The author demonstrates to developers how to use the web service to build custom applications with interactive mapping abilities for the desktop, the Web, and for mobile devices.
Wireless cellular networks are an integral part of modern telecommunication systems. Today it is hard to imagine our life without the use of such networks. Nevertheless, the development, implementation and operation of these networks require engineers and scientists to address a number of interrelated problems. Among them are the problem of choosing the proper geometric shape and dimensions of cells based on geographical location, finding the optimal location of cell base station, selection the scheme dividing the total net bandwidth between its cells, organization of the handover of a call between cells, information security and network reliability, and many others. The book focuses on three types of problems from the above list - Positioning, Performance Analysis and Reliability. It contains three sections. The Section 1 is devoted to problems of Positioning and contains five chapters. The Section 2 contains eight Chapters which are devoted to quality of service (QoS) metrics analysis of wireless cellular networks. The Section 3 contains two Chapters and deal with reliability issues of wireless cellular networks. The book will be useful to researches in academia and industry and also to post-gradute students in telecommunication specialitiies.
The Connected City explores how thinking about networks helps make sense of modern cities: what they are, how they work, and where they are headed. Cities and urban life can be examined as networks, and these urban networks can be examined at many different levels. The book focuses on three levels of urban networks: micro, meso, and macro. These levels build upon one another, and require distinctive analytical approaches that make it possible to consider different types of questions. At one extreme, micro-urban networks focus on the networks that exist within cities, like the social relationships among neighbors that generate a sense of community and belonging. At the opposite extreme, macro-urban networks focus on networks between cities, like the web of nonstop airline flights that make face-to-face business meetings possible. This book contains three major sections organized by the level of analysis and scale of network. Throughout these sections, when a new methodological concept is introduced, a separate ‘method note’ provides a brief and accessible introduction to the practical issues of using networks in research. What makes this book unique is that it synthesizes the insights and tools of the multiple scales of urban networks, and integrates the theory and method of network analysis.

For Mackenzie, entanglements with things, gadgets, infrastructures, and services---tendencies, fleeting nuances, and peripheral shades of often barely registered feeling that cannot be easily codified, symbolized, or quantified---mark the experience of wirelessness, and this links directly to James's expanded conception of experience. "Wirelessness" designates a tendency to make network connections in different times and places using these devices and services. Equally, it embodies a sensibility attuned to the proliferation of devices and services that carry information through radio signals. Above all, it means heightened awareness of ongoing change and movement associated with networks, infrastructures, location, and information. --

The book departs from the approach of related titles by focusing on describing and reflecting upon the notion of seamless learning with regard to salient characteristics of learner mobility and bridging of learning experiences across learning spaces. It is the first such work that is solely dedicated to research on and the practice of seamless learning, uniquely combining interpretations, visions, and past research on and practices in seamless learning from diversified perspectives. The book also strikes a good balance between theoretical and practical perspectivess, going beyond a collection of reports on specific research projects. Instead of thick descriptions of research processes and findings, readers will find significant insights and food for thought intended to inspire further advances in the research on and practice of seamless learning.
