The most important task of the admissions committee of any university is to advise applicants on admission to the specialties available at the university. In this article, an automated information system has been developed, which, based on the applicant's questionnaire, allows you to form recommendations when choosing a training specialty, taking into account the applicant's personal preferences. Artificial neural networks are proposed to be used as a method of choice, and the multilayer perceptron (MLP) was the model of the neural network.

With the development of industry and science, the size of the patent base is growing, as well as the number of patent applications received by the agencies regulating the issue of patents is growing. Each patent application must be checked for the uniqueness of the patented technology, for this, the patent office experts need to search the patent database and find analog patents. In the absence of analog patents, this technology can be considered unique and accepted for patenting. Since the patent database of various departments can number tens of millions of patents, such a patent search and evaluation of the uniqueness of the patented technology can take a very long time. The existing systems do not meet all the requirements and do not have the full necessary functionality. This article describes the development of an automated system for searching for analog patents in the patent array.

During operation, the pipeline is threatened by various geological hazards, especially in regions with permafrost, where freeze-thaw disasters have a significant impact on the integrity and safety of oil and gas pipelines. Therefore, at the design and construction stage, it is advisable to analyze various methods of laying pipelines, taking into account the topographic environmental conditions, as well as the effect of frost rise and thaw on the soil of the pipeline foundation. An analysis of the existing design schemes for the construction of pipelines, the conditions for passing the route of the projected pipeline, the characteristics of the pumped hydrocarbons makes it possible to justify the choice of a construction method that can ensure the stable position of the oil and gas pipeline both during the construction period and during its operation.

The article considers internal adjustable sun-protecting jalousies from their different functional efficiency pant of view. It is noted, that besides their main sun-protective function, adjustable jalousies possess some other functions, depending on the position of their horizontal planks. These functions can be successfully used for microclimatic internal environment creation of comfortable. These are natural lighting function, psychological contract with surrounding environment function and function of visual isolation, i.e. “privacy”. and so on. All the above functions usually have maximum efficiency of their qualities in the case of their individual consideration. This, as a rule, is not practically reasonable. That is why this work is aimed on optimum combination of the man functional characteristics of horizontal sun-protecting jalousies under necessity of their mutual consideration, i.e. in achievement of their functional universality.

This paper presents an information model of a relational database developed by the authors, designed to take into account the teachers workload of an educational organization. The identification of the subject area entities, their decomposition and the relationships identification between them are carried out. The constructed database model was brought to the Boyes - Codd normal form. Based on the designed database schema, its physical implementation and filling with test data was carried out. The results of test queries showed the developed model adequacy and the its practical applicationp ossibility. It is currently in trial operation at the Department of Information Systems and Computer Modeling, Volgograd State University. With minimal changes, the developed database schema can be applied to account for the teachers workload in various educational organizations.

In this work, the phonon format of graphane nanoribbons is calculated in the Hamiltonian formulaism. The geometric model is presented in the form of a graphene plane with hydrogen atoms attached to it. The unit cell of graphane contains two carbon atoms from solid graphene and two carbon atoms. The curvature of the graphene plane as a result of attachment to hydrogen atoms and hybridization of the outer electron orbitals of carbon atoms from sp2 to sp3, as well as the interaction between hydrogen atoms, are not taken into account. Analysis of the obtained phonon spectra shows that, for any type and width of graphane nanoribbons, there is a gap between acoustic and optical vibrational modes, in contrast to graphene, which can serve as an indicator for a given structure. Also, for the material under study, the values ​​of the speed of sound and the Debye temperature were calculated.

The article discusses the features of environmental safety management systems of organizations in the electric power sector, and also presents an approach to their improvement. The authors substantiate that an important aspect of improving the environmental safety of electric power companies is the integration of quality and environmental management processes in the organization. Based on the analysis of scientific literature and the regulatory framework, the problems of integration of environmental management systems, quality management and organization management are identified. As one of the approaches to improving the environmental management system of electric power industry organizations, a management model of an environmentally-oriented organization based on the PDCA cycle and a quality management system, as well as scientifically based principles of its construction, is proposed. The key advantages of the model are: an expanded methodological base in comparison with the models of environmental management and quality management based on the Deming сycle "Plan-Do-Check-Act" the possibility of effective integration with the general management system; decision-making based on various factors of the external and internal environment of the organization.
