans; and an increasingly inclusive period, in which human dimensions of fire regimes are recognised and fire is understood to be part of complex landscape dynamics. Here we review the history of fire research in sub-Saharan Africa by analysing important literature from the past century, including a systematic review of peer-reviewed fire literature published by the Grassland Society of Southern Africa (GSSA) over the past six decades. We also highlight two important projects from the mid-20th century: the 1972 Proceedings of the 11th Tall Timbers Fire Ecology Conference in Tallahassee, Florida, USA – titled Fire in Africa – and the products of the South African programme on the Ecological Effects of Fire in South African Ecosystems, both being closely coupled to the fire literature published by the GSSA. We found that trends in fire science in Africa align well with the evolution of ecology as a global scientific discipline. We highlight evidence for transitions between the eras of understanding as they are reflected in contemporary publications, and critically analyse important contributions from South African publications. The empirical tradition of fire research is particularly strong in South Africa, but several colonial assumptions and scientific norms from the global north have persisted even as the interactions between wildland fire and human livelihoods are increasingly evident. The GSSA, in particular, has an opportunity to be an increasingly inclusive source for the exchange of fire knowledge from both social and ecological perspectives via its annual congresses and publications.

description: We identified 440 papers and 81 book reviews published chronologically by the Grassland Society of Southern Africa (GSSA) over 60 years, determined as making a contribution to understanding the drivers and response variables affecting the management and use of grassland and savanna rangelands in southern Africa as they relate to wildlife conservation and research. Established drivers and response variables considered critical in determining savanna and grassland structure and function in the wildlife context were used as discussion themes. Papers, based on title, keywords (where given) and author experience, were categorised as directly or indirectly relevant to the wildlife industry. Properties that were largely undisturbed or previously used for commercial production were included. The review yielded 106 papers that contribute directly to the wildlife industry and 334 from which principles have been adopted and adapted, largely from livestock systems. Including the book reviews, a total of 521 Journal contributions were accessed. The GSSA’s contribution, in the form of ‘wise use’ principles of sustainable management developed over 60 years, will increase as African economies exploit opportunities to utilise wildlife resources to the benefit of their citizens.

description: Rangelands offer various goods and ecosystem services (ES) besides providing forage for commercial livestock production. An analysis of research published in the journals of the Grassland Society of Southern Africa from 1966 to 2023 revealed a widening focus on different consumptive and non-consumptive ES. While livestock remains the primary focus, there is a growing interest in other provisional, regulatory, supporting, and cultural ES and uses of rangeland. The term ‘ecosystem services’ started to appear in articles from the early 2000s, marking a shift towards a richer discourse on the multifarious resources and services rangelands can provide to diverse users. A transition from ‘veld’ to ‘rangeland’ terminology occurred at the onset of the 21st century, though ‘veld’ remains mentioned. Recognition of communal and pastoral users of rangelands has expanded since the mid-1980s, alongside more frequent studies on conservation of biodiversity and commercial game production. Research has increasingly focused on understanding ecological processes supporting rangeland productivity and the provision of other ES, including carbon sequestration for climate regulation. Cultural and recreational values of rangelands have received little research attention. Overall, the journals’ corpus is evolving to reflect a broader perspective on valuing and managing multi-functional rangelands, which is in alignment with global research trends.

description: Woody plant encroachment is one of the most widespread land-cover changes in many countries. We put the data together along a precipitation gradient within southern Africa from 150 mm/annum (Namibia) to 1 500 mm/annum (eastern KwaZulu-Natal, South Africa). We found that extreme rainfall was the most important factor causing woody plant encroachment in semi-arid environments. In one mesic environment, transit through an animal, dung, simulated grazing and fire had important effects on encroachment. In the humid environment, we found that, without grass competition, shade was the most important factor. Grass competition was important in all environments. We found that there was a negative correlation between the change in soil carbon from open grasslands to paired encroached grasslands along the rainfall gradient, indicating that more carbon occurred in the soil at lower rainfall. In our conservation study, we found that the palatable tree species were being removed by herbivores and some of them were extirpated, and the unpalatable species were increasing in density. In sum, grass competition is a key factor across the gradient, but it is highly likely that global climate change (especially elevated CO2 and warming interactions) is the most important factor for woody plant encroachment. Key factors to study are facultative resprouting and plant–soil feedbacks.

