Data mining methods were used to analyze publication activity of the university staff on the example of the Petrozavodsk State University (hereinafter referred to as PetrSU). In order to identify employees groups with similar indicators of scientific activity, they were clustered. As a result, teaching staff was divided into eight clusters, three of which included employees representing both present and future of science at Petrozavodsk State University, and others that would strive to get into these groups. The presented results of indicators’ statistical processing can be useful for university self-analysis. The university management could draw a conclusion on a current state of scientific activity, both of an individual employee and of the organization as a whole. This will allow to make scientifically-based management decisions in order to improve scientific performance of the organization.

The models of resolution of the main types of intrapersonal conflict are given. They are all connected with the choice of the object or action (equal or different valence) of two equiprobable (still attractive). The models were built in the discrete event approximation. It is based on the assumption that the opinion of the subjects about the usefulness of the objects undergoing random fluctuations at each step. Their attraction is the same only average. The second basic hypothesis is that the subject intuitively changes its assessment of the probability of selection after the change of the attractiveness. The transformation probability is modeled using Bayesian theory of decision-making. Numerical experiments showed the viability of such model. It is obtained that in the end, the situation with the choice of is permitted in one direction or another (equiprobable at the level of the final decision). The time resolution is inversely proportional to the width of the fluctuation of attraction. In the work it is also investigated the influence of evaluation by the subject of the significance of the objects. Obtained as a very low evaluation, and Vice versa, too high, hinder the resolution of conflict. The minimum completion time is achieved a little distant relation of the subject to the object (process) conflict. The results are as purely situational, specific significance, and the overall methodological. The presented models allow for an easy generalization to more complex cases involving a variety of factors influence and can serve as a basis for such studies.

In the paper there are examined intrapersonal conflicts associated with the mandatory selection of one option from two, equal their relative attractiveness. To study the effect of social environment we combined two models. The first was the previously developed model based on the theory of Bayesian model intrapersonal conflict one subject. Second was the model the spread of the epidemic presented in the base package of the agent-based modeling AnyLogic. In the numerical experiments it is studied as a manifestation on the intrapersonal level, social aspects of the environment, and Vice versa, the impact of these conflicts on the society. Found that the level of this impact strongly depends on the social value of objects of choice. If this objects important only for the individual, the near social neighbours can only shift the final probability of selection and to reduce the resolution time of the problem. The opposite effect is small. If the conflict causing problem is socially significant both for the subject and its environment, the picture changes dramatically. An association of individuals with the same choice as the conflict and the formation of clusters of two types are started with the development of the conflict in the study community. There is growth of these clusters and their absorption of each other. It was studied several scenarios final solution to the problem, such as the transformation of intrapersonal conflict in intergroup one and confrontation of the formed sub-groups, or complete absorption of one type of cluster other with the winning one of the variant. The obtained results point to the need for the study of social conflicts to pay attention to intrapersonal and the possibility of escalating into intergroup.

The article discusses research methodology of intrapersonal conflict by using the affective component of appropriate social attitudes. We analyze three kinds of internal contradictions. Which are classified by K. Levin as the conflict of ""Desire-Commitment"", ""Avoidance-Avoidance"" and ""Commitment-Avoidance"". They are all connected with a choice of appropriate object or action (equal or different valences) of the two equally probable. The affective component of perception of such internal contradictions is determined by the technology of semantic differential on the basis of the survey conducted at the end of 2016 among students DSTU. For the interpretation of the results used the previously developed technique. The distribution functions of the emotional perception of those conflicts are described in article. Which were calculated as in the linear approximation and a nonlinear lookup psychosemantic model. It is obtained that the average affective perception of the studied conflicts neutral or close to that. But the researched audience is very heterogeneous in its emotional attitude to such conflicts. The distribution function is strongly smeared almost all over the range of levels of perception. While approximately half of the respondents are characterized by positive attitude to internal contradictions. This suggests that positive role of conflicts associated with the resolution of problems of an appropriate level subconsciously affects on estimates. A few unexpected results were obtained by a comparison of the perception of conflicts ""the Desire-the Desire"" and ""Avoidance-Avoidance"". Distribution function for the problem of the choice of two positive options is being shifted to the left, in the negative direction, compared with the function for a choice of two unattractive possibilities. The work has shown the promising use of such figure as the affective perception for researching of intrapersonal conflict. The obtained results possess as General methodical so purely situational, specific significances.

During the motion analysis (design, model, body) a certain amount of data in the form of accelerometer readings with increments of 0.001 seconds – about a million of lines. At any instance of time we have to solve the problem of determining the acceleration of specified point of the solid body, taken as the pole. Therefore, our goal is to reduce the time for each iteration for determining the acceleration of the given solid body pole.

The paper presents the results of a comparative analysis of estimates of the levels of emotional perception, is satisfied in full and shortened semantic scales. The studies were performed on specific experimental data obtained in the measurement of deprivation attitudes of students Academy of architecture and construction DSTU at the end of 2016. It is found that the decrease in the number of signs in the semantic scale to the optimum leads to small changes in the assessments of emotional perception. At the individual level the changes are mostly (70%) not more than 10%,and in the whole group even less.
