This book integrates the analyses of organic carbon and carbonate accumulation in soil and lake sediment in a typical arid region of China that has experienced significant climate and land-use changes. It demonstrates that carbonate accumulation greatly exceeds organic carbon in both soil and sediment. It also shows that intensive cropping with sound land management in the arid land not only increases soil organic carbon stock, but also enhances accumulation of soil carbonate, particularly in subsoils. Carbon accumulation in the lake sediment increased between 1950 and 2000, after which it declined, and the authors explore how human activity and climate change may have caused the changes in carbon burial in the lake sediment. This book is of interest to researchers in a number of fields such as soil science, limnology and global change, as well as to the policy-makers.

This book focuses on the performance optimization of fault diagnosis methods for power systems including both model-driven ones, such as the linear parameter varying algorithm, and data-driven ones, such as random matrix theory. Studies on fault diagnosis of power systems have long been the focus of electrical engineers and scientists. Pursuing a holistic approach to improve the accuracy and efficiency of existing methods, the underlying concepts toward several algorithms are introduced and then further applied in various situations for fault diagnosis of power systems in this book. The primary audience for the book would be the scholars and graduate students whose research topics including the control theory, applied mathematics, fault detection, and so on.

The processing of signals or data is one of the cores of the information chain from production to application. More and more signals should be processed digitally in the big data era. Rapid and massive advances in digital signal processing (DSP) technology have been achieved over the past several decades. DSP technology revolutionized the electronics and opto-electronics industries. DSP technology is almost an all-embracing field and is advancing with each passing day. The classical application areas of DSP such as telecommunications, speech and image processing continue to be the main contributor to its growth. This book compiles cutting-edge research in several elementary and advanced topics in DSP, focusing on areas such as filter design algorithms, hardware/software techniques, and their applications. This book has a special emphasis on the modeling and design of optical communication filters. Use of well-developed DSP techniques and algorithms to design the wavelength division multiplexing (WDM) devices is a wise use of existing technology. The authors also share several of their thoughts concerning the practical DSP systems. The DSP theory and hardware for obscured object identification, and its applications in the intelligent baggage scanners are introduced systematically. This book will be helpful for students, researchers and engineers in the DSP fields to understand the basic knowledge and techniques of software, hardware, devices, and systems.
