1. Multipole moments of axisymmetric spacetimes
Abstract : In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion. READ MORE

2. Multipole Moments of Stationary Spacetimes
Abstract : In this thesis we study the relativistic multipole moments for stationary asymptotically flat spacetimes as introduced by Geroch and Hansen. These multipole moments give an asymptotic description of the gravitational field in a coordinate independent way. READ MORE

3. Analysis of Industrial Microwave Ovens
Abstract : This thesis deals with the analysis and design of microwave ovens used in the food industry. Such analysis is desirable in order to optimize the performance of the ovens and to reduce the time and expenses of developing new or improved ovens. READ MORE

4. Fast Numerical Techniques for Electromagnetic Problems in Frequency Domain
Abstract : The Method of Moments is a numerical technique for solving electromagnetic problems with integral equations. The method discretizes a surface in three dimensions, which reduces the dimension of the problem with one. A drawback of the method is that it yields a dense system of linear equations. READ MORE

5. A flexible and polarizable water model built on interpolated multipoles
Abstract : Water has a rich phase diagram with regions of meta-stability, the prime examples being super-cooled and super-heated liquid water.Below ca 50 °C, water exhibits unusual and not yet fully explained anomalous thermodynamic properties upon cooling, for example a minimum in compressibility at 46 °C, a minimum in heat capacity at 35 °C, a density maximum at 4 °C, and a compressibility maximum at -44 °C in the supercooled liquid, at ambient pressure.
