description: Οι δασικές πυρκαγιές αποτελούν ένα φαινόμενο που συγκαταλέγεται στις φυσικές καταστροφές. Τα τελευταία χρόνια αποτελούν έναν από τους πιο σοβαρούς κινδύνους για τα δάση της Μεσογείου, και κατ’ επέκταση της Ελλάδας, ενώ έχουν υπάρξει αντικείμενο αυξανόμενου ενδιαφέροντος κατά τις τελευταίες δεκαετίες σε παγκόσμια κλίμακα. Οι επιπτώσεις τους στο τοπίο, την κοινωνική ευημερία και το περιβάλλον είναι ήδη τεράστιες. Το φαινόμενο αυτό, σε συνδυασμό με την επίδραση που ασκεί και, παράλληλα, δέχεται από την κλιματική αλλαγή πρόκειται να προκαλέσει αύξηση της δριμύτητας και τη γεωγραφική επέκταση των περιοχών υψηλού κίνδυνου. Για την αντιμετώπισή του κρίνεται απαραίτητη η ορθολογική διαχείριση των δασικών πυρκαγιών. Οι δασικές πυρκαγιές χαρακτηρίζονται ως φαινόμενο που αναπτύσσεται και εξελίσσεται σε χωρική και χρονική κλίμακα. Επομένως, είναι αναγκαία η συστηματική διαχείριση δασικών εκτάσεων με την βοήθεια των Συστημάτων Γεωγραφικών Πληροφοριών. Με τη σωστή διαχείριση θα δημιουργηθούν οι κατάλληλες συνθήκες για ένα δάσος περισσότερο υγιές, οδηγώντας αυτόματα στη μείωση της πιθανότητας πυροδότησης φωτιάς, αλλά κυρίως στην εξασφάλιση της μειωμένης δριμύτητας της, επομένως και τον έλεγχό της. Με αυτό τον τρόπο δεν θα επιτύχουμε μόνο την προστασία από τις δασικές πυρκαγιές, αλλά και την αξιοποίηση των δασικών εκτάσεων. Αυτό στο οποίο αποβλέπουμε είναι ένα περιβάλλον ελεγχόμενων και μη καταστρεπτικών πυρκαγιών, καθώς και στη συνεργασία των ανάλογων φορέων όσον αφορά στη διαχείρισή τους
description: Forest fires are a phenomenon among the natural disasters. In recent years they are one of the most serious risks to the forests of the Mediterranean, and by extension Greece and have been the subject of increasing interest in recent decades worldwide. Their impact on the landscape, social welfare and the environment are already enormous. This phenomenon, in combination with its influence that force and at the same time receive from climate change will cause an increase in severity and geographic expansion of high-risk areas. The rational management of forest fires is necessary to address this. Forest fires are characterized as a phenomenon that develops and progresses to spatial and temporal scale. Therefore, it is necessary to systematically manage forest lands with the help of GIS. With the right management will create the conditions for a forest healthier, automatically leading to reduced probability of fire initiation, but mainly to ensure the reduced severity, and therefore its control This way we will not only achieve the protection against forest fires, but the utilization of forest land. What we aspire to is an environment of controlled and non-destructive fires, and the cooperation of relevant agencies in terms of their management

description: We study Zeeman splitting of zone-center subband edges in a cylindrical hole wire subject to a magnetic field parallel to its axis. The g-factor turns out to fluctuate strongly as a function of wire-subband index, assuming values that differ substantially from those found in higher-dimensional systems. We analyze the spin properties of hole-wire states using invariants of the spin-3/2 density matrix and find a strong correlation between g-factor value and the profile of hole-spin polarization density. Our results suggest possibilities for confinement engineering of hole spin splittings.

