  1. 1. Processing of the 1992, 1994 and 1997 Campaigns in the Northen GPS Deformation Traverse

    Författare :Jonas Ågren; Lars Sjöberg; KTH; []
    Nyckelord :;

    Sammanfattning : The Northern GPS Deformation Traverse was established to detect movements at two major shear zones now active in northern Sweden, namely the NW trending Bothnian-Senja zone and the N trending Bothnian-Seiland zone. So far three GPS campaigns have been observed the processing of these three campaigns, and to investigate and compare different processing and analysis strategies. LÄS MER

  3. 2. Regional Geoid Determination Methods for the Era of Satellite Gravimetry : Numerical Investigations Using Synthetic Earth Gravity Models

    Författare :Jonas Ågren; Lars E. Sjöberg; Zdenek Martince; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; geoid determination; GOCE; synthetic earth gravity models; kernel modification; downward continuation; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : It is the purpose of this thesis to investigate different regional geoid determination methods with respect to their feasibility for use with a future GOCE satellite-only Earth Gravity Model (EGM). This includes investigations of various techniques, which involve different approximations, as well as the expected accuracy. LÄS MER

  4. 3. Distribution and Differences : Stratification and the System of Reproduction in a Swedish Peasant Community 1620-1820

    Författare :Jonas Lindström; Maria Ågren; Jan Lindegren; Carl-Johan Gadd; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Peasant; stratification; inequality; reproduction; resources; distribution; social mobility; household; family; community; landholding; principles; conditions; social structure; feudalism; early modern period; Björskog; Sweden; agrarian history; social history; History; Historia;

    Sammanfattning : This dissertation examines the character, conditions and change of peasant stratification in early modern Sweden. Wherever and whenever one looks, one finds that resources were unevenly spread among peasant households. In the literature, there are different, and conflicting, views compatible with this finding.

  5. 4. 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

  7. 5. Vårt fredliga samhälle : ”Lösdriveri” och försvarslöshet i Sverige under 1830-talet

    Författare :Theresa Johnsson; Maria Ågren; Jonas Lindström; Frans Lundgren; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; vagrancy; labour laws; compulsory service; labouring poor; policing; jails; begging; settlement; belonging; Romani people; Sweden; 19th century; internal passports; Historia; History;

    Sammanfattning : Between 1664 and 1885 labour in Sweden was regulated by compulsory-service statutes. Able-bodied but idle persons could be compelled to submit to em­ployment as a servant. LÄS MER
