Thanks to their considerable advantages, index modulation and orthogonal frequency division multiplexing (OFDM) are considered to be promising candidates for future wireless communications. This book focuses on the index modulation techniques for OFDM communications systems, which allow information to be conveyed not only via constellation symbols, but also by the indices of various transmission entities in OFDM systems, such as signal constellations, spreading codes, and pilots. The book discusses representative transmitter and receiver designs, optimization and performance analysis of index modulation based on various transmission entities. It first introduces readers to constellation-based index modulation via a combinatorial approach, including the classical index modulation scheme and two embodiments of information-guided precoding for OFDM systems. It further discusses constellation-based index modulation via a permutational approach, including the basic, generalized, and diversity-enhancing forms. It then describes how the spreading code is used to design an index modulated spread spectrum for OFDM systems, and the extensions to multi-code and multi-user scenarios. In addition it explores information guided pilot insertion for OFDM systems, followed by applications to carrier phase tracking and channel estimation. Lastly, the book highlights a number of open problems and discusses future research directions in the general field of index modulation. Intended for professionals and researchers in the field of wireless communications, this book is also a valuable resource for advanced-level electrical engineering and computer science students.

This book presents systematic overviews and bright insights into big data-driven intelligent fault diagnosis and prognosis for mechanical systems. The recent research results on deep transfer learning-based fault diagnosis, data-model fusion remaining useful life (RUL) prediction, etc., are focused on in the book. The contents are valuable and interesting to attract academic researchers, practitioners, and students in the field of prognostics and health management (PHM). Essential guidelines are provided for readers to understand, explore, and implement the presented methodologies, which promote further development of PHM in the big data era. Features: Addresses the critical challenges in the field of PHM at present Presents both fundamental and cutting-edge research theories on intelligent fault diagnosis and prognosis Provides abundant experimental validations and engineering cases of the presented methodologies

This book constitutes the refereed proceedings of the 6th International Symposium on Intelligence Computation and Applications, ISICA 2012, held in Wuhan, China, in October 2012. The 72 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on artificial life, adaptive behavior, agents, and ant colony optimization; combinatorial and numerical optimization; communications and computer networks; data mining; evolutionary multi-objective and dynamic optimization; intelligent computation, intelligent learning systems; neural networks; real-world applications.

Amid the turmoil of the Ming-Qing dynastic transition in seventeenth-century China, some intellectuals sought refuge in romantic memories from what they perceived as cataclysmic events. This volume presents two memoirs by famous men of letters, Reminiscences of the Plum Shadows Convent by Mao Xiang (1611-93) and Miscellaneous Records of Plank Bridge by Yu Huai (1616-96), that recall times spent with courtesans. They evoke the courtesan world in the final decades of the Ming dynasty and the aftermath of its collapse. Mao Xiang chronicles his relationship with the courtesan Dong Bai, who became his concubine two years before the Ming dynasty fell. His mournful remembrance of their life together, written shortly after her early death, includes harrowing descriptions of their wartime sufferings as well as idyllic depictions of romantic bliss. Yu Huai offers a group portrait of Nanjing courtesans, mixing personal memories with reported anecdotes. Writing fifty years after the fall of the Ming, he expresses a deep nostalgia for courtesan culture that bears the toll of individual loss and national calamity. Together, they shed light on the sensibilities of late Ming intellectuals: their recollections of refined pleasures and ruminations on the vagaries of memory coexist with political engagement and a belief in bearing witness. With an introduction and extensive annotations, Plum Shadows and Plank Bridge is a valuable source for the literature of remembrance, the representation of women, and the social role of intellectuals during a tumultuous period in Chinese history.
