Book Description
This book discusses recent technologies and case studies that aim to enhance positioning obtained with commercial smartphones in urban environments, overcoming difficulties with GPS. The authors provide insight into recent trends and innovation on technologies, solutions and approaches to overcome GPS issues in urban environments, due to the existence of a big number of buildings. Topics include security and legal aspects related to positioning systems, the usage of crowdsourcing approaches to enhance positioning, location-based services, proximity based-social networking, satellite navigation and Bluetooth low-energy based systems. The book provides important information for developers that intend to make use of precise positioning for the purpose of commercial applications as well as for research and innovation. Discusses technologies that enhance positioning obtained with commercial smartphones in urban environments; Presents innovations to overcome GPS issues in urban environments caused by dense cities; Includes applications of precise positioning, including their security issues and challenges.

Book Description
As part of the Physics 2010 decadal survey project, the Department of Energy and the National Science Foundation requested that the National Research Council assess the opportunities, over roughly the next decade, in atomic, molecular, and optical (AMO) science and technology. In particular, the National Research Council was asked to cover the state of AMO science, emphasizing recent accomplishments and identifying new and compelling scientific questions. Controlling the Quantum World, discusses both the roles and challenges for AMO science in instrumentation; scientific research near absolute zero; development of extremely intense x-ray and laser sources; exploration and control of molecular processes; photonics at the nanoscale level; and development of quantum information technology. This book also offers an assessment of and recommendations about critical issues concerning maintaining U.S. leadership in AMO science and technology.

Book Description
This book addresses the multiple technical aspects of the distribution of synchronization in new generation telecommunication networks, focusing in particular on synchronous Ethernet and IEEE1588 technologies. Many packet network engineers struggle with understanding the challenges that precise synchronization distribution can impose on networks. The usual “why”, “when” and particularly “how” can cause problems for many engineers. In parallel to this, some other markets have identical synchronization requirements, but with their own design requirements, generating further questions. This book attempts to respond to the different questions by providing background technical information. Invaluable information on state of-the-art packet network synchronization and timing architectures is provided, as well as an unbiased view on the synchronization technologies that have been internationally standardized over recent years, with the aim of providing the average reader (who is not skilled in the art) with a better understanding of this topic. The book focuses specifically on synchronous Ethernet and IEEE 1588 PTP-based technologies, both key developments in the world of synchronization over the last 10 years. The authors address the needs of engineers and technical managers who are struggling with the subject of synchronization and provide an engineering reference for those that need to consider synchronization in NGN. The market applications that are driving the development of packet network synchronization and timing architectures are also discussed. This book provides a wide audience with everything they need to know when researching, implementing, buying and deploying packet synchronization architectures in telecommunication networks.

Book Description
Radiometric Tracking Techniques for Deep-Space Navigation focuses on a broad array of technologies and concepts developed over the last four decades to support radio navigation on interplanetary spacecraft. In addition to an overview of Earth-based radio navigation techniques, the book includes a simplified conceptual presentation of each radiometric measurement type, its information content, and the expected measeurement accuracy. The methods described for both aquiring and calibrating radiometric measurements also provide a robust system to support guidance and navigation for future robotic space exploration.
