The article is devoted to the study of crowd behavior in public buildings during a fire. A method for evaluating the effectiveness of organizing the evacuation of people from a public building is proposed, which makes it possible to take into account the spread of panic among evacuees. The method is based on the development of an evacuation simulation model that takes into account the impact of certain factors on the degree of people's panic, which implements an agent-based approach. The proposed method allows, when describing the psycho-emotional behavior of each agent separately in the process of evacuation, to evaluate the effectiveness of organizing the evacuation of the crowd as a whole. The simulation results on the example of a shopping and entertainment center show that possible panic conditions of evacuees can affect the efficiency of evacuation.

This article analyzes the assessment of the signs leading to the possible destruction of the investigated building structure. Using the mathematical basis for diagnosing the destruction of a building structure, it is possible to determine how the signs that affect the destruction of the structure or their groups affect the determination of the degree of destruction. Applying the Bayesian approach to determining the degree of malfunction of a building structure and its destruction, a comparison of the probability of destruction of each investigated building structure is given. It was found out how the calculated probability of each structural failure was affected by the presence of each feature and what contribution to the increase or decrease in the probability of an accident was made by the analyzed feature affecting the destruction of the structure. It is proposed to use artificial, model destruction of building structures to determine the influence of various factors on determining the degree of destruction, so to speak, in its pure form and in various variants. In addition, you can get test cases to test the effectiveness of various diagnostic methods and find out a number of theoretical questions. Considering this, and the other goals listed above, models were built. An assessment of the influence of a feature that affects the probability of destruction of a building structure in one of many ways is shown. According to the proposed methods, the values of the sign affecting the destruction for the structure are determined. The probability of destruction is determined.

This article discusses the solution of the problem of monitoring contact information in a social network and determining the personality psychotype based on it. Most of the material proposed by the developers works with English-language texts to determine the emotional coloring, their classification and, to a lesser extent, clustering. The approach proposed in the article is based on the use of the K-means method to solve the clustering problem of Russian-language texts and subsequent comparison with the results of working with the same data of an already trained model. During the work, was developed an effective method of parsing for collecting data. A proprietary data set has been collected and its processing and detailed analysis have been carried out. The result of the study allows us to make a primary assumption about what kind of psychotype a particular person has. It is quite difficult to determine the accuracy of the results of the task, since there is no predefined correct answer in machine learning without a teacher, and determining the psychotype is a difficult task from the point of view of psychology. All program code is written in the Python programming language.
