NG-RAN and 5G-NR describes the deployment of 5G NSA (non standalone 5G) and 5G-SA (standalone 5G). 5G-NSA deals with radio access entities. For the 5G-NSA mode, dual MR DC connectivity is based on radio measurements, allowing the master 4G base station MeNB to add or remove a secondary 5G node SgNB. This book describes the architecture of the NG radio access network and the 5G-NR radio interface according to the 3GPP (3rd Generation Partnership Project) specifications. The overall architecture of the NG-RAN, including the NG, Xn and F1 interfaces and their interaction with the radio interface, are also described. The 5G-NR physical layer is mainly connected by implementing antennas, which improves transmission capacity. 5G-SA deals with the 5G Core network. In the 5G-SA model, the mobile is attached to the 5G Core network through NG-RAN. The book explains radio procedure, from switching on a device to establishing a data connection, and how this connection is maintained even if mobility is involved for both 5G-SA and 5G-NSA deployment. NG-RAN and 5G-NR is devoted to the radio access network, but mobile registration, establishment procedures and re-establishment procedures are also explained.

The challenges associated with the environmental impact of renewable energies are formidable and multiple. The exploitation of diffuse forms of energy will require us to reshape our lifestyles and infrastructures. Reducing their environmental impact is imperative and requires the mobilization of all available levers of action. Beyond the analysis of these challenges, this book presents an overview of the levers of action that should allow us to meet them, by crossing the fields of the human sciences, geosciences and engineering. The levers of action examined are both technical (through the substitution or use of low technology) and economic and social (through the development of recycling or decoupling). The book also addresses the question of their effectiveness and their overall impact.
The shadowing function is an important element in the simulation and calculation of how electromagnetic waves scatter at randomly rough surfaces. Its derivation and use is an active, interdisciplinary area of research with practical applications in fields such as radar, optics, acoustics, geoscience, computer graphics and remote sensing. This book addresses the general problem of the derivation of the shadowing function from randomly rough surfaces. The authors present an overview of theory and advances of this topic by detailing recent progress. Firstly, the simpler problems are investigated (monostatic case - 1D surface - one reflection) progressing in difficulty to more complicated problems (bistatic case - 2D surface - multiple reflections). In addition, the authors focus on the introduction of the simplifying assumptions to derive closed-form expressions of the shadowing function and quantify their impact on the accuracy of the resulting models. Applications of the shadowing function in problems encountered in physics are also addressed. The problem of the derivation of the shadowing function from a rough surface is at the boundary between several scientific communities, each with its terminology. This book makes the link between these different communities and will help the reader to understand the theoretical aspects of this problem while giving practical applications.
An introduction to machine learning methods and their applications to problems in bioinformatics Machine learning techniques are increasingly being used to address problems in computational biology and bioinformatics. Novel computational techniques to analyze high throughput data in the form of sequences, gene and protein expressions, pathways, and images are becoming vital for understanding diseases and future drug discovery. Machine learning techniques such as Markov models, support vector machines, neural networks, and graphical models have been successful in analyzing life science data because of their capabilities in handling randomness and uncertainty of data noise and in generalization. From an internationally recognized panel of prominent researchers in the field, Machine Learning in Bioinformatics compiles recent approaches in machine learning methods and their applications in addressing contemporary problems in bioinformatics. Coverage includes: feature selection for genomic and proteomic data mining; comparing variable selection methods in gene selection and classification of microarray data; fuzzy gene mining; sequence-based prediction of residue-level properties in proteins; probabilistic methods for long-range features in biosequences; and much more. Machine Learning in Bioinformatics is an indispensable resource for computer scientists, engineers, biologists, mathematicians, researchers, clinicians, physicians, and medical informaticists. It is also a valuable reference text for computer science, engineering, and biology courses at the upper undergraduate and graduate levels.
Electric vehicles are changing transportation dramatically and this unique book merges the many disciplines that contribute research to make EV possible, so the reader is informed about all the underlying science and technologies driving the change. An emission-free mobility system is the only way to save the world from the greenhouse effect and other ecological issues. This belief has led to a tremendous growth in the demand for electric vehicles (EV) and hybrid electric vehicles (HEV), which are predicted to have a promising future based on the goals fixed by the European Commission's Horizon 2020 program. This book brings together the research that has been carried out in the EV/HEV sector and the leading role of advanced optimization techniques with artificial intelligence (AI). This is achieved by compiling the findings of various studies in the electrical, electronics, computer, and mechanical domains for the EV/HEV system. In addition to acting as a hub for information on these research findings, the book also addresses the challenges in the EV/HEV sector and provides proven solutions that involve the most promising AI techniques. Since the commercialization of EVs/HEVs still remains a challenge in industries in terms of performance and cost, these are the two tradeoffs which need to be researched in order to arrive at an optimal solution. Therefore, this book focuses on the convergence of various technologies involved in EVs/HEVs. Since all countries will gradually shift from conventional internal combustion (IC) engine-based vehicles to EVs/HEVs in the near future, it also serves as a useful reliable resource for multidisciplinary researchers and industry teams.
We all enjoy the benefits of the 'information age' but we may not be aware of the range of technologies and infrastructure that underpins the Internet and the services that it supports. There are many companies involved in the business of providing and operating such resources. This book attempts to explain the complex interplay between the companies, how their businesses operate, and how they seek to make a profit. The authors consider how telecommunications companies tackle the challenging Information and Communication Technology market place - how they make a case for investment, develop and market products, and how they operate telecommunications networks and computer-server resources. Topics covered include: an introduction to the telecommunications business; regulation; business strategy; corporate finance and governance; network economics; network strategy and planning; customers and marketing; product management; network and service operations; and people and organisation development. In particular, this book provides a comprehensive introduction to the tools for analysing markets, constructing business cases and providing customer service - all with specific reference to telecommunications and reallife case studies. The authors have based this book on the material used to teach Masters Degree students over the last 10 years, as well as drawing on their knowledge gained through a combined experience of over 80 years working within the industry. Understanding Telecommunications Business is essential for undergraduate and graduate students studying telecommunications, and will also find a place on the bookshelves of the many people already working in the industry, or considering joining it. Although selfcontained, this book forms a companion to Understanding Telecommunications Networks, which is also in the IET Telecommunications series.
