Abstract:

One of the ways to improve the adaptation equipment used in decameter radio lines for military purposes is the use of multi - stage adaptation. An integral component of such an "intelligent system" will be an adaptive forecasting system, which will make it possible to predict the development of an interference situation for a timely response of a multiparametric adaptive system to changing communication conditions. The materials presented in the article allow solving the problem of adaptive prediction of interference levels in the decameter range based on a priori data obtained during statistical analysis of the radio frequency spectrum load, and the problem of multiparametric adaptation based on changes in several parameters of the radio signal.

Abstract:

Modern communication networks are built on technical means using digital data processing. Digitization and informatization of telecommunication systems allows the formation of many virtual communication networks based on the resources of one physical network. The resources of the physical communication network are limited, so the operation of many virtual networks on its basis will inevitably lead to conflict situations. Users of a virtual communication network, especially corporate management systems, can work effectively only when it operates with the specified requirements. These circumstances necessitate the solution of the problem of increasing the stability of the functioning of virtual communication networks operating on the resources of one physical network. At the same time, in the process of routing data in a virtual network, it is necessary to take into account all categories of resources of the physical communication network.

Abstract:

The rapid development of communication systems leads to a high load of radio frequency ranges with signals from an ever - growing number of radio electronic means using spectrally efficient signal - code structures. In this regard, the national radiomonitoring system implements a set of measures aimed at observing the discipline and regulations of radio communication by users of communication systems, through automated radiomonitoring of radio signals from radio electronic equipment. Within the framework of this activity, recognition of the type of modulation of radio signals is of particular importance. The proposed approach is based on the idea of imaging radio signals characterized by many different modulation parameters in the form of images in the parameter space of phase diagrams. The article proposes the main stages of the methodology for recognizing the type of continuous phase modulation radio signals in radiomonitoring systems.

Abstract:

The choice of the optimal mode of operation for radio transmission facilities in a radio link is an important task in terms of ensuring the necessary quality and reliability of communication. The choice of the operating mode can be carried out on the basis of various criteria, however, it is obvious that the more criteria on the basis of which the choice is made, the more accurate the choice. The article discusses a variant of implementation in a small - sized tropospheric communication station of a «operating mode controller» (OMC) device, which provides the choice of an operating mode depending on the change in the state of the communication channel. It is known that changes in the state of the tropospheric communication channel are of a random nature, therefore, the criteria based on which the choice of the operating mode in the OMC is made are the values of the current signal - tonoise ratio and the probability of erroneous reception.

Abstract:

The transition from a single use of robotic sistem for military purposes to a group one gives rise to a number of problems, such as the need for simultaneous control of individual objects and the group as a whole, as well as ensuring interaction between groups. This, in turn, raises the level of requirements for information security of communication between network nodes. It is required that each node is authorized when added to the network, and the network provides forward and backward secrecy. In addition, an increase in the complexity of the applied algorithms for protection and network organization should not cause inertia in object management. To solve the listed problems, the work considers the developed method for the distribution of key information applicable to the groups of robotic sistem for military purposes.

Abstract:

The article presents a multilevel logical - probabilistic model for assessing the stability of a special - purpose communication center, its subsystems (elements) exposed to a complex of destabilizing factors of various nature. The scientific task of the research was based on the idea of developing a model of an elementary technical object with the property of stability, the aggregation of the structure of which, taking into account the nesting of subsystems and elements of the communication node, as well as the known functional and logical conditionality between them, made it possible to unify the development process of structurally complex arbitrary level and organization. The efficiency of the models, the sensitivity to changes in the initial data and the consistency of the results obtained with their help have been proved.

Abstract:

The article presents methodological principles for assessing the stability of nuclear and radiation - hazardous facilities to the impact of eventual threats. An approach to assessing the stability of objects to the impact of eventual threats is defined based on the calculation of the stability indicators of functional objects. As an indicator of the stability of functional objects, it is proposed to consider the potential for the implementation of threats, reflecting the functional dependence between the probability of the implementation of the threat and the damage from the implementation of this threat - the time required for the restoration of the nuclear power plant (elimination of consequences) after the implementation of the threat. To assess the level of integrated security (the resistance of the NAR as a whole to the impact of the entire spectrum of threats), approaches to aggregation (convolution) of the values of stability indicators at all levels of the hierarchical structure have been developed. The criteria for the level of stability of objects are defined. The described methodological approach allows us to successfully solve the tasks of assessing what has been achieved, monitoring the current and predicting the possible level of stability of functional objects under the influence of threats.

