Naren Ramakrishnan and Anath Grama discuss another aspect of finding relevant information in large databases in their contribution. They discuss the algorithms, techniques, and methodologies for effective application of scientific data mining.
Returning to the Web theme, Ross Anderson, Frank Stajano, and Jong-Hyeon Lee address the issue of security policies. Their survey of the most significant security policy models in the literature shows how security may mean different things in different contexts.
John Savage, Alan Selman, and Carl Smith take a step back from the applications and address how theoretical computer science has had an impact on practical computing concepts. Finally, Yuan Taur takes a step even further back and discusses the development of the computer chip.
Thus, Volume 55 takes us from the very fundamentals of computer science-the chip-right to the applications and user interface with the Web.
