Focusing on the economics of telecommunication services, this textbook offers an engineering perspective that emphasizes the industry's fundamental drivers and network characteristics through graph theory. It explores the relationship between network topology and performance metrics, proposing a pricing model based on displaced opportunity costs. Additionally, it covers regulation, net neutrality, and the application of game theory in competitive markets. Aimed at senior undergraduates and graduate students, it bridges the gap between economic theory and telecommunications practice.

Focusing on the Qing-Tibetan interactions of the eighteenth century, this book explores the concept of "a unity with diversity" within the Qing imperial formation from 1636 to 1912. It examines how these encounters shaped the dynamics of power, culture, and identity, providing insights into the complexities of imperial rule and the relationships between different ethnic and cultural groups during this period.

Focusing on the practices of a Zen Buddhist temple in Northwest Ohio, this book examines the intersection of Buddhism and Western culture amid globalization. Utilizing rhetorical criticism, the author analyzes various forms of Buddhist expression, including teachings, online presence, and physical artifacts, to reveal how these elements shape and negotiate the community's religious identity. The work not only enhances understanding of modern Buddhist practices but also proposes a new methodology for studying religious identity, with implications for other faiths as well.

This book addresses three important issues in VoIP networks: Quality of Service, pricing and security.In addressing Quality of Service (QoS), it introduces the notion of delay not exceeding an upper limit, termed the bounded delay, to measure the Quality of Service in VoIP networks.

Side channel pump is a kind of radial vane pump and can be understood as a combination of a positive displacement pump and centrifugal pump. It is entitled in this way because this pump has a side channel on the axial side of the impeller. In recent years, side channel pumps are receiving increasing attention due to the high demand for lower specific pumps. As a regenerative pump, the head of the side channel pump increases many times among the radial impellers. However, the separate study on suction side blade profile is hardly seen in the open references. How to design a side channel pump with a better performance is still a challenging topic because of the complex flow inside the pump. This book conducts CFD-simulations on the flow and concludes that a vortex standing in the passage becomes weaker, if the triangular shape is applied. The numerical work was validated by the comparison between the simulated result and tested result. The author based its evaluation method on the exchanged mass flow which confirms that the performance of the side channel pump can be improved by increasing the angle on the suction side of the blade. This book extends the research to finding the ability of the side channel pumps to transport liquid with some gas inside. The side channel pumps are better used for gas-liquid transportation under some industrial conditions compared with other vane pumps. The blade suction angle greatly influences the hydraulic performance of the side channel pump, but studies on the effect of blade suction angle on the performance of this kind of pumps under two-phase flow operating condition have not been conducted yet. The author has presented an experimental investigation on the performance of side channel pumps under gas-liquid two-phase flow operating condition. The effect of inlet gas volume fraction (IGVF) on the performance of the side channel pump with three different blade suction angles are compared in detail. The experimental data obtained could serve as a design reference to two-phase flow side channel pumps. Lastly, the efficiency of the side channel pump is lower than other vane pumps such as centrifugal pumps and axial flow pumps. This effect is mainly caused by great losses inside the side channel pumps. Published references about where losses occur and its generation mechanism are also fewer because the losses always affect the hydraulic performance in pumps. The characteristics of the losses in side channel pump were investigated by the author calculating the entropy production in flow, in which the second law of thermodynamics was applied. The results in this thesis could be used to supply reference for designing better performance and wider applications of the side channel pumps.

This book introduces the latest advances made in both fundamental studies and potential applications of upconversion nanomaterials, particularly in the field of high-resolution in vitro bioanalysis and in vivo imaging. This book starts with the synthesis and characterization, and focuses on applications ranging from materials science to biology. Above all, it describes cutting-edge advances in upconversion nanophosphor (UCNP)-based applications in multiplexed encoding, guest delivery and release systems, photodynamic therapy (PDT), solar cells, photocatalysis and so on. The major barriers that currently prevent UCNPs from being used in mainstream applications are also presented in detail.

This book, as a volume of the Shock Wave Science and Technology Reference Library, is primarily concerned with the fundamental theory of detonation physics in gaseous and condensed phase reactive media. The detonation process involves complex chemical reaction and fluid dynamics, accompanied by intricate effects of heat, light, electricity and magnetism - a contemporary research field that has found wide applications in propulsion and power, hazard prevention as well as military engineering. The seven extensive chapters contained in this volume are: - Chemical Equilibrium Detonation (S Bastea and LE Fried) - Steady One-Dimensional Detonations (A Higgins) - Detonation Instability (HD Ng and F Zhang) - Dynamic Parameters of Detonation (AA Vasiliev) - Multi-Scaled Cellular Detonation (D Desbordes and HN Presles) - Condensed Matter Detonation: Theory and Practice (C Tarver) - Theory of Detonation Shock Dynamics (JB Bdzil and DS Stewart) The chapters are thematically interrelated in a systematic descriptive approach, though, each chapter is self-contained and can be read independently from the others. It offers a timely reference of theoretical detonation physics for graduate students as well as professional scientists and engineers.
