A brief analysis of different approaches to the calculation and measurement of the condensation coefficient of a vapor is presented. It is shown that, on frequent occasions, calculations give values of this coefficient that are at variance with the corresponding experimental data and that the condensation coefficient is determined most exactly on the basis of the molecular-kinetic theory. It was established that the spread in the literature data on the measured values of this coefficient is explained mainly by the fact that these values were obtained not in the immediate vicinity from the boundary between the gas and liquid phases but at a large distance (as compared to the mean free path of molecules) from it. Results of calculations of the condensation coefficient of argon by the method of moleculardynamic simulation are presented. © 2014 Springer Science+Business Media New York.

The maximum likelihood method was used for synthesizing and analyzing algorithms for detection of a broadband noise pulse signal with some loosely known duration and for assessing its time and energy parameters. The effect of abnormal errors on the arrival time estimation accuracy is discussed. Computerized statistical modeling methods were used to identify the operability of the proposed detector and measurer and determine the boundaries of application of asymptotically accurate formulas for their characteristics. © 2013 by Begell House, Inc.

Modern energy efficient mechanisms of management at Russian and CIS mining enterprises are insufficient and ineffective, which is clearly expressed in most energy intensity branches of industry. Complex structure of mining, as well as incomplete systems of control, accounting and analysis of energy resources consumption are the main reasons of high energy intensity. Up to date, the issues of management of energy resources consumption, energy saving and increasing of energy efficiency have been considered only as the technical issues with obvious underestimation of usage of the management theory. For this reason, results of energy saving and increasing of energy efficiency at most enterprises are not so great as they might have been. Analysis of foreign experience in formation of organizational and administrative measures for implementation of national programs of increasing of energy efficiency in mining industry shows the important function of energy management mechanisms, based on requirements of International Standard ISO 50001:2011, by the example of uranium mining enterprises of Republic of Kazakhstan. This article considers the industry performance issues, analysis of energy consumption at certain mines, and proposed system of energy efficient mechanisms of management (based on requirements of International Standard ISO 50001:2011). There is also considered the analysis of possibility of usage of local alternative energy sources, which are prospective for application in energy isolated areas, according to the climatic conditions of region. Implementation of system of energy efficiency management at uranium mines of Republic of Kazakhstan requires the solution of the following tasks: o research and specification of natural and climatic conditions, which cause the disruptions in supplies of electric power and diesel fuel and make some difficulties in identification of the development directions of enterprises at managerial and technological levels; o systematization and realization of energy saving reserves due to implementation of organizational innovations in the form of effective mechanisms of energy management and technical innovations, aimed at improvement of energy efficiency; o development and implementation of technically and economically justified projects of alternative energy for the purpose of improvement of reliability of the enterprises functioning and reduction of dependence from foreign energy supplies in specific climatic conditions.

The development and application of the technology of reconditioning surfacing of the rollers of the bottom section of bearings with a high degree of wear of the working surface (up to 15 mm) are described. The main task was to ensure the required wear resistance of the deposited metal and HV10 hardness not lower than 500 mm2. This was achieved by the method of electric arc-mechanized surfacing with a consumable electrode wire with a solid cross section and a mixture of fluxes FKN-6 and OK 10.71 resulting in the required degree of alloying of the deposited metal and the required mechanical properties. The proposed technology is used for surfacing an experimental batch of rollers and has been tested in the actual production conditions. © 2015 Taylor & Francis.

Investigations were carried out into the conditions of free formation of welded joints in electron beam welding in the flat position with continuous penetration, and also into the dynamic model of the discharge of liquid metal of the weld pool from the root in which the metal moves downwards at a higher speed in the initial stage; but during movement of the heat source the magnitude of acceleration decreases as a result of the reduction in the width of the welded joint due to solidification and increase in surface tension forces. A procedure for determining the minimum permissible welding speed at which the welded joints can form without undercutting in the tip is described. © 2015, © 2014 Taylor & Francis.

A balance method is proposed for calculating the main characteristics of the cooling of the heat-releasing assemblies of light-water nuclear reactors in the case of repeated flooding of them at the bottom under the conditions of a maximum projected accident. The calculation data obtained by this method agree well with the corresponding results of experiments in the temperature range of up to 1200 C. The method proposed allows one not only to calculate the parameters of the flooding of a heat-releasing assembly under the conditions of an accident, but also to estimate the flow rate of the water and the time, necessary for flooding of the fuel core of a power unit in the case of its damage that is not due to the breakage of a pipe-line. © 2013 Springer Science+Business Media New York.
