  1. 1. Hållbar utveckling och miljöundervisningstraditioner i läromedel för kursen fysik 1 på gymnasiet : En kvalitativ innehållsanalys

    Uppsats för yrkesexamina på avancerad nivå, KTH/Lärande

    Författare :Simon Karlsson; [2022]
    Nyckelord :physics; sustainable development; teaching tradition about the environment; SSI; fysik; hållbar utveckling; miljöundervisningstraditioner; SNI;

    Sammanfattning : Vi lever i en tid av förändring med många utmaningar och komplexa problem som dagens ungdomar möts av i vardagen. Dagens ungdomar är medvetna om miljöproblemen men tycker inte de lösningar som presenteras i skolan fungerar. De känner maktlöshet och hopplöshet inför framtiden. LÄS MER

  3. 2. 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

  4. 3. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

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

    Författare :Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
    Nyckelord :air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

    Sammanfattning : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). LÄS MER

  5. 4. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

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

    Författare :Johan Lundberg; [2021]
    Nyckelord :Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Sammanfattning : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters. LÄS MER

  7. 5. Delivering sustainable energy transition : A techno-economic analysis on households, businesses and communities of the Keweenaw Peninsula

    Master-uppsats, KTH/Energiteknik

    Författare :Francesca Longobardi; Filippo Padovani; [2020]
    Nyckelord :;

    Sammanfattning : Energy security understood as the practice by which risks associated with interruptions to the energy supply are low, represents one of the main objectives of energy policies in many countries. In this context, Keweenaw County or Michigan's northernmost County is placed as locked in an unreliable, unsustainable and particularly wasteful energy system. LÄS MER
