  1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

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

    Författare :Charlotte Sophie Gausa; [2024]
    Nyckelord :Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

    Sammanfattning : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

  3. 2. Exploring potential E-fuel production pathways for maritime and aviation sectors in France : a techno-economic and environmental assessment

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

    Författare :Mathieu Minaud; [2024]
    Nyckelord :;

    Sammanfattning : The aviation and maritime industries pose significant challenges for decarbonization, having increased activity in the past decade. One promising solution to limit emissions in these sectors is Electrofuels (E-fuel), derived from water electrolysis hydrogen and captured CO2 or nitrogen. LÄS MER

  4. 3. Marktäckets och markfuktighetens påverkan på blomsterlupinens (Lupinus polyphyllus) utbredning i Jämtland

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Julia Svedh; [2024]
    Nyckelord :Garden lupine; Lupinus polyphyllus; soil moisture; land cover; invasive alien species; Jämtland; ; Blomsterlupin; Lupinus polyphyllus; marktäcke; markfuktighet; invasiva främmande arter; Jämtland;

    Sammanfattning : Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. LÄS MER

  5. 4. The Role of Uni- and Multivariate Bias Adjustment Methods for Future Hydrological Projections and Subsequent Decision-Making

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

    Författare :Anna Merle Liebenehm-Axmann; [2024]
    Nyckelord :Bias adjustment methods; future hydrological climate projections; statistical analysis; future streamflow analysis; biasjusteringsmetoder; framtida hydrologiska projektioner; statistisk analys; framtida vattenförings analys;

    Sammanfattning : Climate models are essential for generating future climate projections. However, due to simplifications, the models can produce systematic differences between output and reality, which is referred to as model bias. Bias adjustment methods aim to reduce this error, which is important for making future projections more reliable. LÄS MER

  7. 5. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER
