description: Using the finite volume CFD software FLUENT, one fan was studied at a given flow rate (1.5m3/min) for three different operational rotating speeds : 2,000, 2,350 and 2,700 rpm. The turbulent air flow analysis predicts the acoustic behavior of the fan. The best fan operating window, i.e. the one giving the best ratio between noise emissions and cooling performance, can then be determined. The broadband noise acoustic model is used. As the computation is steady state, a simple Multiple Reference Frame model (MRF, also known as stationary rotor approach) is used to represent the fan. This approach is able to capture the effects of the flow non-uniformity at the fan inlet together with their impact on the fan performance. Furthermore, it is not requiring a fan curve as an input to the model. When compared to the available catalog data the simulation results show promising qualitative agreement that may be used for fan design and selection purposes.

description: The Anthomyza macra group
The Anthomyza macra group comprises species with the most plesiomorphic formation of the male and female genitalia (cf. simple apex of nlum, small spines in saccus, presence of setae on medandrium (see Fig. 240), separate female S7, simple internal sclerites in the female genital chamber and curved (not twisted) apex of ventral receptacle) and therefore is considered to be the sister group to all remaining Anthomyza species (cf. ROHÁĆEK 2009 a, ROHÁĆEK et al. 2009). On the other hand, the group is also distinguished by several apomorphies: (1) very broad epandrium; (2) distally dilated gonostylus; (3) saccus of distiphallus with internal coiled strip-like sclerite; (4) very elongate spermathecae. Three Palaearctic species, viz. A. macra Czerny, 1928, A. pleuralis Czerny, 1928 and A. decolorata Roháček, 2009, and three Nearctic species, viz. A. tenuis (Loew, 1863), A. oblonga sp. nov. and A. silvatica sp. nov. are currently assigned to the group. Because of their very similar habitus and male and female genitalia, the identincation of some of these species can be difncult. This also causes problems in recognizing interrelationships of all its members, but hypotheses of the afnnities of the Nearctic species are presented in the discussions of each species below.

description: We consider $\mathcal{N}=2$ supersymmetric $\text{SU}(2)$ gauge theory with $N_f=4$ massive hypermultiplets. The duality group of this theory contains transformations acting on the UV-coupling $τ_{\text{UV}}$ as well as on the running coupling $τ$. We establish that subgroups of the duality group act separately on $τ_{\text{UV}}$ and $τ$, while a larger group acts simultaneously on $τ_{\text{UV}}$ and $τ$. For special choices of the masses, we find that the duality groups can be identified with congruence subgroups of $\text{SL}(2,\mathbb Z)$. We demonstrate that in such cases, the order parameters are instances of bimodular forms with arguments $τ$ and $τ_{\text{UV}}$. Since the UV duality group of the theory contains the triality group of outer automorphisms of the flavour symmetry $\text{SO}(8)$, the duality action gives rise to an orbit of mass configurations. Consequently, the corresponding order parameters combine to vector-valued bimodular forms with $\text{SL}(2,\mathbb Z)$ acting simultaneously on the two couplings.

description: Radio-to-TeV observations of the bright nearby (z=0.034) blazar Markarian 501 (Mrk 501), performed from December 2012 to April 2018, are used to study the emission mechanisms in its relativistic jet. We examined the multi-wavelength variability and the correlations of the light curves obtained by eight different instruments, including the First G-APD Cherenkov Telescope (FACT), observing Mrk 501 in very high-energy (VHE) gamma-rays at TeV energies. We identified individual TeV and X-ray flares and found a sub-day lag between variability in these two bands. Simultaneous TeV and X-ray variations with almost zero lag are consistent with synchrotron self-Compton (SSC) emission, where TeV photons are produced through inverse Compton scattering. The characteristic time interval of 5-25 days between TeV flares is consistent with them being driven by Lense-Thirring precession.

