In work the scheme of regulation of a dynamic level of a liquid which can be used in systems of oil extracting with the purpose of increase of efficiency of their work is offered. The scheme of a regulator of the level consisting of proportional and integrated discrete elements that has allowed to reduce a static mistake is described and on the basis of to raise efficiency of regulation of a dynamic level. Modelling process of work of the offered scheme of regulation is lead, results are analysed and recommendations on parameters of a regulator are developed. Procedure of use of the offered scheme also for the control of a degree not fillings the pump is described.

Keywords: The scheme of regulation of a dynamic level of a liquid, is proportional-integrated regulator of a level, regulation of a dynamic level of a liquid in a chink, not filling the pump.

One of the priorities of socio-economic development of the municipality is the effective work aimed at improving the efficiency of territorial resources’ using, quality development, reconstruction and modernization of the network of agency of health care. In this article the problem of placement for agency of health care considers at reconstruction of urban areas. There is an environmental condition in focus, when choosing a site location of the agency of health care.

  The proposed approach to the study of social engineering systems to meet all their basic features. Blurred structure of social engineering system reflects the fuzzy cognitive model; Fuzzy connection effectively evaluated using weights Fishburne; "blur" element values system and its functioning is overcome by introducing linguistic variables and their term-set fuzzy classifiers.

  The current work considers the problem of arrangement optimization of non-convex polyhedrons into a minimal height parallelepiped container. The no-fit polyhedron based algorithm is proposed to solve described task. The no-fit polyhedrons are used not only for providing conditions of the polyhedrons mutual non-intersection but also for finding the placement points. The current paper provides the block diagrams and the pseudo code of the algorithm. Some examples and computational results are also given for public input data. 

Keywords: packing, no-fit polyhedron, non-intersection, optimization, arrangement

  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.

Keywords: questioning, semantic differential, affective component, group installation, political order, level of emotional perception

  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 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.
