1. 26. 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. 27. Validation of the attitude control of KNATTE with flexible appendages

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

   Author : Christoffer Johansson; [2022]
   Keywords : KNATTE; flexible appendages; control; SMC; LQG; PWM; PWPF;

   Abstract : The effect of flexible panels on a spacecraft during attitude movement may induce problems if not correctly accounted for in the control system for the spacecraft. The aim of this thesis is to find and evaluate, control algorithms that could be suitable for the Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) with two flexible mock-up solar panels during an attitude movement of 20 degrees.

4. 28. Investigating the use of Semiconductor Nanowires for Neural Networks

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Alfredo Serafini; [2022]
   Keywords : FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

   Abstract : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. READ MORE

5. 29. Design of a Future Residential DC Microgrid

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

   Author : Viktor Andersson; Max Gugolz; [2022]
   Keywords : Grid control; grid converter; DC microgrid; buck-boost; PV; MPPT; P O; ESS; SOC;

   Abstract : In the search for environmentally friendly methods to implement renewable energy in the power system residential microgrids have been proposed and proven. The direct current (DC) microgrid topology is a promising implementation of a microgrid system due to the increasing amount of DC-operated loads and production units expected in the near future.

6. 30. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

   University essay from Lunds universitet/Kemiska institutionen

   Author : Simone Facchini; [2022]
   Keywords : organic chemistry; membranes; isatin; polymers; Chemistry;

   Abstract : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. READ MORE
