  • Operando dynamics of the nanoscale atomic and electronic structure of materials for hydrogen storage

    We have carried out the analysis on the scientific and technological literature on methods of calculation and analysis of the x-ray diffraction, x-ray absorption and Raman spectra used to analyse the structure of the materials for hydrogen storage under realistic operating conditions. The simulations were carried out for the series of small palladium nanoclusters with embedded hydrogen. Multiscale computer modelling was used to simulate the dynamics of structure of the materials during charge/discharge phases.

    Keywords: hydrogen storage, XANES, x-ray diffraction, Raman scattering, fuel cell

  • Re-entrainment decrease in electrocyclone

    The article presents the results of experimental research of the re-entrainment reduction in the electrocyclone. The authors shows an increase in the collection efficiency of ash up to 99.5% and reduction of entrainment in 4 times when profiled elements was install  on collection electrode surface

    Keywords: gas dust cleaning, electrocyclone, re-entrainment, collection efficiency, ash from thermal power plants

      The proposed approach to the study of social engineering systems to meet all their basic features. Blurred structure of social engineering system reflects the fuzzy cognitive model; Fuzzy connection effectively evaluated using weights Fishburne; "blur" element values system and its functioning is overcome by introducing linguistic variables and their term-set fuzzy classifiers.  

    Keywords: system analysis, poorly structured and poorly formalizable processes, sociotechnical systems, fuzzy cognitive modeling

      This article analyzes the condition of the vehicle driver by methods using data RR-interval time series implementing wavelet-transform. The results of the discrete Wavelet-transform with the Daubechies wavelet of the fourth order are considered.

    Keywords: wavelet-transform, RR-interval series, interval diagram

  • Synthesis of protein products. Receipt of black caviar

    In article possibility of reception of an artificial foodstuff, in particular, artificial black caviar, both in laboratory, and in a life with a view of creation of is minimum necessary conditions for preservation of a life and health of people in extreme situations is considered. Initial products is foodstuff with application of the harmless components applied in the food-processing industry, as dyes.

    Keywords: Caviar black, gelatin, cod-liver oil, a herring brine, , silver nitrate

    The question of increase of efficiency of the cooling process in the compression refrigerating machines and household refrigerating appliances. Describes a new original method of cooling of the condenser vapour-compression refrigeration machines, which is due to wet the surface of the capacitor with its further blow. Shows the complexity of the theoretical analysis of the proposed method of cooling and substantiated the necessity of experimental studies of the process of cooling of the refrigerant in the capacitor. 

    Keywords: compression refrigerator, evaporative a capacitor, a new method of cooling refrigerant, energy performance, the efficiency of the cooling

  • The reasons of occurrence of interval values in mathematical models of robust research the stability of control systems

    Examines the historical stages in the development  of the theory of systems research management of the uncertainties, the reasons for they arise in the mathematical  model, this is reflected in an interval values in the transfer  function of the object of control. It is proposed algorithm for obtaining experimentally the interval of values.

    Keywords: interval values, robust stability, the transfer function, parametric uncertainty, a mathematical model of the management system

  • Specification of a technique of definition of a charge of drop ablation in a working zone at barbotage electrolits

    In article questions of improvement of a technique and theoretical bases of electrocatching with reference to problems of fight against drop ablation in a working zone in the conditions of galvanic production are considered.

    Keywords: electrocatching, drop ablation, working zone, barbotage, charge, drop

      Semicars, as is known, are a universal rolling stock. For today in RZD and in transport HIGH SCHOOLS of the country works of research character on regulation and operation optimization by a universal rolling stock are actively conducted. In article a task in view on optimum control empty cars of various patterns of ownership with use of a transport problem.

  • Increase of system effectiveness of two - stage transportation: on an example of management of a solid municipal waste

    The model of increase of efficiency of the created system of transportation of a municipal waste is presented. Need for carrying out modeling and the actions connected with reorganization of system, because of possible increase in total expenses is proved at shift of positions of reloading stations of rather optimum points owing to local conditions of the territory of municipality.

    Keywords: a solid municipal waste, technological process of transportation, two - stage transportation

  • Use of an inversion multidimensional classification in conceptual design

      The article is devoted to the methodology of construction of fields of knowledge through the use of procedures inversion, allowing to most fully present the essence of the studied object, its inner content, expressed as a unity of diversity contradictory properties ensuring its integrity required for the generation of new knowledge as an increase to the number of criteria for the classification and, accordingly, the space of the classification.

    Keywords: conceptual design, fields of knowledge, classification, inversion

  • Rheology salt massif with a spherical cavity

    This article is related to technological problems of cavities with kamufletnyh explosions, during which the temperature in the cavity greatly exceeds the initial temperature of the array. Often these cavities are created in an array of rock salt. Because the salt even at light loads demonstrate expressive flow properties, it is interesting solution to the problem of creep salt massif with a cavity under the action of a force (pressure inside the cavity and the pressure of the soil), and thermal loads.

  • Tools to support the modeling process, which is based on L-systems

    It is proposed software-technological complex for modeling, which uses L-systems (Lindenmayer Systems) as the tools of modeling and visualization. The main purpose is to construct models of processes and structures that have a fractal nature. The complex supports different types of L-systems: deterministic context-free L-systems, stochastic L-systems, parametric L-systems, context sensitive L-systems. The developed tools have been used to model and analyze the socio-economic processes.
