The article discusses the application of statistical modeling for the durability prediction of electronic equipment. Durability indicators are one of the important characteristics of onboard electronic equipment of spacecraft with long terms of active existence. The purpose of the study is to improve the quality of design work by improving the method of calculating the life of electronic equipment, taking into account the probabilistic characteristics of the life components of its electronic components. The object of the study is a typical procedure for calculating the life of electronic equipment at the design stage from data on the characteristics of the durability of electronic components. The subject of the study are methods, models and algorithms applicable to the analysis of the design level of the durability of electronic equipment. To study the effectiveness of statistical modeling, software was developed and the reliability of its work was tested. With the help of this software, computational experiments were carried out. Comparison of the results of statistical modeling and calculations by a typical methodology made it possible to identify a number of significant limitations of the deterministic method. In the standard methodology, it is assumed that the variation coefficient of life is a constant for all electronic components. But the analysis of Data Sheet of electronic components has shown that the values of the variation coefficient can be different for electronic components of different types. The calculations have confirmed the need to take into account the values of the variation coefficient of life in predicting the durability of electronic equipment. In addition, in the standard methodology it is assumed that the life of electronic equipment that contains electronic components with the same life values will be equal to the life of electronic equipment that contains only one such electronic component. Computational experiments have shown that the life of electronic equipment that contains electronic components with the same life values will be less than the life of electronic equipment that contains only one such electronic component. Based on the studies, the scope of the standard methodology was determined and the effectiveness of statistical modeling was proved. However, the results obtained by the statistical modeling method should be corrected by the results of the tests and the controlled operation of electronic equipment.
Objectives: Development of a mathematical model and its implementation as a computer program for diagnostics and prediction of progression of the most widespread cardiovascular diseases; the program is to model different variants of disease progression for an observed patient, and to select individual recommendations for correction of his or her lifestyle, regimen and diet. Methods: Combination of technologies of neural networks and expert systems with a resulting synergistic effect. Results and Conclusion: Investigations of the developed mathematical model showed that it is able to reveal new knowledge which is yet unknown to medical science. In the course of software experiments performed by means of a diagnostics-and-prediction system, we revealed the facts showing that modern medical practice patterns of giving one and the same recommendations to all the cardiac patients without exception (including keeping to a hypocholesteric diet, giving up pernicious habits, limiting coffee and alcoholic drinks, losing weight and limiting intellectual and physical activity) are not always correct. Our investigations showed that some of these recommendations are not just unhealthy, but harmful for a number of patients. The neuro-expert diagnostics-and-prediction system presented in this paper allows doctors to reveal such non-typical patients and to develop individual recommendations especially for them.

The concept of entrepreneurial university and role of culture in its formation is analyzed. The understanding of academic entrepreneurial culture, as culture integrating the academic and entrepreneurial values is offered. The article reveals that methods for diagnosis organizational culture in enterprises are not suitable for an assessment of university culture. The suggestions are made for development an adequate technique for the diagnosis organizational culture of entrepreneurial university.
This article analyses the concept of entrepreneurial university and the role of culture in its formation. Theproblem of appropriate diagnostic method is being risen. The article discusses the findings of organizational culture assessmentby means ofdiagnostic methodof R.Goffee and G. Jones in the two universitiesof Nizhny Novgorod. The way ofdevelopment of congruent method of the university organizational culture diagnosis is being offered.
