Original software package for psychophysiological and cognitive functions analysis of children

Psychometry plays an important role when determining the state of psychophysiological and cognitive functions in children of different ages. Goal. To deliver an original software package for a psychophysiological computer complex (PCC) “Psychomat” for implementing an online analysis of psychophysiological and cognitive functions in children of different ages. Materials and methods. One hundred eighty-four conditionally healthy school children aged 6 to 17 years were examined using a set of psychophysiological tests and original methods for evaluating higher mental functions (24 tests, 66 parameters). Results. An original software package as the computer psychophysiological complex “Psychomat” was elaborated. The norm base was determined. Also, the testing mechanism and scoring system in points for psychophysiological functions assessment were developed. Thus, it became possible to establish the patterns of cognitive and psychophysiological functions development at different ages. Conclusion. This newly created software package can be used as a test system for mass examination of children of different ages.

Cosmonaut Training Complex with Remote Access.

The paper deals with approaches to the creation of cosmonaut training complex with remote access capability based on the modern hardware and software technologies at the Gagarin Research & Test Cosmonaut Training Center. An actual objective of providing remote access in the course of training session using video conferencing, electronic manuals and other assets as well as remote working with software of functional-modeling stands is discussed. The existing groundwork for work in this line, sugges-tions on the content of the training complex with the allocation of unified classrooms, virtual computer complex, and the data transfer system in overall structure are also given here.

Choice of technologies of ensuring exploitation suitability of buildings in the underground construction area

Introduction. One of the serious problems in the construction of underground structures in a dense urban area is the occurrence of excess deformations of the foundations of operating buildings that fall into the zone of influence of underground construction. The subject of the study was the calculated justification of the modern technology of compensatory injection. The relevance of the task is determined by the fact that the choice of the most effective protection technology should be based not only on a comparison of technological precipitation with maximum permissible values, but also on the assessment of the possibility of monitoring and controlling the movements of the foundations of buildings and structures during construction and subsequent operation. The purpose of the study was to compare various methods of protecting the foundations of existing buildings and structures and justify the selection of the most effective of them for further implementation and dissemination in the design and construction of urban underground structures. Materials and methods. On the basis of the survey data of the operated building falling into the impact zone of excavation of the pit for the construction of the installation and shield chamber of the subway, the parameters of the stress-strain state of its foundations are studied by mathematical modeling. The problem was solved by the finite element method based on the software and computer complex Z_Soil v.18.24. Results. Based on the analysis of the results of the examination of the administrative building using the finite element method, a change in the parameters of the stress-strain state of the foundations was modeled with various technologies for strengthening it. In the course of solving the geotechnical problem, it was found that the minimum impact on the foundations of the building during the construction of the pit was obtained in the method of compensatory injection. The system of criteria for making a decision on choosing an effective way to ensure the suitability of buildings in the underground construction zone for operation is substantiated. Conclusions. The results of this work can be used to justify the choice of technology for prevention and control of excess deformations of foundations. The function for calculating the volume of injected material in the Z_Soil software and computer complex can be used to justify the consumption of materials and the economic efficiency of the technological solution.

Calculation of dynamic characteristics of a television tower

The paper considers the calculation of dynamic characteristics of a television tower exposed to wind pulsation. During the investigation, the tower outline shape was changed, as well as the material of the structure, then it was subjected to the wind load using the SCAD ++ computer complex.

The peculiarities of using the computer complex HC-psychotests in the process of psychodiagnosis of the level of development of future specialists’ mental capacity

The IT revolution, which has embraced material production, social relations and the whole sphere of culture and education, is more and more contributing to solving the problem of automation of intellectual processes in science, technology and society, as well. This scientific article is devoted to the consideration of topical issues of introduction of the computer complex HC-psychotests in the process of psychological support of professional-personal development of the future specialist during the period of study in high school. The article also presents the analysis of the versatile possibilities of using the NSpsychotest in the paradigm of modern education. In this scientific article, the results of the screening study with the use of HC-psychotest in the process of psychodiagnosis of the level of development of mental capacity of future specialists are analyzed in detail. It is determined that the complex HC-psychotests allowed to give multilevel, multiparametric characteristics of the mental states of the respondents with the use of psychological, psychophysiological, physiological and social indicators. It has been proved that the introduction of computer psychodiagnostics has not only enriched the experimental base with appropriate methods that facilitate the implementation of various research strategies, but also combined empirical work into a single technological cycle.

Analysis of spatial state of multistory building with ceiling without beams

In this paper, we discuss a spatial work of construction structures under an influence of pulsating wind loads. There are examples of deformations those arise from incorrect arrangement of rigid structures. We consider the forms of oscillation of a frame building and show the result of their incorrect sequence. There are calculations in software and computer complex and their results are shown in the form of isofields of internal stress of enclosing structures. The results of calculations are compared with real deformations of structures. The work of a structure is considered on the example of an existing building.

Compliance of a rigid joint of a steel column of I-section on a rigid foundation

The article considers the compliance of a rigid assembly of a steel column of a typical I-section under the loads of an eccentric-compressive load with a random eccentricity. A simplified scheme of pinching a rigid hinge is considered as well as its detailed version in which the rigid part of the rod is elaborated as a basement, foundation plate, cross-arm and anchor bolts with plates. The authors carried out numerical studies of this site using a computer complex Abaqus 2017. Analysis of the results showed that the inclusion of compliance at a sufficiently accurate numerical simulation gives the same value for compressive forces. Thus, this node can be considered rigid, and the coefficient of buckling is almost equal to the theoretical value.
