  3. 7. Makt och vanmakt i fadersväldet : Studentpolitik i Uppsala 1780–1850

    Författare :Johan Sjöberg; John Strömberg; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History; university history; students; political culture; youth; patriarchy; Historia; History subjects; Historieämnen; Historia; History;

    Sammanfattning : From the end of the 18th century, the view that youth had a political role to play spread among students in Europe. This view was directly opposed to the paternalistic authoritarian regimes governing the old universities like that at Uppsala, which had been organised as patriarchal corporations for some two hundred years.

    Sammanfattning : I denna avhandling studeras optimal återkopplad styrning av olinjära deskriptorsystem. Ett deskriptorsystem är en matematisk beskrivning som kan innehålla både differentialekvationer och algebraiska ekvationer. LÄS MER

  7. 10. Undifferenced GPS for Deformation Monitoring

    Författare :Johan Vium Andersson; Lars Sjöberg; Jonas Ågren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; Geoengineering; Geoteknik;

    Sammanfattning : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. LÄS MER
