Hydrologic data collection over scales from centimemrs to continents, from minutes to years is difficult and expensive, so hydrologic models usually conceptualize processes based on simple, often homogeneous, views of nature. This forced oversimplification impedes cientific understanding and management of water resources. As the focus of hydrologic research shifts to larger regional and global ...

Today, with the great development of science and technology, it seems to be more and more important to develop renewable energy sources. In this thesis, I would like to introduce something about Chinese water resources. The renewable energy sources can generate electricity. Furthermore, hydropower is the most often used energy in the world. Hydropower develops quickly in recent years in China a...

Techniques such as mobility and distribution are often used to overcome limitations of resources such as the amount of memory or the necessity for specialised devices. Indeed, questions related to such limitations are crucial in matters of security, compilation and quality of service. However, few attempts have been made at formalising this notion of resource limitation in presence of mobility,...
