description: This paper draws on perspectives from co-design as an integrative and collaborative design activity and co-simulation as a supporting information system to advance engineering design methods for problems of societal significance. Design and implementation of the Sustainable Infrastructure Planning Game provides a prototypical co-design artifact that leverages the High Level Architecture co-simulation standard. Three role players create a strategic infrastructure plan for agriculture, water, and energy sectors to meet sustainability objectives for a growing and urbaninzing population in a fictional desert nation. An observational study conducts 15 co-design sessions to understand underlying dynamics between actors and how co-simulation capabilities influence design outcomes. Results characterize the dependencies and conflicts between player roles based on technical exchange of resource flows, identifying tension between agriculture and water roles based on water demands for irrigation. Analysis shows a correlation between data exchange, facilitated by synchronous co-simulation, and highly-ranked achievement of joint sustainability outcomes. Conclusions reflect on the opportunities and challenges presented by co-simulation in co-design settings to address engineering systems problems.

description: An infrared study of the phonon spectra of ZrW2O8 as a function of temperature which includes the low energy (2-10 meV) region relevant to negative thermal expansion is reported and discussed in the context of specific heat and neutron density of states results. The prevalence of infrared active phonons at low energy and their observed temperature dependence are highly unusual and indicative of exotic low-energy lattice dynamics. Eigenvector calculations indicate a mixing of librational and translational motion within each low-frequency IR mode. The role of the underconstrained structure in establishing the nature of these modes, and the relationship between the IR spectra and the large negative thermal expansion in ZrW2O8 are discussed.

Indipendenza della banca centrale, vigilanza bancaria e stabilita monetaria

Publisher: name: Moneta e Credito
Year: 2013
Subjects: subject: Central bank independence, banking system, monetary stability
subject: E58

description: The overall conclusion of recent macroeconomic literature is that the existence of an independent central bank, which is responsible for monetary stability and increases monetary controls, in the long-term favours a non-inflationary trend in monetary aggregates, without creating negative repercussions on fiscal and real aggregates. The main limitation of this approach is that it does not examine in-depth the analysis of the interactions between the central bank and the banking system, if not considering the latter a passive transmission box of monetary policy. This paper, starting from a general interpretation of the theoretical results related to the relationship between central bank independence and monetary stability - in terms of objectives and instruments - aims to provide an initial contribution on the subject, in terms of theory and on that of comparative institutional analysis.

A Note on BIBO Stability

Publisher: name: arXiv
Year: 2020
Subjects: subject: Functional Analysis (math.FA)
subject: FOS: Mathematics

description: The statements on the BIBO stability of continuous-time convolution systems found in engineering textbooks are often either too vague (because of lack of hypotheses) or mathematically incorrect. What is more troubling is that they usually exclude the identity operator. The purpose of this note is to clarify the issue while presenting some fixes. In particular, we show that a linear shift-invariant system is BIBO-stable in the $L_\infty$-sense if and only if its impulse response is included in the space of bounded Radon measures, which is a superset of $L_1(\mathbb{R})$ (Lebesgue's space of absolutely integrable functions). As we restrict the scope of this characterization to the convolution operators whose impulse response is a measurable function, we recover the classical statement.

description: This paper analyses the concept of Self-Sovereign Identity (SSI), an emerging approach for establishing digital identity, in the context of the Internet of Things (IoT). We contrast existing approaches for identity on the Internet, such as cloud-based accounts and digital certificates, with SSI standards such as Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). To the best of our knowledge, this is the first thorough comparison of these approaches. The benefits and challenges of using DIDs and VCs to identify and authenticate IoT devices and their respective users are discussed. In the end, we establish that SSI, with its owner-centric, privacy-aware and decentrailized approach, provides a viable and attractive option for secure identification of IoT devices and users.
Crescita endogena, fluttuazioni cicliche e accumulazione del capitale

Subjects: subject: Growth models, Asymmetric information
subject: E10

description: The work aims to remedy the shortcomings of previous growth models by examining imperfect information and financial constraints in a New Keynesian setting. Capital-market imperfections and related information asymmetries induce agents to be risk averse, and give rise to the net worth of firms and banks. Asymmetric information binds together banks’ lending and firms’ borrowing, effecting the aggregate amount of production and investment and potentially causing instability. The authors theorise that this effect on financial constraints is large and persistent enough to constitute an endogenous determination of cyclical fluctuations as well as of trend. JEL Codes: E10

