A one-stop desk reference for R&D engineers involved in communications engineering, this book will not gather dust on the shelf. It brings together the essential professional reference content from leading international contributors in the field. Material covers a wide scope of topics, including voice, computer, facsimile, video, and multimedia data technologies.

This book presents a comprehensive examination of care for older adults in diverse economic and geographical contexts through a collection of country and regional case studies.

This book not only clearly introduces the characteristics of various types of silk in different dynasties, but also analyzes the technological and humanistic values of Chinese silk, helping readers gain a better understanding of Chinese silk art, Chinese culture, and the origin and development of the Silk Road.

The COVID-19 pandemic underscored how unprepared we are for a public-health emergency of staggering proportions. And yet potentially graver health threats loom. The only way to prevent, prepare for, and manage these threats is by building resilient health systems to withstand shocks and improve health outcomes between crises.

Very few topics in global health have been as controversial as primary health care. In this book the authors explain what it takes to reimagine primary health care in the 21st century, an era of increased rapidly changing health care needs, population expectations, availability of financial and human resources, and digital technology.

The Eastern Europe and Central Asia region has the world's fastest-growing HIV epidemic. Although still concentrated, the epidemic has diversified, affecting several key populations in many countries. This change has increased the number of people in need, the ways the epidemic can spread, and the complexity of formulating an effective strategy to combat it. At the same time, international funding is insufficient to cover the growing need, and domestic plans to cover the funding gaps, in many cases, fall short. In this environment, the need to use data to make the best possible decisions about using available funds is essential. Tackling the World's Fastest-Growing HIV Epidemic tells the story of how, in 11 countries across Eastern Europe and Central Asia, small groups of decision-makers and experts came together to carry out innovative, groundbreaking analyses for each country. It details the steps these nations have taken to strengthen their HIV programs based on the findings while highlighting critical issues for the road ahead. In so doing, the book also shows the potential of what can be done with a mathematical model and how it can support real-life improvements in policy and more efficacious budget allocations. It is the record of a unique undertaking to improve public health investments that offers lessons for many communities.

The China Next Generation Internet (CNGI) was launched in 2003 as the initial IPv6 project in Mainland China and the largest pure IPv6 Internet in the world. Technically, the CNGI is capable of implementing network addressed based on real IPv6 source addresses, meaning that it can find real locations through a user's IP address. It is also capable of tunnel technology, which means running and using IPv4 applications in an IPv6 environment. China deployed IPv6 networks in conjunction with the 2008 Beijing Olympics and the 2010 World Expo in Shanghai. Based on the latest technology developed by China's next-generation Internet demonstration project, this book comprehensively analyzes next-generation Internet networking scenarios and typical networking solutions, offering a holistic description of the most up-to-date directions and typical technical solutions in Internet technology. It also discusses the China Broadband Strategy and its relationship with the next-generation Internet.

This is a monograph that gives a deep interpretation of the silk culture in ancient times and described the historical evolution of the clothes--basic elements of daily life, which all together displays the beauty of silk and the Silk Road.

This book introduces low-noise and low-power design techniques for phase-locked loops and their building blocks. It summarizes the noise reduction techniques for fractional-N PLL design and introduces a novel capacitive-quadrature coupling technique for multi-phase signal generation. The capacitive-coupling technique has been validated through silicon implementation and can provide low phase-noise and accurate I-Q phase matching, with low power consumption from a super low supply voltage. Readers will be enabled to pick one of the most suitable QVCO circuit structures for their own designs, without additional effort to look for the optimal circuit structure and device parameters.

This essential bundle featuring three definitive titles on wireless networking provides an in-depth, exhaustive, and invaluable asset to anyone working or studying in this rapidly evolving field. Wireless Communications and Networking provides comprehensive coverage of mobile wireless communication, wireless networks, and internetworking/4G technology in one volume with a good blend of fundamental theory and real-world concepts and problem solving methods. Wireless Networking serves as a one-stop view of cellular, WiFi, and WiMAX networks, as well as the emerging wireless ad hoc and sensor networks. The book emphasizes conceptual perspectives on modeling, analysis, design and optimization and presents wireless networking within the framework of resource allocation. Designing, implementing, and operating a wireless sensor network involves a wide range of disciplines and many application-specific constraints. To make sense of and take advantage of these systems, a holistic approach is needed—and this is precisely what Wireless Sensor Networks delivers. Bundled together to save you money, there is no quicker or cheaper way to such a comprehensive knowledge of wireless networking.
