    Författare :Monica Karlsson; Engelska; []
    Nyckelord :HUMANIORA; HUMANITIES; Engelska språk och litteratur ; English language and literature; error gravity; proper noun; identification frame; genericness; the zero article; ‘idiomatic’ prepositional use; ‘systematic’ prepositional use; ‘basic’ prepositional use; non-contiguous subject-verb construction; contiguous subject-verb construction; subject-verb concord; fossilisation; restructuring of information; automatisation; interlanguage; cognitive second language acquisition theory; U-curve development; regression; progression; developmental pattern; relative frequency; error score; potential error; developmental continuum; advanced learner; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik; Applied linguistics; foreign languages teaching; sociolinguistics; Tillämpad lingvistik; undervisning i främmande språk; sociolingvistik;

    Sammanfattning : This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. LÄS MER

  2. 2. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and Pseudo-Gravity Gradient Tensors

    Författare :Majid Beiki; Laust Pedersen; Mehrdad Bastani; Mark Pilkington; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Gravity gradient tensor; pseudo-gravity; magnetic field; eigenvector analysis; least squares algorithm; strike direction; source parameter estimation; analytic signal; Euler deconvolution; joint inversion; infinite dike model; geological contact model; Solid earth physics; Fasta jordens fysik; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

    Sammanfattning : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. LÄS MER

  3. 3. Satellite Radar Altimetry for Determination of Geoid Undulations and Gravity Anomalies

    Författare :Jonas P. Noréus; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resolution; water vapour; geodesy; geoid undulations; gravity anomalies; precision; kriging; satellite remote sensing; radar altimetry;

    Sammanfattning : The sea level changes both temporally (due to dynamic effects) and spatially (due to sea bottom topography and inhomogeneities in the Earth's crust). Satellite radar altimetry is a remote sensing technique which can be used for e.g. determination of the instantaneous and mean sea level, and gravity anomalies at sea. LÄS MER

  4. 4. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. An Isostatic Earth Crustal Model : and Its Applications

    Författare :Mohammad Bagherbandi; Lars E. Sjöberg; Martinec Zdeněk; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Crustal thickness; inverse isostatic problem; isostasy; isostatic compensation; Moho depth; Moho density contrast; downward continuation; Earth sciences; Geovetenskap;

    Sammanfattning :  The Mohorovičič discontinuity (Moho), which is the surface separating the Earth’s crust from the mantle, is of great interest among geoscientists. The Moho depth can be determined by seismic and gravimetric methods. LÄS MER
