This book is composed of eight chapters, introducing the authors’
research and application achievements in the hazard-causing system
and disaster evaluation of water and mud inrush in tunnels over the
past 10 years. Through a large number of case studies and analysis,
and on the basis of existing research, this book puts forward 3
categories and 11 types of tunnel water and mud inrush
hazard-causing systems and 4 typical water and mud inrush
disaster-forming modes. The authors carefully study the typical
cases of tunnel water and mud inrush hazard-causing system, discuss
the types of karst water system, structural characteristics,
macro-geological identification, engineering identification, karst
tunnel route selection principles and evaluation methods in detail,
and then develop a dynamic evaluation method of tunnel water and
mud inrush construction risk interval and an evaluation method for
the resistance body. Ultimately, the authors put forward a
systematic identification method of tunnel water and mud inrush
disaster, which integrates geological identification, geophysical
exploration identification, and drilling identification, and
construct a dynamic management and analysis platform for tunnel
water and mud inrush cases. This book is used as a reference book
for teachers, graduate students, and undergraduates in colleges and
universities of civil engineering, transportation, water
conservancy and hydropower, mining, geology, etc., and also as a
reference for technicians in related engineering fields.

This book is focused on fundamental aspects of climate variability
in the ocean, in particular changes of the wind-driven circulation.
The vertical movement of isopycnal (isothermal) layers, including
their stretching and compression, is called heaving and stretching.
A major part of climate variability in the ocean is heaving in
nature. Heave is primarily associated with the adiabatic motions of
isopycnal layers due to change of wind stress. It is rather
difficult to separate the contributions from adiabatic and diabatic
processes. Isopycnal analysis has been widely used in climate
study; however, it is much more accurate to study the isopycnal
layers. Here climate signals are examined in terms of changes of
layer depth, layer thickness, layer temperature/salinity, spicity
and others. In addition to the traditional Theta-S diagram, the
sigma-pi (potential density - potential spicity) diagram can also
be used in analyzing water mass property distribution and climate
variability. In fact, a radius of signal can be defined rigorously
for signals in the sigma-pi diagram; the combination of isopycnal
analysis and evaluation of radius of signal provides a powerful
tool in analyzing climate variability in the world oceans.

The volume of data being collected in solar astronomy has
exponentially increased over the past decade and we will be
entering the age of petabyte solar data. Deep learning has been an
invaluable tool exploited to efficiently extract key information
from the massive solar observation data, to solve the tasks of data
archiving/classification, object detection and recognition.
Astronomical study starts with imaging from recorded raw data,
followed by image processing, such as image reconstruction,
inpainting and generation, to enhance imaging quality. We study
deep learning for solar image processing. First, image
deconvolution is investigated for synthesis aperture imaging.
Second, image inpainting is explored to repair over-saturated solar
image due to light intensity beyond threshold of optical lens.
Third, image translation among UV/EUV observation of the
chromosphere/corona, Ha observation of the chromosphere and
magnetogram of the photosphere is realized by using GAN, exhibiting
powerful image domain transfer ability among multiple wavebands and
different observation devices. It can compensate the lack of
observation time or waveband. In addition, time series model, e.g.,
LSTM, is exploited to forecast solar burst and solar activity
indices. This book presents a comprehensive overview of the deep
learning applications in solar astronomy. It is suitable for the
students and young researchers who are major in astronomy and
computer science, especially interdisciplinary research of them.

Communities serve as basic structural building blocks for
understanding the organization of many real-world networks,
including social, biological, collaboration, and communication
networks. Recently, community search over graphs has attracted
significantly increasing attention, from small, simple, and static
graphs to big, evolving, attributed, and location-based graphs. In
this book, we first review the basic concepts of networks,
communities, and various kinds of dense subgraph models. We then
survey the state of the art in community search techniques on
various kinds of networks across different application areas.
Specifically, we discuss cohesive community search, attributed
community search, social circle discovery, and geo-social group
search. We highlight the challenges posed by different community
search problems. We present their motivations, principles,
methodologies, algorithms, and applications, and provide a
comprehensive comparison of the existing techniques. This book
finally concludes by listing publicly available real-world datasets
and useful tools for facilitating further research, and by offering
further readings and future directions of research in this
important and growing area.
The interaction between ocean circulation and climate change has
been an active research frontier in Earth sciences in recent years.
Ocean circulation, and its related geophysical fluid dynamical
principles, are now taught at graduate level in many Earth and
atmospheric science departments. This is the first advanced
textbook to discuss both wind-driven and thermohaline-driven
processes - two important aspects of large-scale ocean circulation.
It provides a concise introduction to the dynamics and
thermodynamics of oceanic general circulation. This includes sea
water thermodynamics and the energetics of the ocean circulation;
an exhaustive theory of wind-driven circulation; thermohaline
circulation with discussions on water mass formation/erosion, deep
circulation, and the hydrological cycle; and interactions between
wind-driven and thermohaline circulation. Highly illustrated to
help the reader establish a clear mental picture of the physical
principles involved, the book is invaluable for advanced courses in
ocean circulation and as a reference for oceanographers and Earth
scientists.
Very few books published so far have touched upon commodity finance
and fewer still have provided a systematic explanation and analysis
of the subject. It is however a subject that is relevant throughout
almost every corner of the world From food to gold, commodities are
ubiquitious. In this book, Dr. W. Huang, a practitioner and a
trainer, covers commodities, commodity markets, commodity trade and
the finance of commodity trade. As such, practitioners such as
bankers and traders in commodity finance, and those institutions
operating in this field, or planning to be active in this field,
will all benefit from this book. This revised and updated second
edition is a hands-on summary of commodity finance, with a special
chapter dedicated to real-life case studies of commodity finance.
Topics covered include: - High-level overview of commodity trade
and finance. - The three major sectors of commodity finance: soft
commodities, hard commodities and energy - Commodity finance and
emerging markets, as most commodity export countries are emerging
markets countries. - The special mechanisms and products of
commodity finance, from plain vanilla products to more complicated
structures. The concept of Supply Chain Finance is also covered in
detail. - Bank and country risk. - Risk management principles, with
practical case studies. - The organization of a typical commodity
finance bank. The key benefits of the book are: For bankers - how
to do business and what risks should be watched for? For traders,
brokers and institutional investors - how commodity finance is done
and what bank instruments can be used. For students - how is
commodity finance handled and developed by banks? Each chapter can
be read independently. The content has been reviewed by both
experts and newcomers, incorporating their comments on style and
content, to ensure it is as useful and clear as possible.
