Inexpediency of use of probability of correct diagnostics as a quality indicator of diagnostic algorithm is shown. The new indicator - the prognostic strength based on Mahalanobis distance between classes is offered and studied. We have found asymptotic distribution of the prognostic strength; the way of testing of adequacy of its application has been specified. In a problem of testing of two simple hypotheses the prognostic strength connection is established with Hellinger distance
Linear estimators of the probability of density in the spaces of an arbitrary nature and particular cases – nuclear, histogram, the Fix-Hodges type estimates are introduced. Consistency and asymptotic normality of linear estimates are proved under natural conditions. It is shown that the probability of the area can be found by linear density estimates. A special case of a finite set are discussed, it was found that sample mode converges to the theoretical one
We introduce the concept of "controlling organizational-economic methods". We define the terms in the sequence "the problem - the model - the method - the conditions of applicability". We have described the basic organizational-economic model of industrial firm; by means of this model we have discussed the problems of development of modern organizational-economic methods. We have demonstrated the relevance of the theory and methodology of organizational-economic modeling. For example, we consider the application of statistical methods at various stages of the life cycle of the product, the problem of internal risks in an industrial firm and accounting for inflation in the analysis of activities of the organization
For strategic and operational management tasks in the aerospace industry we use a variety of organizational-economic models and methods. Their set is called an organizational-economic support. In this article we discuss the approaches to the development of adequate organizational-economic support in the aerospace industry. In particular, we consider the problems of estimation of the effectiveness and management of innovation-investment projects to create aviation and space technology
The article discusses the structural and control systems schematics and voltage stabilization in phase bridge circuits solar power inverters with PWM output voltage and improved performance
The article discusses structural schematics power circuits and voltage stabilization systems of converters with improved operational and technical characteristics
The requirements for the project design stages of creating rocket and space technology are specified. The algorithm of estimation the feasibility of such projects is proposed based on their innovation and investment components
This article presents theoretical problems of constructing distance detectors as a relay of full impedance based on converters with a rotating magnetic field. A variant of the practical implementation of device and test results is proposed
Based on local semantic information models, we have examined the dependence of the dynamics of the displacement of the pole positions of celestial objects. We have also developed and differentiated an analysis of ASK-pole modeling of dynamics within sixty-year cycles of reference points and substantiated reasons for the population inversion and singular states in the dynamics of the pole
The mathematical model presented in this article is designed to assess the probability of occurrence probability of technological failure potato harvester according to the specific conditions and usage
