In the presented article analytical methods of the solution of a task synthesis in a control system are stated. The author considers a neural network of Kokhonen which belongs to the class of networks of direct distribution. It has the only hidden layer of neurons presented in the form of a one-dimensional or two-dimensional lattice. By the author it is presented that the mechanism of cooperation realizes the principle according to which the most excited neuron strengthens (through synoptic weight) not only itself, but also spatially neurons, close to it.Article purpose - analytical methods of the solution of a problem of synthesis in a control system.

As the title implies the article describes effect of heat treatment on magnetic and mechanic properties amorphous soft magnetic cobalt-based alloy Co57Fe5Ni10Si11B17 obtained quenching from the melt. As you known, for amorphous ferromagnets are characterized by temperature instability of the magnetic and mechanical properties, which can largely degrade operation properties. To study the effect of annealing on the magnetic and physical-mechanical properties amorphous ferromagnet materials is of both scientific and practical interest, as it allows to determine the temperature application limits of the material and to optimize the magnetic properties under the influence of this factor. It is shown that heat treatment can lead to changes in the magnetic properties, and it does not cause structural changes within the resolution of x-ray diffraction. Noted the impossibility of the simultaneous receipt of all the necessary magnetic properties. After the annealing at 773 К and 823 K x-ray diffraction analysis shows a diffuse halo. Only after heat treatment at 873 K displays characteristic peaks that are the result of the last crystallization. Analysis of diffraction patterns allows us to conclude that the structural state of the alloy after heat treatment at 873 K allows us of the is responsible mixture of a solid solution based on α-cobalt and borides Co3B and (Co, Fe)2B. The crystallization temperature of the alloy according to thermal analysis is 833 K. Thus, the processes occurring in the temperature interval 373-473 are the result of topological and compositional streamlining, while increasing the annealing temperature above 473 joined by processes, resulting in fragmented appearance of fine crystalline phases. For the investigated alloy is characterized by intensive (4-5 times) reduction of permeability with frequency, which is natural in accordance with the model of damping of eddy currents. There was a trend to the re-growth of level of magnetic characteristics after annealing at 573 K.This effect is accompanied by intense embrittlement of the material. Appropriate heat treatment should recognize the annealing temperature of 473 К.

The article technical and technological “relics” in the contemporary resource use problems of the modern oil industry, connected with insufficient level of development of techniques and technologies that, in the opinion of the authors does not allow to fully start the development of mineral resources. As examples of “relics” provided drilling tools used in borehole drilling; industrial losses that occur during the development of oil fields; oil pits. Special attention is paid to the drilling instrument used in modern petroleum industry. The article also refers to developing and existing equipment. There are works of Tarasov as fundamental for the further development of techniques and technologies used in drilling. The scheme of high-pressure water monitor and the scheme of technological capabilities of water-jet technology. The new equipment allows to destroy the rocks with the greatest efficiency, thereby facilitating the drilling process. While the destruction of the breed is on the outside (hydraulic impact) and from inside (acoustically-wave destruction). Together, these processes increase the efficiency of drilling.

The choice of a rational, effective way of strengthening of foundations and bases is fundamental in the reconstruction of buildings. The strengthening of foundations of buildings means the work carried out as a consequence of the change of the geometrical dimensions of buildings, increment of permanent or temporary loads, the construction of underground facilities within the perimeter of the building, the strengthening of load-carrying ability lost as a result of suffusion, fluctuations of groundwater level and other causes, as well as resulting deformation of the structures and the wearing. Geological engineering survey and construction of the existing foundations must precede before the decision on the need to strengthen the implementation of foundations and deciding how to gain. With the help of a professional assessment of specialized companies carried out an independent examination, by means of which the results are determined by the reason of destruction of the foundation or, in the case of increasing the area of the building, are fundamental to the adoption of a package of measures needed to ensure the reliability of the foundation. Reconstruction methods are varied and the choice of a particular method depends on the factors contributing to induced damage of the foundation and the type of building and the grounds.The reliability of reconstructed buildings is provided by a joint effort of system, “base - foundation - underground construction”.

Business centers are becoming one of the most important architectural components of modern cities; the need of such centers became a demand due to the concentration of high number of businesses and international businesses within big cities, which created the demand of an architectural cluster of business centers that facilitates running business between enterprises and keep the high concentration of financial flow within one zone.To understand this concept; the article will first note the most important business centers of our modern world, the percentage of companies present, and the medium rental cost. The financial components plays a huge role when it comes to business centers; as they always need funding to be realized, and to be funded they need to be able to produce an equivalent value and profit; in other terms they need to be self-independent buildings, to be able to understand that we need to take a look at the current examples in our world.Moreover, it’s very important to understand the different types of business centers, as they provide a variety of different services not to mention the importance of understanding location requisites depending on the type of business center. In this article the main classification of business centers is explained briefly with an example.Urban requirements and importance is discussed briefly as it is important to understand the concept of CBD (Central Business District) and how it reflects on the hosting cities in many different ways. As our urban formation is changing slowly and architectural demands are changing, it’s important to plan for our future cities to fulfill the objective and create flexibility and comfort, and avoid future complication and unnecessary waste of cost.

In the article devoted to the use of environmental renewable natural material bamboo in the architecture and construction of buildings and structures. The main goal is to show architects the possibility of using bamboo in modern and traditional architecture. The main problem considered by the author: to show the advantages of bamboo compared with other structural materials defining the technical characteristics of the bamboo, to consider the basic architectural-constructional units and parts for structures made of bamboo. The author carries out an analysis of the work of architect Simon vélez and Simon Ocie Samper, which create the architecture by bamboo, with the use of computer aided design in construction. In the article notes that the modern design of the buildings and structures with bamboo has changed, in comparison with traditional notions of form. The application of new computer technologies allowed to carry out complex calculations and it was possible to exercise much more freedom in creating original forms.
