The authors consider the problem of identifying objects with stochastic discrete - continuous nature of the process. Moreover, the emphasis is not only on the presence of random noise in different channels of communication, but also on the lack of information about the course of the process. Special attention is paid to the case when the design is applied to control the impact of a real object in a distorted, for several reasons. Additionally, the problem of identification of multidimensional stochastic systems is investigated in a closed loop, in the form of a macroscopic object, including a system “object-regulator”. The authors consider the question of the impact of the current information about the input to manage the impact on the quality of identification in noisy environments, with different sampling step. The results of numerical studies of nonparametric multidimensional models of processes with memory are presented.

This paper addresses the problem of presenting deep semantics of words, sentences, narrations and texts of the natural language within such a form of data presentation as semantic web. A model of multilevel semantic web of words is offered where word graph nodes and arcs include a graph of the inner level semantic web of semes. A method of semantic web different levels correlations on the words and semes level is offered based on the matrixes, including the equivalent arguments of the natural language words semantics elements. The issue of ordering the multilevel semantic web on the vector-based semantic data classification is touched upon. A conclusion is made about the necessity of the continuation of the research concerning the necessity to elaborate the software of deep semantics description matrixes generation.

The variation and differential method of calculation of plates tension in the conditions of a flat task of the elasticity theory in functions of tension is developed. The method of elimination of deformations of S. Tymoshenko is applied to the solution of a temperature task. The functionality in functions of tension, taking into account the temperature member that exempts from calculation of deformations, is received. The feature of the developed algorithm of calculation is the usage of the allowing equations and its right part of the first and second variations of this functionality for formation of coefficients of the system. It gives a universal algorithm of calculations when the same procedure in program modules is applied. The finite-differential discretization sampling of a continual task allows to solve problems of a big dimension. Tension on a contour is known a priori; in the field of a plate the equation of continuity is provided at rather rare finite-differential grids, the counting duration and resources of memory is small. The calculation program on the basis of a Maple package is made; the example of calculation of a free plate is given at uneven heating.

Reshetnev 31, Krasnoyarsky Rabochy Av., Krasnoyarsk, 660014, Russian Federation E-mail: blackdeathangel@rambler.ru The article describes software multiversioned views and its application to ensure that the system is processing realtime data. This methodology is based on the introduction of software redundancy and allows to significantly increase the reliability of the software. As a practical example of application software of this type management system, the data processing system of real-time long-term orbital station was chosen. Based on the available data about the long-term orbital station to the task of representing the flight plan from a sequence of modes of operation of the station, with specified restrictions was developed. The experiments were conducted using standard ant colony algorithm developed on the test task.

The article discusses a hammer operation technique, the drive of which is a linear electrodynamic motor. The relationship between the current pulse in the rotor field winding with impact energy is studied. In static mode of the electrodynamic hammer the currents are fed to coil winding and the rotor field winding, the current magnitude is sufficient to draw the rotor into the stator and keeping it in the upper position. Then current pulse is fed to the rotor field winding to provide the rotor stroke. The direction of the current pulse is the opposite to the current direction in the static mode. Current pulse duration is shorter than it takes to reverse magnetization of the stator magnetic core, but it exceeds the duration of the rotor stroke. The results of tests of electrodynamic hammers are presented.

Aluminum alloys used in aerospacemachine-building are divided into two classes - casting, which the components of complicated geometry (eg. frame cases of aviation free-piston engines and turbo-pump assemblies of liquid-propellant rocket engines) are made from, and deformable,which the ingots are casted of, afterwards the plates are made by rolling for fuel tanks made by welding and also frames, stringers, longerons, power frames made by pressing. By preparation the alloys of both groups, in essence, the identical technologies reduced to two main - degassing (moving hydrogen off) and modification (decomposition of structure) are used. However, the products of interaction between fining and modifying substances and fluid metal often remain in liquid. And it makes the quality of molded articles worse. The results of investigations for the refinement of metallic liquids from these products by filtration during ingots casting by semicontinuos method and so during details casting are demonstrated in this work.
