Location-based Services (LBSs) are mobile services for providing information that has been created, compiled, selected or filtered under consideration of the users’ current locations or those of other persons or mobile devices. Typical examples are restaurant finders, buddy trackers, navigation services or applications in the areas of mobile marketing and mobile gaming. The attractiveness of LBSs is due to the fact that users are not required to enter location information manually but are automatically pinpointed and tracked.
This book explains the fundamentals and operation of LBSs and gives a thorough introduction to the key technologies and organizational procedures, offering comprehensive coverage of positioning methods, location protocols and service platforms, alongside an overview of interfaces, languages, APIs and middleware with examples demonstrating their usage.
Explanation and comparison of all protocols and architectures for location services
In-depth coverage of satellite, cellular and local positioning
All embracing introduction to 3GPP positioning methods, such as Cell-Id, E-OTD, U-TdoA, OTDoA-IPDL and Assisted GPS

As pop culture, games are as important as film or television--but game design has yet to develop a theoretical framework or critical vocabulary. In Rules of Play Katie Salen and Eric Zimmerman present a much-needed primer for this emerging field. They offer a unified model for looking at all kinds of games, from board games and sports to computer and video games. As active participants in game culture, the authors have written Rules of Play as a catalyst for innovation, filled with new concepts, strategies, and methodologies for creating and understanding games.. Building an aesthetics of interactive systems, Salen and Zimmerman define core concepts like "play," "design," and "interactivity." They look at games through a series of eighteen "game design schemas," or conceptual frameworks, including games as systems of emergence and information, as contexts for social play, as a storytelling medium, and as sites of cultural resistance. Written for game scholars, game developers, and interactive designers, Rules of Play is a textbook, reference book, and theoretical guide. It is the first comprehensive attempt to establish a solid theoretical framework for the emerging discipline of game design.

Fundamentals of OOP and Data Structures in Java presents the fundamentals of Object-Oriented Programming (OOP) and Graphical User Interface (GUI) programming with Java as the example language. Wiener and Pinson introduce each of the major data structures with supporting, GUI-based laboratory programs designed to reinforce the basic concepts and principles. These laboratories allow the reader to explore and experiment with the properties of each data structure. All source code for the laboratories is available on the Web. By integrating the principles of OOP and GUI programming, this unique book presents the fundamental issues of data structures within the context of paradigms that are essential to today's professional software developer. The text assumes only an elementary understanding of Java and no experience with OOP.
