The use of machine learning methods to control heat supply systems is a pressing issue worldwide. The aim of the work is to develop methods for intellectualizing the operating modes of individual heat supply units (IHU) to improve their efficiency and reliability. To achieve this goal, the following tasks were solved: creating and debugging methods for diagnosing IH operating modes; using the cluster analysis method, in particular the K-means algorithm, to identify pre-emergency situations at an early stage; analyzing the relationship between outdoor air temperature data and the pressures of direct and return network water in IHU operating modes using Novosibirsk as an example. The most important results of the work include dividing the measured parameters into five clusters, each of which characterizes a certain IHS operating mode. This was confirmed by the "Elbow Method", which determined the optimal number, which made it possible to significantly improve the forecasting of emergency modes. Studies have shown that a sharp increase in outdoor temperature leads to an increase in the pressure of direct network water, which can cause accelerated wear of heating networks due to the peculiarities of weather-dependent automation regulation. Introducing additional parameters into the initial data, such as the service life of heating networks and weather conditions, can improve the accuracy of forecasts. The significance of the obtained results lies in the possibility of early detection of emergency and pre-emergency modes of IHU operation, which helps prevent accidents and reduce repair and maintenance costs.

This article represents the first part of an analysis that Academician Eugen Simion sets out to unravel on Duiliu Zamfirescu’s works. This author’s novels are the target of this analysis although his correspondence (his letters) is found to be of high knowledge, interest and especially of high literary value. Much information is taken for this analysis on Zamfirescu’s novels out of his letters written to Titu Maiorescu, among others. Duiliu Zamfirescu is found to militate against our people’s indiscrete copying of other peoples influence; in this direction, he gives Sweden as an example of rising on its own. As regards art, Duiliu Zamfirescu is ambiguous and abstract. He rejects the use of the unbelievable in epics. His good intentions regarding his continuously renewed methods and substance that ought to be applied in novels are again found in his letters. He is against I.L. Caragiale, he dislikes the latter’s skepticism and irony, and especially the triviality. Duiliu Zamfirescu is found to be a complicated spirit, an amount of contradictions. Thus, his realism is balanced, lacking cruelties and refined psychology; his intentions go towards intellectualization but does not make appeal to any social sciences. His ethicism places him among visionaries with high unrealistic ideals. Readers can easily take interest in his novels because the narration captivates one’s interest. The writer however obviously does everything to compromise his characters that he programmatically hates. More objectivity and less triviality in his characters’ language would have made his characters achieve a more visible outline.
