  1. 1. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Fredrik Plane; [2022]
    Nyckelord :Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Sammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER

  3. 2. Initial access in 5G mmWave networks with different base station parameters

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Sammanfattning : In recent years, mobile robots have gained tremendous attention from the entire society: the industry is aiming at selling more intelligent products while the academia is improving their performance from all perspectives. Real world examples include autnomous driving vehicles, multirotors, legged robots, etc. LÄS MER

  5. 4. Quantum Gauge Fields in Cosmology: Cosmic Inflation and Gravitational Waves

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Emma Hermansson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis, the consequences of introducing Yang-Mills fields into cosmology are investigated. This is done by the effective action approach, in which the coupling constant is allowed to depend on the quantum fields. LÄS MER

  7. 5. Digital Transformation of B2B Sales Organisations : A case study of a Swedish paper manufacturer

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :André Yang Melsom; Davina Maria Plum; [2022]
