1. On the Use of LaserInduced Incandescence for Soot Diagnostics: From Theoretical Aspects to Applications in Engines
Abstract : The laserinduced incandescence technique (LII) is a laserbased diagnostic technique for measurements of soot volume fraction and particle size. The technique relies on detection of incandescent light from soot particles heated to around 4000 K using nanosecond laser pulses. READ MORE

2. Pierced, Wrapped and Torn : Aspects of String Theory Compactifications
Abstract : An outstanding problem in physics is to find a unified framework for quantum mechanics and general relativity. This is required for a better understanding of black holes and the early cosmology of the universe. String theory provides such a unification. In this thesis, we study aspects of compactifications of type IIB string theory. READ MORE

3. Aspects of the Duality between Supersymmetric YangMills Theory and String Theory
Abstract : This thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. READ MORE

4. Making Maps and Keeping Logs : Quantum Gravity from Classical Viewpoints
Abstract : This thesis explores three different aspects of quantum gravity. First we study D3brane black holes in CalabiYau 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

5. Development and application of MuffinTin Orbital based Green’s function techniques to systems with magnetic and chemical disorder
Abstract : Accurate electronic structure calculations are becoming more and more important because of the increasing need for information about systems which are hard to perform experiments on. Databases compiled from theoretical results are also being used more than ever for applications, and the reliability of the theoretical methods are of utmost importance. READ MORE