Drift capacity models for modern URM walls for EC8 Part 1
Creators: name: Beyer, Katrin

Publisher: name: Zenodo
Year: 2022

description: This objective of this report was to put forward drift capacity models for the revised Eurocode 8, Part 1 (EC8-Part 1). For this purpose, it reviews the data available on quasi-static cyclic tests on masonry walls in the recently assembled European database for URM walls. Based on this review, it proposes two simple drift capacity models. Both models account for the unit typology. In addition, Model 1 accounts for the failure mode and follows therefore the traditional form for URM drift capacity models. Unlike the current drift capacity model in the current EC8-Part 3 [2], it introduces an axial load ratio limit of 0.3. Walls subjected to higher ALR should be avoided; if this is not possible, it should be assumed that they have only one third of the drift capacity of walls with ALR ≤ 0.3. Note that the idea of an ALR-limit is already included in the German national annex to Eurocode 8 [38] for walls failing in shear. It limits the SD drift capacity of 0.4%, which is specified in the current EC8-Part 3, to walls with an ALR ≤ 0.15. For walls with a larger ALR, the drift capacity is reduced to 0.3%. All files, from the extraction of the data from the data bases to the files for plotting the figures are publicly shared. A file register describing the content of the files is included at the end of each chapter of the report.
description: Changes with regard to V1.1: 1) Further analyses on the size effect are added; 2) A third drift capacity model, which is a function of the failure mode, the axial load ratio and the unit type is added; 3) The input data is not only shared in mat-format but also in xlsx-format (b: xlsx-file added).

The meaning and experience of body image : women feeling comfortable with their bodies
Creators: name: Tempest, Maureen
Publisher: name: University of British Columbia
Year: 2008

description: A qualitative phenomenological paradigm was utilized to explore the experience and meaning of body image for women feeling comfortable with their bodies. Seven women who felt comfortable with their bodies participated in this study. During individual, in-depth interviews, which were audio-taped, the women described their experience of bodily comfort past and present. The women reported that they experienced becoming comfortable with themselves and their bodies as a developmental process. Five common themes were extrapolated from the data using a thematic analysis procedure devised by Colaizzi (1978). The themes describe the women's experiences of feeling personal validation, of developing increased self worth, of integrating all aspects of themselves, of rejecting some external standards for appearance and behavior, and developing a sense of being at home in their bodies.

description: This dissertation investigates the corruption phenomenon, checking its latest literature meanings and comparing the most recent statistical data, regarding corruption indexes for the Greek case. The dissertation starts with a wider literature overview of the conceptual interpretation of corruption. The corresponding scientific categories and corruption types are quoted, along with the corruption models and causes as well as the areas where corruption is found. Next, the differences of the corruption phenomenon between the public and the private sector are analyzed. The next section of the dissertation cites the existing anti-corruption policies, as indicated by the latest literature tendencies. A detailed analysis of Greek corruption levels takes place later on the dissertation, quoting the levels of the indexes that are most scientifically valid. At the same time, a comparison between the Greek corruption levels and the timeless Greek economic levels is undertaken. The dissertation ends with the research conclusions and the proposed anti-corruption policies

description: This paper explores the stability of an Earth-like planet orbiting a solar-mass star in the presence of a stellar companion using ~ 400,000 numerical integrations. Given the chaotic nature of the systems being considered, we perform a statistical analysis of the ensuing dynamics for ~500 orbital configurations defined by the following set of orbital parameters: the companion mass; the companion eccentricity; the companion periastron; and the planet's inclination angle relative to the stellar binary plane. Specifically, we generate a large sample of survival times for each orbital configuration through the numerical integration of N >> 1 equivalent experiments (e.g., with the same orbital parameters but randomly selected initial orbital phases). We then construct distributions of survival time using the variable mu_s = log tau_s (where tau_s is in years) for each orbital configuration. The primary objective of this work is twofold. First, we use the mean of the distributions to gain a better understanding of what orbital configurations, while unstable, have sufficiently long survival times to make them interesting to the study of planet habitability. Second, we calculate the width, skew, and kurtosis of each mu_s distribution and look for general features that may aid further understanding and numerical exploration of these chaotic systems.

