This book is based on the monograph Acoustic Echo and Noise Control, which was published by Wiley (2004). The information has been revised and updated with important new information included. The book contains fundamental analysis of new topics such as bandwidth extension and speech enhancement by partial signal reconstruction. Emphasis is put on entire systems such as speech dialog systems and in-car communication systems. The latter record the speech of the driver and the passenger in a car, process these signals to get rid of background and feedback components, and finally play them back via loudspeakers located close to the backseat passengers.

Translated by Robin Alexander No one has written about the Sun like this! It is neither scientific in the usual sense, nor religious from an establishment view. Georg Blattmann integrates these disciplines in a form that may annoy, stimulate, anger, or cause wonder in the reader. Beginning with simple observations of the Sun and our own feelings for its life-giving power, the author examines its corona, temperature, and surface to arrive at startling conclusions about the inside of the Sun. He shows it as something "completely different." Using projective geometry, he provides a basis for a mathematical and physical understanding of the Sun. This enables us without too much difficulty to enter the spiritual realities connected with the Sun. And, using examples from the history of art, from astrophysics, and from the Gospels of the Bible, Blattmann shows the hidden connection between the Sun and the Christ.

Does children's nutrition influence their mental development? This question is asked frequently today. In most instances the answer, coming as the real result of extensive study, is that nutrition and mental development are definitely interrelated. It happens that the question is often asked only in regard to brain development, yet research clearly shows concrete links between the two poles of spiritual–mental activity and the physical human brain. For a clear understanding of these connections, an approach is needed that, on the one hand, is able to develop a true picture of the human being, and, on the other, is able to see through to the interdependent activities of the human organization and its environment. The method that allows us to forge ahead to real understanding was established by Rudolf Steiner as modern research through Spiritual Science (or Anthroposophy).

The authors set out the theory and methods for quality enhancement of clean and distorted speech signals such as those that have undergone a band limitation in a telephone network. Problems and solutions are discussed for the different approaches.

The strategy and tactics associated with the open file are explained here clearly and comprehensivelyhow files are opened, blocked, occupied, and exploited as roads along which to invade the enemy position. A brief introduction lays the theoretical foundations and is followed by illustrative games, in all of which the open file is the dominant or deciding factor. In each game there is a pause at a key position where a clear verbal assessment is given; these assessments teach the reader how strong chess players thinkwhat to look for, how to assess, and how to plan. The book benefits not only from Gerhard Schmidt’s experience as a trainer but also from the huge knowledge and skill gained by Grandmaster Wolfgang Uhlmann during his long and successful career in top-class chess.
