- 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.
- ДокументA FUNCTIONAL MODEL OF THE INFORMATION TECHNOLOGY FOR MANAGEMENT OF NATURAL EMERGENCY SITUATIONS ON TRUNK ROADS(2016) N. Fil’A functional model of the information technology for management of natural emergency situations on trunk roads has been developed on the basis of the IDEF0 notation. The functional model of the information technology for management of natural emergency situations reflects the causal relationships between objects and operations.
- ДокументGENETIC ALGORITHMS APPLICATION TO DECIDE THE ISSUE OF SINGLE-DIMENSIONAL CUTTING OPTIMIZATION(2016) N. A. Belova, G. P. 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.
- ДокументABOUT SIGNIFICANCE OF THE CONTROL PROBLEM OF ECOLOGICAL EFFICIENCY OF FUNCTIONING OF TECHNICAL OBJECTS(2016) S. A. VoinovaIt's noted the current stress state of the natural environment due to the increasing harmful effects of the developing global production. It's indicated on the urgency to fully reduce the harmful effects of production. It's shown the control operation TO is highly efficient and productive means of improving the environmental performance of production. It's described the main features of management of ecology, created as well as existing worn out. It's shown the real possibilities of the use of management tools as a highly productive universal environmental funds.
- 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.
