description: Σκοπός της διπλωματικής ήταν η ανάλυση του Συστήματος Εγγύησης Καταθέσεων και Επενδύσεων. Εξετάσαμε το σκοπό του Συστήματος Εγγύησης Καταθέσεων και Επενδύσεων που δεν είναι άλλος από την διασφάλιση αφενός των καταθέσεων των καταθετών των πιστωτικών ιδρυμάτων που συμμετέχουν σε αυτό και αφετέρου η διασφάλιση των απαιτήσεων των επενδυτών-πελατών των πιστωτικών ιδρυμάτων που ,επίσης, συμμετέχουν σε αυτό. Στην συνέχεια εξετάσαμε τον θεσμό του Ταμείου Εγγύησης Καταθέσεων και Επενδύσεων. Ειδικότερα αναλύσαμε την διοίκηση του και τον τρόπο της συμμετοχής των πιστωτικών ιδρυμάτων σε αυτό. Επιπλέον , στην παρούσα διπλωματική έγινε εκτενής αναφορά στην δυνατότητα παροχής αποζημιώσεων σε καταθέτες και επενδυτές-πελάτες εκ μέρους του Ταμείου. Τέλος , έγινε αναφορά και στην αναγκαιότητα ύπαρξης του Ταμείου λόγω της παρούσας κρίσης στον τραπεζικό τομέα.
description: The purpose of this dissertation was the analysis of Deposit Guarantee Schemes. We looked into the Deposit Guarantee Schemes’ purpose, which is no other than the ensurance of credit institutions depositors’ deposits participating in it on the one hand, and the ensurance of credit institutions investors’-customers’ demands participating in it, on the other. Afterwards, we looked into the institution of the Deposit Guarantee Fund and Investment. Specifically, we analysed the administration and the way credit institutions could participate in it. Additionally, in this very dissertation extensive reference was made as for the potential of providing compensation to depositors and investors/customers on behalf of the Fund. Finally, a reference was made to the necessity of Fund existence, due to the current crisis in the banking sector.

description: Superdiffusive finite-temperature transport has been recently observed in a variety of integrable systems with nonabelian global symmetries. Superdiffusion is caused by giant Goldstone-like quasiparticles stabilized by integrability. Here, we argue that these giant quasiparticles remain long-lived, and give divergent contributions to the low-frequency conductivity $σ(ω)$, even in systems that are not perfectly integrable. We find, perturbatively, that $ σ(ω) \sim ω^{-1/3}$ for translation-invariant static perturbations that conserve energy, and $σ(ω) \sim | \log ω|$ for noisy perturbations. The (presumable) crossover to regular diffusion appears to lie beyond low-order perturbation theory. By contrast, integrability-breaking perturbations that break the nonabelian symmetry yield conventional diffusion. Numerical evidence supports the distinction between these two classes of perturbations.

Studies of a sperm antigen recognized by two monoclonal antibodies
Creators: name: McChesney, Patricia
Publisher: name: University of British Columbia
Year: 2009

description: The monoclonal antibodies HSA-5 and HSA-6 were generated by others in Dr. Lee’s lab against ionophore-treated acrosome reacted human sperm in 1989. They were submitted to the second WHO workshop for interlaboratory evaluations of their potential to be immunocontraceptive vaccine candidates, and were concluded to be Thigh priority candidates in 1989. The two antibodies recognize identical bands on a western blot of crude human sperm extract, which indicate that they recognize the same protein (HSAg-5/6). Indirect immunofluorescent assays performed in our lab have shown that the HSAg-5/6 is locted in the equatorial region of methanol-fixed human sperm, as well as on the head and tail of mouse sperm. The antigen was immunolocalized on human sperm by Homyk et al (1993) who showed that HSAg-5/6 was located on both the inner and outer acrosomal membranes. The corresponding antigen from mouse sperm which binds to HSA-5 and HSA-6 was found to have characteristics identical to those of the human protein as analyzed by western blot assay. The purpose of my project was to study the molecular nature of human HSAg-5/6, and isolate cDNA clones of the corresponding antigen from mouse. This characterization included studying the purified human antigen, and molecular cloning of the homologous protein from a mouse testis cDNA library. From work performed by Dr. T. Yoshiki, it was established that purified HSAg-5!6 is a protein with a molecular mass of approximately 6OkD. My studies established that the isolated cDNA clone expresses the C-terminal region of the protein and accounts for approximately 13% of the total molecular weight, based upon the approximated molecular weight of the cloned fusion protein compared to the molecular weight of the native HSAg 5/6. However, antigenic sites for both monoclonal antibodies lie in this tail end, which suggests that the C-terminus of HSAg-5/6 is exposed to the environment such that an immune response occurs. The studies of HSAg-516 described in this thesis not only supplement our current knowledge regarding sperm-specific proteins, but also aid in development of an immunocontraceptive vaccine.

