1. 11. Modulation of the optical properties of quantum dots by surface acoustic waves

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Tanguy Schetelat; [2023]
   Nyckelord :Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

   Sammanfattning : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. LÄS MER

3. 12. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Alexandros Bampis; [2023]
   Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

   Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

4. 13. DATA VISUALIZATION LITERACY Teachers’ considerations on Professional Learning in a Science Centre

   Master-uppsats, Göteborgs universitet/Institutionen för pedagogik, kommunikation och lärande

   Författare :Ana Gabriela Santos Guzmán; [2022-11-18]
   Nyckelord :Data Visualization; Teacher Professional Learning;

   Sammanfattning : Purpose: The overall aim of this study is to explore in-service teachers’ considerations regarding data visualization (DV) for their teaching practice and how a DV exhibition in a science centre can support their professional learning (PL) on this field. Approach: The overarching approach that was chosen for analysing data from this study is that of PL. LÄS MER

5. 14. Exchanging Bilateral Investment Treaties and Investor-State Dispute Settlement for the Acquis Communautaire : A three-stage analysis of the effects for investors, the level of investment protection and for the flow of Foreign Direct Investment on the internal market

   Uppsats för yrkesexamina på avancerad nivå, Stockholms universitet/Juridiska institutionen

   Författare :Carl Oscarsson; [2022]
   Nyckelord :;

   Sammanfattning : Through the judgements of Achmea and PL Holdings, the Court of Justice of the European Union (CJEU) has prohibited the use of Investor-State Dispute Settlement (ISDS) as well as the enforcement of any awards stemming from such procedures within the European Union (EU). This means that investors on the internal market can no longer enjoy the protection which was awarded to them by the protection standards inherent in the Bilateral Investment Treaties (BITs) which were previously relied upon by investors in the Member States (MS), and which provided for the possibility of ISDS.

7. 15. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Longgang Su; [2022]
   Nyckelord :Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

   Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER
