  1. 1. Individual information system acceptance behaviour : An electronic ordering system case

    Författare :Katarina Arbin; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; information system; e-procurement; e-ordering; individual; acceptance; adoption; continued use; behaviour; structures; routines; longitudinal; case study;

    Sammanfattning : Organizations have spent and continue to spend millions of dollars on information systems (IS) in order to enable business success. Information systems have long been used to help managers make better decisions, better understand the nature of customers and improve employee productivity. LÄS MER

  3. 2. !secure(system) <=?=> !safe(system) : On Security and Safety of Industrial Software Systems

    Författare :Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; hard real-time; concurrency; model of computation; safety-critical; safety; security; industrial automation; RTFM; real-time for the masses; Embedded Systems; Inbyggda system;

    Sammanfattning : The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. LÄS MER

  4. 3. Electronic materials : growth and characterisation

    Författare :Michael A. Grishin; Ulf O. Karlsson; Massimo Sancrotti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Photoemission; Ultra-short laser pulse; Thin film; Laser deposition; InSb; InAs; GaSb; Ferroelectrics; Elektrofysik; Electrophysics; Elektrofysik;

    Sammanfattning : In this thesis the InSb(111), InAs(111) and GaSb(001) surfaces have been studied by means of time- and angle-resolved photoemission spectroscopy based upon the femtosecond laser system. The pump-and-probe technique allows to analyse both electron states in the valence band and normally unpopulated electron states above the valence band, which can be occupied by transiently excited carriers at the optically pumped surface.

  5. 4. Identifying critical components for system reliability in power transmission systems

    Författare :Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission system reliability; component reliability importance index; Great Britain power system; power flow analysis; system adequacy; system security; system vulnerability;

    Sammanfattning : Large interruptions of power supply in the transmission system have considerable impact on modern society. The goal for the transmission system operator (TSO) is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. LÄS MER

  7. 5. Elektroniska marknadsplatser : IT-stöd för små och medelstora leverantörer

    Författare :Johan Petersson; Göran Goldkuhl; Karin Axelsson; Fredrik Karlsson; Martin Henkel; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Electronic marketplaces; Information systems; Small and medium -sized enterprises; Practice theory; Elektroniska marknadsplatser; informationssystem; små och medelstora företag; praktikteori;

    Sammanfattning : Den här avhandlingens ämne är elektroniska marknadsplatser och hur sådana bör utformas utifrån mindre leverantörers perspektiv. Med leverantörer avses här de säljande företag som använder marknadsplatser som mellanhand för att sälja varor och tjänster. LÄS MER
