1. 16. Hybrid solar district heating: combinations of high and low temperature solar technologies : A case study of Swedish DH system

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Lucrezia Giorgio; [2021]
   Keywords : District heating; Solar assisted district heating; Hybrid solar system; Flat plate collector; Parabolic trough collector; Photovoltaic thermal collector.;

   Abstract : In Sweden, the residential and industrial energy demand is provided by a significant part of district heating. In a decarbonization plan to reduce the CO2 emissions, the integration of a large-scale solar system in the district heating can be a suitable option. READ MORE

3. 17. A gamma-ray study of a highly variable blazar : The Fermi-LAT analysis and the modeling of the FSRQ PKS 1510–089

   University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Author : Nadja Bollström; [2021]
   Keywords : active galactic nuclei; AGN; astrophysics; jet; PKS 1510-089; Fermi; external Compton model; gamma-rays;

   Abstract : The subject of this thesis is the analysis and modeling of the active galactic nucleus PKS 1510-089. The aim is to present a thorough background of active galactic nuclei combined with the analysis and modeling of a specific active galactic nucleus. The results will then be  linked to previous research and theories about active galactic nuclei. READ MORE

4. 18. Electromagnetic Phase Engineering With Metamaterials

   University essay from KTH/Tillämpad fysik

   Author : Olof Sjödin; [2021]
   Keywords : Applied Physics; Electromagnetism; Metamaterials; MIM; Plasmonics; FEM; Reflector design; Phase engineering; Tillämpad fysik; Elektromagnetism; Metamaterial; MIM; Plasmonics; FEM; Reflektor design; Fasdesign;

   Abstract : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. READ MORE

5. 19. Integration of solar thermal collectors in the dairy industry: A techno-economic assessment : A case study of Dubai

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Hassim Shah; [2021]
   Keywords : Solar thermal; parabolic trough collector; levelized cost of heat; integration schemes;

   Abstract : A predominant amount of energy needed in the industrial sector is in the form of heat. A significant number of industries in the world still relies on fossil fuels for meeting their heat requirements. READ MORE

6. 20. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Akila Wajirakumara; [2021]
   Keywords : ;

   Abstract : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.
