Energy control and grinding mechanoactivation planetary mill AGO-3
Abstract
For laboratory mehanoaktivatora AGO-3 the parameters of thermal and energy intensity depending on the level filling the container carrier velocity, time mechanical activation. Determine the power delivered to the grinding bodies, friction losses and hydraulic resistance movement of the containers. The reported study was funded by RFBR according to the research project No. 15-42-00106.

Phase formation in the combustion wave of SHS by diluting quartz equiatomic system Ni-Al
Abstract
Research of «hardening» of the structure in the Ni-Al system equiatomic composition with the addition of quartz at a stop wave SHS combustion. Revealed several zones with characteristic microstructure, which allowed to establish a fol-lower - of phase formation during the formation of nickel aluminide initially heating the reaction cell in the process of SH-synthesis.

The assessment of the suitability of synthetic humic acids in the production of cellular concrete
Abstract
Investigated the suitability of the synthetic humic acids as foaming agent in the production of aerated non-autoclaved concrete. It is shown that in aqueous-alkaline solutions of humic acids tend to form hardened pins and can be recommended as surface-active substances in the production of aerated concrete.

Experimental studies on emergency processes in real time Impulse Power Conversion Systems
Abstract
This article describes an experimental system for studying the dynamics of impulse power conversion systems. The peculiarity of this experimental setup is due to the implementation of the analysis of time series of synchronized in real-time through the use of microcontrollers STMicroelectronics and National Instruments firms.

On the use of the structural and functional modeling of a system analysis of the company financial statements
Abstract
The article discusses the construction of complex models consisting of a structural-functional model, information model and semantic data model, which is the basis for the design of soft-ware that implements the method of calculating the dynamic standard. Dynamic specification of linear and non-linear form is intended for financial and economic analysis of the performance of the enterprise. Dynamic standard to some extent reduces the impact on the results of financial and economic analysis of the experience and skills of the analyst conducting this analysis.

Computer simulation of pedestrian flows in the biathlon center
Abstract
We construct a simulation model for pedestrian flows allowing to solve the problems of calculation of flow capacity of a stadium, to consider different configurations of physical space and pedestrian zones, to provide statistics information for pedestrian flows, and to visualize statistics in the form of maps of densities of pedestrian flows. The model is realized with the use of the software bandle AnyLogic.

Formal Concept Analysis (FCA) in socially-oriented geoinformation systems
Abstract
This article describes how to use capacity of the theory of formal concept analysis (AFP) to create a mathematical model of information resource focused on people with disabilities. Describes methods of constructing formal concept grids using Galois operators in relation to data socially-oriented geographic information systems (GIS).

Methot of real-time failure process identification in pulse energy conversion system
Abstract
The task of real time identification of pulse energy conversion system state is investigated in this work. Algorithm of identification of the pulse energy conversion system state is described and experimentally tested. The designed algorithm provides determination of the main process period of the pulse energy conversion system.
