本书简明而通俗地介绍了化学在生活中的应用，没有空洞枯燥的化学概念，没有繁琐的化学方程式，没有元素周期表，更没有抽象难理解的化学理论，它通过用浅显的化学原理分析我们生活中的实例，使我们掌握如何运用化学来解决生活中的难题。它没有用抽象的文字和枯燥的概念告诉我们什么是应用化学，而是运用通俗的语言探究应用化学在我们日常生活中所发挥的作用。本书内容从简单到复杂，从浅显到深入，从表面现象到内部原因，通过阅读让你明白 生活其实很简单，化学不只存在于书本中，生活中处处离不开化学，化学渗透到我们生活的每一个细节。

生活中的趣味化学是由上海市青少年科技教学中心化学教研室编写的一本以生活中的化学知识为切入点，让学生了解新科技，如奥运火炬、安全气囊等，与学生生活密切相关的，如食品卫生、卫生保健、能源与材料、环境保护等，全书共分十章，本书作为上海市九年级学生"白猫杯"化学竞赛的指定用书，也可以作为广大中小学生的科普读物。有趣的故事，人人爱听;趣味小实验，人人喜欢做。本书以故事和趣味小实验形式为大家呈现精彩纷呈的化学世界。为了使你对本书有个感性认识，先讲三个有趣的小故事。

Driven by the increasing demand for capacity and Quality of Service in wireless cellular networks and motivated by the distributed antenna system, the authors proposed a cooperative communication architecture-Group Cell architecture, which was initially brought forward in 2001. Years later, Coordinated Multiple-Point Transmission and Reception (CoMP) for LTE-Advanced was put forward in April 2008, as a tool to improve the coverage of cells having high data rates, the cell-edge throughput and/or to increase system throughput. This book mainly focuses on the Group Cell architecture with multi-cell generalized coordination, Contrast Analysis between Group Cell architecture and CoMP, Capacity Analysis, Slide Handover Strategy, Power Allocation schemes of Group Cell architecture to mitigate the inter-cell interference and maximize system capacity and the trial network implementation and performance evaluations of Group Cell architecture.

This SpringerBrief presents research results on QoE management schemes for mobile services, including user services, and resource allocation. The primary focus is on introducing efficient personalized character extraction mechanisms, e.g., context-aware Bayesian graph model, and cooperative QoE management mechanisms.

This book describes kaleidoscopic topics that have developed in the area of graph colorings. Unifying current material on graph coloring, this book describes current information on vertex and edge colorings in graph theory, including harmonious colorings, majestic colorings, kaleidoscopic colorings and binomial colorings.

A comprehensive treatment of color-induced graph colorings is presented in this book, emphasizing vertex colorings induced by edge colorings. This gives rise to a discussion of irregular colorings, strong colorings, modular colorings, edge-graceful colorings, twin edge colorings and binomial colorings.

This monograph offers a detailed analysis of the creation, pilot implementation, and possible wide adoption of the real property tax at the local level in China.

a

Offers the research by a set of authors who span the MIS and HCI fields. This book focuses on the basics of HCI, with emphasis on concepts, issues, theories, and models that are related to understanding human tasks, and the interactions among humans, tasks, information, and technologies in organizational contexts in general.

Based on a course entitled 'Wigner measures and semiclassical limits of nonlinear Schrodinger equations,' this book applies the theory of semiclassical pseudodifferential operators to the study of various high-frequency limits of equations from quantum mechanics.

This brief examines the current research in cognitive wireless networks (CWNs). Along with a review of challenges in CWNs, this brief presents novel theoretical studies and architecture models for CWNs, advances in the cognitive information awareness and delivery, and intelligent resource management technologies.
