    Sammanfattning : Studies about the industrial standard IEC 61499 and its relation to the RTFM Model of Computation represent the basis of this thesis. An overview of industrial automation software in general and in the scope of Svenska Kraftnät introduces the subject of software related issues. LÄS MER

  3. 22. Diffusive properties of granitic rock as measured by in-situ electrical methods

    Författare :Martin Löfgren; Ivers Neretnieks; Peter Vilks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Diffusion into the rock matrix has been identified as one of the most important retention mechanisms for dissolved contaminants in fractured crystalline rock. In this thesis the diffusive properties of granitic rock, described by the formation factor, have been investigated by electrical methods. LÄS MER

  4. 23. Fluid migration and brittle tectonothermal evolution in the central Fennoscandian Shield - recorded by fracture minerals and wall rock alteration

    Författare :Björn Sandström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Forsmark area in central Sweden has been investigated as a potential geological host for a final repository of spent nuclear fuel by the Swedish Nuclear Fuel and Waste Management Company (SKB). High quality drill core material from the upper 1 km of the central Fennoscandian Shield has been obtained during the site investigations and has provided a unique opportunity for detailed fracture mineralogical investigations.

  5. 24. Maintenance management of complex industrial systems : a methodology for renewal strategies

    Författare :Mathias Wärja; Torsten Cegrell; Per Lamell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual lifetime estimation; maintennance management; technical systems in power and pulp- and paper industries; long terms maintenance strategies; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : For complex technical systems in the electricity and pulp and paper industries, maintenance management addresses how to exploit physical assets in the most profitably way. This is a difficult task that requires taking into consideration parameters of totally different natures – e.g. LÄS MER

  7. 25. Effects of warming on the ecology of algal-dominated phytobenthic communities in the Baltic Sea

    Författare :Filip Svensson; Pauline Snoeijs; Johan Eklöf; Hans Kautsky; Nils Ekelund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; warming; photosynthesis; trophic cascades; pigments; community traits; temperature gradient; invasive mussel; Marine Ecology; marin ekologi;

    Sammanfattning : Through climate change, the global average air and surface water temperature has risen 0.85°C during the last 100 years. The Baltic Sea experienced one of the most rapid increase in temperature recorded of marine ecosystems. LÄS MER
