  4. 2. Failure diagnostics using support vector machine

    Author : Yuan Fuqing; Thomas Lindblad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Failure diagnostics is an important part of condition monitoring aiming to identify incipient failures in early stages. Accurate and efficient failure diagnostics can guarantee that the operator makes the correct maintenance decision, thereby reducing the maintenance costs and improving system availability. READ MORE

  5. 3. Machine learning-based diagnostics and observability in mobile networks

    Author : Tobias Sundqvist; Erik Elmroth; Monowar H. Bhuyan; Rolf Stadler; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; Root cause analysis; Observability; Machine learning; Radio Access Network; 5G; Computer Science; datalogi;

    Abstract : To meet the high-performance and reliability demands of 5G, the Radio Access Network (RAN) is moving to a cloud-native architecture. The new microservice architecture promises increased operational efficiency and a shorter time-to-market, but it also comes with a price. READ MORE

  6. 4. Intelligent fault diagnosis and predictive maintenance for a bearing ring grinder

    Author : Muhammad Ahmer; Pär Marklund; Fredrik Sandin; Kim Berglund; Martin Gustafsson; Peter Krajnik; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analysis; grinding machines; diagnostics; predictive maintenance; condition monitoring; intelligent fault diagnosis; Maskinelement; Machine Elements;

    Abstract : Predicting the failure of any structure is a difficult task in a mechanical system. However complicated and difficult the prediction might be, the first step is to know the actual condition of the system. READ MORE

  7. 5. Data-driven battery aging diagnostics and prognostics

    Author : Yizhou Zhang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; battery management system; remaining useful life; Lithium-ion batteries; machine learning.; state of health;

    Abstract : Lithium-ion (Li-ion) batteries play a pivotal role in transforming the transportation sector from heavily relying on fossil fuels to a low-carbon solution. But, as an electrochemical device, a battery will inevitably undergo irreversible degradation over time. READ MORE
