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.

Results of the flight research spent in April - among students of RSUCE are brought May, 2012. The Main objective of research - definition of the emotional relation of students to local and central political orders. Primary data are received by questioning on a method of semantic differential. By the received results semantic portraits of four types of political usages (two ideal constructions and two above-stated real orders), relative distances in semantic space between images of these usages are defined. That has allowed to calculate levels of emotional perception of local and central political usages in linear approach.

In this article considered the questions related to the strength of normal sections in reinforced concrete beams, in which steel reinforcement is completely or partially replaced by a fiberglass rod. It was established that the strength of such beams is less, but the strain is significantly higher compared to the traditional reinforced. Calculating with current standards dramatically overstates theoretical bearing capacity of these beams with composite reinforcement

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.
