    Sammanfattning : International petrol companies established themselves in Sweden in the mid-1920s and took control of the petrol trade in a manner that, within a relatively short space of time, left a clear imprint on the natural and built environments. The absence of petrol stations from the narrative of modern architecture raises questions about how this type of building should be understood. LÄS MER

    Sammanfattning : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. LÄS MER

  4. 3. Thermal response test : in situ measurements of thermal properties in hard rock

    Författare :Signhild Gehlin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : In-situ determination of thermal properties in bedrock is important for the sizing of larger BTES systems. In-situ values of thermal conductivity may reduce required borehole length up to 30%. This thesis treats a new mobile thermal response test equipment (TED), developed in Luleå, Sweden, 1995-98.
