This thesis uses the link structure of the World Wide Web as a basis to create better search engines. It focuses on the HITS algorithm, which was the first algorithm to up the link topology. HITS is implemented with slight modifications and tested with variations of its input parameters. It is also used in order to discover emerging communities in cyberspace. Other related algorithms, which use the link structure of the web as an undirected graph are described and compared with HITS. Finally, an attempt to combine link-based with text-based analysis in order to create more accurate search methods ...

The Grid initiative provides an infrastructure for distributed computation among widely distributed high-performance computers. This will allow for exchanging and processing very large amounts of data. There are a huge number of applications that are geographically distributed such as multi-point radio facility for astrophysics, space physics, atmospheric physics, and radio research, utilizing very high performance Grid Computing. It is expected that similar applications to become important in commercial settings, initially for scientific and technical computing applications and then for commercial ...
