This work deals with the study of atomic and electronic structure of kaolinite samples (Glukhovtsy deposit) and montmorillonite (Millerovsky deposit) by density functional theory. The applicability of existing exchange-correlation potential in the local density approximation (LDA) and the generalized gradient approximation (GGA) is analised for an adequate description of the physical properties of layered aluminosilicate. An experimental and theoretical study of the IR spectra of minerals, as well as the identification of the most intense absorption bands, performed in the approximation of DFT using the exchange-correlation potential PW91. The analysis of the band structure of these minerals, which showed that these compounds are direct-gap insulators.

Is devoted to the actual problem of constructing classifiers objects given by a point in a multidimensional space of feature values. The principle of linear normal classification of objects in multi-dimensional space of attributes can be used to build a classifier in the case of many complex structures, in general, are inseparable one hyperplane. In such cases, proposed to use a set of hierarchically related normal separating hyperplanes, which is called the normal hierarchical classifier.

Keywords: recognition, classification, feature space, the geometric method

Promising absorbing materials along with a Ni-Zn-ferrites are Mg-Zn-ferrites, as they are also intensively absorbs electromagnetic waves in the frequency range from 50 MHz to 1000 MHz. The main advantage of the Mg-Zn-ferrite is used as an inexpensive raw material magnesium oxide. The paper presents the results of research to improve the efficiency of broadband radio-magnesium-zinc ferrite by increasing the contribution of the dielectric loss. The influence of alloying elements of the atmosphere gas and cooling after the sintering thermal radiation by absorption of electromagnetic waves. Confirmed cooling efficiency of products after sintering in an atmosphere with reduced oxygen partial pressure to increase the dielectric constant. A model is proposed to explain the increase in the dielectric loss ferrite during cooling in a reducing atmosphere.

This paper studies the dependence of the ratio of prismatic strength (Rb) from cube strength (R) for high-strength concrete of classes B70 ... B110. Experiments were carried on the concrete cubes with an edge of 150 mm and prisms with a base 150x150 mm and a height 600 mm. The tendency to reduce the ratio Rb / R with increasing strength of the concrete is founded. A new relationship Rb = f (R) is offered

The paper proposes a new relationship for the analytical description of the diagram «b–b» for high-strength concrete of classes C55/67 ... C90/105. The formula developed on the basis of the accepted in EU relation of Sargin and agrees well with the experimental data. A new relation of the ultimate relative deformation of concrete from the strength is developed

In our country creation of country housing real estate was slowed down due to the lack of necessary infrastructure, and also high level of cost at its creation. The main factor promoting development of mass low housing, existence of the corresponding infrastructure and necessary communications, and also in certain cases objects of social infrastructure is.
  It is impossible to forget and the problems arising by consideration of potential of development of low housing: infrastructure dilapidation; small number of free land fund; complexity of preparation of infrastructure of the territory; difficulties in search of financial resources; small susceptibility of branch to innovative processes.
  The scientific logistic model of the organization of the mass low housing construction, considering creation of necessary objects of infrastructure for building is offered. Now need of strategically planned coordination of business and the state is the only way to the solution of infrastructure and other tasks connected with development of low housing construction from developers and builders.

In recent years reconstruction of buildings and constructions became one of the main directions in the field of construction. Considering that at reconstruction capital investments it is significantly less, and payback is higher, than at new construction, the share of capital investments in reconstruction will increase.
It is necessary to apply intensive methods of repair and reconstruction of buildings and constructions as one-time costs of reconstruction and repair there are less than one-time costs of new construction in construction production. Considering a significant amount of the factors significantly influencing the organization of construction at reconstruction of buildings and constructions, previously before development of organizational and technological documentation it is necessary to prepare the list of the data necessary for the organization of construction works and to make their analysis which concerns the analysis of projects and the territory of a building site, including situational plans.

The article presents the results of calculations of reinforced concrete columns of high-strength concrete on the SNiP and SP. Compared the results with experimental data. The proposed adjustment formulas used with correction factors k and w resulting standard deviation of the bearing capacity of the columns from the experimental reduced more than four times.

Discusses the main changes in kolorostike residential interiors in the period from 2003 to 2013 on the basis of analysis of works by Russian disigners. Whole Russian interior designers have lost some identity. Changing the color palette for the interior, executed in the style of "Art Deco", "modern", "fusion". Novation - "Ecostyle" and interiors in a light-color installations. Basically, the color palette has become more complex and sophisticated, perhaps less distinctive.
