description: In this paper, we establish the Cowling--Price's, Hardy's and Morgan's uncertainty principles for the Opdam-Cherednik transform on modulation spaces associated with this transform. The proofs of the theorems are based on the properties of the heat kernel associated with the Jacobi-Cherednik operator and the versions of the Phragm{é}n-Lindl{ö}f type result for the modulation spaces.

description: Eisenstadt ist seit geraumer Zeit an einem Punkt angelangt, an dem es seine aufkommende Urbanität nicht mehr verbergen könnte. Die Identitätskrise, sich weder als urbane Bühne eines Stadtgeschehens, noch als überschaubares Dorf wahrzunehmen, scheint zum Teil überwunden zu sein. Gerade deshalb ist die thematische Auseinandersetzung mit dem Umgang zweier Seelen dieser Stadt, einer dem Dorf entsprungenen und einer der Urbanität zugewandten, notwendiger denn je. Die Beschäftigung mit dem aktuellen Entwicklungsstatus Eisenstadts und das Spannungsfeld zweier Charakteristika, die auf vielfältige und spannende Art und Weise in der Stadt sichtbar werden, werfen sowohl die Frage hinsichtlich eines sinnvollen Umgangs mit der strukturellen Herkunft des Ortes und seinen gegenwärtigen Identifikationswerten als auch urbanen Leitmotiven für die Zukunft auf. Für den regionalen Wohnbau bedeutet dies einen Paradigmenwechsel, sodass auf ursprüngliche Strukturen der Örtlichkeit ebenso Bezug genommen werden kann, wie auch Raum für nachhaltige Innovationen zugelassen wird. Im Rahmen dieses Projektes wird versucht, dem Spannungsfeld zwischen Dorf und Stadt einen Aktionsraum zu bieten, der unter anderem Aspekte wie Nachverdichtung im innerstädtischen Raum, Öffentlichkeit und Privatheit sowie horizontale Verdichtungsformen im Wohnbau zum Inhalt hat.
description: For a considerable time Eisenstadt has reached a point when urbanism could not be disguised anymore. It seems, that the identity crisis of neather beeing a stage of urban life nor discerning as a manageable village, is partly overcome. Therefore the analysis of two souls of this town, one arising of the village and one of facing the urbanism, is more necessary than ever. The analysis of the current state of development and also being between poles of two characteristics, which appear varied in exciting ways, are posing questions of a useful handling with the structural origin, its current recognizability and urban leitmotif for the future. For regional housing this is forcing a paradigm change, so that there can be made a reference on originally structurals of the venue and admitted space for sustainable innovations. Within the context of this project, a field is being attempted to create an action space between village and town including further aspects of housing like post densification in intraurban space, public and privacy plus horizontal forms of densification.

description: We explore some fundamental differences in the phenomenology, cosmology and model building of Split Supersymmetry compared with traditional low-scale supersymmetry. We show how the mass spectrum of Split Supersymmetry naturally emerges from theories where the dominant source of supersymmetry breaking preserves an $R$ symmetry, characterize the class of theories where the unavoidable $R$-breaking by gravity can be neglected, and point out a new possibility, where supersymmetry breaking is directly communicated at tree level to the visible sector via renormalizable interactions. Next, we discuss possible low-energy signals for Split Supersymmetry. The absence of new light scalars removes all the phenomenological difficulties of low-energy supersymmetry, associated with one-loop flavor and CP violating effects. However, the electric dipole moments of leptons and quarks do arise at two loops, and are automatically at the level of present limits with no need for small phases, making them accessible to several ongoing new-generation experiments. We also study proton decay in the context of Split Supersymmetry, and point out scenarios where the dimension-six induced decays may be observable. Finally, we show that the novel spectrum of Split Supersymmetry opens up new possibilities for the generation of dark matter, as the decays of ultraheavy gravitinos in the early universe typically increase the abundance of the lightest neutralino above its usual freeze-out value. This allows for lighter gauginos and Higgsinos, more accessible both to the LHC and to dark-matter detection experiments.

