  1. 11. "near friendly or neutral shores" : the deployment of the fleet ballistic missile submarines and US policy towrads Scandinavia, 1957-1963

    Författare :Nils Bruzelius; Hans Weinberger; Kjell Engelbrekt; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; History of technology; Teknikhistoria;

    Sammanfattning : The Polaris submarine, USS George Washington, went on her first deterrent patrol in November 1960. By that, the US Navy had acquired the capability to deliver a retaliatory attack upon Moscow and other cities in the Soviet Union by means of submarine launched ballistic missiles. LÄS MER

  3. 12. Reliability versus Cost in Next Generation Optical Access Networks

    Författare :Mozhgan Mahloo; Lena Wosinska; Jiaji Chen; David B Payne; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber access network; passive optical network; reliability; techno-economic study; next generation optical access; network protection; wavelength division multiplexing;

    Sammanfattning : The ever increasing demands of Internet users caused by the introduction of new high bandwidth applications and online services as well as the growing number of users and devices connected to the Internet, bring many challenges for the operators, especially in the last mile section of the network. Next generation access architectures are expected to offer high sustainable bandwidth per user. LÄS MER

  4. 13. Studies on the Viability of Cellular Multihop Networks with Fixed Relays

    Författare :Bogdan Timus; Jens Zander; Halim Yanikomeroglu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : The use of low cost fixed wireless relays has been proposed as a way to deploy high data-rate networks at an affordable cost. During the last decade, significant academic and industrial research has been dedicated to relays. Protocol architectures for cellular-relaying networks are currently considered for standardization as part of both IEEE 802. LÄS MER

  5. 14. Design, analysis and simultion for optical access and wide-area networks

    Författare :Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

    Sammanfattning : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. LÄS MER

  7. 15. Modelling and Simulating Demand-Responsive Transport

    Författare :Sergei Dytckov; Jan A. Persson; Paul Davidsson; Erik Jenelius; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Demand Mobility; Demand Responsive Transport; Modelling and Simulation; Sustainability;

    Sammanfattning : Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. LÄS MER
