  1. 1. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

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

    Author : Zhenyu Li; [2023]
    Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

    Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

    Abstract : In recent years, unmanned aerial vehicles (UAV), also called drones, have experienced a rapid increase, which leads to the concern of illegal use of them. Passive RF is one of the effective ways to detect drones by receiving drones’ communication signals. READ MORE

  5. 4. Analysis of AEP prediction against production data of commercial wind turbines in Sweden

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Aromal Sugathan; Sean Gregory; [2021]
    Keywords : Energy assessment; validation; wind power; Sweden; P50; AEP; WCP;

    Abstract : Based on data from 2083 wind turbines installed in Sweden since 1988, the annual energy production (AEP) predictions considered at the project planning phases of the wind turbines in Sweden have been compared to the wind-index-corrected production data. The production data and the predicted AEP data are taken from Vindstat, a database that collects information directly from wind turbine owners in Sweden. READ MORE
