Modern geochemistry possesses not only the vigor of geology and chemistry but also the rigor of mathematics. This book presents quantitative treatments of a wide range of fundamental problems related to geochemistry and geology. It shows that trace elements, isotopes, and equations are integrative tools in modern geochemistry for studying various Earth processes. In many chapters, simple models are presented first, and more parameters are gradually added so that the sophisticated models can be perceived as natural outgrowths of simple ones. The book will help scientists and graduate students in Earth Sciences improve their capacity to understand, apply, criticize, and appreciate the available models and possibly to develop their own models. This understanding will provide penetrating insights into fundamental principles in geochemistry, geology, analytical chemistry, and mass spectrometry as well as any other fields in the natural sciences./a
The three volume set LNCS 5551/5552/5553 constitutes the refereed proceedings of the 6th International Symposium on Neural Networks, ISNN 2009, held in Wuhan, China in May 2009.

The papers are organized in 20 topical sections on theoretical analysis, stability, time-delay neural networks, machine learning, neural modeling, decision making systems, fuzzy systems and fuzzy neural networks, support vector machines and kernel methods, genetic algorithms, clustering and classification, pattern recognition, intelligent control, optimization, robotics, image processing, signal processing, biomedical applications, fault diagnosis, telecommunication, sensor network and transportation systems, as well as applications.
Theory and Application of Multiphase Lattice Boltzmann Methods presents a comprehensive review of all popular multiphase Lattice Boltzmann Methods developed thus far and is aimed at researchers and practitioners within relevant Earth Science disciplines as well as Petroleum, Chemical, Mechanical and Geological Engineering. Clearly structured throughout, this book will be an invaluable reference on the current state of all popular multiphase Lattice Boltzmann Methods (LBMs). The advantages and disadvantages of each model are presented in an accessible manner to enable the reader to choose the model most suitable for the problems they are interested in. The book is targeted at graduate students and researchers who plan to investigate multiphase flows using LBMs. Throughout the text most of the popular multiphase LBMs are analyzed both theoretically and through numerical simulation. The authors present many of the mathematical derivations of the models in greater detail than is currently found in the existing literature. The approach to understanding and classifying the various models is principally based on simulation compared against analytical and observational results and discovery of undesirable terms in the derived macroscopic equations and sometimes their correction. A repository of FORTRAN codes for multiphase LBM models is also provided.
Identity and Schooling among the Naxi examines the identity construction of Naxi students in Lijiang No.1 Senior Secondary School in China, focusing on the changing roles of school, community, and family in the identity construction of the students. Through participant observation, interviews, and student essays, Yu finds that Naxi students of the school retain a strong Naxi identity while also managing to fit into mainstream culture through a process she characterizes as "harmonious creative identity engagement". Three main forces affecting the identity construction of the Naxi students are highlighted: the state and the school, Naxi intellectuals, and socialization in the family and community. As an institution of the state, the school conveys national ideology and instills a sense of ethnic unity and an understanding of the culture of the Chinese nation. However, the school also takes an active role in ethnic identity construction of the Naxi students. At the same time, Naxi intellectuals, through their research publications and responses to state policies, preserve and revitalize Naxi culture. Socialization within the community and family allows the Naxi students to learn about their heritage. These factors result in both an asserted and assigned identity of the Naxi.
This book focuses on ancient Chinese management thoughts, building a Chinese management theory system and defining the core concepts. Firstly, it systematically reviews the excellent management ideas in traditional Chinese culture from the perspective of modern management, summarizing the experience and wisdom of Chinese management in order to disseminate the ideas to global readers, and highlighting the soft power of Chinese culture. Secondly, based on the management practices of Chinese local enterprises, the book refines the Chinese management model, constructing a modern management theory system with Chinese characteristics to promote innovation and changes in global management theory.
This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature.A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle-to-infrastructure communications.This book offers useful insights into protocol design and inspires a new line of thinking in performance improvements for safety applications in vehicular networks. It is a valuable resource for professionals, researchers, or advanced-level students working in vehicular networks or quality of service.
In this timely book about the current state of research and practice of emergency management in China, the authors take as their basic premises that we now live in a risk society and that our collective ability to deal with disasters and their aftermath is more important than ever. Set within a multi-disciplinary framework that places risk, disaster and crisis, the three phases of emergency management, on an analytical continuum, and drawing on empirical data obtained through surveys, observations, and interviews, the study not only provides a thorough overview of recent progress in our theoretical understanding of the subject but also offers insights on how scientifically informed policies can improve the way emergency management is done in China.
Density Matrix Renormalization Group (DMRG)-based Approaches in Computational Chemistry outlines important theories and algorithms of DMRG-based approaches and explores their use in computational chemistry. Beginning with an introduction to DMRG and DMRG-based approaches, the book goes on to discuss the key theories and applications of DMRG, from DMRG for semi-empirical and ab-initio quantum chemistry, to DMRG in embedded environments, frequency spaces and quantum dynamics. Drawing on the experience of its expert authors, sections detail recent ideas and key developments, providing an up-to-date view of current developments in the field for students and researchers in quantum chemistry. - Provides an expertly-curated, consolidated overview of research in the field - Includes exercises that support learning and link theory to practice - Outlines key theories and algorithms for computational chemistry applications
