    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE

  3. 7. A simplified model for the design of floor structures with vibrating sources for architectural applications

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Rebecca Janson; [2019]
    Keywords : ;

    Abstract : When designing a building, sound is one of the problems to take into account. Vibrating machines, such as ventilation fans, water pumps and compressors, generate structure-borne sound. The structure-borne sound travels up the structure of the building and generates sound in adjacent rooms. READ MORE
