It has been postulated that humans can differentiate between millions of gradations in color. Not surprisingly, no completely adequate, detailed catalog of colors has yet been devised, however the quest to understand, record, and depict color is as old as the quest to understand the fundamentals of the physical world and the nature of human consciousness. Rolf Kuehni’s Color Space and Its Divisions: Color Order from Antiquity to the Present represents an ambitious and unprecedented history
* A historical account of color order systems
* Fundamentals of psychophysics and the relationship between stimuli and experience
* Results of perceptual scaling of colors according to attributes
* History of the development of mathematical color space and difference formulas
* Analysis of the agreements and discrepancies in psychophysical data describing color differences
* An experimental plan for the reliable, replicated perceptual data necessary to make progress in the field. |

The book focuses on a recently emerging topic in security. Specifically, the book focuses on physical layer security. Whereas conventional security mechanisms involve cryptography that operates at higher layers of the protocol stack, the methods described in this book secure communications at the physical layer.
The area of physical layer security is an emerging field of research that has seen an explosion of research in the past few years. This trend is only expected to continue as there is a growing need to secure wireless communications without conventional cryptographic network security protocols.
The proposed book will consist of contributions from roughly a dozen of the leading research groups in this emerging area. For the first time, important results will be collected together. Important topics will include the secrecy rate of MIMO wireless systems, practical codes for the dissemination of secrets, and authentication of wireless transmitters using waveform-level properties. |