Newtonian Fractional-Dimension Gravity and Disk Galaxies

description: This paper continues previous work on a novel alternative model of gravity, based on the theory of fractional-dimension spaces applied to Newton's law of gravitation. In particular, our Newtonian Fractional-Dimension Gravity is now applied to axially-symmetric structures, such as thin/thick disk galaxies described by exponential, Kuzmin, or other similar mass distributions. As in the case of spherically-symmetric structures, which was studied in previous work on the subject, we examine a possible connection between our model and Modified Newtonian Dynamics, a leading alternative gravity model, which accounts for the observed properties of galaxies and other astrophysical structures without requiring the dark matter hypothesis. By relating the MOND acceleration constant $a_{0} \simeq 1.2 \times 10^{ -10}\mbox{m}\thinspace \mbox{s}^{ -2}$ to a natural scale length $l_{0}$ of our model, namely $a_{0} \approx GM/l_{0}^{2}$ for a galaxy of mass $M$, and by using the empirical Radial Acceleration Relation, we are able to explain the connection between the observed radial acceleration $g_{obs}$ and the baryonic radial acceleration $g_{bar}$ in terms of a variable local dimension $D$. As an example of this methodology, we provide a detailed rotation curve fitting for the case of the field dwarf spiral galaxy NGC 6503.

description: Gaia Data Release 2 revealed detailed structures of nearby stars in phase space. These include the Hercules stream, whose origin is still debated. Most of the previous numerical studies conjectured that the observed structures originate from orbits in resonance with the bar, based on static potential models for the Milky Way. We, in contrast, approach the problem via a self-consistent, dynamic, and morphologically well-resolved model, namely a full $N$-body simulation of the Milky Way. Our simulation comprises about 5.1 billion particles in the galactic stellar bulge, bar, disk, and dark-matter halo and is evolved to 10 Gyr. Our model's disk component is composed of 200 million particles, and its simulation snapshots are stored every 10 Myr, enabling us to resolve and classify resonant orbits of representative samples of stars. After choosing the Sun's position in the simulation, we compare the distribution of stars in its neighborhood with Gaia's astrometric data, thereby establishing the role of identified resonantly trapped stars in the formation of Hercules-like structures. From our orbital spectral-analysis we identify multiple, especially higher order resonances. Our results suggest that the Hercules stream is dominated by the 4:1 and 5:1 outer Lindblad and corotation resonances. In total, this yields a trimodal structure of the Hercules stream. From the relation between resonances and ridges in phase space, our model favored a slow pattern speed of the Milky-Way bar (40--45 $\mathrm{km \; s^{-1} \; kpc^{-1}}$).

description: Abstract:- Now a days XML is becoming a standard in data representation and data exchanging. Due to its simplicity and lightweight most of the real time applications adopted XML as a DB to store the frequently updating enterprise data, which have complex schema and design with thousands of xml elements. To retrieve the data from XML databases effectively, most previous information retrieval(IR) approaches used XQuery and XSEarch, which are schema and design based mechanisms and allows only the DB experts for querying data. Lack of knowledge on the database schema and design can be a significant obstacle for common users who want to access the information in an XML database.Inspired by the great success of information retrieval (IR) style keyword search on the web, keyword search on XML has emerged recently, which is schema independent approach and allows all the user to query XML databases by using keyword combination without the knowledge of complex query languages and the database schema. In this paper we propose the Schema and Design Free Keyword search Interfaces (SDFKI) to address the above dependency problems and achieves the higher result relevance and scalability. SDFKI not only return relevant results, it will overcome the data redundancy problem in XML databases and uses a novel XRank ranking strategy to display the results in ranked order. Lastly extensive experiments have been conducted to show the effectiveness of our approach.

