The article shows the importance of math description
and grounding the function taking into account the
process of changing the parameter when developing
the methodology of automobile diagnosing. It is
pointed out that after all the prediction error and effort
depend on the choice of approximating function.
The wrong choice of the function can bring to naught
all the efforts to manage safety margin and other parameters
of cars elements. One can find the requirements
to math description and grounding the function
of the parameter change. Based on the analysis of
factors influencing the process of parameters change
and requirements to math description of this process
we have noticed that it is necessary to approximate
the change (increase) of the state variable by the
chance ordered function with increasing realizations.
One can consider the parameter change realization
both strictly and not as a monotone function ranging
from zero to the limit change of the parameter. We
have mentioned that the fore-quoted reasoning with
the account of two groups of factors make possible to
investigate the parameter change at this or that moment
of work as a sum of two random values. We
have made a conclusion that they usually express the
link between the change rate (for instance, detail
wear rate) and the readings of the material properties
and functioning conditions (metal skin hardness, unit
loading on the detail surface, its relative rate of
movement) by the functional determined dependence
got as a result of lab tests or theoretical study. In the
conclusion, one can see that the analysis of the results
of math description of the process of the parameter
change is sufficient enough
The main point of the complementary method of the analysis of motor transport functioning under transition to outsourcing technology consist in elaboratoin of complex of models including the model of driver’s work analysis. This work is dedicated to complex decision of this actual problem
Education was always an important part of the
development of the individual and society, because
education is the process of the formation of mind and
character. Each level of education currently requires
increased attention, since the quality of life of future
graduates directly depends on the quality of the
provision of educational services. Despite the fact that
most of the educational process is formalized by
educational standards, regulatory documents and local
acts of educational institutions, this area continues to
need both automation and the development of various
models, methods and techniques, the use of which will
greatly optimize the implementation of the educational
process. There are few software products, models and
methods that assess the quality of education and the
educational process in general, aimed at individual
elements of the educational system. In all the existing,
basically, there is only support for working with
bachelors, slightly less often with masters and very
rarely with graduate students. This article describes
methodological approaches to assessing the
achievements of graduate students, as well as an
information system for supporting the educational
process of graduate school
The researchers obtained data on the morphological, biochemical and trace element composition of the blood of bull-calves of Hereford breed of different sizes. In this regard, scientists and business executives have three natural questions: 1) whether it is possible to predict the size and thus the meat productivity of bulls using these blood indicators; what are the strength and direction of the influence of certain values of blood indicators on the size and weight of bulls; what blood indicators are similar in meaning, and what are different and how much (to what extent). The article is devoted to the reasoned answers to these questions by applying modern methods of mathematical and numerical modeling to solve the corresponding problems. The results of the study can be used by anyone, due to the fact that Eidos the universal automated system, which is a tool of ask-analysis, is in full open free access on the author's website at: http://lc.kubagro.ru/aidos/_Aidos-X.htm, and numerical examples of solving the mentioned problems with the use of artificial intelligence technologies are placed as a cloud Eidos-application #133
The article considers discrete automatic machines with memory, designed for searching the values of parameters of the system optimizing a merit figure of the system, described by some criterion function. The problem of multiple parameter optimization is shown as a problem of discrete optimization by means of representation of values of parameters of the optimized system in the form of a set of discrete values with a specified step of digitization

Description of hydro kinematic scheme of forest manipulator with additional damper connection is given in the article. Optimal damper parameters for manipulator dynamic loading decrease are defined on the basis of operation mathematical model solution
Conditions in which the work of acoustic magnetic device
proceeds are complicated because of the number of
interconnections. Solving problems under such conditions
analytically is difficult because of many variables
and complexity of some dependencies. The article describes
the conditions in which the work of acoustic
magnetic device, designed for nonchemical treatment of
hydroponic solution, takes place. The criteria, establishing
the initial state of the chains, containing mutual inductance,
are analyzed. The work establishes the criteria
relating the physical parameters of the environment with
the output parameters of the device. The similarity of
conditions of heat transfer on the surface of the device is
provided, and the relation of the scale of temperature
and power lost when heating the ferrite and winding
machine is determined. The criterion of the heat transfer
process is defined. The criterion, determining the relation
of the environment temperature to the thermal
mode of the acoustic magnetic device, is defined. The
criterion of the conditions at the boundaries of the
system and cavitating liquid is determined. It is found,
that the cavitation area appears in the technological volume
of liquid at the work of acoustic magnetic device.
The criterial equation for geometric parameters of different
types and constructions of the acoustic magnetic device is defined. In accordance with the task based on
the third theorem of similarity, the group of criteria that
provides the similarity of the model to the proposed
original by all existing indicators, is selected
