  1. 1. Satellite signal attenuation due to atmospheric influences in northern Sweden

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adrian Stigsson; [2024]
    Nyckelord :;

    Sammanfattning : Earth-space traversing electromagnetic waves become attenuated as they propagate through the atmosphere. The sources of attenuation are weather phenomena in the Troposphere, and scintillation and absorption in the Ionosphere. LÄS MER

  3. 2. Haga Företagscenter - historical and preliminary technical investigation of a contaminated site in Anderstorp, Småland, Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Max Boestam; [2022-12-21]
    Nyckelord :;

    Sammanfattning : The Haga Företagscenter site in Anderstorp, Sweden has a long industrial history, which include the extensive use of chlorinated solvents. Trichloroethene (TCE) was used in large quantities here but the release to the environment has not been previously investigated. LÄS MER

  4. 3. Quantification of peat volume change in Northern peatlands : A study of mires capacity to swell and shrink and its relation to mire age and land management

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anna Engman; [2022]
    Nyckelord :peatland; peat volume change; ecohydrology; specific storage; peatland age; torvmark; myr; torvvolymförändring; ekohydrologi; specifik magasinkoefficient; ålder;

    Sammanfattning : Peatlands are important ecosystems that provide ecohydrological functions related to carbon storage and cycling, water quality, flood attenuation, and groundwater recharge. One key characteristic that gives peatlands these functions is the capacity to swell and shrink upon wetting and drying, commonly referred to as peat volume change. LÄS MER

  5. 4. Modelling of stormwater treatment in biofilters using MIKE+ : Possibilities and limitations

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cecile Bouju; [2021]
    Nyckelord :Biofilter; Raingarden; Stormwater treatment; Stormwater management; Hydrological modelling; MIKE ; ECO Lab; Biofilter; Växtbädd; Dagvattenrening; Dagvattenhantering; Hydrologisk modellering; MIKE ; ECO Lab;

    Sammanfattning : As research has expanded on the environmental impact of stormwater on receiving ecosystems more focus is now being put on the quality issues of stormwater. Biofilters are one of many nature-based solutions that have been developed for that purpose and are also the subject of this study. LÄS MER

  7. 5. User Deployed Hot-Spots in Rurual 5G Networks

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Nasir Zaman; [2019]
    Nyckelord :5G; Rural Networks; Energy Efficiency; User Deployed Hot-Spot;

    Sammanfattning : Cellular network expansion in rural areas has been traditionally slower than in dense urban areas. Area coverage in rural areas is fundamentally limited by the deployment cost for the operator. LÄS MER
