  1. 1. First determination of the electric charge of the top quark

    University dissertation from Stockholm : KTH

    Author : Per Hansson; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : In this thesis, the first determination of the electric charge of the top quark is presented using 370pb-1 of data recorded by the DØ detector at the Fermilab Tevatron accelerator. ttbar events are selected with one isolated electron or muon and at least four jets out of which two are b-tagged by reconstruction of a secondary decay vertex (SVT).

  2. 2. Numerical Modelling of Short Fatigue Crack Growth

    University dissertation from Stockholm : KTH

    Author : Per Hansson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete dislocation; Fatigue; grain boundary; short crack;

    Abstract : Fatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. READ MORE

  5. 5. Control of weldability Research leading to the development of two new quenched and tempered tool steels

    University dissertation from Stockholm : Industriell produktion

    Author : Per Hansson; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : The understanding of the hardenability is important in steel development with respect to weldability of steels as well as to the design of quenched and tempered steels.The common way to judge if steel is suitability to welding is the use of a carbon equivalent, which reflects the alloy content to the hardenability of the heat affected zone (HAZ).
