1. 16. Increasing the Crossover Levels of Beams in Geodesic Luneburg Lens Antennas

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

   Author : Philip Arnberg; [2021]
   Keywords : Luneburg lens; geodesic lens; generalized Luneburg lens; crossover level and lens antennas.; Luneburg lins; geodetisk lins; generaliserad Luneburg lins; korsningsnivåer och linsantenner.;

   Abstract : The new and forthcoming generation of mobile networks intend to operate at considerably higher frequencies than the previous systems. This lift in frequency of operation alleviates today’s communication systems’ crowded bandwidth and allows for faster data rates than previously possible. READ MORE

3. 17. Hybrid Coupler for LMBA Input Match Using an Active Inductor

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Karthik Doddanna; [2021]
   Keywords : LMBA; gyrator-c; active inductor; hybrid coupler; TSMC 0.18um.;

   Abstract : With the increase in demand for compact and high data rate communication systems, there is a need for high efficiency with modulated signals (PAPR 5-10 dB) for base-station power amplifiers. One of the famous architectures used to achieve this is Doherty architecture. READ MORE

4. 18. Active- integrated aperture lens antenna

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

   Author : Jesus Ventas Muñoz de Lucas; [2021]
   Keywords : ;

   Abstract : Luneburg lens antennas are gaining popularity in new communication systems, as increasingly higher frequencies are being used. Broadband fully- metallic implementations of Luneburg lenses, such as Rinehart- Luneburg lenses, constitute simple, cheap and efficient beamformers. READ MORE

5. 19. Big Data usage in the Maritime industry : A Qualitative Study for the use of Port State Control (PSC) inspection data by shipping professionals

   University essay from Linnéuniversitetet/Institutionen för informatik (IK)

   Author : Dimitrios Ampatzidis; [2021]
   Keywords : Big Data; Data Analytics; Port State Control; Shipping; Maritime; Information Systems; Big Data characteristics; Big Data and Analytics value; Qualitative study; Interviews; Shipping professionals;

   Abstract : Vessels during their calls on ports is possible to have an inspection from the local Port State Control (PSC) authorities regarding their implementation of International Maritime Organization guidelines for safety and security. This qualitative study focuses on how shipping professionals understand and use Big Data in the PSC inspection databases, what characteristics they recognize these data should have, what value they attach to those big data, and how they use them to support the decision-making process within their organizations.

6. 20. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Oskar Evert Johansson; [2021]
   Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

   Abstract : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. READ MORE
