  1. 1. CHANGES IN URBAN GREENERY DURING THE 2018 HEAT WAVE – A CASE STUDY FOR GÖTEBORG USING REMOTE SENSING

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Ivan Ruzic; [2023-06-21]
    Nyckelord :heat wave; urban trees; NDVI; remote sensing;

    Sammanfattning : Urban vegetation plays a crucial role in diverse urban microclimates. The numerous ecosystem services provided by vegetation, particularly trees, ensure greater quality of life and thermal comfort regulation. Yet, not all trees are immune to extreme weather events, such as droughts and heat waves, especially in cities. LÄS MER

  3. 2. Ocean rogue wave analysis for the development of safer navigation systems. : A Thesis submitted to the University of Gävle for the degree of Bachelor of Mathematics

    L3-uppsats, Högskolan i Gävle/Matematik

    Författare :Sergio Manzetti; [2023]
    Nyckelord :;

    Sammanfattning : Rogue waves are unexpectedly high waves of 2.5X the significant wave height and which occur in nearly all phases of nature, from  oceans, to fiber-optic cables and atmospheric air-masses. In the ocean, rogue waves pose a significant danger to shipping and fishing vessels and have been found to reach 27. LÄS MER

  4. 3. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

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

    Författare :Michael Konrad Schutte; [2023]
    Nyckelord :jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

    Sammanfattning : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

  5. 4. Wave Energy Concept Benchmarking

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Petter Larsson; Gustaf Rudbeck; [2021]
    Nyckelord :Budal K; Linear waves; Oscillating water column; Point absorber; Wave energy; Budal K; Linjära vågor; Oscillating water column; Point absorber; Vågenergi;

    Sammanfattning : Denna rapport ämnar undersöka de vanligast förekommande typerna av teknologier för vågkraftverk (eng. Wave Energy Converter, WEC) teknologier för att jämföra de olika konceptens förmåga att absorbera vågenergi. Koncept som undersöks är punktabsorbatorer och oscillerande vattenkolumner. LÄS MER

  7. 5. Modelling the Resilience of Offshore Renewable Energy System Using Non-constant Failure Rates

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Mussie Abraham Beyene; [2021]
    Nyckelord :offshore renewable energy; resilience; wave energy farm; vulnerability; characterization; weather climates; failure rate; wind energy farm; generalized extreme value method; significant wave height; wind speed;

    Sammanfattning : Offshore renewable energy systems, such as Wave Energy Converters or an Offshore Wind Turbine, must be designed to withstand extremes of the weather environment. For this, it is crucial both to have a good understanding of the wave and wind climate at the intended offshore site, and of the system reaction and possible failures to different weather scenarios.
