Satellite images acquired at night provide a visually arresting perspective of the Earth and the human activities that light up the otherwise mostly dark Earth. These night-time light satellite images can be compiled into a geospatial time series that represent an invaluable source of information for both the natural and social sciences. Night-time light remote sensing has been shown to be particularly useful for a range of natural science and social science applications, including studies relating to urban development, demography, sociology, fishing activity, light pollution and the consequences of civil war. Key sensors for these time-series include the Defense Meteorological Satellite Program’s Operational Linescan System (DMSP/OLS) and the Suomi National Polar-orbiting Partnership Satellite’s Visible Infrared Imaging Radiometer Suite Day/Night Band (Suomi NPP/VIIRS DNB). An increasing number of alternative sources are also available, including high spatial resolution and multispectral sensors.This book captures key methodological issues associated with pre-processing night-time light data, documents state of the art analysis methods, and explores a wide range of applications. Major sections focus on NPP/VIIRS DNB processing; inter-calibration between NPP/VIIRS and DMPS/OLS; applications associated with socio-economic activities, applications in monitoring urbanization; and fishing activity monitoring. The chapters in this book were originally published as a special issue of the International Journal of Remote Sensing.

This book examines the presence and patterns of posttraumatic growth in selected biblical texts in the Hebrew Bible/Old Testament to show how ancient Israelites interpreted trauma, particularly the fall of Jerusalem, and how these responses reshape biblical interpretation and theology.It offers a reflection on the theological and psychological implications of trauma in the Bible, ultimately encouraging a positive approach to personal suffering and crises. In the first chapter, Li argues for the qualified applicability of today’s psychological research to ancient people. The following chapters examine these questions in specific biblical texts: whether a traumatic event is described in the text; whether and what dimension of posttraumatic growth is presented; whether growth coexists with stress after the traumatic events; and whether posttraumatic growth is accompanied by the belief in a just world and the form it takes. This book reveals some crucial features of posttraumatic growth in ancient Israel, leads to a fresh interpretation of biblical texts, and helps readers to understand ancient Israelites’ unique worldview and faith.Posttraumatic Growth in Psalms of Lament, Jeremiah, and Lamentations is suitable for students and scholars in biblical studies, especially those interested in psychological and trauma-informed reading of the Bible and the relationship between scripture, trauma, and suffering.

The ebook edition of this title is Open Access and freely available to read online.While the 5th Generation (5G) system is being widely deployed across the globe, the research and consensus building for the 6th generation (6G) are already well underway with high expectations toward the merger of digital, physical and human worlds. The main goal of this book is to introduce the upcoming 6G technologies and outline the foreseen challenges, enablers, and architectural design trends that will be instrumental in realizing a Sustainable and Trustworthy 6G system in the coming years.The envisioned 6G system promises to offer a more advanced and comprehensive user experience not only by achieving higher speeds, larger capacity, and lower latency, but also much more improved reliability, greater energy efficiency, and an enhanced security framework while natively integrating intelligence end-to-end (E2E). Achieving these goals will require innovative technological solutions and a holistic system design that considers the needs of various stakeholders and future 6G use cases.Capitalizing on the 5G Public-Private-Partnership (5G PPP) Phase 3 projects and the join efforts between the Architecture Working Group and the flagship Hexa-X project, this book delves into the critical challenges and enablers of the 6G system, including new network architectures and novel enhancements as well as the role of regulators, network operators, industry players, application developers, and end-users. Accordingly, this book provides a comprehensive overview of the current research activities on 6G and sets a solid cornerstone towards a more connected, intelligent, and sustainable world.

This is the first book to introduce UUDN for 5G, including the concept, challenges, architecture and key technologies.The new network architecture based on “de-cellular” and “user-centric” is proposed with three kinds of decoupling: user plane and control plane decoupling from radio access, control and transmission decoupling from network, local service and network service decoupling.Key characteristics of UUDN are provided, including four aspects: Intelligent network knows user, Moving network follows user, Dynamic network serves user, and Secured network protects user.Four promising technology directions are discussed in detail, including dynamic APs grouping (DAPGing) method, intelligent networking, advanced interference management and user-centric security.The authors also include a UUDN solution, illustrated with numerology and evaluation results as a practical example. Finally, further research directions of UUDN are analyzed.This book gives an overall introduction of UUDN for people who are interested and just begin their study, as well as some suggestions on further research for experts involved in academic, industrial and standardization activities on relative fields.

Xi Li presents innovative analytical models and algorithms for the dimensioning of the 3G UMTS Radio Access Network (RAN). The proposed analytical models allow efficient and accurate dimensioning for different evolutions of UMTS radio access technologies.
