  1. 1. Oscillations in a complex sunspot: From theory to data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Femke Kranenbarg; [2024]
    Nyckelord :;

    Sammanfattning : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. Determining the alignment of Solar Orbiter instruments STIX and EUI during solar flares

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Sofia Tynelius; [2022]
    Nyckelord :Solar flares; the Sun; STIX; EUI; alignment; pointing;

    Sammanfattning : Solar Orbiter is a mission launched in 2020 that will take images closer than ever of the Sun. It has ten instruments on board, including The Spectrometer/Telescope for Imaging X-rays (STIX) and The Extreme Ultraviolet Imager (EUI). LÄS MER

  4. 3. Vidareutveckling av brännarenhet till biogasfackla

    M1-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Johansson Magnus; Mohammad Karoum; [2022]
    Nyckelord :Biogas; metan; biogasfackla; fackla; brännare;

    Sammanfattning : This thesis in mechanical engineering has been conducted in collaboration with Camatec Industriteknik AB, to find new concepts for the burner of biogas flares from Biogas Systems AB. Biogas flares are needed to burn off surplus volumes that arise for various reasons during the extraction of biogas.

  5. 4. Tracking Under Countermeasures Using Infrared Imagery

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Sara Modorato; [2022]
    Nyckelord :computer vision; infrared imagery; tracking; countermeasures; discriminative correlation filters; Efficient Convolution Operator tracker; Spatial-Temporal Regularized Correlation Filter tracker; Visual Object Tracking; flare; DIRCM; multiple wavelength bands; features;

    Sammanfattning : Object tracking can be done in numerous ways, where the goal is to track a target through all frames in a sequence. The ground truth bounding box is used to initialize the object tracking algorithm. Object tracking can be carried out on infrared imagery suitable for military applications to execute tracking even without illumination. LÄS MER

  7. 5. Analysing gene expression of IFN-ɑ stimulated genes in patients with SLE using direct and indirect methods

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Linn Israelsson; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Systemic Lupus Erythematosus (SLE) is an autoimmune disease where the immune system is attacking the body and its tissues. This leads to a chronic inflammation that can affect different parts of the body and therefore present itself in a vast variety of symptoms. LÄS MER
