This book provides readers with detailed explanation of the design principles of CMOS integrated circuits for wireless medical and health care, from the perspective of two successfully-commercialized applications. Design techniques for both the circuit block level and the system level are discussed, based on real design examples. CMOS IC design techniques for the entire signal chain of wireless medical and health care systems are covered, including biomedical signal acquisition, wireless transceivers, power management and SoC integration, with emphasis on ultra-low-power IC design techniques.

This book explores the transformative methods that have revolutionized underwater robotics in recent decades. Focusing on practical algorithms and real-world applications, this book fulfills the pressing need for a comprehensive resource on underwater acoustic-optical perception. Highlighting advanced techniques such as Transformer models for sonar object tracking and detection, the ℓ1-total variation model, and acoustic-optical fusion, this book provides an in-depth exploration of sonar image processing, object detection, and tracking while addressing emerging challenges and future research directions. Rich with illustrative examples and computational case studies, this book serves as an essential reference for diverse audiences. University students pursuing underwater information processing and engineers specializing in deep-sea exploration, subsea operations, and sonar data analysis find it particularly invaluable. By bridging foundational concepts with cutting-edge innovations, this book offers the tools and insights necessary to advance understanding and implementation in underwater robotics and perception systems.

What does it mean to a family when parents go abroad for economic gains while leaving their children behind? How do they maintain a family when living in different areas, separated for years? How do emerging digital media like instant messaging, social media, and webcam calls impact the everyday lives of today’s transnational families? Drawing on immersive ethnography conducted among UK-based Chinese labour migrants, their left-behind children and caregivers, this book explores how they employ digital media to negotiate family roles and maintain kinship ties. While virtual connections are indispensable, they are not a panacea for physical separation; rather, they introduce complexity to family dynamics. Probing the bittersweet experiences of various family members, it portrays how mediated familial communications intertwine with transnational socio-economic asymmetries and intra-familial dynamics. This book offers an interdisciplinary perspective for general publics and academics interested in migration studies, family and gender studies, and media and communications.

This book benefits those interested in space tourism for doing business, conducting research, and teaching space services. The value chain analysis approach is applied to construct the knowledge system of the space industry from suppliers, consumers, agents, and related stakeholders. Space tourism has made a breakthrough in travel boundaries beyond Kármán line and impacted human living in many aspects, especially a vision of Mars immigration. The tourism industry has extended its reach to outer space. Space education has been popular in many countries because of human capital to serve in the new field. Researchers have developed unique methodologies to study space economic behaviors. The advancements in space technology and commercialization have formed a new market to drive a new era of space economics. Individuals can now venture beyond the Kármán line and fulfill their desire for space exploration through space tourism. This form of tourism offers a unique opportunity for individuals to explore the origins and limitations of human beings. This book provides an overview of the current state of global space tourism development, including its characteristics, direct and indirect stakeholders, and existing challenges. The successful implementation of space tourism cases by private enterprises in Europe and the USA offers valuable insights into China's space tourism endeavors. Given China's leading position in global space technology, space tourism represents a promising commercial development field that can benefit the country and its citizens.

The dragon is the incarnation of the Chinese ancestors, the phoenix is the ideal for the nation to fly. Dragon and phoenix are the totems of the Chinese nation. Dragon and Phoenix Harbingering Prosperity symbolizes the Chinese nation's journey of formation in its diversity and unity, embodies the Chinese culture's strength in its combination of vigor and suppleness and the harmony of yin and yang, and symbolizes the advent of a peaceful and prosperous world. With dragons flying and phoenixes dancing, Chinese culture is one of unremitting strive for self-improvement. It is characterised by its submerged and ascending nature, its longevity and daily renewal; it features a simple and delicate structure, one that is balanced and versatile; it has a majestic and elegant spirit, one that is moderate and vigorous. Let's talk about dragons and phoenixes and enter the beautiful hall of Chinese culture.

Nonlinear Estimation and Control of Automotive Drivetrains discusses the control problems involved in automotive drivetrains, particularly in hydraulic Automatic Transmission (AT), Dual Clutch Transmission (DCT) and Automated Manual Transmission (AMT). Challenging estimation and control problems, such as driveline torque estimation and gear shift control, are addressed by applying the latest nonlinear control theories, including constructive nonlinear control (Backstepping, Input-to-State Stable) and Model Predictive Control (MPC). The estimation and control performance is improved while the calibration effort is reduced significantly. The book presents many detailed examples of design processes and thus enables the readers to understand how to successfully combine purely theoretical methodologies with actual applications in vehicles. The book is intended for researchers, PhD students, control engineers and automotive engineers. Hong Chen is a professor at the State Key Laboratory of Automotive Simulation and Control, and the Department of Control Science and Engineering at Jilin University. Bingzhao Gao is an associate professor at the State Key Laboratory of Automotive Simulation and Control at Jilin University.

The objective of this book is to collect in a single volume the essentials of stochastic networks, from the classical product-form theory to the more re­ cent developments such as diffusion and fluid limits, stochastic comparisons, stability, control (dynamic scheduling) and optimization. The selection of materials inevitably is a reflection upon our bias and preference, but it is also driven to a large extent by our desire to provide a graduate-level text that is well balanced in breadth and depth, suitable for the classroom. Given the wide-ranging applications of stochastic networks in recent years, from supply chains to telecommunications, it is also our hope that the book will serve as a useful reference for researchers and students alike in these diverse fields. The book consists of three parts. The first part, Chapters 1 through 4, covers (continuous-time) Markov-chain models, including the classical Jackson and Kelly networks, the notion of quasi-reversible queues, and stochastic comparisons. The second part, Chapters 5 through 10, focuses on Brownian models, including limit theorems for generalized Jackson net­ works and multiclass feedforward networks, an in-depth examination of stability in a Kumar-Seidman network, and Brownian approximations for general multiclass networks with a mixture of priority and first-in-first-out disciplines. The third part, Chapters 11 and 12, discusses scheduling in both queueing (stochastic) and fluid (deterministic) networks, along with topics such as conservation laws, polymatroid optimization, and linear pro­ gramming.
