METHODS OF WAVELET ANALYSIS AS A TOOL OF ECONOMIC SECURITY
DescriptionIn the context of the objective existence of risk and economic, human and other losses related with it, there is a need in a specific mechanism, which would allow the best way to predict the damage caused by the emergency. These risk management tools in emergency situations are monitoring and forecasting. In this research work, time series are used as a signal; they contain information about the number of fires in the Karachayevo-Cherkessia in the period of 1983- 2014. In solving the problem, the authors applied wavelet tools for data cleaning from noise, anomalies that have provided quality model building reliable forecast - possible number of fires in one quarter ahead. This example shows that for the construction of this forecast there is no need for a rigorous mathematical model specification, which is especially valuable in the analysis of poorly formalized processes. We have noted that most of the tasks in emergencies fall into this category of processes

Description
We have illustrated multiple factor analysis of the dynamic friction coefficient of the friction units in tribosystem and tribounits under laboratory conditions. As the tribosystem we had a model band-block brake with regime parameters of the control handle tension of the brake and brake work. By using the method of the mathematical planning of the extreme experiments, we have obtained functional dependence of the dynamic friction coefficient of the variable parameters in the form of a second-order polynomial, which adequately describe the processes under study. As tribounit at the micro- and nanoscale there was the reference change of the dynamic friction coefficient of the pair "Retinax FC-24A – Steel 35HNL" as a function of surface temperature, the values of which correspond to certain laws, based on the rise and fall of the characteristics of the dynamic friction coefficient. We have made the evaluation of the dynamic friction coefficient on the principle of the superposition with the multiple factor analysis of the following parameters: the process of forced cooling and heating; the processes of the polarization and depolarization in the contact patch of the micropoints of friction pairs; the type of the contacts of the micropoints depending on the work function of the electrons and ions from materials; the formation of primary and secondary structures on the surfaces of frictional contact; the destruction and restoration of the pellicles on surfaces, etc. We have analyzed the results of the studies of changes of the dynamic friction coefficient on the macro-, micro- and nanoscale and we have found the basic factors affecting its value

MOBILE POLLINATION AS A PARADIGM FOR INDUSTRIAL BEEKEEPING
06.00.00 Agricultural sciences
DescriptionThe article analyzes the state of the domestic beekeeping. It is proposed, as a paradigm of the industrial beekeeping, to use honey and pollination systems. Over the past 25 years, because the hard economic reforms in the public sector, there was almost double reduction of honey collection. Russian beekeeping is in the hard situation because of the low yields and the use of outdated technologies. Russia's share in the global honey market does not exceed 1 %. A more viable was apiaries of private households. Beekeepers receive a basic income from the sale of honey. Meanwhile, in developed countries more than 60% of the income of integrated use of honeybees account for pollination activities. In modern conditions of the Russian vector of development of beekeeping should be its production and technological re-equipment, improving its bioecological principles and socio - economic transformation of the infrastructure sector. Using mobile honey- pollination systems, which provide bees with feed conveyor due to the frequent movement of the apiary, honey plant and beekeepers can reduce the cost of manual labor for loading and unloading hives. In the Kuban Agrarian University we designed the pavilion design (RF patent number 2,284,103 ), awarded with a silver medal of Concours Lepine (France, Paris ). Using a mobile pavilion allows to conduct all production functions: honey and pollination production and reproduction, ensuring the competitiveness of the industry

MODEL OF THE CITY IN THE KNOWLEDGE ECONOMY
DescriptionThe known models of the city from a position of knowledge economy are analyzed in the article. The hypothesis of the research shows that practice of a strategizing of the city has to be based on polymodel approach when several key models adequate to modern trends are taken as a basis, connected with formation of sector of economy as a part of regional social and economic system, and other models are addition and essential extension of the contents chosen basic models, strengthening their cognitive component. Research of the model of a creative city, creative clusters, quarters and zones of the city, model of the digital city, model of an eco-city is conducted. Substantial features of models are revealed. It is established that the informative potential of types of models of the city increases on the basis of research and identification of mechanisms of mutually transition (participation) of elements of one model as elements another (others) complementary models. The city as the semistructured system consisting of diverse subsystems and elements does not submit to rational planning owing to structural and territorial duplication of functions and asynchrony in functioning and changes, and also owing to the history and sociocultural specifics of the population significantly giving immanent logic of life. It is necessary to create flexible system of the city strategy on a polymodel (interdisciplinary) basis, based on activization of growth sources, various on contents, for the purpose of formation of new image of the cities

Description
Fracture geometry depends on stresses and rock properties in hydraulic fracturing operation. Poisson’s ratio imports directly in the calculations related to formation stresses. The most important reason for limiting fracture height is the natural stresses contrast resulting from the differences with Poisson ratios. Without this difference, fracture would have largely uncontrolled height. The goal of this study is mathematical investigation of the effect of Poisson’s ratio on the formation stresses that is necessary to select value of breakdown pressure in hydraulic fracturing operation. In this article, a mathematical model has been coded using “MATLAB” software for prediction of stresses in the various layers. This designed program is able to present both digital and graphical output results for different values of Poisson’s ratio. At the end, stresses exerted on the different layers of the several real oil reservoirs have simulated and breakdown pressures have determined

DEFORMATION MODEL OF SAND MICROSTRUCTURE
DescriptionThe deformation model of sand soil that takes into account the formation of clusters of particles, and method of measuring its characteristics is suggested. The physical basis of the method is the effect of the stepwise increasing of the sand probe at the odometer pressure by the constant rate of loading and the continuous measuring of deformation. The analysis of settlement and its rate has been allowed to determine the microstructural characteristics of the two-order deformation model of sand. According to the proposed model, with compression of the probe in odometer compaction of the sand takes place due to local strains on the sliding surfaces. The sliding surfaces allocate clusters of sand, and the separated layers of clusters are registered by device in the form of steps of deformation. Layer formation of clusters is initiated by the rigid stamps through the largest mineral grains. Cluster layers create the asymmetric microstructure of the sand probe, its compaction is non uniform but also anisotropic. At the initial interval value of the pressure, the formation of primary clusters occurs, and once they cover the entire probe volume, the compaction of the sand is by crushing them on the secondary smaller cluster sizes. The change of mechanism of the compaction is manifested in the sharp decrease of the settlement rate. The compaction process continues while a larger increment of pressure at each step. The deformation model allows compute the pressure value at which the compaction of the sand reaches the theoretical limit

MODULATED STATOR WINDINGS OF THE MOTOR FOR FAN DRIVES
DescriptionIn poultry industry, animal breeding, greenhouses and vegetable stores a significant amount of fans with asynchronous motors is used to create a microclimate. The fan speed of the fan should be regulated in order to improve the efficiency, so the multispeed motors are used for the fan drives. Line produced two-speed motors with a proportion of the poles number 1:2 have a polar-switched Dahlander stator winding. Two-speed motors with a proportion of the poles number 3:2 and 4:3 have only one stator winding which is poleswitched by the method of amplitude phase shift keying. A drawback of the windings is that they have different energy indicators at different spin rates. In order to create rational diagrams with switching according to the number of poles, which is multiple of three, it is proposed to implement a polyphase MMF modulation of the three-phase winding. As a result of the study, there were procured the stator windings at 4 and 6 poles, which enabled to change the spin speed of the motor in the fan drives without breaking the drive power circuit by the scheme Δ / ΥΥ
