  3. 22. Fault diagnosis of axlebox roller bearings of high speed rail vehicles based on empirical mode decomposition and machine learning

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : JOSUA KEHLENBACH; [2021]
    Keywords : Condition monitoring; axlebox bearings; machine learning; data fusion; Nyckelord: tillståndsövervakning; axelboxlager; maskininlärning; datafusion;

    Abstract : Axlebox bearings are one of the most critical components of a rail vehicle with regard to safety. An axlebox bearing that breaks during operation can be dangerous for the passengers and expensive for the operator. In-service failure of axlebox bearings has been the cause of many catastrophic accidents. READ MORE

  4. 23. Identifying New Fault Types Using Transformer Embeddings

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mikael Karlsson; [2021]
    Keywords : Transformer Models; Clustering; Embeddings; Deep Learning; Fault Identification; Transformatorbaserade modeller; Klustering; Djupinlärning; Felidentifiering;

    Abstract : Continuous integration/delivery and deployment consist of many automated tests, some of which may fail leading to faulty software. Similar faults may occur in different stages of the software production lifecycle and it is necessary to identify similar faults and cluster them into fault types in order to minimize troubleshooting time.

  5. 24. Data mining techniques for modeling the operating behaviors of smart building control valve systems

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Amirmohammad Eghbalian; [2020]
    Keywords : Machine learning; Data mining; Outlier detection; Time-series; HVAC R;

    Abstract : Background. One of the challenges about smart control valves system is processing and analyzing sensors data to extract useful information. These types of information can be used to detect the deviating behaviors which can be an indication of faults and issues in the system. READ MORE

  6. 25. A Machine Learning-Based Approach for Fault Detection of Railway Track and its Components

    University essay from Luleå tekniska universitet/Drift, underhåll och akustik

    Author : Johnny Asber; [2020]
    Keywords : Condition Based Maintenance in Railway; Machine Learning; Deep Learning; ResNet-50;

    Abstract : The hard equation of railway safety versus the high commercial profits can only be achieved through the use of new inspection methods supported by modern technologies. The track and its components can have different types of troubles, such as rail surface defects, broken sleepers, missing fasteners, and irregular ballast levels. READ MORE
