Theory of Spinors and Its Application in Physics and Mechanics
by Vladimir A. ZhelnorovichThis book contains a systematic exposition of the theory of spinors in finite-dimensional Euclidean and Riemannian spaces. The applications of spinors in field theory and relativistic mechanics of continuous media are considered. The main mathematical part is connected with the study of invariant algebraic and geometric relations between spinors and tensors. The theory of spinors and the methods of the tensor representation of spinors and spinor equations are thoroughly expounded in four-dimensional and three-dimensional spaces. Very useful and important relations are derived that express the derivatives of the spinor fields in terms of the derivatives of various tensor fields.The problems associated with an invariant description of spinors as objects that do not depend on the choice of a coordinate system are addressed in detail. As an application, the author considers an invariant tensor formulation of certain classes of differential spinor equations containing, in particular, the most important spinor equations of field theory and quantum mechanics. Exact solutions of the Einstein–Dirac equations, nonlinear Heisenberg’s spinor equations, and equations for relativistic spin fluids are given. The book presents a large body of factual material and is suited for use as a handbook. It is intended for specialists in theoretical physics, as well as for students and post-graduate students of physical and mathematical specialties.

Sustainable Development in Mountain Regions
by Georgi ZhelezovThe mountain regions in Southeastern Europe are unique natural regions of great beauty and ecological value, and home of the head waters of major rivers. They constitute a major ecological, economic, cultural, recreational and living environment in Europe, shared by numerous cultures and countries. The Southeastern European Mountain Regions are an important reservoir for biodiversity and habitats in Europe. A great number of protected areas - national parks, nature parks, reserves and nature monuments are located in these regions. From a socio-economic point of view the mountain regions are among the poorest areas in the Southeastern European countries, but they have potential for the implementation of successful economic activities. There are opportunities for development of these regions and, in particular, for trans-border integration and co-operation. This book brings together research results from experts from all Balkan countries working on the problems of the mountain regions in Southeastern Europe. The volume focuses on the challenges taking place along the rapid transformation in land use, biodiversity, tourism, nature risk and bio-productivity due to the global changes and particularly due to the local impacts of climate change. The key questions for discussion are: - Biodiversity, nature protection and conservation - Natural disasters and risk management - Social-economical development of the mountain regions - Spatial planning in the development of the mountain regions - Sustainable practices and politics for land use - Transborder co-operation.
Institutional Logics and Practice of the Evolution of Urban–Rural Relationships (Social Development Experiences in China)
by Xiaoye Zhe Yun AiThis book mainly analyzes the major issues at all phases of the transition of urban-rural relation, as well as measures adopted by the transition launcher in face of such issues, including not only the system and policy design of the national and local government, but the countermeasures of basic-level units at urban and rural areas and the people. Through reference of the social structure and social behavior, it proposes “opportunity structures”, “interactive mechanism” and “behavior strategies” for different periods, which to some degree promotes the transition of urban-rural relation and brings in new, more complicated issues for the development. It is under the impact of such new and existing issues that big problem follows when the urban-rural relation steps onto a new stage, showing several paths and practices different from the general urbanization and modernization theories.
Advanced Methods of Joint Inversion and Fusion of Multiphysics Data (Advances in Geological Science)
by Michael S. ZhdanovDifferent physical or geophysical methods provide information about distinctive physical properties of the objects, e.g., rock formations and mineralization. In many cases, this information is mutually complementary, which makes it natural for consideration in a joint inversion of the multiphysics data. Inversion of the observed data for a particular experiment is subject to considerable uncertainty and ambiguity. One productive approach to reducing uncertainty is to invert several types of data jointly. Nonuniqueness can also be reduced by incorporating additional information derived from available a priori knowledge about the target to reduce the search space for the solution. This additional information can be incorporated in the form of a joint inversion of multiphysics data.Generally established joint inversion methods, however, are inadequate for incorporating typical physical or geological complexity. For example, analytic, empirical, or statistical correlations between different physical properties may exist for only part of the model, and their specific form may be unknown. Features or structures that are present in the data of one physical method may not be present in the data generated by another physical method or may not be equally resolvable.This book presents and illustrates several advanced, new approaches to joint inversion and data fusion, which do not require a priori knowledge of specific empirical or statistical relationships between the different model parameters or their attributes. These approaches include the following novel methods, among others: 1) the Gramian method, which enforces the correlation between different parameters; 2) joint total variation functional or joint focusing stabilizers, e.g., minimum support and minimum gradient support constraints; 3) data fusion employing a joint minimum entropy stabilizer, which yields the simplest multiphysics solution that fits the multi-modal data. In addition, the book describes the principles of using artificial intelligence (AI) in solving multiphysics inverse problems. The book also presents in detail both the mathematical principles of these advanced approaches to joint inversion of multiphysics data and successful case histories of regional-scale and deposit-scale geophysical studies to illustrate their indicated advantages.

