Development and investigation of the methods for adaptive forecasting and statistical identification based on non-linear dynamic models of physical and economic processes

The method of GARCH model synthesis (Generalized autoregressive conditional heteroscedasticity) was developed for prediction of maximal sample conditional variances of output coordinates of multidimensional heteroscedastic processes with multirate discretization. To achieve maximal prediction accuracy the algorithm of adaptive adjustment of GARCH model coefficients was devised.

Development of integrated Receiver & Transmitter module in millimeter-wave band for wide band wireless access system

The new constructions of millimeter wave band pass and band stop filters were designed. Filters are builded on the cheap plastic metalized substrates and are suitable for integration into the all-planar millimeter wave transceivers. The new constructions of hybrid integrated low-noise millimeter wave oscillators for frequency up- and down converters were designed. Oscillators can be used in the wireless broadband access system. The new constructions of all-planar orthomode transducers were designed and investigated both theoretically and experimentally.

Simulation and realization of solid-state electrically tuning filters

The solid-state electrically tuning filters are main elements of different multifrequency communication systems with high reliability. New approach to designing electrically tuned band-pass filters that is based on use U-shaped microstrip resonators with several varactors connected to each resonator is proposed. This approach allows to creating prototypes which exceeds world level of varactor-tuned filters.

System researches and applications of the diagnostics facilities for the analysis of the explosions influence on the iron-ore careers of the Crooked Horn on building

The analysis of the modern state of program and technical operative diagnostics facilities of the building objects stress-deformed state under difficult engineer-geological and seismic conditions is conducted. The theoretic-methodology ground of experimental methods of complex geophysical researches of the litodynamic earthly surface processes for industrial explosions on an iron-ore quarry the "South ore mining enterprise" is executed.
