Now will reach considerable progress in experimental and theoretical researches of plasma systems with the turned magnetic configuration. Such systems possess unique physical properties and a number of technical advantages in comparison with other magnetic configurations for deduction of high-temperature plasma. In particular, pressure and the specific power maintenance of plasma are extremely high.

Work is devoted research of process of generation of powerful acoustic waves by the high-voltage pulse electric category in the liquid environment. Thanks to possibility of formation of impulses of pressure of high amplitude, this method allows to influence some characteristics of environment, such as structure, viscosity, dispersion. Possibility of improvement of characteristics of mineral oil, in particular, top internal black oil is considered.

A number of reactions of the synthesis going between kernels of easy elements with allocation of energy is known. These reactions, basically, can be used for creation of powerful energy sources.

Last 2-3 decades, characterised by continuous perfection of their design and increase of indicators, it is necessary to estimate development of piston internal combustion engines as accelerated that is caused by use of achievements of high technologies in the various branches connected with building of engines.

This paper presents review of the particle swarm optimization method (PSO) for a global optimization problem and its certain serial and parallel modifications.

In the article is considered the aufbau principle, the structure and the main deciding tasks of express-assessment system of technical state of explosive defense technologies after damaging influences. The offered tooling system of on-line diagnostics raises the efficiency of maintenance conditions of armament. This tooling system can be also the additional safety component by using of reactive, explosive and flammable products

In this paper, the unified concept of  ultra-, hyper- and usual directed and un directed graph is given. The connection between this types  of graph models is shown. The formal rules for  matrix and  analytical representations each type of graph are cited. 

The content of education carried out by means of computer-aided learning systems is defined by electronic educational resources – electronic text-books, electronic tutorials, reference books, applied programs of virtual laboratories and soon. These resources are developed by special instrumental systems. The information about technology and instrumental system of electronic educational resources creation adaptable for individual features and demands of trainees is represented.

             The paper discusses evaluation of conceptual knowledge of a subject taught by intellectual learning computer system whose knowledge database is built on semantic networks. Cognitive maps are used to formalize the conceptual knowledge of a subject about the studied discipline.

The analysis of the experimental results represented c by the purpose of definition of sizes on экспементально to registered dependences, concerns a known class a problem of Proni. It is possible to carry the assumption of Proni. To initial variants of statement of problems about экспоненциальном the law of decrease of pressure in a stream of extending gas, and also a problem of the analysis of structure of a breaking up mix of radioactive components.

The methods of numerical analysis of irregular nondissipative transmission lines with TEM-waves in frequency domain are considered. The examples of resolutions of irregular smooth and  uneven lines anallysis tasks in frequency domain are given. 

The methods of numerical synthesis of irregular nondissipative transmission lines with TEM-waves in frequency domain are considered. The resolution of irregular line synthesis task in frequency domain is given.  The algorithm of  cyclical  correction is described.

The algorithm of satellite radio navigating measurements providing decimeter accuracy of positioning in a mode of real time is described. The algorithm does not demand use of the additional information from other sources. The algorithm can be applied both to GPS, and to GPS + GLONASS to measurements. At use of special technics of the measurements named “the closed loop” , the algorithm allows to receive accuracy of positioning to units of centimetres.

Calculation of superbroadband devices, including devices of a filtration, radiation, etc. on smooth irregular lines of transfer (NLP) with T-waves is carried out with application of numerical methods as there are no analytical methods of calculation of their configuration. In this connection there is a constant search of the most effective methods of their synthesis. In given article the decision of the differential equation smooth NLP which considerably facilitates such synthesis is considered.

  Possibility of experimental determination a resilient member construction material physico-mathematical characteristics is based on analyzing it’s answer to a test harmonical stress by a linear oscillator . Resilient member material has a shape memory.

All people are consumers. Competition among manufacturers improves products quality, reduces its costs and forces buyers to choose among variety of goods the product, which would be the best choice for any private client. For example, any motorist at least once in his life was to choose a make of acquired car. The abundance of car techno-economic characteristics do not allow the buyer to make a clear choice. A decision support system for buying a car based on the mathematical apparatus of fuzzy logic is presented in this paper.

The paper discusses a parameterized three-dimensional model of internal combustion engine mechanical subsystem as an element of computer aided system of engines.  The model consists of some units which makes it possible to build a model of engine with various construction schemes. The problem is solved by using software PRADIS for analysis of dynamic systems.

The review of criteria of similarity ontologies, and also display methods ontologies is resulted

The paper deals with 3-D finite element analysis (FEA) of solid billet helical rolling process in terms of Eulerian description of continuun movement. The strained and stressed state of solid copper billet under 3-roll cold helical rolling process was investigated. The metal flow during the rolling process was estimated by using lengthwise and transversal rods specially implanted into the finite element model of the billet. As a result of computer simulation the time-dependent stress and strain fields and deformed shape of the billet and implanted rods were obtained. Power consumption of the process was estimated too. The analysis results were compared to the experimental ones and to the results of FEA in terms of Lagrangian finite element modelling problem definition.

Now prolongation of the appointed service life of technical devices is spent by an estimation of a technical condition лидерных or is artificial the made old samples. Such works pursue the aim — to define such service life at which physical and chemical processes of ageing yet do not worsen device technical characteristics. In the present article the original way of definition of a deadline of service of the nonrestorable technical device under the statistical data about refusals of this device in operation is offered.