description: Having in mind extensions of 2D holography beyond the Jackiw-Teitelboim model we propose holographic counterterms and asymptotic conditions for a family of asymptotically AdS$_2$ dilaton gravity models leading to a consistent variational problem and a finite on-shell action. We show the presence of asymptotic Virasoro symmetries in all these models. The Schwarzian action generates (a part) of the equations of motion governing the asymptotic degrees of freedom. We also analyse the applicability of various entropy formulae. By a dilaton-dependent conformal transformation our results are extended to an even larger class of models having exotic asymptotic behavior. We also analyse asymptotic symmetries for some other classes of dilaton gravities without, however, constructing holographic counterterms.

description: This dissertation attempts to make an overview of European cultural policies, their role in integration process and the importance of European journalistic reporting in this direction. By examining in detail, the research on these matters the last few decades, we present a literature overview of the aforementioned topics. The aim of this dissertation is to examine the way cultural policies can foster the integration process and enhance the links between European Union and European citizens by reinforcing a sense of common cultural identity and cultural citizenship. In the current, rather ominous European environment, the EU cultural programs can pave the way for a more integrated Europe by showcasing that European identity does not entail an antagonism between national and European identity but the creative interaction and cross-fertilization of the different cultural identities and traditions

Αναλύοντας με λεπτομέρεια την έρευνα στα παραπάνω θέματα τις τελευταίες δεκαετίες, παρουσιάζουμε μια βιβλιογραφική επισκόπηση των ζητημάτων αυτών. Ο στόχος αυτής της διπλωματικής εργασίας είναι να εξετάσει τους τρόπους με τους οποίους οι πολιτιστικές πολιτικές μπορούν να βοηθήσουν στη διαδικασία της ευρωπαϊκής ολοκλήρωσης και να βελτιώσουν τη σύνδεση μεταξύ της Ευρωπαϊκής Ένωσης και των πολιτών της ενισχύοντας την αίσθηση μιας κοινής πολιτιστικής ταυτότητας και πολιτιστικής ιθαγένειας. Στο σημερινό, μάλλον δυσοίωνο ευρωπαϊκό περιβάλλον, τα ευρωπαϊκά πολιτιστικά προγράμματα μπορούν να ανοίξουν τον δρόμο για μια πιο ενοποιημένη Ευρώπη, προβάλλοντας ότι η ευρωπαϊκή ταυτότητα δεν συνεπάγεται τον ανταγωνισμό μεταξύ εθνικής και ευρωπαϊκής ταυτότητας, αλλά τη δημιουργική αλληλεπίδραση και διασταύρωση των διαφορετικών πολιτιστικών ταυτοτήτων και παραδόσεων

description: Fra gli ultimi decenni dell’800 e i primi del ‘900 un vasto gruppo di intellettuali attivi in differenti campi (letteratura, filosofia, sociologia, critica letteraria, critica artistica, ecc.) imposta il proprio discorso sulla base di rigide coppie binomiali (la più famosa e duratura è quella concernente i concetti di Kultur e Zivilisation) tese a differenziare su principi giustappostivi e a-dialettici due campi d’indagine sempre in radicale contrasto. Benché lo schema interpretativo si adatti a settori quanto mai eterogenei (siano queste le conformazioni consociative ‘comunità’ e ‘società’ in Ferdinand Tönnies, le espressioni artistiche di Rinascimento e Barocco di Heinrich Wölfflin, i concetti di ‘anima’ e ‘forma’ del giovane Lukács o quelli di Riforma e Controriforma del Malaparte fascista, ecc.) le caratteristiche assegnate ai rispettivi termini del binomio si ripetono pressoché identiche da un’analisi all’altra. Dove uno dei termini risulta legato alla catena metonimica dell’Essere e ai concetti di universalità, saldezza, rigidità, unità, ecc., il secondo riferisce alla sfera del particolare, dell’apparenza, della disgregazione, della fluidità, ecc. L’articolo analizza, seguendo alcuni esempi, tanto l’espressione di questa cultura quanto le ragioni del suo formarsi in opposizione allo sviluppo e poi all’egemonia della cosiddetta ‘filosofia della crisi’. Between the last decades of the XIXth century and the first years of the XXth century, several European intellectuals active in different fields (literature, philosophy, sociology, literary critic, art history, etc.) develop a discourse based on rigid dichotomies (the most famous of which is the one regarding the concepts Kulturand Zivilisation) aimed at differentiating, on non dialectical principles, two cultural fields always in radical contrast. Although the same scheme is applied to very different intellectual grounds (the social conformations of ‘community’ and ‘society’ in Ferdinand Tönnies, the artistic expressions of Renaissance and Baroque in Heinrich Wölfflin, the concepts of ‘soul’ and ‘form’ in the young Lukács, or those of Reformation and Counterreformation in the fascist intellectual Curzio Malaparte, etc.) the features attributed to the respective elements of the dichotomiesrepeated across the different analyses. If one the two elements is related to the idea of Being and to the concepts of universality, firmness, rigidity, unity, etc., the second one refers to the particularity, the appearance, the disaggregation, the fluidity, etc.My article analyzes, following several examples, both the manifestation of this culture and the reasons behind its formation.

