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
Describes the passive intermodulation mechanism, analysis and
evaluation methods, location detection and suppression technology
of microwave components passive intermodulation from a theoretical
and engineering perspective Gives practical suppression technology
in the book, which provides reference for the engineers Introduces
the latest achievements of microwave components passive
intermodulation in a certain technical depth, guidance and
inspiration

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.
