This book focuses on the analysis and design of low-density parity-check (LDPC) coded modulations, which are becoming part of several current and future communication systems, such as high-throughput terrestrial and satellite wireless networks. In this book, a two-sided perspective on the design of LDPC coded systems is proposed, encompassing both code/modulation optimization (transmitter side) and detection algorithm design (receiver side). After introducing key concepts on error control coding, in particular LDPC coding, and detection techniques, the book presents several relevant applications. More precisely, by using advanced performance evaluation techniques, such as extrinsic information transfer charts, the optimization of coded modulation schemes are considered for (i) memoryless channels, (ii) dispersive and partial response channels, and (iii) concatenated systems including differential encoding. This book is designed to be used by graduate students working in the field of communication theory, with particular emphasis on LDPC coded communication schemes, and industry experts working on related fields.
Wireless channels are becoming more and more important, with the future development of wireless ad-hoc networks and the integration of mobile and satellite communications. To this end, algorithmic detection aspects (involved in the physical layer) will become fundamental in the design of a communication system. This book proposes a unified approach to detection for stochastic channels, with particular attention to wireless channels. The core idea is to show that the three main criteria of sequence detection, symbol detection and graph-based detection, can all be described within a general framework. This implies that a detection algorithm based on one criterion can be extended to the other c...
In this colorful depiction of daily political life in Baroque Rome, Laurie Nussdorfer argues that the lay persons managed to sustain a civic government under the increased papal absolutism of Urban VIII (1623-1644), who oversaw both sacred and secular life. Focusing on the S.P.Q.R. (the Senate and the Roman People), which was ministered from the capitoline Hill, she shows that it provided political representation for lay members of the urban elite, carried out the work of local government, and served as a symbol of the Roman voice in public life. Through a detailed study of how civic authorities derived their sense of legitimacy and how lay subjects maneuvered in informal and disguised ways ...
The Ruin of the Eternal City provides the first systematic analysis of the preservation practices of the popes, civic magistrates, and ordinary citizens of Renaissance Rome. This study offers a new understanding of historic preservation as it occurred during the extraordinary rebuilding of a great European capital city.
This proceedings volume provides a snapshot of the latest issues encountered in technical convergence and convergences of security technology. It explores how information science is core to most current research, industrial and commercial activities and consists of contributions covering topics including Ubiquitous Computing, Networks and Information Systems, Multimedia and Visualization, Middleware and Operating Systems, Security and Privacy, Data Mining and Artificial Intelligence, Software Engineering, and Web Technology. The proceedings introduce the most recent information technology and ideas, applications and problems related to technology convergence, illustrated through case studies, and reviews converging existing security techniques. Through this volume, readers will gain an understanding of the current state-of-the-art in information strategies and technologies of convergence security. The intended readership are researchers in academia, industry, and other research institutes focusing on information science and technology.
In the eighteenth and early nineteenth centuries the first modern, public museums of art—civic, state, or national—appeared throughout Europe, setting a standard for the nature of such institutions that has made its influence felt to the present day. Although the emergence of these museums was an international development, their shared history has not been systematically explored until now. Taking up that project, this volume includes chapters on fifteen of the earliest and still major examples, from the Capitoline Museum in Rome, opened in 1734, to the Alte Pinakothek in Munich, opened in 1836. These essays consider a number of issues, such as the nature, display, and growth of the muse...
An exciting new approach to understand the trade of antiquities in early modern Rome traces the journey of objects from discovery to display. Barbara Furlotti presents a dynamic interpretation of the early modern market for antiquities, relying on the innovative notion of archaeological finds as mobile items. She reconstructs the journey of ancient objects from digging sites to venues where they were sold, such as Roman marketplaces and antiquarians’ storage spaces; to sculptors’ workshops, where they were restored; and to Italian and other European collections, where they arrived after complicated and costly travel over land and sea. She shifts the attention away from collectors to peas...
Examines the nexus of learned culture and architecture in the 1730s to 1750s, including major building projects in Rome undertaken by the popes.
