A linguistic identification of a system controlled by a fuzzy-logic controller is presented. The information about the behaviour of the system, concentrated in time-series, is analyzed from the point of its description by linguistic variable and fuzzy subset as its quantifier. The partial input/output relation and its strength is expressed by a sort of correlation tables and coefficients. The principles of automatic generation of model statements are presented as well.

The purpose of the article is to determine the influence of the socio-economic and socio-political situation in the Orel region on the level of social tension. The research methodology is a sociological analysis of the respondents' answers about the socio-economic and socio-political situation in the region, as well as the level of social tension using two-dimensional analysis and correlation tables. As a result, the importance of conducting monitoring sociological studies of the main indicators of the social development of the region has been substantiated. It was revealed that the population of the region believes that the state of affairs in the economic sphere in the region is much worse than in the country as a whole. Despite the fact that the majority of respondents note an improvement in the political situation in the region, the fact that every third resident of the region declares that it has deteriorated is quite alarming. The authors come to the conclusion that dissatisfaction with the socio-political and socio-economic situation directly affects the civic position of the population, affects the growth of social tension. It is summarized that social tension is a complex multifactorial phenomenon that cannot be interpreted unambiguously. Therefore, to monitor it, constant research should be carried out.

Correlation Tables

1. Percentages of fat, solids not fat and protein were determined in over 700 samples of mixed milk from 15 herds during 1925–26. In the case of fat content, nine herds produced one or more samples below 3 per cent., one herd recording 25 per cent, of samples below this limit. With regard to solids not fat, twelve herds produced milk containing less than 8·5 per cent, on one or more occasions, the highest percentage of deficient samples recorded being 40.2. Frequency distributions of fat, solids not fat and protein percentages in the samples analysed, are given, together with standard deviations, and mean percentages with probable errors for these three constituents.3. Correlation tables of fat with solids not fat, and protein with solids not fat have been prepared, and graphs illustrating the variations are given.
