1. 11. Design of a grating lobe mitigated antenna array architecture integrated with low loss PCB filtering structures

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

   Author : Eduardo Salvador Lopez; [2023]
   Keywords : Band-pass filters; Beam forming networks; Irregular subarrays; Particle Swarm Optimization; PCB; Penrose tessellation; Planar phased arrays; Quantization lobes; Scanning; Suspended stripline; Bandpassfilter; lobformning; matningsnätverk; Irreguljära gruppantenner; Particle Swarm Optimization; PCB; Penrose tessellation; Plana fasade gruppantenner; sidlober; Utstyrningsvinkel; Suspended stripline;

   Abstract : Massive multiple input multiple output - MIMO systems are a reality and modern communication systems rely upon this technology to cope with the increasing need for capacity and network usage. Antenna arrays are at the heart of the of the massive-MIMO system and are the enabling technology. READ MORE

3. 12. Designing intermediate community use during Brownfield phytoremediation in the post-industrial urban redevelopment project : a Case Study in Nyhamnen, Malmö

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Rie Chimura; [2023]
   Keywords : applicability analysis of phytoremediation; brownfield; intermediate community use; landscape architecture; post-industrial city of Malmö; sense of place;

   Abstract : Malmö, once flourished with industries, has been transitioning since its decline in the 1980s. The redevelopment of Nyhamnen, one of the post-industrial areas, started in 2018 to accommodate the expected increasing population until 2050. The City of Malmö focuses on redeveloping within instead of expanding the city. READ MORE

4. 13. Investigation of Antenna Radomes in Low Earth Orbits

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Mathias Manohar Gren; [2023]
   Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

   Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

5. 14. 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

6. 15. “Breaths of Joburg” – One Play, Multiple Perceptions : A Johannesburg Literary Site-Specific Theatre Pilot Project

   University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Author : Kerstin Tschernigg; [2023]
   Keywords : Communication; Communication for Development; South Africa; Johannesburg; Breaths of Joburg; Participatory Theatre; Perception Study;

   Abstract : This thesis examines the perception of the city of Johannesburg through a participatory theatre pilot project titled “Breaths of Joburg”. It looks at how different stakeholders, such as the performance director, professional and student actors, as well as the writers who inspired the texts used as a basis for the theatre, the live audience as well as the social media audience perceived Johannesburg and whether their perceptions changed after experiencing the play.
