 This book is intended to describe how to leverage emerging technologies big data analytics and SDN, to address challenges specific to LTE and IP network performance and fault management data in order to more efficiently manage and operate an LTE wireless networks. The proposed integrated solutions permit the LTE network service provider to operate entire integrated network, from RAN to Core , from UE to application service, as one unified system and correspondingly collect and align disparate key metrics and data, using an integrated and holistic approach to network analysis. The LTE wireless network performance and fault involves the network performance and management of network elements in EUTRAN, EPC and IP transport components, not only as individual components, but also as nuances of inter-working of these components. The key metrics for EUTRAN include radio access network accessibility, retainability, integrity, availability and mobility. The key metrics for EPC include MME accessibility, mobility and capacity, SGW, PGW capacity and connectivity. In the first parts of the book, the authors  describe fundamental analytics techniques, and various key network partitions - RAN, Backhaul, Metro and Core of a typical LTE Wireless Service Provider Network. The second part of the book develops more advanced analytic techniques that can be used to solve complex wireless network problems. The second part of this book also describes practical and novel solutions for LTE service network performance and fault management systems using big data engineering. Self-organizing network (SON) architecture is presented as a way to utilize network performance and fault analytics to enable network automation. SON can significantly improve operational efficiencies and speed up network deployment. This book provides various ways to leverage data science to more intelligently and reliably to automate and manage a wireless network. The contents of the book should be useful to professional engineers and networking experts involved in LTE network operations and management. The content will also be of interest to researchers, academic and corporate, interested in the developments in fault analytics in LTE networks.

The oil–gas conductor is the key part that connects subsea facilities and offshore equipment. The installation, construction and the stability control in subsequent operation of the conductor are main technical problems in the field of offshore oil and gas engineering.

The book focuses on installation of oil and gas conductor in the offshore oil field. It includes three parts. The first part introduces the main installations and structural features of the wellhead above water and the wellhead under water. Then, it summarizes methods and theories of oil and gas conductor design. Finally, the differences in the construction techniques and supporting equipment of the three oil and gas well conductor installation methods are systematically described.

This book contains a complete set of equipment, construction process and design methods for oil and gas conductor installation with multidisciplinary knowledge of geotechnical engineering, civil engineering, and structural dynamics. Scientific researchers and college students engaged in marine oil and gas engineering, petroleum engineering, marine engineering will find this book as a valuable reference.
