  1. 1. Information Systems Actability : Understanding Information Technology as a Tool for Business Action and Communication

    Författare :Pär J. Ågerfalk; Göran Goldkuhl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; information systems; information systems actability; Internet-based information systems; language action perspective; Information technology; Informationsteknologi;

    Sammanfattning : This dissertation is devoted to a perspective from which IT-based information systems are conceived as information technological artefacts intended for business action and communication. The perspective has been made concrete through the concept of information systems actability, which is the main concept under scrutiny. LÄS MER

  3. 2. Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage

    Författare :Närman Per; Mathias Ekstedt; Pontus Johnson; Sjaak Brinkkemper; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Metamodeling; Decision-making; Data Accuracy; Service Availability; Service Performance; Technology Acceptance Model; Task Technology Fit;

    Sammanfattning : Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. LÄS MER

    Sammanfattning : Spin-torque and spin Hall nano-oscillators are nanoscale devices (about 100 nm) capable of producing tunable broadband high-frequency microwave signals ranging from 0.1 GHz to over 65 GHz that several research groups trying to reach up to 200 - 300 GHz. LÄS MER

  5. 4. On the interaction between driver assistance systems and drivers in situations of system failure

    Författare :Josef Nilsson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive cruise control; Chalmers driving simulator; automotive safety; controllability; driver assistance systems; functional safety; dependability; brake failure; fault injection;

    Sammanfattning : The level of automation is increasing in road vehicles as driver assistance systems take control of both speed and steering. Benefits of this development are expected in the form of improved safety, driver comfort, traffic efficiency, etc. LÄS MER

  7. 5. Improving Software Quality through Understanding and Early Estimations

    Författare :Anders Wesslén; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Personal Software Process; process improvement; software development process; defects; faults; failures; test planning; early estimations; usage profile; usage model; statistical usage testing; Software quality; software reliability; Systems engineering; computer technology; Data- och systemvetenskap;

    Sammanfattning : Software quality is an important factor of a large and complex software system. Hence, there is a need for measuring and controlling quality. Software quality has, however, many different f actors and involves implicit expectations of the behaviour of the software. LÄS MER
