21. Metal-assisted chemical etching for nanofabrication of hard X-ray zone plates
Abstract : Hard X-ray scanning microscopes, or nanoprobes, make it possible to image samples and probe their chemical, elemental and structural properties at nanoscale resolution. This is enabled by the use of nanofocusing optics. Commonly used optics in nanoprobes for high resolution X-ray experiments are zone plates. READ MORE

22. Differential railway track settlement in a transition zone – Field measurements and numerical simulations
Abstract : In a transition zone between two different railway track forms, there is a discontinuity in track structure leading to a gradient in track stiffness. Examples include transitions between different superstructures, e.g., slab track to ballasted track, and/or between different substructures, e. READ MORE

23. Implementation and Experimental Evaluation of Wireless Ad hoc Routing Protocols
Abstract : A wireless ad hoc network consists of a number of mobile nodes that temporarily form a dynamic infrastructure-less network. New routing protocols that can adapt to the frequent topology changes induced by node mobility and varying link qualities are needed. READ MORE

24. Speciation and Metabolic rate : Insights from an avian hybrid zone
Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE
