1. 6. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

   University essay from

   Author : Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
   Keywords : Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

   Abstract : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. READ MORE

3. 7. Antenna Options for High Altitude IMT Base Stations (HIBS) in Cellular Networks

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Harald Magnusson; [2022]
   Keywords : High altitude IMT Base Station HIBS ; High Altitude Platform Station HAPS ; Link Feasibility; Coverage Feasibility; Phased Array Antenna; Parabolic Reflector Antenna;

   Abstract : This thesis is the result of a collaboration between Ericsson AB and Luleå University of Technology. A feasibility study has been conducted to investigate antenna options for the HIBS access link. The study contains two parts. Firstly, a link budget investigating the gain required from the antenna.

4. 8. High-Level Simulator of Federation Orchestration

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Toon Keymeulen; [2022]
   Keywords : Technology and Engineering;

   Abstract : The development of a new wireless access infrastructure can introduce some exciting new applications that are impossible to deploy with the current generation communication infrastructure. Therefore the REINDEER project presents a new distributed cell-free network infrastructure called RW, that creates favourable propagation and antenna array interaction. READ MORE

5. 9. Effects on the precision of a brain-computer interface when reducing the number of neural recordings used as input

   University essay from KTH/Datavetenskap

   Author : Oscar Knowles; Carl Peterson; [2022]
   Keywords : ;

   Abstract : A brain-computer interface (BCI) is a technology where electric activity from the brain is interpreted by a computer in order to perform a specific task. There exists various methods to record brain activity depending on if the recording devices are implanted under or over the scalp. READ MORE

6. 10. Dual-polarized fully-metallic Vivaldi antenna array in a triangular lattice

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

   Author : Omar Orgeira Alvarez; [2022]
   Keywords : Base station; Mobile communications; Phased arrays; Vivaldi antenna; Stripline; Basstation; Mobilkommunikation; Phased arrays; Vivaldi-antenn; Stripline;

   Abstract : New mobile communication generations need electromagnetic sensors capable of steering their high-directive beams towards the users. Conventional base stations use square lattice phased arrays to accomplish this task. These arrays are composed of a large number of radiating elements to achieve the required high directivity and scanning capabilities. READ MORE
