The Stefan-Boltzmann law describes the resulting heat transfer by radiation between two bodies, where the heat transfer coefficient is a function of the body surface temperature. An algorithm and software for solving the heat conduction problem using the finite element method were developed, and the influence of external impacts on the temperature field distribution in the vicinity of an insulated circular hole in the center of the body was studied. The temperature fields were investigated for various boundary conditions in the hole of the plate and the corresponding isotherms were given.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135441095","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}

Further development of these concepts involves the search for new research approaches and techniques. First of all, this concerns cartographic research methods, which are key in identifying the main elements of the territorial structure of the ethno-cultural space – cores and contact zones. The aim of the study is to develop new cartographic techniques for identifying elements of the territorial structure of the ethno-cultural space of Russia on the example of the regions of Siberia and the Far East based on the results of the First General Population Census of 1897. For this, the ethnic communities of this territory at the turn of the 19th–20th centuries grouped into two meta-ethnic levels. The first meta-ethno-cultural community covers the indigenous peoples of Asian Russia (North Asian cultural world), the second – immigrants to Siberia and the Far East from the European part of the country (East European cultural world). The boundaries of the nuclei of these cultural worlds and the contact zones between them are determined, for which a quantitative indicator is used – the index of meta-ethno-cultural heterogeneity, which is an analogue of the ethnic mosaic index proposed by B. M. Eckel. A map has been drawn up, which reflects two quantitative characteristics at once – the ratio of the proportion of representatives of the two considered cultural worlds and the value of the index of meta-ethno-cultural homogeneity. This map is more informative than the one based solely on the value of the index of meta-ethnocultural heterogeneity.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135957681","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}

Somons (330 in total) – the second level of this division - were accepted as the initial territorial units of the study. The dynamics for 1980-2021 of the population of the country as a whole is considered, the trends of changes in the number and proportion of urban (including Ulaanbaatar) and rural (including nomadic) populations are clarified. It is established that the main demographic indicators of Mongolia are significantly more favorable than similar indicators of neighboring Siberian regions of Russia. A significant differentiation of population dynamics by somons and urban settlements over the past two decades has been revealed. It is determined that in conditions of constant natural population growth, an important contribution to the formation of its territorial structure was made by the migration factor, primarily migration from rural areas to the capital and individual aimag centers. The basic framework of settlement is highlighted, which is formed by the capital and the centers of the aimags (as nodal elements) and the railways connecting them and the main national paved roads (as linear elements). A high effect of the importance of linear elements of the frame (highways) has been established for the concentration of the population of Mongolia. At the same time, the size of the effect of saving actual distances in the framework of the country compared to the theoretical ones is insignificant, which indicates a relatively uniform placement of centers compared, for example, with a more heterogeneous Siberia. The main problems of the settlement system of Mongolia and its supporting framework are formulated, possible directions of their solution in the future are outlined.","PeriodicalId":42592,"journal":{"name":"Bulletin of Irkutsk State University-Series Mathematics","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135957684","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}
