  1. 1. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements

    University dissertation from Göteborg : Chalmers tekniska högskola, Institutionen för byggnadsfysik

    Author : Karin Margaretha Borgström; Margaretha Borgström; Högskolan i Halmstad.; Chalmers tekniska högskola.; Chalmers University of Technology.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture;

    Abstract : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains.The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.

  2. 2. Measurement systems and process orientation with focus on the order process

    University dissertation from Department of Engineering Logistics, Box 118, 221 00 Lund, Sweden

    Author : Anders Ljungberg; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process measurement; measurement systems; process management; measurement; Technological sciences; Teknik;

    Abstract : The inability of organisations to develop successfully and their lack of a holistic view and of relevant quantitative facts are factors that played a major role in my choice of a research area for this and my licentiate thesis (Ljungberg, 1994). These two theses together represent the work conducted for the PhD degree. READ MORE

  3. 3. Optimal Near-field Antenna Apertures in Lossy Media

    University dissertation from Chalmers University of Technology
