  1. 1. Conform with the Wind : Processing short-term ensemble forecasts with conformal based methods for probabilistic wind-speed forecasting

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Simon Althoff; [2023]
    Nyckelord :wind-speed; probabilistic; forecasts; forecasting; ensemble; post-processing; conformal prediction; conformal predictive systems; quantile regression forest; non-exchangeable; Mathematics and Statistics;

    Sammanfattning : Forecasting wind has always been an interesting subject, and as large parts of the world are relying more on wind for power production it is becoming even more important to have reliable forecasts. Probabilistic forecasts, where distributions are predicted in contrast to deterministic forecasts, are impor- tant for informed decision making. LÄS MER

  3. 2. Coming for the Money, staying for the Community : an analysis of the NFT community

    Master-uppsats, Lunds universitet/Medie- och kommunikationsvetenskap; Lunds universitet/Institutionen för kommunikation och medier

    Författare :Jennifer Kristen; [2022]
    Nyckelord :NFTs; value; sociality; engagement; community; platforms; Social Sciences;

    Sammanfattning : Non-fungible tokens (NFTs) are a type of cryptocurrency that consist of unique, non-exchangeable tokens, which are traded on a blockchain. These unique tokens are associated with digital assets such as images, art, videos, or music. LÄS MER

  4. 3. The evaluation of preparation techniques for the measurements of hydrogen isotope ratios in ecology

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Kusal Weragama; [2021]
    Nyckelord :Deuterium; liquid water equilibration; steam equilibration; exchangeable H fraction; non-exchangeable H; Equilibrium fractionation factor; Isotopic soil fraction;

    Sammanfattning : The stable isotope ratio of non-exchangeable hydrogen (δ2Hn) emerged as a promising new tool for source attribution in aquatic ecology, which can better discriminate between the organic matter sources. However, determining the absolute isotopic values is problematic due to the functional groups with hydrogen (H) that can easily exchange with the ambient water. LÄS MER

  5. 4. Förändring av radiocesiumtillståndet i jordbruksgrödor i Gävleborgs, Västmanlands och Uppsala län efter Tjernobylolyckan samt en fallstudie med stallbalansberäkningar på en mjölkgård

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Johanna Olsson; [2006]
    Nyckelord :137Cs; 40K; cesium; Tjernobylolyckan; kontaminerad jord; radioaktivt nedfall;

    Sammanfattning : Several radioactive nuclides were deposited in Sweden after the Chernobyl accident in 1986. The greatest attention was given to 137Cs because of its relative long physical half life of about 30 years. 137Cs will be present in nature for more than 100 years before it has vanished completely.
