The article presents native and foreign bench-top
and board methods to test the automobile break
systems. One can find information about some
native trailer-break stands. We have analyzed their
advantages and drawbacks such as low information
capacity, high diagnostics processing time, low
quality of regulation and maintenance operations
due to big influence of the operator’s experience,
his knowledge and individual characteristics, and
great instability of manual test modes on the results
of the investigations. To remove these shortcomings
they have had some experiments at MADI in order
to develop the module to the brake qualities stand.
When using it one can have automatic diagnoses
and flow chart is presented in the article. Due to the
existing vehicles’ state inspection mode and
diagnostic means in our country there appeared new
stands for brakes control. One can attribute to these
devices a range of brake qualities stands developed
and produced at Novgorod plant GARO. These are
STS-3, STS-10 and STO series stands for cars,
trucks, buses and micro-buses. The article also
presents some foreign stands used in Russia such as
universal brake stands STM by META firm, the
break stand IW7 Eurosystem by MAHARUSSIA
firm. We have presented in the article the results of
the analysis of simple and complicated board means
of diagnosis as “Eftor-2”, “Effect”
The article presents the analysis of climatic data concerning Michurinsk district of Tambov region, which is necessary for modeling of stressors, on the stage of their maximum values, which will help to increase the precision of selection procedure in fruit crop forms. On the base of the investigation, differences in initial fruit crop forms by their adaptivity and productivity under stressor effect on the level of their maximum values were revealed
Based on the analysis of domestic and foreign scientific and patent literature, possible options to reduce weight of electro technical steel in magnetic circuits of electrical machines are explored. A search for the best options for the manufacture of magnetic induction motors stators technology aimed at improving the utilization of electrical steel and improving the energy performance of electric machines is carried out. All the variants are described and illustrated in detail in the drawings. It is pointed out the advantages and disadvantages of each method of manufacturing magnetic wires and the reasons why certain suggestions of technology of manufacturing magnetic circuits have not been implemented in mass production. The main indicators characterizing the manufacturability of constructive decisions are recommended. Economic indicators have been put in the basis of the choice of the optimal variant while designing the electrical machine. An optimal variant should be considered the variant in which all the technical requirements at lowest total cost are met. The latter should be understood not only the cost of materials and machine manufacturers, but also the cost of operation. The dependence of the energy performance of motors with modular designs of stators from the manufacturing technology is pointed out. The existing technology of the most mass electric motors series production, the following disadvantages are typical: low coefficient of utilization of electro technical steel; high specific material capacity, the cost of technology and labor intensity of production; low labour productivity and level of automation of technological process. Due to the fact that the possibilities of increasing of the machines’ specific weight characteristics due to the usage of new magnetic and dielectric materials are exhausted, it is advisable to change the technology of electric motors production, moving away from the traditional design
In this work, the authors presented the results of monitoring urolithiasis in cats in Krasnodar in the period from 2016-2017. The authors established the sexual, age and breed predisposition of animals to this pathology; the seasonality of the disease was studied. An analysis of the actual data and reports of various authors made it possible to conclude that urolithiasis in cats is a polyethological disease. As a result of carried out hematological studies, the presence of an inflammatory process, which was manifested by lymphocytopenia, an insignificant increase in neutrophils and monocytes, as well as hematocrit, was ascertained. A laboratory analysis of urine showed that urine, as a rule, is turbid with an admixture of blood and sand, precipitating rapidly. The authors found an increase in the volume of urine in sick animals due to the inability to remove it, the specific gravity fluctuated within the limits of 1.015-1.020; pH = 7.5-8. With microscopy of the urine sediment, both unorganized and organized sediments were detected. The ultrasound examination of the bladder showed the presence in its cavity echo-positive particles in a suspended state, as well as sections of the desquamated mucosa
The analysis of information security tools and systems is carried out in this article. This analysis revealed that the functioning of many of them associated with the implementation of intensive logical calculations. Ways of representing Boolean functions are analyzed, the criteria of efficiency and ways to increase productivity tools and security systems are presented
The system of indicators characterizing the financial
condition of a commercial organization, the major
thing is profitability of its operations as the ratio of
profit on sales and revenues, the ratio of profit before
tax and the average annual value of total assets, the
ratio of net profit and the average value of all assets,
net income and average equity. Great practical
importance for the efficient management of resources
economic entity is marginal analysis, but it requires, in
our opinion, improvement. In the academic literature
on management analysis it is recommended to
determine the relative value of the stock of financial
strength ratio of the absolute value of the stock of
financial strength and actual revenue; financial
headroom suggested determined by the difference
between the actual value of revenue and earnings, the
corresponding break-even point. The relative value of
the stock of financial strength should be determined, in
our opinion, the ratio of the absolute value of the stock
of financial strength and the amount of revenue in the
break-even point. Recommended in textbooks relative
value of the stock of financial strength is a share of
stock of financial strength in the actual revenue. The
method of rating the financial condition of commercial
organizations (credit scoring of the American
economist D. Durant) return on total assets is also a
priority index, largely determining the solvency and
liquidity of the balance sheet, the financial stability of
the business entity. However, in practice the
profitability of the invested capital is not always
characterized by an optimal investment
The article gives the analysis of installations using physical factors for seeds presowing treatment, particularly an electromagnetic field. The author has also cited an example of the registered installations for seeds presowing treatment by means of an electromagnetic field
The article presents an analysis of an innovative activity of four Russian metallurgical enterprises: "Ruspolimet", JSC "Ural Smithy", JSC "Stupino Metallurgical Company", JSC "VSMPO" via mathematical modeling using Monte Carlo method. The results of the assessment of innovative activity of Russian metallurgical companies were identified in five years dynamics. An assessment of the current innovative activity was made by the calculation of an integral index of the innovative activity. The calculation was based on such six indicators as the proportion of staff employed in R & D; the level of development of new technology; the degree of development of new products; share of material resources for R & D; degree of security of enterprise intellectual property; the share of investment in innovative projects and it was analyzed from 2007 to 2011. On the basis of this data the integral indicator of the innovative activity of metallurgical companies was calculated by well-known method of weighting coefficients. The comparative analysis of integral indicators of the innovative activity of considered companies made it possible to range their level of the innovative activity and to characterize the current state of their business. Based on Monte Carlo method a variation interval of the integral indicator was obtained and detailed instructions to choose the strategy of the innovative development of metallurgical enterprises were given as well
