  1. 1. Track Before Detect in Active Sonar Systems

    University essay from Uppsala universitet/Signaler och system

    Author : Johnny Ljung; [2021]
    Keywords : signal processing; active sonar systems; track-before-detect; target tracking; reverberation; signalbehandling; aktiva sonarsystem; spårning innan detektion; målspårning; reverberation;

    Abstract : Detection of an underwater target with active sonar in shallow waters such as the Baltic sea is a big challenge. This since the sound beams from the sonar will be reflected on the surfaces, sea surface and sea bottom, and the water volume itself which generates reverberation. READ MORE

  3. 2. Implementation of adaptive filtering algorithms for noise cancellation

    University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Author : Tanja Lampl; [2020]
    Keywords : ;

    Abstract : This paper deals with the implementation and performance evaluation of adaptive filtering algorithms for noise cancellation without reference signal. Noise cancellation is a technique of estimating a desired signal from a noise-corrupted observation. READ MORE

  4. 3. Predictive Maintenance of DC Capacitors in STATCOMs

    University essay from

    Author : Rasmus Söderström; [2020]
    Keywords : Predictive Maintenance; STATCOM;

    Abstract : To further improve the reliability of STATCOM solutions a predictive maintenance system can give the user valuable readings of capacitor health an online and non-invasive, and especially readings of individual capacitors. This allows the user to replace individual deteriorating capacitor links in an MMC configuration before triggering any safety system. READ MORE

  5. 4. Signal-filtration methodology for estimation of fuel level

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Alexander Örneskans; [2018]
    Keywords : fuel level estimation; fuel level prediction;

    Abstract : Knowing how much fuel there is in a car is important for a predictable driving experience. Such knowledge will dictate how a person drives, when to refuel and how long they can drive. However unprocessed fuel level signals are highly noisy and therefore misleading. READ MORE

  6. 5. Fingerprint Matching using Small Sensors

    University essay from Lunds universitet/Matematik LTH

    Author : Rikard Drugge; [2017]
    Keywords : SVM; S3VM; SMOTE; ADASYN; filter; noise; fingerprint; small sensor; machine learning; Mathematics and Statistics;

    Abstract : Fingerprint software is widely used in applications such as smartphones. There has to be some overlap between two fingerprint samples in order for them to be considered as belonging to the same finger. READ MORE
