“A considerable amount of TIme has passed since steam engines, steamers,and railway engines have appeared. God saw that people’s life is difficultand boring. Then he decided to help them once more and gave themsignals as a present. The devil saw this and created noises, which he mixedup with the signals. People could not use noises and asked scienTIsts tospare them these troubles. People created methods and technologies offiltraTIon and suppression of noises. However, signals were distorted andmany valuable and concealed mysteries were lost together with the noise.”This book shows that characterisTIcs of signals and noises at the output ofsensors change continuously for both technical and biological objects atthe origin of a defect. The known classical conditions are not satisfied. Thetime for a decision about the problem increases.For these reasons, in some cases the detection of defects in informationsystems turns out to be overdue. Sometimes it results in catastrophic consequences.Taking into account these and other features of the initial stage of theorigin of the defect, several technologies are suggested. These technologiesallow one to perform the defect monitoring at the beginning of the defect’sorigin by extracting information from the noise. By duplicating and combiningthe above technological advantages, a necessary degree of reliabilityto the results is reached. These technologies are proved theoretically, andthe opportunity of their application for solving problems of noise monitoringat the beginning of the defect’s origin in oil-gas extraction, in construction,in power engineering, in transport, in seismology, in aviation, inmedicine, etc., is shown on numerous examples. In addition, they allow oneto improve the results of mathematical modeling, recognition, identification,control, etc., and they can find wide application in solving numerousproblems where processing and analysis of signals are required in variousfields of science and technology.The monograph is intended for teachers, post-graduate students, anduniversity students of all professions except the humanities, and also forexperts of power engineering, computer science, automation, physics, biology,geophysics, oil-gas extraction, transport, aviation, control, medicine, etc.