description: In the operation & maintenance (O&M) of photovoltaic (PV) plants, the early identification of failures has become crucial to maintain productivity and prolong components' life. Of all defects, cell-level anomalies can lead to serious failures and may affect surrounding PV modules in the long run. These fine defects are usually captured with high spatial resolution electroluminescence (EL) imaging. The difficulty of acquiring such images has limited the availability of data. For this work, multiple data resources and augmentation techniques have been used to surpass this limitation. Current state-of-the-art detection methods extract barely low-level information from individual PV cell images, and their performance is conditioned by the available training data. In this article, we propose an end-to-end deep learning pipeline that detects, locates and segments cell-level anomalies from entire photovoltaic modules via EL images. The proposed modular pipeline combines three deep learning techniques: 1. object detection (modified Faster-RNN), 2. image classification (EfficientNet) and 3. weakly supervised segmentation (autoencoder). The modular nature of the pipeline allows to upgrade the deep learning models to the further improvements in the state-of-the-art and also extend the pipeline towards new functionalities.

description: In this study, we investigate the spatially nonuniform-temperature effects on the QCD chiral phase transition in the heavy-ion collisions. Since the QCD effective theory and the Ising model belong to the same universality class, we start our discussion by mimicking the QCD effective potential with an Ising-like effective potential. In contrast to the dynamical slowing down effects which delays the phase transition from quark-gluon-plasma to hadron gas, the spatially nonuniform-temperature effects show a possibility to lift the phase transition temperature. Besides, both the fluctuations and the correlation length are enhanced in the phase transition region. Furthermore, the critical phenomena is strongly suppressed like as the critical slowing down effects. The underlying mechanism is the nonzero-momentum mode fluctuations of the order parameter induced by the nonuniform temperature. Our study provides a method to evaluate the nonuniform-temperature effects, and illustrate its potential influence on analyzing the QCD phase transition signals at RHIC.

description: We introduce a thermodynamically consistent, minimal stochastic model for complementary logic gates built with field-effect transistors. We characterize the performance of such gates with tools from information theory and study the interplay between accuracy, speed, and dissipation of computations. With a few universal building blocks, such as the NOT and NAND gates, we are able to model arbitrary combinatorial and sequential logic circuits, which are modularized to implement computing tasks. We find generically that high accuracy can be achieved provided sufficient energy consumption and time to perform the computation. However, for low-energy computing, accuracy and speed are coupled in a way that depends on the device architecture and task. Our work bridges the gap between the engineering of low dissipation digital devices and theoretical developments in stochastic thermodynamics, and provides a platform to study design principles for low dissipation digital devices.