description: In the paper we consider Riemannian surfaces admitting a global expression of the Gauss curvature as the divergence of a vector field. It is equivalent to the existence of a metric linear connection of zero curvature. Such a linear connection $\nabla$ plays an important role in the differential geometry of non-Riemannian surfaces in the sense that the Riemannian quadratic forms can be changed into Minkowski functionals in the tangent planes such that the Minkowskian length of the tangent vectors is invariant under the parallel translation with respect to $\nabla$ (compatibility condition). A smoothly varying family of Minkowski functionals in the tangent planes is called a Finslerian metric function under some regularity conditions. Especially, the existence of a compatible linear connection provides the Finsler surface to be a so-called generalized Berwald surface. It is an alternative of the Riemannian geometry for $\nabla$. Using some general observations and topological obstructions we concentrate on explicit examples. In some representative cases (Euclidean plane, hyperbolic plane etc.) we solve the differential equation of the parallel vector fields to construct a smoothly varying family of Minkowski functionals in the tangent planes such that the Minkowskian length of the tangent vectors is invariant under the parallel translation.

description: The Generation and propagation of the human voice is studied in two-dimensions using a full-body domain, using direct numerical simulation. The fluid/air in the vocal tract is modeled as a compressible and viscous fluid interacting with the non-linear, viscoelastic vocal folds (VF). The VF tissue material properties are multi-layered, with varying stiffness, and a finite-strain model is utilized and implemented in a quadratic finite element code. The fluid-solid domains are coupled through a boundary-fitted interface and utilize a Poisson equation-based mesh deformation method. The full-body domain includes the near VF region, the vocal tract, a simplified model of the soft palate and mouth, and extends out into the acoustic far-field. A new kind of inflow boundary condition based upon a quasi-one-dimensional formulation with constant sub-glottal volume velocity, which is linked to the VF movement, has been adopted. The sound pressure levels (SPL) measured are realistic and we analyze their connection to the VF dynamics and glottal and vocal tract geometries.

description: Process models generated through process mining depict the as-is state of a process. Through annotations with metrics such as the frequency or duration of activities, these models provide generic information to the process analyst. To improve business processes with respect to performance measures, process analysts require further guidance from the process model. In this study, we design Graph Relevance Miner (GRM), a technique based on graph neural networks, to determine the relevance scores for process activities with respect to performance measures. Annotating process models with such relevance scores facilitates a problem-focused analysis of the business process, placing these problems at the centre of the analysis. We quantitatively evaluate the predictive quality of our technique using four datasets from different domains, to demonstrate the faithfulness of the relevance scores. Furthermore, we present the results of a case study, which highlight the utility of the technique for organisations. Our work has important implications both for research and business applications, because process model-based analyses feature shortcomings that need to be urgently addressed to realise successful process mining at an enterprise level.

description: The aim of the article was to identify certain relationships between international trade and food security with special emphasis on regional trade agreements. The study was conducted on the basis of domestic and foreign sources of literature. Unresolved problem of food insecurity indicate not only identification of the source of this state , but also ways to improve the food situation in the world. One of the factors that improve directly and indirectly food security level is international trade. Limited capability for performing trade liberalization at the global level means that the way of improving access to food is regionalism. However, taking full advantage of regional trade agreements to solve the problem of food insecurity must be accompanied by elimination or reduction the non-tariff barriers, that still exist.

description: The aim of the study is to investigate the dynamic relationship between agro-food exports and production of agricultural sectors of EU countries in the period of 1994-2011. In the sake of accessing the degree of the interdependency between researched factors the time series techniques were employed. The first stage of the analysis was the assessment of the modeling process formal condition – the examination of variables stationarity. Because the stationarity hypothesis was rejected, the variables were differentiated to achieve stationarity. Subsequently, considered relationship was quantified by the mean of dynamic panel model. The model parameters suggest considerable impact of agro-food exports as immediate factor stimulating agricultural production among EU countries.

description: There has been substantial progress in recent years in the quantitative understanding of the nonequilibrium time evolution of quantum fields. Important topical applications, in particular in high energy particle physics and cosmology, involve dynamics of quantum fields far away from the ground state or thermal equilibrium. In these cases, standard approaches based on small deviations from equilibrium, or on a sufficient homogeneity in time underlying kinetic descriptions, are not applicable. A particular challenge is to connect the far-from-equilibrium dynamics at early times with the approach to thermal equilibrium at late times. Understanding the ``link'' between the early- and the late-time behavior of quantum fields is crucial for a wide range of phenomena. For the first time questions such as the explosive particle production at the end of the inflationary universe, including the subsequent process of thermalization, can be addressed in quantum field theory from first principles. The progress in this field is based on efficient functional integral techniques, so-called n-particle irreducible effective actions, for which powerful nonperturbative approximation schemes are available. Here we give an introduction to these techniques and show how they can be applied in practice. Though we focus on particle physics and cosmology applications, we emphasize that these techniques can be equally applied to other nonequilibrium phenomena in complex many body systems.

