    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Niklas Ågren; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas turbine cycles; HAT cycles; evaporative cycles; power generation;

    Sammanfattning : Since the early 80's, the worldwide utilization of gas turbines for thermal power generation has increased rapidly. They have less pollution than any other major combustion energy converters. LÄS MER

  4. 4. Growth and Business Cycles : Swedish Manufacturing Industry 1952-2001

    Detta är en avhandling från Stockholm : Almqvist & Wiksell International

    Författare :Camilla Maria Kyllikki Josephson; Lennart Schön; Deirdre Nansen MC Closkey; [2005]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Contemporary history; Manufacturing industry; Knowledge accumulation; The cointegrated VAR model; Business cycles; Economic growth; TFP growth;

    Sammanfattning : This study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract the dampening effect of diminishing returns, we are still in the dark about how such mechanisms operate.

  5. 5. Evaluation of test cycles for freight locomotives

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

    Författare :Mattias Skoglund; Stefan Östlund; Peter Thelin; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duty cycles; test cycles; diesel locomotives; locomotive emissions; dual modes; hybrid systems;

    Sammanfattning : Diesel locomotives provide versatility to the railway system as they do not depend on electric feeding. Worldwide they constitute important parts of locomotive fleets used for various tasks such as mainline services, shunting and terminal operations. The main drawbacks are emissions of CO2, NOx and other pollutants. LÄS MER
