  1. 1. Phase Unwrapping MRI Flow Measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Mio Liljeblad; [2023]
    Nyckelord :phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Sammanfattning : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. LÄS MER

  3. 2. Error propagation in nuclear models

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

    Författare :Artis Mucenieks; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  4. 3. Assessing the Impact of Ocean Proximity and a Nuclear Power Plant on Property Values : a Hedonic Price Study in Östhammar

    Kandidat-uppsats, SLU/Dept. of Economics

    Författare :Louise Nordmark Strandberg; [2023]
    Nyckelord :Hedonic pricing; property pries; natural environment; Nuclear power plant; coastline;

    Sammanfattning : This study examines the impact of environmental attributes, specifically proximity to the ocean and a nuclear power plant, on property prices in Östhammar municipality during the period of 2017-2022. By conducting a hedonic price model for evaluating non-market goods, a dataset of 1210 observations of family houses and vacation homes was analyzed. LÄS MER

  5. 4. Samband mellan nukleära avvikelser i tvåcellsstadiet hos embryon efter assisterad befruktning och chans till graviditet och levande fött barn

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Helbeen Sadullah; [2023]
    Nyckelord :Assisted fertilization; nuclear errors; multinuclearity; embryo assessment; Assisterad befruktning; nukleära avvikelser; multinukleäritet; embryobedömning;

    Sammanfattning : Bakgrund Assisterad befruktning är en vanlig behandling för infertilitet, vilket innebär oförmågan att bli gravid. Vid assisterad befruktning övervakas embryoutvecklingen med hjälp av Time Lapse Imaging-teknologi i en EmbryoScope och implantationsförmågan bedöms. LÄS MER

  7. 5. Anomaly detection with machine learning methods at Forsmark

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Simon Sjögren; [2023]
    Nyckelord :machine learning; nuclear power; nuclear power plant; anomaly detection; anomaly; data processing; data-driven; autoencoder; maskininlärning; kärnkraft; kärnkraftverk; Forsmark; anomalidetektion; anomali; databehandling;

    Sammanfattning : Nuclear power plants are inherently complex systems. While the technology has been used to generate electrical power for many decades, process monitoring continuously evolves. There is always room for improvement in terms of maximizing the availability by reducing the risks of problems and errors. LÄS MER