Furthermore, we find that in the case of a strongly focused plane wave up to 85 % of the incident light can be reflected by the dipole. Our results hold for the full spectrum of the electromagnetic interactions and have immediate implications for achieving strong coupling between a single propagating photon and a single quantum emitter.

description: With the advances in the technology of materials based on GaN, high brightness white light emitting diodes (LEDs) have flourished over the past few years and have shown to be very promising in many new illumination applications such as outdoor illumination, task and decorative lighting as well as aircraft and automobile illuminations. The objective of this paper is to investigate an active liquid cooling solution of such LEDs in an application of automotive headlights. The thermal design from device to board to system level has been carried out in this research. Air cooling and passive liquid cooling methods are investigated and excluded as unsuitable, and therefore an active liquid cooling solution is selected. Several configurations of the active liquid cooling system are studied and optimisation work has been carried out to find an optimum thermal performance.

description: We show theoretically that the magnetic ions, randomly distributed in a two-dimensional (2D) semiconductor system, can generate a ferromagnetic long-range order via the RKKY interaction. The main physical reason is the discrete (rather than continuous) symmetry of the 2D Ising model of the spin-spin interaction mediated by the spin-orbit coupling of 2D free carriers, which precludes the validity of the Mermin-Wagner theorem. Further, the analysis clearly illustrates the crucial role of the molecular field fluctuations as opposed to the mean field. The developed theoretical model describes the desired magnetization and phase-transition temperature $T_c$ in terms of a single parameter; namely, the chemical potential $μ$. Our results highlight a path way to reach the highest possible $T_c$ in a given material as well as an opportunity to control the magnetic properties externally (e.g., via a gate bias). Numerical estimations show that magnetic impurities such as Mn$^{2+}$ with spins $S=5/2$ can realize ferromagnetism with $T_c$ close to room temperature.

description: The prediction of future climate scenarios under anthropogenic forcing is critical to understand climate change and to assess the impact of potentially counter-acting technologies. Machine learning and hybrid techniques for this prediction rely on informative metrics that are sensitive to pertinent but often subtle influences. For atmospheric dynamics, a critical part of the climate system, no well established metric exists and visual inspection is currently still often used in practice. However, this "eyeball metric" cannot be used for machine learning where an algorithmic description is required. Motivated by the success of intermediate neural network activations as basis for learned metrics, e.g. in computer vision, we present a novel, self-supervised representation learning approach specifically designed for atmospheric dynamics. Our approach, called AtmoDist, trains a neural network on a simple, auxiliary task: predicting the temporal distance between elements of a randomly shuffled sequence of atmospheric fields (e.g. the components of the wind field from reanalysis or simulation). The task forces the network to learn important intrinsic aspects of the data as activations in its layers and from these hence a discriminative metric can be obtained. We demonstrate this by using AtmoDist to define a metric for GAN-based super resolution of vorticity and divergence. Our upscaled data matches both visually and in terms of its statistics a high resolution reference closely and it significantly outperform the state-of-the-art based on mean squared error. Since AtmoDist is unsupervised, only requires a temporal sequence of fields, and uses a simple auxiliary task, it has the potential to be of utility in a wide range of applications.

description: Carbonyl sulfide (OCS) is an abundant sulfur (S)-bearing species in the interstellar medium. It is present not only in the gas phase, but also on interstellar grains as a solid; therefore, OCS very likely undergoes physicochemical processes on icy surfaces at very low temperatures. The present study experimentally and computationally investigates the reaction of solid OCS with hydrogen (H) atoms on amorphous solid water at low temperatures. The results show that the addition of H to OCS proceeds via quantum tunneling, and further addition of H leads to the formation of carbon monoxide (CO), hydrogen sulfide (H2S), formaldehyde (H2CO), methanol (CH3OH) and thioformic acid (HC(O)SH). These experimental results are explained by our quantum chemical calculations, which demonstrate that the initial addition of H to the S atom of OCS is the most predominant, leading to the formation of OCS-H radicals. Once the formed OCS-H radical is stabilized on ice, further addition of H to the S atom yields CO and H2S, while that to the C atom yields HC(O)SH. We have also confirmed, in a separate experiment, the HC(O)SH formation by the HCO reactions with the SH radicals. The present results would have an important implication for the recent detection of HC(O)SH toward G+0.693-0.027.

