  1. 11. Diagnostics of Intermittent Errors

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Niklas Lindborg; [2021]
    Nyckelord :Intermittent errors; diagnostics; knowledge gap; fault isolation; Intermittenta fel; diagnostik; kunskapslucka; felisolering;

    Sammanfattning : Intermittent faults/errors are infamous for being among the most challenging errors to diagnose. It is estimated that more than 80% of the total number of errors in real systems are intermittent errors. Previous research on intermittent errors suggests that they are the prelude to permanent faults. LÄS MER

  3. 12. Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

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

    Författare :Sergio Steven Gutierrez; [2020]
    Nyckelord :QAM; NLIN; NLPN; Machine Learning; Coherent Optical Communication; Nonlinear Noise Compensation; Physics and Astronomy; Technology and Engineering;

    Sammanfattning : In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. LÄS MER

  4. 13. Advanced Ethernet Clock Synchronization based on Round Trip Time Protocol

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

    Författare :Granville Manvel Goes; [2020]
    Nyckelord :Networks; Ethernet; Clock synchronization; Synchronization error; Precision Time Protocol PTP ; Round Trip Time RTT protocol; Nätverk; Ehternet; Klocksynkronisering; Synkroniseringsfel; Precision Time Protocol PTP ; Round Trip Time RTT protocol;

    Sammanfattning : In this master thesis project, a new protocol called the Round Trip Time (RTT) protocol is implemented and verified. It helps determine the Ethernet clock frequency offset between two communicating nodes. The detection of this offset between nodes is a way to reduce the clock synchronization error. LÄS MER

  5. 14. Sensor fusion and fault diagnosticsin non-linear dynamical systems.

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

    Författare :Albin Nilsson; [2020]
    Nyckelord :Fault detection and isolation; FDI; sensor fusion; nonlinear; four wheel drive; vehicle; kinematics; kalman filter; KF; EKF; parity relations;

    Sammanfattning : Sensors are highly essential components in most modern control systems and are used in increasingly complex ways to improve system precision and reliability. Since they are generally susceptible to faults it is common to perform on-line fault diagnostics on sensor data to verify nominal behavior. LÄS MER

  7. 15. Time Synchronization for Full-Duplex Communications

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

    Författare :Ziyu Liu; Aamer Al-Hamwi; [2019]
    Nyckelord :Time Synchronization; In-band full-duplex; self-interference cancellation; Technology and Engineering;

    Sammanfattning : In-band full-duplex has emerged as an attractive solution for significantly enhancing the throughput of wireless communication systems by doubling the spectrum efficiency compared to conventional half-duplex systems. However, the existence of self-interference is a significant barrier to operate full-duplex systems. LÄS MER
