  1. 6. Detection of friction variations in bolted joints during tightening

    University essay from KTH/Reglerteknik

    Author : Ioannis Tilaveridis; [2017]
    Keywords : ;

    Abstract : Tightening describes the process of rotating a screw with the purpose of binding two surfaces together. It is widely applied in the assembly process of structures, where bolted joints are used to connect the different parts with each other, e.g. robot arms, vehicles, aircrafts. READ MORE

  3. 7. A Multivariate Data Stream Anomaly Detection Framework

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Jiakun Jin; [2016]
    Keywords : Multivariate; Stream anomaly detection; PYISC; SVM; LOF; DDM; CUSUM; FCWM; Multivariat; ström anomali detektion; PYISC; SVM; LOF; DDM; CUSUM; FCWM;

    Abstract : High speed stream anomaly detection is an important technology used in many industry applications such as monitoring system health, detecting financial fraud, monitoring customer's unusual behavior and so on. In those scenarios multivariate data arrives in high speed, and needs to be calculated in real-time. READ MORE

  4. 8. PRAAG Algorithm in Anomaly Detection

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Dongyang Zhang; [2016]
    Keywords : Anomaly detection; Collective Anomaly; Algorithm; Data Mining 1; Detektion av avvikelser; kollektiv avvikelse; algorithm; datautvinning;

    Abstract : Anomaly detection has been one of the most important applications of datamining, widely applied in industries like financial, medical,telecommunication, even manufacturing. In many scenarios, data are in theform of streaming in a large amount, so it is preferred to analyze the datawithout storing all of them. READ MORE

  5. 9. Estimation of Ship Properties for Energy Efficient Automation

    University essay from Linköpings universitet/Reglerteknik

    Author : Lucas Nilsson; [2016]
    Keywords : System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

    Abstract : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. READ MORE

  6. 10. Sensor Validation Using Linear Parametric Models, Artificial Neural Networks and CUSUM

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Gustaf Norman; [2015]
    Keywords : Sensor Validation; Linear Parametric Models; Artificial Neural Networks; ANN; Fault Detection; CUSUM;

    Abstract : Siemens gas turbines are monitored and controlled by a large number of sensors and actuators. Process information is stored in a database and used for offline calculations and analyses. Before storing the sensor readings, a compression algorithm checks the signal and skips the values that explain no significant change. READ MORE
