Introduction. Recently, a new class of information technologies (IT) — intelligent IT is widespread which, unlike traditional, operate generalized concepts — images, and provide more complete information about the external environment. One of the tasks requiring the involvement of intelligent IT — analysis and interpretation of complex form signals with a locally-focused information.

The purpose of the article is — to formulate the basic properties of intelligent IT complex form signal processing, demonstrate the ability to implement these features on the example of the innovative method fasegraphy and outline prospects for further development of this technology.

Methods. Fasegraphy is a high IT which is processing different complex form signals of physical nature, which, basing on a chain of intelligent computational procedures, enables the transition from the observed signal with a locally-focused features (raw material for technology) to information which is focused on a particular user (technology product). The main task of the scientific method fasegraphy aims to detect general laws of indicated signals to identify and use in practice the most effective computational procedures that can ensure this transition.

Results. Basic properties of intelligent IT — adaptation, learning, generalization, invariance, forecasting, understanding, flexibility, interoperability, accessibility have been formulated. Analysis of computational procedures chain in fasegraphy method, that provide a transition from the actually observed signals to technology product, shows that the method has all of the above properties, and therefore fasegraphy can be referred to intelligent ITs. New results have been presented from fasegraphy usage in pediatric cardiology and outlined prospects for the development of this method in two ways — by increasing the reliability of decision making in single-channel ECG and realization of intelligent processing tasks of other signals with locally-focused features.

Conclusions. Fasegraphy intelligent capabilities are far from exhausted and can be used to solve actual scientific and applied problems not only in cardiology but also in other applications.

Introduction. The problem of increasing network performance is very relevant. In practice, the actual speed of data transmission / receiving is significantly lower than the bit rate supported by used network technology. The actual wireless network bandwidth depends on the used technology, the number of subscribers in the network, length and quality of communication channels, electromagnetic interference, weather, network equipment, protocols and many other factors.

The purpose. The project is based on applied research in the field of high-speed cycles control systems for net-centric dynamic application processes with spatially-distributed interrelated functional components. Thus it provides functional and temporal combination of internal resources of net-centric distributed control systems with objects and technological processes on the basis of shared use of dynamics models working in an accelerated time scale into a single space-time net-centric complex.

Results. To solve the problem of determining the quality of the data transfer process in order to further control and manage this process, a method which is based on software that works with any standardized computing environment was developed. This method detects and evaluates the operating parameters of the wired Internet network before, during and after transmission of the information data packets provides analytical (numerical values of time delay of packet transmission, the percentage of lost data, signal quality, transmission speed and receive speed) and graphic parameters to control information transmission routes. This paper provides the results of computer simulation which are represent the network connection quality.

Conclusion. Development a method for determining the quality of information data transmission via a wireless connection, also as a creating programs for protection against unauthorized network access — are a perspective research objectives. Results of simulations confirm the appropriateness of using the given method of data transfer control in the terrestrial wired data transmission systems and the need to develop such technology for wireless connection.

PROBLEM OF MODEL ORDER REDUCTION FOR LINEAR LARGE-SCALE TIME-INVARIANT SYSTEM

Gubarev V.F.

Space Research Institute NAS Ukraine and SSA Ukraine, Kiev, Ukraine

v.f.gubarev@gmail.com

Introduction. Very significant for application model reduction problem of large-scale time-invariant system to more simple small order is considered and developed in the paper. Real and approximate models fitting is determined by norms which establish the difference between impulse response of these two models.

The purpose of the article is to propose a new approach of setting the model reduction problem and to develop methods based on variational principle of its solving.

Methods. It is proposed to set model reduction problem as optimization. For this initial state space model was transformed to equivalent description in form of input-output relation using analytical expression for impulse response. Such form allows to apply conception of fit between real system and its low-order approximation widely used in identification. Parameters of approximate model and its dimention are determined from optimization problem with different measure of fit writing as norm. Algorithms of numerical solving the optimization problems and needed for this data are considered in the paper. Besides the modified subspace method that permits to construct the observability matrix directly from output data using SVD factorization is proposed and described. Singular values of SVD-decomposition indicate as the best way to truncate full model.

Results. Some results dealing with mutual disposition of eigenvalues of real model and reduced one are demonstrated.

Conclusion. Developed methods may be used both for systems with scalar input and output and for multi-input and multi-output system as well. Results obtained by modelling show efficiency of all worked out methods.

Keywords: model reduction, approximation, optimization, model fit, state-space model.

g.chikrii@gmail.com

Introduction. Mathematical theory of control under conflict and uncertainty provides a wide range of fundamental methods to study controlled evolutionary processes of various nature. These are, first of all, the classic methods of L.S. Pontryagin and N.N. Krasovskii. This paper is closely related to the mentioned investigations. It is devoted to research of non-stationary game dynamic problems on the basis of the L.S. Pontryagin first direct method and the method of resolving functions.

The purpose of the paper is to derive sufficient conditions for the game termination for some guaranteed time in favor of the first player and to provide the control realizing this result.

Results. Here, in the development of the method of resolving functions general scheme, the upper and the lower resolving functions of two types are introduced in the form of selections of special set-valued mappings. This made it possible to deduce conditions for the game termination in the class of quasi- and stroboscopic strategies.

Conclusions. The in-depth analysis of properties of the set-valued mappings and their selections, around which measurable controls are chosen by virtue of the Filippov-Castaing theorem, is provided. A comparison of the guaranteed times of the above-mentioned methods is given.

Keywords: Conflict controlled processes, set — valued map, Pontryagin’s condition, Aumann’s integral, resolving function.

SYSTEM OF CRYPTOGRAPHIC TRANSFORMATIONS OF NUMBERS BY MEANS OF LINEAR RECURRENT FORMS

Anisimov A.V.

Taras Shevchenko National University of Kiev, Ukraine

ava@unicyb.kiev.ua

Introduction. Two-level system of encoding integers by linear forms aPn + bQn, where Pn and Qn are linear recurrent sequences. These sequences are defined by factoring quadratic irrationalities into continued fractions. Firstly, a number x is represented as a form x = aAn + bBn, where An / Bn is a convergent to some fixed quadratic irrationality. At the second stage the triple (a, b, n) is encoded by a maximal linear form of another linear recurrent sequence (a, b, n) -> cPn + dPn+1. The sequences An, Bn, Pn are considered as hidden symmetric keys given by coefficients of corresponding quadratic irrationalities. Properties of such encodings are established.

The purpose of the article is to develop and study a nondeterministic system of cryptographic integer encoding by means of linear recurrent sequences.

Methods. We used methods of continued fractions, properties of linear forms, and bijective encoding of natural numbers.

Results. We proved as a theorem that such a system of encoding is absolutely resistant to passive crypto-attacks. With some further additions it is also resistant to stronger types of attacks.

Conclusion. The proposed system of integer encoding is easy to construct, and it has some proven properties that allows using it as a primitive basic procedure for light weighted cryptography.

Keywords: Linear forms, continued fractions, nondeterministic cryptography.
