A modification of the PageRank method based on link ranking is proposed to evaluate the research results of subjects of the scientific space, taking into account selfcitation. The method of reducing the influence of self-citation on the final evaluation of the results of research activity of subjects of the scientific space is described. The evaluation of the results of research is calculated using the modified PR-q method, taking into account self-citation as a solution of a system of linear algebraic equations, matrix of which consists of coefficients determined by the number of citations of publications of one scientist in the publications of another scientist. The described method can be used for the task of evaluating the activity of the components of the scientific space: scientists, higher education institutions and their structural units. For the task of evaluating the research activity of subjects of the scientific space, a method based on link ranking (PageRank method for web pages) and taking into account the selfcitation of scientists is proposed. The latter allows for an adequate assessment, taking into account the abuses associated with the authors’ excessive self-citation. The essence of the constructed method lies in the construction of a system of linear algebraic equations, whose coefficients of the matrix reflect the citations of some scientists by others in the citation network of scientific publications. The value of the coefficients of the matrix of such a system of linear algebraic equations is subject to certain restrictions, which allow to reduce the influence of the factor of excessive self-citation of the author on his overall assessment of research activity. The described method can be used to calculate the complex evaluation of the components of the scientific space: the scientist, the institution of higher education and its separate structural units. Evaluating research results provides an opportunity to verify the relevance of the research process to the goals identified at the planning stage and, if necessary, to adjust the progress of those studies. Also, the calculation of research evaluations of the components (objects and entities) of the scientific space is a powerful tool for managing research projects.

The aim of the article is a comprehensive approach to addressing the digitalization of education in the Republic of Kazakhstan based on identifying problems in this area, forming priority tasks and possible ways to solve them. Implementation of IT-programs in the learning process making serious additions to the pedagogical requirements, ethics, and discipline of students also the content of the disciplines. All these aspects are becoming especially relevant today when the quality of education is becoming a strategic task and the key to the successful development of the country’s economy in the digital era. The article touches on the problems of the modern “digital” generation, its dependence on communication in social networks and instant messengers, the impact of this dependence on health and the level of knowledge. The algorithm for educational technologies will be the main educational goals: the ability to think outside the box, be creative in solving problems, and develop logic and intelligence. Therefore, to formulate requirements for training ICTs, it is necessary to implement measures to assess the effectiveness of implemented programs based on experimental data. Such studies are being conducted today to improve the quality of the educational process, which means that they can be used for ICT. In conclusion, if to base on the results of the survey, the main problems were identified and a number of tasks were set for a deeper study, a general idea was formed on the scope of the forthcoming work and the goals for its achievement.

A system for recognizing surface defects in marble slabs is proposed. The pattern recognition method based on segmentation methods was further developed. The algorithm of the recognition system. The article describes methods for determining damage from digital images on various hard surfaces. Research in this field is relevant for a wide range of industrial enterprises that specialize in the production of various kinds of materials: parts, marble slabs, building materials, etc. To solve this problem, it is proposed to use the k-means clustering method. It has been experimentally established that Gaussian blurring algorithms, the Hough transform, and the Kenny algorithm are best suited for recognizing defects on the surface of a marble slab. The developed complex method based on the theory of pattern recognition allows you to quickly identify defects and damage on the surfaces of marble slabs. On the basis of the method, a system for understanding defects is implemented in software. The main stages of the system are described in the article. The results of the analysis of the image of the surface of the marble slab on a specific example are presented.

The structure and functions of the mechanisms of development and erosion of competencies in innovative projects for the implementation of information and communication technologies in the digitalization of society are considered. The factors of development and erosion of competencies are determined. A model for assessing competence and competencies for the successful implementation of information and communication technologies using the example of project management and digitalization programs has been built. The proposed model for the development of competence of the project team for the creation and implementation is based on a balance of factors for the development of competencies of the innovative project and their erosion in the implementation process. The study of factors of development and erosion of competencies in the management of innovative digitalization projects allows us to adequately respond to changes in the profile of competencies of innovative projects. At the same time, analysis allows the project manager to form effective programs for acquiring certain competencies for team members and other interested parties. The proposed model of the factors of development and erosion of the competency system is tested on examples that confirm its adequacy and effectiveness. This model for the development and erosion of the competencies of the digitalization project team is based on a balance of factors for the development of competencies of the innovative project and their erosion in the implementation process.

At the same time, analysis allows the project manager to form effective programs for acquiring certain competencies for team members and other interested parties. The model of factors of development and erosion of the competency system proposed by the authors is tested on examples of applying the Agile methodology at the level of the project management department of the Kiev National University of Construction and Architecture. The implementation confirmed the adequacy and effectiveness of the model and methods of analysis of the development and erosion of competencies, and as a consequence of competence. As a direction for further development, it is necessary to determine the methods and algorithms of the Leader’s proactive response to the development and erosion of competencies, forming the corresponding competencies of team members ensuring the success of innovative projects.

The article is devoted to experimental estimation of interference parameters. The article discusses LTE technology, the main parameters and services of LTE technology, and calculates the internal parameters. Introduction of LTE technology in the Republic of Kazakhstan is currently an urgent topic. LTE technology is one of the most high-speed mobile access technologies. The main advantage of LTE is the so-called “open” Internet access. This means that a mobile network subscriber can access the Internet using the most convenient device at the moment – a mobile phone, PDA, smartphone, or laptop that has the most suitable characteristics for the current exchange of information. It is established that the losses depend on the distance between the transmitter and the antenna. The results obtained during this experiment showed that when using cellular communication equipment in the service area with a radius of about 1.9 km, communication in the direction of the AC-BS will be established at 90% of the time and places with a signal-to-noise ratio at the receiver output is no worse 16 dB As can be seen from the calculations, LTE technology provides effective radio coverage and can operate at high speeds, for subscribers located in the center and at the cell border to have a fairly good signal level.
