Ηλεκτρονική χαρτογράφηση τηλεπικοινωνιακής υποδομής στην περιφέρεια Δυτικής Ελλάδας

Ηρακλέους, Χρίστος 02 February 2011 (has links)
Η παρούσα διπλωματική εργασία εκπονήθηκε στο τμήμα Ηλεκτρολόγων Μηχανικών και Τεχνολογίας Υπολογιστών του Πανεπιστημίου Πατρών και το θέμα της αφορά την ηλεκτρονική χαρτογράφηση τηλεπικοινωνιακής υποδομής στην περιφέρεια δυτικής Ελλάδας και συγκεκριμένα για το μητροπολιτικό δίκτυο οπτικών ινών της Πάτρας και τον αυτόματο υπολογισμό των αποστάσεων από σημεία του υπάρχον δικτύου προς μελλοντικά σημεία επέκτασης του δικτύου. Η διπλωματική εργασία χωρίζεται σε 2 ενότητες.Στην 1η ενότητα στο 1ο κεφάλαιο παρουσιάζονται τα συστήματα επικοινωνιών με οπτικές ίνες και αναφέρονται τα επιμέρους εξαρτήματα που τα αποτελούν.Στη συνεχεία στο 2ο κεφάλαιο γίνεται αναφορά σε θέματα εγκατάστασης οπτικών ινών μέχρι τούς τελικούς συνδρομητές. Γίνονται κατηγοριοποιήσεις ανάλογα με το βαθμό συμμετοχής της οπτικής ίνας στη διαμόρφωση του τοπικού βρόχου,των διαφορετικών τοπολογιών στα οπτικά δίκτυα πρόσβασης αλλά και της τεχνολογίας που θα χρησιμοποιηθεί .Τέλος στο 3ο κεφάλαιο γίνεται αναφορά στις τεχνικές υλοποίησης οπτικών δικτύων , παρουσιάζονται οι απαιτήσεις για τις οπτικές υποδομές και δίνονται οι αναγκαίοι ορισμοί. Στην 2η ενότητα στο 4ο κεφάλαιο παρουσιάζονται τα συστήματα γεωγραφικών πληροφοριών Σ.Γ.Π., γίνεται ιδιαίτερη αναφορά στο ArcGIS το οποίο είναι και το πρόγραμμα που χρησιμοποιείται για τη ηλεκτρονική χαρτογράφηση του δικτύου,όπως παρουσιάζεται στο 5ο κεφάλαιο Στο 6ο κεφάλαιο γίνεται η μαθηματική παρουσίαση του προβλήματος της εύρεση της συντομότερης διαδρομής και την χρήση του αλγορίθμου του Dijkstra για την επίλυση αυτού ,τέλος στο 7ο κεφάλαιο παρουσιάζεται η εφαρμογή του αλγορίθμου του Dijkstra στο περιβάλλον του ArcGIS για τον υπολογισμό της συντομότερης διαδρομής από ένα σημείο του δικτύου προς ένα άλλο σημείο του πιθανού μελλοντικού δικτύου. / This diploma thesis has been developed within the Department of Electrical and Computer Engineering, University of Patras and its issue is the electronic mapping of a telecommunications infrastructure in the region of western Greece and specifically for the metropolitan fiber optic network of Patras and the automatic calculation of distances from points of existing network to points for the future network expansion. The diploma thesis is divided in to two sections. In the first section, the 1st chapter presents the fiber-optic communications systems and their individual components. Then the 2nd chapter refers to fiber optic installation issues to final subscribers. Categorizations are made depending on the degree of involvement of fiber-optic in shaping the local loop, different topologies in optical access networks and the technology used. Finally the 3rd chapter refers to the technical implementation of optical networks, present the requirements for optical infrastructure and given the necessary definitions. In the second section the 4th chapter presents the geographic information systems GIS, special reference is made to ArcGIS which is the program used for the electronic mapping of the network, as presented in the 5th chapter. The 6th chapter is the presentation of the mathematical problem of finding the shortest route and the use of Dijkstra's algorithm for solving this problem. Finally the 7th chapter presents the implementation of Dijkstra's algorithm in the environment of ArcGIS for the calculation of the shortest route from one point of the network to another point of potential future network.

Durante essas décadas, o Brasil passa a vivenciar um contexto de crises econômicas e políticas sucessivas e superpostas que acabam por expôr a incapacidade do Estado desenvolvimentista em superá-las. Com a transição democrática, inicia-se um debate acerca da necessidade de reforma do Estado, intensificado a partir de 1987 com o fracasso do Plano Cruzado. Tal projeto de reforma é posto em movimento a partir do Governo Collor (1990-1992), mas somente atinge sua forma mais acabada e se consolida durante o governo do Presidente Fernando Henrique Cardoso (1995-2002). Considerando esse contexto, a proposta deste estudo é analisar, sob a perspectiva do desenvolvimento, o impacto da administração gerencial do Estado implementada durante esse período sobre o setor de infra-estrutura econômica (energia, telecomunicações, transportes), tendo em vista o fato de que este foi um setor historicamente promovido pela ação do Estado desenvolvimentista e, no período estudado, passa por um intenso processo de abertura, desregulamentação e privatizações / The 1980’s and 1990’s were marked by the intense discussion about the subject of redefinition of the State role in many ways. During these decades, Brazil started experiencing a context of successive and overlapping economic and political crises which ultimately exposed the inability of the developmentalist State to overcome them. As the democratic transition took place, a debate about the need of reform the State began, intensified after the failure of the Cruzado Plan in 1987. Such reform project was initiated by the Fernando Collor administration (1990-1992), but only reached its most finished and developed form in the Fernando Henrique Cardoso administration (1995-2002). Considering this context, this paper proposes to investigate, from the perspective of development, the origins of the managerial administration of the State and its effects over the infra-structure sector in Brazil, considering the fact that this sector was historically promoted by the developmentalist State and, at the period, went through an intense process of opening, deregulation and privatization

Pendelparkering vid Boterstena : Typfall 1

Ramanouskaya, Olga January 2018 (has links)
Vid busshållplatsen Boterstena längs väg 26 ska en pendelparkering byggas. Det ska ske genom frivillig markåtkomst. Pendelparkeringen ska anläggas i anslutning till väg 2593 in mot Tidavad samhälle och omfatta 10 platser med möjlighet att kunna utöka på ett enkelt sätt om större behov skulle uppstå i framtiden. En yta för cykelställ med tak ska iordningsställas där, Västtrafik ansvarar för cykelställ. Åtgärden omfattar även säkrare passage över väg 26 samt säkrare gångstråk från pendelparkering till och från hållplatserna.
