  1. 1. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    University dissertation from Stockholm : KTH

    Author : Oscar Flärdh; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. READ MORE

  2. 2. Multistage gearboxes vibration based quality control

    University dissertation from Stockholm : KTH

    Author : Johan Wändell; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering physics Acoustics; TEKNIKVETENSKAP Teknisk fysik Akustik;

    Abstract : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated.A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. READ MORE
