  1. 1. Vibro-impact dynamics of fretting wear

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jakob Knudsen; Malmö University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Technology;

    Sammanfattning : The dynamics and wear of non-linear impact oscillators, comprising a single-degree of freedom system as well as continuous beam systems are analysed. The considered beams are of cantilever type with the lateral motion of the free end constrained by elastic supports. They are modelled as Bernoulli beams with Rayleigh damping. LÄS MER

  3. 2. Automated subject classification of textual web pages, for browsing

    Detta är en avhandling från Digital Information Systems Group, Department of Information Technology, Lund University

    Författare :Koraljka Golub; Lunds universitet.; Lund University.; [2005]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Library and Information Science; Biblioteks- och informationsvetenskap; automated classification; subject browsing; structural Web-page elements; Web page classification; document clustering; bibliographic coupling; text categorization; Subject classification;

    Sammanfattning : With the exponential growth of the World Wide Web, automated subject classification of Web pages has become a major research issue in information and computer sciences. Organizing Web pages into a hierarchical structure for subject browsing is gaining more recognition as an important tool in information-seeking processes. LÄS MER

  4. 3. The Triumph of Technology Over Politics? Reconstructing Television Systems: The Example of Sweden

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Lena Ewertsson; Linköpings universitet.; Linköpings universitet.; Göteborgs universitet.; Gothenburg University.; [2001]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Interdisciplinary studies; Television broadcasting; cable television; satellite television; socio-technical systems; large technical systems; entrepreneurship; Industriförvaltnings AB Kinnevik; TV3; Sweden; Tvärvetenskap; Kabel-TV; Satellit-TV; Public service; Sverige; television; liberalisation; sociotechnical systems; innovation;

    Sammanfattning : Based upon perspectives and concepts from social and historical research on technical systems, this dissertation describes and analyses events and processes relating to the dramatic change in television in Western Europe during the 1980s and early 1990s. In particular, it focuses on how Swedish television, conceived as a large socio-tecnical system, has shifted from a traditional 'public service' system to a more open and mixed system. LÄS MER

    Sammanfattning : With the exponential growth of the World Wide Web, automated subject classification has become a major research issue. Organizing web pages into a hierarchical structure for subject browsing has been gaining more recognition as an important tool in information-seeking processes. LÄS MER

  7. 5. Development of high-Tc SQUID magnetometers for on-scalp MEG

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Minshu Xie; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanowire junctions; on-scalp MEG; Bicrystal grain boundary; magnetoencephalography; YBCO; magnetometers; high-Tc SQUIDs;

    Sammanfattning : This thesis describes the development of high critical temperature superconducting quantum interference device (high-Tc SQUID) magnetometers based on bicrystal grain boundary and nanowire junctions for the potential use in on-scalp magnetoencephalography (MEG), which is a new generation MEG technique with reduced sensor-to-subject standoff distances.MEG is a method of mapping neural dynamics in the human brain by recording the magnetic fields produced by neural currents.
