Steganography is the art of communicating a secret message, hiding the very existence of a secret message. This is typically done by hiding the message within a non-sensitive document. Steganalysis is the art and science of detecting such hidden messages. The task in steganalysis is to take an object (communication) and classify it as either a steganogram or a clean document. Most recent solutions apply classification algorithms from machine learning and pattern recognition, which tackle problems too complex for analytical solution by teaching computers to learn from...

This series is devoted to the publication of proceedings of conferences or workshops sponsored by the Institut de Recherche Mathematique Avancee, Strasbourg, France, research monographs and other mathematical writings judged appropriate by the editor. The main focus will be proceedings of the international meetings between mathematicians and theoretical physicists (known under the French abbreviation "RCP") held at IRMA twice a year since about 30 years.

These meetings are aimed at creating and strengthening bridges between active mathematicians and physicists in the areas of...

Over the past few decades, the book series Linguistische Arbeiten Linguistic Studies], comprising over 500 volumes, has made a significant contribution to the development of linguistic theory both in Germany and internationally. The series will continue to deliver new impulses for research and maintain the central insight of linguistics that progress can only be made in acquiring new knowledge about human languages both synchronically and diachronically by closely combining empirical and theoretical analyses. To this end, we invite submission of high-quality linguistic studies...

During the course of this century, gauge invariance has slowly emerged from being an incidental symmetry of electromagnetism to being a fundamental geometrical principle underlying the four known fundamental physical interactions. The development has been in two stages. In the first stage (1916-1956) the geometrical significance of gauge-invariance gradually came to be appreciated and the original abelian gauge-invariance of electromagnetism was generalized to non-abelian gauge invariance. In the second stage (1960-1975) it was found that, contrary to first appearances, the non-abelian...

Quickly Engages in Applying Algorithmic Techniques to Solve Practical Signal Processing Problems

With its active, hands-on learning approach, this text enables readers to master the underlying principles of digital signal processing and its many applications in industries such as digital television, mobile and broadband communications, and medical/scientific devices. Carefully developed MATLAB(R) examples throughout the text illustrate the mathematical concepts and use of digital signal processing algorithms. Readers will develop a deeper understanding of how to apply the algorithms...

This is a self-contained book on the foundations and applications of optical and microwave technologies to telecommunication networks application, with an emphasis on access, local, road, cars, trains, vessels and airplanes, indoor and in-car data transmission as well as for long-distance fiber-systems and application in outer space and automation technology. The book provides a systematic discussion of physics/optics, electromagnetic wave theory, optical fibre technology, and the potential and limitations of optical and microwave transmission.
