S.I. Barkalov, post-graduate student of the Department of Information Technologies and Computer Systems, Sevastopol State University; Sevastopol
The process of knowledge acquisition and assimilation is considered on the basis of the existing learnability notions. The learning process model scheme is proposed within a systematic approach, taking into account the factors influencing the level of knowledge acquisition under the IDEF0 standard. The process of obtaining and assimilating knowledge is presented in the factor-subject space «student-teacher-environment», where information is transferred into knowledge. The formulations of «translation» and «assimilation» of knowledge in terms of the contextual system model are proposed. It was found that to refine the model it is advisable to take into account the factors (external and internal) affecting the level of knowledge assimilation by the recipient. An enlarged learning process model is formalized, with the scheme of the decision-making process to assess the learning process efficiency proposed on its basis.
Keywords: learnability, factors of learnability, educational process model, educational process efficiency.

The relevance of the study is due to the fact that, thanks to the emergence of educational information systems and Big Data technologies, for the first time in history, pedagogy got a chance to quickly, continuously and in full register a vast array of observations of the learning process, behavior and progress of students. The purpose of the work is to present the Data Driven methodology in the context of the transition from traditional descriptive analytics to analytics for decision making. The empirical basis of the study was the works of David Nyemi «Learning Analytics in Education», Khintan Bhatt, Preity Srinivas Saya, Sidath Liyanag «Utilizing Educational Data Mining Techniques for Improved Learning: Emerging Research and Opportunities», as well as University research 20.35 «Intellectual analysis of educational data». In the article, the author reveals the questions, what is the Data Driven approach in general and in training in particular; why it is important to measure change and how to do it; what questions you need to ask yourself before building an analytics system for a training program; how data is collected for training analytics. The practical significance of the research results lies in the fact that the presented Data Driven methodology, as big data analytics in education in the context of digitalization, will allow automating many routine processes in the educational analytics system, identifying problems at an early stage and acting preventively.

e-mail: zaitsev.zaw@yandex.ru
The article presents a brief description of the reasons for the failure of machine drives based on gear transmission, as well as worm-class gears, as a result of their operation and the action of contact loads on the active surfaces of the teeth of the gear wheels, which leads to malfunctions, breakdowns, failures in the form of wear, scoring, galling. The existing method of calculating endurance, taking into account the variability of loads and the number of cycles of their action on contact endurance and endurance of teeth in bending is described. The analysis of methods for assessing the operational life of gears is presented. The necessity of developing a procedure for assessing the operational life under condition of the spiroid gears wear limit is substantiated.

The operational and service life of aviation equipment and its components are the most important indicators characterizing the duration of safe operation of products, expressed in flight hours and calendar terms. The aircrafts of airborne early warning and control (AEW&C) systems have large-sized radiotransparent radomes (RTR) of radar station (RS) antennas with a unique frameless honeycomb structure. When creating the domestic AEW&C aircraft, the developers solved the problem of both selecting the optimal RTR design and establishing the designated operational and service life. This required a significant amount of testing of samples and full-scale sections. The studies carried out to assess the influence of external factors on the reduction of strength characteristics, allowed to make a prediction on the evaluation of the designated service life, and to obtain materials in the process of operation to substantiate the possibility of extending the service life. The result of the conducted research was a step-by-step extension of the designated service life, which has now exceeded the originally established indicators by a factor of 4.
Keywords: AEW&C aircraft, radio-transparent radome, operational life, service life, RTR durability characteristics σотр, σизг, external factors.
