  1. 1. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

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

    Författare :Olle Sundberg; Vincent Forsberg; [2023]
    Nyckelord :;

    Sammanfattning : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. LÄS MER

  3. 2. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Vilma Hurtigh Grabe; [2023]
    Nyckelord :bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Sammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER

  4. 3. Finite Element Simulation of Moisture Transport in Cellulose Insulation Material of Power Transformers

    Master-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Luc Villibord; [2023]
    Nyckelord :;

    Sammanfattning : Power Transformers are an important and complex part of the electrical transmission technology. One of the main producers of these transformers worldwide is Hitachi Energy, for which this work has been done. LÄS MER

  5. 4. 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

  7. 5. TEMPERATURE MODELLING OF GEAR MESH

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ahsan Kadevalappil Ajilan; [2023]
    Nyckelord :Helical gear; Power loss; MATLAB; ANSYS; Spiralväxel; Strömförlust; MATLAB; ANSYS;

    Sammanfattning : Temperature control is an essential aspect of gear design. Continuous research is going on to improve the efficiency of gear systems. Power losses or energy losses in these systems typically manifest themselves as increased temperatures and thus reducing the lifetime and overall performance of the system. LÄS MER
