  1. 6. Improving polarizing neutron optics by introducing 11B4C as interlayers

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Martin Falk; [2023]
    Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

    Abstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE

  2. 7. In situ X-ray diffraction studies of vertically aligned CsPbBr3 nanowire arrays

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Jesper Larsson; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.

  3. 8. Development of a validation shape sensing algorithm in Python with predictive and automatedanalysis

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Carlos Castellanos; [2021]
    Keywords : python; FBG; deflection; wavelength; machine learning; forecast;

    Abstract : Difficulties with wind turbines can arise during operation due to externalforces provoked by the wind. Calculating the deflection of the blades can beused to give break points for maintenance, design and/or monitoring purposes. READ MORE

  4. 9. Simultaneous measurement and discrimination of temperature and strain in distributed fiber optical systems with fiber Bragg gratings

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Helene Alexandra Mastrothanasis; [2021]
    Keywords : ;

    Abstract :  This master thesis deals with simultaneous measurement and discrimination of temperature and strain using fiber Bragg gratings(FBGs). Saab Avionics is seeking for a further development of the overheat detection system that gives a warning when a heat leakage is detected. READ MORE

  5. 10. Evaluation of Strain and Temperature Measurements with Fiber Bragg Grating for Loss Verification and Heat Transfer of Ball Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik
