She plans to use the grant to investigate various effective and efficient strategies for caching information, including audio and video files, on such distributed systems as the World Wide Web. Tavanapong says her research should have a significant impact on the evolution of the World Wide Web and could lead to a development of a better distributed information-sharing paradigm other than the Web. Yang says that random errors occur in statistical data in various academic disciplines. He will research generally dependent random errors instead of independent or short-range dependent errors as is usually assumed. Long-range dependence refers to the case when the correlation between two errors remains strong even when two observations are far apart either in space or in time.
Statistical issues become much more complicated when long-range dependence happens.
