    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbocyclization; Palladium Catalysis; Oxidation; Cyclization; Enallenes; Aza-Enallenes; Dienallenes; Allenylation; Oxazolidinones; Biomimetic; Arylation; Borylation; Transmetallation; organisk kemi; Organic Chemistry;

    Sammanfattning : The main focus of this thesis has been directed towards preparation and oxidative carbocyclization of en-, dien- and aza-enallenes.In the first part of this thesis, a stereoselective oxidative carbocyclization of dienallenes was realized. LÄS MER

  4. 18. Cooperative and non-cooperative wireless access : Resource and infrastructure sharing regimes

    Författare :Johan Hultell; Jens Zander; Cristina Comaniciu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radio resource managment competition cooperation game theory; Telecommunication; Telekommunikation;

    Sammanfattning : Future wireless networks will combine multiple radio technologies and subsystems, possibly managed by competing network providers. For such systems it may be advantageous to let the end nodes (terminals) make some or all of the resource management decisions. LÄS MER

    Sammanfattning : By 2020 there will be 50 billion connected devices over the Internet. With the fast-increasing data traffic demand in both fixed and mobile networks, network operators need to migrate networks towards next generation solutions. LÄS MER

  7. 20. Hybrid Routing in Next Generation IP Networks : QoS Routing Mechanisms and Network Control Strategies

    Författare :Antoine B Bagula; Björn Pehrson; Bukhard Stiller; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teletraffic systems; Teletrafiksystem;

    Sammanfattning : Communication networks have evolved from circuit-switched and hop-by-hop routed systems into hybrid data/optical networks using the Internet as a common backbone carrying narrow- and broad-band traffic offered by a multitude of access networks. This data/optical backbone is built around a multi-technology/multi-protocol routing architecture which runs the IP protocols in a collapsed IP stack where ATM and SONET/SDH have been replaced by the suite of Generalized Multiprotocol Label Switching (GMPLS) protocols.
