1. Multilevel Inverter for Wave Power Conversion
Abstract : This thesis deals with the electrical system analysis of a Wave Energy Converter (WEC) for the objective of grid connection. The Linear Permanent Magnet Generator (LPMG) is modeled and validated with experimental results. The comparison studies establish that this model is useful for the subsequent system modeling and performance analysis. READ MORE

2. Grid Connected Three-Level Converters : Studies for Wave Energy Conversion
Abstract : This thesis presents an electrical system analysis of a wave energy converter (WEC) for the objective of grid connection. To transfer the enormous amount of power from waves to the load centers, efficient power electronic systems are essential. READ MORE

3. Long freight trains and long-term rail surface damage
Abstract : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. READ MORE

4. Cuts and Continuities: Caste-subaltern imaginations of the Bengal famine of 1943
Abstract : The Bengal famine of 1943, in which nearly three million people died, was man-made. A multitude of factors led to the famine, including British colonial policies, war, hoarding and profiteering by local elites and businesses, and existing faultlines of caste, class and gender. READ MORE

5. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides
Abstract : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. READ MORE
