  2. 1. Sustainable snow handling

    Author : Karin Reinosdotter; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Urban snow contains pollution that originates from sources such as atmospheric precipitation, traffic emission, and de-icing chemicals. These pollutants accumulate in the snow during the winter and are released when the snow starts to melt. READ MORE

  4. 2. Above Ground Durability of Swedish Softwood

    Author : Åsa Blom; Mikael Bergström; Thomas Thörnqvist; Birger Eikenes; Växjö universitet; []
    Keywords : above ground; durability; field test; mass loss; Mycologg; Norway spruce; permeability; Picea abies; Pinus sylvestris; Scots pine; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : This thesis describes aspects of durability of Swedish softwood in above ground applications. The thesis consists of a summary of nine papers, which all aim to explain the existing variation in above ground microbial durability and moisture sensitivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris).

  5. 3. Safety Culture in Sea and Aviation Transport

    Author : Åsa Ek; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organizational climate; air traffic control; safety culture; passenger shipping; airport ground handling; Social sciences; Samhällsvetenskaper; Development psychology; Utvecklingspsykologi; Applied and experimental psychology; Tillämpad och experimentell psykologi; Technological sciences; Teknik; Säkerhetsteknik; Safety technology;

    Abstract : The research presented in this thesis investigates sea and aviation transport safety culture, with a focus on perceptions and attitudes. A safety culture reflects the attitudes, beliefs, perceptions, and values that individuals share in relation to safety. READ MORE

  6. 4. Aerodynamics simulations of ground vehicles in unsteady crosswind

    Author : Tristan Favre; Gunilla Efraimsson; Michael Leschziner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Detached-Eddy Simulations; Crosswind; Aerodynamics; ;

    Abstract : Ground vehicles, both on roads or on rail, are sensitive to crosswinds and the handling, travelling speeds or in some cases, safety can be affected. Full modelling of the crosswind stability of a vehicle is a demanding task as the nature of the disturbance, the wind gust, is complex and the aerodynamics, vehicle dynamics and driver reactions interact with each other.

  7. 5. Numerical Investigation of Unsteady Crosswind Aerodynamics for Ground Vehicles

    Author : Tristan Favre; Gunilla Efraimsson; Mattias Chevalier; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamics; Vehicle Aerodynamics; Unsteady Aerodynamics; Crosswind; Unsteady Crosswind Aerodynamics; Detached-Eddy Simulations; DES; Vehicle engineering; Farkostteknik; Fluid mechanics; Strömningsmekanik;

    Abstract : Ground vehicles are subjected to crosswind from various origins such as weather, topography of the ambient environment (land, forest, tunnels, high bushes...) or surrounding traffic. READ MORE
