  1. 6. Floor vibration : dynamic properties and subjective perception

    Författare :Fredrik Ljunggren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. LÄS MER

  5. 9. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

    Författare :Mikael Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

    Sammanfattning : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. LÄS MER

  7. 10. Dynamic Rating with Applications to Renewable Energy

    Författare :Kateryna Morozovska; Patrik Hilber; Tor Laneryd; Hans Ezz Edin; Adamantios Marinakis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic rating; dynamic line rating; dynamic transformer rating; power transformers; power system optimization; wind farm planning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating.
