  1. 6. Geometry and foundations of quantum mechanics

    Författare :Kate Blanchfield; Ingemar Bengtsson; Anthony Sudberry; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : This thesis explores three notions in the foundations of quantum mechanics: mutually unbiased bases (MUBs), symmetric informationally-complete positive operator valued measures (SICs) and contextuality. MUBs and SICs are sets of vectors corresponding to special measurements in quantum mechanics, but there is no proof of their existence in all dimensions. LÄS MER

  3. 7. Numerical modelling of the rock fracture process under mechanical loading

    Författare :Hongyuan Liu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : The fracture of rock has been the subject of the extensive research in the mechanical fragmentation. With the rapid development of computing power, interactive computer graphics and topological data structure, numerical tool has become a good tool to gain some insights into the problem of rock fracture.

  4. 8. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact

    Författare :Roger Enblom; Mats Berg; Simon Iwnicki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; wear; wear prediction; wear model; wheel profile; rail; Vehicle engineering; Farkostteknik;

    Sammanfattning : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. LÄS MER
