  1. 11. Anticipating bankruptcies among companies with abnormal credit risk behaviour : Acase study adopting a GBDT model for small Swedish companies

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Heinke; [2022]
    Nyckelord :Bankruptcy prediction; Credit risk analysis; Abnormal credit risk behaviour; Gradient boosted decision trees; SHAP-values.; Konkurs förutsägelse; Kredit riskanalys; Abnomralt kreditbeteende; Gradient baserat beslutsträd; SHAP-värden.;

    Sammanfattning : The field of bankruptcy prediction has experienced a notable increase of interest in recent years. Machine Learning (ML) models have been an essential component of developing more sophisticated models. Previous studies within bankruptcy prediction have not evaluated how well ML techniques adopt for data sets of companies with higher credit risks. LÄS MER

  3. 12. A study of the gamma-ray emission from the blazar S50716+71 using the Fermi-LAT telescope

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Fredrik Vislander; [2022]
    Nyckelord :AGN; active galactic nuclei; Fermi-LAT; astrophysics; gamma-rays; synchrotron self-Compton; SSC; S50716 71.;

    Sammanfattning : This thesis sums up a bachelor project in which gamma-ray emission from an extra-galactic source (S50716+71) is studied using data collected by the Fermi Large Area Telescope (LAT). The emission consists of 12,5 years of data (April 2008 to February 2020) in the energy range 100 MeV - 300 GeV. LÄS MER

  4. 13. Identifying Transit Timing Variations in K2 and TESS light curves

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Linn Friis-Liby; [2022]
    Nyckelord :Exoplanets; TESS; K2; Transit Timing Variations;

    Sammanfattning : Aims. The aim of this work is to investigate any presence of transit timing variations (TTVs) in a sample of observed targets that has light curves in both K2 mission data and TESS mission data.  Methods. The original sample utilised here was one from the doctoral thesis of D. LÄS MER

  5. 14. Modeling Electricity Prices in the German Energy market - with Applications to Renewables

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Kaisen Jin; Chibuzo Azuka; [2022]
    Nyckelord :Hourly Price Forward Curves; Power Market; Renewables; Electricity spot prices; Day-ahead market; Business and Economics;

    Sammanfattning : Recent focus on the negative effects of climate change has amplified the importance of renewable sources of energy for electricity generation. The contribution of renewables to the energy mix is growing steadily with profound effects on the price of electricity and implications for market participants. LÄS MER

  7. 15. Evaluating digital twin data exchange between a virtual and physical environment regarding lighting quantity

    Master-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap
