description: Ο σκοπός της παρούσας έρευνας είναι να επιχειρήσει να διερευνήσει τις προτιμήσεις, διαθέσεις και απόψεις των καταναλωτών που διαμένουν στο Νομό Πέλλας σχετικά με το βιολογικό κρασί. Αρχικά πραγματοποιήθηκε η ποιοτική έρευνα, κατά το χρονικό διάστημα 1-28 Μαϊου του 2008. Ο αριθμός των ομάδων εστίασης (focus group) ήταν τρεις. Κάθε ομάδα αποτελούνταν από έξι άτομα. Τα δεκαοχτώ άτομα υποβλήθηκαν σε ερωτήσεις «ανοιχτού» τύπου με απώτερο στόχο τη σύνταξη του ερωτηματολογίου της ποσοτικής έρευνας. Για το σκοπό βέβαια αυτό αξιοποιήθηκε και η μελέτη της ειδικής βιβλιογραφίας. Το ερωτηματολόγιο της ποσοτικής έρευνας εφαρμόστηκε σε δείγμα 100 καταναλωτών από τις 1 Ιουνίου έως τις 10 Ιουλίου του 2008.Χρησιμοποιήθηκαν ως επί το πλείστον ερωτήσεις «κλειστού» τύπου και η εξαγωγή των συμπερασμάτων έγινε με τη χρήση του στατιστικού πακέτου SPSS και τη μέθοδο του Χ2. Από τα αποτελέσματα προκύπτει ότι οι καταναλωτές δεν είναι εξοικειωμένοι με το βιολογικό κρασί. Ενώ καταναλώνουν κρασί σε ποσοστό 82%, μόλις το 30% καταναλώνει βιολογικό κρασί και αυτό περιστασιακά. Παρουσιάζουν θετική γνώμη ως προς το προϊόν αυτό και δικαιολογούν την τιμή του εξαιτίας της ιδιάζουσας παραγωγής. Εμφανίζουν όμως δυσπιστία ως προς το σύστημα πιστοποίησης.
description: The main goal of this research is to investigate the preferences, the dispositions and the views of consumers who live in the prefecture of Pella about organic wine. Firstly, a qualitative research was done during 1-28 May. The number of focus groups were three. Every team consisted of six members. The eighteen members were subjected to “open type”questions with the goal of drawing of the questionnaire of quantitative research. The questionnaire of quantitative research was applied to a sample of one hundrend consumers during 1 st June until 10th July 2008. For this purpose , “closed type” questions were used and the extraction of the results was done with the use of statistical package SPSS and X2. It is derived , that the consumers are not familiar with organic wine. While they consume wine in a percentage of 82%, only 30% of them consume organic wine and this only occasionally. They also present a positive opinion to this product and they justify its price due to the particular way of production. Hence, they present suspicion to the certification bodies.

description: This thesis is about Analysis of Time Series and forecasting. At the first chapter there is an introduction to time series and the forecasting techniques. At the second chapter we examine smoothing techniques such as the simple moving average, the simple exponential smoothing, the double moving average, the Brown method, the Holt method and the Winters method. At the third chapter we examine the time series decomposition method which deals with the deconstruction of the trend component, the seasonality component, the cyclical component and the irregular component. At the fourth chapter we apply these methods to time series and perform forecasts in order to contrast the methods. At the fifth chapter we examine the ARIMA models and at the sixth chapter we apply the arima models to time series so as to perform forecasts.

