  1. 1. Performance determinants and classification in paracanoe

    Author : Johanna Rosén; Anna Bjerkefors; Anton Arndt; Vicky Tolfrey; Carl Payton; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; canoe; outrigger; para sport; disability; impairment; Paralympics; kinematics; kinetics; Medicin Teknik; Medicine Technology;

    Abstract : Valid classification systems are vital for Paralympic sports in order to minimise the impact of impairment on sports performance. To achieve valid classification, each Paralympic sport must develop evidence-based classification systems by examining the impact of impairment on key performance determinants. READ MORE

  2. 2. Characterization of metal plasma streams from arc discharges in a reactive environment

    Author : Johanna Rosén; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Alumina is a material used in many applications mainly due to its chemical inertness and wear resistance at high temperatures. Despite this, the understanding of alumina thin films is not satisfactory, as can be concluded from the diverging material properties reported in the literature. READ MORE

  3. 3. Multifunctional Transition-metal Diboride Coatings Synthesized by Magnetron sputtering with Synchronized Metal-ion Irradiation

    Author : Babak Bakhit; Grzegorz Greczynski; Johanna Rosén; Paul Mayrhofer; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY;

    Abstract : Refractory transition-metal diborides (TMB2), classified as ultra-high temperature ceramics, are promising materials for extreme thermal and chemical environments. There is a growing demand for employing TMB2 in high-temperature electrodes, advanced nuclear fission reactors, molten metal containment, refractory crucibles, thermocouple protection tubes in steel baths and aluminum reduction cells, reinforcement fibers, solar power, aerospace, and armor applications.

  4. 4. Computational prediction of novel MAB phases

    Author : Adam Carlsson; Johanna Rosén; Denis Music; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The synthesis procedure of any materials system is often considered a challenging task if performed without any prior knowledge. Theoretical models may thus be used as an external input and guide experimental efforts toward novel exotic materials which are most likely to be synthesizable. READ MORE

  5. 5. Materials Design from First Principles : stability and magnetism of nanolaminates

    Author : Martin Dahlqvist; Johanna Rosén; Nicola Spaldin; Linköpings universitet; []
    Keywords : ;

    Abstract : In this thesis, first-principles calculations within density functional theory are presented, with a principal goal to investigate the phase stability of so called Mn+1AXn (MAX) phases. MAX phases are a group of nanolaminated materials comprised of a transition metal (M), a group 12-16 element (A), and carbon or nitrogen (X). READ MORE