description: The purpose of this paper is to study, record, and analyze learner errors regarding the placement of the verb in the German language in the light of computational linguistics. The paper begins with an exposition of the theoretical framework concerning the placement of the verb in the German language. The three possible placements (the verb in the first, second, and final position) are presented along with any deviations and/or exceptions from each rule respectively. The research focuses on the collection, analysis, and evaluation of data from errors in verb placement. More specifically, a textual body was created from essays written by B1 and B2 level learners and learner errors are annotated with the use of XML (eXtensible Markup Language). What follows is their categorization and analysis, while certain conclusions are drawn in the framework of this specific research. Finally, a discussion takes place with suggestions regarding the further utilization and optimization of XML and of computational linguistics for error analysis and corpora annotation.
$ψ(3770)$ and $B$ meson exclusive decay $B \to ψ(3770) K$ in QCD factorization

description: Belle has observed surprisingly copious production of $ψ(3770)$ in $B$ meson decay $B\to ψ(3770)K$, of which the rate is comparable to that of $B\to ψ(3686)K$. We study this puzzling process in the QCD factorization approach with the effect of S-D mixing considered. We find that the soft scattering effects in the spectator interactions play an essential role. With a proper parametrization for the higher twist soft end-point singularities associated with kaon, and with the S-D mixing angle $θ=-12^{\circ}$, the calculated decay rates can be close to the data. Implications of these soft spectator effects to other charmonium production in $B$ exclusive decays are also emphasized.

description: Moiré heterobilayer transition metal dichalcogenides (TMDs) emerge as an ideal system for simulating the single-band Hubbard model and interesting correlated phases have been observed in these systems. Nevertheless, the moiré bands in heterobilayer TMDs were believed to be topologically trivial. Recently, it was reported that both a quantum valley Hall insulating state at filling $ν=2$ (two holes per moiré unit cell) and a valley-polarized quantum anomalous Hall state at filling $ν=1$ were observed in AB stacked moiré MoTe$_2$/WSe$_2$ heterobilayers. However, how the topologically nontrivial states emerge is not known. In this work, we propose that the pseudo-magnetic fields induced by lattice relaxation in moiré MoTe$_2$/WSe$_2$ heterobilayers could naturally give rise to moiré bands with finite Chern numbers. We show that a time-reversal invariant quantum valley Hall insulator is formed at full-filing $ν=2$, when two moiré bands with opposite Chern numbers are filled. At half-filling $ν=1$, Coulomb interaction lifts the valley degeneracy and results in a valley-polarized quantum anomalous Hall state, as observed in the experiment. Our theory identifies a new way to achieve topologically non-trivial states in heterobilayer TMD materials.

description: We show that the Adaptive Greedy algorithm of Golovin and Krause (2011) achieves an approximation bound of $(\ln (Q/η)+1)$ for Stochastic Submodular Cover: here $Q$ is the "goal value" and $η$ is the smallest non-zero marginal increase in utility deliverable by an item. (For integer-valued utility functions, we show a bound of $H(Q)$, where $H(Q)$ is the $Q^{th}$ Harmonic number.) Although this bound was claimed by Golovin and Krause in the original version of their paper, the proof was later shown to be incorrect by Nan and Saligrama (2017). The subsequent corrected proof of Golovin and Krause (2017) gives a quadratic bound of $(\ln(Q/η) + 1)^2$. Other previous bounds for the problem are $56(\ln(Q/η) + 1)$, implied by work of Im et al. (2016) on a related problem, and $k(\ln (Q/η)+1)$, due to Deshpande et al. (2016) and Hellerstein and Kletenik (2018), where $k$ is the number of states. Our bound generalizes the well-known $(\ln~m + 1)$ approximation bound on the greedy algorithm for the classical Set Cover problem, where $m$ is the size of the ground set.

description: The thermal evaluation of a Shell and Tube Heat Exchanger (STHE) is essential for maximizing heat transfer efficiency and promoting energy conservation in diverse industrial applications. This paper provides a performance assessment and temperature distributions of Shell and Tube Heat Exchanger (STHE) with parallel flow arrangement and strategies to improve heat transfer efficiency. This paper experimentally examined the performance and Temperature distribution of a shell and tube heat exchanger: heat transfer rates, heat exchanger efficiency, and temperature profiles, are assessed using experimental datasets. The findings revealed that the shell and tube heat exchanger have an efficiency of approximately 94.2%. The inlet temperature of hot temperature is reduced by 31.1oC while the inlet temperature of cold increases by 14,1oC as time increases. The outlet temperature of hot temperature is reduced by 25.2oC while the outlet temperature of cold increases by 21.5oC as time increases. Additionally, the temperature difference decreases which enhances the efficacy of the system and the potential for thermal equilibrium by incorporating an increased heat recovery. The results emphasize the need for appropriate thermal design and maintenance to enhance the efficiency of heat exchangers, conserve energy, and extend the lifespan of equipment in industrial operations.

