01.00.00 Physical-mathematical sciences
Description
The relationship of Mathematical Statistics (wider - Mathematical methods of research) and history is multifaceted. In our opinion, the history of mathematical statistics is an integral part of this mathematical discipline. We have given a review of our works on the history of statistical methods. The role of mathematical statistics for the history is very important. In this article, we restrict ourselves to the questions of chronology. For centuries, the chronology is considered as a part of applied mathematics. The main problem is that the whole "common" concept of the Russian and the World history as a whole presented in textbooks was faked by the opponents of Russia after the collapse of the global Empire (Russian kingdom) in the early 17th century - 400 years ago. The stories about historical events are the information weapon. It was used by the new rulers to suppress the resistance of the vanquished. A new mathematical and statistical chronology of general and Russian history, which was built by a scientific team led by Academician Fomenko, has been helpful for the discussion about the current economic and political problems of relations between Russia and the West in the XXI century. In our opinion, the new chronology of the World and Russian history should be one of the foundations of state-patriotic ideology and deriving practical solutions. The purpose of this article is to give the initial idea of the new chronology from this point of view

ASPECTS OF THE PREPARATION OF COMMANDERS OF RESCUE EQUIPMENT BOATS IN A MARITIME UNIVERSITY
Description
Every year on the seas, on average, up to 100 accidents occur involving the loss of ships and men. A high proportion of accidents exist for the ships of the Russian Federation. Thus, in 2015, there were 72 emergency cases and 86 sailors died. The reasons for the absolute majority of emergency incidents with ships are unsatisfactory technical condition of the ship; the errors and omissions in the course of organizational and technological activities related to the shipping industry; adverse meteorological situation in the navigation area and its negative impact on the ship; the negative effect of the "human factor". The entry into force of a number of international conventions, codes and resolutions of the International Maritime organization (IMO) and national legislative acts and normative documents related to the safe operation of ships and prevention of pollution of the aquatic environment certainly contributes to the resolution of these problems. However, the widespread reduction in the size of crews increased the load on the navigation composition, and this circumstance sometimes becomes fatal to ship and crew. In case of death of the ship, the sailors can escape with the help of individual and collective rescue means. For this purpose, in accordance with the IMO requirements and curricula, the future command structure of the transport vessels undergoing special training in the Maritime training institutes with the Coastal training centers (BUTTS), and receive appropriate certificates confirming their theoretical and practical training. The article analyzes the conventional process of preparation of the students to act in emergency situations, the ability to apply individual and collective rescue means to manage the duty and lifeboat and life raft, to organize the survival of the people on the rescue means at sea

TO THE NONPARAMETRIC IDENTIFICATION OF TECHNOLOGICAL PROCESS OF SEQUENCE OBJECTS
Description
The task of nonparametric identification of sequence objects with discrete-continuous nature of the process under nonparametric uncertainty, i.e. in conditions where a priori information is not sufficient for an informed choice of a model structure up to parameters is considered. Among series-connected objects, there can be objects both dynamic and instantaneous ones with a lag. This kind of technological chains is common in various industries, particularly in metal, power, oil refining, etc. in solving this problem were used methods of nonparametric identification theory, mathematical statistics and statistical modeling. The theory of nonparametric systems is based on local approximation methods, in particular algorithms for nonparametric estimation of different kind of dependency from observation of input-output variables of the object. The article presents a nonparametric model for the group of spinning objects with delay. In the work we show in detail the results of numerical studies showing that the use of nonparametric algorithms allows predicting process performance with sufficient accuracy

TO THE QUESTION OF MATHEMATICAL METHODS DEVELOPMENT OF CONTROLLING
01.00.00 Physical-mathematical sciences
Description
On the basis of the objective analysis it must be noted that in the arsenal of managers, especially foreign ones, there is practically no fundamentally new methods and tools of controlling. So says the executive director of Russian Association of Controllers prof. S. G. Falco. However, promising mathematical and instrumental methods of controlling actively developed in our country. It is necessary to implement them. For example, managers should be used techniques which discussed in the book by Orlov AI, Lutsenko EV, Loikaw VI "Advanced mathematical and instrumental methods of controlling" (2015). These methods are based on the modern development of mathematics as a whole - on the system interval fuzzy math (see the same named book by Orlov AI and Lutsenko EV, 2014). Considered methods are developed in accordance with the new paradigm of mathematical methods of research. It includes new paradigms of applied statistics, mathematical statistics, mathematical methods of economics, methods of analysis of statistical and expert data in management and control. In the XXI century there were more than 10 books issued, developed in accordance with the new paradigm of mathematical methods of research. The systems approach to solving specific applications often requires going beyond the economy. Very important are the procedures for the introduction of innovative methods and tools. In this article we consider the above research results in their interconnection

