  • Features of hope and the relation to life at experts of a technical profile

    The article discusses problems of hope and the relation to life of representatives of technical specialties. Approaches to studying of hope as sociocultural and social-psychological phenomenon are briefly described. It is noted that the hope is the metavalue of human life. Authors emphasize that the fulfillment of vital events of any modality, both positive, and negative, leads to change of expressiveness of hope. In article on the basis of empirical data features of hope and the relation of experts of a technical profile to various stages of the life are analyzed.

    Keywords: hope, spheres of hope, life satisfaction, relation to life, life events

  • Features of creation of types of web portal of the national-cultural autonomy

    The article substantiates the relevance of the types of web portal of national-cultural autonomy. The architecture, functional model, information model, GUI main page of a typical web-portal of the national-cultural autonomy are given in the article. The positive effects of the introduction of a standard web portal of the national-cultural autonomy are listed.

    Keywords: information and communication technologies, web portal, national-cultural autonomy

  • Methods of analysis and selection of technology for building subsystem as part of the complex automated system (for example, SAP ERP)

    The study on the example of the choice of SAP UI Technology for the development of a subsystem of planning and actual time tracking has shown the proposed method of selecting one of the available technologies for construction of a subsystem based on a particular platform. The developed method includes the analysis of the features, advantages and disadvantages of each of the possible technologies and then a well-formalized decision-making process of choosing one of the technologies based on the analytic hierarchy process.

  • Determining the periodicity of vehicle maintenance

    The paper discusses methods for determining the frequency of maintenance (MOT). The proposed method allows to simulate the technical condition of the vehicle under various conditions and modes of its movement, taking into account the random nature of the changes of various factors. The proposed method takes into account the probability of failure for a given range of the vehicle (TC), as a generalized description of the technical condition of the car, indirectly affect most of its domestic individual characteristics and external destabilizing factors. The novelty of the method lies in the fact that takes into account not only the standard run, and an optimum set of operations in a particular embodiment, service and repair. To allow for individual TC correction coefficients of standards periodicity TO calculated using fuzzy logic.