description: We analyze about 12 years of Fermi-LAT data in the direction of the Andromeda galaxy (M31). We robustly characterize its spectral and morphological properties against systematic uncertainties related to the modeling of the Galactic diffuse emission. We perform this work by adapting and exploiting the potential of the skyFACT adaptive template fitting algorithm. We reconstruct the gamma-ray image of M31 in a template-independent way, and we show that flat spatial models are preferred by data, indicating an extension of the $γ$-ray emission of about 0.3-0.4 degree for the bulge of M31. This study also suggests that a second component, extending to at least 1 degree, contributes to the observed total emission. We quantify systematic uncertainties related to mis-modeling of Galactic foreground emission at the level of 2.9%.

description: In a two-dimensional version of the modified Hasegawa-Wakatani (HW) model, which describes electrostatic resistive drift wave turbulence, the resistive coupling between vorticity and density does not act on the zonal components ($k_{y}=0$). It is therefore necessary to modify the HW model to treat the zonal components properly. The modified equations are solved numerically, and visualization and analysis of the solutions show generation of stable zonal flows, through conversion of turbulent kinetic energy, and the consequent turbulence and transport suppression. It is demonstrated by comparison that the modification is essential for generation of zonal flows.

description: The goal of this thesis was to create a system that would train an unmanned aircraft vehicle, drone as it is commonly called, to follow a cyclist. The drone is part of the AirSim simulator and the cyclist is a creation on the environment of the Unreal Engine. For the training, a Deep Reinforcement Learning algorithm was used. The solution to the problem was based on Microsoft's Autonomous Driving Cookbook project. This paper provides information on unmanned aircraft vehicles and their impact on our society. Also, Reinforcement Learning, a problem solving technique of Machine Learning, has been analyzed, providing details of how it works, its algorithm and its applications. Next, there is an overview of the basics of the AirSim simulator and how it can be used in Reinforcement Learning experiments. Finally, a description of the experiment has been given, its solution, its results and some conclusions
Quasimodo and the Spiritualization of Cruelty, Saba’s Uncanny Shortcuts, Montale’s Grotesque Imaginary: Complex Genealogies of Italian Poetry on the Jewish Genocide
Creators: name: Pepe, Tommaso

Year: 2019
Subjects: Shoah; Saba; Quasimodo; Spiritualization of Cruelty; Uncanny

description: The memory of anti-Jewish persecution intersected the work of prominent authors in Italian twentieth century poetry, often following oblique and unexpected trajectories that touch authors such as Montale, Sereni, Fortini, Pasolini, Saba, Levi, Quasimodo. This essay intends to probe a genealogical juncture in this poetic history, bringing into purview a series of poliperspectival models of poetic writing about the Shoah elaborated by Salvatore Quasimodo, Umberto Saba and Eugenio Montale in the early postwar years. If Quasimodo’s poesia civilepaved the way to a literary monumentalization of memory, such poetic configuration ultimately might be seen to hinge on what Friedrich Nietzsche critically termed a “spiritualization of cruelty.” Thus it was progressively identified as a potential anti-model for Italian poetry dealing with the memory of the persecution – as a reading of Montale’s treatment of this theme reveals. On the other hand, Saba condesned his afterthoughts about the “cannibalism” of racial persecution in Scorciatoie e raccontini(Shortcuts and Very Short Stories): a book of poèmes en prosethat possesses “the accent of poetry and the rigor of aphorism.” These uncanny and ironical shortcuts raise corrosive doubts about the value attached to a purported monumental memory of the Shoah and bring to attention the existence of genealogical complexity in Italian poetic writing about the Jewish genocide that calls for adequate critical recognition.