description: Mit der gestiegenen Bedeutung der Biogasproduktion in Deutschland begann eine Diskussion um und Forschung über Gärsubstratalternativen zum Mais. Im Zusammenhang mit der zunehmenden regionalen Konzentration der Viehhaltung wird über den Einsatz von Feststoffen aus der Gülleseparation in Biogasanlagen diskutiert. Basierend auf einer Online-Umfrage unter 110 Betreibern von Biogasanlagen arbeitet die vorliegende Studie die Bedeutung von Feststoffen als Gärsubstrat sowie ihre Akzeptanz bei Biogasanlagenbetreibern heraus. Die Ergebnisse zeigen, dass die Feststoffe als Gärsubstrat bisher wenig Bedeutung haben. Ihr Einsatz wird mit steigendem Maispreis aber attraktiver, denn die Wirtschaftlichkeit der Güllefeststoffvergärung ist eine bedeutende Entscheidungsdeterminante. Ferner zeigt sich, dass sich bereits ein größerer Teil der Anlagenbetreiber mit der Güllefeststoffvergärung beschäftigt; bei einem kleinen Teil liegen sogar konkrete Pläne dazu vor.

Der Bezug von Verbrauchern zu Agrobiodiversität – Grundlagen für eine zielgruppengerechte Kommunikation

Publisher: name: Bundesministerium für Ernährung und Landwirtschaft
Year: 2014

description: Der Bezug von Verbrauchern zum Thema Agrobiodiversität ist weitgehend unklar. In der öffentlichen Diskussion sind sowohl der Begriff als auch die Inhalte kaum präsent. Mit der vorliegenden qualitativen Studie wurde erforscht, wie die Präsenz des Themas verbessert und eine verbrauchergerechte Kommunikation von Agrobiodiversität gestaltet werden kann. Die Ergebnisse zeigen, dass zum einen der Begriff "Agrobiodiversität" nicht für die Verbraucherkommunikation geeignet ist, zum anderen der inhaltliche Aspekt des "Erhaltens durch Nutzung" von vielen Verbrauchern nicht unmittelbar verstanden wird.

Vor allem den Konsum alter, seltener Pflanzensorten oder Fleisch bedrohter Rassen nehmen viele Verbraucher als kontraproduktiv für deren Erhalt wahr und lehnen ihn somit ab. Als inhaltliche Schwerpunkte für die Vermittlung des Themas an Konsumenten wurden unter anderem Regionalität, Geschmack und Verantwortung identifiziert. Aus den Ergebnissen lassen sich Empfehlungen hinsichtlich einer verbrauchergerechten Kommunikation ableiten: Sprache und Inhalte von Kommunikationsmedien sollten an Verbraucherwissen und -einstellungen angepasst sein; für eine erhöhte Aufmerksamkeit für das Thema Agrobiodiversität sollten zudem geeignete Kommunikationskanäle und -medien gewählt werden. Die Verbesserung politischer Rahmenbedingungen kann dabei zu einer verbesserten öffentlichen Wahrnehmung von Agrobiodiversität beitragen.

