  1. 1. Detection of Long Term Vibration Deviations in GasTurbine Monitoring Data

    University essay from Linköpings universitet/Fordonssystem

    Author : Johan Hansson; [2020]
    Keywords : Machine Learning; Vibrations;

    Abstract : Condition based monitoring is today essential for any machine manufacturer tobe able to detect and predict faults in their machine fleet. This reduces the maintenancecost and also reduces machine downtime. READ MORE

  2. 2. Implementation of improved fat standardization using statistical process control

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Lovisa Bjenning; [2019]
    Keywords : Milk; Whole milk; Semi-skimmed milk; Fat content; Statistical process control; MilkoScan FT2;

    Abstract : The aim of this project was to apply statistical process control (SPC) and measure the variation of fat content in milk in order to improve the standardization, so that the fat content does not change more than 0.03 percentage units from target. Recommendations of how to adjust the standardization should also be developed. READ MORE

  5. 5. 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
