Intensification of heat transfer processes is an important and relevant task, and one way to solve it is the use of liquids with various nanoparticles, called “nanofluids.” Therefore, an experimental study of the convective heat transfer of nanodiamonds suspensions in a circular straight pipe was carried out in this paper. Ethylene glycol was used as the base liquid. The concentration of nanoparticles ranged from 0.25 vol.% to 2 vol.%. The Reynolds numbers varied from 5 to 100. The values of the viscosity and the thermal conductivity coefficients of the resulting nanofluids were also measured experimentally. It was found as a result of these measurements, that the dependence of the thermal conductivity on the concentration of nanoparticles is described by the Maxwell equation. The dependence of the nanofluids viscosity coefficient on the nanoparticles concentration was significantly differ from the Einstein equation, it was much higher. It was found as a result of experimental studies of convective heat transfer, that as the concentration of nanoparticles increases, the heat transfer coefficient also increases, and for a maximum concentration, it was 15% higher then for the base fluid.

The article examines the effectiveness of the scheduling algorithm for solving the problem of increasing the efficiency of the operation of corporate information and computer networks based on the use of priority information processing models. The possibility of increasing the efficiency is caused by the analysis of the features of properties and characteristics of the considered network in various modes of operation, which are obtained at the modeling stage. The order of servicing of information flows of different types, determined by the introduction of priorities, allows to reduce the average waiting time for system operation and loss due to waiting. The task of analyzing of the efficiency of priority systems for the transmission and processing of information in complex information and computing systems is the perspective application-oriented task due to use of an effective dispatch algorithm.

In last decades on of Russia Railways are phased implementation and upgrade systems of technical diagnostics and monitoring railway automation and telemechanics. The implementation systems of technical diagnostics and monitoring allows to move from the regulatory type of maintenance, which takes a significant time of operating personnel to factual, which will reduce operating costs. Due to fact that maintenance by condition is reduce to a minimum interference in operation of railway automation and remote control, it is possible to reduce number so-called post-prevention failures. For ensuring continuity and safety transportation process system of power supply devices railway automatic equipment and telemechanics solve important and responsible problems from which it is possible to distinguish providing uninterrupted, that is continuous in time, power supply systems of railway automatic equipment and telemechanics and devices with quality of electric power, necessary for their reliable work. As constructive, circuit and technological capabilities of increase in reliability of systems are limited, a natural way of elimination of this shortcoming is development methods and control devices working capacity and search malfunctions of equipment. Thanks to the microprocessor systems introduced on Russian Railways opportunities for solution problems of diagnosing have extended.

Reduction of negative consequences of large scale system emergencies with cascading development together with massive loss of supply of consumers and fast system restoration are possible by using distributed generation. Actual problem in this case is to keep the transient stability of distributed generation units because of rather small inertia parameters of such small installations, especially gas turbine units, by the emergencies. The importance of this problem is higher for operation control of smart grid.

The paper represents the model of AC drive control system. An analysis of conventional drive control system has been performed, its advantages and disadvantages, and preconditions for use of intelligent approaches for implementation of control systems for this kind of objects have been estimated. The intelligent system is supposed to be modeled with use of fuzzy logic controller and different inference algorithms for implementation of control laws in various control loops. Dynamic characteristics of the system both for conventional case and with use of controllers based on fuzzy set theory have been analyzed. The practicability of using the multi-cascade fuzzy systems while implementation of unified intelligent control module and different combinations of fuzzy inference algorithms has been demonstrated for complex drive systems. Application of this technology allows implementation of control system for the entire class of drive systems considering all special aspects and relationships between the coordinates in the complex control object. Additionally, modeling of spacial membership function using multi-cascade fuzzy controller will give a possibility to avoid a variety of quantitative and qualitative restrictions due to complex relations between the coordinate in such systems.

The technology of measurement and control of geometric parameters of large-sized parts in heavy and transport engineering, in power engineering, etc. is considered in this paper. It is based on the results of measuring the radial and axial run-out of the surfaces of the part and the subsequent processing of this primary measurement information, without requiring the accuracy of the output base. This can be comprehended by bringing the results of radial and axial run-out measurement to the virtual output datum - to the virtual datum axis, which is a straight line passing through the centroids of points of instantaneous rotation axes in sections of two rings mounted on the end face surfaces of the part approximately coaxial to its geometric axis.

We have developed mathematical models of reliability of power supply systems for various type consumers. These models take into account the sensitivity of consumers to specific disturbances, specific of networks exploitation and possibility of redundancy. The technique results are to determine the ways of the operational dependability improving. We suggested the directions of electrical networks dependability increase by using superfluity of consumers' reliability redundancy and the installation of protection devices for voltage dips.