Abstract:

The paper considers the solution of the multicriteria problem of finding the vector of the most probable control strategies for a mixed group of unmanned aerial vehicles (UAV) in the conditions of its implementation of diverse tasks. The solution is based on the use of the hierarchy analysis method, which allows you to interactively find such a variant (alternative) that best matches the understanding of the essence of the problem and the requirements for its solution. The constructed logical decision - making model (LDMM) takes into account the full vector of possible unfavorable factors (threats) acting on the complex with UAVs and the peculiarities of using a group of UAVs in real conditions. The developed LDMM will allow the control center of the UAV group, located on board the leading UAV, to promptly make decisions on the rational distribution of available resources for solving diverse tasks for their intended purpose.

Abstract:

Distributed corporate management systems are forced to use the resources and services provided by cyberspace for their functioning. Integration into cyberspace makes management systems the target of constant attacks by both single hackers and cyberterrorists, as well as organized hacker communities. Information and technical impacts on management systems lead to a decrease in the quality and quantity of services provided by elements of the corporate management system, transfers them to non - standard modes of operation, and in extreme cases leads to a complete shutdown. The final result of the impacts is the disruption of management carried out by the corporate management system. The article considers the method of reconfiguration of the communication network, taking into account the assessment of the awareness of the source of information and technical impacts carried out through cyberspace. The proposed method makes it possible to ensure the functioning of the communication network in the conditions of information and technical impacts, taking into account the assessment of the awareness of the source of information and technical impacts about the structure of the communication network.

Abstract:

The effectiveness of shooting depends not only on the perfection of the weapon and ammunition for it, but also on the recoil of the small arms, which the shooter perceives. Therefore, the study of the retarded recoil of weapons in the «shooter - weapon» system is of practical interest. Based on the study of recoil video stills when firing from various types of small arms, a computational model of the «shooter - weapon» system is proposed for shooting from prone, sitting and standing positions. With the use of the proposed model, theoretical studies of inhibited recoil when firing from the indicated positions have been carried out, which made it possible to calculate the change in speed, momentum and power in the process of inhibited recoil. The proposed solutions make it possible, already at the stage of preliminary study, to evaluate the recoil parameters and their changes for various combinations of the main characteristics of the «shooter - weapon» system.

Abstract:

The article discusses the question of the characteristics of the shell materials used in the calculations of the functioning of small arms with the recoil of a free (semi - free) bolt. The experimental data obtained made it possible to conclude that the material of the liner in the process of firing changes its properties towards an increase in plasticity with a simultaneous decrease in strength. The change in characteristics is associated with the process of deformation of the sleeve, accompanied by significant heating, both convective and dissipative. On the basis of a complex of experimental and computational work, the characteristics of the liner material were determined, which made it possible to agree the computational and experimental data.

The article considers the first attempt to create an aircraft carrier of bomb and missile weapons in Russia on the initiative of the German inventor F. Leppich. The author states the ability of Russia at that historical time to quickly deploy and well finance very hightech works for the XIX century, which are of great state importance. The reasons for the unsuccessful completion of this project for Russia are analyzed. The system regularities of such a result are called, among which the neglect of the science possibilities and the involvement of persons with insufficient qualifications for solving important state tasks is particularly instructive for the present time. The signs of a special operation carried out by France against Russia with the help of this project, which caused great harm to the country, are revealed.

Abstract:

Evaporated gas generation, venting and flaring (BOG) is considered one of the contributors to greenhouse gas emissions (GHG). Existing models are unable to analyze the actual behavior of vapors inside a liquefied natural gas (LNG) tank. In this paper, an evaporation model is used to estimate the LNG evaporation rate (BOR) inside an LNG tank. The result shows that the BOR value is consistent with previous research using a different model and with the International Maritime Organization (IMO) standard of less than 0,15 % weight per day. The results also allow us to visualize the vaporization behavior of LNG in tanks.
