  1. 1. Time dependent material properties of shotcrete for hard rock tunnelling

    Författare :Lars Elof Bryne; Anders Ansell; Wolfgang Kusterle; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; rock; granite; bond strength; compressive strength; pullout testing; failure modes; interfacial transition zone; micro structure; ettringite; set accelerator; shrinkage; drains; glass fibres; laboratory testing; tunnels tunnelling;

    Sammanfattning : In this thesis different mechanical properties for shotcrete (sprayed concrete) such as compression strength, bond strength, bending tensile strength, elastic modulus, free and restrained shrinkage as a function of its age was investigated. One of the main issues was to investigate the difference between ordinary cast concrete and shotcrete. LÄS MER

  3. 2. A Programmable Network Interface Accelerator

    Författare :Ulf Nordqvist; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The bandwidth and number of users in computer networks are rapidly growing today. The need for added functionality in the network nodes is also increasing. The requirements on the processing devices get harder and harder to meet using traditional hardware architectures. LÄS MER

  4. 3. Transmutation of Am in sodium fast reactors and accelerator driven systems

    Författare :Youpeng Zhang; Janne Wallenius; Gérald Rimpault; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sodium cooled fast reactor; accelerator driven system; americium; transmutation; transient analysis;

    Sammanfattning : In this thesis, the feasibility to use sodium cooled fast reactors loaded with MOX, metallic and nitride fuels for efficient transmutation of americium is investigated by performing transient analysis for cases with different americium contents in fuels, using safety parameters obtained with the SERPENT Monte Carlo code. It was then demonstrated that there is no solid limit for the Am introduction into oxide, metallic and nitride fuels that were loaded into sodium fast reactors. LÄS MER

  5. 4. Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    Författare :Anna Shcherbakova; Sara Strandberg; Chad Finley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; b-tagging; calibration; Dark Matter; simplified model; Physics; fysik; High Energy Physics;

    Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. LÄS MER

  7. 5. Machine Learning in High-Energy Physics: Displaced Event Detection and Developments in ROOT/TMVA

    Författare :Kim Albertsson; Fredrik Sandin; Andreas Hocker; Tobias Golling; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyber-Physical Systems; Cyberfysiska system;

    Sammanfattning : Many proposed extensions to the Standard Model of particle physics predict long-lived particles, which can decay at a significant distance from the primary interaction point. Such events produce displaced vertices with distinct detector signatures when compared to standard model processes. LÄS MER
