  1. 1. !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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

    Författare :Katarina Arbin; Sweden Stockholm Stockholm School of Economics; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; 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. 3. Electronic materials : growth and characterisation

    Författare :Michael A. Grishin; Ulf O. Karlsson; Massimo Sancrotti; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

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

    Författare :Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Embedded internet system architectures

    Författare :Åke Östmark; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inbyggda system; Embedded System;

    Sammanfattning : Today, using computers is a daily thing for many people over the world. We use computers to for example communicate, read news, search for sport events, correspond with e-mail, participate in meetings, and download the latest polyphonic ring tones for our mobile phones. LÄS MER
