  1. 1. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework

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

    Author : Niklas Barth; [2023]
    Keywords : Unsupervised Learning; Multivariate Time Series; Graph Convolutional Neural Networks; Anomaly Detection; Industrial Control System; EtherCAT; Power Station; Electricity Grid;

    Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

  3. 2. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

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

    Author : Viktor Olsson; [2023]
    Keywords : Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Abstract : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. READ MORE

  4. 3. MODELING AND EVALUATING AN INTELLIGENT HEALTH MONITORING SYSTEM FOR ATRIAL FIBRILLATION DETECTION

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Petter Nordin; [2022]
    Keywords : ;

    Abstract : The heart disease Atrial Fibrillation (AFib) has increased worldwide in recent years. Untreated AFib can lead to cardiovascular complications such as stroke and heart failure. AFib is detected by physicians using Electrocardiogram (ECG). Since this disease can occur without symptoms for some patients, it can lead to late detection. READ MORE

  5. 4. The application of low-cost sensors in estimates of greenhouse gases : A field study at a wastewater treatment plant

    University essay from Linköpings universitet/Filosofiska fakulteten; Linköpings universitet/Tema Miljöförändring

    Author : Daniel Montecinos; Saga Magnusson; [2022]
    Keywords : Methane; Carbon dioxide; wastewater treatment; Low-cost sensor network; Measurement; Environmental monitoring;

    Abstract : Anthropogenic activity has caused increased concentrations of greenhouse gases (GHGs) in the atmosphere which has resulted in global warming gaining momentum. GHG emission estimates up to date are insufficient and in order to mitigate GHG emissions of anthropogenic origin fluxes of GHGs need to be mapped. READ MORE

  6. 5. Machine Learning-Based Data-Driven Traffic Flow Estimation from Mobile Data

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

    Author : Pei-Lun Hsu; [2021]
    Keywords : Intelligent transport systems; Traffic flow estimation; Machine learning; Artificial neural network; Mobile data; Intelligenta transportsystem; Estimering av trafikflöde; Maskininlärning; Artificiellt neuronnät; Mobila data;

    Abstract : Comprehensive information on traffic flow is essential for vehicular emission monitoring and traffic control. However, such information is not observable everywhere and anytime on the road because of high installation costs and malfunctions of stationary sensors. READ MORE
