  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Lucy Chipondoro; [2024]
    Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

    Sammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER

  3. 2. The Sustainable Era - The Excess Return on Swedish Sustainable Global Equity Funds

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Kristoffer Holmgren; Måns Hurtigh; [2023-07-03]
    Nyckelord :Fama-French; ESG; Morningstar; Morningstar Globe Rating; funds; global equity funds; sustainability; excess return;

    Sammanfattning : This thesis explores the relationship between the performance of Swedish global equity funds and the level of sustainability, as measured by the Morningstar Globe Rating, using a Fama-French six-factor model, globe rating categories, and time effects. Treating the Morningstar Globe Rating as a time-invariant variable, a sample of 80 Swedish global equity funds are divided into two sustainability groups, ‘Low’ and ‘High’, grouping funds with 1-3 globes into a reference group.

  4. 3. A Machine Learning Approach to Skin Cancer Delineation on Photoacoustic Imaging

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Alice Fracchia; [2023]
    Nyckelord :Skin cancer; carcinoma; photoacoustic imaging; ultrasound imaging; machine learning; dimensionality reduction; sandpiles algorithm; active contour; multilayer perception MLP ; convolutional neural networks CNN ; autoencoder; Physics and Astronomy;

    Sammanfattning : Skin cancer is a growing public health concern due to its prevalence among the population. Current clinical procedures require high invasiveness and multiple surgeries, which are responsible for patient discomfort and high medical expenses. LÄS MER

  5. 4. Simulation Based Methods for Credit Risk Management in Payment Service Provider Portfolios

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Knut Dahlström; Carl Forssbeck; [2023]
    Nyckelord :Credit Risk; Monte Carlo simulation; Importance Sampling; Merton; Kreditrisk; Monte Carlo simulation; Importance Sampling; Merton;

    Sammanfattning : Payment service providers have unique credit portfolios with different characteristics than many other credit providers. It is therefore important to study if common credit risk estimation methods are applicable to their setting. LÄS MER
