  1. 1. Phase Unwrapping MRI Flow Measurements

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Mio Liljeblad; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Magnetic Moment Characterization for Small Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Alejandro Sans Monguiló; [2021]
    Keywords : small satellite; CubeSat; optical magnetic test bed; magnetic dipole moment characterization; residual magnetic moment; permanent magnet verification; magnetic measurement; Foresail-1; Helmholtz cage;

    Abstract : Small satellites are gaining popularity in a wide range of applications where attitude systems require high precision performance. One of the main sources of errors, in case of magnetic attitude control systems, is the residual magnetic moment (RMM) of the spacecraft. READ MORE

  4. 3. Determination and compensation of magnetic dipole moment inapplication for a scientific nanosatellite mission

    University essay from KTH/Rymd- och plasmafysik

    Author : Csaba Jéger; [2017]
    Keywords : cubesat; magnetic dipole estimation; attitude dynamics; cubesat; magnetisk dipol uppskattning; attityddynamik;

    Abstract : SEAM (Small Explorer for Advanced Missions) is a 3U CubeSat developedat KTH Royal Institute of Technology which will provide highqualityDC and AC magnetic field measurements of Earth’s magneticfield. The measurement system requires extended periods of timeup to 1000 seconds without active attitude control. READ MORE

  5. 4. Investigation of the electron density close to the rings of Saturn and Prediction of the F-ring plasma characteristics

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : George Xystouris; [2016]
    Keywords : ;

    Abstract : Saturn has the second strongest magnetic field among the planets of the solar system, creating the second biggest magnetosphere, after Jupiter. The magnetosphere is similar to Earth's, as both of them are created by a dipole magnetic field, produced by a planetary dynamo. Despite the similarities, they have some major differences. READ MORE

  6. 5. Motion Tracking Using a Permanent Magnet

    University essay from Reglerteknik; Tekniska högskolan

    Author : Jacob Antonsson; [2013]
    Keywords : ;

    Abstract : In this project the possibility of using a network of magnetometers sensing a permanent magnet for tracking has been investigated. Both the orientation and the position of the magnet have been considered. A dipole approximation of the magnetic field is used to develop two models. READ MORE
