Description : This new and updated second edition of a classic text provides a thought provoking introduction to metadata for all library and information students and professionals. Metadata for Information Management and Retrieval has been fully revised to bring it up to date with new technologies and standards. It builds on the concept of metadata through an exploration of its purposes and uses as well as considering the main aspects of metadata management. This new edition, containing new chapters on ‘Very Large Data Collections’ and the ‘Politics and Ethics of Metadata’, assesses the current theory and practice of metadata and examines key developments in terms of both policy and technology. Coverage includes: defining, describing and expressing metadatadata modellingmetadata and information retrievalbig data, linked data, and social mediaresearch data collections and open data repositoriesmetadata in information governance: compliance, risk and information securitymanaging intellectual property rightsthe politics of metadata: ethics, power and money. This book is essential reading for library and information students at undergraduate and postgraduate level and will also be useful reading for LIS professionals looking for an accessible introduction to metadata.
Description : Detailing a systems approach, Optical Wireless Communications: System and Channel Modelling with MATLAB®, is a self-contained volume that concisely and comprehensively covers the theory and technology of optical wireless communications systems (OWC) in a way that is suitable for undergraduate and graduate-level students, as well as researchers and professional engineers. Incorporating MATLAB® throughout, the authors highlight past and current research activities to illustrate optical sources, transmitters, detectors, receivers, and other devices used in optical wireless communications. They also discuss both indoor and outdoor environments, discussing how different factors—including various channel models—affect system performance and mitigation techniques. In addition, this book broadly covers crucial aspects of OWC systems: Fundamental principles of OWC Devices and systems Modulation techniques and schemes (including polarization shift keying) Channel models and system performance analysis Emerging visible light communications Terrestrial free space optics communication Use of infrared in indoor OWC One entire chapter explores the emerging field of visible light communications, and others describe techniques for using theoretical analysis and simulation to mitigate channel impact on system performance. Additional topics include wavelet denoising, artificial neural networks, and spatial diversity. Content also covers different challenges encountered in OWC, as well as outlining possible solutions and current research trends. A major attraction of the book is the presentation of MATLAB simulations and codes, which enable readers to execute extensive simulations and better understand OWC in general.
Description : For the readers of The Language of God, another instant classic from "a sophisticated and original scholar" (Kirkus Reviews) that disputes the idea that science is contrary to religion. In The Science of God, distinguished physicist and Biblical scholar Gerald L. Schroeder demonstrates the surprising parallels between a variety of Biblical teachings and the findings of biochemists, paleontologists, astrophysicists, and quantum physicists. In a brilliant and wide-ranging discussion of key topics that have divided science and religion—free will, the development of the universe, the origin of life, and the origin of man—Schroeder argues that the latest science and a close reading of the Bible are not just compatible but interdependent. This timely reissue of The Science of God features a brand-new preface by Schroeder and a compelling appendix that addresses the highly publicized experiment in 2008 in which scientists attempted to re-create the chemical composition of the cosmos immediately after the Big Bang. It also details Schroeder’s lucid explanations of complex scientific and religious concepts, such as the theory of relativity, the passage of time, and the definitions of crucial Hebrew words in the Bible. Religious skeptics, Biblical literalists, scientists, students, and physicists alike will be riveted by Schroeder’s remarkable contribution to the raging debate between science and religion.
Description : Written by two professionals with differing perspectives, this text covers both research and practice. It offers basic how-to information on the use of such systems, covers topics and issues for which there are no accepted paradigms, and discusses alternative points of view within a framework of previous research. Designed to assist beginning searchers, the text covers online systems that primarily provide information in the form of bibliographic citations.
