The purpose of the research is the development of new methods of the estimation of the importance of scientific journals. It is known that for assessing the significance of scientific journals it is used a universally recognized impact factor, which reflects the average number of citations to the articles published in the magazine for a certain period of time. For a more objective assessment of the significance of the journal in the scientific community we use such indicator as the index of efficiency, which reflects how quickly the articles in the scientific community published in the journal become known and recognized. At the same time, the impact factor as one of the scientometric indices has inherent definite disadvantages, the main of which - the stimulation scientific edition to the artificial reduction of the number of published articles, instead of increasing demands to improve their scientific level. It is necessary to develop a method of assessing the significance of the journal for the scientific community, preserving the dignity of the impact factor and reduce its disadvantages. Application of extra scientometric indicators, in addition to the impact factor and the index of efficiency, will allow assessing the importance of the journal for the scientific community more objectively. Methodological bases of the research are: a systematic approach (considering science as a social institution in close connection with the society as a whole), metasystem approach (considering the scientific community as a metasystem, i.e. a system with a relatively independent components), qualimetric approach (considering the importance of the scientific journal as a latent variables that reflect a variety of criteria), sociological approach (considering the scientific publication as a social system, the intensity of interaction with other society)
Definition of the directions of development of transport system of the city is to ensure objectively justified needs for movement of goods and people on the territory of the city. Transport planning of the city is in direct connection with the planning of territories. The transport planning issues are resolved immediately after the planning of the city. Transport planning is based on the provisions of the General plan of the city. Organization of urban traffic should be considered as a continuous process of forecasting – planning – design – construction. In the organization of road traffic, public passenger transport should be considered as a priority, as an alternative to a car, even with a certain amount of discrimination. Among the possible solutions to the questions of organization of traffic at signalized intersections include the use of multi-program traffic lights regulation (at least three programs) that allows you to change the duration of a traffic light cycle, permitting phases at a fixed value of the cycle and intermediate cycles depending on clock download site. Equipment management systems of traffic on the road network, modern technical means of regulation. The definition of "acceptable system of urban road traffic is largely dependent on the degree of customer satisfaction (the movement). And it varies. It is influenced by many factors, such as the size of the urban agglomeration. It is quite clear that it is impossible to achieve the same results in settlements with population more than 1 million people and less than 100 thousand
Automated lighting control system designed for use in public buildings; they perform actions typical for this kind of products. Accurate maintenance of artificial light in the room at the set level. This is achieved by having a lighting control system with a photocell inside the room and controlling the lighting system illumination. Even only one this function allows you to save energy due to the cutoff of the so-called "excess light". Calculating natural light in the room. Despite having the vast majority of premises with natural lighting in the daytime, the power of the lighting system is calculated excluding. If you maintain illumination created jointly by a lighting system and natural light, at a predetermined level, it is possible to further reduce the power of the lighting system at each moment of time. At certain times of the year and hours of the day, perhaps it is enough to use just natural light. This function can be carried out by the same solar cell as in the previous case, provided that it tracks the full (natural + artificial) illumination. In this case, the energy savings can be at 20 - 40% level
The feasibility study is required in determining the effectiveness of the implementation of electrotechnical products. The main aim is to determine the magnitude of the economic effects of using key and related results in agriculture. The article presents a feasibility study of production and implementation electroactivator device in the production of 5 units monthly, 60 units per year. It is the device cost calculation based on investment, energy costs and wages. Capital investment in new plant is the cost of materials and installation. The magnitude of the value of individual elements of the unit is determined by the price lists. Determining the cost-effectiveness and technical feasibility in the production when introducing electrified units involves additional investment and operating costs, this is reflected in the cost of production. The comparison was made for the device with a new electroactivator developed in KubSAU and using chemical means of Lakmus. Calculations of economic efficiency of investments for the farm which has 225 hectares of arable land have shown that basic income will be obtained by reducing operating costs. Net present value was determined for different levels of the bank rate and inflation
In the materials of the article we mention the regularities of changes in the volume and surface solid temperature gradients and self-ventilated brake discs and illustrate their impact on the main operating parameters of the friction pairs of disk-to-pad brakes of the A 172 bus; the relationship between thermo-physical parameters of polished and matte surfaces with areas of brake discs of various types. The influence of the type of tests on the pairs of loaded with energy friction disk and pad brakes of the vehicle. We have set the intensity of heat exchange processes from the surfaces of the brake discs of various types. It is shown that this leads to increased surface temperature gradient. The volume and the surface temperature gradients of the brake discs were determined with the involvement of the hypothesis of summation of temperatures on the surface when you post the generated electric currents. It was found that in the surface layer of the working surface of a solid brake disc at its pulse heating under the influence of the temperature of the flash nucleate cracks due to the thermal fatigue of the material of the disk. The features of the design of the brake discs were considered as well. On the basis of the calculation and the experimental data we have shown a correlation between the emissivity of brushed and polished surfaces and their areas in the disk-to-pad brakes when using solid and self-ventilated discs
The intensity of drying process depends on the speed of movement of the moisture inside the object and the speed of its removal from the surface. To accelerate the drying process, temperature gradient is often regulated, which causes large power consumption. Currently, they are different methods in used for intensifying the process of drying of plant material which are physical, mechanical, chemical and electrical method. Data of literature review show a lack of data on the impact of synergies of lower frequency on the efficiency of drying plant material. Accelerating the drying process of fruit can be achieved by combining low – temperature of drying with a synergistic lower frequency of electromagnetic field. The results of the studies on the development of technologies to accelerate the drying process of mango and papaya fruit are presented in this article.