description: We have carried out neutron powder-diffraction measurements on zinc paratacamite Zn$_x$Cu$_{4-x}$(OH)$_6$Cl$_2$ with $x=1$, and studied the heat capacity in fields of up to 9 T for $0.5 \leq x \leq 1$. The $x=1$ phase has recently been shown to be an outstanding realisation of the $S=1/2$ kagomé antiferromagnet. A weak mixing of Cu$^{2+}$/Zn$^{2+}$ between the Cu and the Zn sites, corresponding to $\sim 9$% of all Cu$^{2+}$ for $x=1$, is observed using neutron diffraction. This ``antisite disorder'' provides a consistent explanation of the field dependence of the heat capacity for $0.8 \leq x \leq 1$. From comparison of the derived Cu$^{2+}$ occupancy of the Zn sites for $x = 0.8... 1$ with the magnetic susceptibility, we argue that for $x = 0.8... 1$ zinc paratacamite is a spin liquid without a spin gap. The presence of unpaired but nevertheless strongly interacting spins gives rise to a macroscopically degenerate ground state manifold, with increasingly glassy dynamics as $x$ is lowered.

Implementation methods for singularly perturbed two-point boundary value problems
Creators: name: Jacobs, Simon
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis we consider the numerical solution of singularly perturbed two-point boundary value problems in ordinary differential equations. We examine implementation methods for general purpose solvers of first order linear systems. The basic difference scheme is collocation at Gauss points, with a new symmetric Runge-Kutta implementation. Adaptive mesh selection is based on localized error estimates at the collocation points. These methods are implemented as modifications to the successful collocation code, COLSYS (Ascher, Christiansen & Russell), which was designed for mildly stiff problems only. Efficient high order approximations to extremely stiff problems are obtained, and comparisons to COLSYS show that the modifications work much better as the singular perturbation parameter gets small (i.e. the problem gets stiff), for both boundary layer and turning point problems.

description: This document reports the first end-users’ evaluation of the elements that have been proposed in the preliminary version of the climate service tool. The feedback was obtained in a workshop held at SOGRAPE VINHOS S.A. involving different staff members responsible for taking decisions in areas where climate factors have a role. From this exercise, the kind of visualization and information that would be important for these users became clear. Changes required to adapt the beta version of the tool to meet users’ expectations were identified.
Modelling and animating three-dimensional articulate figures
Creators: name: Cachola, Danny G.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes an animation extension to a high-level graphical programming language which provides constructs for the definition, manipulation, and external representation of three-dimensional articulate figures and and their associated movements. The extension permits the definition of models consisting of segments and joints and the specification of each model's motion at a high level of abstraction. The relationship of the extension with respect to the host language is discussed and a general description of the animation language's design and implementation is given. The modelling and motion constructs are discussed and examples of the constructs are presented. It is concluded that high level animation permits the implementation of sophisticated application programs that are easy to read and understand.

description: Durch das Aufkommen allgemein verfügbarer Quantencomputer stellt sich die Frage, warum nicht das Potenzial dieser neuen Technologie nutzen, um bestehende oder ganz neue Fragen der Digital Humanities zu adressieren? Besonders im Bereich des Quanten-basierten Maschinellen Lernens lassen sich mit den heute verfügbaren Quantencomputer bereits Ergebnisse erzielen, welche klassischen Lösungen teils überlegen sind. Dies zum Beispiel ist für die Digital Humanities mit stetig wachsenden Datenmengen und einhergehenden Analyseanforderungen relevant. Um solche Potenziale des Quantencomputers auszuloten, möchten wir QHAna vorstellen, welches den Vergleich der Ergebnisse klassischer und Quanten-basierter Verfahren des Maschinellen Lernens erlaubt.
description: With the advent of widely available quantum computers, the question arises why not use the potential of this new technology to address existing or entirely new questions in the Digital Humanities? Especially in the field of quantum-based machine learning, the quantum computers available today can already achieve results that are partially superior to classical solutions. This is, for example, relevant for the Digital Humanities with steadily growing data volumes and accompanying analysis requirements. To explore such potentials of quantum computing, we would like to present QHAna, which allows the comparison of the results of classical and quantum-based machine learning methods.
