  1. 26. Optimizing the design of two-stage ditches to improve nutrient and sediment retention

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofia Englund; [2020]
    Keywords : eutrophication; water quality; mitigation measure; two-stage ditch; retention time; water retention; nutrients; sediments; vegetation; terrace; HEC-RAS; Manning’s coefficient; water level; climate change; övergödning; vattenkvalitet; begränsande åtgärd; tvåstegsdike; retentionstid; vattenretention; näringsämnen; sediment; vegetation; terrass; HEC-RAS; Manning’s koefficient; vattennivå; klimatförändring;

    Abstract : Negative effects on water quality are created by eutrophication of the world’s water resources. Mitigation measures have been implemented, but poor improvements in water quality have been observed. Two-stage ditches have the possibility to increase nutrient and sediment retention to reduce eutrophication in receiving water bodies. READ MORE

  3. 27. Design of Low-Power Wide-Area Networks at Sea

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Michiel Sandra; [2020]
    Keywords : Internet of things; maritime communications; low-power wide-area networks; path loss modeling; Technology and Engineering;

    Abstract : The development of low-power wide-area (LPWA) technologies has opened up for the deployment of wireless networks for new Internet of Things (IoT) applications. One of these is the monitoring of buoys at sea, which tend to detach due to ice, stormy weather or collision with boats, etc. READ MORE

  4. 28. A transformation of a garment company from offline to online - an analysis with solutions based on SWOT and Enterprise Modeling : A case study on a small traditional enterprise

  5. 29. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.
