    Sammanfattning : Achieving product and process quality are among the central themes of software engineering, and quality is an important factor in the marketplace. Usability and user experience (UX) are two important aspects of quality, particularly for interactive products. LÄS MER

  4. 4. A Conceptual Model for Analysis of Automation Usability Problems in Control Room Settings

    Författare :Jonas Andersson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Human-machine systems; control rooms; cognitive systems engineering; nuclear power; levels of automation; usability problems;

    Sammanfattning : The focus of this licentiate thesis lies on the problems that can emerge when humans and advanced control systems work together in control room environments. In the nuclear domain, automation is used extensively and it is important to maintain safe and efficient operations. LÄS MER

  5. 5. Usability of Firewall Configuration : Making the Life of System Administrators Easier

    Författare :Artem Voronkov; Stefan Lindskog; Leonardo Martucci; John Sören Pettersson; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; network security; usable security; firewall configuration; firewall interfaces; usability metrics; Computer Science; Datavetenskap;

    Sammanfattning : Firewalls are an important component of network security that serve to protect networks by regulating incoming and outgoing traffic. However, setting up firewalls correctly is a challenging task, which becomes more difficult with the growth of the network's size. LÄS MER
