  1. 11. Saturated planar laser-induced fluorescence using sinusoidal intensity modulation

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Klara Lozani Gerdhem; [2023]
    Nyckelord :fluorescence; fluorophore; LIF; PLIF; saturated LIF; saturated PLIF; structured light; Physics and Astronomy;

    Sammanfattning : Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. LÄS MER

  3. 12. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lucian Spitzner; [2023]

    Sammanfattning : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. LÄS MER

  4. 13. Validation of Quasi-Optical Antireflective Structures for Radar Lenses through Experimentation and Simulation

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Jeslin Preetha Sam Oliver; Simbarashe Tongai Makonese; [2023]
    Nyckelord :;

    Sammanfattning : This study focuses on designing, developing, and testing 3D-printed radar lenses with varying heights of Anti-Reflective (AR) structures (0.75mm, 1mm and 1.25mm). Radar lenses are essential to improve signal transmission and reception for radar systems. LÄS MER

  5. 14. Anomaly detection with machine learning methods at Forsmark

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Nyckelord :machine learning; nuclear power; nuclear power plant; anomaly detection; anomaly; data processing; data-driven; autoencoder; maskininlärning; kärnkraft; kärnkraftverk; Forsmark; anomalidetektion; anomali; databehandling;

    Sammanfattning : Nuclear power plants are inherently complex systems. While the technology has been used to generate electrical power for many decades, process monitoring continuously evolves. There is always room for improvement in terms of maximizing the availability by reducing the risks of problems and errors. LÄS MER

  7. 15. Robust heart rate estimation from a smartphone camera

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Ammar Darwesh; Miran Harivandy; [2022]
    Nyckelord :HR calculation; PPG; Photoplethysmography; HR calculation in smartphone;

    Sammanfattning : When it comes to calculating physical activity, nowadays a wide variety of tools is at our disposal.The phones used daily incorporate functions that calculate, for example, the number of steps taken throughout the day. Using the tools to set personal goals or to review which physical properties deviate. LÄS MER
