When using the prediction in the control of the rotational motion is necessary to construct two smooth trajectories passing through the previously measured its nodal points. As a piecewise polynomial curve that provides the desired smoothness, consider interpolating cubic splines, which are between nodes represent a cubic parabola, continuously connecting the nodes with the smoothness of degree 2. In imposing additional boundary conditions, these splines minimize its total curvature.

The article describes the best ways spline interpolation trajectories of angular movement in the key points for solving motion control rd to the prediction of the external load. As benchmarks we examine the accuracy of the approximation of the drive and the complexity of calculation of coefficients of splines.

In this article considered the questions related to how the deformability is influenced in concrete beams, in which steel reinforcement replaced with fiberglass GFRP or a combination (hybrid). The latter is very important, as the current standards do not account the increased in strength of composite reinforcement, whereas its elasticity modulus is lower than the elasticity modulus of steel reinforcement.

Currently most used energy absorbers can be represented classic spring-damper scheme in which the binding is the presence of the elastic work item and damper. Applied to seysmoudarnomu works best security systems installations are systems that do not have elastic elements. For hard metals, which are material for the work items absorber characterized by the appearance of a tooth during the deformation strength. For the calculation of the power characteristics of the work item should be modeled phenomenon associated with the formation of the yield drop. Modeling of the phenomenon of this article.

The model of increase of efficiency of the created system of transportation of a municipal waste is presented. Need for carrying out modeling and the actions connected with reorganization of system, because of possible increase in total expenses is proved at shift of positions of reloading stations of rather optimum points owing to local conditions of the territory of municipality.

The algorithm of construction of reflections from the screens of complex shape. Geometric modeling based on the proposed algorithm makes it possible to conduct a rapid assessment of the distances between the fire building complex geometry, and between the process equipment, which is characterized by heat. Analytical dependences describing the process of building reflections, software algorithms and examples of calculations.

This article is related to technological problems of cavities with kamufletnyh explosions, during which the temperature in the cavity greatly exceeds the initial temperature of the array. Often these cavities are created in an array of rock salt. Because the salt even at light loads demonstrate expressive flow properties, it is interesting solution to the problem of creep salt massif with a cavity under the action of a force (pressure inside the cavity and the pressure of the soil), and thermal loads.

The article describes such categories of psychotherapeutic discourse as its participants, aims, values, specific concepts. Special attention is given to the means of the categories’ expression in the language. The authors name so called teleonomic concepts of the psychotherapeutic discourse (life – death), discourse –specific concept relationship is also in focus. It is noted that psychotherapeutic discourse is of a metaphorical nature.
Keywords: psychotherapeutic discourse, discourse participants, relationship, discourse metaphorical nature
The algorithm, which allows to apply the Prony method to estimate of the sources parameters using vector-scalar receiving array is discussed. Noise immunity of the proposed algorithm is very high, so as the measured components of the acoustic field does not contain a noise.
