16. From Art Galleries to Terrain Modelling --- A Meandering Path through Computational Geometry
Abstract : We give approximation and online algorithms as well as data structures for some well studied problems in computational geometry. The thesis is divided into three parts. In part one, we study problems related to guarding, exploring and searching geometric environments. READ MORE

17. Recognition and signaling of DNA double-strand breaks in human cells
Abstract : DNA double-strand breaks (DSBs) are the most toxic type of DNA damage. Fortunately, our cells have highly conserved pathways that detect and repair DSBs. Defects in DSB signaling and DSB repair pathways result in genomic instability that predisposes for cancer development. READ MORE

18. Micro-grinding of titanium
Abstract : Titanium and its alloys are difficult-to-cut materials, commonly used in several application fields, such as: medicine, aerospace, automotive and turbine manufacturing due to their biocompatibility, corrosion resistance, excellent mechanical and thermal properties, and light weight. However, its machining is associated with several difficulties, such as high tool wear, low surface quality, high cutting forces and high costs. READ MORE

19. Structured zeolite adsorbents
Abstract : Zeolites are microporous crystalline aluminosilicates with unique properties, and therefore used in adsorption processes, for membrane separation, in catalysis, and in sensor technologies. Pressure swing adsorption (PSA) is a commonly used technology for purifying gases and is based on the ability of materials like zeolites, to selectively adsorb and desorb particular gas molecules as the gas pressure is increased and reduced, respectively.

20. Process Industry Energy Projects in a Climate Change Conscious Economy
Abstract : Most industrial process plants consume large amounts of energy (usually in the form of steam and electricity) to produce demanded goods, such as beer or paper. However, combustion of fossil fuels has negative external effects on the Earths climate. READ MORE
