The optimization of the factors affecting the efficiency of Electro-activation of foam concrete mixes is carried out. For this purpose was applied mathematical planning experiment. As varied factors adopted grain size of sand grains, the value of the applied voltage and the duration of treatment. The mathematical models for strength, high density and structural quality are obtained.

Keywords: Variable electric field, foam-concrete mix, coefficient of structural quality,

The paper considers arbitrarily supported arbitrarily loaded reinforced, beam with an aggregate of bimodulus of elasticity material. Formulas for determination of the tangential stresses arising in the aggregate, subject to the reinforced elements. Formulas are obtained for principal stresses occurring at an arbitrary point in the aggregate, as well as the equation for determining the point where major stresses reach extreme values. Are terms of strength as the classical theories of strength, and strength criteria applied for calculation of constructions made of bimodulus of elasticity material.

Keywords: reinforced beam, bielastic modulus, stress, normal concrete, strength criteria.

In the article the types of the tubes, used for transportation of hydrocarbon resources on oil and gas fields of West Siberia are considered. the analysis of the statistical data and materials on the corrosion protection in the West-Siberian region is also provided in the article. moreover, the most optimal and effective ways of corrosion protection using the tubes of high corrosion resistance are introduced in the article.

There are principles that are included in the basis of common information space. The most of all principles are relevance, predictability, specific, response time, institutional, security. The article consider technical aspects such as the distribution of computing power on the basis of the properties of parallel processes, systems requirements (scalability, distribution), logistics principles of information flow, the implementation of the functions of information processes. The article describes the technical, economic and legal basis of common information space. Since railway trasnport includes a number of developments, the implementation uses the principles of reengineering such as optimality, adaptability, redundancy, rationality, vertical, horizontal, intensity etc ...

The results of the heat transfer processes studies in the heat exchange borehole (BHE), equipped with coaxial collector in order to establish the influence of its design parameters, the properties of the rock mass, mode and duration of the coolant flow to the effective temperature difference. The resulting analytical equation for the effective temperature difference in the conditions of unsteady heat transfer experimentally verified in a lab BHE and can be used in the design of these BHE systems in specific geological and technical conditions. Use the resulting equation for the inverse calculation can be counted the diameter and the depth of the BHE, as well as the duration of the coolant circulation in the coaxial collector. The advantage of such approach is the consideration of the main factors that influence the of the effective temperature difference.

  Various non-invasive assessment of psycho-physiological and emotional state were analyzed: the fractal estimation of speech signals, the analysis of rhythmic EEG patterns and computer stabilometry. The results allowing  prediction of the transition of the individual in a particular state, were obtained and objective criteria for determining the individual personality as a specialist were identified.

  In this paper we consider the application of digital signal processing techniques to clean them from interference and to present in a special basis, which allows the detection of events related to the manifestation of the functioning of a functional system in health and disease. Implemented mathematical foundation and rapid synthesis methods for converting the signals used in electrophysiology based on the discrete wavelet and Gabor transforms. Filter synthesis using Filter Desing ToolBox package MatLab was observed.