description: The late 1980s witnessed a process of a radical re-design and re-launch of a large European market, a process that Joseph Schumpter would probably not have hesitated calling "creative destruction." The challenge of the "Europe 1992" process is a fascinating but very demanding mixture of static and dynamic efficiency, which invests the market together with the institutions that regulate the market. While the static efficiency comes about from the tearing down of trade barriers, it is in the internal market that an increase in dynamic efficiency comes about with competitive pressure that induces innovation in products and processes. The author focuses attention on the efficiency benefits of dynamic and innovative renovation, placing the European industrial system and its internal and international integration at the centre.

description: O contingenciamento da importação de fertilizantes tem sido a política adotada por mais longo tempo no Brasil. A principal razão para adoção do contingenciamento, tem sido a necessidade de reservar uma parte de mercado para a indústria nacional de fertilizantes. O fato de que o uso de fertilizantes no Brasil varia de região para região, induz a que as importações autorizadas a base de contingenciamento também variem entre regiões. Isto possibilita que importações autorizadas numa região sejam usadas noutras, alterando a relação de preços por mais esta via. Os resultados da presente análise, evidenciam como proteção da indústria nacional onera os custos do setor agrícola, impondo-lhe uma série de ineficiências no uso dos recursos. Algumas das conclusões aqui alcançadas mostram que preços subsidiados aos agricultores têm o efeito de compensar imperfeições criadas por mecanismos como o contingenciamento de importações.

description: Holzleichtbeton ist ein Verbundwerkstoff aus Zement, Holzspänen, Wasser und Mineralisierungsadditiven, aus dem plattenförmige Bauteile erzeugt werden. In den Produktgruppen wie Mantelbetonsteine oder Systembauteile ist das Material in Österreich weitgehend bekannt, die größere Palette an vorgefertigten Platten für den Fassaden- und Innenbereich ist dagegen kaum verbreitet. Die wirtschaftlichen Studien beziehen sich auf Herstellungsprozesse, Einsatzgebiete, Verarbeitungsmöglichkeiten, Transport, Materialpreise und Entsorgung von vorgefertigten Holzleichtbetonplatten. Referenz- und Anwendungsdetails verschiedener Anbieter zeigen auf, wie die Platten eingesetzt und verarbeitet werden. Die Möglichkeiten für dieses umweltfreundliche, leicht verarbeitbare, leistungsfähige und gestaltbare Material werden im Vergleich zu anderen Baustoffen untersucht und kritisch betrachtet. Dabei konnte herausgefunden werden, dass Holzleichtbeton für sichtoffene wie für Unterkonstruktionen eine leistungsfähige und günstige Alternative ist, die noch nicht am Ende ihrer Möglichkeiten ist.
description: Wood lightweight concrete is a composite material made of cement, wood chips, water and mineralized additives, from which plate-shaped components are produced. In the product groups such as cladding concrete blocks or system components, the material in Austria is well known, the greater range of prefabricated panels for facades and interior, however, is not widespread. The economic studies relates to manufacturing processes, areas of application, processing facilities, transportation, material prices and disposal of prefabricated wooden lightweight concrete panels. References and application details from different vendors show how the plates are used and processed. The possibilities for this environment friendly, easy to process, powerful and customizable material are examined and critically contemplated in comparison to other building materials. It could be found that wood lightweight concrete for exposed uses as for substructures is a powerful and cost-effective alternative, which is not yet at the end of its possibilities.

description: To quantify the fate of respiratory droplets under different ambient relative humidities, direct numerical simulations of a typical respiratory event are performed. We found that, because small droplets (with initial diameter of 10um) are swept by turbulent eddies in the expelled humid puff, their lifetime gets extended by a factor of more than 30 times as compared to what is suggested by the classical picture by William F. Wells, for 50% relative humidity. With increasing ambient relative humidity the extension of the lifetimes of the small droplets further increases and goes up to around 150 times for 90% relative humidity, implying more than two meters advection range of the respiratory droplets within one second. Employing Lagrangian statistics, we demonstrate that the turbulent humid respiratory puff engulfs the small droplets, leading to many orders of magnitude increase in their lifetimes, implying that they can be transported much further during the respiratory events than the large ones. Our findings provide the starting points for larger parameter studies and may be instructive for developing strategies on optimizing ventilation and indoor humidity control. Such strategies are key in mitigating the COVID-19 pandemic in the present autumn and upcoming winter.

description: We present a detailed study of the kinetic cluster growth process during gelation of weakly attractive colloidal particles by means of experiments on critical Casimir attractive colloidal systems, simulations and analytical theory. In the experiments and simulations, we follow the mean coordination number of the particles during the growth of clusters to identify an attractive-strength independent cluster evolution as a function of mean coordination number. We relate this cluster evolution to the kinetic attachment and detachment rates of particles and particle clusters. We find that single-particle detachment dominates in the relevant weak attractive-strength regime, while association rates are almost independent of the cluster size. Using the limit of single-particle dissociation and size-independent association rates, we solve the master kinetic equation of cluster growth analytically to predict power-law cluster mass distributions with exponents $-3/2$ and $-5/2$ before and after gelation, respectively, which are consistent with the experimental and simulation data. These results suggest that the observed critical Casimir-induced gelation is a second-order nonequilibrium phase transition (with broken detailed balance). Consistent with this scenario, the size of the largest cluster is observed to diverge with power-law exponent according to three-dimensional percolation upon approaching the critical mean coordination number.
title: Sustainable Low-Carbon Isolated Island Electricity Systems - Policy and Investment Impacts Assessed Using System Dynamics
Creators: name: Matthew, George Jr. Shaundel
Publisher: name: The Open University
Year: 2017

description: This thesis presents a novel System Dynamics (SD) policy and investment analysis framework for future low-carbon electricity systems, using an electrically isolated island system as its case study. Current electricity systems are undergoing a long-term transition towards reduced fossil fuel use, primarily driven by high fuel costs, environmental concerns and the desire for energy security. These systems are facing a number of evolving policy drivers: most notably, current attempts to pursue higher levels of renewable energy sources, greater energy efficiency and other supporting technologies. Emerging challenges are shaping the low-carbon objectives of future electricity systems and the ensuing implications for future policy and investment decisions. This thesis presents a number of critical policy recommendations allied with longer-term investment observations, evolving from the nexus between the environmental and energy security concerns of an island-based electricity system. Island systems such as São Miguel, are small enough to be understood while being large enough to reveal highly complex structures and inherent time and spatial interactions within and between social, economic and technical factors. It is argued that a systematic SD-based approach can reveal possible system structure trajectories, with such insights assisting the understanding of overall sustainability while recognising emergent challenges and behaviours. The thesis shows that learning-by-doing renewables cost reductions exists but are not very significant in island electricity systems. Additionally, it shows that setting low-carbon policy targets is beneficial for emissions reductions, but meeting these targets too early is either inefficient or impractical if targets are unrealistic. Critical evaluations of endogenous electricity demand growth and the system capacity margin are provided, which highlights consequential policy challenges for island-based systems. The most important and influential low-carbon agendas giving endogenous impacts on electricity demand are elaborated. The thesis also confirms that more effective policies, for sustained renewables uptake and improved investor decision-making for the generation mix, can be achieved. Insights distilled from smaller electricity systems can help frame the outlook of larger systems.

description: We consider a novel class of Weyl-conformally invariant p-brane theories which describe intrinsically light-like branes for any odd world-volume dimension, hence the acronym WILL-branes (Weyl-Invariant Light-Like branes). We discuss in some detail the properties of WILL-brane dynamics which significantly differs from ordinary Nambu-Goto brane dynamics. We provide explicit solutions of WILL-membrane (i.e., p=2) equations of motion in arbitrary D=4 spherically symmetric static gravitational backgrounds, as well as in product spaces of interest in Kaluza-Klein context. In the first case we find that the WILL-membrane materializes the event horizon of the corresponding black hole solutions, thus providing an explicit dynamical realization of the membrane paradigm in black hole physics. In the second "Kaluza-Klein" context we find solutions describing WILL-branes wrapped around the internal (compact) dimensions and moving as a whole with the speed of light in the non-compact (space-time) dimensions.