The decay properties of sneutrinos can be used to obtain information about the relative importance of these couplings provided sneutrinos are the lightest supersymmetric particles. We show that in some specific scenarios it is even possible to decide whether bilinear or trilinear terms give the dominant contribution to the neutrino mass matrix.

description: We consider the critical behavior of the most general system of two N-vector order parameters that is O(N) invariant. We show that it may a have a multicritical transition with enlarged symmetry controlled by the chiral O(2)xO(N) fixed point. For N=2, 3, 4, if the system is also invariant under the exchange of the two order parameters and under independent parity transformations, one may observe a critical transition controlled by a fixed point belonging to the mn model. Also in this case there is a symmetry enlargement at the transition, the symmetry being [SO(N)+SO(N)]xC_2, where C_2 is the symmetry group of the square.

description: In der an der Sonnenküste Südspaniens liegenden Gemeinde Nerja beinfiden sich sechs Wach- (torres vigía) sowie Wehrtürme aus dem XVI bis XVIII Jahrhundert welche unter Denkmalschutz stehen. Diese Wachtürme sind Teil eines visuell verbundenen Turmsystems wie es zur Kontrolle der Meeresküste üblich war. Die Türme sind an exponierten Lagen positioniert damit deren Wächter den Alarm schnellstmöglich weitergeben konnten. Während meines Auslandsstudienjahres in Südspanien habe ich die Region um Nerja besser kennen gelernt. Die Türme welche entlang der Küste allgegenwärtig sind, prägen die Region und geben ihr einen besonderen Charakter. Nerja weist aufgrund seiner stark zerklüfteten Küste mit zahlreichen Buchten in einer Länge von etwa 13km eine Vielzahl an Türmen auf. Nach zahlreichen Gesprächen mit den Bewohnern aus der Region, welche oft wenig über die Geschichte der Türme zu berichten hatten, entstand die Idee zu diesem Projekt. Diese Arbeit beschäftigt sich mit der Planung eines Besucherzentrums welches Informationen für Besucher sowie Einheimische bietet und sich mit der Geschichte Nerjas und der Region auseinandersetzt. Als Standort bietet sich ein öffentlicher Bereich direkt angrenzend an die Ruine des einzigen im Stadtgefüge Nerjas platzierten Turmes "Torrecilla de Nerja" aus dem 18.Jahrhundert.
description: In southern spain in the community of Nerja we find six watchtowers (torres vigía) from the 16.-18.century which are listed buildings. These watchtowers are part of a visually connected tower system as it has been customary to control the coast. These towers are positioned in exposed locations so their guards could transmit the alarm as quick as possible. During my academic year in southern Spain I have got to know the region around Nerja. The towers which along the coast are omnipresent, give a special character to the region. Because of its very rugged coast with numerous bays in a length of 13km, Nerja owns a huge number of towers. After numerous talks with the inhabitants from the region, who had little to tell about the history of the towers, developed the idea to this project. This work deals with the planning of a visitor center which offers information for visitors as well as locals. It informs about the history of the region. The location is a public area adjacent to the ruins of the only tower placed in the urbanization of nerja town "Torrecilla de Nerja" which is from the 18th century.
Una nota sulla filosofia sociale di Keynes

description: Keynes attitude, not only in General Theory but also throughout the whole of his intellectual career, is essentially that of making economic theory useful and in particular making it applicable to the problem of eliminating the shortcomings of contemporary economic systems. Keynes’ formulation of the general macroeconomic equilibrium was proceeded over the years by a broader reflection on the nature of the capitalistic economic system, the individual motivations that sustain it and its ethical aspects in comparison to other systems. However, there is almost no trace of this in General Theory, if not only partially in the last chapter of the book. To rebuild these aspects we must refer to a relatively neglected group of essays from 1925 to 1928 that concern the nature of the capitalist system more broadly. The reconstruction of Keynes's thinking on these issues is not only important in itself in order to a better understand the ideas of this century's greatest economist, it is also a contribution understanding the enduring relevant problems and questions that today call for reflection on behalf of economists and politicians.

description: In the Digital Age, the use of Big Data analytics has increasingly become a central topic of debate for policy-makers, legislators and international institutions. The GDPR –– with its rights-based approach –– aims to provide individuals with adequate protection against the threats associated to big data. However, under Article 23 of the Regulation, Member States are allowed to derogate and restrict fundamental rights as long as they represent proportional and necessary measures. In light of the current campaign led by Open Rights Group and the3million, this report argues that the UK government, through the use of data analytics, and considering a history of xenophobic implementations of immigration and criminal law, has unrightfully applied an immigration exemption in the current 2018 DPA. In order to validate this claim, this report considers how three other EU Member States –– Italy, France and Germany –– have handled derogations under Article 23, but to very different ends.

