The article discusses the experimental task, the analysis of which cannot be carried out without the use of methods of calculus mathematics. It is shown that the use of modern information technology in educational research tasks to confront theory with real physical experiments lets us raise the level of quality of training future teachers of physics and computer science
We consider the purpose and structure of a software system to monitor the markets and interregional relations of the Rostov region. An example of the interface of a software system is given
The article found that the accuracy of the evaluation of the competitiveness of existing graphical methods largely depends on the skill of the expert and is a subjective process. In addition, only one of the graphic methods followed in graph form the polygon. However, the polygon is not analyzing assessment, as its area does not represent the level of competitiveness of enterprise structure due to association of increase and decrease parameters. In addition, none of the graphical methods are able to predict the level of competitiveness in the long term. The author has developed an information-modeling system for assessment and prediction competitiveness by Pechnikov, which will increase the competitiveness of business structures

Plant growing successes influence the effectiveness not only the branch in itself, but the other branches of agriculture, economics of agricultural enterprises in whole as well. In article the method of calculation of sufficient balance soil is considered.
A computer program, as an information system, is designed to fill in the daily form that simulates the form of SP 20. This document indicates the number of livestock, the feed consumption limit by species and sex and age groups per head and the total limit for a month for all livestock. The computer program is created on the basis of an Excel spreadsheet, which is easily mastered by the user (accountant, accountant, manager). The computer program is developed using the VBA language, which allows you to automate all computing operations for data processing. The user enters only known initial data (cattle groups, species and number of feeds)
Nowadays on the market, there is a large variety of CAD systems and specialized software; however, to solve effectively research and design problems there remains task of development and implementation of national Russian-language information systems that are compatible with the requirements of Russian regulations to support the design and research of industrial buildings and facilities parameters. Being irrespective of the sizes and structure of the industrial enterprises, there are a number of approved design techniques, including calculations of lighting, heating, ventilation, water supply and so on. To improve the efficiency of the interested experts work on their basis there were developed efficient algorithms as well as information systems and database. In the article there is justified the necessity of the developing information systems and processes of industrial premises designing on the example of lighting calculation. We have highlighted the main ways of increasing project work efficiency of engineering and technical personnel on industrial enterprises. For their practical implementation, there is required proper organization of information flows by creating programs and databases complex. The article includes information about the "Calculation of lighting industrial enterprises" subsystem that is the part of the "Designing of industrial enterprises" information system. We have presented methodology of work with the software product in the mode of calculation of industrial premises lightning with fluorescent lamps using the method of light flux utilization factor
In the article, we have described the main causes of
the fuel-air mixtures explosion and such affecting
factors as air blast and fragmental fields. Explosions
are performed using various sources of energy. The
scale of the explosions consequences depends on
their detonation power and the environment in which
they occur. The range of the affected areas can reach
several kilometers. The basic parameter that
characterizes the explosives is the maximum
pressure. Increasing distance from the explosion, the
maximum pressure and pulse decrease and action
duration increases. There is presented method, which
is developed in Windows-based applications that
allows investigate the dependence of the destruction level on the distance and the explosion epicenter.
Algorithm of application operation implements
automatically filling of the "molar mass of
combustible material, g/mol" field depending on the
user’s choice of the flammable substance name. After
calculating the raw data, the user moves to the
calculation of all the parameters and sees the results
of the calculation. By default, the calculation results
are presented in tabular form. Further, the results of
calculation are presented with a graphical
representation of data. The developed software can
be used in the educational process at studying such
disciplines as "Theory of burning and explosion",
"The production safety", "Protection in emergency
situations", and also be recommended to practical
workers in the sphere of labor safety, prediction and
assessment of the technological accidents and
catastrophes consequences, teachers of this profile
disciplines
To solve the problem of reducing the power supply system’s reliability a prompt full-scale diagnostics based on modern methods can help. Inculcation of information systems for the operational diagnostics implementation allows providing the operating personnel with information that enables to predict possible infringements in power transformers work and to prepare in advance an action plan to address them. The paper presents fragments of the developed monitoring system of power transformer using programmable logic controllers. Within the work of the system there were marked such groups of controlled parameters as information about temperature and the cooling system work; magnitude of windings voltage per phase; the windings current values per phase; information about being transmitted and transmitted power; information about the insulation state. There is designed a functional scheme of the system for monitoring the state of the power transformer. There is described a general algorithm of system functioning. There is developed graphical operator interface that allows to monitor the object state and to manage the system state. Using XML markup language there was designed format of data packets. Designed hardware and software package can be used in the educational process, as it allows to improve the quality of students training, to bring them closer to the realities of modern professional activities; in operational activities as complying with the approved domestic calculating methods replacement of foreign software; in science in solving problems of analysis and optimization of operating parameters of power transformers
The basic items of modeling of intellectual techniques improvement are presented in the article. These are done in a form of processes described by mnemonic schemes based on consideration both of “market players” preferences and of programming methods of their fillings-up in accordance with the level of a user’s engineering-managing competence which is required
