Such a major transformation of the new type of a society significantly affects the organization of education as the basis of Industry 5.0. The paper examines these inevitable changes, covering all the essential elements of personalized education and requiring the combined efforts of all key stakeholder groups, including governments, education and training providers, industry, support bodies, the wider community and, most importantly, students themselves.","PeriodicalId":330635,"journal":{"name":"System research and information technologies","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132039731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a numerical analysis of this problem, it is proposed to use the method of two-sided approximations based on the method of Green’s functions. After replacing the unknown function, the boundary value problem is reduced to the Hammerstein integral equation, which is considered as a nonlinear operator equation in a semi-ordered Banach space. The conditions for the existence of a single positive solution of the problem and the conditions for two-sided convergence of successive approximations to it are obtained.

The problems of heating the mixture, melting the polymer and determining the velocity of the phase transition boundary in the conditions of a mobile solid mixture due to the rotational motion of the mechanism that feeds the mixture into a cylindrical channel are considered.

The results of comparison for depressed sewer crossings using the developed model are demonstrated both for the whole multitude of potential undesirable events and for the specific scenarios of sabotage, landslide, operational damage.

A computational experiment performed for a two-dimensional system of semilinear parabolic equations of the “reaction–diffusion” type confirms estimates for the convergence of iterations established in the proof of this formula.

The ethnocultural civilizational distribution of the countries is specified on the basis of the fuzzy cluster method. The mathematical model of fault lines between civilizations is elaborated, which affords the opportunity to estimate and analyze the quantitative values of these faults. Formally, the developed model offers the way to determine evolutionary regularities, systematize and econometrically verify the defining characteristics of actual civilizational clashes. The results of an analysis and comparison of modeling data of intercivilizational faults in 2008 and 2018 revealed the tendencies of individual civilizations to unite and clash, and the effect of these faults on the global conflict as well. The dependence of global threats on the proliferation of weapons and their individual components is assessed. The conflict effect on the socio-economic indicators of clashing civilizations is determined. The correspondence of the modeling outcomes to the real state of intercivilizational faults is verified by comparison with actual historical data.
