This article presents the features of functioning the cyber-physical systems and their components. The cyber-physical systems are complex systems which components may be located at great distance from one another. The cyber-physical systems perform processing of information and functions of monitoring and control equipment. Cyber-physical systems infrastructure mainly consists of subsystems, which electronic components are implemented through the embedded system control and get information about the environment through sensors and measuring device and can influence it through actuators.

Existent approaches to determination of basic concepts of information theory, coming from the statistical reasoning (classic approach), theory of algorithms (algorithmic approach) and theory of pattern recognition (vivid approach) are examined. Their comparative analysis is conducted. Approach which enables in number to estimate the value of information is offered.

The scientific and practical problem of automatic detection of meaningful keywords and Ukrainian content categorization in Internet systems on the basis of linguistic analysis of text information is unleashed. The article presents a theoretical and experimental substantiation of linguistic analysis methods for Ukrainian content using Porter stemming.

This article is about determination of process of adaptation, data structure of algorithms editor. Mathematical model of data structure of algorithms editor, hierarchical-modular construction principle of editor, of adaptation process and expanding and collapsing processes were synthesized, minimized and built.

Designed by the algorithm of the control system vertical, multi-level, electromagnetic separator with pulsed magnetic fields of high intensity. Proposed selection criterion the optimal algorithm functioning of the separator control system.

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.

The research findings in the sphere of mathematical modeling of modern broadband wireless access have been revealed in the article. Detailed description of algorithm program realized in multi- antenna channel has been provided. The distinctive feature of this algorithm is taking into account the digital signal processing correlation properties of multi-antenna channel.

In the article the method of collection, analysis and working of information is described on the example of the high school. The charts of functioning of algorithm and methods of working of information are developed in the set subject domain.
