  1. 1. The visibility of stellar transients in the Galactic Centre

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

    Författare :Jonathan Ström; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. LÄS MER

  3. 2. Preliminary Design and Conceptual Analysis of an Electrically Actuated Pintle Injector

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Simone Guietti; [2024]
    Nyckelord :Pintle injector; space propulsion; space engineering;

    Sammanfattning : ”The Eagle has landed”. With this words, astronaut Neil Armstrong, together with astronaut Edwin ”Buzz” Aldrin, confirmed the safe landing on the Moon of the Apollo11 on July 20th, 1969. This achievement would have never been possible without the engineering behind the construction of the Moon lander. LÄS MER

  4. 3. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  5. 4. Validering av KFX för vätgasjetflammor som träffar ytor

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonathan Nilsson; [2024]
    Nyckelord :Kameleon FireEX; KFX; CFD; Hydrogen Jetfire; Technology and Engineering;

    Sammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER

  7. 5. Aesthetic Character of Landscape : A Cognitive Account

    Magister-uppsats, Uppsala universitet/Filosofiska institutionen

    Författare :Loki Anne Thompson; [2023]
    Nyckelord :Environmental aesthetics; landscape; applied aesthetics;

    Sammanfattning : In this paper, I present a cognitive account of aesthetic character of landscape. I develop this in response to Emily Brady, who coined the term to refer to the aesthetic individuality of a landscape, which she argues we ought to conserve. LÄS MER
