  1. 1. Audio Anomaly Detection in Cars

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Asma Hussein; [2023-09-11]
    Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

    Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

  3. 2. Fault diagnosis of a variable pole-phase motor

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

    Författare :Claes Henriksson; [2023]
    Nyckelord :Multiphase machine; variable pole-phase machine; fault diagnosis; switch fault; phase fault; harmonic plane decomposition; wound independently controlled stator coil machine; Multifasmaskin; variabel polfasmaskin; feldiagnosticering; brytarfel; fasfel; harmonic plane decomposition; WICSC-maskin;

    Sammanfattning : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. LÄS MER

  4. 3. Fault Tolerant Stabilizability in Multihop Control Networks

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

    Författare :Rana Faheem Iftikhar; [2023]
    Nyckelord :wireless networked control systems; Fault detection and isolation; Multihop control networks; WirelessHART; IT security; relay nodes failure; Design Wireless sensor network;

    Sammanfattning : The integration of control systems with wireless communication networks has gainedsignificant popularity, leading to the emergence of wireless networked control systems(WNCS). WNCS comprises wireless devices such as sensors, actuators, andcontrollers that work together to ensure system stabilizability. LÄS MER

  5. 4. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid

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

    Författare :Ili Atalla; [2023]
    Nyckelord :;

    Sammanfattning : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. LÄS MER

  7. 5. Fault Isolation and Identification in Autonomous Hauler Steering System

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Tobias Nyberg; Eric Lundell; [2022]
    Nyckelord :Data-driven fault detection; neural networks; Feed-Forward; Long Short-Term Memory; Hydraulics; Hauler;

    Sammanfattning : During the past years an increased focus on the development of autonomous solutions has resulted in driverless vehicles being used in numerous industries. Volvo Construction Equipment is currently developing the TA15, an autonomous hauler part of a larger transport solution. LÄS MER
