Description
In this article we have developed the optimum speed diagrams for small movements of electric drive’s actuating device. We have identified analytical dependences of position of automatic regulation of system control signal of time, which allows to form the optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision

DEFINITION OF ELECTROMAGNETIC ENERGY AND MOMENT IN THE CASCADE ELECTRIC DRIVE
DescriptionThe problem of calculation of arguments of the controlled cascade electric drive is reviewed. For a basis the electric drive is taken by the designed writers. For definition of the moments the method grounded on electromechanical transforming of energy is proposed. On an example of a present construction the values of currents of a stator and rotor and phase angles of these currents were retrieved. It has allowed to find the energy, accumulated by the device, in the given instant. Utilizing this result, the instantaneous moment was defined. The introduced mathematical model realized as the program in environment Delphi. Inaccuracy for an audit example did not exceed 10-15 %

ORGANIZATIONAL-ECONOMIC APPROACHS TO ESTIMATE THE FEASIBILITY OF INNOVATIVE-INVESTMENT PROJECTS
DescriptionIn this article we propose a general theoretical model of estimation of the feasibility of an innovation-investment project. For specifying a general model to estimate the feasibility of a project we have highlighted the stages of development of projects in the aerospace industry. Organizational-economic approaches to estimation of the feasibility of projects to create rocket and space technology are presented in terms of algorithms. They take into account the specifics of the space industry, by virtue of which such projects have both innovative and investment components

Description
In today's economic conditions, a bankruptcy prediction is performed using a methodological analysis apparatus of economic and financial condition of the entities. Methodical provision of financial analysis is a tool that is necessary for the most effective management of financial and economic activities of the organization, industry, and region. The task of predicting bankruptcy as an independent problem originated in developed countries after the Second World War. Our transition to a market economy has made an actual assessment of the financial condition of businesses. As a result, in practice, there are many financial analyses of foreign and domestic procedures. The problem of determining signs of insolvency of the enterprise is very complex. Forecasting of bankruptcy can be made with using various techniques, approaches and methods

KEY STAGES OF STATISTICAL METHODS DEVELOPMENT
01.00.00 Physical-mathematical sciences
DescriptionThe first statistical publication – the Fourth Book of Moses, “Numbers” in the Old Testament. We trace the development of ideas about the statistics until the twentieth century. The present stage of statistical methods began with parametric statistics by Pearson, Student, Fisher. Scientometrics of statistical researches provides an indication of the accumulated results. Nonparametric statistics appeared in the 1930s, applied statistics in our country - at the turn of 1970-80. We have discussed what gives applied statistics to national economy. Also we have told briefly about the history of statistical methods in Russia (until Kolmogorov's time)
