This book presents a complete and accurate study of algebraic circuits, digital circuits whose performance can be associated with any algebraic structure. The authors distinguish between basic algebraic circuits, such as Linear Feedback Shift Registers (LFSRs) and cellular automata and algebraic circuits, such as finite fields or Galois fields.

The book includes a comprehensive review of representation systems, of arithmetic circuits implementing basic and more complex operations and of the residue number systems (RNS). It presents a study of basic algebraic circuits such as LFSRs...

The study of signal transmission and deterioration in signal characteristics as the signal propagates through wireless channels is of great significance. The book presents a comprehensive view of channel degradation arising from fading and shadowing. Various statistical models including simple, hybrid, compound, complex and cascaded ones are presented with detailed derivations along with measures to quantify the deterioration such as the amount of fading, error rates and outage probabilities. The models range from the Rayleigh and Rician through Suzuki, generalized K, cascaded and alpha-mu...

Biometrics in the New World takes a fresh look at biometrics and identity management within a fast-changing world.

The concept of biometric identity verification is revisited, including identity intelligence, federation and the use of third party infrastructure. Furthermore, the book examines some of the fundamentals of the technology which are often overlooked. However, the dialogue extends beyond technical considerations, and explores some of the broader societal and philosophical aspects surrounding the use of biometric applications, bringing this whole area into a new...

Policy informatics is addressing governance challenges and their consequences, which span the seeming inability of governments to solve complex problems and the disaffection of people from their governments. Policy informatics seeks approaches that enable our governance systems to address increasingly complex challenges and to meet the rising expectations of people to be full participants in their communities. This book approaches these challenges by applying a combination of the latest American and European approaches in applying complex systems modeling, crowdsourcing, participatory...

The video coding standard High Efficiency Video Coding (HEVC) targets at improved compression performance for video resolutions of HD and beyond, providing Ultra HD video at similar compressed bit rates as for HD video encoded with the well-established video coding standard H.264/AVC. Based on known concepts, new coding structures and improved coding tools have been developed and specified in HEVC. The standard is expected to be taken up easily by established industry as well as new endeavors, answering the needs of todays connected and ever-evolving online world.
