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

    University dissertation from Institutionen för datavetenskap

    Author : Åsa Hedenskog; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software tools; Usability requirements; Cognitive systems engineering; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik 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.

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

    University dissertation from Stockholm : KTH

    Author : Dimitra Sakellari; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  4. 4. Inter-temporal Privacy Metrics

    University dissertation from Karlstad : Karlstad University Press

    Author : Stefan Berthold; Karlstads universitet.; [2014]
