  1. 6. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Peter Dagbui; [2023]
    Nyckelord :Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Sammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER

  3. 7. Improving polarizing neutron optics by introducing 11B4C as interlayers

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Martin Falk; [2023]
    Nyckelord :Thin film multilayers; Neutron optics; Neutron polarization;

    Sammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER

  4. 8. Frekvensstyrning med Kaplanturbin

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

    Författare :Hemi Strömstedt; [2023]
    Nyckelord :Frequency Containment Reserve; FCR; FCR-N; PID; PI; Frequency Containment Reserve; FCR; FCR-N; PID; PI;

    Sammanfattning : Det här examensarbetet inriktar sig på att med ett simuleringsprogram försöka utröna om det skulle gå att använda feedback control av löphju-let på en kaplanturbin för att reglera frekvensen ut på elnätet. Detta görs idag med hjälp av att öka eller minska magnetiseringen av generatorn. LÄS MER

  5. 9. Development of MOKE spectrometer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Sebastian Åberg; [2023]
    Nyckelord :MOKE; Spectroscopy;

    Sammanfattning : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. LÄS MER

  7. 10. Optimization of MP2RAGE sequence parameters for head and neck T1-mapping and OE-MRI

    Master-uppsats,

    Författare :Ellen Börjesson; [2022-05-04]
    Nyckelord :Medical physics; MRI; OE-MRI; MP2RAGE; T1-mapping;

    Sammanfattning : Cancer is the collective name for more than 200 types of diseases that annually causes the death of 8.8 million people, cancer in the head and neck (H&N) accounts for 330.000 of these. It has been shown that hypoxic tumors are more resistant to treatment than well oxygenated tumors. LÄS MER
