At present, the practice of supporting many types of human activities requires the use of the spatial data infrastructure. Such an infrastructure integrates spatio-temporal sets from many sources of information within itself, providing the user with various types of processing, analysis and visualization methods. This article describes the architecture of the software system and the processes for managing sets of spatio-temporal data to solve agricultural problems. Measurement data using multispectral satellite systems, unmanned aerial vehicles (UAVs), as well as a priori information (meteorology, agrochemical information, etc.) are taken as input information. The User of the Software System is provided with the opportunity to control the spatial information of the territory of agricultural fields, sets of temporal data from various spatial data. An important achievement of the work is the combination of the results of satellite and UAV images according to the controlled parameters, that makes possible to expand the area of use of UAVs and verify them. The results of real data processing are presented.

The article is devoted to the analysis of the challenges that characterize the transformation of threats to the national security of the state. The types of stochastic threats to the country's security associated with globalization, information and transport accessibility, labor and educational migration are determined. Examples of occurrence of stochastic processes with predictable consequences are considered. Problems in the creation of research tools and services are identified.

The ways to reduce losses of electrical energy in power supply systems of industrial enterprises containing powerful semiconductor converters and asynchronous motors are considered. The source of additional electric power losses related to subharmonic nature of voltage fluctuations from operation of converters using the principle of frequency-pulse control is determined. The operation algorithm for thyristor switches of semiconductor converters is proposed, that provides reduction of electric power losses in asynchronous motors connected in parallel with powerful converters. The voltage graphs and currents of simulation model in operation modes of converters show the potential to increase energy efficiency of operation of a wide range of industrial objects with asynchronous motors, connected in parallel and having cyclically changing load.

Steganography allows to ensure the confidentiality of information by organizing covert data transmission channels. However, the effectiveness of steganographic information protection directly depends on the invisibility of a secret message, both for the human eye and for steganalysis methods. The paper proposes an approach that allows solving the problem of vulnerability of the popular QIM embedding method to statistical steganalysis. For this, it is proposed to use a variable quantization step, which is adaptively selected for each block of the JPEG cover image. The experimental results demonstrate an increase in the security level of steganographic embedding due to the application of the proposed approach.

The systems intended for detecting objects of artificial and natural origin are widely used while implementing the remote sensing methods. In this case, such different frequency ranges of sounding signals as radar, acoustic and optical ones are used. This article presents the results of patent analysis of the detection systems for such groups of the International Patent Classification as G01S13, G01S15, G01S17. The analysis has been carried out using the database of the United States Patent and Trademark Office (USPTO) inventions registered from 2015 to 2019. The aim of the given study was to compare the development trends of the object detection systems using the reflection or reradiation of radio-, acoustic or electromagnetic waves. It is shown that the proposed approach makes it possible to identify the promising (breakthrough) technological directions, as well as to form predictive estimates of their development in the short-term.

The article discusses the problem of infringement of academic ethics among students of universities. The author compares the perception of this problem by scientists, university administration, teachers and students. The prospects of applying punitive measures to counteract fraud, measures aimed at correcting the corporate culture of the university, as well as measures to reorganize independent work that makes attempts at plagiarism impossible or unprofitable are evaluated. Based on the application of the change formula, or the Glaicher's formula, the differences between the characteristics of students who choose a cheating strategy in training and students who prefer honest work and cooperation are revealed. The first steps aimed at changing the behavior of dishonest students and involving them in the cooperation strategy are proposed.

A model of a transport connection controlled by a transport protocol with the technology of forward error correction in the selective failure mode in the form of a discrete-time Markov chain is proposed. The model takes into account the influence of the protocol parameters, the level of errors in the communication channels, the round-trip delay and the technological parameters of forward error correction on the throughput of the transport connection. The analysis of the dependence of the advantages of the transport protocol with forward error correction over the classical transport protocol is carried out.
