  1. 6. Discovering Information Security Management

    Författare :Fredrik Björck; Louise Yngström; Richard Baskerville; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Security; Information Systems Security; Management; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : This thesis is concerned with issues relating to the management of information security in organisations, motivated by the need for cost-efficient information security.It is based on the assumption that: in order to achieve cost-efficient information security, the point of departure must be knowledge about the empirical reality in which the management of information security takes place.

    Sammanfattning : The integration of information technology (IT) into service delivery is currently seen as an innovative strategy to support the modernising of universities worldwide. However, in some institutions in developing countries, including Rwanda, IT has failed to add the intended value to university services, despite huge associated investments in IT. LÄS MER

  4. 8. An Integrated Approach towards Model-Based Mechatronic Design

    Författare :Ahsan Qamar; Jan Wikander; Hans Vangheluwe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; Industrial engineering and economy; Industriell teknik och ekonomi; Software engineering; Programvaruteknik; Systems engineering; Systemteknik;

    Sammanfattning : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. LÄS MER

  5. 9. Utilizing Diversity and Performance Measures for Ensemble Creation

    Författare :Tuve Löfström; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; Computer science; Datavetenskap; Teknik; Technology;

    Sammanfattning : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. LÄS MER

  7. 10. Making the Dead Alive : Dynamic Routines in Risk Management

    Författare :Martin Lundgren; Åsa Ericson; Johan Holmqvist; Stewart James Kowalski; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Risk management; information security; routine; practice; asset identification; risk analysis; risk treatment; organizational aspects; Information systems; Informationssystem; Centrumbildning - Centrum för säkerhet i samhälle och kritiska infrastrukturer CISS ; Centre - Centre for Critical Infrastructure and Societal Security CISS ;

    Sammanfattning : Risk management in information security is relevant to most, if not all, organizations. It is perhaps even more relevant considering the opportunities offered by the digitalization era, where reliably sharing, creating, and consuming information has become a competitive advantage, and information has become an asset of strategic concern.