What do lesbians do?: motherhood ideology, lesbian mothers and family law
Creators: name: Millbank, Jenni
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the application of ideologies of motherhood in the context of family law. The approach taken is to work from the ‘margins’ of motherhood, using the experience of lesbian mothers as a focal point, in order to explore the ‘centre’ of dominant discourse and ideologies of motherhood. Case law from Australia, Canada, the UK and the USA over the past 20 years is examined. These cases are used to explore the ways in which lesbian mothers are characterised as ‘bad mothers’, in order to ask what these configurations illuminate about the requirements of ‘good’ mothering. The cases used were primarily child custody decisions involving divorcing parents, but are supplemented with some welfare and adoption cases. The picture, or story, of lesbian mothers which emerges from the judgments is one of fear and horror - a mixture of claiming the foreignness of lesbians at the same time that ‘common sense’ assumptions about lesbian mothers abound. This ‘story’ is contextualised in the thesis with a discussion of the characterisation of lesbians in popular culture in the past 70 years, along with formulaic ‘types’ and narratives, and their presence in and parallels with the legal judgments are then explored. In part, this thesis asserts that rights based discourse has been unsuccessful in engaging the judiciary to any positive end for lesbian mothers in family law. A framework of mother archetypes is used in order to delve beneath the surface level of the judgments to deeper linking themes. These include such themes as requirements of maternal altruism and lack of agency, fear of maternal animality and fear of male dispensability in child rearing. All of these themes find links in feminist work on motherhood ideology in other contexts, and these commonalities are discussed in the conclusion.

description: We have carried out a 3D ideal-MHD (Magnetohydrodynamic) simulation to study the evolution of laser generated plasma plume in a moderate external magnetic field (0.13 T) oriented perpendicular to the flow direction of the plasma plume. The simulation shows that the plasma plume pushes the external magnetic field lines outward in the direction of the expansion. This leads to compression and bending of the magnetic field lines.The force resulting from the change in shape and the density of magnetic field lines opposes the expansion of the plume. An elliptic layer of shocked plasma is formed at the plasma/external field interface leaving a cavity in the plume core due to the outward expansion and the inertia of the plume. As the plasma pressure drops due to expansion, the imbalance between the magnetic energy and the internal energy results in the collapse of the cavity. These observations have striking similarities with the observations of the experiments [Phys. Plasmas 24, 033511 (2017)] performed recently to study the plasma plume expansion in the presence of an external transverse magnetic field. This similarity indicates that the physical mechanisms dominantly governing the plasma plume expansion in the moderate magnetic field are aptly described in the ideal MHD regime. The studies thus show that the laser generated plasma plume can be utilized to carry out interesting experiments on MHD phenomena in a simple laboratory set up.
Fragmentation of jets containing a prompt J$/ψ$ meson in PbPb and pp collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV

description: Jets containing a prompt J$/ψ$ meson are studied in lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV, using the CMS detector at the LHC. Jets are selected to be in the transverse momentum range of 30 $\lt$ $p_\mathrm{T}$ $\lt$ 40 GeV. The J$/ψ$ yield in these jets is evaluated as a function of the jet fragmentation variable $z$, the ratio of the J$/ψ$ $p_\mathrm{T} $ to the jet $p_\mathrm{T}$. The nuclear modification factor, $R_\mathrm{AA}$, is then derived by comparing the yield in lead-lead collisions to the corresponding expectation based on proton-proton data, at the same nucleon-nucleon center-of-mass energy. The suppression of the J$/ψ$ yield shows a dependence on $z$, indicating that the interaction of the J$/ψ$ with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the J$/ψ$ meson.

description: Saturable and reverse saturable absorption at longitudinal surface plasmon resonance (SPR) in gold nanorods (Au NRs) have been observed using Z-scan and transient absorption techniques with femtosecond laser pulses. At lower excitation irradiances, the wavelength dispersion of saturable absorption has been determined near the longitudinal mode of SPR with a recovery time determined to be a few ten picoseconds on the SPR resonance. With higher excitation irradiances, reverse saturable absorption occurs and becomes dominant. The underlying mechanisms are discussed. Such reversible saturable absorption makes Au NRs an ideal candidate for optical limiting applications.

