Inspection and Monitoring Technologies of Transmission Lines with Remote Sensing helps readers build a thorough understanding of new technologies and world-class practices developed by the State Grid Corporation of China-the organization responsible for the world's largest power distribution network. Monitoring the operational status of high-voltage transmission lines is critical in supply assurance and continuity. Given the physical size, geographical, and climate variances that transmission lines are subject to, remote sensing and inspection is a critical technology for power distribution organizations. This reference covers current and developing technologies, equipment, and methods for the safe and secure operation and maintenance of transmission lines, including satellite remote sensing technology, infrared and ultraviolet detection technology, helicopter inspection technology, and condition monitoring technology.

This book presents developments and new results on complex differential-difference equations, an area with important and interesting applications, which also gathers increasing attention. Key problems, methods, and results related to complex differential-difference equations are collected to offer an up-to-date overview of the field.

This book describes a variety of highly effective and efficient structure-preserving algorithms for second-order oscillatory differential equations. Such systems arise in many branches of science and engineering, and the examples in the book include systems from quantum physics, celestial mechanics and electronics. To accurately simulate the true behavior of such systems, a numerical algorithm must preserve as much as possible their key structural properties: time-reversibility, oscillation, symplecticity, and energy and momentum conservation. The book describes novel advances in RKN methods, ERKN methods, Filon-type asymptotic methods, AVF methods, and trigonometric Fourier collocation methods.  The accuracy and efficiency of each of these algorithms are tested via careful numerical simulations, and their structure-preserving properties are rigorously established by theoretical analysis. The book also gives insights into the practical implementation of the methods. This book is intended for engineers and scientists investigating oscillatory systems, as well as for teachers and students who are interested in structure-preserving algorithms for differential equations.

This book constitutes the refereed proceedings of the 13th China Conference on Wireless Sensor Networks, CWSN 2019, held in Chongqing, China, in October 2019.

The 27 full papers were carefully reviewed and selected from 158 submissions. The papers are organized in topical sections on fundamentals on Internet of Things; applications on Internet of Things; and IntelliSense, location and tracking.