description: It is generally accepted that many time series of practical interest exhibit strong dependence, i.e., long memory. For such series, the sample autocorrelations decay slowly and log-log periodogram plots indicate a straight-line relationship. This necessitates a class of models for describing such behavior. A popular class of such models is the autoregressive fractionally integrated moving average (ARFIMA) which is a linear process. However, there is also a need for nonlinear long memory models. For example, series of returns on financial assets typically tend to show zero correlation, whereas their squares or absolute values exhibit long memory. Furthermore, the search for a realistic mechanism for generating long memory has led to the development of other nonlinear long memory models. In this chapter, we will present several nonlinear long memory models, and discuss the properties of the models, as well as associated parametric andsemiparametric estimators.
title: Leyla and Mahmood - Emotions in Social Science Education

Publisher: name: sowi-online e.V., Bielefeld
Year: 2018

description: Purpose: The paper explores what emotions do in social science education through two specific cases and discusses the relation between emotion and politicization in the subject education.

Method/Approach: The cases are selected from an on-going dissertation project that uses interviews, video and observations in examining how social science education is played out in practice, with a focus on the students. Inspired by Sara Ahmed, emotion is seen as relational.

Findings: Seeing emotions as relational makes it possible to capture a dynamic in the classroom that brings a complexity to a discussion on social science education. There is a relation between emotion and politicization; in the two cases, emotion signals that a subject matter or situation is contested.

description: Recently an intriguing transient AT 2018lqh, with only a day-scale duration and a high luminosity of $7\times 10^{42}\ {\rm erg\ s^{-1}}$, has been discovered. While several possibilities are raised on its origin, the nature of this transient is yet to be unveiled. We propose that a black hole (BH) with $\sim 30\, M_\odot$ forming from a rotating blue supergiant can generate a transient like AT 2018lqh. We find that this scenario can consistently explain the optical/UV emission and the tentative late-time X-ray detection, as well as the radio upper limits. If super-Eddington accretion onto the nascent BH powers the X-ray emission, continued X-ray observations may be able to test the presence of an accretion disk around the BH.

We present a proof of this fact that is valid both for even and odd number of modes and relies solely on the antisymmetry of the scattering matrix imposed by time reversal symmetry.

title: Bio-inspired multisensory integration of social signals
Creators: name: Mansouri Benssassi, Esma
Publisher: name: University of St Andrews

description: Emotions understanding represents a core aspect of human communication. Our social behaviours are closely linked to expressing our emotions and understanding others’ emotional and mental states through social signals. Emotions are expressed in a multisensory manner, where humans use social signals from different sensory modalities such as facial expression, vocal changes, or body language. The human brain integrates all relevant information to create a new multisensory percept and derives emotional meaning. There exists a great interest for emotions recognition in various fields such as HCI, gaming, marketing, and assistive technologies. This demand is driving an increase in research on multisensory emotion recognition. The majority of existing work proceeds by extracting meaningful features from each modality and applying fusion techniques either at a feature level or decision level. However, these techniques are ineffective in translating the constant talk and feedback between different modalities. Such constant talk is particularly crucial in continuous emotion recognition, where one modality can predict, enhance and complete the other. This thesis proposes novel architectures for multisensory emotions recognition inspired by multisensory integration in the brain. First, we explore the use of bio-inspired unsupervised learning for unisensory emotion recognition for audio and visual modalities. Then we propose three multisensory integration models, based on different pathways for multisensory integration in the brain; that is, integration by convergence, early cross-modal enhancement, and integration through neural synchrony. The proposed models are designed and implemented using third generation neural networks, Spiking Neural Networks (SNN) with unsupervised learning. The models are evaluated using widely adopted, third-party datasets and compared to state-of-the-art multimodal fusion techniques, such as early, late and deep learning fusion. Evaluation results show that the three proposed models achieve comparable results to state-of-the-art supervised learning techniques. More importantly, this thesis shows models that can translate a constant talk between modalities during the training phase. Each modality can predict, complement and enhance the other using constant feedback. The cross-talk between modalities adds an insight into emotions compared to traditional fusion techniques.

