  1. 1. Simulation-Based Stochastic Blockage Model for Millimeter-wave Communication

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mihret Getye Sidelel; [2020]
    Keywords : ;

    Abstract : Recently, the growing demand for high data rates in wireless communication, together with the scarcity of spectrum in existing microwave bands, has motivated the use of millimeter-wave (mmWave) bands for 5G and future wireless communications. Even though mmWaves are potential candidates for fulfilling this rising demand, they come along with their own drawbacks that need to be addressed. READ MORE

  2. 2. Communication Channel Measurement and Modeling for Inductive Wireless Power Transfer

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

    Author : Love Rosén; [2020]
    Keywords : Wireless power transfer; WPT; Qi Specification; Inductive coupling; Wireless charging; Channel modeling; Technology and Engineering;

    Abstract : Wireless Power Transfer (WPT) technology has experienced phenomenal success in the application of wireless charging of smartphones. With the Qi Specification becoming the dominant standard, wireless charging's convenience goes beyond cable-free charging to facilitate interoperability between chargers and devices from different vendors.

  3. 3. 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

  4. 4. 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

  5. 5. 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.