description: We present a systematic investigation of jet production at hadron colliders from a phenomenological point of view, with the dual aim of providing a validation of theoretical calculations and guidance to future determinations of parton distributions (PDFs). We account for all available inclusive jet and dijet production measurements from ATLAS and CMS at 7 and 8 TeV by including them in a global PDF determination, and comparing to theoretical predictions at NNLO QCD supplemented by electroweak (EW) corrections. We assess the compatibility of the PDFs, specifically the gluon, obtained before and after inclusion of the jet data. We compare the single-inclusive jet and dijet observables in terms of perturbative behaviour upon inclusion of QCD and EW corrections, impact on the PDFs, and global fit quality. In the single-inclusive case, we also investigate the role played by different scale choices and the stability of the results upon changes in modelling of the correlated experimental systematics.

description: O objetivo central deste trabalho é o de determinar o impacto do reflorestamento e de outra atividade competitiva em terra, representada pela pecuária de corte, na geração de divisas para o país. Utilizou-se a metodologia da taxa de câmbio de Bruno-Kreuger e do custo social de divisas. Os resultados encontrados mostraram que ambas as atividades são interessantes como geradoras de divisas, sendo o reflorestamento, no entanto, comparativamente mais valioso.
Liberalizzazione valutaria e sostituibilità tra monete

Subjects: subject: Italy, lira, banking system, liberalisation, currency substitution
subject: F31

description: The economic effects of planned liberalisation measures have led to considerable debate in Italy, especially regarding the possibility that, in the absence of administrative barriers, a large transfer of monetary capital in favour of foreign assets takes place, resulting in the disintermediation of the Italian banking system and or the Italian lira. In this paper, the authors propose a method to estimate this phenomenon, taking as reference the scientific literature that has addressed the issue of the substitution between currencies. An initial analysis of the contributions to this theme provides specificity from a theoretical point of view on the circumstances that make currency substitution possible, and provides methodological guidance for the empirical survey that follows.

description: The need for cables with high-fidelity Virtual Reality (VR) headsets remains a stumbling block on the path towards interactive multi-user VR. Due to strict latency constraints, designing fully wireless headsets is challenging, with the few commercially available solutions being expensive. These solutions use proprietary millimeter wave (mmWave) communications technologies, as extremely high frequencies are needed to meet the throughput and latency requirements of VR applications. In this work, we investigate whether such a system could be built using specification-compliant IEEE 802.11ad hardware, which would significantly reduce the cost of wireless mmWave VR solutions. We present a theoretical framework to calculate attainable live VR video bitrates for different IEEE 802.11ad channel access methods, using 1 or more head-mounted displays connected to a single Access Point (AP). Using the ns-3 simulator, we validate our theoretical framework, and demonstrate that a properly configured IEEE 802.11ad AP can support at least 8 headsets receiving a 4K video stream for each eye, with transmission latency under 1 millisecond.

description: O objetivo deste trabalho é estimar os efeitos do ICM sobre os setores algodoeiros dos estados do Paraná e de São Paulo. Os resultados indicam que na ausência da incidência do ICM, com alíquota de 15 por cento, a produção de algodão nos estados de São Paulo e do Paraná teria aumentado em 107,8 mil toneladas, equivalente a um acréscimo de 17 por cento. Sob a pressuposição de uma economia aberta, esta quantidade representaria uma redução na exportação e na receita de exportação em relação ao que poderia ser alcançado. A retirada do ICM no Estado de São Paulo representou ganhos consideráveis aos produtores deste estado, além da eliminação do custo social e do aumento da renda de exportação. No Estado do Paraná, a continuidade da incidência do ICM resultou em redução na renda dos produtores.

