Currently, privatization and regulatory reform are often viewed as the solution to the problem of poor performance by telecommunications and other public utilities. This volume argues that these high expectations may not always be met because of the way a country's institutions and systems interact.

This glossary contains more than 5,000 technical terms and definitions that were standardized by the federal government for use by international and U.S. government telecommunications specialists. It includes international and national terms drawn from the International Telecommunication Union, the International Organization for Standardization, the TIA, ANSI, and others.

Neurofuzzy and fuzzyneural techniques as tools of studying and analyzing complex problems are relatively new even though neural networks and fuzzy logic systems have been applied as computational intelligence structural e- ments for the last 40 years. Computational intelligence as an independent sci- tific field has grown over the years because of the development of these str- tural elements. Neural networks have been revived since 1982 after the seminal work of J. J. Hopfield and fuzzy sets have found a variety of applications since the pub- cation of the work of Lotfi Zadeh back in 1965....
