1. 1. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Author : Louise Olausson; [2022]
   Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

   Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

3. 2. Simulation of a Battery Energy Storage System for Fast Frequency Reserve Support.

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Pathirage Dona Upekha Nimanthi Pathirage; [2022]
   Keywords : Energy Storage; Renewable Energy; Battery; Fast Frequency Reserve; Lithium-ion;

   Abstract : Electricity providers has a growing interest in moving towards Renewable Energy Sources (RES) for power generation due to their attractive features. This has caused phasing out of coal, oil and nuclear power plants which use large synchronous generators for power production. READ MORE

4. 3. Optimization of Kaplan turbines for frequency regulation in hybrid hydropower plants

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Keywords : E-commerce; Social Media Marketing Activities; Brand Image; Purchase Intention; Social Media.;

   Abstract : Background: Due to the digital era and a constant increase in social media usage, new ways to interact with customers can be done through adopting Social Media Marketing Activities (SMMA). The concept SMMA is constituted by the five dimensions ‘Entertainment’, ‘Interaction’, ‘Trendiness’, ‘Customization’ and ‘Word-of-mouth’. READ MORE

6. 5. 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.
