This accessible and timely book collects in a single volume the essentials of stochastic networks, from the classical product-form theory to the more recent developments such as diffusion and fluid limits, stochastic comparisons, stability, control (dynamic scheduling) and optimization.The book was developed from the authors' teaching stochastic networks over many years. It will be useful to students from engineering, business, mathematics, and probability and statistics. As stochastic networks have become widely used as a basic model of many physical systems in a diverse range of fields, the book can also be used as a reference or supplementary readings for courses in operations research, computer systems, communication networks, production planning and logistics, and by practitioners in the field.

Covers the latest practices, challenges and theoretical advancements in the domain of balancing economic efficiency and operation risk mitigation This book examines both system operation and market operation perspectives, focusing on the interaction between the two. It incorporates up-to-date field experiences, presents challenges, and summarizes the latest theoretic advancements to address those challenges. The book is divided into four parts. The first part deals with the fundamentals of integrated system and market operations, including market power mitigation, market efficiency evaluation, and the implications of operation practices in energy markets. The second part discusses developing technologies to strengthen the use of the grid in energy markets. System volatility and economic impact introduced by the intermittency of wind and solar generation are also addressed. The third part focuses on stochastic applications, exploring new approaches of handling uncertainty in Security Constrained Unit Commitment (SCUC) as well as the reserves needed for power system operation. The fourth part provides ongoing efforts of utilizing transmission facilities to improve market efficiency, via transmission topology control, transmission switching, transmission outage scheduling, and advanced transmission technologies. Besides the state-of-the-art review and discussion on the domain of balancing economic efficiency and operation risk mitigation, this book: Describes a new approach for mass market demand response management, and introduces new criteria to improve system performance with large scale variable generation additionsReviews mathematic models and solution methods of SCUC to help address challenges posed by increased operational uncertainties with high-penetration of renewable resourcesPresents a planning framework to account for the value of operational flexibility in transmission planning and to provide market mechanism for risk sharingPower Grid Operations in a Market Environment: Economic Efficiency and Risk Mitigation is a timely reference for power engineers and researchers, electricity market traders and analysts, and market designers.

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.

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.

This book systematically presents a use-wear analysis of quartzite stone artifacts from the Chinese Paleolithic archaeological record. It provides raw data and images from experimental and archaeological studies, building a comprehensive reference for international archaeologists to understand lithic reduction technology and utilization of quartzite tools by prehistorical humans, and offers an in-depth interpretation of human adaptative strategies and behavior patterns. In addition, this book shows an example of a theory-driven case study that demonstrates the significance and application of computer science techniques in archaeological research, such as data mining and cluster analysis to establish meaningful connections between material  and remains and behavioral information.

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.
