  4. 3. Performance Estimation of a 1D pulsed LiDAR : A Study of SiPM-Based LiDAR in Ambient Light

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Joel Rune; [2023]
    Nyckelord :LiDAR; SiPM; SPAD; Ambient light; LiDAR; Kisel-fotomultiplikator; SPAD; Bakgrundsljus;

    Sammanfattning : LiDAR is a remote sensing technology that uses a laser to map the surrounding environment. With its many applications, for example in autonomous vehicles, LiDAR is a growing field within technology and research. The silicon photomultiplier (SiPM) is a solid state device commonly used in the receiving system of a LiDAR. LÄS MER

  5. 4. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Joel Ekström; [2023]
    Nyckelord :Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Sammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER

  7. 5. Prolongation of shelf life of minimally processed spinach by combining vacuum impregnation and electric field treatments

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Sophia Leffler; [2022]
    Nyckelord :spinach; pulsed electric field; moderate electric field; reversible electroporation; vacuum impregnation; shelf life; metabolic activity; respiration; food engineering; Agriculture and Food Sciences;

    Sammanfattning : A continuous growth of the world population raises the importance of preserving food resources while maintaining their nutrient value. Leafy vegetables such as spinach are a food category which decay quickly, and a large amount ends up as food waste. LÄS MER
