The use of microprocessor devices for relay protection and automation, devices for measuring and determining electric power quality permits the introduction and development of digital circuits leading from primary current and voltage transformers. The use of optical channels for digital circuits addresses the problem of offsetting electromagnetic interference and voltage shift. Creating optical and digital current and voltage transformers with digitization of signals already at high measuring transformer voltage is the best solution for the above problem of mechanical engineering in the field of electromagnetic compatibility of high voltage measuring transformers. However, a difficulty arises in ensuring electromagnetic compatibility of sensors and microelectronic equipment adjoining live parts. The present study is devoted to examining the impact of electromagnetic fields on sensors and solving the problems of electromagnetic compatibility of optical and digital current and voltage transformers. © Published under licence by IOP Publishing Ltd.

We re-address the problem of construction of new infinite-dimensional completely integrable systems on the basis of known ones, and we reveal a working mechanism for such transitions. By splitting the problem's solution in two steps, we explain how the classical technique of Gardner's deformations facilitates-in a regular way-making the first, nontrivial move, in the course of which the drafts of new systems are created (often, of hydrodynamic type). The other step then amounts to higher differential order extensions of symbols in the intermediate hierarchies (e. g., by using the techniques of Dubrovin et al. [1, 2] and Ferapontov et al. [3, 4]).

This paper describes recent studies devoted to the problem of modeling the solid-fluid interaction in partially filled liquid containers. This problem is of much importance for numerous applications, including those in the airspace industry (rockets, satellites), road and naval transportation, and has become in recent years an object of keen interest from researchers. The paper focuses in particular on the sloshing phenomenon and on the numerical approaches used to predict the sloshing wave amplitude, frequency, pressure exerted on the walls and the effect of sloshing on the stability in the container environment. Recent publications devoted to sloshing and fluid-structure interaction are reviewed and the numerical methods used in then are exposed and classified according to the problem formulations employed. They concern primarily finite-elements and finite-differences methods applied to Euler or Lagrangian fluid and solid domains, as well as the smoothed particle method. Issues related to modeling the free-surface of the fluid, fluid-solid interface and to numerical coupling are exposed. Results obtained by various numerical methods are discussed in comparison with experimental results, where possible. Applications of sloshing models in naval, aerospace and other industries are described and discussed. © 2010 Elsevier Ltd. All rights reserved.

Higher-order moments of particle size distribution functions are determined for magnetic fluids from analysis of initial segments of magnetization curves. It is shown that the higher-order moments calculated using approximation of real particle size distributions by the Γ distribution are strongly overestimated. Agreement between the measured and calculated moments can be radically improved by truncating maximum particle size Xmax. A relation between Xmax and the parameters of the Γ distribution is proposed taking into account the degree of polydispersity of a magnetic fluid. Namely, the ratio between the maximum and most probable particle diameters is equal to the ratio between the mean-square magnetic moment of a particle and its squared average magnetic moment. © 2016, Pleiades Publishing, Ltd.

The increased requirements to the quality of the water heat conductor for working superhigh (SHP) and supercritical (SCP) pressure power plants and promising units, including combined-cycle gas turbine (CCGT) units and power plants with ultrasupercritical parameters (USCPs), can largely be satisfied through specific electric conductivity and pH measurements for cooled heat conductor samples combined with calculations of ionic equilibria and indirect measurements of several specified and diagnostic parameters. The possibility of calculating the ammonia and chloride concentrations and the total concentration of hardness and sodium cations in the feed water of drum-type boilers and the phosphate and salt contents in boiler water was demonstrated. An equation for evaluating the content of potentially acid substances in the feed water of monotube boilers was suggested. The potential of the developed procedure for evaluating the state of waterchemistry conditions (WCCs) in power plants with CCGT units was shown. © 2016, Pleiades Publishing, Inc.
