  2. 1. Perceive those things which cannot be seen : A cognitive systems engineering perspective on requirements management

    Author : Åsa Hedenskog; Rune Gustavsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software tools; Usability requirements; Cognitive systems engineering; Systems engineering; Systemteknik;

    Abstract : Non-functional requirements contribute to the overall quality of software, and should therefore be a part of any development effort. However, in practice they are often considered to be too difficult to handle. The purpose of this thesis is to gain understanding of where the nature and origin of these difficulties may lie.

  4. 2. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Author : Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Keywords : Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  5. 3. Making the Dead Alive : Dynamic Routines in Risk Management

    Author : Martin Lundgren; Åsa Ericson; Johan Holmqvist; Stewart James Kowalski; Luleå tekniska universitet; []
    Keywords : 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 ;

    Abstract : 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.

  6. 4. Modelling and controlling of polymer electrolyte fuel cell systems

    Author : Yuanxin Qi; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis focuses on the modelling and controlling of polymer electrolyte fuelcell (PEFC) systems. A system level dynamic PEFC model has been developedto test the system performance (output voltage, reactants gas partial pressures,and stack temperature) for different operating conditions.
