    Sammanfattning : The current global restructuring processes are usually described in terms of increased integration and, concurrently, greater fragmentation among different regions and scales. How these parallel outcomes are reflected in the civic sphere, largely for those mostly affected, i.e. the urban grassroots, is the focus of this study. LÄS MER

  3. 2. From data collection to electric grid performance : How can data analytics support asset management decisions for an efficient transition toward smart grids?

    Sammanfattning : In 2002, Sweden finally stopped producing air raid shelters for its population after over sixty years of continuous production since 1938. Judging from the Swedish Civil Contingencies Agency, MSB, the Swedish Air raid shelter registry contain about 65,000 air raid shelters registered as being in use. LÄS MER

  7. 5. Structural integrity of prestressed nuclear reactor containments

    Författare :Patrick Anderson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel liner; reliability; relaxation; shrinkage; creep; loss of prestress; tendon; Nuclear; containment; design pressure; Construction technology; Anläggningsteknik;

    Sammanfattning : A nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. LÄS MER
