- ДокументEVALUATION OF INDUCTANCE WITH ELECTRICAL WIRES(2016) V. KudryIn this paper proved the possibility of developing passive electronic inductive elements based replace metal wire that is wound inductor, the wire is made of electret. The relative permeability of the electret S 10 000, several orders of magnitude greater than the permeability of conventional insulation materials, i < 10, resulting current in the wire acquires properties bias current. The essence of innovation is to replace the source of of magnetic induction flow that pervades the core of the coil. According to the theory of electrodynamics, current bias, in contrast to conduction current, generated no movement of charge along the wire, but the change of the charge in the local volume.Equivalence bias current and conduction current is manifested in the possibility of forming a magnetic field. The flow through magnetic induction coil core regardless of the current it generates, creates voltage at its ends.The paper also shows the numeric characteristics that determine the effective frequency range, specified the reason why electric a wire with і < 10 can not generate magnetic flux through the core and serve as a passive reactive component.

GurskyThe question of implementation of the interface between the DCNET and Flash media is examined. Usage of the interface-based DCNET environment allows to reduce time and material costs for the development t and study of complicated technological system and to increase functional imaging capabilities compared to ActionScript.
- ДокументINCREASING OF PRECISE ESTIMATION OF OPTIMAL CRITERIA BOILER FUNCTIONING(2016) Y. M. Skakovsk, A. V. Babkov, E. V. MandroResults of laboratory and industrial research allowed offering a way to improve the accuracy of estimation the optimal criterion of boilers' operation depending on fuel quality. Criterion is calculated continuously during boiler operation as heat ratio transmitted in production with superheated steam to the thermal energy obtained by combustion in boiler’s furnace fuel (natural gas) .The non-linearity dependence of steam enthalpy from its temperature and pressure are considered when calculating, as well as changes in calorific value of natural gas, depending on variety in nitrogen content therein. The control algorithm and program for Ukrainian PLC MIC-52 are offered. The user selection program implements two searching modes for criterion maximum: automated and automatic. The results are going to be used for upgrading the existing control system on sugar factory.
- ДокументAUTOMATION OF THE RESIDENTIAL BUILDING WATER SUPPLY SYSTEM PUMPING STATION(2016) A. M. KuliaEssence of process of water-supply of apartment dwelling house is considered. The existent state over of automation of the pumping stations is brought. The task of development of the effective system of automatic control is put by them. Possibility of decision of task is shown by the use in the system of frequency transformer that feeds the electrodrives of pumps, and also due to perfection of algorithms of the pumps rotation frequency adjusting and logical management of their switching a sequence. The practical value of the use of the system is to increase dynamic.
- ДокументMODERN ELECTRIC CARS OF TESLA MOTORS COMPANY(2016) O. F. Vynakov, E. V. Savolova, A. I. SkrynnykThis overview article shows the advantages of a modern electric car as compared with internal combustion cars by the example of the electric vehicles of Tesla Motors Company. It (в смысле- статья) describes the history of this firm, provides technical and tactical characteristics of three modifications of electric vehicles produced by Tesla Motors. Modern electric cars are not less powerful than cars with combustion engines both in speed and acceleration amount. They are reliable, economical and safe in operation. With every year the maximum range of an electric car is increasing and its battery charging time is decreasing.Solving the problem of environmental safety, the governments of most countries are trying to encourage people to switch to electric cars by creating subsidy programs, lending and abolition of taxation. Therefore, the advent of an electric vehicle in all major cities of the world is inevitable.

- ДокументPROBLEM TOPICALITY OF OFFSET ABSENCE ORDER INCREASE IN CONTROLLERS DURING CONTROL OF OBJECTS WITH VARYING TRANSMISSION COEFFICIENT(2016) A. V. Khobin, M. V. LevinskyiNon-stationary control objects, especially with varying transmission coefficient, are fairly common in practice. Creation of automatic control systems (ACS) for them is topical issue. This task of creating ACS for these kind of control objects is more difficult than for stationary control objects (with constant parameters) because process value deviations relative to set point value are caused not only by coordinate disturbances but also by parametric ones. The issue of offset absence order increase impact on the levels of stabilization and reference tracking errors traditionally is dealt with when making synthesis of stationary ACS, particularly follow-up and program systems. For analytical solution of the non-stationary ACS analysis and synthesis problems, which contain control objects with varying transmission coefficient ko(t), it is necessary to utilize mathematical methods of linear systems with varying parameters. They are based on the concept of parametric transfer function. At the same time analytical calculation of stabilization and reference tracking errors, even for steady processes, is, apparently, extremely difficult, because there were found no examples of solution to this problem in technical publications. Computer modeling is considered more productive. It does not allow to obtain analytical expressions for control errors. But computer experiment goal planning allows to mark out their basic features and to evaluate effective methods of decreasing these mistakes.

LisiukThis paper considers an example of solving the problem of single-dimensional cutting optimization. It is shown that elements of the theory of genetic algorithms can be used successfully for its solution. A distinctive feature of this task is the next: a set of parts and profiles, which the parts are cut from, does not change in the search for solutions but their sequence order changes. Results of the solution were used to write the ‘dll’-library easily integrable into various application software.
- ДокументSTATEMENT OF THE OPTIMIZATION PROBLEM OF CARBON PRODUCTS PRODUCTION(2016) O. A. ZhuchenkoThe paper formulated optimization problem formulation production of carbon products. The analysis of technical and economic parameters that can be used to optimize the production of carbonaceous products had been done by the author. To evaluate the efficiency of the energy-intensive production uses several technical and economic indicators. In particular, the specific cost, productivity, income and profitability of production. Based on a detailed analysis had been formulated optimality criterion that takes into account the technological components of profitability. The components in detail the criteria and the proposed method of calculating non-trivial, one of them - the production cost of each product. When solving the optimization problem of technological modes of production into account constraints on the variables are optimized. Thus, restrictions may be expressed on the number of each product produced. Have been formulated the method of calculating the cost per unit of product. Attention is paid to the quality indices of finished products as an additional constraint in the optimization problem. As a result have been formulated the general problem of optimizing the production of carbon products, which includes the optimality criterion and restrictions.
