  1. 1. Uncertainty quantification for offshore wind turbines

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Ziming Wang; [2022]
    Nyckelord :wind energy; uncertainty propagation; polynomial chaos; Rosenblatt transformation; quadrature; regression; vindenergi; osäkerhetsutbredning; polynomkaos; Rosenblatt transformation; kvadratur; regression;

    Sammanfattning : Wind energy is a field with a large number of uncertainties. The random nature of the weather conditions, including wind speed, wind direction, and turbulence intensity, influences the energy output and the structural safety of a wind farm, making its performance fluctuate and difficult to predict.

  3. 2. Improving SARS-CoV-2 analyses from wastewater

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Israa Yahia Al Hag Ibrahim Dafalla; [2021]
    Nyckelord :;

    Sammanfattning : Wastewater-based epidemiology (WBE) analyzes wastewater for the presence of biological and chemical substances to make public health conclusions. COVID-19 disease is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that infected individuals shed also in their feces, making WBE an alternative way to track SARS-CoV-2 in populations.

  4. 3. Determining the Sensitivity of Reactor Parameters in a Sodium Cooled Fast Reactor

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Alexander Palfelt; Wilhelm Thunberg; Anders Winka; [2020]
    Nyckelord :serpent; SFR; sodium cooled fast reactor; generation 4;

    Sammanfattning : The sensitivity of two operational output parameters, criticality and isotopic composition during burnup, to specific design and operational reactor parameters in a Sodium Cooled Fast Reactor, is investigated. The computational simulation tool Serpent is used. LÄS MER

  5. 4. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Honorine Uwera; [2020]
    Nyckelord :turbidity; suspended sediments; dissolved organic matter; optical measurements;

    Sammanfattning : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). LÄS MER

  7. 5. Classifying forest stands according to spatial species mingling

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource Management

    Författare :Arvid Svensson; [2018]
    Nyckelord :quantitative ecology; forest biometrics; forest structure; biodiversity function; species mingling;

    Sammanfattning : Legislature and international treaties increasingly underline the importance of biodiversity and sustainability, hence the need for accurate measurements, regarding the aforementioned concepts. Biodiversity is a comprehensive term, which can be very difficult/costly to measure directly. LÄS MER
