In this paper different approach to adaptation mechanism for fuzzy model reference learning control (FMRLC) method will be introduced. In comparison to original method the proposed procedure shows larger possibilities in design of FMRLC method. The main idea consists in new approach of design of the inverse model — an important part of FMRLC. This innovation is based on using more general fuzzy system in the inverse model, type-2 fuzzy system. Type-2 fuzzy systems are superior to classical fuzzy systems. From this reason using such systems in adaptation mechanism brings new possibilities. The advantages of the proposed modification are presented on control of magnetic suspension system and compared to FMRLC with convergent rule base.

A comparison of four algorithms form endpoint detection will be presented according to two different comparison techniques tests in different conditions. For the experiments two corpora were collected: one consisting of records with additive noise and other containing files recorded on an ordinary embedded microphone. The tests were conducted with assumption that hand-made boundaries may be considered as “gold standard”. Experiments have showed that the best results are achieved when only features based on short-time energy are used. Also it has revealed that pre-emphasis of the source signal may have negative effect on the result of the analysis.

In the paper, the base device for a frequency division circuit (FDC) system is calculated. Evaluation of the characteristics with maximum approximation to theoretically ideal is carried out. A diplexer for the ground penetration radar is investigated using L and C lumped elements. The diplexer shows very small insertion loss, and the VSWR of less than 2.0 through the all pass-band. The theoretical analysis of the FDC is carried out basing of the differential equation method. The standard strategy of filter synthesis is applied for synthesis of the FDC structure.

An analytical method for solving nonlinear differential equation that describes the Bouc-Wen model of dynamic hysteresis is proposed. Solution is sought in the form of successive approximations based on the Fourier transforms. The results confirm the efficiency of this method.

Medium waveband navigation systems are considered. Systems using code-division multiplexing have intrasystem interference level determined by cross-correlation sidelobe. Interference immunity of spread spectrum signal with minimum shift keying correlation receiver is improved with powerful adjacent-channel interference compensator providing high accuracy interference copy forming. Correlation receiver equipped with compensator modeling denotes that designed compensator provides high signal dynamic range around 80 dB and higher in terms of Doppler frequency shift equals from 0 to 0.2 Hz and 14-bit analog-to-digital converting with limited dynamic range.

The crystal structure of the bismuth cobaltite Bi24(CoBi)O40 is determined. The resistivity and thermoelectromotive force measurement in the temperature range of 80–1000 K is performed. The temperature hysteresis of resistivity below the temperature Т = 950 K is revealed. The crossover from semiconductor to metallic behavior of thermoelectromotive force versus temperature is found at high temperatures.
