Telman Aliev developed the theory and technology of noise analysis of random signals.

He also proposed algorithms and technologies for analyzing the noise as a carrier of useful information, showing the possibility of their use in control systems and also for correction of errors of traditional methods of signal analysis.

Aliev established that at the beginning of the latent period of catastrophic accidents of technical facilities, only the estimates of the noise of the signal change, while the readings of the measuring instruments of control systems remain unchanged, and only the noise becomes the carrier of diagnostic information.

As a result, intelligent systems have been developed for Noise control of the beginning, dynamics of development and prediction of accidents on offshore platforms, at oil and gas production facilities at drilling rigs, at power engineering facilities, at pumping stations, in heating systems, on the rolling stock of trains, as well as on the railroad track, bridges and tunnels, etc.

The system alarms about the start of a change in the seismic situation, determining the zone of the focus of the expected earthquake.
