  1. 1. 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; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    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

  2. 2. Gravity Illustrated. Spacetime Edition

    Författare :Rickard Jonsson; Chalmers University of Technology; []
    Nyckelord :embeddings; pedagogical techniques; curved spacetime; optical geometry; gyroscope precession; inertial forces;

    Sammanfattning : This thesis deals with essentially four different topics within general relativity: pedagogical techniques for illustrating curved spacetime, inertial forces, gyroscope precession and optical geometry. Concerning the pedagogical techniques, I investigate two distinctly different methods, the dual and the absolute method. LÄS MER

  3. 3. Cosmological models, nonideal fluids and viscous forces in general relativity

    Författare :Daniele Gregoris; Kjell Rosquist; Alan Coley; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; gravity; exact model; black hole; friction; Theoretical Physics; teoretisk fysik;

    Sammanfattning : This thesis addresses the open questions of providing a cosmological model describing an accelerated expanding Universe without violating the energy conditions or a model that contributes to the physical interpretation of the dark energy. The former case is analyzed considering a closed model based on a regular lattice of black holes using the Einstein equation in vacuum. LÄS MER

  4. 4. Empirical Sudies in Trade, Growth and Integration

    Författare :Rasha M Tostensson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agglomeration; Urban Giants; Sensitivity Analysis; Income Distribution; Comparative Costs; Gravity Equation; Trade Volume; trade in the Middle East and North Africa; Total factor Productivity; Knowledge Transfer; Long-Run Growth; European Integration; Trade barriers.; International commerce; Internationell ekonomi;

    Sammanfattning : The present study is composed of a series of six independent yet related articles treating various aspects of international trade and economic growth. In Chapter two the effects of European Integration (EI) on long-run economic growth is studied. Contrary to earlier empirical results long-run effects of EI are identified. LÄS MER

  5. 5. Bilateral shipping and trade : Swedish-Finnish experiences in the post-war period

    Författare :Lars Fredrik Andersson; Olle Krantz; Jari Ojala; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic history; Economic history; convergence; economic integration; trade; bilateral; intra-industrial trade; inter-industrial trade; shipping; ferry services; gravity equation; economies of scope; economies of scale; economies of density; post-war period; Ekonomisk historia; Economic history; Ekonomisk historia;

    Sammanfattning : This thesis explores the bilateral shipping and trade between Finland and Sweden during the post-war period. It comprises five articles and one introductory chapter for which the common point of departure is the growth and transformation of bilateral trade and shipping. LÄS MER
