First, the authors lay down the preliminary neuroscience background for engineers. The book also presents an overview of the role of correlation in the human brain as well as in the adaptive signal processing world; unifies many well-established synaptic adaptations (learning) rules within the correlation-based learning framework, focusing on a particular correlative learning paradigm, ALOPEX; and presents case studies that illustrate how to use different computational tools and ALOPEX to help readers understand certain brain functions or fit specific engineering applications.
This book focuses on undergraduate student engagement in China and the UK. It offers an innovative perspective on this aspect, which, although pervasive, is not always acknowledged by its users to be complex and multidimensional in nature, firmly rooted in cultural, social and disciplinary norms, and difficult to measure. Competition within the global higher education market has become increasingly intense amongst universities; and the higher education sector in China, currently the largest source of international students, is beginning to compete strongly for its home market. Against this consumerist background, student engagement, with its close relation to positive learning outcomes, is increasingly receiving attention from higher education managers and researchers who seek to improve the quality of their ‘products’. The research study on which the book is based draws on three courses, two in China and one in the UK. It offers a binary perspective across two very different cultures (Western and Confucian) and two very different subject areas (Chinese language and mathematics). The study employs a mixed-methods design and develops a conceptual framework derived from statistical and thematic analysis. An original theoretical lens, combining a bioecological perspective (Bronfenbrenner) and a sociocultural one (Holland et al.’s Figured Worlds), adds further interpretive power to help understand the construct of student engagement.
Lossless Information Hiding in Images introduces many state-of-the-art lossless hiding schemes, most of which come from the authors' publications in the past five years. After reading this book, readers will be able to immediately grasp the status, the typical algorithms, and the trend of the field of lossless information hiding. Lossless information hiding is a technique that enables images to be authenticated and then restored to their original forms by removing the watermark and replacing overridden images.

In her previous life, Lin Sitian had made a lot of money, but she died of cancer at such a young age, alone and desolately, in the hospital. After her rebirth, when facing her eccentric parents, she thought that her ten fingers still had some length. Moreover, when it came to matters between right and wrong, they were still very clear and could be trained. However, those relatives who were instigated by them and harbored evil intentions would not hold back. They would only slap them in the face. In this life, Lin Siqiang's goals were to become a bookworm and lead her family to become rich, then walk towards the peak of life. However, why was that proud and pampered man everywhere he went? It occupied her entire heart.

Beijing-based writer Lin Zhe's novel Waipode Gucheng, on which this translation is faithfully based, paints an unforgettable picture of an "ordinary" family caught up in the maelstrom that was China's most recent century. Her narrative ranges across the entire length of China, to California and back again, to the battlefields of the Anti-Japanese War of Resistance and the brutal "struggle" sessions of the Cultural Revolution. But it always returns to this family's home in Old Town, that archetypical, old-fashioned, and vanishing place steeped in the traditions of South China. Ms. Lin examines the inner strength that sustains people's lives in their darkest hours, when religious and political faith falter. And yet, a vein of irony and droll humor runs through this powerful story. Lin Zhe's novel may be understood as a love story, memoir, history, or allegory. For the non-Chinese reader it provides a rare and moving insight into Chinese lives in a century of fearsome upheaval.
There are two parts to the book. In the first part, a complete introduction of various kinds of a priori estimate methods for the Dirichlet problem of second order elliptic partial differential equations is presented. In the second part, the existence and regularity theories of the Dirichlet problem for linear and nonlinear second order elliptic partial differential systems are introduced. The book features appropriate materials and is an excellent textbook for graduate students. The volume is also useful as a reference source for undergraduate mathematics majors, graduate students, professors, and scientists.
The boundary element method (BEM) divides only the boundaries of the region under investigation into elements, so it diminishes the dimensionality of the problem, e.g., the 3D problem becomes a 2D problem, and the 2D problem becomes a 1D problem. This simplifies inputting the model into a computer and greatly reduces the number of algebraic equations. The advantage of this is even more evident for some 3D and infinite regional problems that often are encountered in geophysics. Originally published in China, this well-organized book is likely the most comprehensive work on the subject of solving applied geophysical problems. Basic mathematical principles are introduced in Chapter 1, followed by a general yet thorough discussion of BEM in Chapter 2. Chapters 3 through 7 introduce the applications of BEM to solve problems of potential-field continuation and transformation, gravity and magnetic anomalies modeling, electric resistivity and induced polarization field modeling, magnetotelluric modeling, and various seismic modeling problems. Finally, in Chapter 8, a brief discussion is provided on how to incorporate BEM and the finite-element method (FEM) together. In each chapter, detailed practical examples are given, and comparisons to both analytic and other numerical solutions are presented. This is an excellent book for numerically oriented geophysicists and for use as a textbook in numerical-analysis classes.
This 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.
Centering on issues of disparity and equality in basic public education services in China, this book proposes a performance measurement system that assesses and guides equality of basic public education in urban and rural areas. The author moves beyond traditional research approaches by drawing on methods of public management and mathematics. Pivoted on an improved balanced scorecard model, a complete set of indicators and measuring tools are constructed, whereby the process of education equality can be more effectively measured, managed, and steered. Grounded in empirical studies on public education in the country's Sichuan Province, the book advances suggestions on better policies and optimizing implementation for the purpose of attaining equitable public education services in urban and rural areas. Finally, the study envisages further research directions and possible applications of the performance appraisal model. The title will be of value to scholars and students of education studies, especially those interested in public education, educational equity, and Chinese public education services.
