  1. 1. Fault Isolation in Distributed Embedded Systems

    Författare :Jonas Biteus; Erik Frisk; Jan Eric Larsson; Linköpings universitet; []
    Nyckelord :Fault diagnosis; Fault isolation; Distributed diagnosis; Embedded systems; Fault tree analysis.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. LÄS MER

  3. 2. Technical Language Supervision for Intelligent Fault Diagnosis

    Författare :Karl Löwenmark; Fredrik Sandin; Olga Fink; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Technical Language Processing; Natural Language Processing; Intelligent Fault Diagnosis; Natural Language Supervision; Condition Monitoring; Maskininlärning; Machine Learning;

    Sammanfattning : Condition Monitoring (CM) is widely used in industry to meet sustainability, safety, and equipment efficiency requirements. Intelligent Fault Diagnosis (IFD) research focuses on automating CM data analysis tasks, to detect and prevent machine faults, and provide decision support. LÄS MER

  4. 3. Residual Generation Methods for Fault Diagnosis with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

    Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

  5. 4. Towards Effective Fault Prevention : An Empirical Study in Software Engineering

    Författare :Niclas Ohlsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Quality improvement in terms of lower costs, shorter development times and increased reliability are not only important to most organisations, but also demanded by the customers. This thesis aims at providing a better understanding of which factors affect the number of faults introduced in different development phases and how this knowledge can be used to improve the development of large-scale software: In particular, models that enable identification of fault-prone modules are desirable.

  7. 5. Residual generation for fault diagnosis

    Författare :Erik Frisk; Lars Nielsen; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective when supervising technical processes is to alarm an operator when a fault is detected and also identify one, or possibly a set of components, that may have been the cause of the alarm. Diagnosis is an expansive subject, partly due to the fact that nowadays, more applications have more embedded computing power and more available sensors than before. LÄS MER
