PROTECTION OF PERSONAL DATA IN THE INFORMATION TRAINING SYSTEMS
DescriptionNowadays, a necessary condition for progress in the field of information technology is wide adoption of standards and technologies of information systems used for hardware and software products. Building software of computing and information systems, based on the ideology of open systems, allows to successfully solve the problems of portability on platforms of various manufacturers, the problem of interchangeability of components and, most importantly, ensures the integration of devices and users in a variety of computing and telecommunication networks. It should be emphasized the fact that to date the successful implementation of any significant projects in the field of information and computer technology, management of information and telecommunications is not possible without coordination of development with existing standards in the field of information systems and, in some cases, the development of new standards. In the transition to integrated computing and telecommunications systems principles of information systems form the basis of technology integration, the establishment of sectoral, regional and national information infrastructures and their interactions on a global scale. Therefore, we can conclude that the technology of information systems today is the working environment in which the priority is the development of information and telecommunication technologies, telecommunication and computer engineering

HYDRAULIC DESIGN OF LINEARLY DISTRIBUTED RELEASES OF STORED WATER DISCHARGES
DescriptionThe purpose of the article is to develop methods for hydraulic design of extreme discharges and water depths in critical gage lines of waterways diverting water from spillways for the accepted law to regulate linearly distributed releases of stored water discharges. The task of control for linearly distributed releases of stored water discharges is based on hydraulic design for the process of propagation and transformation of long waves described with Saint Venant equations. These equations are nonlinear and have no accurate solution in general case. To get approximate solutions they are linearized. It is established that the task of integration for these equations supposes to get their preliminary solution in the form of complete integral. Applying the complete integral theory we get analytical solution that describe the process of transformation for one direction waves moving in infinitely long prism canal of semi-bounded extent with initial uniform regime of water flow. An example of changes in both water discharge and flow depths in two fixed downstream gage lines of hydraulic works at the distance of 5000 and 10000 m from the initial gage line is presented. Hydraulic design was carried out according to the derived analytical formulas accepted as an example classical method of characteristics that is considered as analogous. Comparison of the design results on two methods allowed to determine the maximum relative error that does not exceeds 3,5 % for the design discharges and water depths. Introduction of the developed method for hydraulic design of linearly distributed releases of discharges in waterways diverting water from spillways will make it possible to optimize idle and non-technological stored water discharges

USE OF TERMS “ASU” AND “IS” IN AGRICULTURE FROM THE POINT OF VIEW OF INFORMATICS
DescriptionThe article deals with the issues of comparing the terms of ACS and IS with reference to automation in agriculture. In the technical literature, at conferences, in educational disciplines of higher education institutions, such terms as: information systems (IS), information technologies (IT), automated control systems (ACS) are often encountered. These terms are widely applied to the relevant objects in the subject areas under consideration. The area of coverage of the objects using these terms is very wide and in each case the definition of the applied term is either not specified at all considered self-explanatory, or the term is defined with various levels of detalization. In the latter case, the thoughtful researcher falls into some confusion or generally tries not to touch upon this question. In the article, on the basis of a review of known literary sources, it is shown which concepts are denoted by these terms when considering automation issues in agriculture. The subject of the study is the use of the terms IT, IS, ACS in works on automation in agriculture. The subject of the study is questions of comparison of the terms ACS and IS. The aim of the study is to indicate that automated IS is a more general concept than ACS

COLOR- SENSITIZED SOLAR ELEMENTS
DescriptionPhotovoltaic devices are a promising solution to the energy crisis, because they generate electricity directly from sunlight, without producing CO2. While color-sensitized batteries are the most studied element, mainly due to its low cost and high efficiency solar energy conversion into electricity. Until recently, the color-sensitized solar cells performance was less than 1%, however, the use of titanium dioxide as the anode material have greatly raised their efficiency. The advantages of titanium dioxide is primarily in the low cost, but its use provides high light capture efficiency, with external quantum efficiency (efficiency incident photon - charge), usually in the range of 60-90% using nanocrystal forms in comparison with

ASC-ANALYSIS OF WINE CLASSES DUE TO THEIR PROPERTIES BASED ON DATA FROM THE UCI REPOSITORY
DescriptionCreation of artificial intelligence systems is one of important and perspective directions of development of modern information technology. As there are many alternatives to artificial intelligence systems, there is a need to evaluate mathematical models of these systems. In this work, we present a solution of the problem of identifying classes of salary levels of employees depending on their characteristics. To achieve this goal it requires free access to test the source data and methodology, which will help to convert the data into the form needed for work in artificial intelligence systems. A good choice is a database of test problems for systems of artificial intelligence of UCI repository. In this work we used the database called "Wine Data Set" from the Bank's original task of artificial intelligence from repository UCI. The most reliable in this application was the model of the INF4 based on semantic, according to A. Kharkevich, integral criteria of "Amount of knowledge". The accuracy of the model is 0,916, which is much higher than the reliability of expert evaluations, which is equal to about 70%. To assess the reliability of the models in the ASC-analysis and the system of "Eidos" we used the F-criterion of van Ritbergen and fuzzy multiCLASS generalization proposed by Professor E. V. Lutsenko (L-measure)

Description
Getting the maximum number of day-old chicks largely depends on the disinfection of hatching eggs. Disinfection of eggs is important in the complex of veterinary-sanitation activities carried out in poultry farms for the prevention and elimination of infectious disease in birds. The perspective of using ozone in the poultry industry is possible due to its advantages characterized in comparison with other chemicals. It was found that ozone has the special ability to retard the growth of fungi in the biological substrates, also slows the appearance of mold on the surface of the eggshell even at 90 % relative humidity. When making parameters and modes of electro-ozonation process of egg store poultry farms there were carried out experimental studies. After ozone disinfection of hatching eggs, total bacterial contamination of shell eggs decreased by 99.89 %. The relative error of the experimental values of the theoretical amount was 7 %. As a result of production tests we set quality parameters developed by the process of electroozonation egg store poultry farms: regulation time is 8 minutes, dynamic error is 0.9, overshoot rate is 4.5%, generalized integral RMS figure is 10.6 % . The findings suggest that there is a qualitative regulation of the distribution of ozone in the egg store

MODERN METHODS AND FACILITIES OF DECLINE OF TOXIC LEVEL OF WORKING GASES OF DIESEL ENGINES
DescriptionThe problem of environmental protection from toxic contamination, i.e. toxic products contained in exhaust gases, is one of the most pressing in the modern world. Currently, internal combustion engines and vehicles of transport and technological machines rank first in power supply in the global energy balance. The total amount of pollutants released into the atmosphere by tank-automotive equipment exceeds more than three times the emissions released by industrial companies. Besides the vast majority of tracked and wheeled vehicles are equipped with diesel engines, which excel gasoline engines in harmful substances released together with exhaust gases. Therefore the problem of emission control becomes more and more urgent. The aim of this study is the analysis of modern means and methods of reducing the toxicity of exhaust gases released by diesel engines. The existing methods of emission control can be divided into four groups: improving the design of the internal combustion engine; the accounting of operational factors affecting the toxicity of exhaust gases; the use of unconventional fuels; the exhaust gases cleaning in the exhaust pipe. Each method has several major ways to reduce the emission of toxic substances, which are often mutually complementary. We have cited the research date of influencing each of the methods on the emissions of toxic substances in exhaust gases. We have found that reducing the emission of toxic substances in compliance with Euro-6 requirements can only be obtained by the simultaneous use of several methods of reducing emissions. We have proved the effectiveness and economic feasibility of using combined neutralizers to clean exhaust gases
