  3. 12. Developing a Cost Model For Combined Offshore Farms : The Advantages of Co-Located Wind and Wave Energy

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eva Blech; [2023]
    Keywords : Wave Energy; Floating Offshore Wind; Co-located Wind-Wave Farm; Levelized Cost of Energy; Multi-Source Offshore Farm; Vågenergi; flytande havsbaserad vindkraft; samlokaliserad vind- och vågpark; nivellerad energikostnad; havsbaserad park med flera källor;

    Abstract : Previous research has displayed that multi-source farms provide an opportunity to reduce the cost of energy and improve the energy output quality. This thesis assesses the cost competitiveness of co-located wind-wave farms, specifically floating offshore wind (FLOW) turbines and CorPower’s wave energy converters (WEC). READ MORE

  4. 13. Investigating the impact of physical layer transmission for Bluetooth LE Audio

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Kevin Arponen; Axel Björkman; [2023]
    Keywords : Bluetooth Low Energy; Energy consumption; LC3; LE Audio; Physical Layer; Throughput; Wireless audio streaming; Wireless communication;

    Abstract : Bluetooth Low Energy (BLE) is a widely used low-energy version of Bluetooth’swireless protocol. To meet increasing requirements of modern wireless audio devices,Bluetooth LE Audio was released with its new Low Complexity CommunicationsCodec (LC3) being much more data efficient than its predecessor Low Complexity SubBand Coding.

  5. 14. Laboratory starlight simulator for future space-based heterodyne interferometry

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : William Karlsson; [2023]
    Keywords : Angular resolution; Astronomy; Coherence length; Digital delay lines; Fiber optical circuit; Heterodyne interferometry; Interference; Laboratory starlight simulator; NIR light Near-Infrared ; Optical path differences; Space exploration; Starlight; Testbed environment;

    Abstract : In astronomy, interferometry by ground-based telescopes offers the greatest angular resolution. However, the Earth´s atmosphere distorts the incident wavefront from a celestial object, leading to blurring and signal loss. It also restricts the transmission of specific wavelengths within the electromagnetic spectrum. READ MORE

  6. 15. Experimental studies of radiation damage in uranium nitride

    University essay from KTH/Fysik

    Author : Maria Giamouridou; [2023]
    Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE
