    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  5. 3. Meson production in pd collisions

    Author : Karin Schönning; Jozef Zlomanczuk; Bo Höistad; Susan Schadmand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; meson production; measured angular distribution; total cross section; polarisation; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

    Abstract : Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. READ MORE

  6. 4. Coupled vibrations in horizontal and vertical rotor-bearings systems

    Author : Jean-Claude Luneno; Magnus Karlberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology - Engineering mechanics; Teknikvetenskap - Teknisk mekanik; Hållfasthetslära; Solid Mechanics;

    Abstract : For dynamical systems having several degrees of freedom, motion in one direction can induce motion in the other and/or vice versa. This means that there is a certain coupling between these two motions. Coupling can in some cases be a source of instability that causes self-excited vibrations in rotating machinery. READ MORE

  7. 5. Plastic Deformation of Duplex Stainless Steel

    Author : Magnus Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Abstract : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. READ MORE