description: The aim of the work is to interpret recent topics of discussion related to the theory of exchange rates, taking into account the conclusions of the theoretical research on financial and currency markets. The author suggests that the setup of the analysis of financial markets should be reconsidered to focus on the elements of inertia and uncertainty in the behaviour of economic agents, factors that are capable of distancing currency markets from efficient conditions. Highlighting the existing empirical and theoretical principals, the author first considers the various reasons for the compatibility of rationality with the distortion of expectations and then the characteristics of the models of the formation of expectations regarding the nature of speculation. A fundamental component of short-term dynamics is identified in "chartism", for which the theoretical reasons are discussed. JEL Codes: D51

description: This paper provides an extended exploration of the inverse-chirp gravitational-wave signals from stellar collapse in massive scalar-tensor gravity reported in [Phys. Rev. Lett. {\bf 119}, 201103]. We systematically explore the parameter space that characterizes the progenitor stars, the equation of state and the scalar-tensor theory of the core collapse events. We identify a remarkably simple and straightforward classification scheme of the resulting collapse events. For any given set of parameters, the collapse leads to one of three end states, a weakly scalarized neutron star, a strongly scalarized neutron star or a black hole, possibly formed in multiple stages. The latter two end states can lead to strong gravitational-wave signals that may be detectable in present continuous-wave searches with ground-based detectors. We identify a very sharp boundary in the parameter space that separates events with strong gravitational-wave emission from those with negligible radiation.

O objetivo deste trabalho é uma investigação acerca do comportamento de um conjunto de práticas agrícolas, com respeito a lucro e risco. Foi utilizada a técnica de dominância estocástica, para a seleção das alternativas com possibilidades de serem escolhidas por agricultores avessos ao risco. De um modo geral, dentro das restrições apresentadas pelos dados empregados, nota-se, que grandes aumentos no preço do milho não contribuem para maior uso de híbridos ao invés de variedades, o que tornaria possível ganhos, em termos de lucro, apenas com o aumento da população de plantas. O uso de maior quantidade de adubo está vinculado à utilização de híbridos e de uma população maior do que a usualmente empregada.

description: In Viticulture, visual inspection of the plant is a necessary task for measuring relevant variables. In many cases, these visual inspections are susceptible to automation through computer vision methods. Bud detection is one such visual task, central for the measurement of important variables such as: measurement of bud sunlight exposure, autonomous pruning, bud counting, type-of-bud classification, bud geometric characterization, internode length, bud area, and bud development stage, among others. This paper presents a computer method for grapevine bud detection based on a Fully Convolutional Networks MobileNet architecture (FCN-MN). To validate its performance, this architecture was compared in the detection task with a strong method for bud detection, Scanning Windows (SW) based on a patch classifier, showing improvements over three aspects of detection: segmentation, correspondence identification and localization. The best version of FCN-MN showed a detection F1-measure of $88.6\%$ (for true positives defined as detected components whose intersection-over-union with the true bud is above $0.5$), and false positives that are small and near the true bud. Splits -- false positives overlapping the true bud -- showed a mean segmentation precision of $89.3\% (21.7)$, while false alarms -- false positives not overlapping the true bud -- showed a mean pixel area of only $8\%$ the area of a true bud, and a distance (between mass centers) of $1.1$ true bud diameters. The paper concludes by discussing how these results for FCN-MN would produce sufficiently accurate measurements of bud variables such as bud number, bud area, and internode length, suggesting a good performance in a practical setup.

