  1. 21. 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

  3. 22. Harmonic Filters For Electronic Drive Systems Targeting Aircraft Applications

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Emelie Berglund; [2023]
    Nyckelord :Active Cancellation Filter; BLDC;

    Sammanfattning : Climate change pressures fossil-driven vehicles into electrification to sustain a healthy planet and environment for its inhabitants. Air traffic contributes to the ongoing climate crisis, and electric aircraft is taking its toll on the avionics market. LÄS MER

  4. 23. Performance Ratio as a Metric in Swedish PV Park Procurements

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

    Författare :Amanda Nilsson; Nora Orrenius; [2023]
    Nyckelord :Solar parks; key performance indicator; performance ratio; yield; solar park procurement; stakeholder analysis.; Solcellspark; nyckeltal; performance ratio; yield; solparksupphandling; intressentanalys;

    Sammanfattning : When procuring a solar PV park in Sweden there are many stakeholders involved. As of today, the metric called performance ratio (PR) is often used to guarantee the park’s performance. Nonetheless, comprehending and evaluating PR can be challenging due to its inherent complexity. LÄS MER

  5. 24. Development of a High Current Charger for Small Electric Boat Commuting

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