description: Il saggio si propone di riprendere la questione della narratività in relazione alle prime due opere finzionali di Giorgio Manganelli: Hilarotragoedia e Nuovo commento. Il primo paragrafo discute la classica definizione di Manganelli come scrittore antinarrativo, ripercorrendo alcune delle principali prese di posizione dell’autore contro il genere romanzesco e più in generale intorno al concetto di narrazione. Il secondo paragrafo legge alcuni passi dei due libri di Manganelli sulla scorta della teoria delle forme temporali proposta da Harald Weinrich in Tempus. Besprochene und erzählte Welt. L’ultimo paragrafo mette a fuoco alcune conseguenze dell’applicazione della teoria di Weinrich a questo contesto, concentrandosi in particolare sull’uso dinamico che Manganelli fa della figura dell’evidentia, utilizzata come una strategia nascosta di fabulazione narrativa. The main purpose of this essay is to reconsider the problematic issue of narrativity in Giorgio Manganelli’s earliest fictional works: Hilarotragoediaand Nuovo commento. The first paragraph debates the classic definition of Manganelli as an antinarrative writer and reexamines the main positions of the author against the novel and around the concept of narration in general. The second paragraph provides an interpretation of Manganelli’s fictional treatises through Harald Weinrich’s theory as outlined in Tempus. Besprochene und erzählte Welt. The last paragraph tries to draw some conclusions from the application of Weinrich’s theory to this context and focuses on Manganelli’s dynamic use of ecphrasis as a hidden strategy of narration.

description: With increasing advancements in technologies for capturing 360° videos, advances in streaming such videos have become a popular research topic. However, streaming 360° videos require high bandwidth, thus escalating the need for developing optimized streaming algorithms. Researchers have proposed various methods to tackle the problem, considering the network bandwidth or attempt to predict future viewports in advance. However, most of the existing works either (1) do not consider video contents to predict user viewport, or (2) do not adapt to user preferences dynamically, or (3) require a lot of training data for new videos, thus making them potentially unfit for video streaming purposes. We develop PARIMA, a fast and efficient online viewport prediction model that uses past viewports of users along with the trajectories of prime objects as a representative of video content to predict future viewports. We claim that the head movement of a user majorly depends upon the trajectories of the prime objects in the video. We employ a pyramid-based bitrate allocation scheme and perform a comprehensive evaluation of the performance of PARIMA. In our evaluation, we show that PARIMA outperforms state-of-the-art approaches, improving the Quality of Experience by over 30\% while maintaining a short response time.

La monofagia del moderno egoista. Servitù e ‘vita activa’ in Leopardi
Creators: name: D'Intino, Franco
Publisher: name: ENTHYMEMA
Year: 2019
Subjects: Servitù; Schiavitù; Consumo del cibo; G. Leopardi; J.-J. Rousseau; H. Arendt; Servitude; Slavery; Food Consumption

