  1. 21. Uncertainty Estimation in Volumetric Image Segmentation

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

    Författare :Donggyun Park; [2023]
    Nyckelord :Uncertainty Estimation; Uncertainty Quantification UQ ; Volumetric Image Segmentation; 3D U-Net; test-time data augmentation; Deep ensemble;

    Sammanfattning : The performance of deep neural networks and estimations of their robustness has been rapidly developed. In contrast, despite the broad usage of deep convolutional neural networks (CNNs)[1] for medical image segmentation, research on their uncertainty estimations is being far less conducted. LÄS MER

  3. 22. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

    Sammanfattning : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. LÄS MER

  4. 23. Glauber Monte-Carlo Simulation and Model Comparison in High-Energy Collisions

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Sebastião De Sousa Castanheira Miranda; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis, a Glauber Monte-Carlo event generator is developed and used to analyze proton-Ion (p -$^{63}$Cu and p -$^{197}$Au) and Ion-Ion ($^{63}$Cu -$^{63}$Cu and $^{197}$Au -$^{197}$Au) collisions. Three different sub-collision models are implemented, the black disk, grey disk and oscillating grey disk models, and their validity is compared. LÄS MER

  5. 24. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

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

    Författare :Kun Feng; [2023]
    Nyckelord :ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

    Sammanfattning : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. LÄS MER

  7. 25. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Siri Alva Berge; [2023]
    Nyckelord :magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Sammanfattning : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. LÄS MER
