This book is based on more than a decade of research the authors have pursued on the pseudo-seismic migration imaging of the transient electromagnetic method, and provides a series of important findings on the theory and applications in this area. It present and analyzes transforming principles, TEM wave field methods, characteristics of the TEM virtual wave field and studies on many significant related technologies. The coverage is supplemented by a wealth of 1-D, 2-D and 3-D figures to illustrate pseudo-seismic theory. The book offers a valuable resource for teachers, students, researchers and engineers in the fields of geophysics, earth exploration and information technology.
This book focuses on essential theories, methods and techniques in the field of environmental and engineering geophysics that can contribute to resource detection and environmental protection. Geophysics has been playing an important role in exploring the earth, locating vital resources and promoting the development of society. This book covers a range of topics including the exploration of modern resources, such as ore deposits, coal mines, shale gas and geothermal power, and the monitoring of geological disasters, including the rock-soil body, ground deformation, mines, specific rock-soil engineering disasters, desertification of land and environmental abnormalities. This book not only offers a valuable resource for geophysical researchers; it also demonstrates how geophysics theories and methods can be practically implemented to protect our environment and promote the development of human society.
The polar regions are very cold and very windy. There is snow and ice everywhere, but I love my home. My feet help me walk on the slippery ice, but I am not a penguin. My thick fur keeps me warm but I am not an Arctic fox. What animal am I? Read the clues and guess!

Project planning is generally accepted as an important contributor to project success. However, is there research that affirms the positive impact of project planning and gives guidance on how much effort should be spent on planning? To answer these questions, this book looks at current literature and new research of this under-studied area of project management. The author presents his findings from an extensive review of project planning literature that covers more than 270 sources. He also discusses new research that analyzes data from more than 1,300 global projects. The book confirms that the time spent on planning activities reduces risk and significantly increases the chances of proje...
