  1. 6. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  5. 9. Koldioxidabsorption av Gröna Väggar : En utredning av växter på fasader

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Michael Yacob; Hugo Kälström; [2023]
    Nyckelord :;

    Sammanfattning : The pressure on current urban ecosystems is an ongoing problem as greenhouse gaseshave a negative impact on the climate but also on people around the world. As manycities are densely populated, it becomes difficult to introduce more greenery into citieswithout taking up a lot of space, for example by building parks. LÄS MER

  7. 10. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :David Stridfeldt; Jonsson Gustav; [2023]
    Nyckelord :Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

    Sammanfattning :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. LÄS MER
