Since the publication of the first edition, the CTI world has changed significantly. Where it was once focused on the integration of voice systems with computers, the focus is now on IP-based voice, or converged networks and services. Today, the telcos are upgrading their systems from circuit-switched to IP-based packet-switched networks. Companies like Cisco Systems and Dow Chemical have installed IP-based phones in their offices worldwide, saving millions of dollars in service fees.
Performance and Reliability Analysis of Computer Systems: An Example-Based Approach Using the SHARPE Software Package provides a variety of probabilistic, discrete-state models used to assess the reliability and performance of computer and communication systems. The models included are combinatorial reliability models (reliability block diagrams, fault trees and reliability graphs), directed, acyclic task precedence graphs, Markov and semi-Markov models (including Markov reward models), product-form queueing networks and generalized stochastic Petri nets. A practical approach to system modeling is followed; all of the examples described are solved and analyzed using the SHARPE tool.
This Millennium Boxed Set -- five elegantly printed books that describe their own method of creation -- celebrates Donald E. Knuth's monumental coupling of programming and typography in the TeX and METAFONT systems that are used worldwide by scientists, mathematicians, and others to produce high-quality, aesthetically pleasing text. Originally published in 1986, each volume has changed so much in subsequent printings that nearly every page has been touched. The improvements reflect new developments in digital printing technology; as well as corrections submitted by thousands of volunteers -- making these volumes the most accurate versions yet published. For readers who own earlier printings of Knuth's books, or have holes in their collections, the Millennium Boxed Set makes updating easy. For those who own none of the books, the boxed set is a convenient way to get them all at once.
