  1. 6. Transient Waveform Clustering : Developing efficient data analytics toolchains applying unsupervised machine learning techniques on power quality events

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Albert Varghese Rajan; [2021]
    Keywords : HVDC; Power Quality; Machine Learning; Autoencoder; Clustering; Monitoring and analytics;

    Abstract : High Voltage Direct Current (HVDC) transmission systems appropriate for bulk power transfer to meet increasing power demands and ideal for interconnecting power systems with distant renewable sources of energy without any chances of loss synchronism, efficiency, and reliability. The main obstacle is however connected with the DC grid protection where the timely diagnosis of faults is critical to prevent any rapid built-up leading to failure of the power electronic devices.

  4. 8. ON EVALUATING MACHINE LEARNING APPROACHES FOR EFFICIENT CLASSIFICATION OF TRAFFIC PATTERNS

    University essay from Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

    Author : Sai Srilakshmi Kanumuri; [2017]
    Keywords : machine learning; classification; traffic patterns; cellular mobile networks.;

    Abstract : Context. With the increased usage of mobile devices and internet, the cellular network traffic has increased tremendously. This increase in network traffic has led to increased occurrences of communication failures among the network nodes. READ MORE

  5. 9. Supervision of the Air Loop in the Columbus Module of the International Space Station

    University essay from Linköpings universitet/Fordonssystem

    Author : Jasper Germeys; [2016]
    Keywords : model based diagnosis; residual generation; structural analysis; causality; automated design;

    Abstract : Failure detection and isolation (FDI) is essential for reliable operations of complex autonomous systems or other systems where continuous observation or maintenance thereof is either very costly or for any other reason not easily accessible. Beneficial for the model based FDI is that there is no need for fault data to detect and isolate a fault in contrary to design by data clustering. READ MORE

  6. 10. Distributed Graph Clustering: Study of DiDiC and Some Simpler Forms

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Sahar Fallahtoori; [2015]
    Keywords : ;

    Abstract : The size of global electronic data in need of storage and retrieval is growing with an increasing rate. As a result of this growth, the development of technologies to process such data is a necessity. The data is developing in both complexity and connectivity, particularly for social networks. READ MORE