Controlling Differential Settlement of Highway Soft Soil Subgrade: A New Method And Its Engineering Applications (SpringerBriefs in Applied Sciences and Technology)
by Yongli Zhao Mengchong Chen Zhijun Wu Hanhua ZhuDrawing on years of practical on-site experience, this book presents a new method for controlling "bridge-head bumping" in soft soil ground. Based on deformation compatibility and control theory of structure, it proposes strategies for improving the design method of soft soil ground and the effective "bridge-head bumping" control method. Soft soil ground is chiefly characterized by a large void ratio, high compressibility, high water content, low impermeability, low strength, strong structure and high sensitivity. As a result, it has pronounced rheological properties, and controlling "bridge-head bumping" in soft soil ground is essential to control the amount of soil rheology-induced unstable successive settlement. The book offers extensive information on this and related topics, making it a valuable guide for engineers in Civil Engineering and Geotechnical Engineering alike.
China's Disappearing Countryside: Towards Sustainable Land Governance for the Poor
by Yongjun ZhaoWhile China’s hybrid rural land tenure system has contributed to agricultural development, it is interwoven with rising farmland loss and social conflicts.This book examines the linkages between land tenure, development and governance in the context of China’s development transformation. Drawing on empirical studies, it advocates the exploration of innovative land tenure systems that address the wider determinants: institutions, power, politics and social development. It argues that a land tenure system can only be sustainable when it is compatible with the overall biophysical, social, political and economic conditions. This new institutional lens into the conditions and dynamics of land tenure systems marks a paradigm shift away from those focusing on the narrow meaning of land rights and tenure security strengthening, as these approaches can paradoxically contribute to weaker land and resource governance. Contributing to an enhanced understanding of the challenges China faces in agricultural development and natural resource governance and to the international debates on land tenure reform, this book will be of interest to researchers, practitioners, policy-makers and students in development studies, anthropology, sociology, political sciences, law, geography, economics, public administration and other relevant disciplines. The lessons learnt from China also shed light on its global engagement on sustainable development and governance issues.

Developing an Appropriate Contaminated Land Regime in China
by Xiaobo ZhaoLike all industrialized countries, China has encountered increasing problems with land contamination in recent years. Abandoned mining and manufacturing sites and obsolete industrial complexes, while also creating new polluting industrial enterprises, represent impending environmental threats. More importantly, a number of social and economic problems have developed and must be dealt with, in some cases urgently. Contaminated land laws and regulations have been established and have evolved in the US and UK and many other jurisdictions over the past few decades. These regimes have substantially influenced the relevant legislation in the context of numerous Asian and European countries and will inevitably benefit similar legislative efforts in China. This book is the first monograph that focuses on how China can learn from the US and UK with respect to contaminated land legislation and comprehensively illustrates how contaminated land law could be created in China. It will be of interest to academics and practitioners in environmental law in China, as well as the US and UK.
Coupled DEM-CFD Analyses of Landslide-Induced Debris Flows (Springer Tracts in Civil Engineering)
by Tao ZhaoThis book reflects the latest research results in computer modelling of landslide-induced debris flows. The book establishes an understanding of the initiation and propagation mechanisms of landslides by means of numerical simulations, so that mitigation strategies to reduce the long-term losses from landslide hazards can be devised. In this context, the book employs the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD) to investigate the mechanical and hydraulic behaviour of granular materials involved in landslides - an approach that yields meaningful insights into the flow mechanisms, concerning e. g. the mobilization of sediments, the generation and dissipation of excess pore water pressures, and the evolution of effective stresses. As such, the book provides valuable information, useful methods and robust numerical tools that can be successfully applied in the field of debris flow research.