Publisher: name: University of Tasmania

description: Social-cognitive difficulties in Multiple Sclerosis (MS) have devastating psychosocial impacts, yet assessment is challenging and treatments scarce. This pilot longitudinal study examined the potential role of inflammatory cytokines and nicotinamide adenine dinucleotide (NAD+) as predictive biomarkers of social-cognitive abilities in people with MS (pwMS). Seventeen pwMS (13 female, 18-62 years old) provided blood samples and were assessed for the social-cognitive domains of emotion recognition and sarcasm detection tapping into Theory of Mind, using The Awareness of Social Inference Test-Short (TASIT-S) at baseline and after 5-to-6 years. As hypothesised, higher levels of anti-inflammatory cytokine IL-4 related to better sarcasm detection. However, relationships between pro-inflammatory cytokines and TASIT-S scores were unexpected, with lower levels of cytokines relating to better emotion recognition, but higher levels relating to better sarcasm detection at baseline and follow-up. TASIT-S scores and cytokine levels did not change over time. Select cytokines and NAD+ may be predictive of long-term social-cognitive performance. These pilot results suggest a larger, fully powered study to further examine these relationships is needed. The identification of predictive biomarkers could both facilitate timely assessment and intervention for social-cognitive difficulties, and the development of potential pharmacotherapeutic targets, which would improve health-related quality of life in pwMS.

description: The goal of this paper is to propose an approach to the formulation of dynamics for causal sets and coupled matter fields. We start from the continuum version of the action for a Klein-Gordon field coupled to gravity, and rewrite it first using quantities that have a direct correspondent in the case of a causal set, namely volumes, causal relations, and timelike lengths, as variables to describe the geometry. In this step, the local Lagrangian density $L(f;x)$ for a set of fields $f$ is recast into a quasilocal expression $L_0(f;p,q)$ that depends on pairs of causally related points $p \prec q$ and is a function of the values of $f$ in the Alexandrov set defined by those points, and whose limit as $p$ and $q$ approach a common point $x$ is $L(f;x)$. We then describe how to discretize $L_0(f;p,q)$, and use it to define a discrete action.

description: The comprehensive depiction of the many-body effects governing nanoconfined electrolytes is an essential step for the conception of nanofluidic devices with optimized performance. By incorporating self-consistently multivalent charges into the Poisson-Boltzmann equation dressed by a background monovalent salt, we investigate the impact of strong-coupling electrostatics on the nanofluidic transport of electrolyte mixtures. We find that the experimentally observed negative streaming currents in anionic nanochannels originate from the collective effect of the Cl attraction by the interfacially adsorbed multivalent cations, and the no-slip layer reducing the hydrodynamic contribution of these cations to the net current. The like-charge current condition emerging from this collective mechanism is shown to be the reversal of the average potential within the no-slip zone. Applying the formalism to surface-coated membrane nanoslits located in the giant dielectric permittivity regime, we reveal a new type of streaming current activated by attractive polarization forces. Under the effect of these forces, the addition of multivalent ions into the KCl solution sets a charge separation and generates a counterion current between the neutral slit walls. The adjustability of the current characteristics solely via the valency and amount of the added multivalent ions identifies the underlying process as a promising mechanism for nanofluidic ion separation purposes.

description: Deep learning models have demonstrated superior performance in several application problems, such as image classification and speech processing. However, creating a deep learning model using health record data requires addressing certain privacy challenges that bring unique concerns to researchers working in this domain. One effective way to handle such private data issues is to generate realistic synthetic data that can provide practically acceptable data quality and correspondingly the model performance. To tackle this challenge, we develop a differentially private framework for synthetic data generation using Rényi differential privacy. Our approach builds on convolutional autoencoders and convolutional generative adversarial networks to preserve some of the critical characteristics of the generated synthetic data. In addition, our model can also capture the temporal information and feature correlations that might be present in the original data. We demonstrate that our model outperforms existing state-of-the-art models under the same privacy budget using several publicly available benchmark medical datasets in both supervised and unsupervised settings.

description: The plethora of photometric data collected by the Kepler space telescope has promoted the detection of tens of thousands of stellar rotation periods. However, these periods are not found to an equal extent among different spectral types. Interestingly, early G-type stars with near-solar rotation periods are strongly underrepresented among those stars with known rotation periods. In this study we investigate whether the small number of such stars can be explained by difficulties in the period determination from photometric time series. For that purpose, we generate model light curves of early G-type stars with solar rotation periods for different inclination angles, metallicities and (magnitude-dependent) noise levels. We find that the detectability is determined by the predominant type of activity (i.e. spot or faculae domination) on the surface, which defines the degree of irregularity of the light curve, and further depends on the level of photometric noise. These two effects significantly complicate the period detection and explain the lack of solar-like stars with known near-solar rotation periods. We conclude that the rotation periods of the majority of solar-like stars with near-solar rotation periods remain undetected to date. Finally, we promote the use of new techniques to recover more periods of near-solar rotators.

