Taiwan, once one of the world's leading manufacturing economies, is now transforming into a service economy, with an emphasis on knowledge-based services. This metamorphosis has not been easy. As well as major changes in the industrial sector, human resource and policy development have been required, the experiences and implications of which are addressed in this book. Although Taiwan is only in the initial stage of transition from a material- or capital-based economy to a knowledge-based economy, the process has already provided valuable lessons to be learnt. The ramification of transformations in manufacturing, agriculture, finance, services, and the information technology industry are examined and discussed. Tain-Jy Chen and Joseph S. Lee go on to reveal the problems and difficulties that Taiwan has encountered in creating itself a new knowledge based economy, including its outmoded service sector, the inability of businesses to pursue global production and services, and the lack of capacity to create knowledge and to innovate. Providing a discernible insight into the transformation of one of the most prominent newly industrialized countries into a knowledge-based economy, this book will greatly appeal to academics, researchers, and those with a specific interest in knowledge management or Asian economies, as well as to economic analysts.
This book investigates the performance limitation issues in networked feedback systems. The fact that networked feedback systems consist of control and communication devices and systems calls for the integration of control theory and information theory. The primary contributions of this book lie in two aspects: the newly-proposed information-theoretic measures and the newly-discovered control performance limitations. We first propose a number of information notions to facilitate the analysis. Using those notions, classes of performance limitations of networked feedback systems, as well as state estimation systems, are then investigated. In general, the book presents a unique, cohesive treatment of performance limitation issues of networked feedback systems via an information-theoretic approach. This book is believed to be the first to treat the aforementioned subjects systematically and in a unified manner, offering a unique perspective differing from existing books.
This authored monograph presents a study on fundamental limits and robustness of stability and stabilization of time-delay systems, with an emphasis on time-varying delay, robust stabilization, and newly emerged areas such as networked control and multi-agent systems. The authors systematically develop an operator-theoretic approach that departs from both the traditional algebraic approach and the currently pervasive LMI solution methods. This approach is built on the classical small-gain theorem, which enables the author to draw upon powerful tools and techniques from robust control theory. The book contains motivating examples and presents mathematical key facts that are required in the subsequent sections. The target audience primarily comprises researchers and professionals in the field of control theory, but the book may also be beneficial for graduate students alike.
At 90 nm, wires account for nearly 75% of the total delay in a circuit. Even more insidious, however, is that among nearly 40% of these nets, more than 50% of their total net capacitance are attributed to the cross-coupling capacitance between neighboring signals. At this point a new design and optimization paradigm based on real wires is required. Nanometer routers must prevent and correct these effects on-the-fly in order to reach timing closure.

Public housing was once an important strand in western housing policies, but is seldom seen as a mainstream policy instrument for the future. In contrast, in many East Asian countries large public housing programs are underway. Behind these generalizations, there are exceptions, too. By including perspectives of scholars from across the world, this book provides new insights into public housing in its various forms. It contains in-depth chapters on public housing in five East Asian countries and six Western countries, together with three comparative overview chapters.

This book is intended for researchers active in the field of (blind) system identification and aims to provide new identification ideas/insights for dealing with challenging system identification problems. It presents a comprehensive overview of the state-of-the-art in the area, which would save a lot of time and avoid collecting the scattered information from research papers, reports and unpublished work. Besides, it is a self-contained book by including essential algebraic, system and optimization theories, which can help graduate students enter the amazing blind system identification world with less effort.
For both their theoretical and practical impact, time-delay systems have been an enduring theme in the study of differential equations, stochastic processes, game theory, and systems theory. The subject has broad applications to a number of areas, including mechanical, electrical and chemical engineering, mathematics, biology, and economics. This book is a self-contained, coherent presentation of the background and progress of the stability of time-delay systems. Focusing on techniques, tools, and advances in numerical methods and optimization algorithms, the authors develop material, which up until now, has been scattered in technical journals and conference proceedings. Special emphasis is placed on systems with uncertainty and stability criteria which can be computationally implemented. Features and Topics: * Systematic and comprehensive coverage of robust stability for time-delay systems, including time-domain and frequency-domain approaches * Stability criteria formulated using linear matrix inequalities (LMI), providing a powerful toolbox for practicing engineers * Strong stability conditions developed to provide a solid basis for design of feedback control and filtering * Balance of intuition and rigor, stressing concepts rather than technical details * Emphasis on comparisons and connections among various approaches * Mathematical prerequisites integrated within each chapter, with more elementary material covered in two appendices Requiring only basic knowledge of linear systems and Lyapunov stability theory, Stability of Time-Delay Systems will be accessible to a broad audience of researchers, professional engineers, and graduate students. It may be used for self-study or as a reference; portions of the text may be used in advanced graduate courses and seminars.
