  1. 1. 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

  3. 2. 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

  4. 3. Nonlinear Methods of Aerodynamic Data-driven Reduced Order Modeling

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Arvid Forsberg; [2022]
    Keywords : machine learning; aerodynamics; autoencoder; kernel transformation; principal component analysis; nonlinear; regression; modeling; surrogate model; reduced order modeling; neural network;

    Abstract : Being able to accurately approximate outputs of computationally expensive simulations for arbitrary input parameters, also called missing points estimation, is central in many different areas of research and development with applications ranging from uncertainty propagation to control system design to name a few. This project investigates the potential of kernel transformations and nonlinear autoencoders as methods of improving the accuracy of the proper orthogonal decomposition method combined with regression.

  5. 4. Precision Tailoring Cooling Systems using Linear Regression

    University essay from KTH/Matematisk statistik

    Author : Kajsa Bjelle; Ida Cui; [2021]
    Keywords : Regression analysis; nonlinear regression; linear regression; Levenberg-Marquardt; applied mathematics; friction factor; wavy fin; bachelor thesis; Regressionsanalys; ickelinjär regression; linjär regression; Levenberg-Marquardt; tillämpad matematik; friktionsfaktor; wavy fin; kandidatexamensarbete;

    Abstract : This bachelor thesis is written for KTH Royal Institute of Technology and Ymer Technology AB. It examines the friction factor associated with the pressure drop in wavy-fin heat exchangers. Previous studies have used a nonlinear approach for determining the regression coefficients. READ MORE

  6. 5. Bank risk analysis with machine learning

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Viet Vu; Mariaguadaloppe Farah; [2021]
    Keywords : ;

    Abstract : Nowadays, the time and resources needed to get an accurate estima-tion of a client’s ability to pay back a loan has gone up. With theamount of data complexity it involves to do the credit risk analysis, the machine learning technique has been used to ease the process. READ MORE