description: Lots of researchers have been troubled by the difficulties that pupils cope with in learning Geometry and tried to explain why this happens and what teachers can do in teaching to make Geometry more understandable to pupils. In the 50s, Dutch teachers Pierre van Hiele and his wife, Dina van Hiele-Geldof, (1957) suggested a theoretical model of understanding Geometry, which included five levels of developing geometrical thought and five learning phases. An important parameter of the model had been the development of insight in pupils, so that they move from one level to a higher one. Van Hiele’s theory had been known in many countries like the Soviet Union, the United States and Greece as well.The aim of this research is to find out the level of geometrical thought in pupils of primary school and how geometrical activities, concerning the geometrical shapes and their properties in the new school books of Mathematics in primary school, are adapted to the level of geometrical thought of pupils in each class, depended on the van Hiele theory.

Safety verification conditions for software-intensive critical systems
Creators: name: Wong, Ken
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation proposes an approach to generating "safety verification conditions" (SVCs) that improves upon the accuracy and thoroughness of approaches that rely primarily on engineering judgment. This approach, "Verification Tree Method" (VTM), is part of an overall system safety engineering process intended to eliminate or mitigate hazards in the development of a software-intensive critical system. VTM carried out to the level of a "black box" view of the system results in a set of system safety requirements. VTM can also be used to derive SVCs at the software component and the source code levels. The SVCs can then be used as input into the corresponding level of testing. VTM is based on Fault Tree Analysis (FTA). Like FTA, VTM involves tracing a given hazard is traced backwards through the system to cover all the ways in which a hazard can occur. VTM enhances FTA with a constrained syntax and "proof-by-contradiction" style reasoning to support the systematic derivation of SVCs. The SVCs include key safety-related temporal relationships. The result of the analysis is a rigorous safety argument that provides greater confidence that the SVCs, if satisfied, will be sufficient to mitigate the hazard. This informal argument can be validated with a formal verification technique. VTM is illustrated in this dissertation with a (hypothetical) chemical factory information system.

description: A democratic society needs citizens informed, that have the possibility of organising, processing and interpreting the information they accept and according these they decide to profit of society. So the role of mathematical literacy in the frame of formal education acquires particular importance. From what first and more basic significances of statistics, with which the small children come in contact, in the years of first degree education, it is the significance of mean. A metre of central tendency of distribution, that while it shows simple, nevertheless is complex and conceptually exigent process.With the present study, it is sought to investigate the ways with which the children of Primary School comprehend the significance of mean as well as the misconceptions that they develop at the process of growth of significance.

description: A range of experimental results point to the existence of a massive neutrino. The recent high precision measurements of the cosmic microwave background and the large scale surveys of galaxies can be used to place an upper bound on this mass. In this paper we perform a thorough analysis of all assumptions that go into obtaining a credible limit on $\sum m_ν$. In particular we explore the impact of extending parameter space beyond the current standard cosmological model, the importance of priors and the uncertainties due to biasing in large scale structure. We find that the mass constraints are independent of the choice of parameterization as well as the inclusion of spatial curvature. The results of including the possibility of dark energy and tensors perturbations are shown to depend critically on the data sets used. The difference between an upper bound of 2.2 eV, assuming generic initial conditions, and an upper bound of 0.63 eV, assuming adiabaticity and a galaxy bias of 1, demonstrate the dependence of such a constraint on the assumptions in the analysis.

