  2. 2. 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. 3. Integrated and Probabilistic Risk Analysis of Drinking Water Systems

    Författare :Andreas Lindhe; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; water safety plan; customer minutes lost; probabilistic; fault tree analysis; risk analysis; risk; integrated; drinking water system; hazard; uncertainty;

    Sammanfattning : Drinking water supply is an essential public function but is at the same time exposed to risks. Since a totally risk-free society is not attainable, risks need to be managed efficiently to achieve an acceptable level of risk. LÄS MER
