  2. 1. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation

    Author : Roger Enblom; KTH; []
    Keywords : contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. READ MORE

  5. 3. The Affective Profile Model: ill-being and well-being

    Author : Erica Schütz; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; affective profile; affect; ill-being; well-being; character;

    Abstract : Positive and negative affect have emerged as significant independent dimensions in studies of affective structure. Seeing affect as composed of two systems that can be categorized in high and low enables the possibility of four different combinations (i.e. READ MORE

  6. 4. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Author : Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Abstract : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. READ MORE

  7. 5. Low profile antennas for UWB

    Author : Magnus Karlsson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The number of wireless communication applications increases steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communication in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications.
