The article discusses different types of drive axles of
all-wheel drive machine. It is shown that if blocked
drive of driving axle easy, it is able to provide the best
traction drive qualities of the all-wheel car, if compensation
of kinematic mismatch in movement of front
and rear wheels. The article provides analysis of the
causes of kinematic mismatch and its consequences.
The analysis was given for the existing methods to
reduce negative influence of kinematic discrepancy on
the work of the four-wheel drive wheeled machine in
locked mode. The method of reduction of kinematic
mismatch by regulations of the air pressure in the tires
of the wheels with one-time control of the leading
moments on the axes was suggested. We show the
relationship between the difference of kinematic radii
of the wheels of different axles and the difference of
the moments leading to them. The algorithm and description
for the system of automatic control of air
pressure in the tire, which realizes the proposed method,
were presented. We have described experimental
methods of determining the energy losses evaluation
from kinematic mismatch when moving all-wheel
drive machine. The article presents the results of the
this assessment in relation to the agricultural wheel
tractor of class 5 moving at different substructures
Among fungus diseases of rice, blast is the most harm-ful. The disease is caused by Pyricularia oryzae Cav. Rice is sensitive to blast at all fazes of vegetation. In Russia, the purposeful breeding of rice varieties re-sistant to this disease began in 1982. Over the past period, the rice varieties which are genetically protect-ed from blast and not requiring crop protection have been created
The reliability of work of the technical systems significantly influences the technological losses of manufacture process. During the counting the availability ratio of the technical system it is recommended to take into the consideration implicit as well as evident breakdowns of all separate components of the whole object. There is a formula for counting technological losses depending on the availability ratio of technical object. Similar formulas for counting losses proceeding of atmosphere and water resources pollution, pollution of soils with hard matters are obtained. Introduced identities bring together reliability of the technical systems and separate components of ecological losses
In the conditions of foothill soil-climatic zones of the Republic of Dagestan we have explored the creation of low-cost intensive apple orchards. This work was initiated by the authors in 2011 due to the Republic "Horticulture Development Program for 2011-2016", according to which, it was planned to plant 6,200 hectares of new gardens. However, the experience of gardening in the Republic, taking into account recently prevailing socio-economic relations, subsidized nature of the economic and a chronic lack of funds, shows the riskiness of the creation of high-tech pillar-dwarf plants with the cost of 1-1,5 million rubles per hectare. Inability to overcome quickly the existing problems in the development of the industry sharp gardening at this stage, forced us to seek a way in a single direction - reducing the cost of the creation of apple orchards, while maintaining their high economic efficiency. Theoretical studies were realized as a planting of the apple garden in the district of Karabudakhkent of Dagestan of four perspective late-ripening varieties on the medium growing rootstock in the spring of 2013. The results of the three years of scientific research were embodied in the creation of intensive apple garden on the medium growing rootstock which allow now to make the following preliminary conclusions: 1.It is possible here in Dagestan to create intensive apple orchards, with an estimated yield of 30-40 tons per hectare, on the medium growing rootstock already at a density of 666 trees per hectare. 2. Cost of such a garden, without compromising quality indicators, can be reduced in the current market price of labor and the necessary materials, up to 214 thousand rubles per hectare, with access to the full return of all costs in the seventh year of operation. Such intensive garden, according to common practice, during the period of operation is able to give at least 22 full-weighty harvests and provide a net profit about 6.6 million rubles per hectare, or 236,000 rubles per hectare per year for the entire period of alienation of the land for a garden
The article presents a theoretical substantiation, methods of numerical calculations and software implementation of the decision of problems of statistics, in particular the study of statistical distributions, methods of information theory. On the basis of empirical data by calculation we have determined the number of observations used for the analysis of statistical distributions. The proposed method of calculating the amount of information is not based on assumptions about the independence of observations and the normal distribution, i.e., is non-parametric and ensures the correct modeling of nonlinear systems, and also allows comparable to process heterogeneous (measured in scales of different types) data numeric and non-numeric nature that are measured in different units. Thus, ASC-analysis and "Eidos" system is a modern innovation (ready for implementation) technology solving problems of statistical methods of information theory. This article can be used as a description of the laboratory work in the disciplines of: intelligent systems; knowledge engineering and intelligent systems; intelligent technologies and knowledge representation; knowledge representation in intelligent systems; foundations of intelligent systems; introduction to neuromaturation and methods neural networks; fundamentals of artificial intelligence; intelligent technologies in science and education; knowledge management; automated system-cognitive analysis and "Eidos" intelligent system which the author is developing currently, but also in other disciplines associated with the transformation of data into information, and its transformation into knowledge and application of this knowledge to solve problems of identification, forecasting, decision making and research of the simulated subject area (which is virtually all subjects in all fields of science)
In the article we present generalized block diagrams of stationary and transport systems of uninterrupted electrosupply, as well as their maintenance and the basic operating modes providing uninterrupted electrosupply of crucial consumers. Classification of systems of uninterrupted electrosupply is resulted. The basic classification attributes of systems of uninterrupted electrosupply are their assignment for stationary or transport consumers of the electric power, types of used basic, reserve and emergency sources and converters of the electric power. Besides systems of uninterrupted electrosupply can be classified under circuits of connection to consumers of the electric power, their division on a sort of a current (constant, variable, high-frequency), breaks in electrosupply, to type of the switching equipment and so on. For the estimation of the efficiency of systems of uninterrupted electrosupply it is offered to use the following criteria of efficiency: Power and weight-dimension parameters, parameters of reliability, quality of the electric power and cost. Analytical expressions for calculation of parameters of the estimation of efficiency of systems of uninterrupted electrosupply are resulted. The classification of systems of uninterrupted electrosupply suggested in article and modes of their work, and also the basic criteria of an estimation of efficiency will allow raising efficiency of pre-design works on creation of systems with improved customer characteristics with use of modern element base
We have investigated the influence of nickel oxide in
