  1. 1. The tangled Warp of the Milky Way

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

    Författare :Viktor Hrannar Jónsson; [2023]
    Nyckelord :Galaxy: structure; Galaxy: kinematics and dynamics; Galaxy: disk; Galaxy: evolution; Physics and Astronomy;

    Sammanfattning : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. LÄS MER

  3. 2. Molns inverkan på satellitdetektion av vegetationsbränder i Sverige

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Marcus Letalick; [2022]
    Nyckelord :clouds; satellite detection; VIIRS; active fires; forest fire; grass fire; FRP; NOAA-20; Suomi-NPP; JPSS; moln; satellitdetektion; VIIRS; skogsbrand; gräsbrand; vegetationsbrand; FRP; NOAA-20; Suomi-NPP; JPSS;

    Sammanfattning : Results are presented from the 2021 test run of active fire detection using the Visual Infrared Imaging Radiometer Suite (VIIRS) instrument, that is currently onboard the polar satellites Suomi-NPP and NOAA-20. The test is performed by the Swedish Civil Contingencies Agency and the Swedish Meteorological and Hydrological Institute, in cooperation with local fire departments in Sweden. LÄS MER

  4. 3. 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.

  5. 4. A comparison between on-premise and cloud environments in terms of security : With an emphasis on Software-as-a-Service & Platform-as-a-Service

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Oliver Byström; [2022]
    Nyckelord :on-premise; cloud; comparison; cybersecurity; metric; on-premise; moln; jämförelse; cybersäkerhet; mått;

    Sammanfattning : Background: Cloud- and on-premise environments have been compared in terms of security several times. Many of these comparisons based their assessments on qualitative data rather than quantitative metrics. Some recent articles have considered comparing environments by using quantitative data.

  7. 5. Molnens påverkan på jordens strålningsbalans och klimatsystem

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Hans Jägfeldt; [2022]
    Nyckelord :moln; kondensation; aerosol; strålningsbalans; klimat; klimatsystem; kosmisk strålning; troposfären; Earth and Environmental Sciences;

    Sammanfattning : The role of clouds in the climate system has been studied and their impact on the Sun's impact on the Earth's energy balance. The Earth's albedo affects the energy balance by influencing how much of the Sun’s radiation is reflected or absorbed. Clouds affect the Earth's albedo and therefore play an important role in this balance. LÄS MER
