A Thematic Dictionary of Contemporary Chinese is a unique resource for intermediate to advanced students of Chinese. The dictionary presents 9,000 words organized thematically in approximately 300 different subject areas. These themes cover the vocabulary necessary for daily use and for conducting meaningful conversations with native Chinese speakers on a variety of topics, from politics to business, and from hobbies to education. Each vocabulary item is annotated with the most frequent collocations, allowing learners to improve their fluency by storing new vocabulary in larger linguistic units. Cultural and linguistic tips enable learners to grasp the vocabulary more effectively and increase their awareness of Chinese culture embedded in the language. Review exercises are provided throughout to ensure learners have ample opportunity to practice the new material. This is a great resource for both independent study and classroom use and will be of interest to students and teachers of Chinese alike. For further understanding of Chinese expressions, students are encouraged to read 500 Common Chinese Proverbs and Colloquial Expressions and 500 Common Chinese Idioms.

China and Africa have long shared a history of allegiance and contact points through global political forces from the time of colonialism and the Cold War. With China's rise as the new superpower, its presence in Africa has expanded, leading to significant economic, geopolitical and cultural shifts. While issues such as trade, aid and development have received much attention, Chinese and African encounters through the lens of the visual arts and material culture is a neglected field.Visualising China in Southern Africa: Biography, Circulation, Transgression is a ground-breaking volume that addresses this deficit through engaging with the work of contemporary African and Chinese artists while analysing broader material production that prefigures the current relationship. The essays are wide-ranging in their analysis of ceramics, photography, painting, etching, sculpture, film, performance, postcards, stamps, installations, political posters, cartoons and architecture.Visualising China in Southern Africa confines its focus to southern Africa, yet even within this region, the context is complex. Ethnicity and nationalism, the lingering influence of Cold War allegiances and colonial configurations all continue to play a role. The various visual cultures discussed in this volume emphasise the commonality of these categories, but also point towards other shared histories that transcend the nation-state category.The collection includes scholarly chapters, photo essays, interviews, and artists' personal accounts, organised around four themes: material flows, orientations and transgressions, spatial imaginaries, and biographies. The artists, photographers, filmmakers, curators and collectors in this volume include: Stary Mwaba, Hua Jiming, Anawana Haloba, Gerald Machona, Nobukho Nqaba, Marcus Neustetter, Brett Murray, Diane Victor, William Kentridge, Kristin NG-Yang, Kok Nam, Mark Lewis, the Chinese Camera Club of South Africa, Wu Jing, Henion Han and Shengkai Wu.

This book thoroughly analyzes the crucial role of supersonic separator technology in addressing the challenges of environmental degradation and climate change, particularly highlighting its importance in the dehydration and decarbonization of natural gas.

This book constitutes the refereed proceedings of the 8th International Conference on Rough Sets and Current Trends in Computing, RSCTC, held in Chengdu, China, in August 2012, as one of the co-located conferences of the 2012 Joint Rough Set Symposium, JRS 2012. The 55 revised full papers presented together with one keynote paper were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on rough sets and its applications; current trends in computing; decision-theoretic rough set model and applications; formal concept analysis and granular computing; mining complex data with granular computing; data mining competition.

The LNCS journal Transactions on Rough Sets is devoted to the entire spectrum of rough sets related issues, from logical and mathematical foundations, through all aspects of rough set theory and its applications, such as data mining, knowledge discovery, and intelligent information processing, to relations between rough sets and other approaches to uncertainty, vagueness, and incompleteness, such as fuzzy sets and theory of evidence.Volume XVIII includes extensions of papers from the Joint Rough Set Symposium (JRS 2012), which was held in Chengdu, China, in August 2012. The seven papers that constitute this volume deal with topics such as: rough fuzzy sets, intuitionistic fuzzy sets, multi-granulation rough sets, decision-theoretic rough sets, three-way decisions and their applications in attribute reduction, feature selection, overlapping clustering, data mining, cost-sensitive learning, face recognition, and spam filtering.

This book revisits the long-standing puzzle of cross-scale energy transfer and dissipation in plasma turbulence and introduces new perspectives based on both magnetohydrodynamic (MHD) and Vlasov models. The classical energy cascade scenario is key in explaining the heating of corona and solar wind. By employing a high-resolution hybrid (compact finite difference & WENO) scheme, the book studies the features of compressible MHD cascade in detail, for example, in order to approximate a real plasma cascade as “Kolmogorov-like” and to understand features that go beyond the usual simplified theories based on incompressible models. When approaching kinetic scales where plasma effects must be considered, it uses an elementary analysis of the Vlasov–Maxwell equations to help identify the channels through which energy transfer must be dissipated. In addition, it shows that the pressure–strain interaction is of great significance in producing internal energy. This analysis, in contrast to many other recent studies, does not make assumptions about wave-modes, instability or other specific mechanisms responsible for the dynamics – the results are direct consequences of the Vlasov–Maxwell system of equations. This is an important step toward understanding dissipation in turbulent collisionless plasma in space and astrophysics.