description: The present study investigates the contribution of religious education in school to the thorough development of students. It attempts to establish and assess the student’s character and integrated development course, along with the role played by religious education in school, education in general and education agents. First, the content of the key concepts and directions of education is investigated against the relevant scientific attitudes and contemporary trends in the Institute of Education. Then, the individual aspects of the student’s existential attitude along with his/ her development are studied on the basis of the approaches of leading scientists from the field of pedagogy and other disciplines as well. At the same time, the means, by which the religious education in school helps shape such attitudes, are presented; while pointing out ways to achieve a comprehensive and effective education. After that, the relation between development and extracurricular environment is investigated, by exhibiting the impact of the dynamics of each education agent on the student’s overall development. The present study eventually concludes with a report of the findings and the relevant literature.
Kreuzungsversuche mit Jersey-Rindern und deren Nutzung in Deutschland aus historischer Sicht

description: Vor etwa 90 Jahren wurde in Deutschland begonnen, erste experimentelle Arbeiten zur Kreuzung von Deutschen Schwarzbuntrindern mit Jerseys an der Universität in Halle/Saale durchzuführen. Sie wurden später ein wesentlicher Forschungsansatz im neuen Kaiser-Wilhelm-Institut in Dummerstorf (bei Rostock) vor 75 Jahren.
Entsprechende experimentelle Arbeiten wurden nach dem 2. Weltkrieg sowohl in West- als auch Ostdeutschland systematisch fortgesetzt.

In Ostdeutschland mündeten die vielfältigen Aktivitäten in dem Versuch, eine spezifische jerseyblütige schwarzbunte Milchrinderrasse (SMR) zu züchten.
Detaillierte Auswertungen zeigen das Auftreten von merkmalsspezifischen Heterosiseffekten. Auch belegen verschiedene Arbeiten das Auftreten von Rekombinationseffekten in späteren Kreuzungsstufen (R1-, F2-Generation) oder in der Stufe der In-Sich-Züchtung des SMR (= SMR x SMR).

Im Hinblick auf Empfehlungen zur Anwendung einer Kreuzungszucht bei Milchrindern genügt es somit nicht, ausschließlich eine F1-Generation gegenüber ihren reinrassigen Eltern zu bewerten. Zusätzlich ist festzuhalten, dass neuere Versuche mit Jerseykreuzungen gleichzeitig auch Genotyp-Umwelt-Interaktionen für Milchleistungsmerkmale in Abhängigkeit vom Produktionsniveau erkennen lassen.

Insgesamt haben die vielfältigen Studien zur Kreuzung von Schwarzbunten mit Jerseys in Deutschland schließlich mit dazu beigetragen, dass neuere züchtungsmethodische Ansätze auch beim Rind überprüft und verifiziert werden konnten.

description: RELIANCE, short for Research Lifecycle Management for Earth Science Communities and Copernicus users in EOSC, aims to realize the vision of FAIR research in EOSC by adopting a holistic research management approach based on three key and complementary technologies: i) Research objects (RO) as the overarching mechanism to manage scientific research activities, which relies upon ROHub platform as the reference service; ii) data cubes as the mechanisms enabling an efficient and scalable Earth Observation data access and discovery, which relies upon the Advanced geospatial Data Management (ADAM) platform as the reference service; iii) text mining and semantic enrichment services allowing to extract machine-readable metadata from RO resources, enabling researchers to discover scientific information at scale and to structure their own research, and which rely on the AI-based platform COGITO as base system. As part of the integration in EOSC, RELIANCE services will leverage and integrate with some of the EOSC core-cross cutting and added value services, playing a complementary role to what is already available and bridging between various EOSC services. RELIANCE will pilot the services in three different Earth Science communities, fostering the use of Copernicus data and demonstrating their efficacy in real-life vertical and multi-disciplinary scenarios, and will launch an Open Call to engage other communities. This document comprises the project management handbook. It contains all related information for running the RELIANCE project, including an introduction to the project and an overview of the rationale and the objectives. The main part of the document summarizes the information regarding the project management, structures and procedures, including some useful information from the Grant Agreement and its annexes, the Consortium Agreement and further decisions within the Consortium. RELIANCE partners will use this handbook as a reference manual during the implementation of their actions. The handbook will facilitate the management of the project, the monitoring of the overall progress and the communication between project partners and the Commission. Accordingly, it also provides the relevant information about the collaboration and communication tools, the organization and management of the meetings, and the timely and quality production of the planned deliverables.

