This monograph presents the Timed Input/Output Automaton (TIOA) modeling framework, a basic mathematical framework to support description and analysis of timed (computing) systems. Timed systems are systems in which desirable correctness or performance properties of the system depend on the timing of events, not just on the order of their occurrence. Timed systems are employed in a wide range of domains including communications, embedded systems, real-time operating systems, and automated control. Many applications involving timed systems have strong safety, reliability, and predictability requirements, which make it important to have methods for systematic design of systems and rigorous analysis of timing-dependent behavior. The TIOA framework also supports description and analysis of timed distributed algorithms -- distributed algorithms whose correctness and performance depend on the relative speeds of processors, accuracy of local clocks, or communication delay bounds. Such algorithms arise, for example, in traditional and wireless communications, networks of mobile devices, and shared-memory multiprocessors. The need to prove rigorous theoretical results about timed distributed algorithms makes it important to have a suitable mathematical foundation. An important feature of the TIOA framework is its support for decomposing timed system descriptions. In particular, the framework includes a notion of external behavior for a timed I/O automaton, which captures its discrete interactions with its environment. The framework also defines what it means for one TIOA to implement another, based on an inclusion relationship between their external behavior sets, and defines notions of simulations, which provide sufficient conditions for demonstrating implementation relationships. The framework includes a composition operation for TIOAs, which respects external behavior, and a notion of receptiveness, which implies that a TIOA does not block the passage of time. The TIOA framework also defines the notion of a property and what it means for a property to be a safety or a liveness property. It includes results that capture common proof methods for showing that automata satisfy properties.

Since the publication of earlier editions of this book, China's political and economic landscapes have changed dramatically, with the rise of new leadership, evolving alliances, tariff wars, educational policies and technological advancements. Focusing on Chinese-American ventures, this expanded and revised edition chronicles the investments that have marked China's astonishing growth in the 21st century. Adding another dimension to the exploration of Chinese-American commerce, this edition discusses China's roots in Confucian identity and its effect on modern business culture. Case studies of American businesses that have been successful in China are included. Reflecting upon the changing nature of Chinese consumerism and international corporate behavior, the authors close with specific suggestions for those interested in doing business in China.

This volume contains the proceedings of the Third International Workshop on Hybrid Systems: Computation and Control (HSCC 2000), which was held on March 23-25, 2000, in Pittsburgh, Pennsylvania. The proceedings of the rst two workshops in this series were published by Springer-Verlag, in the Lecture Notes in Computer Science series, as volumes 1386 and 1569. The focus of the Hybrid Systems workshop series is on modeling, control, synthesis, design, and veri cation of hybrid systems. A hybrid system is a th- reticalmodelforacomputercontrolledengineeringsystem, withadynamicsthat evolvesbothinadiscretestatesetandinafamilyofcontinuousstatespaces.- brid systems researchis motivated by, for example, controlof electro-mechanical systems(robots), air tra ccontrol, controlofautomatedfreeways, andchemical process control. The research area of hybrid systems overlaps both with c- puter science and with control theory. The workshop series is intended to foster the interaction between researchers from these elds in addressing problems in this new domain. The scientic program of the workshop consisted of four invited talks and 32 contributed talks. The following researcherspresented invited talks: K. Butts (Ford Research, USA), N. Leveson (MIT, USA), A. Sangiovanni-Vincentelli (U. California, Berkeley, USA), and B. Williams (MIT, USA). The contributed talks were based on the papers in these proceedings. The program committee, chaired by the editors, selected the 32 contributed papers out of 71 submitted papers.

Chinese schools are thought to have begun in the Western Zhou (11th century to 770 B.C.), and continued through Confucius' time (551-479 B.C., and far beyond), emphasizing the "six arts"-ritual, music, archery, charioteering, history (including calligraphy), and mathematics. Extrapolating, adapting, and charting these Confucian ideals through several historic eras, the authors use a systems theory-based web model to demonstrate these cultural in uences on Chinese higher education. The authors also argue that this "Confucian" web deeply in uenced Deng Xiaoping's "long march" towards China's global development. Political, financial, technological, social and cultural imperatives of China's entrance into the global mainstream have, in turn, further affected the escalating evolution of education in China's universities. The authors-professors in both the American and the Chinese higher education systems-also develop an argument for delving deeply into culture, utilizing historical-critical methodology, buttressed by a conceptual understanding useful in analyzing the development of similar systems throughout the world. In addition, they present an historic, multi-faceted view of China's many incursions into the global world system, to build a truly astonishing higher education system in 2009. This rapid response further illustrates the strong foundation and societal and governmental support-upon which the current Chinese educational system continues to build.
