  1. 41. The Impact of an Offshore Wind Farm on a Power Grid

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

    Författare :Arvid Söderberg; Tim Possekel; [2023]
    Nyckelord :;

    Sammanfattning : Due to increasing power demands and growing importance of sustainability, more and morewind power is being built and connected to existing power systems. While wind power isboth renewable and cost-effective, it is important to note that due to its variable nature, itcan negatively impact the stability of a power system. LÄS MER

  3. 42. Natt-till-natt-variation av andningshändelser vid nattlig andningsregistrering

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Tala Bitar; [2023]
    Nyckelord :Sleep apnea; apnea-hypopnea index; night-to-night variation; polygraphy; Sömnapné; apné-hypopné index; natt-till-natt variation; polygrafi;

    Sammanfattning : Sömnapné karaktäriseras av korta andningsuppehåll som inträffar under sömnen och resulterar i en störd nattsömn. Svårighetsgraden av sömnapné kan anges med hjälp av ett index som kallas för apné-hypopné index (AHI), där summan av alla andningsuppehåll divideras med den totala sömntiden. LÄS MER

  4. 43. Frontal Alpha Asymmetry and Behavioral Inhibition and Activation Systems

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Victoria Saldjoughi Tivander; [2023]
    Nyckelord :frontal alpha asymmetry; EEG; resting-state; BIS BAS; test-retest reliability;

    Sammanfattning : Extensive research has been conducted on the relationship between brain activity and personality traits, and several theories propose a lateralization of specific personality qualities. A prominent model suggests frontal lateralization of motivational direction, specifically, the behavioral inhibition and activation systems (BIS/BAS), with greater right frontal activity linked to behavioral inhibition and greater left frontal activity linked to behavioral activation.

  5. 44. Growth and quality of silver birch with different improvement levels

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Hanna Liebner; [2023]
    Nyckelord :Betula pendula Roth; genetic improvement; tree breeding; diameter growth; stem quality; branches quality;

    Sammanfattning : Silver birch is the most important broadleaf tree species in the context of wood production in Fennoscandia stating 12.9% of the total volume in Sweden (Nilsson et al., 2021). LÄS MER

  7. 45. Ecosystem services from woody vegetation in East African rangelands

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Anna Linnéa Elisabeth Swärd; [2023]
    Nyckelord :dryland ecosystems; rangelands; rangelands; woody vegetation; restoration; Karamoja; West Pokot; pastoralists; agro-pastoralists; East Africa;

    Sammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER
