    University essay from KTH/Matematisk statistik

    Author : Erik Jonsäll; Emma Mattsson; [2023]
    Keywords : 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.;

    Abstract : 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. READ MORE

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

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anna Åhlström; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 3. Robust Supervised Learning in Multiple Environments

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Xinran Wei; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

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

    Abstract : 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. READ MORE
