  1. 1. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Erik Fridén; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. LÄS MER

  3. 2. 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

  4. 3. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jules Reniaud; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER

  5. 4. Concept Population & Verification of Traction Motors

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Aditya Pratap Singh; [2021]
    Nyckelord :Synchronous Reluctance Motor SynRM ; Permanent Magnet Synchronous Motor PMSM ; Permanent Magnet assisted SynRM PM-SynRM ; traction motors; electrical machines; Synkron Reluktansmotor; Permanent Magnet Synkron motor; Permanent Magnet assisterad Synkron motor; framdrivningsmotorer; elmotorer;

    Sammanfattning : The electrification of automobiles has emerged as the sustainable powertrain solutionto meet United Nations sustainable development goals of sustainable cities andcommunities, affordable and clean energy, and climate action. The success of theelectrification depends on the efficiency of traction motors. LÄS MER

  7. 5. Permanent magnet synchronous machine using ferrite vs rare earth magnets : how do they compare?

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

    Författare :Nikhil Manakshya; [2021]
    Nyckelord :Vehicle requirement; drive cycle; ferrite magnet; demagnetisation; environmental impact.; Fordonsbehov; körcykel; ferritmagnet; avmagnetisering; miljöpåverkan.;

    Sammanfattning : Permanent magnet synchronous machines (PMSM are considered as viable options for automotive and traction applications. Rare earth magnets such as Neodymium Iron Boron (NdFeB is the most common choice in the PMSM for electric vehicles to achieve high power density machines. LÄS MER