description: Introductory calculus-based physics textbooks state that electromagnetic waves are transverse and list many of their properties, but most such textbooks do not bring forth arguments why this is so. Both physical and theoretical arguments are at a level appropriate for students of courses based on such books, and could be readily used by instructors of such courses. Here, we discuss two physical arguments (based on polarization experiments and on lack of monopole electromagnetic radiation), and the full argument for the transversality of (plane) electromagnetic waves based on the integral Maxwell equations. We also show, at a level appropriate for the introductory course, why the electric and magnetic fields in a wave are in phase and the relation of their magnitudes.

description: We will describe the thermal performance of power semiconductor module, which consists of hetero-junction bipolar transistors (HBTs), for mobile communication systems. We calculate the thermal resistance between the HBT fingers and the bottom surface of a multi-layer printed circuit board (PCB) using a finite element method (FEM). We applied a steady state analysis to evaluate the influence of design parameters on thermal resistance of the module. We found that the thickness of GaAs substrate, the thickness of multi-layer circuit board, the thermal conductivity of bonding material under GaAs substrate, and misalignment of thermal vias between each layer of PCB are the dominant parameter in thermal resistance of the module.

description: The pervasive use of information technologies (IT) has tremendously benefited our daily lives. However, unpredicted technical breakdowns and errors can lead to the experience of stress, which has been termed technostress. It remains poorly understood how people dynamically respond to unpredicted system runtime errors occurring while interacting with the IT systems on a behavioral and neuronal level. To elucidate the mechanisms underlying such processes, we conducted a functional magnetic resonance imaging (fMRI) study in which 15 young adults solved arithmetic problems of three difficulty levels (easy, medium and hard) while two types of system runtime errors (problem errors and feedback errors) occurred in an unexpected manner. The problem error condition consisted of apparently defective displays of the arithmetic problem and the feedback error condition involved erroneous feedback. We found that the problem errors positively influenced participants’ problem-solving performance at the high difficulty level (i.e., hard tasks) at the initial stage of the session, while feedback errors disturbed their performance. These dynamic behavioral changes are mainly associated with brain activation changes in the posterior cingulate and the default mode network, including the posterior cingulate cortex, the mPFC, the retrosplenial cortex and the parahippocampal gyrus. Our study illustrates the regulatory role of the posterior cingulate in coping with unpredicted errors as well as with dynamic changes in the environment.

De(con)structive poetics : readings of Hilda Doolittle’s The war trilogy
Creators: name: Scoggan, John William
Publisher: name: University of British Columbia
Year: 2010

