  1. 1. Imbalanced Learning and Feature Extraction in Fraud Detection with Applications

    University essay from KTH/Numerisk analys, NA

    Author : Martin Jacobson; [2021]
    Keywords : Fraud; Fraud Detection; Imbalanced Learning; Feature Extraction; Extreme Learning Machines; ELM; Machine Learning; ML; Bedrägeri;

    Abstract : This thesis deals with fraud detection in a real-world environment with datasets coming from Svenska Handelsbanken. The goal was to investigate how well machine learning can classify fraudulent transactions and how new additional features affected classification. READ MORE

  3. 2. Looking for mono-Z signatures in Z-boson and scalar dark matter interactions

    University essay from Uppsala universitet/Högenergifysik

    Author : Magnus Bertilsson; [2021]
    Keywords : Scalar Dark Matter; Z boson; Mono-Z signatures;

    Abstract : Even though there is a multitude of observational evidence from cosmology and astrophysics, the standard model does not include a suitable dark matter candidate and therefore physics beyond the standard model is necessary. There are hypotheses of what the particle candidate could be coming from theories such as supersymmetry or extra dimensions. READ MORE

  4. 3. Evaluation of thermal expansion in busbars used for battery electric vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : FREDRIK LARSSON; [2021]
    Keywords : Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Abstract : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. READ MORE

  5. 4. Stability analysis and modelling of a structure with corrugated roof

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Nikola Tosovic; [2020]
    Keywords : Technology and Engineering;

    Abstract : Corrugated galvanized iron (CGI), or corrugated sheet metal, is a lightweight roofing material that was invented in the early 1800s. The corrugation gives the steel an increased flexural strength in its installed direction and thus increases the amount of load the CGI-plate is able to carry and the span it can be effective at.

  6. 5. Optimal placement of plasma actuators on trucks : A drag reduction study using adjoint methods

    University essay from KTH/Aeroakustik

    Author : Samuel Gottfarb Bart; [2016]
    Keywords : ;

    Abstract : The fuel consumption of vehicles plays an important environmental role and ways of improving the fuel economy is beneficial for a sustainable future. Active flow control is one method that can potentially reduce the aerodynamic drag significantly and therefore the fuel consumption. READ MORE
