The article analyzes intellectual methods of image comparison. We give a brief description of existing methods: metric, topological and stochastic designed to solve this problem, indicating their advantages and disadvantages. This method is based on comparing of images by means of separation of the given domain into segments and calculation of pixels having certain optical density. The illustration example is presented. A computer program was created to use this method. The value of the segment is given by the operator with following limits: more than 3 single pixels and less than half of chosen square of image. The program makes up a segmental matrix of the image, which is compared in some interval of time to the current matrix. This method is used for interval monitoring of objects from the same point of observation

In Russia, as well as in foreign practice, classic yogurts are more required. Depending on the value of imported dry starters, the proposed technology allowing reduction in their quantities in yogurt technology is very crucial. It will affect the cost of the finished products. In yogurt technology, the possibility of using physical techniques, with the purpose of intensifying the process of producing yogurt, is very little reflected. Pre-activation of the leaven by electromagnetic field – lower frequency before fermenting in the production of yogurt is one of the technological tricks that speed up the fermenting process and reduce the quantity of starters. The advantage of the proposed technology is its ease of implementation, not requiring additional cost of electricity and also enhanced maximum reduction of additional chemicals which are used as raw materials to create a special environment for the growth of microorganisms belonging to the leaven. In this work, the overview of the existing principles for accelerating the fermentation process of milk is given. In this work, the research results of accelerating technology of fermenting milk for yogurt are presented. Mathematical process of experimental data enables the optimization, fermentation process using leaven FD-DVS YF-L812 10Yo-Flex. The optimal temperature and duration for the maximum acceleration of the process of obtaining yogurt at a given frequency of electromagnetic field are identified. We have given organoleptic characteristics of yoghurt prepared using the activated ferment
Тhe article presents an investigation of hydrodynamic mixer for biodiesel production from vegetable oils hyperacidity in the conditions of agricultural companies. The process of hydrodynamic mixer which mixes the flow of biofuels from jatropha oil with carbon dioxide to wash it. The regularities of disclosing the relationship of the parameters (diameter and length of the mixing chamber), the mode (the pressure and flow rate) from the medium (dynamic viscosity, density, elasticity) to the energy characteristics of the process (mixing power on). Based on the method of similarity and dimensions of physical quantities obtained criterion turbulence. A reduction in the flow pressure and agitation power with increasing diameter. We have justified the mode (pressure at the nozzle exit corresponds to the critical), in which the carbon dioxide gets into the mixing chamber properties of liquids, solutions for biofuels, and the mixture becomes a quasi-homogeneous. Based criteria of regime change from a supersonic flow in the subsonic, allowed us to determine the condition of quasi-homogeneity of the mixture. It is proved that we form a supersonic flow liquid-gas at the same time it is transformed into subsonic, accompanied by the acoustic cavitation effect leap remixing due to isentropic pressure jump. The article justifies the physics of cavitation effects of carbon dioxide on biofuels, result of which is to improve the physical and chemical properties of the medium due to the structuring of the molecules of the solution, which has a positive effect on the mixing

Currently, for producers of mineral fertilizers one of the main tasks is the process of creating a supply chain of mineral fertilizers delivery to agricultural consumers, running on a «Just-in-time» way. The effective operation of such a supply chain has to be influenced by many factors, including: the technology of agricultural production, seasonality of agricultural work, the structure of the distribution channel of mineral fertilizers, the geographical features of consumers, the availability of appropriate infrastructure, etc. Critical elements of the infrastructure are warehouses and equipment for storage of mineral fertilizers, as well as the road network. For example, farms in the Rostov region were analyzed for the infrastructure necessary for the successful supply of mineral fertilizer agricultural consumers. It was found that the capacity of warehouses and facilities for the storage of mineral fertilizers and distribution of cultivated areas between agricultural enterprises of different size are diametrically opposed. The process of delivery of mineral fertilizers need to be developed taking into account the shortage or complete lack of storage capacity for their storage, especially for small enterprises. The existing road network, with paved allows us to deliver of mineral fertilizers virtually all consumers by road transport. This dictates the feasibility of delivery of mineral fertilizers to consumers by road transport in soft containers (Big Bags), allowing the storage in the open air
Efficient dairy cattle breeding are largely dependent from technology content and service animals. Most farms use a tethered way content. With this method of milking, the technology requires the introduction of new techniques to increase productivity on the farm and cost reduction of dairy products. The most rational is improving the design of existing milking machines. Regarded device for automatic removal of hanging part of a milking machine, its structure and working principle. The main unit of the device is a pneumatic motor that operates from the vacuum system of the milking plant. In the housing mounted on the shaft of the pneumatic motor rotor with curved vanes, there are magnetic elements. These elements should have the necessary geometrical and force parameters to ensure the normal operation of the device for automatic removal of hanging part of milking machine. The article describes a laboratory research and an analysis of the magnetic elements. In laboratory studies, we have revealed a dependence of the traction capacity of pneumatic motor from linear and power parameters of the magnetic elements, as well as established necessary geometric parameters and the magnetic field strength of the elements for normal operation
For explaining the regulatory mechanisms of biological the methods of classical biology, chemistry and physics are clearly inadequate, since the structure and function of these mechanisms are determined by the motion of the electron clouds in conjugated molecules. This "movement" can lead eventually to a complex organization called life only if they are subject to certain static laws and, therefore, may eventually be known in all the complexity of their relationships. Biological objects, resulting in the evolution of the environment, are like a part of that environment. Information stored in the seed, based in its deployment on energy and material resources of the environment. Moreover, in the process of development body derives more information from the environment. Nature has the extreme complexity and diversity. Examples include a huge variety of organisms, the complexity of atomic processes, the structure of the solar system and the stellar galaxies. There are four types of different interactions with the help of which we describe all physical phenomena. Today, it seems to us that all the various manifestations of the nature of elementary particles are reduced to the action between them of these four kinds of forces. The most famous of these are the gravitational Zion and electromagnetic forces, which are directly manifested in the world around us. Gravity allows us to stay on the Earth and allows planets to stay in their orbits. Electromagnetic interactions of electrons inside atoms and molecules cause all known chemical and physical properties of ordinary solids, liquids and gases and, in addition, are the basis of all of the processes occurring in living organisms. Research in the field of magneto proved that the biological systems are selectively susceptible to the action of electromagnetic fields as a function of their intensity, exposure time and frequency