description: The spectra of helium-dominated white dwarf stars with hydrogen in their atmosphere present a distinctive broad feature centered around 1160~Å\/ in the blue wing of the Lyman-$α$ line. It is extremely apparent in WD 1425+540 recently observed with HST COS. With new theoretical line profiles based on ab initio atomic interaction potentials we show that this feature is a signature of a collision-induced satellite due to an asymptotically forbidden transition. This quasi-molecular spectral satellite is crucial to understanding the asymmetrical shape of Lyman-$α$ seen in this and other white dwarf spectra. Our previous work predicting this absorption feature was limited by molecular potentials that were not adequate to follow the atomic interactions with spectroscopic precision to the asymptotic limit of large separation. A new set of potential energy curves and electronic dipole transition moments for the lowest electronic states of the H--He system were developed to account accurately for the behavior of the atomic interactions at all distances, from the chemical regime within 1~Å\/ out to where the radiating H atoms are not significantly perturbed by their neighbors. We use a general unified theory of collision-broadened atomic spectral lines to describe a rigorous treatment of hydrogen Lyman-$α$ with these potentials and present a new study of its broadening by radiative collisions of hydrogen and neutral helium. These results enable ab initio modeling of radiative transport in DBA white dwarf atmospheres.

description: Band structures for solid rare gases (Ne, Ar) have been calculated using the GW approximation. All electron and pseudopotential ab initio calculations were performed using Gaussian orbital basis sets and the dependence of particle-hole gaps and electron affinities on basis set and treatment of core electrons is investigated. All electron GW calculations have a smaller particle-hole gap than pseudopotential GW calculations by up to 0.2 eV. Quasiparticle electron and hole excitation energies, valence band widths and electron affinities are generally in very good agreement with those derived from optical absorption and photoemission measurements.

Modification of red cell antigenic characteristics via covalent modification with branched poly (ethylene glycol)
Creators: name: Srubiski, Aviva
Publisher: name: University of British Columbia
Year: 2011

description: Background: Red Blood Cell (RBC) transfusions are associated with the risk of rejection and sensitization for the recipient. Covalent modification of human RBC using poly (ethylene glycol)) (PEG) is currently being investigated as a method to modify the antigenic characteristics of RBC in order to develop an antigenically silent RBC transfusion product. The focus of this study is to determine whether a branched PEG, 4PEGss [MW 10,000] can concurrently camouflage and stabilize the RBC membrane, giving the red cell higher osmotic resistance. Study Design and Methods: Human blood was collected from consenting donors into EDTA tubes. RBC were separated, counted, washed and incubated with 4PEGss stock solution for up to 120 minutes at room temperature (RT). Agglutination assays and flow cytometry were used to determine polymer-dependent antigen masking while scanning electron microscopy (SEM), erythrocyte sedimentation rate (ESR) assays, osmotic fragility assays, hemolysis measurements and generation of hemoglobin oxidation species were used to measure the impact of 4PEGss treatment on RBC function. Results: Agglutination assays and flow cytometry showed that 4PEGss treatment significantly camouflaged RhD and A and B antigens in a dose-dependent manner. However, SEM and ESR assays indicated 4PEGss treatment may cause cell aggregate formation. Osmotic fragility assays and hemolysis measurements showed a 4PEGss-mediated increase of hemolysis. Conclusions: At all concentrations investigated, 4PEGss modification yielded antigenically camouflaged (both ABO and RhD) yet less stable RBC compared to non-treated controls.

description: The goals of multilateral trade negotiations under the auspices of the General Agreement on Tariffs and Trade (the GATT) have been developed in the context of the orthodox theory of commercial policy. An analysis is offered that shows why the GATT ideal may not be a flexible medium-term goal under existing conditions. Although the argument advanced has relevance to multilateral trade negotiations generally, the specifics of the Uruguay Round are not explored. JEL Codes: F02, F40

Dalla teoria delle passioni al nuovo ordine: mercato e capitalismo in Adam Smith
Creators: name: RAFFAELLI, T.
Publisher: name: Moneta e Credito
Year: 2013
Subjects: subject: Adam Smith, political economy, capitalism
subject: B12

description: It is the paradigm of political economy as an autonomous science, distinguished from ethics and politics, that Adam Smith is considered to be the "founding father" of. However, this confinement has at time resulted in a distorted of his views with regards to the central themes of later times, making him at times to be the supporter of methodological individualism, of unconditional liaise faire and the minimal state, and of the full coherence between private and public interest. Indeed, he has been pushed out of his historical context to take on almost absurd traits. Stereotypical and anti-historical aspects of these images of Smith were often detected in the past, but only recently have they become the subject of a critique that also involves the paradigmatic character of the Smith’s work. Taking into account this extraordinary wealth of new studies, the author proposes some reasons in favour of the interpretation of Smith as the theorist of capitalism and the father of political economy.

