The long-term time-series prediction of the debris flow activity in Carpathian mountains' hydrogeologic region territory

Analysis of the debris flow formation factors which cause the long-term activity of debris flows is made. The methodology of the debris flows prediction subject to meteorological, hydrological, seismic, heliophysical factors is proposed. The regularities of long-term seasonality of these factors by using autocorrelation and spectral analysis are revealed. The integral rate of probability of debris flow intensification is calculated. The time series of this integral rate is extrapolated and the following peak of debris flows activation is predicted.

Spectral and Correlation Analysis of Signals With Continuous and Discrete Frequency Modulation

Complex signals are used typically for solving electromagnetic compatibility of radio electronic devices, stable and efficient in their work under intense action of active and passive noise. Using complex signals with linear frequency modulation (LFM), in particular, provides higher resolution than the range and the speed, and can significantly improve information radio.