description: Il saggio prende spunto da un ricordo d’infanzia annotato nello Zibaldoneil 26 marzo 1820, che Leopardi rubrica sotto la voce “Servitori”. A partire da questo appunto, il contributo indaga la presenza del motivo della servitù, e del rapporto servo-padrone, nel diario leopardiano e nei ricordi autobiografici raccolti nella Vita abbozzata di Silvio Sarno, intrecciandolo dapprima con le considerazioni rousseauiane sul tema (Émile e Confessions) e poi con il concetto arendtiano di ‘vita activa’. Attraverso l’analisi di temi (la schiavitù, il pubblico e il privato, il consumo alimentare, l’egoismo) e di figure emblematiche (il domestico, il tiranno, il monofago, il viaggiatore solitario), il saggio mostra le implicazioni autobiografiche, storiche (l’«umanità degli antichi») e filosofiche dell’interesse leopardiano per il motivo della servitù: la desolata presa d’atto che la società moderna condivide con la natura un inevitabile egoismo, nella misura in cui il bisogno del singolo prevale su valori durevoli e pubblici come la gloria e l’onore. The essay starts from a childhood memory recorded in Zibaldone the 26th of May 1820, indexed under the heading “Servants.” It explores the theme of “servitude” (servitù, or schiavitù, “slavery”), and the relationship master/slave in the Zibaldone and in the autobiographical memories known as Vita abbozzata di Silvio Sarno, relating them with Rousseau’s Émile and Confessions, and with Arendt’s concept of “vita activa.” Through the analysis of themes such as slavery, egoism, consumption, public/private, and of paradigmatic figures such as the servant, the tyrant, the solitary traveller and especially the “monophagous”, by which term Leopardi understands somebody who doesn’t like to eat in company, the essay shows the autobiographical, historical and philosophical implications of Leopardi’s interest in the issue of servitude, and in particular his disillusioned acknowledgement that modern society shares with nature egoism and selfishness, since individual commodities tend to prevail over values such as glory and honour.

description: We present upper limits on line emission in the Cosmic X-ray background (CXB) that would be produced by decay of sterile neutrino dark matter. We employ the spectra of the unresolved component of the CXB in the Chandra Deep Fields North and South obtained with the Chandra CCD detector in the E=0.8-9 keV band. The expected decay flux comes from the dark matter on the lines of sight through the Milky Way galactic halo. Our constraints on the sterile neutrino decay rate are sensitive to the modeling of the Milky Way halo. The highest halo mass estimates provide a limit on the sterile neutrino mass of m_s<2.9 keV in the Dodelson-Widrow production model, while the lowest halo mass estimates provide the conservative limit of m_s<5.7 keV (2-sigma). We also discuss constraints from a short observation of the softer (E<1 keV) X-ray background with a rocket-borne calorimeter by McCammon and collaborators.

description: The Stokes-Einstein (SE) relation is commonly regarded as being breakdown in supercooled water. However, this conclusion is drawn upon testing the validities of some variants of the SE relation rather than its original form, and it appears conflicting with the fact that supercooled water is in its local equilibrium. In this work, we show by molecular dynamics simulation that both the Einstein and Stokes relations are indeed conserved in supercooled water. The inconsistency between the original SE relation and its variants comes from two facts: (1) the substitutes of the shear viscosity in the SE variants are wavevector-dependent, so it is only a cursory approximation; (2) the effective hydrodynamic radius actually decreases with decreasing temperature, instead of being a constant as assumed in the SE variants. Besides supercooled water, this inconsistency may also exist in other supercooled liquids.

description: Σκοπός της διατριβής ήταν η μελέτη της χορήγησης της ηπαρίνης κατά τη διάρκεια των καρδιοχειρουργικών επεμβάσεων. Εξετάσαμε την ηπαρίνη ως προς την δράση, την φαρμακοκινητική, την εξουδετέρωσή της από την πρωταμίνη και κάποιες εναλλακτικές της πρωταμίνης στρατηγικές. Στη συνέχεια παρουσιάσαμε τις δόσεις χορήγησης και τους τρόπους μέτρησης της δράσης της καθώς και το φαινόμενο της αντίστασης στην ηπαρίνη. Ακόμα, αναφερθήκαμε αναλυτικά στον μειωμένο ηπαρινισμό που μπορεί να εφαρμοστεί σε ειδικές περιπτώσεις επικαλυμμένων κυκλωμάτων εξωσωματικής κυκλοφορίας και συστημάτων MiECC. Ένα άλλο θέμα που θίξαμε ήταν οι επιπλοκές από την χορήγηση της ηπαρίνης και ιδιαίτερα η θρομβοπενία. Ασχοληθήκαμε επιπλέον με τα εναλλακτικά της ηπαρίνης φάρμακα
description: The aim of the present thesis was the study of the administration of heparin during cardiovascular surgery. We examined the action of heparin, its pharmacokinetics, and its neutralization by protamine and some protamine’s alternatives. . Then we presented the administration doses, the heparin monitoring and heparin resistance. Furthermore, we analyzed the reduced anticoagulation that can be applied with the use of coated circuits of extracorporeal circulation and MiECC systems. Another aim of this study was to present heparin’s side effects and heparin’s alternatives

