METHODS OF DIAGNOSIS STUDY FOR NUMBER OF STATIONS FOR INTERACTIVE MONITORING THE TECHNICAL CONDITION OF MACHINERY IN AGRICULTURE

abstract 1281704011 issue 128 pp. 188 – 199 28.04.2017 ru 347
Condition monitoring is a necessary element of the transport and special machinery in agriculture. The task of the control operations other than the determination of the technical state of the object is to determine the required amount of work, as well as rational amount of collateral the repair of which could be combined with the next maintenance. Based on the results of processing of the information, we may generate requests for service. In the conditions of uncertainty of receipt of requests for servicing of individual machines, estimated volumes and timing, we have am appropriate development of applied technique of justification of the number of diagnostic posts for interactive control of a technical condition of vehicles and special machinery in agriculture. The presented methodology is based on probabilistic methods, and allows the quick optimization of the number of existing posts interactive diagnostics in the enterprise, if necessary, translating the existing posts in "standby" mode, or Vice versa, returning from a reserve in "work" mode. The production and technical base of the enterprise service based on the specific assumptions are considered as a system of mass service (SMO), and the function of such a SMO – as the process of mass service. The process of queuing as applied to interactive diagnosis are "Markov" processes "death and reproduction" with a finite or countable number of States and continuous time. To describe the states of the system we use the system of the Kolmogorov equations for steady state of "Markov" process. On their basis, we have determined average queue length, time of stay orders in the queue, number of busy channels and the bandwidth of the CFR. Using the intensity of the requests and the service time of a single application for specific equipment, the article establishes the efficiency of online diagnosis posts. The result of the proposed applied methodology enables timely decision-making about the need for reconstruction or technical re-equipment of the company

METHODS OF DETERMINATION OF CROTONALDEHYDE IN FOOD

abstract 0941310041 issue 94 pp. 622 – 631 27.12.2013 ru 1379
The article presents a review of the existing methods for the determination of crotonaldehyde in food. The necessity of this component in the control of food products, including wine, is visible because of its toxicity and the probability of formation during microbial synthesis and chemical transformations. The article describes the developed qualitative method of determining the content of crotonaldehyde in table wines with spectrophotometry

METHODS OF DESTROYING COMMON RAGWEED IN SUNFLOWER CROPS IN THE KRASNODAR REGION

abstract 1211607069 issue 121 pp. 1110 – 1120 30.09.2016 ru 669
Ragweed plant became quarantine malware on the territory of Southern Russia. In the Krasnodar region it has been extended to the territory of more than 4.62 million hectares. In the areas of its growth, it causes great damage to agriculture. By developing a strong root system and aboveground, it inhibits the row crops, especially sunflower. Another problem with this weed is producing large amounts of pollen that causes allergic reactions in the majority of residents of the province. This article discusses the importance of using modern methods of ragweed oppression, including chemical and biological methods in sunflower crops

METHODS OF DEFINITION OF COMPLEX MACHINE GRAINS’ AND SEEDS’ TRAUMATIZING

abstract 1201606026 issue 120 pp. 399 – 411 30.06.2016 ru 467
Damage of grain and seeds by machines makes essential negative impact on sowing qualities of seeds and processing properties of grain. While processing of grain a lot of various cars and actions differently injure weevils. To exclude traumatizing of grains in the course of mechanical preparation is not obviously possible, as working bodies of cars are a source of mechanical and thermomechanical damages. Besides, injured weevils on the physical-mechanical properties practically do not differ from whole, i.e. they do not possess signs for machine division. To reduce traumatizing of weevils is possible with the help of application of optimum technologies of machining, selection of the conforming technological modes, using as a part of actions of constructional stuffs with a low elastic modulus, perfection of their design data. For definition of injuring ability of various machines and actions through which takes place grain lots, have developed a procedure which allows with high degree of reliance to estimate complex traumatizing of weevils (namely, their outside integuments and intrinsic frames) machines and the actions which are a part of aggregates and complexes for machine preparation of grain and seeds. The developed procedure bases on a basis of the standard documents regulating test methods of agricultural machinery and together with it allows to consider connatural heterogeneity of the grain lots arriving for processing

METHODS OF CONSTRUCTING EFFICIENT ALGORITHMS BYPASSING BLOCKING ACCESS TO WEB-RESOURCES BASED ON HTTP TUNNELS

abstract 1531909025 issue 153 pp. 240 – 256 29.11.2019 ru 168
At present, the problems of blocking network traffic in computer networks, in particular, in the global Internet, are becoming increasingly topical. Understanding blocking mechanisms, opening new opportunities to circumvent such protection will give us, on the one hand, both new methods and methods of protection against unwanted blockages, and the vector of development of funds, in fact, stopping unwanted traffic, obstacles passing through network nodes. The article proposes an approach to effectively bypass access restrictions to websites based on HTTP tunneling with minimal costs, combined with the approach used in peer-to-peer networks. A description of the algorithm and its key features. A new approach has been introduced in the task of ensuring the accessibility of websites, which has several advantages and eliminates the disadvantages of existing solutions in the form of anonymous networks - the use of special node solutions and a strong dependence on the number of nodes in the anonymous network. The level of development of modern network infrastructure, the transition of society and most of human civilization to the information-network existence dictates new requirements for technical means of monitoring and analyzing network traffic. That, in turn, requires the development of new approaches to solving relevant problems

METHODS OF CHOOSING DIAGNOSED VEHICLE PARAMETERS IN AGRICULTURE

abstract 1171603052 issue 117 pp. 796 – 809 31.03.2016 ru 291
The article presents an analysis of the existing approach to automobiles technical maintenance in agriculture. We have pointed out that in modern conditions it is impossible to forecast the automobiles maintenance operation frequency and as a result its improvement as well. It is obvious that one cannot achieve the considerable increase of maintenance operation efficiency by separate means and there exist the necessity to treat it as a system and use the up-to-date methods to investigate and improve complicated systems. We have made a conclusion that the increase of maintenance operation efficiency is not possible without some rational strategy of maintenance operation and repair. We have shown that the program of maintenance operation and repair being an integral part of automobiles technical maintenance has considerable effect on maintenance and repair quality. As a result, there is some necessity of the developed system of parameters diagnosing and control in technical maintenance and repair. We have shown that to get sufficient diagnose information one needs selection of the controlled parameters which give maximum information about the object technical status taking into account possible characteristics of its operational faults. We have discovered that in order to solve the task it is necessary to have the object’s information pattern, calculation of possible characteristics of the controlled object being in good or bad order due to some parts fault, evaluation of information brought by every parameter and determining parameters to be diagnosed. We have proposed to evaluate the parameters’ information value with the help of information entropy as uncertainty measure that is one of the main concepts of the information theory. Because of solving the task, we have got the aggregate of the controlled automobile parameters orderable according to the amount of information