description: Characteristic of the law of the commercial paper is the limitation of the objections, which the debtor can raise against their bearer. Those objections depend on the way, in which the payee has been defined. So, in a registered commercial paper every objection can be raised. In a check to bearer the debtor can raise only the objections, which the article 892 of civil code provides. When the commercial paper is drawd “to order”, the debtor can raise only the objections, which are related with the absence of the debtor’s will, the objections, which can be concluded from the commercial paper itself, the personal objections and at last the objections, which can be raised against the debtor of bad faith.

description: The 'Quartet' is an informal diplomatic mechanism designed to coordinate the efforts of major actors within the context of the Israeli-Palestinian conflict. Formed in 2001, the grouping is composed of representatives from the United States, the European Union, Russia and the Office of the UN Secretary General. Existing analysis of the Quartet, especially concerning the capacity of the grouping to facilitate both individual and collective outcomes for its members, is in some respects misleading. This thesis establishes the historical precedents to the formation of the Quartet, and examines the outputs and outcomes of the grouping within the politico-strategic context of the Middle East peace process from 2001-2011. It presents each of the Quartet members as actors, who, while working in support of a peace process between the Israelis and Palestinians, also hoped to advance their national or organisational objectives through the association itself. By examining the interplay between the complimentary and competing agendas and capabilities of the Quartet members, the thesis aims to provide enhanced insight into the role of external parties in the Israeli-Palestinian peace process. Accordingly, it examines the key factors that motivated individual governments and institutions to form the Quartet, and analyses the extent to which the Quartet members had both collective and individual objectives for the grouping. In examining whether these objectives were achieved during the period, the thesis argues that the outcomes of the Quartet were shaped by its internal decision-making processes, the exclusivity of the US-Israel relationship, the nature of the Israeli-Palestinian conflict and the regional contexts in which its members sought collective influence. It argues that the Quartet demonstrated potential as a diplomatic tool, although in practice it had greater utility as a forum for coordination among its members than for influencing the behaviour of the parties to the conflict.

description: We present the mass functions of actively accreting supermassive black holes over the redshift range 0.3 <= z <= 5 for a well-defined, homogeneous sample of 15,180 quasars from the Sloan Digital Sky Survey Data Release 3 (SDSS DR3) within an effective area of 1644 square degrees. This sample is the most uniform statistically significant subset available for the DR3 quasar sample. It was used for the DR3 quasar luminosity function, presented by Richards et al., and is the only sample suitable for the determination of the SDSS quasar black hole mass function. The sample extends from i = 15 to i = 19.1 at z less than about 3 and to i = 20.2 for z greater than about 3. The mass functions display a rise and fall in the space density distribution of active black holes at all epochs. Within the uncertainties the high-mass decline is consistent with a constant slope of beta of about -3.3 at all epochs. This slope is similar to the bright end slope of the luminosity function for epochs below z = 4. Our tests suggest that the down-turn toward lower mass values is due to incompleteness of the quasar sample with respect to black hole mass. Further details and analysis of these mass functions will be presented in forthcoming papers.

description: We examine the analogue one-dimensional quantum mechanics problem associated with bulk scalars and fermions in a slice of AdS_5. The ``Schroedinger'' potential can take on different qualitative shapes depending on the values of the mass parameters in the bulk theory. Several interesting correlations between the shape of the Schroedinger potential and the holographic theory exist. We show that the quantum mechanical picture is a useful guide to the holographic theory by examining applications from phenomenology.

Pairing by a dynamical interaction in a metal

description: We consider pairing of itinerant fermions in a metal near a quantum-critical point (QCP) towards some form of particle-hole order (nematic, spin-density-wave, charge-density-wave, etc). At a QCP, the dominant interaction between fermions comes from exchanging massless fluctuations of a critical order parameter. At low energies, this physics can be described by an effective model with the dynamical electron-electron interaction $V(Ω_m) \propto 1/|Ω_m|^γ$, up to some upper cutoff $Λ$. The case $γ=0$ corresponds to BCS theory, and can be solved by summing up geometric series of Cooper logarithms. We show that for a finite $γ$, the pairing problem is still marginal (i.e., perturbation series are logarithmic), but one needs to go beyond logarithmic approximation to find the pairing instability. We discuss specifics of the pairing at $γ>0$ in some detail and also analyze the marginal case $γ= 0+$, when $V(Ω_m) = λ\log{(Λ/|Ω_m|)}$. We show that in this case the summation of Cooper logarithms does yield the pairing instability at $λ\log^2{(Λ/T_c)} = O(1)$, but the logarithmic series are not geometrical. We reformulate the pairing problem in terms of a renormalization group (RG) flow of the coupling, and show that the RG equation is different in the cases $γ=0$, $γ= 0+$, and $γ>0$.

