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

   Author : Majid Beiki; Laust Pedersen; Mehrdad Bastani; Mark Pilkington; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. The prospects for the East African Monetary Union : An empirical analysis

   Author : Yvonne Umulisa; R. Scott Hacker; Almas Heshmati; Guglielmo Maria Caporale; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : This thesis operationalizes the theory of optimum currency areas, which describes the preconditions (criteria) that countries must fulfill prior to forming a monetary union. In light of the different dimensions of the theory that are examined, the empirical findings from the four papers in this thesis seem to favor forming a monetary union among East African Community (EAC) partner states.

5. 3. Geophysical studies in the western part of the Siljan Ring Impact Crater

   Author : Harbe Muhamad; Christopher Juhlin; Alireza Malehmir; Daniel Sopher; Lars Nilsen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Siljan ring impact structure; Seismic reflection; Down-hole logging; Gravity; Magnetic; Tomography; Paleozoic rocks;

   Abstract : This thesis utilizes several geophysical methods to study the Siljan Ring impact structure, focusing on the western part of the structure. This thesis, and the three papers upon which it is based, reports on attempts to delineate the Paleozoic rocks at depth within the annular ring graben and characterize their structure. READ MORE

6. 4. Making Maps and Keeping Logs : Quantum Gravity from Classical Viewpoints

   Author : Niklas Johansson; Ulf Danielsson; Jan de Boer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; black holes in string theory; Calabi-Yau geometry; flux compactifications; three-dimensional gravity; Mathematical physics; Matematisk fysik; Theoretical Physics; teoretisk fysik;

   Abstract : This thesis explores three different aspects of quantum gravity. First we study D3-brane black holes in Calabi-Yau compactifications of type IIB string theory. Using the OSV conjecture and a relation between topological strings and matrix models we show that some black holes have a matrix model description. READ MORE

7. 5. Compact Relativistic Matter Shells with Massless and Charged Particles

   Author : Maximilian Thaller; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spherical Symmetry; massless Einstein-Vlasov system; Einstein-Vlasov-Maxwell system; Static Solutions; Vlasov matter; General Relativity; Einstein-Vlasov-Maxwell system;

   Abstract : The Vlasov model is a matter model that is widely used in physics. In the context of astrophysics and cosmology it describes an ensemble of self gravitating, collisionless particles. These particles can be interpreted as for example ions, stars, or galaxies. READ MORE