description: In this work, we define and calculate critical exponents associated with higher order thermodynamic phase transitions. Such phase transitions can be classified into two classes: with or without a local order parameter. For phase transitions involving a local order parameter, we write down the Landau theory and calculate critical exponents using the saddle point approximation. Further, we investigate fluctuations about the saddle point and demarcate when such fluctuations dominate over saddle point calculations by introducing the generalized Ginzburg criteria. We use Wilsonian RG to derive scaling forms for observables near criticality and obtain scaling relations between the critical exponents. Afterwards, we find out fixed points of the RG flow using the one-loop beta function and calculate critical exponents about the fixed points for third and fourth order phase transitions.

description: Η παρούσα διατριβή επικεντρώθηκε στην αστική και περι-αστική γεωργία με έμφαση στην περίπτωση μελέτης του Αγροκτήματος της Γεωπονικής Σχολής Α.Π.Θ. Εξαιρετική πρωτοβουλία αποτελεί ο λαχανόκηπος της Γεωπονικής Σχολής του Αριστοτελείου Πανεπιστημίου Θεσσαλονίκης ο οποίος δημιουργήθηκε προς όφελος των αστών της ευρύτερης περιοχής της Θεσσαλονίκης. Οι κύριοι στόχοι της διατριβής είναι να μελετήσει το προφίλ των καλλιεργητών και τη δυνατότητα τμηματοποίησης τους βάση συγκεκριμένων μεταβλητών. Για την διερεύνηση των απαντήσεων χρησιμοποιήθηκαν επιστημονικές μέθοδοι. Αρχικά έγινε μια περιγραφική στατιστική ανάλυση, στη συνέχεια ανάλυση της συμβολής της εξαρτημένης μεταβλητής επί των ανεξάρτητων μεταβλητών με την μέθοδο της κατηγορικής παλινδρόμησης και τέλος επιλέχθηκε για τη στατιστική τμηματοποίηση των αστών καλλιεργητών σε δεδομένες διακριτές ομάδες (συστάδες) η μέθοδος της διβηματικής ανάλυσης σε συστάδες (two step cluster analysis), η οποία αποτελεί επέκταση της κλασικής ανάλυσης σε συστάδες και χρησιμοποιείται όταν κάποιες από τις μεταβλητές δεν είναι αριθμητικές (ισοδιαστημάτων ή αναλογικές) ή υπάρχει υπόθεση ότι οι σχέσεις μεταξύ των μεταβλητών δεν είναι γραμμικές.
description: The present study was focused in the urban and peri urban agriculture with emphasis in the case of study of Farm of Agriculture Faculty A.U.TH. Excellent initiative constitutes the vegetable garden of the Agriculture Faculty of Aristotelian University of Thessaloniki, whom was created for the benefit of the citizens, in the wider region of Thessaloniki. The main objectives, the present study, are to study the profile of farmers and their ability segmentation based on specific variables. To investigate the answers were used scientific methods. Initially there was a descriptive statistical analysis, afterwards analysis of contribution of made dependent variable on the independent variables with the method of categorical regression and finally it was selected for the statistical segmentation of city farmers in given distinct groups (clusters), the method of two-step analysis in clusters (two step cluster analysis), which constitutes extension of classic analysis in clusters and is used when some of the variables are not numeric (equal intervals or proportional) or there is a case that the relations between the variables are not linear.

description: Learning to classify time series with limited data is a practical yet challenging problem. Current methods are primarily based on hand-designed feature extraction rules or domain-specific data augmentation. Motivated by the advances in deep speech processing models and the fact that voice data are univariate temporal signals, in this paper, we propose Voice2Series (V2S), a novel end-to-end approach that reprograms acoustic models for time series classification, through input transformation learning and output label mapping. Leveraging the representation learning power of a large-scale pre-trained speech processing model, on 30 different time series tasks we show that V2S performs competitive results on 19 time series classification tasks. We further provide a theoretical justification of V2S by proving its population risk is upper bounded by the source risk and a Wasserstein distance accounting for feature alignment via reprogramming. Our results offer new and effective means to time series classification.

description: A semi-analytic approach to the computation of the non-linear power-spectrum of dark matter density fluctuations is proposed. The method is based on the Renormalization Group technique and can be applied to any underlying cosmological model. Our prediction on the baryonic acoustic oscillations in a LambdaCDM model accurately fits the results of N-body simulations down to zero redshift, where perturbation theory fails.

description: Pseudo-Newtonian gravitational potential describing the gravitational field of static and spherically symmetric black holes in the universe with a repulsive cosmological constant is introduced. In order to demonstrate the accuracy of the pseudo-Newtonian approach, the related effective potential for test-particle motion is constructed and compared with its general relativistic counterpart given by the Schwarzschild-de Sitter geometry. The results indicate that such an approach could be useful in applications of developed Newtonian theories of accretion discs in astrophysically interesting situations in large galactic structures for the Schwarzschild-de Sitter spacetimes with the cosmological parameter y=(1/3)ΛM^2<10^{-6}.

description: Η παρούσα μεταπτυχιακή διατριβή εξετάζει την υδρολογική λεκάνη του Μαΐστρου στην Αλεξανδρούπολη. Από την επεξεργασία των φύλλων χάρτη της Γεωγραφικής Υπηρεσίας Στρατού, σε κλίμακα 1 προς 50000, της Αλεξανδρούπολης, της Αισίμης και της Μαρωνείας εξήχθησαν τα απαιτούμενα δεδομένα. Η επεξεργασία αυτή έγινε με την χρήση ενός Γεωγραφικού Συστήματος Πληροφοριών. Τα εξαγόμενα στοιχεία και τα βροχομετρικά δεδομένα που μας δόθηκαν μετατράπηκαν σε ασαφείς αριθμούς με συγκεκριμένες αποκλίσεις. Έτσι προχωρήσαμε στον υπολογισμό της παροχής του Μαΐστρου με τον τύπο της ορθολογιστικής μεθόδου με τη βοήθεια της ασαφούς λογικής και για περίοδο επαναφοράς 50 ετών. Έπειτα υπολογίστηκε το ομοιόμορφο βάθος στο τελευταίο τμήμα των 2 χιλιομέτρων της διαδρομής του Μαΐστρου θεωρώντας το ομοιόμορφο βάθος ως ασαφή αριθμό και χρησιμοποιώντας τη Μέθοδο των Ακραίων Σημείων. Τέλος παρουσιάζουμε τα τελικά συμπεράσματα της παρούσας διατριβής. Πραγματοποιούνται υπολογισμοί με συμβατικούς αριθμούς και τα αποτελέσματα συγκρίνονται με αυτά που προέκυψαν από τη χρήση της ασαφούς λογικής. Επίσης αναλύονται οι αποκλίσεις που προέκυψαν στα ζητούμενα μεγέθη, όπως ο χρόνος συγκέντρωσης, η ένταση της βροχόπτωσης, η παροχή και το ομοιόμορφο βάθος.
description: The current thesis examines the river basin of Maistros in Alexandroupoli. The first step was to digitize the map sheets of the Geographical Army Service in scale 1:50000, of Alexandroupoli, Aisimi and Maronia and export the required data. This process was done by using a Geographic Information System. The exported geographical data and rainfall data we obtained were converted into fuzzy numbers with specific deviations. Then we proceeded to the estimation of the water supply of Maistros using the rational method and the fuzzy logic method for recurrence interval of 50 years. After that we calculated the crucial depth in the last part of the 2 km path of Maistros, assuming that the crucial depth is a fuzzy number and using the Vertex Method. Finally we present the final conclusions of this thesis. Calculations are performed with crispy numbers and the results are compared with those obtained by using the fuzzy logic method. Also the deviations of the calculated numbers, such as the time of concentration, intensity of rainfall, the flow and uniform depth, are analyzed.
