  1. 21. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions

    Författare :Samira Mousavi Nik; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Grain Growth.; Interfaces; Microstructure; AlOx Tunnel Barriers; Transmission Electron Microscopy; Imaging; Spectroscopy; Superconducting Tunnel Junctions;

    Sammanfattning : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

  2. 22. "But can't you see they are lying" : student moral positions and ethical practices in the wake of technological change

    Detta är en avhandling från Göteborg : Acta Universitatis Gothoburgensis

    Författare :Lars-Erik Nilsson; Högskolan Kristianstad.; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Social sciences Education; SAMHÄLLSVETENSKAP Socialvetenskap Pedagogik; Technology in education; positioning; ethical practices; technology in education;

    Sammanfattning : Today it is considered important that modern digital technology be implemented and that all citizens learn to use it. Students already use mobile phones, personal digital assistants, computers, and their applications to do much of their work. This includes searching for and retrieving information, and collaborating on assignments and writing. LÄS MER

  5. 25. The pace of innovation : Patterns of innovation in the cardiac pacemaker industry

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Patrik Hidefjäll; Linköpings universitet.; Linköpings universitet.; [1997]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cardiac Pacemaker; Competition; Competitive Advantage; Defibrillator; Dominant Design; Innovation; Organizational Field; Patterns of Innovation; Technical Change; Technology Cycle; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The PhD thesis "The Pace of Innovation" addresses the questions how patterns of innovation change over time in an industry, their consequences for competition and how institutional conditions in an industry shape determinants of patterns of innovation. Patterns of innovation mainly refer to how certain regularities in the diversity, types and locus of innovation change in an industry according to a technology and industry life cycle. LÄS MER
