The results of the pulse-width modulation algorithms analysis are presented in the paper. The following two algorithms are analyzed: pulse-width modulator (PWM) based on the sawtooth waveform generator and PWM based on an integrator and a switch element. Mathematical formulae for designing the tuning parameters of PWM algorithms are presented. An improved PWM algorithm is suggested for a programmable logic controller (PLC) operating with integer variables without a filter of the input signal.

In this paper the problem of estimating the importance of each of the characteristics of steganographic algorithms is solved. The resulting estimates are used in the analysis of the existing algorithms for information embedding and multiobjective choice of the best algorithm. The technique allows providing an equally weighted algorithms estimation, and also considers the importance of coefficients of characteristics.

This article is about determination of properties of unitherms. The algorithm of calculating geometrical parameters of unitherms is introduced. The mathematical model is synthesized. This model is then minimized and built. The algorithm of calculating geometrical parameters of unitherms is probed into.

The grounding task of identification the flagrant error limits of measurings is decided in height geodesic networks at their search by the analysis of misclosures in grounds. Certainly critical intervals of rough errors identification in a ground depending on the amount of the stations and measurement errors in it.

For the specified ski courses relief research the algorithm and then the program ‘Course Calculation’ were developed. On the basis of the two-dimensional terrain image it is possible to design the arbitrary amount of ski courses profiles variants. The basic parameters

of the ski course relief are determined and also compared to the normative values