description: The thesis studies linguistic, structural and post-structural models we may use for reading a classical text, in this case for reading Hilda Doolittle's The War Trilogy (Oxford University Press, 1944-1946). The object of the study is to demonstrate the application of recently developed critical techniques for examining a text that lies in the Anglo-American long poem tradition, contemporary with the writings of Ezra Pound, T. S. Eliot, Louis Zukofsky, and Charles Olson. The study is not restricted to a reading of The War Trilogy, as such, but also tries to define a poetics whose recursive formations typify what we call contemporary writing. The thesis explores theories for reading approaches that have been developed from Saussure's Course and from subsequent linguistic strategies outlined in the new critical modalities being advanced by Jacques Derrida, Paul Ricoeur, Michel Foucault, Roland Barthes, Jacques Lacan, Gilles Deleuze, Julia Kristeva, Jonathan Culler and others. The study is divided into two parts. Part One discusses critical methods, models and metaphors for outlining what is meant by de(con)structive reading and writing. Part Two gives interpretations of The War Trilogy based on the way these exegetical techniques focus on questions of textuality. Reading methods explored include: hermeneutic cryptanalysis, linguistic coding, linguistic modelling based on semiotics, communications theory in literary narratives, metaphors of writing and tracing, theory of supplementarity and difference, grammatology, schizanalysis, with provisional definitions for characterizing differences between classical polysemy and the writing of the modern genotext. Thus the study broadly differentiates between the composition of the classical Book, formed as a logocentric representation of concepts, and the decomposition or disintegration of concepts traced by the writing of the modern text, produced as a logodaedalic inscription. The general terms "classical" and "modern" are not strictly categorical distinctions but are used throughout as diacritical indicators for showing how and where Hilda Doolittle's The War Trilogy occupies an ambiguous marginality, leaving its mark along a "margin of difference" which is drawn between Book and text, Word and writing, reflecting both classical and modern styles of lecture and ecriture. The study also presents ways that "interpretation", as such, may be iconographically depicted by various mimetic tropes which religiously permeate and program the way we read, the deceptive circulation of the letter, the envelopment of concepts in writings, and their development in literary discourse.
Instability of the Body-Centered Cubic Lattice within the Sticky Hard Sphere and Lennard-Jones Model obtained from Exact Lattice Summations

description: A smooth path of rearrangement from the body-centered cubic (bcc) to the face-centered cubic (fcc) lattice is obtained by introducing a single parameter to cuboidal lattice vectors. As a result, we obtain analytical expressions in terms of lattice sums for the cohesive energy. This is described by a Lennard-Jones (LJ) interaction potential and the sticky hard sphere (SHS) model with an $r^{-n}$ long-range attractive term. These lattice sums are evaluated to computer precision by expansions in terms of a fast converging series of Bessel functions. Applying the whole range of lattice parameters for the SHS and LJ potentials demonstrates that the bcc phase is unstable (or at best metastable) toward distortion into the fcc phase. Even if more accurate potentials are used, such as the extended LJ potential for argon or chromium, the bcc phase remains unstable. This strongly indicates that the appearance of a low temperature bcc phase for several elements in the periodic table is due to higher than two-body forces in atomic interactions.

description: Only ~10% of baryons in the universe are in the form of stars, yet most models of luminous structure formation have concentrated on the properties of the luminous stellar matter. In this paper we focus on the "flip side" of galaxy formation and investigate the properties of the material that is not presently locked up in galaxies. This "by-product" of galaxy formation can be observed as an X-ray emitting plasma (the intracluster medium, hereafter ICM) in groups and clusters, and we present a version of the Durham semi-analytic galaxy formation model GALFORM that allows us to investigate the properties of the ICM. As we would expect on the basis of gravitational scaling arguments, the previous model (presented in Bower et al. 2006) fails to reproduce even the most basic observed properties of the ICM; however, we present a simple modification to the model to allow for heat input into the ICM from the AGN "radio mode" feedback. This heating acts to expel gas from the X-ray luminous central regions of the host halo. With this modification, the model reproduces the observed gas mass fractions and luminosity-temperature relation of groups and clusters. Introducing the heating process into the model requires changes to a number of model parameters in order to retain a good match to the observed galaxy properties. With the revised parameters, the best fitting luminosity function is comparable to that presented in Bower et al. (2006). The new model makes a fundamental step forward, providing a unified model of galaxy and cluster ICM formation. However, the detailed comparison with the data is not completely satisfactory, and we highlight key areas for improvement.

