  2. 1. Fatigue of steel bridges : New structural details and the implementation of high strength steel

    Author : Oskar Skoglund; John Leander; Raid Karoumi; Alain Nussbaumer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high strength steel; fatigue; steel bridges; steel and concrete composite bridges; new structural details; linear elastic fracture mechanics; effective notch stress method; nominal stress method; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. READ MORE

  4. 2. A study of slag-steel-inclusion interaction during Ladle treatment

    Author : Johan Björklund; Pär Jönsson; Voicu Brabie; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; steel; slag; inclusions; ladle; refining; vacuum; tool steel; oxide activity; slag models; oxygen; equilibrium; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. READ MORE

  7. 5. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression

    Author : Ali Tofigh; Jens Lagergren; Mike Steel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lateral Gene Tranfer; Horizontal Gene Transfer; Cancer Progression; Bioinformatics; Bioinformatik; Computer science; Datalogi;

    Abstract : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.
