This book presents in detail the theory, processes and equipment involved in cold rolling precision forming technologies, focusing on spline and thread shaft parts. The main topics discussed include the status quo of research on these technologies; the design and calculation of process parameters; the numerical simulation of cold rolling forming processes; and the equipment used. The mechanism of cold rolling forming is extremely complex, and research on the processes, theory and mechanical analysis of spline cold rolling forming has remained very limited to date. In practice, the forming processes and production methods used are mainly chosen on the basis of individual experience. As such, there is a marked lack of both systematic, theory-based guidelines, and of specialized books covering theoretical analysis, numerical simulation, experiments and equipment used in spline cold rolling forming processes. Illustrated using tables, 3D photographs and formula derivations, this book fills that gap in the literature.
Wang Gungwu is one of the most influential historians of his generation. Initially renowned for his pioneering work on the structure of power in early imperial China, he is more widely known for expanding the horizons of Chinese history to include the histories of the Chinese and their descendents outside China. It is probably no coincidence, Philip Kuhn observes, that the most comprehensive historian of the Overseas Chinese is the historian most firmly grounded in the history of China itself. This book is a celebration of the life, work, and impact of Professor Wang Gungwu over the past four decades. It commemorates his contribution to the study of Chinese history and the abiding influence he has exercised over later generations of historians, particularly in the Asia-Pacific region. The book begins with an historiographical survey by Philip Kuhn (Francis Lee Higginson Professor of History at Harvard University) of Wang Gungwu's enduring contribution to scholarship. It concludes with an engaging oral history of Professor Wang's life, career, and research trajectory. The intervening chapters explore many of the fields in which Wang Gungwu's influence has been felt over the years, including questions of political authority, national identity, commercial life, and the history of the diaspora from imperial times to the present day. Each of these chapters is authored by a former student of Professor Wang, now working and teaching in Hong Kong, Southeast Asia, Australasia, Taiwan and Canada.
Rather than presenting another narrative of Singapore history, The Scripting of a National History: Singapore and Its Pasts studies the constructed nature of the history endorsed by the state, which blurs the distinction between what happened in the past, and how the state intends that past to be understood. The People's Action Party (PAP) government's unbroken mandate to rule has come in no small part from the way it explains its lineage and record to Singaporeans. The power vested in various aspects of Singapore's history is thus examined through a consideration of past and present politics. The authors trace state discourses on Singapore history from the decision immediately after independence to recognize the nineteenth-century British acquisition of the island as its founding moment, to the 1980s and 1990s when an essentially Confucian heritage was recognized under the rubric of "Asian values", and finally to an emphasis on the history of racial fragility and harmony in response to the threat of terrorism in the twenty-first century. Embedded within these discourses is the story of the PAP as the heir of the economic dynamics of the pax Britannica, as an exponent of the morality and righteousness of the Chinese scholar-gentleman, and as the firm hand that balances the interests of the majority Chinese against those of the minority populations, particularly the Malays. The authors examine the underlying template of Singapore history, the negotiation with its immigrant past, and the popularization of history through conscription of national heroes. The chapters range from considering how political leaders claim to be historians by virtue of being the makers of history, to the vicissitudes undergone by two originally private homes turned into symbols of Singapore's Chinese modernity. The Scripting of a National History: Singapore and Its Pasts is highly relevant not only to academics but also for the Singapore general reader interested to see what are meant to be received wisdoms for the citizenry interrogated in a well-reasoned and engaging exercise, as well as for an international readership to whom Singapore has become a fascinating enigma. They may well be intrigued by the anxieties of being Singaporean.
Heritage Sites in Contemporary China: Cultural Policies and Management Practices focuses on cultural heritage policies in China emerging in the period of the 11th and 12th Five Year Plans. Various important Chinese sites across China are investigated, including Luoyang Sui, Daming Gong, Niuheliang, Xinjiang, and Nanyuewang through the dual perspective of archaeological debate and as a case study of policy making. It explores the relationship between policy and the institutional and administrative conditions, such as budgeting and land concerns, which affect it. Building on the research project implemented by the China Academy for Cultural Heritage (CACH) from 2012–2014, which focused on the impact of the Dayizhi Policy for Great Archaeological Sites, the book provides an interdisciplinary insider’s approach to viewing archaeological discoveries; policies and emerging practices in site and archaeological management; and public administration in China. Featuring contributions from experts within CACH and from the Chinese community of archaeologists, and including numerous tables, data and maps, it will appeal to researchers and scholars in disciplines such as archaeology, heritage management, public administration, and policy making.
This book presents a novel framework design for the next generation Marine Wireless Communication Networks (MWCNs). The authors first provide an overview of MWCNs, followed by a discussion of challenges in the design and development of MWCNs in support of a diversity of marine services such as real-time marine monitoring, offshore oil exploration, drilling, marine tourism and fishing. The authors then propose cross layer networking solutions to achieve a high performance modern MWCN that enables efficient and reliable data transmissions under hostile marine environment, which include the network deployment, the physical layer channel coding, intelligent network access and resource management, and learning-based opportunistic routing. Finally, the authors summarize the book and present some open issues that will lead to new research directions in the next generation MWCNs.