description: This document constitutes the “AQUARIUS Communication and Dissemination Plan I” as Deliverable 7.1 and details the approach to and implementation of AQUARIUS communication and dissemination activities. The plan is designed to maximise the impact of AQUARIUS activities across all Work Packages, in particular, through raising awareness, mobilising engagement and promoting uptake of AQUARIUS results with target stakeholder groups. The approach to this plan considers the objectives (why), target stakeholder groups (who), key messages (what), timing and phases (when), tools and materials (how), main channels (where), together with key performance indicators. It includes a preliminary calendar of activities for the current period (M1-M18), which will be updated regularly.This plan will be reviewed for efficacy and updated by month 18 as “AQUARIUS Communication and Dissemination Plan II”.

subject: FOS: Physical sciences

description: The physical states of N=4 conformal supergravity in four dimensions occur in twistor-string theory by Berkovits and Witten(hep-th/0406051). We study two alternative versions of twistor-string theory based on the B-model of weighted projective space WCP^{3|2} and based on a certain construction involving open strings. The spacetime fields described by the twistor superfields contain the physical states of N=1 conformal supergravity from above N=4 superspace approach.

A FARINHA DE MANDIOCA E A INDUSTRIALIZAÇÃO RURAL: UMA ANÁLISE ECONÔMICA E SOCIAL

Year: 1979
Subjects: Agribusiness

description: Este estudo possui um duplo objetivo: 1. Analisar comparativamente as estruturas de produção e de remuneração entre os três tipos de casas de farinha no Ceará: a) primitivas (totalmente manual); b) as que utilizam os motores a gasolina; c) as que utilizam os motores elétricos; 2. Comparar este tipo de indústria rural existente no Ceará com aquele considerado urbano no Estado de São Paulo (intensivos em capital) a fim de se determinar os custos e os benefícios de se investir na produção de farinha em unidades de grande escala no interior do Ceará. Os principais resultados alcançados são: a) A casa de farinha que utiliza de motor elétrico possui as taxas mais elevadas de salários, produtividade e lucro. b) Os sacrifícios sociais impostos pela produção de farinha de mandioca através de uma unidade produtiva intensiva em capital e em grande escala (medidos através da elaboração na taxa de desemprego rural e a redução no consumo de farinha de mandioca) são, certamente fundamentais e, portanto, merecem uma atenção maior, atribuindo-se pesos ideais contra os benefícios econômicos ao se avaliar um projeto desta natureza.

Curiouser and curiouser! Exploring the narratives and consequences of panhandling regulation in British Columbia
Creators: name: Lawrence-Anand, April Katherine
Publisher: name: University of British Columbia
Year: 2011

description: In 2004 the British Columbia legislature passed the Safe Streets and Trespass Amendment Acts. The Downtown Vancouver Business Improvement Association (DVBIA) credits its lobbying process as having convinced the government to do so. The DVBIA is an unusual Business Improvement Association (BIA) as its advocacy mandate concerns extra-economic issues and its resources vastly exceed those of other BIAs in Vancouver. This thesis explores its advocacy position and the consequences of the legislation. The lobby process is treated as one of narrative creation, with some attention to how the DVBIA's resources influenced its success. Broken Windows Theory is used to explain the DVBI A's presentation of panhandling and trespass as elective activities, separate from any conception of need. The DVBIA's narrative must construct these actions as optional before they can be rendered criminal. A Critical Discourse Analysis (CDA) is used to explore both why the DVBIA successfully generated support for the legislation, and why the opponents of the legislation were unsuccessful. The CDA reveals that the DVBIA had access to narratives - such as poverty as the fault of the individual, the competitive city or security - that are connected directly to contemporary society. These narratives allow for simple stories of blame and reform, tidily creating the 'problem' and the 'solution'. These simple narratives are easily communicated through sound-bite media. The' opponents of the legislation had access only to narratives such as fairness, generalized poverty, compassion or civil liberties. These narratives have complicated explanations of panhandling's root causes, offer no simple solutions and were ineffective in countering the DVBIA's simple problem constructions. An analysis of the legislation examines its consequence for an actively political public space, citizenship and rights as well as the penalties for violation of the Acts. The consequences advocated by the DVBIA, arrest and area restrictions, are discussed in terms of the principle of legal proportionality and theories of what punishment is to accomplish. The analysis is finally framed in terms of Mill's Harm Principle to discuss how the Safe Streets Act incorrectly legislates panhandling as a harm and as an offence worthy of legal consequence.