There is an increasing demand for dynamic systems to become more safe and reliable. This requirement extends beyond the normally accepted safety-critical systems of nuclear reactors and aircraft where safety is paramount important, to systems such as autonomous vehicles and fast railways where the system availability is vital. It is clear that fault diagnosis (including fault detection and isolation, FDI) has been becoming an important subject in modern control theory and practice. For example, the number of papers on FDI presented in many control-related conferences has been increasing steadily. The subject of fault detection and isolation continues to mature to an established field of research in control engineering. A large amount of knowledge on model-based fault diagnosis has been ac cumulated through the literature since the beginning of the 1970s. However, publications are scattered over many papers and a few edited books. Up to the end of 1997, there is no any book which presents the subject in an unified framework. The consequence of this is the lack of "common language," dif ferent researchers use different terminology. This problem has obstructed the progress of model-based FDI techniques and has been causing great concern in research community. Many survey papers have been published to tackle this problem. However, a book which presents the materials in a unified format and provides a comprehensive foundation of model-based FDI is urgently needed."
The overseas Chinese democracy movement (OCDM) is one of the world's longest-running and most difficult exile political campaigns. This unique book is a rare and comprehensive account of its trajectory since its beginnings in the early 1980s, examining its shifting operational environment and the diversification of its activities, as well as characterizing its distinctive features in comparison to other exile movements. Chen Jie takes an empirical approach to the history of the OCDM, drawing on extensive primary sources and his own significant field research, including interviews with major dissident figures. He explores the changing roles of activists since the events of Tiananmen Square and the movement's subsequent heyday, highlighting the diverse positions occupied today as a result of internal division and evolving geopolitical circumstances. Using the analytical framework of exile politics, Chen also examines such issues as China's relationship with Taiwan and the implications of the expanding global Chinese diaspora. Academics and postgraduate students studying Chinese politics and international relations, as well as those with an interest in diaspora studies, will find this book invaluable. It will also provide important understanding of Chinese exiles and activists to government officials and those working in international political foundations, funding bodies and human rights organisations.
Multi-objective optimization problems (MOPs) and uncertain optimization problems (UOPs) which widely exist in real life are challengeable problems in the fields of decision making, system designing, and scheduling, amongst others. Decomposition exploits the ideas of aEURO~making things simpleaEURO (TM) and aEURO~divide and conqueraEURO (TM) to transform a complex problem into a series of simple ones with the aim of reducing the computational complexity. In order to tackle the abovementioned two types of complicated optimization problems, this book introduces the decomposition strategy and conducts a systematic study to perfect the usage of decomposition in the field of multi-objective optimization, and extend the usage of decomposition in the field of uncertain optimization.
This revised and expanded second edition is an in-depth study of the change point problem from a general point of view, as well as a further examination of change point analysis of the most commonly used statistical models. Change point problems are encountered in such disciplines as economics, finance, medicine, psychology, signal processing, and geology, to mention only several. More recently, change point analysis has been found in extensive applications related to analyzing biomedical imaging data and gene expression data. Extensive examples throughout the text emphasize key concepts and different methodologies used. New examples of change point analysis in modern molecular biology and other fields such as finance and air traffic control have been added to this second edition.
This book presents a systematic and unified approach for modern nonparametric treatment of missing and modified data via examples of density and hazard rate estimation, nonparametric regression, filtering signals, and time series analysis. All basic types of missing at random and not at random, biasing, truncation, censoring, and measurement errors are discussed, and their treatment is explained. Ten chapters of the book cover basic cases of direct data, biased data, nondestructive and destructive missing, survival data modified by truncation and censoring, missing survival data, stationary and nonstationary time series and processes, and ill-posed modifications. The coverage is suitable for self-study or a one-semester course for graduate students with a prerequisite of a standard course in introductory probability. Exercises of various levels of difficulty will be helpful for the instructor and self-study. The book is primarily about practically important small samples. It explains when consistent estimation is possible, and why in some cases missing data should be ignored and why others must be considered. If missing or data modification makes consistent estimation impossible, then the author explains what type of action is needed to restore the lost information. The book contains more than a hundred figures with simulated data that explain virtually every setting, claim, and development. The companion R software package allows the reader to verify, reproduce and modify every simulation and used estimators. This makes the material fully transparent and allows one to study it interactively. Sam Efromovich is the Endowed Professor of Mathematical Sciences and the Head of the Actuarial Program at the University of Texas at Dallas. He is well known for his work on the theory and application of nonparametric curve estimation and is the author of Nonparametric Curve Estimation: Methods, Theory, and Applications. Professor Sam Efromovich is a Fellow of the Institute of Mathematical Statistics and the American Statistical Association.
