  1. 1. Development of a model for ionospheric instabilities in the equatorial region

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Thea Lepage; [2023]
    Nyckelord :;

    Sammanfattning : This work is part of a bigger project on analyzing the ionospheric dynamics in the equatorial region using simulations. The main objective of this study is to determine and characterize the parameters needed to trigger instabilities and thus the formation of plasma bubbles. LÄS MER

  3. 2. Cavity Beam Position Monitors State of the Art and Design Studies in the Context of the ILC Project

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Laura Karina Pedraza Motavita; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this master thesis project is the study and evaluation of the design of cavity beam position monitors (BPM) for the International Linear Collider (ILC) project. The state-of-the-art of BPMs is investigated to determine the most appropriate existing BPM design for the requirements of the ILC. LÄS MER

  4. 3. Phase Unwrapping MRI Flow Measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Mio Liljeblad; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Cusp Aurora Appearing at the Dayside tip of Transpolar Arcs - Dependence on IMF and Dipole Tilt

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

    Författare :Cecilie Holmen; Mattias Wang; [2023]
    Nyckelord :;

    Sammanfattning : The aurora is a direct consequence of the Earth’s magnetic field interaction withthe solar wind and the interplanetary magnetic field (IMF). In this study, we examine thelocation of the cusp aurora when accompanied by transpolar arcs (TPAs) with the goal to finda dependence on the IMF. LÄS MER

  7. 5. Simulations of the Tenuous Upper Atmospheres of Exoplanets

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

    Författare :Lucian Spitzner; [2023]
    Nyckelord :astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER
