  1. 1. Parameter and State Estimation with Information-rich Signals

    Författare :Magnus Evestedt; Alexander Medvedev; Fredrik Gustafsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information-rich signals; audio; video; acoustic echo cancellation; steel production; LD-converter; Kalman filter; covariance windup; recursive parameter estimation; Automatic control; Reglerteknik;

    Sammanfattning : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. LÄS MER

  3. 2. Blind Adaptive Extraction of Impulsive Signatures from Sound and Vibration Signals

    Författare :Aziz Kubilay Ovacikli; Johan Carlson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The two questions in science ``why" and ``how" are hereby answered in the context of statistical signal processing applied to vibration analysis and ultrasonic testing for fault detection and characterization in critical materials such as rolling bearings and thin layered media. Both materials are of interest in industrial processes. LÄS MER
