  1. 1. Data Driven Modeling for Aerodynamic Coefficients

    Master-uppsats, KTH/Matematisk statistik

    Författare :Erik Jonsäll; Emma Mattsson; [2023]
    Nyckelord :Master s thesis; System identification; Parameter estimation; Ordinary least squares; Machine learning; Aerodynamic coefficients; F18--HARV; Flight simulations.; Masteruppsats; Systemidentifiering; Parameteruppskattning; Minstakvadratmetoden; Maskininlärning; Aerodynamiska koefficienter; F18-HARV; Flygsimuleringar.;

    Sammanfattning : Accurately modeling aerodynamic forces and moments are crucial for understanding thebehavior of an aircraft when performing various maneuvers at different flight conditions.However, this task is challenging due to complex nonlinear dependencies on manydifferent parameters.

  3. 2. Total body perfusion imaging with 15O-water PET

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Anna Åhlström; [2023]
    Nyckelord :;

    Sammanfattning : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. LÄS MER

  4. 3. Robust Supervised Learning in Multiple Environments

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xinran Wei; [2023]
    Nyckelord :;

    Sammanfattning : In supervised machine learning, it is common practice to choose a loss function for learning predictive models, such as linear regression models and nonlinear neural networks. The primary objective is to attain accurate predictions. LÄS MER

  5. 4. Neural Networks for Modeling of Electrical Parameters and Losses in Electric Vehicle

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Yo Fujimoto; [2023]
    Nyckelord :Artificial neural network; machine learning; random forest; deep learning; electric vehicle; decision tree; k-nearest neighbors; permanent magnet synchronous machine;

    Sammanfattning : Permanent magnet synchronous machines have various advantages and have showed the most superiorperformance for Electric Vehicles. However, modeling them is difficult because of their nonlinearity. LÄS MER

  7. 5. The relationship between the three dimensions of sustainable development

    Kandidat-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Muhammad Nabeel Numan; [2022]
    Nyckelord :Sustainable development; Human development; Human development index; Ecological footprint; Economic complexity; Economic complexity index; Environmental Kuznets curve; Business and Economics;

    Sammanfattning : Sustainable development is a widely discussed concept, and it is needed because the world is facing a massive global challenge of climate change. Sustainable development is envisioned as an all-inclusive concept of three dimensions; environment, economy, and society. However, there are trade-offs between these three dimensions. LÄS MER