We demonstrate that limitations on the cycling efficiency due to the vibrational structure of the molecule can be mitigated by the use of repumping lasers. Images of the molecules obtained using the method are also shown. This technique gives rise to a new kind of ionizing radiation detector. The use of He$_2$ triplet molecules as tracer particles in the superfluid promises to be a powerful tool for visualization of both quantum and classical turbulence in liquid helium.

description: We obtain the equation governing the evolution of the cosmological gravitational-wave background, accounting for the presence of cosmic neutrinos, up to second order in perturbation theory. In particular, we focus on the epoch during radiation dominance, after neutrino decoupling, when neutrinos yield a relevant contribution to the total energy density and behave as collisionless ultra-relativistic particles. Besides recovering the standard damping effect due to neutrinos, a new source term for gravitational waves is shown to arise from the neutrino anisotropic stress tensor. The importance of such a source term, so far completely disregarded in the literature, is related to the high velocity dispersion of neutrinos in the considered epoch; its computation requires solving the full second-order Boltzmann equation for collisionless neutrinos.

title: To What Extent do Civic Education Curricula and Textbooks Establish Foundations for Developing Active Citizens in the Republic of Macedonia?
Creators: name: Mickovska-Raleva, Ana
Publisher: name: JSSE - Journal of Social Science Education
Year: 2019

description: Purpose: The paper presents a review of the process of inclusion of ‘civic education’ as part of the formal education system in the Republic of Macedonia, from its beginnings as project activity in the late 1990’s to its current implementation as a mandatory subject in the primary grades. Comparison is made between what was initially planned and what has been achieved in the area of civic education during this 20-year period, with a critical review on the potential of the subject for developing civic competencies. Method: The findings are based on content-analysis of curriculum goals and textbook tasks, through their classification in an indicators’ matrix of ‘Civic Key Competencies’ (as defined by the EC’s key competence framework for lifelong learning). Findings: The analysis provides insight into the frequency of curriculum goals and textbook tasks which relate to manifesting ‘civic competencies, from ‘knowledge’, ‘skills’, ‘attitudes’ and ‘values’, to the ‘behavior’ indicators, which should ideally be the goal of civic education.

description: We consider a two-player game of war of attrition under complete information. It is well-known that this class of games admits equilibria in pure, as well as mixed strategies, and much of the literature has focused on the latter. We show that if the players' payoffs whilst in "war" vary stochastically and their exit payoffs are heterogeneous, then the game admits Markov Perfect equilibria in pure strategies only. This is true irrespective of the degree of randomness and heterogeneity, thus highlighting the fragility of mixed-strategy equilibria to a natural perturbation of the canonical model. In contrast, when the players' flow payoffs are deterministic or their exit payoffs are homogeneous, the game admits equilibria in pure and mixed strategies.

Vortex pump for dilute Bose-Einstein condensates

description: The formation of vortices by topological phase engineering has been realized experimentally to create the first two- and four-quantum vortices in dilute atomic Bose-Einstein condensates [A. E. Leanhardt et al., Phys. Rev. Lett. 89, 190403 (2002)]. We consider a similar system, but in addition to the Ioffe-Pritchard magnetic trap we employ an additional hexapole field. By controlling cyclicly the strengths of these magnetic fields, we show that a fixed amount of vorticity can be added to the condensate in each cycle. In an adiabatic operation of this vortex pump, the appearance of vortices into the condensate is interpreted as the accumulation of a local Berry phase. Our design can be used as an experimentally realizable vortex source for possible vortex-based applications of dilute Bose-Einstein condensates.

description: Στόχος της παρούσας εργασίας είναι ο σχεδιασμός μιας ελάχιστης κατοικίας με έμφαση στη σχέση ανθρώπου-φύσης. Δεδομένης της σημερινής υποβαθμισμένης σχέσης του ανθρώπου με τη φύση, τα ερωτήματα που παράγονται αφορούν τον επαναπροσδιορισμό της σχέσης τους μέσω της έννοιας της μικροκατοικίας, δηλαδή σε μια μεθερμηνεία της αρχαίας καλύβας. Ο σύγχρονος αστικός τρόπος ζωής, ο οποίος χαρακτηρίζεται από ταχύτητα και κινητικότητα, έχει μεταβάλλει σημαντικά την σχέση του σύγχρονου ανθρώπου με τον χώρο και τον τρόπο που βιώνει την κατοικία. Με απασχόλησε η μεταβολή της σχέσης του ανθρώπου με τον χώρο που κατοικεί και πως αυτή η μεταβολή έχει επαναπροσδιορίσει την χωρική εμπειρία. Στις σύγχρονες κατοικίες των μεγάλων αστικών κέντρων, ο ζωτικός χώρος μειώνεται συνεχώς. Αυτό σε συνδυασμό με την υπερκατανάλωση του σύγχρονου ανθρώπου οδηγεί σε μικρής έκτασης υπερφορτωμένους χώρους, σε μία προσπάθεια να στοιβαχτούν τα πάντα σε ελάχιστα τετραγωνικά. Επιπλέον, η αστικοποίηση που είναι πια παγκόσμιο φαινόμενο, και εξαπλώνεται με ταχύτατους ρυθμούς, αποξενώνει τους ανθρώπους από την εμπειρία της φύσης. Ο σύγχρονος άνθρωπος έχει αποξενωθεί σε μεγάλο βαθμό από το φυσικό περιβάλλον και η προσπάθεια του να ανακτήσει τη σχέση του με την φύση περιορίζεται κυρίως σε τεχνητές εμπειρίες. Πρόκειται να παρουσιαστεί ο σχεδιασμός μιας κατοικίας ελάχιστης δόμησης, με όσο το δυνατόν μικρότερο ίχνος στο φυσικό περιβάλλον, η οποία να εξυπηρετεί τη συνολική εμπειρία του κατοικείν εναρμονισμένη με την φύση.

description: We classify, in a group theoretical manner, the BPS configurations in the multiple M2-brane theory recently proposed by Bagger and Lambert. We present three types of BPS equations preserving various fractions of supersymmetries: in the first type we have constant fields and the interactions are purely algebraic in nature; in the second type the equations are invariant under spatial rotation SO(2), and the fields can be time-dependent; in the third class the equations are invariant under boost SO(1,1) and provide the eleven-dimensional generalizations of the Nahm equations. The BPS equations for different number of supersymmetries exhibit the division algebra structures: octonion, quarternion or complex.

Έγινε ανασκόπηση της ποικιλίας σε όλους τομείς της αναλύοντάς την σε επίπεδο αμπελογραφικό, αγρολογικό, οργανοληπτικό αλλά και ως προς την γεωγραφική της προέλευση και ιστορία. Eπίσης, έγινε προσπάθεια να απαντηθούν δύο βασικά ερωτήματα: ποια η επίδραση του Sauvignon blanc στην οικονομία του οίνου και ποιες οι βέλτιστες συνθήκες για την παραγωγή ενός κρασιού υψηλής ποιότητας. Όλες αυτές οι συνθήκες πρέπει να εξισορροπούνται μεταξύ της παραδοσιακής αμπελουργίας και της τάσης του Νέου Κόσμου. Η μελέτη απέδειξε ότι η ανάλυση swot μπορεί να αποδειχθεί ως αποτελεσματικό εργαλείο σε συνδυασμό με τη χρήση παραδοσιακών τεχνικών αμπελουργίας, το terroir και τη χρήση σύγχρονων τεχνικών οργανοληπτικής αξιολόγησης προκειμένου να επιτευχθεί η υψηλή ποιότητα του προϊόντος με τις απαιτήσεις των καταναλωτών.

description: Presentation of the extended abstract at the TODO International Conference on Open Data in Zagreb, Croatia on 29 November 2022. Open data has various potential benefits, including stimulating innovation, enhancing accountability and transparency, and improving the reproducibility and dissemination of academic research. However, current open data initiatives have various shortcomings, including the mismatch between the supply and demand of open data and the lack of its reuse. To address these weaknesses, the role of open data intermediaries in facilitating the use of and access to open data is considered instrumental. Nevertheless, some literature noted the lack of development of their business models, which may compromise their long-term survival. Before their business models can be further developed, a clear view of the existing business models is needed. Hence, the objective of this extended abstract is to review current business models of open data intermediaries in academic literature.
