The global financial crisis has had a negative impact on the domestic economy, resulting in a much more complicated task of achieving the most important indicators specified in the Concept of long-term socio-economic development of the Russian Federation until 2020. Implementation of the goals depends on a number of factors, including, how successful energy efficiency policy in Russia will be implemented.
In this regard, actual task is to analyze the impact of the energy factor on the dynamics of change of gross domestic product in Russia
The scheme of the energetic balance of the autonomous energy supply system of mobile technological lines that produces dry fire wood chips on the basis of the engine installation with the Stirling engine, using a part producible biogenic fuel, is produced; the mathematical model of the functioning of the present energy supply system of mobile technological line is elaborated
It is necessary to know exact value of the full
dispersion of waveguides, which leads to broadening
and reduction of pulse amplitude for modeling laser
radiation passage in quantum cryptography systems.
The operation purpose was obtaining of dependences
on a wavelength of various dispersion types according
to the Sellmeier’ sequationand optical pulse radiation
modelling in quantum communication systems.
Dependences of the material, waveguide and
chromatic dispersions on length of a wave according to
the Sellmeier’s equation which allows to consider an
optical fiber’s material are received. Distribution of a
cryptographic impulse through fiber-optical
communication lines of various extent is simulated
In the article we have represented the following items: heating model of discharge device of the ozone gen-erator which allows to examine the transient process and establishes dependence of heating time constant of the dielectric barriers on constructive parameters of discharge device. The rational parameters of design of the ozone generator for in-hive treatment of the bee families are defined; recommendations for utilization of the results of investigations are given
Mathematical modeling is one of the leading places among methods of research of economic systems and processes. The article considers the main management problem of the rocket-space complex in modern conditions and gives a brief description of this problem in conjunction with the tasks of innovative modernization and financial sustainability of enterprises of the complex. We have considered a common situation where the enterprises of the rocket-space complex in implementation of its development is carrying out an investment project, the financing of which is taken from a loan. It is proved that the implementation of this project can be appropriate, if as a result of the implementation the net present value of the enterprise increases. We have developed a model, which provides optimization of financial providing of high-tech enterprises of the rocket-space complex in the implementation of their modernization project taking into account the specifics of the use of own and borrowed funds
The article describes the methodology and the approaches to the modeling of the growth of artificial energy forests. The features of the growth modeling of the artificial energy forests are shown
The work was carried out not only in the scientific, but
also in practical directions, the key part of which was
the modeling of the system. Consideration of the
presented modeling processes occurred on the basis of
the delivered pedagogical experiment associated with
the introduction in the discipline "Engineering
Graphics" of a new tool for the military educational
institution to obtain the final graphic design document.
The purpose of the experiment included a comparative
analysis of modeling tools (manual and machine) and
their impact on the production of the final product
(drawing). As a tool, the computer-aided design
system Кompas-3D was used. The presented research
was worked out in practical classes of the specified
discipline, the theme of one of them was "Image of
thread and threaded connections". With the help of the
graphic editor Compass-3D, a model of the shaft and
bushing with the specified thread profile was obtained,
as well as the assembly unit based on them. The entire
way of obtaining the above objects for convenience
and ease of perception has been broken down into
certain stages. The results of the pedagogical
experiment were very satisfactory; the goal of the
practical training was fully achieved
In the modern conditions of dynamic development of the market system, the economy, feeling polynomial enthusiasm and recessions, demands external influence, regulation, management. It isn't possible to realize an effective control system of economy without understanding of a consequence. The regulating structure represented by the state needs an effective system of the support of decision-making allowing to estimate the consequences of the made decisions before their direct realization. Use of modern methods of complex estimation for modeling of market system on the basis of trees of criteria and matrixes of convolution allows forming a static market model in the form of the functions of sensitivity interpreted as curves of supply and demand. However, the questions of creation of dynamic market system on the basis of these mechanisms weren't discussed so far. In this article the questions of possibility of modeling of dynamics of the market system built on the basis of mechanisms of complex estimation are discussed. Relevance of the chosen method depends on the possibility of preliminary formation of possible outcomes of an event in the form of the count on definition further of probability of transition to each of states on the basis of a complex assessment of the individual of "advantage" of such transition. An additional benefit of such approach is that fact that when forming market system from some contingent of participants with different behavior models for each of them there is an opportunity to create the scenario, and when receiving at a stage of modeling of result to reconsider the new created structure of structure of society
The article presents the approach to modeling of microprofile felling areas as the bearing surface of harvesting machines and is an example of the model obtained in the study of the behavior of wheeled vehicle on uneven support surface
