  1. 21. Understanding the Impacts of Weather and Climate Change on Travel Behaviour

    Författare :Liu Chengxi; Yusak O. Susilo; Karlström Anders; Kelly J. Clifton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; impacts of weather; climate change; travel survey; spatial heterogeneity; activity-travel pattern; weather perception; passenger transport CO2 emission; Transportvetenskap; Transport Science;

    Sammanfattning : Human behaviour produces massive greenhouse gas emissions, which trigger climate change and more unpredictable weather conditions. The fluctuation of daily weather corresponds to variations of everyday travel behaviour. This influence, although is less noticeable, can have a strong impact on the transport system. LÄS MER

  3. 22. Robust Multimedia Communications over Packet Networks

    Författare :Guoqiang Zhang; W. Bastiaan Kleijn; Vinay Vaishampayan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : Multimedia communications over packet networks, and in particular the voice over IP (VoIP) application, have become an integral part of society. However, the unreliable and heterogeneous nature of packet networks has led to a best-effort delivery of services. LÄS MER

  4. 23. Wind turbine wakes : controland vortex shedding

    Författare :Davide Medici; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Energy; Power Optimisation; Active Control; Yaw; Vortex; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : Wind tunnel studies of the wake behind a model wind turbine have been made in order to get a better understanding of wake development as well as the possibility to predict the power output from downstream turbines working in the wake of an upstream one. Both two-component hot-wire anemometry as well as particle image velocimetry (PIV) have been used to map the flow field. LÄS MER

  5. 24. Industrial Bioprocess Developments for Biogas and Ethanol Production

    Författare :Karthik Rajendran; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; ethanol; process design; techno-economic analysis; simulation; modeling; Resource Recovery; Resursåtervinning;

    Sammanfattning : Current biofuels face a noteworthy misfortune on commercialization because of its economiccomparison with low-cost fuel from the oil reserves. To compete with gasoline as a fuel, thebiofuels need to be economically feasible and demonstrated on a large-scale. LÄS MER

  7. 25. Phase transitions and phase frustration in multicomponent superconductors

    Författare :Daniel Weston; Egor Babaev; Mats Wallin; Ilya Eremin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Sammanfattning : Multicomponent superconductors described by several complex matter fields have properties radically different from those of their single-component counterparts. Examples include partially ordered phases and spontaneous breaking of time-reversal symmetry due to frustration between Josephson-coupled components. LÄS MER