Description
The care of the finance is the starting moment and a final result of the activity of any subject of managing. The organization with a reliable financial condition is a part of the locomotive, which accelerates market transformations, improving a national economy. In the article, we showed the analysis of theoretical and conceptual positions of financial stability of the organizations. It is revealed, that their accounting reporting used for an estimation of a financial condition, the beginnings and the terminations of the accounting period are made only for a moment, and creation of the income of the organization and its further distribution completely drop out of a field of vision. The article has a research character, expressed that in it the basic approaches to an estimation of financial stability of the organization on an example of Society with limited liability «Gumilovskoe» are considered and is revealed, that by different techniques the type of financial stability from unstable up to normal is inherent in it. With the purpose of improvement of financial stability of Society with limited liability «Gumilovskoe» optimization of its balance by a correcting of some articles of accounting balance based on recommended values of financial parameters according to the multifactorial model offered by A.V. Grachev is made. Economic feasibility of the given optimization is proved and the complex of actions on increase of financial stability of the organization is offered

ORGANIZATIONAL AND ECONOMIC SUPPORT OF SPACE INDUSTRY
Description
We have a number of studies on the problems of the development of organizational and economic support for control tasks in the aerospace industry, primarily in the field of project management development of rocket and space technology. This article aims at summing up the preliminary results of the research cycle. Since the core funding of space activities in Russia is carried out in accordance with approved government bodies targeted programs from the state budget, among the indicators of financial and economic activities of enterprises should focus not maximize profits, and decrease costs. We must estimate of the feasibility of projects in the field of space activities, primarily on the scientific and technical feasibility and the socio-economic needs, and resource provision. What is important is the analysis of all types of resources - material, production, human resources, time, and not just financial. As a basic organizational and economic theory we suggest the use of solidary information economy, high-tech management, controlling, developed on the basis of a new paradigm of mathematical methods of economics, especially econometrics, decision theory, organizational and economic modeling. In project management to create rocket and space technology should take into account the risks of their implementation. In estimation of the feasibility of such projects there should be an analysis of risk assessment, as well as the use of modern statistical and expert methods of forecasting the dynamics of technical and economic indicators project. As practice shows, we have to develop new organizational-economic and economicmathematical models and methods. It is necessary to build a knowledge base in the art and to adequately fill it with modern knowledge based on scientific data of the Russian index of citing. In connection with the duration of the projects of development of rocket and space technology, we note the need to take account of inflation in the planning and evaluation of the financial and economic activities of enterprises, organizations and industry as a whole

06.00.00 Agricultural sciences
Description
This article is devoted to studying the influence of conditions of keeping and feedings on broilers of Hubbard RedBro cross, and the quality of the received products in case of application of floor and cellular content in the conditions of a farm. It was found that when receiving a feed of its own production with the use of feed ingredients grown in farms without pesticides, recorded a statistically significant reduction in the potentially dangerous health animal substances. As compared with a factory forage therein reduced pesticide content by 14 times, mercury and arsenic is 24 times, 5 times cadmium, lead 10 times. Results of studying of economic indicators of cultivation of broilers of cross Hubbard RedBro and also chemical composition and quality of carcasses demonstrated that the essential difference between a floor and cellular condition of keeping is not established, however use of a diet on the basis of what forages promoted statistically reliable decrease in concentration of toxic metals in muscles of a bird of experienced groups. As a result it was found that use of the researched compound feed in diets of broilers raised indicators of biosafety and provided ecologically safe (“organic”) meat products of poultry farming

Description
Waterflooding helps in the recovery of great amount of oil that would have otherwise been abandoned in the reservoir that is depleted. A reservoir in the Niger Delta, Reservoir X has been used to illustrate this. Reservoir X had oil initially in place as 7.345 MMSTB and was produced for some time with the reservoir natural energy. The remaining oil in the reservoir as at the time that the natural energy of the reservoir was no more sufficient to produce oil was 2.96MMSTB. The reservoir has been left as depleted reservoir with the remaining oil in it. But from the analysis conducted in this work it is seen that if secondary oil recovery project by waterflooding is embarked on the reservoir, part of the remaining abandoned oil would be recovered. With the specifications given, about 1.22MMSTB of the 2.96MMSTB of oil in reservoir X would be produced as at the breakthrough time of 580 days. Moreover, considering the economic aspect of the project, reservoir X and is good to be invested in. From the NPV calculations performed, it is seen that the NPV of reservoir X at discount rate of 10% is $4.13 million

Description
In Nigeria, belt of bituminous sand stretches to the East of Ijebu-Ode (Ogun State) in the district of Siluko and Akotogbo, Okitipupa (Ondo Sate) and Edo State. It covers a distance of approximately 110 km and lies in the upper cretaceous sequence of the Abeokuta formation in the eastern Dahomey Basin. Reserves of bituminous sand in Nigeria is estimated to be around 30- 40 billion barrels with a possibility to extract 3654 × 106 barrels. From the approximately 30-40 billion barrels of oil sand, Ogun State has more than 40% in reserve. However, this huge stock of oil sand in Nigeria is yet to be exploited. This article provides an assessment of technological solutions for the design and development of tar sand fields in Nigeria. Reserves of oil sand in Nigeria are the biggest in the whole of Africa
