Πρόταση διαχείρισης και ανάδειξης των μνημείων της ευρύτερης περιοχής του Δύστου στη νότια Εύβοια

Η παρούσα διπλωματική εργασία με θέμα την «Πρόταση διαχείρισης και ανάδειξης των μνημείων της ευρύτερης περιοχής του Δύστου στη Νότια Εύβοια» εκπονήθηκε στο πλαίσιο ολοκλήρωσης του Δ.Π.Μ.Σ. «Διαχείριση Μνημείων: Αρχαιολογία, Πόλη, Αρχιτεκτονική». Παρατηρώντας την ελλιπή ανάδειξη του πολιτιστικού πλούτου στο νησί της Εύβοιας προτείνεται η ανάδειξη των ανθρωπογενων και φυσικών μνημείων γύρω από τη λίμνη του Δύστου και η δημιουργία θεματικών πολιτιστικών διαδρομών στην Κεντρική και τη Νότια Εύβοια. Σκοπός αυτής της προσπάθειας είναι να αξιοποιηθεί το σημαντικό πολιτιστικό απόθεμα του νησιού, το οποίο καταγράφηκε συστηματικά, συμβάλλοντας ποικιλοτρόπως στην ανάπτυξη της ευρύτερης περιοχής. Στο πρώτο μέρος γίνεται περιγραφή του αρχαιολογικού χώρου, των μνημείων, των ευρημάτων και του φυσικού τοπίου της Εύβοιας και πιο συγκεκριμένα της περιοχής του Δύστου. Για τον σκοπό αυτό γίνεται μια συνοπτική περιγραφή των ευρημάτων που έχουν εντοπιστεί κυρίως μέσω βιβλιογραφικής και επιτόπιας έρευνας. Στο δεύτερο μέρος γίνεται καταγραφή και παρουσίαση της σημερινής κατάστασης και διατήρησης του χώρου η οποία συνοδεύεται από φωτογραφικό υλικό. Στο επόμενο στάδιο της έρευνας γίνεται μια συνολική αξιολόγηση του χώρου και των δυνατοτήτων του και τέλος, προτείνονται ενδεχόμενες επεμβάσεις στη περιοχή βασιζόμενοι στα στοιχεία που προέκυψαν από την έρευνα με τη συνοδεία ψηφιακών αναπαραστάσεων.This thesis on the subject of "Cultural managment and designation of the monuments in the wider area of ancient Dystos in South Euboea" was devised in the context of the completing the master's degree "Management of Monuments: Archaeology, City, Architecture". Observing the emptiness of designation of the cultural heritage on the island of Euboea, highly recommended emergence the man-made and natural monuments around the Lake of Dystos and the creation of thematic cultural routes in Central and Southern Euboea. The purpose of this effort is to exploit the important cultural reserve of the island, which was systematically recorded, contributing to the development of the wider region. In the first part there is a description of the archaeological site, the monuments, the finds and the natural landscape of Euboea and more specifically the area of ​​Dystos. For this purpose, a summary description of the findings identified mainly through bibliographic and field research. The second part records and presents the current state and conservation of the area which is accompanied by photographic material. In the next stage of the research is made an overall "panoramic view" of the area and of its capabilities and finally, are proposed potential interventions area based on the data obtained from the survey accompanied by digital representations

Kinetic versus Magnetic Chaos in Toroidal Plasmas: A systematic quantitative comparison

Magnetic field line chaos occurs under the presence of non-axisymmetric perturbations of an axisymmetric equilibrium and is manifested by the destruction of smooth flux surfaces formed by the field lines. These perturbations also render the particle motion, as described by the guiding center dynamics, non-integrable and, therefore, chaotic. However, the chaoticities of the magnetic field lines and the particle orbits significantly differ both in strength and radial location in a toroidal configuration, except for the case of very low-energy particles whose orbits closely follow the magnetic field lines. The chaoticity of more energetic particles, undergoing large drifts with respect to the magnetic field lines, crucially determines the confinement properties of a toroidal device but cannot be inferred from that of the underlying magnetic field. In this work, we implement the Smaller ALignment Index (SALI) method for detecting and quantifying chaos, allowing for a systematic comparison between magnetic and kinetic chaos. The efficient quantification of chaos enables the assignment of a value characterizing the chaoticity of each orbit in the space of the three constants of the motion, namely energy, magnetic moment and toroidal momentum. The respective diagrams provide a unique overview of the different effects of a specific set of perturbations on the entire range of trapped and passing particles, as well as the radial location of the chaotic regions, offering a valuable tool for the study of particle energy and momentum transport and confinement properties of a toroidal fusion device.Comment: 27 pages, 7 figure

Role of the edge electric field in the resonant mode-particle interactions and the formation of transport barriers in toroidal plasmas

The impact of an edge radial electric field on the particle orbits and the orbital spectrum in an axisymmetric toroidal magnetic equilibrium is investigated using a guiding center canonical formalism. Poloidal and bounce/transit-averaged toroidal precession frequencies are calculated, highlighting the role of the radial electric field. The radial electric field is shown to drastically modify the resonance conditions between particles with certain kinetic characteristics and specific perturbative non-axisymmetric modes and to enable the formation of transport barriers. The locations of the resonances and the transport barriers, that determine the particle, energy and momentum transport are shown to be accurately pinpointed in the phase space, by employing the calculated orbital frequencies.Comment: 23 pages, 8 figure

Intelligent Data Analytics from the Energy Economics of the Greek Debt Crisis

Intelligent tools are brought to bear on the analysis of energy data from Greece in the period 2010-20. During this period a paradoxical phenomenon is observed namely, an increase in energy productivity in the midst of unprecedented economic decline as measured by Gross Domestic Product (GDP). Preliminary results identify improvements in the overall efficiency of capital due to the collapse in demand following draconian austerity measures. Background, directions and trends are analyzed, policy alternatives examined, and, a new measure of energy utilization with possible real-time applications is proposed. © 2020 IEEE
