The article is devoted to the consideration of the problems of didactic design of teaching materials by a teacher of disciplines of the humanities and socio-economic cycle associated with the study ...of a significant amount of information from various sources, the need to select a number of literary sources taking into account their specifics for different educational tasks and types of educational activities, as well as ranking the most important didactic units for the formation of working programs of disciplines. The possibilities of using automation tools for the analysis of text materials are revealed, which will allow a teacher engaged in the didactic design of a particular discipline to conduct a syntactic analysis of methodological materials, significantly reduce the complexity of this process when developing, making changes and adapting courses of social and humanitarian orientation. As a result of the analysis of the subject area, the authors determined a list of functional requirements, based on which the results of the physical and logical design of the system were presented, including a database model, system architecture, as well as a deployment diagram using an object-oriented modeling language.
Data of the International Bank of Digital Information on the time distribution of the virtual dipole moment (VDM), supplemented by data of more recent studies (a total of 5645 values), were used as ...the basis for analyzing the distribution of VDM values for Earth’s history using the concept of the Earth’s magnetic dipole field. The VDM behavior is characterized by a positive linear trend from 4.2 × 10

wavelength from 220 to 920 Ma. The average wavelength of such undulations is estimated at 570 Ma, which in order of magnitude approaches the period of the Wilson cycle. It has been revealed for the first time that the magnitudes of magnetic field undulations over time are oscillatory in nature and increase toward present day.

In conditions of economic development and the formation of new economic ties, the uninterrupted operation of transport and its condition significantly affect the level of economic security of the ...state. The abstract service "transport" is considered by the authors as a complexly structured economic category consisting of three levels. At the first level, a transport service is defined as a form of good; at the second level - as a form of activity; at the third level, in accordance with the social nature of the reproduction of services, a transport service is an economic relation. The article formulates the tasks of ensuring economic security in the provision of transport services and its main components. It is proved that reliable economic security at all territorial levels is possible provided that business entities are stable in the provision of transport services, as their potential is a determining stabilizing factor in anti-crisis development, a guarantee of economic growth and maintaining the country's economic independence and security. In organizing and managing the transport component of economic security, it is necessary to coordinate the principles of protecting the transport component of security with the interests of the state to ensure economic security in all sectors of the economy, to determine threshold values for indicators and threats to transport security in order to solve the problems of eliminating these threats.
The paper analyzes the bottom stereoscopic imaging based on the interferometric side-scan sonar data, which provides for the more efficient identification of the bottom structures owing to the ...perception’s extensionality relative to the three-dimensional models. The stereopair construction enabling the three-dimensional perception of the formed images is discussed.
A new map of the axes of linear magnetic anomalies for eastern regions of the Eurasian Basin has been compiled. Based on the results of Russian geomagnetic surveys, paleoanomaly C25 was distinguished ...here for the first time, and the transition from rifting to spreading has been dated to the chron interval of С25r–С26n (57.656–59.237 Ma ago). The axis of the zone of splitting of marginal continental fragments of the Lomonosov Ridge from the Siberian shelf has been reconstructed. The Euler poles and angles of rotation that describe the splitting kinematics have been determined for the first time, as well as noncoincidence of conjugate isobaths related to sliding of peripheral continental crust areas along the lithospheric thrust plane.
The Lincoln Sea floor evolved during stretching of a segment of the continental Greenland –Barents Sea shelf. Prior to the onset of extension, the continental shallow-water Morris Jesup Rise and the ...Yermak Plateau were a single unit. During rifting, this single continental plateau broke apart, initiating propagation of the Gakkel mid-ocean ridge toward the Atlantic. The breakup continued for ~1.5 Ma, 35.3–33.7 Ma ago. The emplacement of numerous mafic dikes during rifting could have caused the high-amplitude magnetic anomalies on the single plateau. For the first time, the fracture geometry involved in the breakup of the continental crust has been reconstructed, the Euler poles and angle of rotation describing its kinematics have been determined, and the paleobathymetry on the flanks of the fracture have been reconstructed.
