Taking a conceptual approach, this book studies the economic development of the four East Asian economies since 1950. The author summarizes and reconsiders many of the arguments and findings that supported and explained the economic 'miracles' of Hong Kong, Singapore, Taiwan and South Korea, analysing the relationship between economic development, growth and political economy. This pioneering book will stimulate further analysis of East Asian development. It will be of essential interest to scholars in East Asian economics, and all those interested in modern economic development.
Hong Kong has been one of the fastest growing East Asian economies since the end of the Second World War. The adoption and practice of economic freedom have been major pillars in its economic success. Indeed, the experience of Hong Kong has served as a reference for other emerging economies in the region. The scope of the book elaborates the context and ingredients of economic freedom that have brought success and prosperity to Hong Kong. With sovereignty reversion to China in 1997, it is even more relevant to see how economic freedom is shaping and adapting to the new environment.There exist a number of economic indices based on economic freedom. Hong Kong has been ranked as the freest economy in the world for a number of consecutive years. While the economic freedom indices compare the performance of a large number of word economies, there is a lack of economic literature that studies the absolute level of economic freedom of a single economy. This book boldly serves the purpose of elaborating on the absolute performance of economic freedom in the world's freest economy. It is, therefore, the first of its kind and unique in its field. Numerous areas of studies related to economic freedom are examined, studied and elaborated so that readers can have a full and comprehensive understanding of the content of economic freedom in Hong Kong.

This book comprehensively reviews searchable encryption, which represents a series of research developments that directly enable search functionality over encrypted data. The book majorly covers: 1) the design and implementation of encrypted search algorithms, data structures, and systems that facilitate various forms of search over always-encrypted databases; 2) different threat models, assumptions, and the related security guarantees, when using searchable encryption in the real-world settings; and 3) latest efforts in building full-fledged encrypted database systems that draw insights from searchable encryption constructions. The book fits in the timely context, where the necessity of safeguarding important and sensitive data has been globally recognized. Traditional security measures, such as storing data behind network firewalls and layers of access control mechanisms to keep attackers out, are no longer sufficient to cope with the expanding landscape of surging cyber threats. There is an urgent call to keep sensitive data always encrypted to protect the data at rest, in transit, and in use. Doing so guarantees data confidentiality for owners, even if the data is out of their hands, e.g., hosted at in-the-cloud databases. The daunting challenge is how to perform computation over encrypted data. As we unfold in this book, searchable encryption, as a specific line of research in this broadly defined area, has received tremendous advancements over the past decades. This book is majorly oriented toward senior undergraduates, graduate students, and researchers, who want to work in the field and need extensive coverage of encrypted database research. It also targets security practitioners who want to make well-informed deployment choices of the latest advancements in searchable encryption for their targeted applications. Hopefully, this book will be beneficial in both regards.
The 5G technology has been commercialized worldwide and is expected to provide superior performance with enhanced mobile broadband, ultra-low latency transmission, and massive IoT connections. Meanwhile, the edge computing paradigm gets popular to provide distributed computing and storage resources in proximity to the users. As edge services and applications prosper, 5G and edge computing will be tightly coupled and continuously promote each other forward. Embracing this trend, however, mobile users, infrastructure providers, and service providers are all faced with the energy dilemma. On the user side, battery-powered mobile devices are much constrained by battery life, whereas mobile platforms and apps nowadays are usually power-hungry. At the infrastructure and service provider side, the energy cost of edge facilities accounts for a large proportion of operating expenses and has become a huge burden. This book provides a collection of most recent attempts to tackle the energy issues in mobile edge computing from new and promising perspectives. For example, the book investigates the pervasive low-battery anxiety among modern mobile users and quantifies the anxiety degree and likely behavior concerning the battery status. Based on the quantified model, a low-power video streaming solution is developed accordingly to save mobile devices' energy and alleviate users' low-battery anxiety. In addition to energy management for mobile users, the book also looks into potential opportunities to energy cost saving and carbon emission reduction at edge facilities, particularly the 5G base stations and geo-distributed edge datacenters.

This book analyzes the relation between the flow time and poetic speech in drama and rhetoric. It begins with the classical understanding of time as flux, and its problems and paradoxes entailing from Aristotle, Augustine, Kant and Husserl. The reader will see how these problems unfold and find resolutions through dramatic speech and rhetoric which has an essential relation to the flow of time. It covers elements in poetic speech such as affect, rhythm, metaphor, and syntax. It uses examples from classical rhetorical theories by Aristotle, Cicero, Quintilian, dramatic speeches from Shakespeare, as well as other modern dramatic texts by Chekhov, Beckett, Jelinek and Sarah Kane. This book appeals to students and academic researchers working in the philosophical fields of aesthetics and phenomenology as well those working in theater and the performing arts.
This book presents operational modal analysis (OMA), employing a coherent and comprehensive Bayesian framework for modal identification and covering stochastic modeling, theoretical formulations, computational algorithms, and practical applications. Mathematical similarities and philosophical differences between Bayesian and classical statistical approaches to system identification are discussed, allowing their mathematical tools to be shared and their results correctly interpreted. The authors provide their data freely in the web at https://doi.org/10.7910/DVN/7EVTXG Many chapters can be used as lecture notes for the general topic they cover beyond the OMA context. After an introductory chapter (1), Chapters 2–7 present the general theory of stochastic modeling and analysis of ambient vibrations. Readers are first introduced to the spectral analysis of deterministic time series (2) and structural dynamics (3), which do not require the use of probability concepts. The concepts and techniques in these chapters are subsequently extended to a probabilistic context in Chapter 4 (on stochastic processes) and in Chapter 5 (on stochastic structural dynamics). In turn, Chapter 6 introduces the basics of ambient vibration instrumentation and data characteristics, while Chapter 7 discusses the analysis and simulation of OMA data, covering different types of data encountered in practice. Bayesian and classical statistical approaches to system identification are introduced in a general context in Chapters 8 and 9, respectively. Chapter 10 provides an overview of different Bayesian OMA formulations, followed by a general discussion of computational issues in Chapter 11. Efficient algorithms for different contexts are discussed in Chapters 12–14 (single mode, multi-mode, and multi-setup). Intended for readers with a minimal background in mathematics, Chapter 15 presents the ‘uncertainty laws’ in OMA, one of the latest advances that establish the achievable precision limit of OMA and provide a scientific basis for planning ambient vibration tests. Lastly Chapter 16 discusses the mathematical theory behind the results in Chapter 15, addressing the needs of researchers interested in learning the techniques for further development. Three appendix chapters round out the coverage. This book is primarily intended for graduate/senior undergraduate students and researchers, although practitioners will also find the book a useful reference guide. It covers materials from introductory to advanced level, which are classified accordingly to ensure easy access. Readers with an undergraduate-level background in probability and statistics will find the book an invaluable resource, regardless of whether they are Bayesian or non-Bayesian.
This book starts with the basic ideas in uncertainty propagation using Monte Carlo methods and the generation of random variables and stochastic processes for some common distributions encountered in engineering applications.
