A methodology of study of the behavior of heterogeneous systems in water–oil emulsion electrodispersion and electrodemulsification processes based on systems analysis methods is proposed. The processes occurring in the apparatuses are studied at micro (microkinetics of the process) and macro (macrokinetics of the process) levels. Physical and mathematical modeling of the process kinetics on the apparatus scales and subsequent designing of electrodispersers and electrocoagulators are accomplished making use of the obtained data. It is shown that the proposed approach allows study of the behavior of heterogeneous systems in electrodispersion and electrodemulsification processes and designing of structures and process equipment for creation and breaking of water–oil emulsion using the obtained results. © 2017 Springer Science+Business Media New York

Regularities of medium-temperature nonoxidizing pyrolysis of oily waste at a municipal solid-waste utilization installation are investigated. Dependences of the pyrolysis time on the reference loading temperature of oily wastes and their weight and moisture content are found. It is shown that the hazard class of waste at this installation decreases from high to low as a result of pyrolysis. © 2017 Springer Science+Business Media New York

The articles explore a problem of the synthesis and analyze models of subsystem "processor-memory" multiprocessor systems. The prime object is to study the architecture of the subsystem "processor-memory" of modern high-performance computing systems, calculation and comparison of the performance, as well as a conclusion on the effect of conflict over access to shared resources on the overall performance of the whole system. The objects of study of this work are the subsystem "processor-memory" multiprocessor computer systems, existing varieties of architectural construction of this subsystem. During researches the comparative analysis of systems with architecture UMA, NUMA and SUMA was carried out. Their merits and demerits were revealed. In the inference the appropriate conclusions on operation are drawn. The considered models allow making an assessment of characteristics of the multiprocessor systems without creation of a real prototype. At the expense of it economic effect as the assessment of characteristics of the designed systems and a choice of the most optimal variants can be carried out without creation of real system is reached. © 2006-2016 Asian Research Publishing Network (ARPN).

The article deals with mathematical modeling for analyzing the capacity of a multiprocessor system with Tasks Managers with the strategy of separation in space. Research methods are based on concepts of the analytical modeling theory, systems theory and queuing networks, probability theory and stochastic processes. The article presents analytical equations for the research of tasks managers with the strategy of separation in space for multiprocessor systems based on open queuing networks. The analytical part has been checked by simulation modeling. The dependence under study has been illustrated by diagrams. Finally, conclusions have been made. © 2006-2016 Asian Research Publishing Network (ARPN).

Waste-generation schemes for β-lactam cephalosporin production were compared. It was shown that effluents from chemical transformation and purification steps are the most ecologically polluted and hazardous. Therefore, the issue of reduced environmental impact must be resolved first for these process steps. In general, the technogenic load from cephalothin sodium salt production was greater than that from cephalexin monohydrate production. © 2016 Springer Science+Business Media New York

A technique of verifying the adequacy of an algorithm for estimating the polycomposition of gaseous media in terms of the adequacy of a corresponding mathematical model of a multichannel system is developed. The mathematical model is based on a previously proposed iterational process (algorithm) for estimating the parameters of a model that takes into account the totality of data in all the channels. A technique for more precise verification of the adequacy of the mathematical model, by means of which a result in the form of the confidence limits of the parameters may be obtained, is developed with the use of a dispersion approach. © 2016 Springer Science+Business Media New York

Wastewater from different stages and the average runoff in the production of cephalexin monohydrate were investigated. Comprehensive assessment of wastewater quality was proposed based on the definition of integral indicators of quality, which allows for the choice of treatment method at various stages of production and for reducing the anthropogenic load on the hydrosphere. © 2016 Springer Science+Business Media New York

A simple scheme of the noise voltage generator with a Gaussian instantaneous-value distribution and specified energy spectrum bounds is presented. The scheme is based on emitter-coupled logic (ECL) microcircuits. As reference noise, the “digital” noise of the pseudorandom number generator, which is expressed via the contents sum of the set of its adjacent bits, is used. The “digital” noise is converted into an analog voltage by adding current quanta produced by the ϰ500ЛП115 differential receivers. The main characteristics of the device are as follows: the peak-to-peak amplitude of the differential noise voltage is 600 mV and the distribution law is normal. The noise energy spectrum is bounded from above by the clock rate and from below by the number of bits of the pseudorandom number generator. In the tested prototype with a clock rate of 10 MHz, it varies from 78 kHz to 6 MHz. © 2015, Pleiades Publishing, Inc.
