  1. 1. Occupancy detection and prediction with sensors and online machine learning : Case study of the Elmia exhibition building in Jönköping

    Master-uppsats, KTH/Byggvetenskap

    Författare :Allen Chen; [2022]
    Nyckelord :;

    Sammanfattning : Buildings account for approximately 40% of energy consumption in the EU, and despite drastic increasing measures for energy efficient operation, the net value of energy consumption is expected to continue increasing because ofincreasing urbanization.While there has been increasing work done on managing external loads such as adapting to unpredictable climates, the research on internal loading, such as occupants, is still nascent.

    Sammanfattning : Sandvik Coromant develops and produces tools used in machining. Chatteris a self-excited vibration in the machine or work piece that can occurduring machining and cause tool damage. New technologies develop thetools with accelerometers, data from the accelerometers can be used topredict tool damage. LÄS MER

  4. 3. Anomaly Detection in Streaming Data from a Sensor Network

    Master-uppsats, KTH/Matematisk statistik

    Författare :Egill Vignisson; [2019]
    Nyckelord :Anomaly Detection; Sequential Data; Semi-supervised Learning; Recurrent Neural Network; Applied Mathematics; Anomalidetektion; sekventiell data; halv-övervakad maskininlärning; återkommande neuralt nätverk; tillämpad matematik.;

    Sammanfattning : In this thesis, the use of unsupervised and semi-supervised machine learning techniques was analyzed as potential tools for anomaly detection in the sensor network that the electrical system in a Scania truck is comprised of. The experimentation was designed to analyse the need for both point and contextual anomaly detection in this setting. LÄS MER