What kind of role can the middle class play in potential democratization in such an undemocratic, late developing country as China? To answer this profound political as well as theoretical question, Jie Chen explores attitudinal and behavioral orientation of China's new middle class to democracy and democratization. Chen's work is based on a unique set of data collected from a probability-sample survey and in-depth interviews of residents in three major Chinese cities, Beijing, Chengdu and Xi'an-each of which represents a distinct level of economic development in urban China-in 2007 and 2008. The empirical findings derived from this data set confirm that (1) compared to other social classes, particularly lower classes, the new Chinese middle class-especially those employed in the state apparatus-tends to be more supportive of the current Party-state but less supportive of democratic values and institutions; (2) the new middle class's attitudes toward democracy may be accounted for by this class's close ideational and institutional ties with the state, and its perceived socioeconomic wellbeing, among other factors; (3) the lack of support for democracy among the middle class tends to cause this social class to act in favor of the current state but in opposition to democratic changes. The most important political implication is that while China's middle class is not likely to serve as the harbinger of democracy now, its current attitudes toward democracy may change in the future. Such a crucial shift in the middle class's orientation toward democracy can take place, especially when its dependence on the Party-state decreases and perception of its own social and economic statuses turns pessimistic. The key theoretical implication from the findings suggests that the attitudinal and behavioral orientations of the middle class-as a whole and as a part-toward democratic change in late developing countries are contingent upon its relationship with the incumbent state and its perceived social/economic wellbeing, and the middle class's support for democracy in these countries is far from inevitable.

Toward Better Governance in China takes a fresh look at the latest efforts made by Chinese leaders to promote governance-based reform. It asserts that the improvement of governance has now become one of the breakthrough points of the much anticipated political reform. Although the Chinese government continues to play down expectations about political reform, many small-scale reform experiments have been quietly undertaken by Chinese leaders at various levels in recent years, including the new round of administrative reform centered on the creation of "super ministries," the enlargement of inner-party democracy within the Chinese Communist Party (CCP), the strengthening of local legislative bodies, and judicial reform designed to promote judicial independence and rule of law. This strategy calls for strengthening governing capacity and changing government functions. One of the advantages in placing the improvement of governance first is that it is less risky than embarking upon a full-scaled electoral reform. Electoral democracy is undoubtedly an important element in a functional democracy. But equally important is the effectiveness, transparency, accountability, and openness of the governing process. Better governance implies greater transparency, open deliberation and participation, and less adversarial political confrontation and conflict. If constructed properly, China may become the sort of democratic administration or administrative democracy that Robert Dahl discussed in 1947. Clearly, political reform of this kind does not follow the conventional wisdom of a democratic transition which places heavy emphasis on electoral reform or the precedence of the electoral reform to the government reform. This book is intended to shed some new light on the ongoing debate about the direction of China's political development.
Taiwanese foreign direct investment rapidly expanded in the mid-1980s when the domestic wage rate and the value of the Taiwanese currency skyrocketed simultaneously. Losing their competitive edge at home, many Taiwanese firms relocated to lower wage countries; mainly Southeast Asia and China. Taiwanese Firms in Southeast Asia provides a comprehensive review of Taiwan's direct investment in Southeast Asia, including Indonesia, Malaysia, Thailand, the Philippines and Vietnam. It also explores the motivation behind investment in Asia, Europe and the US. In most countries, incidence of foreign direct investment is positively correlated with firm size. However, in Taiwanese firms, the opposite is true. The book examines the reasons for this and assesses the difference in practice between small and large firms conducting foreign direct investment, focusing on the manufacturing sector. The book also includes an original, comprehensive survey and a series of interviews with Taiwanese parent firms and their subsidiaries in Southeast Asia. The authors conclude that networking underscores the core competitiveness of Taiwanese firms and when these firms invest abroad, they attempt to maintain a close connection with domestic networks to retain competitiveness and flexibility. However, they will have difficulty in sustaining this in the long-term because co-ordination of production across national borders requires intensive input of managerial resources which are scarce among Taiwanese firms. In the long-term, they have to localize and integrate themselves into the local networks. The book is a result of joint research efforts by Taiwanese, American and Southeast Asian scholars and will be required reading for students and scholars of economies in Southeast Asia, international business, Asian studies and multinational enterprise.
This book provides an alternative theoretical approach to the study of ideology in U.S. foreign policy, emphasizing the importance of ideology in foreign relations. Unlike traditional approaches, which tend to neglect the variability of ideological influence, Chen's approach postulates a two-step causal relationship that explains changes in the strength of ideology and their influence on U.S. foreign policy. Changes in objective conditions cause changes in the strength of ideology, and these changes, in turn, create fluctuations in U.S. foreign policy. Chen explores that causal relationship empirically through detailed case studies of U.S. China policy and also, in his concluding analysis, looks at ideology and recent U.S. policies toward Eastern Europe and the Middle East. This book will be of interest to teachers and students of international relations.
