    Sammanfattning : We are increasingly dependent on Internet as a large aspect of our daily life is now handled via online applications. Recent years we have seen several large-scale crises. This has made crisis-related research on Internet applications important. LÄS MER

  3. 2. On Overload Control and Performance Agreements in a Parlay/OSA Environment

    Författare :Jens K Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems; numerical analysis; Computer science; Parlay OSA; Overload Control; Performance Agreements; control; Datalogi; numerisk analys; system; kontroll; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : Parlay/OSA is a service architecture for current and next generation telecommunication networks. A gateway provides the applications with abstracted network functionality via Application Programming Interfaces. This facilitates the creation of telecommunication services and applications from independent software developers. LÄS MER

  4. 3. Optimal Railroad Power Supply System Operation and Design : Detailed system studies, and aggregated investment models

    Författare :Lars Abrahamsson; Lennart Söder; Arnd Stephan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.

  5. 4. Overload control strategies for distributed communication networks

    Författare :Maria Kihl; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource allocation; simulation models; TINA; Intelligent Networks; distributed systems; performance analysis; overload control; Telecommunication engineering; Telekommunikationsteknik;

    Sammanfattning : In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. LÄS MER

  7. 5. Multiple Aspects of Dynamic Rating in the Power System

    Författare :Seyede Fatemeh Hajeforosh; Math Bollen; Sarah Rönnberg; Alfredo Vaccaro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic rating; Transmission lines; Overload Protection; Stochastic analysis; Hosting capacity; Transformers; Electric Power Engineering; Elkraftteknik;

    Sammanfattning : Increased consumption and increased use of renewable energy make overhead lines and transformers more often congested. Dynamic rating (DR) uses a time-depending maximum permissible current instead of a long-term-fixed rating; it is an effective solution to upgrade the capacity of existing grid assets to minimize this congestion.
