The analysis of the impact of ultrashort electromagnetic pulses on the data transmission channels of computers included in the control system of modern unmanned aerial vehicles has been performed. It is shown that when developing a model of the impact of ultrashort electromagnetic pulses on data transmission and control channels, it is possible to use the results of an analysis of the impact of electromagnetic pulses on elements of local networks.
Keywords: unmanned aerial vehicle, onboard control system, local area network.

The paper considers a model for assessing the sustainability of big data storage in distributed storage based on the HDFS file system. The model makes it possible to evaluate the stability of data storage depending on the parameters of HDFS construction. Experiments have confirmed the effectiveness of the proposed model and the approach based on it to provide the required stability of data storage.
Keywords: big data, distributed storage system, HDFS.

The paper propose a cognitive model of information system users, which contains a full range of psychophysiological parameters and limitations of operators-users of information systems of law enforcement agencies, as well as environmental factors that have a direct impact on the working conditions of specialists. The model makes it possible to take into account these factors at the stage of designing graphical user interfaces of information systems. In the context of constant modification of existing information systems and the emergence of new information systems and technologies, this approach to the design of man-machine interface will allow the end user to minimize the path from the initial introduction to the product to solve his problems, increase his comfort and work efficiency.
Keywords: cognitive model, man-machine interface, information system.
