  1. 1. Transfer time over RIST protocol to become independent of NTP

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

    Författare :Simon Malmström Berghem; [2023]
    Nyckelord :RIST; time synchronization; NTP; video transmission;

    Sammanfattning : The reliable internet stream transport (RIST) protocol is used for streaming video over the internet and requires time synchronisation to ensure that each frame is played out at the correct time. One method to ensure time synchronisation today in RIST productions is by utilizing the network time protocol (NTP). LÄS MER

  3. 2. GNSS Safety and Handling

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Axel Björklund; [2022]
    Nyckelord :Navigation; GNSS; GPS; Galileo; OSNMA; TESLA protocol; SHA-256; jamming; spoofing; SDR; GPS-SDR-SIM; Smart Tachograph; dead reckoning; U-blox; Volvo Group; Volvo FH;

    Sammanfattning : Satellite navigation (such as GPS) has become widely successful and is used by billions of users daily. Accuratepositioning and timing has a wide range of applications and is increasingly being integrated in safety criticalsystems such as autonomous operations, traffic management, navigation for airplanes and other vehicles.

  4. 3. Machine Learning for Radar in Health Applications : Using machine learning with multiple radars to enhance fall detection

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Kristoffer Raskov; Oliver Christiansson; [2022]
    Nyckelord :Machine learning; RNN; Bi-LSTM; radar; sensor fusion; HAR; fall detection; healthcare monitoring; Maskininlärning; RNN; Bi-LSTM; radar; sensor fusion; HAR; falldetektering; hälsoövervakning;

    Sammanfattning : Two mm-wave frequency modulated continuous wave (FMCW) radars were combined with a recurrent neural network (RNN) to perform fall detection. The purpose was to find methods to implement a multi-radar setup for healthcare monitoring and to study the resulting models’ resilience to interference and other obstacles, such as re-arranging the radars in the room.

  5. 4. Evaluation of how clock synchronisation protocols affects inter-sender synchronisation of live continuous multimedia

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Emil Nilsson; [2018]
    Nyckelord :;

    Sammanfattning : There exists several inter-sender synchronisation algorithms today, some of these requires globally synchronised clocks. Exactly how the clocks are going to be synchronised are generally not mentioned. This thesis aims to investigate how the choice of clock synchronising protocol affects these kinds of synchronisation algorithms. LÄS MER

  7. 5. Synkronisera grafik till flera skärmar för sportevenemang

    M1-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Hugo Moritz; William Hellgren; [2018]
    Nyckelord :;

    Sammanfattning : Multi-screen video playback is often used for sports events. It is important that the graphics are visualized synchronized. The thesis investigates a solution for synchronizing video to multiple devices through a central computer. LÄS MER