description: Measurements of both the inclusive and differential production cross sections of a top-quark-antiquark pair in association with a $Z$ boson ($t\bar{t}Z$) are presented. The measurements are performed by targeting final states with three or four isolated leptons (electrons or muons) and are based on $\sqrt{s} = 13$ TeV proton-proton collision data with an integrated luminosity of 139 fb$^{-1}$, recorded from 2015 to 2018 with the ATLAS detector at the CERN Large Hadron Collider. The inclusive cross section is measured to be $σ_{t\bar{t}Z} = 0.99 \pm 0.05$ (stat.) $\pm 0.08$ (syst.) pb, in agreement with the most precise theoretical predictions. The differential measurements are presented as a function of a number of kinematic variables which probe the kinematics of the $t\bar{t}Z$ system. Both absolute and normalised differential cross-section measurements are performed at particle and parton levels for specific fiducial volumes and are compared with theoretical predictions at different levels of precision, based on a $χ^{2}/$ndf and $p$-value computation. Overall, good agreement is observed between the unfolded data and the predictions.

description: Αντικείμενο της συγκεκριμένης εργασίας είναι η δημιουργία μιας εφαρμογής Επαυξημένης Πραγματικότητας (AR) για τον έλεγχο ενός Drone. Για το σκοπό αυτό χρησιμοποιείται το HMD μικτής πραγματικότητας Hololens της Microsoft. Μέσω κινήσεων των χεριών που αναγνωρίζονται από την κάμερα της συσκευής ο χρήστης στέλνει εντολές προς το Drone και ορίζει σημεία διαδρομής. Το σύστημα κάνοντας χρήση GPS συντεταγμένων μπορεί να ανιχνεύει τη θέση του Drone και να υπερθέτει την εικονική πληροφορία στο οπτικό πεδίο του χρήστη. Η δυνατότητα του Hololens να προβάλλει ολογράμματα στο χώρο επιτρέπει τη δημιουργία ενός ολογραφικού χάρτη του περιβάλλοντος μέσα στο οποίο κινείται το Drone. Επίσης το σύστημα ενσωματώνει στοιχεία εφαρμογών AR που συναντάμε σε εφαρμογές τουρισμού και πλοήγησης όπως ενδείξεις για σημεία ενδιαφέροντος και πληροφορίες για τη θέση του χρήστη, καθώς και ένα διαδραστικό παιχνίδι. Η λειτουργικότητα της εφαρμογής αξιολογήθηκε σε περιβάλλον προσομοίωσης σε υπολογιστή αλλά και σε εξωτερικό χώρο
description: The aim of this thesis is the development of an Augmented Reality (AR) application for Drone navigation. The system is developed for a Microsoft HoloLens head-mounted augmented reality display. Through hand gestures that the device’s camera recognizes the user can send commands to the drone and define waypoints. The system makes use of GPS coordinates to track the drone and overlay virtual information on the user’s field of view. Hololen’s ability to render 3D holograms is used to create a holographic map of the environment the drone moves in. The system also incorporates capabilities that are found in tourism and navigation applications like point of interest visualization and user location information, as well as an interactive game. The application was evaluated in a computer simulated environment as well as a real outdoors environment

