PHYSICAL AND MATHEMATICAL SCIENCES

623-633 487
Abstract
A problem of structural-parametric control systems identification is considered. The method of genetic programming with the network operator is used. Network operator properties, rules of its creation and application are described. The basic solution approach is used for the genetic algorithm construction. It permits to apply genetic operations to the basic solution variations. The basic solution is set by a developer on the ground of his experience of concrete problem research. The selection of the basis solution influences on effectiveness of genetic algorithm. The results of computational experiment of the problem of identification solution are presented.

Abstract
A one-dimensional model and numerical solution of the non-stationary modes of the adiabatic gas-droplet chemical plug-flow reactor are considered. The developed approach permits to investigate processes of heat and mass transfer in the laminar flow of the reacting gas mixture with hydrocarbon fuels droplets. It may be useful for hazard operability.

Abstract
Modification results of the quasioptimal structural-parametrical synthesis algorithm for control devices based on using the frequency-based quality parameters vector of the system are considered. The addition of magnitude-frequency characteristic slope in a correction window to quality vector considerably raises efficiency of algorithm that gives the chance to investigate dependence between direct and indirect quality indicators for linear-converted control systems.

Abstract
The problem of mathematical model in complexation of production, work, services quality parameters is solved. Distribution of rank weights among and within quality parameters groups is considered. Distribution of quality parameters is described by the hyperbolic rank function. The method permits to plan work on quality parameters improvement with the aim of user satisfaction parameters growth.

PHILOLOGICAL SCIENCES

Abstract
A subordinate clause of time is considered as a way of rendering the meaning of action temporal localization/non-localization. temporal localization/non-localization meaning is conditioned by the semantics of the conjunctions of the subordinate clause of time. It is proved by the complex methodology of the text semantic interpretation.
