  1. 16. Classical motion in synthetic monopole fields

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Ola Carlsson; [2022]
    Nyckelord :;

    Sammanfattning : In the Born-Oppenheimer approximation for a quantum system the emergent synthetic magnetic field can be seen as generated by monopoles at points of degeneracy, in full analogue to the synthetic fields generating the geometric phase of adiabatically evolving quantum systems. The plausibility of using these synthetic magnetic monopoles as a means to study magnetic monopole dynamics in the absence of fundamental magnetic monopoles has been explored. LÄS MER

  3. 17. 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

  4. 18. Hardware-In-the-Loop Simulation of MIST Attitude Determination and Control System

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

    Författare :Alejandro Vicario; [2022]
    Nyckelord :Functional Testing; HIL; FlightSimulations; ADCS; TestManager; TestStand; Satellite subsystems; Funktionell testning; HIL; flygsimuleringar; ADCS; testledare; TestStand; satellitsub system;

    Sammanfattning : The MIST(MIniature Student saTellite) project is a 3U CubeSat developed by student teams at KTH Royal Institute of Technology in Stockholm. One of the fundamental systems of the satellite is the Attitude Determination and Control System (ADCS), re sponsible for estimating and correcting the satellite’s orientation using magnetic fields and sun sensors.

  5. 19. Quantification of Fatty Acid Composition in Short T2* Tissue Using MRI – Comparison of 3 T and 7 T

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Felix Månsson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: To optimize a method and develop an algorithm to quantify Fatty Acid Composition (FAC) in bone marrow adipose tissue. By using different reconstruction models, compare different MRI systems (3 T and 7 T) to find the optimal field strength and reconstruction model for FAC quantification. LÄS MER

  7. 20. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Clara Sjödin; [2022]
    Nyckelord :magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

    Sammanfattning : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. LÄS MER
