In the study of polydisperse materials, most of the experimental particle size distributions were obtained on bounded intervals. In these cases, it is also desirable to use bounded models with different shapes to simulate the results of studying polydisperse and powder materials. The beta distribution is often used to approximate results due to the fact that this distribution contains many forms for displaying realizations on a limited interval. With the development of computer technology, there has been an increased interest in the use of beta distribution in the modern practice of analyzing results. Meanwhile, there remains a limitation in the use of the beta distribution that is associated with the choice of distribution shape. The possibilities of using known shape measures for mapping beta distribution in this paper is discusses. On the example of the space of shape measure of kurtosis and skewness, the limited use of only probabilistic measures of shapes is illustrated. It is proposed to use the entropy coefficients as an additional informational parameter of the beta distribution shape. On the base of a features comparison of the entropy coefficients for biased and unbiased beta distributions, recommendations for their application are given. By using the example of beta distributions mapping in the space of asymmetry and the entropy coefficient, it is shown that the synergistic combination of probabilistic and informational measures of the shape allows expanding the possibilities of estimating the shape parameters beta distributions. Two methods to display the positions of realizations of beta distributions is proposed. There are trajectories on a constant ratio of shape and realizations position curve on equal values of one parameter. In particular, the features of the choice of beta distributions with negative skewness are discussed.

This article is devoted to the study of the current topic - the importance of digital etiquette as an employee competence. The percentage of modern employee's communications in the online space is increasing, more and more work issues are solved using computer technology and electronic systems. This trend requires the development of a new digital culture of communication, which includes the rules that are necessary to build clear business relationships. In order to form a relevant, understandable and succinct set of recommendations, it is required to assess the current level of knowledge of digital etiquette. To do this, a survey was compiled that included questions defining human behavior in various situations that may arise during online business communications. Based on the survey with 120 respondents, recommendations on business etiquette topics were developed.

The improvement of modern computer technology to achieve fundamentally new indicators can be carried out on the basis of various approaches. One of such approaches is the application of methods of physical informatics. Therefore, this paper considers the support of ensuring “digital immortality” based on physical computer science methods. On the basis of Wiener random processes, measures are proposed to ensure the security of computer nodes to ensure “digital immortality”. The calculated ratios from physical informatics adapted to determine the requirements for the design of information systems to ensure the digitalization of the brain are given.

Abstract With the advancement of the times, computer technology is also constantly improving, and people’s requirements for software functions are also constantly improving, and as software functions become more and more complex, developers are technically limited and teamwork is not tacitly coordinated. And so on, so in the software development process, some errors and problems will inevitably lead to software defects. The purpose of this paper is to study the intelligent location and identification methods of software defects based on data mining. This article first studies the domestic and foreign software defect fault intelligent location technology, analyzes the shortcomings of traditional software defect detection and fault detection, then introduces data mining technology in detail, and finally conducts in-depth research on software defect prediction technology. Through in-depth research on several technologies, it reduces the accidents of software equipment and delays its service life. According to the experiments in this article, the software defect location proposed in this article uses two methods to compare. The first error set is used as a unit to measure the subsequent error set software error location cost. The first error set 1F contains 19 A manually injected error program, and the average positioning cost obtained is 3.75%.