description: The main element of sustainable development paradigm are three orders: social, economic and environmental. The social order, due to including the categories of the quality of life in sustainable development, is regarded as a primary objective, i.e. the state of functioning and behaviour of individuals which enables the existence, duration and development of the society as a whole. The study presents spatial variability of social order for rural communities of Lower Silesia voivodeship situated in south-western part of our country. Sustainable development index, which characterises social order, was used in the work. Synthetic index of social order, combining all the analysed indices, was determined for particular communities. In 2000-2010 its value decreased, indicating lack of realisation of sustainable development concept.
Observation of spontaneous self-channelling of light in air below the collapse threshold

description: We report the observation of the self-guided propagation of 120 fs, 0.56 mJ infrared radiation in air for distances greater than one meter. In contrast to the known case of filamentation, in the present experiment the laser power is lower than the collapse threshold. Therefore the counter balance between Kerr self focussing and ionization induced defocussing as the stabilizing mechanism is ruled out. Instead, we find evidences of a process in which the transversal beam distribution reshapes into a form similar to a Townes soliton. We include numerical support for this conclusion.

description: Die Diplomabeit behandelt das Thema der Beleuchtung des Obeliskbrunnens in Abstimmung mit dem Gesamtkonzept der Beleuchtung für das Schloss Schönbrunn und dessen Parkdenkmälern und Nebengebäuden. Abgesehen von gestalterischen, den Denkmalschutz berücksichtigenden und historischen Themen spielt auch die aktuelle und den Stand der Technik entsprechende Lichttechnik eine entscheidende Rolle.
description: This work deals with the illumination of the Obelisk Fountain as part of the illumination of the Schönbrunn Castle. The low amount of light in the surroundings of the Schönbrunn Area gives the possibility to realize the best illumination with a little amount of artificial light. Using small lightsources (LED and metal Halide) has the avantage, that the fountain that is mainly met by tourists during the day, doesn´t change in his kind of appearence.

A characterization of glucose-induced downregulation of the glucose dependent insulinotropic polypeptide receptor (GIPR)
Creators: name: Olver, Amy Virginia
Publisher: name: University of British Columbia
Year: 2011

description: The primary role of the incretin hormone, glucose-dependent insulinotropic polypeptide (GIP) is to potentiate the secretion of insulin in a glucose-dependent manner. In humans and rat models with type 2 diabetes, however, this action is impaired as a result of attenuated GIP receptor (GIPR) expression in the pancreatic β-cell. It has been previously reported that glucose strongly downregulates GIPR mRNA expression in rat insulinoma FNS-1 (832/13) cells and rat islets in a concentration-dependent manner. Since chronic hyperglycemia was proposed to be a primary cause for GIP resistance one objective of my studies was to attempt reversal of this process by pharmacologically lowering blood glucose. However, treatment studies on the effects of the dipeptidyl peptidase (DPIV) inhibitor P32/98 and a DPIV-resistant analogue D-Ala²-GIP on VDF and ZDF rats respectively, showed only moderate improvements in glucose homeostasis, and therefore were not appropriate models for determining the potential reversal effects of lowering blood glucose on islet GIPR expression. The mechanism for the glucose-induced GIPR downregulation is not clear; however it has been previously reported that peroxisome proliferated activated receptor a (PPARa), an important transcription factor involved in fatty acid metabolism, plays an important role. The second objective of this study therefore, was to investigate the effects of a PPARa overexpression system on GIPR expression in INS-1 (832/13) cells. Unexpectedly PPARa did not significantly upregulate our gene of interest; however these studies and others suggest that stimulation of PPARa alone is not sufficient for regulation, and thus also requires an increase in availability of PPARa's co-activator retinoid X receptor (RXR). The third objective of this thesis was to examine the regulation of GIPR in adipose tissue and to determine whether GIPR is differentially expressed in fat and pancreatic islet. Glucose concentration-dependent studies on INS-1 (832/13) β-cell lines and 3T3L1-adipocytes as well as an in vivo characterization study of lean (Fa/?) versus fatty (fa/fa) VDF rat models, collectively demonstrated a tissue-specific pattern of GIPR expression. In all, the findings of this thesis therefore prompt new questions and provide a basis for future experimentation.
