  1. 11. Friction and Wear Mechanisms of Ceramic Surfaces With Applications to Micro Motors and Hip Joint Replacements

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johanna Olofsson; Uppsala universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. READ MORE

  2. 12. On interface modeling  with emphasis on friction

    University dissertation from Stockholm : KTH

    Author : Anders Söderberg; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface model; contact; friction; simulation; system behaviour; surface roughness; elastic foundation; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Abstract : The general trend toward increased use of computer models and simulations during product development has led to a need for accurate and reliable product models. The function of many products relies on contact interfaces between interacting components. READ MORE

  3. 13. Flow and Friction On the Tactical Potential of Interfacing with Glitch Art

    University dissertation from Stockholm : Department of Culture and Aesthetics, Stockholm University

    Author : Vendela Grundell; Stockholms universitet.; [2016]
    Keywords : HUMANIORA; HUMANITIES; Glitch; Contemporary Art; Photography; Digital Media; Interface; Internet; Systems Aesthetics; Network Society; Tactics; Phenomenology; Spectatorship; Viewer; Experience; Rosa Menkman; Phillip Stearns; Evan Meaney; konstvetenskap; Art History;

    Abstract : This thesis aims to analyze how interfacing affects viewer experiences and viewer positions, and how glitch art online makes that effect visible. Glitch art is concerned with disruptions in the systems that govern how for instance photography is produced, circulated and displayed in a digital image flow. READ MORE

  4. 14. Studies of Nanowire Friction using AFM-based Manipulation

    University dissertation from Department of Physics, Lund University

    Author : Gabriela Conache; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomanipulation; AFM; Nanowires; Nanotribology; Friction; Nanotechnology.;

    Abstract : In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length.

  5. 15. Friction and wear in rolling and sliding contacts

    University dissertation from Stockholm : KTH

    Author : Christer Spiegelberg; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; friction; wear; rolling and sliding contacts; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Abstract : Mechanical products are always expected to perform better, last longer, be more environmentally friendly and preferably cost less. Rolling and sliding contacts are found in many mechanical products, and friction and wear in the contacts have a direct impact on the products’ ability to meet these demands. READ MORE
