Many of the everyday activities and information needs of mobile users are related to context. Recent studies, however, reveal that mobile users find their information needs inadequately addressed by current mobile ICT. This book describes an infrastructure for the selective replication of RDF data to mobile devices while considering current and future information needs of mobile users and the different contexts they are operating in. It discusses areas where context-aware computing is enhanced with technologies, languages, and concepts from the Semantic Web and contains a comparative study...

Methanol is one of the most important industrial base chemicals and also a starting material for many organic syntheses. A steadily rising amount is used as fuel or fuel additive because methanol can serve as liquid hydrogen carrier. In the chemical industry, methanol is produced from synthesis gas over Cu/ZnO based catalysts. The catalyst is prepared by a multi-step synthesis (co-precipitation, calcination, reduction). Already in early stages of the preparation structural characteristics can provide indications for the resulting activity of the final catalyst. In order to investigate...
