  1. 16. Quantum Landau-Lifshitz-Gilbert Dynamics of a Dimer

    Master-uppsats, Uppsala universitet/Teoretisk fysik; Uppsala universitet/Materialteori

    Författare :Lee Johnson; [2022]
    Nyckelord :;

    Sammanfattning : The classical Landau-Lifshitz-Gilbert (LLG) equations are of crucialimportance in micro-magnetism, but a true quantum-mechanical descriptionwas not found until 2013. However, very few realistic quantumsystems have been modeled using it. LÄS MER

  3. 17. Quantum Computing in Nuclear Physics

    Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Luca Bernecker; [2022]
    Nyckelord :quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

    Sammanfattning : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. LÄS MER

  4. 18. Training AI for asset pricing

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Axel Jernbäcker; Henrik Angelstig; [2022]
    Nyckelord :AI; Machine learning; Asset pricing; stock price prediction; time-weighting;

    Sammanfattning : This bachelor's thesis examines how a machine learning program's ability to predict stock prices is affected by how the data on which the program is trained has been time-weighted. Building upon the work by Gu, Kelly, and Xiu (2020), we examine how the same machine learning program performs when its training data is time-weighted using one of three methods: exponential weighting, linear weighting, or cutoff.

  5. 19. Estimation of Water Depth from Multispectral Drone Imagery : A suitability assessment of CNN models for bathymetry retrieval in shallow water areas

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

    Författare :Qianyao Shen; [2022]
    Nyckelord :Bathymetry Retrieval; Multispectral Imagery; Convolutional Neural Network CNN ; Hämtning Av Batymetri; Multispektrala Bilder; Konvolutionellt Neuralt Nätverk CNN ;

    Sammanfattning : Aedes aegypti and Aedes albopictus are the main vector species for dengue disease and zika, two arboviruses that affect a substantial fraction of the global population. These mosquitoes breed in very slow-moving or standing pools of water, so detecting and managing these potential breeding habitats is a crucial step in preventing the spread of these diseases.

  7. 20. An investigation of the design of cylinderical steel tanks modelled according to EN14015 and according to the Eurocodes

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Yonas Gebre; [2022]
    Nyckelord :Keywords: Steel tank; Wind; Snow; FEM; Shell buckling; Non-linear analysis;

    Sammanfattning : Abstract Storage tanks are above or below ground vessels for storing chemicals, petroleum and other liquid products. Above ground vertical cylindrical shells are typically thin walled structures prone to buckling and lose their stability especially when they are empty or have lower fluid level due to external loads.
