  2. 11. Building Energy Efficiency - Policy, learning and technology change

    Author : Bernadett Kiss; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Policy learning; technology change; energy efficiency; building;

    Abstract : Experience shows that energy efficiency improvements are the most cost-effective path to meeting global energy challenges. To promote energy efficiency, various policy instruments have been in place since the 1970s. READ MORE

  4. 12. On distributed coding for relay channels

    Author : Zhongwei Si; Mikael Skoglund; Ragnar Thobaben; Alexandre Graell i Amat; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : Cooperative transmission is considered to be a key-technique for increasing the robustness, the efficiency, or the coverage of wireless communication networks. The basic concept is that the information transmission from a sender to a receiver can be aided by one or several relay nodes in a cooperative manner under constraints on power, complexity or delay.

  5. 13. Coding for the Wiretap Channel

    Author : Mattias Andersson; Mikael Skoglund; Michael Lentmaier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : We consider code design for Wyner’s wiretap channel. Optimal coding schemes for this channel require an overall code that is capacity achieving for the main channel, partitioned into smaller subcodes, all of which are capacity achieving for the wiretapper’s channel. READ MORE

  6. 14. Studies of Gas Disks in Binary Systems

    Author : Miguel de Val Borro; Pawel Artymowicz; William Benz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : There are over 300 exoplanets detected through radial velocity surveys and photometric studies showing a tremendous variety of masses, compositions and orbital parameters. Understanding the way these planets formed and evolved within the circumstellar disks they were initially embedded in is a crucial issue. READ MORE

  7. 15. Novel Diagnostics and Computational Methods of Neutron Fluxes in Boiling Water Reactors

    Author : John Loberg; Michael Österlund; Thomas Smed; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Void; BWR; neutron fluxes; channel bow; MCNP; 2D 3D; Physics; Fysik;

    Abstract : The focus in this thesis is to improve knowledge of the BWR related uncertainties void, channel bow, and control rods. The presence of void determines the moderation of neutrons in BWRs. A high void fraction is less efficient in moderating neutrons than a low one. READ MORE
