  1. 16. Design and construction of a reliable wireless power transfer system for an embedded device : With emphasis on industrial applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhruvi Ajit Shukla; [2022]
    Keywords : Wireless Power Transfer WPT ; ferrites; Litz wire; skin effect; proximity effect; electromagnetic induction; electromagnetic resonance; magnetic coupling; power efficiency; LC circuits; Trådlös kraftöverföring WPT ; ferrit; litz-tråd; hudeffekt; närhetseffekt; elektromagnetisk induktion; elektromagnetisk resonans; magnetisk koppling; effekteffektivitet; LC-kretsar;

    Abstract : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jules Reniaud; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  4. 18. Characterisation of Satellite Onboard Magnetometer for MIST

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marcus Mhanna; [2022]
    Keywords : Magnetometer calibration; Ellipsoid Fitting; Helmholtz coil;

    Abstract : The most common equipment used for attitude determination in small satellites are magnetometers. However, using magnetometers gives rise to many challenges. One of these challenges is the calibration of the magnetometer. Magnetometer calibration takes many factors into account. READ MORE

  5. 19. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

    University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

    Author : Tova Rung; [2022]
    Keywords : Synthetic CT; Air coil;

    Abstract : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

  6. 20. Shielding of Transformer Stray Fields in Trains

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lárusdóttir Lára Ólafia; [2022]
    Keywords : ;

    Abstract : Generally, a transformer will produce stray magnetic fields. Aboard trains, the transformer’s stray fields can pose problems to other components inside or outside the train. Further, regulations require the magnetic field to be below certain levels in the passenger area. READ MORE