description: This paper presents a technique called Improved Squeaky Wheel Optimisation for driver scheduling problems. It improves the original Squeaky Wheel Optimisations effectiveness and execution speed by incorporating two additional steps of Selection and Mutation which implement evolution within a single solution. In the ISWO, a cycle of Analysis-Selection-Mutation-Prioritization-Construction continues until stopping conditions are reached. The Analysis step first computes the fitness of a current solution to identify troublesome components. The Selection step then discards these troublesome components probabilistically by using the fitness measure, and the Mutation step follows to further discard a small number of components at random. After the above steps, an input solution becomes partial and thus the resulting partial solution needs to be repaired. The repair is carried out by using the Prioritization step to first produce priorities that determine an order by which the following Construction step then schedules the remaining components. Therefore, the optimisation in the ISWO is achieved by solution disruption, iterative improvement and an iterative constructive repair process performed. Encouraging experimental results are reported.

description: The complementarity and substitutability between products are essential concepts in retail and marketing. Qualitatively, two products are said to be substitutable if a customer can replace one product by the other, while they are complementary if they tend to be bought together. In this article, we take a network perspective to help automatically identify complements and substitutes from sales transaction data. Starting from a bipartite product-purchase network representation, with both transaction nodes and product nodes, we develop appropriate null models to infer significant relations, either complements or substitutes, between products, and design measures based on random walks to quantify their importance. The resulting unipartite networks between products are then analysed with community detection methods, in order to find groups of similar products for the different types of relationships. The results are validated by combining observations from a real-world basket dataset with the existing product hierarchy, as well as a large-scale flavour compound and recipe dataset.

description: Σκοπός της παρούσας διπλωματικής είναι η διερεύνηση της συσχέτισης μεταξύ της ελευθερίας της έκφρασης και του δημοσίου συμφέροντος στην Ελληνική και Ευρωπαϊκή έννομη τάξη σε αντίθεση με την συνταγματική ερμηνεία της 1ης Τροπολογίας του Αμερικανικού Συντάγματος από το Ανώτατου Δικαστηρίου των ΗΠΑ. Η συγκριτική επισκόπηση φανερώνει τις συγκλίσεις αλλά και τις διαφορές μεταξύ της ερμηνείας του δικαιώματος και του χώρου αναπνοής που η κάθε έννομη τάξη επιτρέπει στην ανάπτυξη του. Αντικείμενο ανάλυσης αποτέλεσε: α) το ζήτημα της κριτικής σε δημόσια πρόσωπα και η ανάπτυξη αντικειμενικών κριτηρίων για την επίλυση διαφορών που άπτονται της προσβολής της τιμής των προσώπων, β) η αντιμετώπιση των whistleblowers ή μαρτύρων δημοσίου συμφέροντος, υπό το πρίσμα της προστασίας τους από αντεκδικητικά μέτρα ως συνέπεια των αποκαλύψεων τους, στον δημόσιο τομέα και στους εργαζομένους σε υπηρεσίες πληροφοριών, γ) η καταστροφή των εθνικών συμβόλων με έμφαση στο ζήτημα της σημαίας, και κυρίως στις εμβληματικές, και ταυτόχρονα αμφιλεγόμενες, αποφάσεις του Ανώτατου Δικαστηρίου υπέρ της συνταγματικής προστασίας του δικαιώματος στην καταστροφή της εθνικής σημαίας ως μέρος του προστατευόμενου πολιτικού λόγου κατά την 1η Τροπολογία
description: The aim of the present dissertation is the inquiry into the correlation between the freedom of expression and public interest in the Greek and European legal order in contrast to the constitutional interpretation of the 1st Amendment of the American Constitution from the Supreme Court of the USA. Comparative analysis indicates the convergence and the differences between the interpretation of the right and the breathing space each legal order allows for its development. The subject matter of the analysis has been : a) the issue of criticism to public figures and the development of objective criteria for the resolution of disputes which concern the offence to the honor of individuals, b) the attitude towards whistleblowers or crown witnesses, under the scope of the protection from retaliatory measures as a consequence of their revelations, in the public sector and employees of intelligence services, c) the desecration of national symbols with stress placed upon the issue of the flag, and mostly to the iconic, and controversial at the same time, decisions of the Supreme Court in favor of the constitutional protection of the desecration of the national flag as protected political speech according to the 1st Amendment
