  2. 1. Early and Cost-Effective Software Fault Detection : Measurement and Implementation in an Industrial Setting

    Author : Lars-Ola Damm; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software; faults; defects; early fault detection; software process improvement;

    Abstract : Avoidable rework consumes a large part of development projects, i.e. 20-80 percent depending on the maturity of the organization and the complexity of the products. High amounts of avoidable rework commonly occur when having many faults left to correct in late stages of a project. READ MORE

  5. 3. Diagnosability performance analysis of models and fault detectors

    Author : Daniel Jung; Erik Frisk; Mattias Krysander; Michael Hofbaur; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Fault isolation; FDI; Kullback-Leibler divergence; Engine misfire detection;

    Abstract : Model-based diagnosis compares observations from a system with predictions using a mathematical model to detect and isolate faulty components. Analyzing which faults that can be detected and isolated given the model gives useful information when designing a diagnosis system. READ MORE

  6. 4. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

    Author : Joachim Härsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

    Abstract : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. READ MORE

  7. 5. Big Data Analytics for Fault Detection and its Application in Maintenance

    Author : Liangwei Zhang; Ramin Karim; Janet Lin; Benoît Iung; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Big Data analytics; eMaintenance; fault detection; high-dimensional data; stream data mining; nonlinear data; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Big Data analytics has attracted intense interest recently for its attempt to extract information, knowledge and wisdom from Big Data. In industry, with the development of sensor technology and Information & Communication Technologies (ICT), reams of high-dimensional, streaming, and nonlinear data are being collected and curated to support decision-making.