Proper Motions of PSRs B1757-24 and B1951+32: Implications for Ages and Associations

description: Over the last decade, considerable effort has been made to measure the proper motions of the pulsars B1757-24 and B1951+32 in order to establish or refute associations with nearby supernova remnants and to understand better the complicated geometries of their surrounding nebulae. We present proper motion measurements of both pulsars with the Very Large Array, increasing the time baselines of the measurements from 3.9 yr to 6.5 yr and from 12.0 yr to 14.5 yr, respectively, compared to previous observations. We confirm the non-detection of proper motion of PSR B1757-24, and our measurement of (mu_a, mu_d) = (-11 +/- 9, -1 +/- 15) mas yr^{-1} confirms that the association of PSR B1757-24 with SNR G5.4-1.2 is unlikely for the pulsar characteristic age of 15.5 kyr, although an association can not be excluded for a significantly larger age. For PSR B1951+32, we measure a proper motion of (mu_a, mu_d) = (-28.8 +/- 0.9, -14.7 +/- 0.9) mas yr^{-1}, reducing the uncertainty in the proper motion by a factor of two compared to previous results. After correcting to the local standard of rest, the proper motion indicates a kinetic age of ~51 kyr for the pulsar, assuming it was born near the geometric center of the supernova remnant. The radio-bright arc of emission along the pulsar proper motion vector shows time-variable structure, but moves with the pulsar at an approximately constant separation ~2.5", lending weight to its interpretation as a shock structure driven by the pulsar.

Wavelet radiosity in computer graphics
Creators: name: Ziegler, Philipp
Publisher: name: University of British Columbia
Year: 2009

description: The thesis presents an overview of the recent development of radiosity methods in computer graphics in a uniform mathematical framework. The focus is on hierarchical methods using wavelets. The thesis experimentally analyzes the behavior of higher-order wavelet bases in hierarchical methods. The functions applied are multiwavelets and a family of wavelets proposed by Cohen, Daubechies and Vial. The latter wavelets have overlapping support. Generally, we find that higher-order wavelet bases save memory compared to Haar wavelets, while they require more time for the computation. Furthermore, we investigate how Krylov subspace methods can be employed to solve the discrete system of equations arising in hierarchical methods. We show that the Generalized Minimal Residual method (GMRES) is advantageous compared to the usually employed Picard iteration.

Ερχόμενοι όμως όλοι αυτοί σε επαφή με τα υποκείμενα της έρευνας μας, αποδεικνύεται ότι οι γυναίκες αυτές δεν ήταν παθητικά υποκείμενα της πατριαρχικής κοινωνίας μέσα στην οποία ζούσαν, αλλά ενεργοί δράστες που έπαιρναν πρωτοβουλίες & λάμβαναν σημαντικές αποφάσεις στα πλαίσια ενός καλά δομημένου παρασκηνίου.
description: The aim of this dissertation is the study of the position of women based on three cases: the Muslim women of the imperial harem of the Ottoman Empire, the bourgeoisie of Constantinople and the Greek women of Chios and Mytilene as these are described in the writings of the male and female excursionists of that era.For the female and male excursionists, these women were nothing else than women of the East. Both Greek and Muslim women symbolized the exotic, the foreign, creating emotions of fear and appeal at the same time and occasionally exalting their figure to the sphere of fantasy. Through our research it is proved that these women were not passive subjects in the patriarchal society which they lived in, but active members who took initiative and important decisions within the framework of a well-structured backstairs influence.
