    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

    Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

  7. 10. Design, Development, and Adoption of Ontology-Driven Clinical Software

    Författare :Marie Gustafsson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknologi; Teknik; Technology; online communities;

    Sammanfattning : This thesis addresses how ontology-driven applications can be designed and developed to support distributed clinical knowledge management in oral medicine, where geographically dispersed practitioners need to share practical clinical knowledge. A step in developing tools for knowledge management is representing knowledge in a machine-processable and sharable manner. LÄS MER
