Coding is an highly integral component of viable and efficient computer and data communications, yet the often heavy mathematics that form the basis of coding can prevent a serious and practical understanding of this important area.

"Coding for Data and Computer Communications" eschews the complex mathematics and clearly describes the core concepts, principles, and methods of channel codes ( for error correction), source codes (for compressing data), and secure codes (for cryptography, data hiding, and privacy). Conveniently organized and segmented into three associated parts for...

Security protocols are widely used to ensure secure communications over insecure networks, such as the internet or airwaves. These protocols use strong cryptography to prevent intruders from reading or modifying the messages. However, using cryptography is not enough to ensure their correctness. Combined with their typical small size, which suggests that one could easily assess their correctness, this often results in incorrectly designed protocols.

The authors present a methodology for formally describing security protocols and their environment. This methodology includes a model...

Nowadays it is hard to find an electronic device which does not use codes: for example, we listen to music via heavily encoded audio CD's and we watch movies via encoded DVD's. There is at least one area where the use of encoding/decoding is not so developed, yet: Flash non-volatile memories. Flash memory high-density, low power, cost effectiveness, and scalable design make it an ideal choice to fuel the explosion of multimedia products, like USB keys, MP3 players, digital cameras and solid-state disk.

In ECC for Non-Volatile Memories the authors expose the basics of coding...

A big amount of important, economically relevant information, is buried within the huge mass of multimedia documents that correspond to some form of narrative description.

Due to the ubiquity of these narrative resources, being able to represent in a general, accurate, and effective way their semantic content i.e., their key meaning is then both conceptually relevant and economically important. In this book, we present the main properties of NKRL ( Narrative Knowledge Representation Language ), a language expressly designed for representing, in a standardised way, the meaning of complex...

Autonomic Computing and Networking presents introductory and advanced topics on autonomic computing and networking with emphasis on architectures, protocols, services, privacy & security, simulation and implementation testbeds. Autonomic computing and networking are new computing and networking paradigms that allow the creation of self-managing and self-controlling computing and networking environments using techniques such as distributed algorithms and context-awareness to dynamically control networking functions without human interventions. Autonomic networking is characterized by...

Over the last decade a number of research areas have contributed to the concept of advanced intelligent environments, these include ubiquitous computing, pervasive computing, embedded intelligence, intelligent user interfaces, human factors, intelligent buildings, mobile communications, domestic robots, intelligent sensors, artistic and architectural design and ambient intelligence. Undeniably, multimodal spoken language dialogue interaction is a key factor in ensuring natural interaction and therefore of particular interest for advanced intelligent environments. It will therefore...
