  1. 21. Source and Channel Coding for Compressed Sensing and Control

    Författare :Amirpasha Shirazinia; Mikael Skoglund; Pier Luigi Dragotti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source coding; quantization; channel coding; compressed sensing; control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Rapid advances in sensor technologies have fueled massive torrents of data streaming across networks. Such large volume of information, indeed, restricts the operational performance of data processing, causing inefficiency in sensing, computation, communication and control. LÄS MER

  3. 22. Decoding the language of transmission among vector-pathogen-host

    Författare :Melika Hajkazemian; S. Noushin Emami; Richard Hopkins; Stockholms universitet; []

    Sammanfattning : Vector-borne diseases account for over 17 percent of all infectious diseases and lead to more than 700,000 mortalities annually. Importantly, there is a complex interaction between infectious organisms and their host. LÄS MER

  4. 23. On Tracing Flicker Sources and Classification of Voltage Disturbances

    Författare :Peter Axelberg; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transmission and distribution; digital signal processing; power quality monitoring; light flicker; power system disturbance; support vector machines; Medicinteknik; voltage dips;

    Sammanfattning : Developments in measurement technology, communication and data storage have resulted in measurement systems that produce large amount of data. Together with the long existing need for characterizing the performance of the power system this has resulted in demand for automatic and efficient information-extraction methods. LÄS MER

  5. 24. Passive Island Detection of Microgrid by Grid Forming Inverter

    Författare :Shoaib Salim Inamdar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microgrid; passive island detection; Grid forming; rotor angle deviation; non-detection zone; inertia; virtual synchronous machine; voltage vector shift.;

    Sammanfattning : The supply reliability of a local grid will be improved if the local grid is managed as a microgrid, with the ability to operate in island mode when the main grid is temporarily unavailable. This thesis focuses on microgrids powered by inverter-based resources (IBRs), one or several of which need to be equipped with grid forming (GFM) capability for establishing and controlling the voltage and frequency of the microgrid during island operation.

  7. 25. Grid-Connected Voltage Source Converter - Control Principles and Wind Energy Applications

    Författare :Jan Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind turbine; voltage source converter; voltage angle control; frequency response; vector current control; grid-connected; forced-commutated; measurements;

    Sammanfattning : The thesis focuses on a forced-commutated voltage source converter (VSC) connected to a grid in a wind energy application. The work consists of four parts. The first part addresses the type of electrical system which should be used in a wind turbine. LÄS MER
