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

2. Three-dimensional analysis of aeromagnetic and gravimetric data of sedimentary basins from Panama, Central America
Abstract : The knowledge of the geology of the sedimentary basins from the Gulf of Panama is still quite limited. There is a lack of data from the basin geometry, the thickness, the continuity and connection between the basins, and from the characteristics of the crystalline basement rocks beneath the sedimentary basins.

3. Conformal Field Theory and the Holgoraphic Principle
Abstract : This thesis is based on five research papers with string theory as the least common denominator. The text is divided in two parts. The first part is an introduction to the constructions used in the papers; string theory, conformal field theory, topological field theory and three-dimensional gravity. READ MORE

4. 3D Geophysical and Geological Modeling in the Skellefte District: Implications for Targeting Ore Deposits
Abstract : With the advancements in acquisition and processing of seismic reflection data recorded over crystalline rocks, building three-dimensional geologic models becomes increasingly favorable. Because of little available petrophysical data, interpretations of seismic reflection data in hardrock terrains are often speculative. READ MORE

5. Inversion and Joint Inversion of Electromagnetic and Potential Field Data
Abstract : In this thesis, four inversion problems of different scale and difficulty are solved. Two of them are electromagnetic inverse problems. Two more are joint inversion problems of potential field data and other types of data. READ MORE
