  2. 1. Stand development and growth in uneven-aged Norway spruce and multi-layered Scots pine forests in boreal Sweden

    Author : Martin Ahlström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The use of the selection system has always been a marginal part of Swedish forestry, and so has research about the system under Swedish conditions. However, the interest in Sweden for uneven-aged forest management has increased because of a rising concern for the ecological and aesthetical consequences from use of the dominating rotation forests system, which creates even-aged forest and has clear-cutting as primary harvesting method.

  4. 2. Aerolastic simulation of wind turbine dynamics

    Author : Anders Ahlström; Anders Eriksson; Martin O. L. Hansen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; wind turbine; aeroelastic modelling; rotor aerodynamics; structural dynamics; MSC.Marc; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : The work in this thesis deals with the development of an aeroelastic simulation tool for horizontal axis wind turbine applications. Horizontal axis wind turbines can experience significant time varying aerodynamic loads, potentially causing adverse effects on structures, mechanical components, and power production. READ MORE
