This textbook systematically introduces the theories, methods, and algorithms for geotechnical reliability analysis. There are a lot of illustrative examples in the textbook such that readers can easily grasp the concepts and theories related to geotechnical reliability analysis. A unique feature of the textbook is that computer codes are also provided through carefully designed examples such that the methods and the algorithms described in the textbook can be easily understood. In addition, the computer codes are flexible and can be conveniently extended to analyze different types of realistic problems with little additional efforts.

Rockfall impacts have seriously threatened the operations of buried pipelines in geologically unstable regions. In this book, mechanical behaviour of oil and gas pipeline impacted by a rockfall was investigated by numerical simulation. In chapter 1, collapse reasons of rockfalls and impact force of buried pipeline impacted by a rockfall were introduced. In chapter 2, mechanical behavior of a ground pipeline impacted by a rockfall (normal impact, longitudinal inclined impact, transverse inclined impact and eccentric impact) was investigated. In chapter 3 and 4, buckling behavior of a buried pipeline in soil stratum and rock stratum impacted by a rockfall were studied. Effects of pipeline parameters, rockfall parameters and surrounding soil parameters on the pipeline¿s mechanical behavior were researched. In chapter 5, mechanical behavior of a buried pipeline under surface load caused by rockfalls were investigated. In chapter 6¿a protective device of buried pipelines is designed for preventing rockfalls impact. Those results can be used for laying construction, safety evaluation and protection engineering of oil and gas pipelines in bad geological regions.

Earth-affecting solar transients encompass a broad range of phenomena, including major solar flares, CMEs, ICMEs, solar energetic particle events, and corotating interaction regions.¿In the past decade, nearly continuous observations of the Sun and the inner heliosphere with an unprecedented wide spatial coverage from a fleet of spacecraft, including STEREO Ahead/Behind, SDO, SOHO, Messenger, Venus Express, ACE and WIND, in combination with a significant advancement of global MHD numerical simulation and theoretical analysis, have greatly improved our understanding of solar transients and the prediction of their potential impact on Earth.This Topical Collection is based on the International Study of Earth-affecting Solar Transients (ISEST) project, initially launched in 2013 to bring together scientists from many countries to join efforts on studying solar transients. ISEST became one of the four research projects of the Variability of the Sun and Its Terrestrial Impact (VarSITI) program, sponsored by the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) for the period of 2014¿-¿2018.Originally published in the journal Solar Physics, volumes 292 (2017) and 293 (2018).

This thesis presents an accurate and advanced numerical methodology to remedy difficulties such as direct numerical simulation of magnetohydrodynamic (MHD) flow in computational fluid dynamics (CFD), grid generation processes in tokamak fusion facilities, and the coupling between the surface tension force and Lorentz force in the metallurgical industry. In addition, on the basis of the numerical platform it establishes, it also investigates selected interesting topics, e.g. single bubble motion under the influence of either vertical or horizontal magnetic fields. Furthermore, it confirms the relation between the bubble's path instability and wake instability, and observes the anisotropic (isotropic) effect of the vertical (horizontal) magnetic field on the vortex structures, which determines the dynamic behavior of the rising bubble. The direct numerical simulation of magnetohydrodynamic (MHD) flows has proven difficult in the field of computational fluid dynamic (CFD) research, because it not only concerns the coupling of the equations governing the electromagnetic field and the fluid motion, but also calls for suitable numerical methods for computing the electromagnetic field. In tokamak fusion facilities, where the MHD effect is significant and the flow domain is complex, the process of grid generation requires considerable time and effort. Moreover, in the metallurgical industry, where multiphase MHD flows are usually encountered, the coupling between the surface tension force and Lorentz force adds to the difficulty of deriving direct numerical simulations.

This book systematically introduces modeling, performance evaluation and applications of Automatic Materiel Handling System (AMHS) in semiconductor manufactucing, and focuses discussion on the coordination of two subsystems. Resources dispatch and optimization are conducted on operational research combined with cases studies. Written in a practical way, it is an essential reference for researchers and engineers in manufacturing and management.
