  1. 1. The development of wireless infrastructure standards

    Författare :Fredrik Gessler; KTH; []
    Nyckelord :standards; standardisation; wireless communication; technologocial development; development process; DECT; WCDMA; 3G;

    Sammanfattning : This thesis treats the development of wirelessinfrastructure standards resulting from co-operative research,development and standardisation efforts. It strives to identifykey influences on this development process, and toconceptualise the process itself. LÄS MER

  3. 2. Government's Role for Transport Infrastructure : Theoretical Approaches and Historical Development

    Författare :Björn Hasselgren; Göran Cars; Hans Lind; Mark Pennington; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Government; Market; Planning; Transport Infrastructure;

    Sammanfattning : This thesis analyzes and discusses the development of the Swedish government’s role as owner and financier of roads and railroads from the 1930s until the 2010s. The influence on the development of the government’s role from two main theoretical paradigms is discussed and analyzed. LÄS MER

    Sammanfattning : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. LÄS MER

  5. 4. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

    Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

    Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

  7. 5. Evaluation of concrete structures : strength development and fatigue capacity

    Författare :Håkan Thun; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : This licentiate thesis consists of four papers. In paper A the development of tensile and compression strength are presented for old concrete railway trough bridges. The compression strength has usually increased 50 to 100% over the years. However the same could not be said for the tensile strength. LÄS MER
