The electrical capacitance and corresponding moisture content of cotton sample used as a sweat absorption container were investigated. Dependencies of interdigital sensor electrical capacitance from relative moisture content of fabric sample under investigation placed upon the sensor were plotted as the result of simulation in COMSOL Multiphysics software suite and experiments. The resulting dependence of the study allows the implementation of the human skin moisture content sensor for hyperhidrosis diagnostics.

Video surveillance applications have to support objects authentic in case of multiple objects tracking. During tracking process errors, caused by different circumstances, such as objects intersections among themselves, intersections with objects on the foreground, objects shape changes are possible. This article describes multiple objects tracking algorithm, based on system of object characteristics. The probabilistic model is based on the Kalman filter. The system is fully automated and does not require any manual input during initialization or execution.

The mathematical model and method of constructing optimal arrangements of the departments working hours based on the application of analysis systems are analysed. The model is based on the offer of all types of work representation in the department as a discrete set of resources, which has to de distributed between teachers according to the constraints and assumptions taken at the university.

A weighted iterative majority-logic decoding algorithm of cyclic codes with soft (quantized) detections of Phase-Modulating (PM) signals is analyzed. Evaluation of the correction capability of the algorithm on cyclic codes with quantization of PM signals of 8 levels, using a majority-logic algorithm with two decoding steps in a system of divided equations, was realized. It was shown that the obtained effectiveness evaluation of the soft decoding algorithm can be extended to cyclic codes based on majority-logic with systems of associates equations, and to compound cyclic codes.

An algorithm of adaptive lifting wavelet transform computation based on adaptive prediction of the detail wavelet coefficients, with using subbands halftone image obtained from the original grayscale is proposed. The results of an algorithm modeling show that it provides near lossless compression due to processing of insignificant coefficients defined by quantization error diffusion procedure.

Features of converted measurement Kalman filter implementations for polar coordinates and Doppler frequency measurements from radar survey are considered. The estimation performance of converted measurement Kalman filter modifications is compared.

The avalance effect has been investigated in an encryption algorithm being developed on the basis of the discrete chaotic maps. The avalanche effect has been analyzed in a discrete tent map and in the basic transformation based on the Feistel network with the use of the indicated map as a nonlinear function. In both cases, the analysis has been conducted in pairs “input value - output value” and “control parameter - output value”. It has been stated that under certain conditions the developed encryption algorithm meets the requirements of the avalance
