  1. 1. A Novel Method for Finding Overlap Depth : Development of ArtiaX, a ChimeraX plugin

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Gunnar Arctaedius; [2023]
    Keywords : Cryo-electron tomography; image processing; surface visualization; overlap measurement; normal projection method; Kryoelektrontomografi; bildbehandling; ytvisualisering; överlapsmätning; normalprojektionsmetoden;

    Abstract : Visualization and image filtering are important parts of cryo-electron tomography analysis. ArtiaX, a plugin developed for UCSF ChimeraX, has been extended to improve the functionality of these two parts. For the visualization, a method of moving 3D surfaces to remove overlap between them has been developed and implemented. READ MORE

  3. 2. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    University essay from Uppsala universitet/Materialteori

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

    Abstract : 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. READ MORE

  4. 3. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Anton Fetzer; [2022]
    Keywords : GTO; Foresail-2; CubeSat; Radiation Shielding; Geant4; Radiation Belts; GTO; Foresail-2; CubeSat; säteilysuojaus; Geant4; säteilyvyöhyke;

    Abstract : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.

  5. 4. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit

    University essay from Stockholms universitet/Fysikum

    Author : Guillermo Lopez Basurco; [2022]
    Keywords : Geant4; Monte Carlo simulations; XFEL undulators; gamma radiation flux;

    Abstract : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. READ MORE

  6. 5. Study of hole mobility in amorphous polyethylene via kinetic Monte Carlo methods

    University essay from KTH/Matematik (Avd.)

    Author : Hannes Aspåker; [2022]
    Keywords : ;

    Abstract : This thesis presents a study of hole mobility in amorphous polyethylene using kinetic Monte Carlo (KMC) methods together with a novel chain segmentation model developed by Unge and Nilsson, which determines hole localization sites based on torsion angles along the polymer chain. An extension to the KMC algorithm was developed which improves performance by modelinground-trips between strongly interconnected localization sites. READ MORE
