1. 1. Wireless wave propagation in city street canyons

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Andrés Felipe Garcia Albarracin; [2017]
   Nyckelord :Channel modeling; Channel sounding; Local scattering function; Ray tracing.; Technology and Engineering;

   Sammanfattning : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.

3. 2. A durable mooring system for a winch-based wave energy converter

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Mingming Wang; [2017]
   Nyckelord :wave energy converter; winch; fatigue calculations; Vågomvandlare; vinsch; utmattningsberäkningar;

   Sammanfattning : This project has dealt with the developing a new technology for a renewable energy source, the wave energy, which is considered as one of the renewable resources with a potential to contribute to an energy production corresponding to about 10% of the world’s energy consumption nowadays. A point absorber concept that is using a Power Take-off (PTO) unit converts the sea surface wave motion into electricity thanks to a buoy at the sea surface which is moved by the waves. LÄS MER
