Focusing on the non-Western context and case studies, this book explores theories of interdisciplinary architectural thinking and the construction of urban memory in Chinese cities, with an emphasis on contemporary architecture and the diversity of agencies.China has undergone one of the fastest urbanisation and urban renewal processes in human history, but discussions of urban memory in China have tended to be practice-oriented and lack theoretical reflection. This book brings together interdisciplinary architectural scholarship to interrogate the production of urban memory and examine experiences in China. The 14 chapters explore different processes, projects, materials, architecture and urban spaces in different Chinese cities by analysing cityscapes such as temples, bridges, conservation projects, architectural design, historical architecture, memorial hall, market street, city images, custom bike, food market and so on. The book deals with different agencies and methods, tangible and intangible, in the construction of memories aimed at promoting hybridised multiple identities, and explores the interplay of different versions of memory, i.e. state, public, regional, local, individual and collective memory.This book will be essential reading for scholars and students of architecture and urbanism, cultural studies and China studies, as well as architects, urban planners and historians interested in these fields.

The late 1970s to the mid-1980s, a period commonly referred to as the post-Mao cultural thaw, was a key transitional phase in the evolution of Chinese science fiction. This period served as a bridge between science-popularization science fiction of the 1950s and 1960s and New Wave Chinese science fiction from the 1990s into the twenty-first century. Chinese Science Fiction during the Post-Mao Cultural Thaw surveys the field of Chinese science fiction and its multimedia practice, analysing and assessing science fiction works by well-known writers such as Ye Yonglie, Zheng Wenguang, Tong Enzheng, and Xiao Jianheng, as well as the often-overlooked tech–science fiction writers of the post-Mao thaw.Exploring the socio-political and cultural dynamics of science-related Chinese literature during this period, Hua Li combines close readings of original Chinese literary texts with literary analysis informed by scholarship on science fiction as a genre, Chinese literary history, and media studies. Li argues that this science fiction of the post-Mao thaw began its rise as a type of government-backed literature, yet it often stirred up controversy and received pushback as a contentious and boundary-breaking genre. Topically structured and interdisciplinary in scope, Chinese Science Fiction during the Post-Mao Cultural Thaw will appeal to both scholars and fans of science fiction.

This volume brings together emerging approaches and addresses shifting paradigms in Chinese science fiction studies, offering a window on fan cultures, internet fiction, gender, eco-criticism, post-humanism and biomedical discourse.

This volume illustrates Asian speculative fiction's potential to interrogate and inspire humanity's ecological and ethical responsibilities, seeking to fill a major lacuna in previous academic literature around ecocriticism in speculative fiction. Contributions are thematically organized into three sections—Human-Nature Co-evolution and Ecomedia, Technologies and East Asian Heritage, and Posthuman Ecology. Chapter authors draw on global viewpoints to provide a multi-dimensional analysis that includes Indigenous knowledge, trans-local (inter-Asian) exchanges, and perspectives from the Global South. To end, the book provides a reflection on how speculative fiction promotes a vision of interconnected kinship among humans, the nonhuman, and the natural world.

This book focuses on novel reduced cell and stack models for proton exchange membrane fuel cells (PEMFCs) and planar solid oxide fuel cells (P-SOFCs) that serve to reduce the computational cost by two orders of magnitude or more with desired numerical accuracy, while capturing both the average properties and the variability of the dependent variables in the 3D counterparts. The information provided can also be applied to other kinds of plate-type fuel cells whose flow fields consist of parallel plain channels separated by solid ribs. These fast and efficient models allow statistical sensitivity analysis for a sample size in the order of 1000 without prohibitive computational cost to be performed to investigate not only the individual, but also the simultaneous effects of a group of varying geometrical, material, and operational parameters. This provides important information for cell/stack design, and to illustrate this, Monte Carlo simulation of the reduced P-SOFCmodel is conducted at both the single-cell and stack levels.

The science of mathematical modelling and numerical simulation is generally accepted as the third mode of scienti?c discovery (with the other two modes being experiment and analysis), making this ?eld an integral component of c- ting edge scienti?c and industrial research in most domains. This is especially so in advanced biomaterials such as polymeric hydrogels responsive to biostimuli for a wide range of potential BioMEMS applications, where multiphysics and mul- phase are common requirements. These environmental stimuli-responsive hydrogels are often known as smart hydrogels. In the published studies on the smart or stimu- responsive hydrogels, the literature search clearly indicates that the vast majority are experimental based. In particular, although there are a few published books on the smart hydrogels, none is involved in the modelling of smart hydrogels. For the few published journal papers that conducted mathematical modelling and numerical simulation, results were far from satisfactory, and showed signi?cant d- crepancies when compared with existing experimental data. This has resulted in ad hoc studies of these hydrogel materials mainly conducted by trial and error. This is a very time-consuming and inef?cient process, and certain aspects of fun- mental knowledge are often missed or overlooked, resulting in off-tangent research directions.
