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

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola, Institutionen för byggnadsfysik

    Författare :Karin Margaretha Borgström; Högskolan i Halmstad.; [1994]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Sammanfattning : 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. The Development of Swedish Business Journalism Historical Roots of an Organisational Field

    Detta är en avhandling från Uppsala : Företagsekonomiska institutionen

    Författare :Maria Grafström; Uppsala universitet.; [2006]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; institutional theory; organisational field; field emergence; institutional entrepreneurs; business journalism; business news; newspapers; Företagsekonomi;

    Sammanfattning : Contemporary Swedish business journalism is an established organisational field with shared practice within and across organisations. Using a historical perspective, this dissertation investigates the early formation of this field and the formation of a shared meaning system for business journalism. LÄS MER

  3. 3. Accounting in the field of governance

    Detta är en avhandling från Stockholm : School of Business, Stockholm University

    Författare :Sabina Du Rietz; Stockholms universitet.; [2013]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Administration; företagsekonomi; accounting; corporate; governance; field; investors; trade unions; accountability; technology;

    Sammanfattning : Corporate governance phenomena have traditionally been, and are still, studied foremost as relationships between principals and agents. Studies of how accounting plays out in corporate governance settings rather share the interest in hierarchical influence than challenge it. LÄS MER

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

    Detta är en avhandling från Stockholm : School of Business, Stockholm University

    Författare :Aidin Razavi; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimal near-field aperture; near-field focusing; near-field antennas; near-field power transfer; array signal processing.; maximum penetration;

    Sammanfattning : Antennas are traditionally designed for far-field applications such as wireless communications, radar, etc., where the antenna systems interact with other systems and objects which are located in the far-field zone of the antennas. LÄS MER

  5. 5. Moisture Influence on Structural Behaviour of Pavements Field and Laboratory Investigations

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Farhad Salour; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Falling Weight Deflectometer FWD ; backcalculation; unbound material; subgrade; seasonal variation; moisture content; spring-thaw; drainage; pavement stiffness; field test; pavement instrumentation; resilient modulus; permanent deformation; repeated load triaxial test; unsaturated soil; matric suction.; Civil and Architectural Engineering; Byggvetenskap; Transportvetenskap; Transport Science;

    Sammanfattning : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. LÄS MER
