This book provides a systematical investigation on the reservoir characteristics and percolation mechanism of ultradeep carbonate gas reservoirs, including reservoir characteristics and classification, gas storage and percolation capacities, gas-phase and gas-water two-phase percolation mechanism, microscale complex gas-water relationship, reservoir sensitivity characteristics, and gas production characteristics of heterogeneous carbonate reservoirs. Some advanced and improved experimental techniques and analytical methods are introduced and applied, including comprehensive evaluation technique of storage and percolation capacities, ultra-high temperature and pressure physical simulation experiment technique, microscopic visualization technique based on CT scanning and microelectronics lithography, and physical simulation technique for heterogeneous reservoir development. In addition, it summarizes strategies for the efficient development of ultradeep carbonate gas reservoirs based on these theoretical research results. The key techniques and methods introduced in this monograph satisfy the need for efficient development of ultradeep carbonate gas reservoirs and provide theoretical basis and methodological value for investigations on similar gas reservoirs. This book serves as a reference for engineering technical professionals, researchers, and graduate students who are engaged in the exploration and development of carbonate gas reservoirs.

This book summarizes the technical method and construction process of pipe jacking. It has a total of 17 chapters and one appendix. It includes how to prepare the pipe jacking construction, how to choose the pipe and equipment for jacking, how to choose the engineering environment, how to do the geological survey before jacking, how to design the working pit, what's the procedure of pipe jacking, how to do the measurement and monitoring during jacking, how to do the treatment and acceptance after jacking, and so on. Appendix contains reference tables for pipe jacking archives, which might aid readers in understanding the book's content. This book's language is simple to read, and it has a wealth of graphics. Even those without a foundational understanding of pipe jacking could read and comprehend it with ease. This regulation could be the fundamental discipline for pipeline jacking projects. It is the important basis and criterion for the design, construction, management, inspection, and acceptance of pipeline jacking.

This book constitutes the refereed post-conference proceedings of the 2nd International Conference on Edge Computing and IoT, ICECI 2021, held in December 2021 in Shenzhen, China. Due to COVID-19 pandemic the conference was held virtually. The explosion of the big data generated by ubiquitous edge devices motivates the emergence of applying machine learning systems for edge computing and Internet of Things (IoT) services. Machine learning techniques are delivering a promising solution to the industry for building IoT systems and to make innovation at a rapid pace. The 12 full papers of ICECI 2021 were selected from 26 submissions and present results and ideas in the area of edge computing and IoT.

In view of grain security, a solution combines an adaptation of the cropping system with imports of surface water from the South. The Open Access book does not only describe the problem and the path to its solution.

This book introduces readers to adaptive interference mitigation techniques based on multiple antennas for global navigation satellite systems (GNSS) in the time, domain, spatial and spatial-temporal domains.

This book examines how educational change has progressed in three contrasting areas spread across China since 1990, exploring key issues concerning rural education in poor, rich and minority areas.
