  1. 11. Energy Quality Management for New Building Clusters and Districts

    Författare :Hai Lu; Martinac Ivo; Hasan Ala; KTH; []
    Nyckelord :;

    Sammanfattning : The level of concern regarding the total energy consumption in new building clusters and urban districts (BCDs) has increased recently. Rising living standards have led to a significant increase in building energy consumption over the past few decades. A great potential for energy savings exists through energy quality management (EQM) for new BCDs. LÄS MER

  3. 12. Absorption of vibration energy in the human hand and arm

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

    Sammanfattning : The risk assessment of hand-arm transmitted vibration is today based on measurements of the magnitude, frequency spectra and duration of the vibration stimuli. It is, however, reasonable to assume that the detrimental effects might depend on the vibration energy absorbed by the hand and arm. LÄS MER

  4. 13. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

    Författare :Muhammad Gufran Khan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

    Sammanfattning : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. LÄS MER

  5. 14. Thermal Modeling of Walls, Foundations and Whole Buildings Using Dynamic Thermal Networks

    Författare :Eva-Lotta Wentzel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walls; weighting functions; Dynamic thermal networks; building; dynamic heat conduction; foundation; step-response functions;

    Sammanfattning : The modeling of the energy balance of buildings is a major task in building physics. A new theory called dynamic thermal networks is under development at the Building Physics Research Group at Chalmers. The calculations are based on step-response functions, and the problems are illustrated in so-called dynamic networks. LÄS MER

  7. 15. Noise emissions from sustainable transport : A multi-scale modeling approach

    Författare :Johan Nygren; Susann Boij; Romain Rumpler; Ciarán J. O'Reilly; Eoin King; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic simulation; sustainable transport; environmental noise; vehicle acoustics; energy efficiency; Trafiksimulering; hållbar transport; samhällsbuller; fordonsakustik; energieffektivitet; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).
