  1. 1. An Infrared Stellar Thermometer: Exploiting IGRINS Spectra

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Emelie Sandved; [2022]
    Nyckelord :Effective temperature; K-giants; surface gravity; oxygen abundance; carbon abundance; CO lines; OH lines; line sensitivities; Physics and Astronomy;

    Sammanfattning : Using the infrared (IR) spectral range when measuring stellar spectra is beneficial compared to using the optical range mainly when observing distant stars through the dust dense interstellar regions in the Galactic mid-plane. Methods to determine stellar parameters from IR spectra are, however, not fully developed yet because technological difficulties in creating reliable IR detectors have slowed the advance of such methods.

  3. 2. Temperature measurement in flames using TLAF, alkali emission and OH UV absorption

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Yuhe Zhang; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a continued need for reliable and convenient nonintrusive thermometric techniques for better understanding and effective control of combustion related processes. In this thesis, three spectroscopic thermometric methods were studied to evaluate the hot flue gas temperatures provided by a multi-jet burner. LÄS MER

  4. 3. Mälarängsskolan F-6

    Kandidat-uppsats, KTH/Arkitektur

    Författare :Lukas Lyttkens; [2018]
    Nyckelord :Architecture; school; Stockholm; Sweden; arkitektur; skola; F-6; Mälaräng; Mälarängen; Stockholm; Sverige; KTH;

    Sammanfattning : Platsen för tomten är i Mälaräng, mellan Bredäng och Mälarhöjden. Bredäng och Mälarhöjden är områden som har stora skillnader när det gäller bl.a. befolkningstäthet och medianinkomst. LÄS MER

  5. 4. Grab Them By The Laugh : An analysis of South Park’s satire on Donald J. Trump and his Presidential Campaign

    Kandidat-uppsats, Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

    Författare :Kristoffer Hangvar; Christian Norgren; [2018]
    Nyckelord :South Park; Donald Trump; satire; analysis; sitcom; cartoon; American; politics; parody; irony; pastiche; caricature.;

    Sammanfattning : The purpose of this bachelor’s thesis is to analyse how the American adult cartoon sitcom South Park (Parker & Stone, 1997) is criticising Donald J. Trump and his presidential campaign through the use of satire and the relative tools of satire. LÄS MER

  7. 5. Near-infrared optical frequency comb Vernier spectroscopy in air and in a flame

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Maryam Fakhri; [2017]
    Nyckelord :;

    Sammanfattning : A Vernier spectrometer is built with a near-infrared mode-locked Er:doped fiber laser, a Fabry-Perot cavity with finesse of 1000, a diffraction grating and a photo detector. The optical cavity provides high sensitivity in absorption detection by enhancing the interaction length of the light with molecular species contained in the cavity. LÄS MER
