The problem of redistribution of radio frequency used in the organization divisions
(Національний технічний університет "Харківський політехнічний інститут", 2021) Pashayev, Adalat Bakhtiyar; Sabziev, Elhan Nariman oglu; Hasanov, Arif Hasan oğlu
The problem of radio frequency distribution is considered in the article, taking into account the regulations and geographical location of the operating units. The problem of assigning radio frequencies from among those assigned for corporate use is studied. Using conformal mapping, it was substantiated that any territory can be divided into zones, each of which will have a border with only three other zones. In this case, in each zone, you can assign frequencies in the amount of one quarter of the total number of available frequencies that do not overlap with frequencies assigned to adjacent zones. A mathematical model of the problem of radio frequency redistribution has been built, taking into account the regulations and the geographical location of the units. The implementation of algorithm allows taking into account the history of frequency distribution by zones, which allows you to completely update the used radio frequencies for a new period of operation. A software module has been compiled that generates frequencies at random from those available for assigning corporate use for each zone. The software module allows fast and frequent reallocation of frequencies by zones, thereby ensuring the safety, reliability and stability of communication between organizational units.
Determining the location of an unmanned aerial vehicle based on video camera images
(Національний технічний університет "Харківський політехнічний інститут", 2021) Sabziev, Elhan Nariman oglu
The paper deals with the problem of determining the location of an unmanned aerial vehicle from video and photo images taken by surveillance cameras. As the observation area is considered to be sufficiently limited, the area under consideration can be taken as part of a plane. The solution to the problem is based on the construction of a bijective mapping between the known geographic coordinates of three different objects recognized in the images and their coordinates relative to the monitor plane. To this end, the geographical coordinates of the objects (latitude and longitude) are first converted to the Mercator projection, and a bijective mapping is built between the coordinates of the objects calculated in the Mercator projection and the coordinates relative to the camera monitor plane. Then, based on the current orientation angles of the unmanned aerial vehicle, the coordinates of the projection of its position on the monitor plane are calculated, and the geographical coordinates are found by applying the inverse of the constructed bijective mapping.
Modeling of observation in the mountain terrain depending on number of supervisory systems
(Національний технічний університет "Харківський політехнічний інститут", 2020) Bayramov, Azad Agalar oğlu; Sabziev, Elhan Nariman oglu; Nasibov, Yashar Ali оgly
The various types of electron-optical supervisory systems (SCS) have been used in the border stations of border zones in the Armed Forces of many countries. The mission of these SCS is to supervise the possible activities of smugglers, the illegal movement of enemy troops, the technics and weapon systems, the frontier intruders. In the paper, there has been offered a method which, on the basis of the developed mathematical model and Geography Information System technology, allows modeling of observation in mountain terrain depending on the number and location of SCS. The developed software module allows: 1) to generate the investigated terrain based on Digital Terrain Elevation Data file, 2) to input the possible observation points and the controlled zone via an interface,3) to simulate and visualize the observed areas for both single and group observation devices located in the possible observation points. The developed method had been applied toone of the selected terrains of the Azerbaijan Republic and demonstrated efficiency of the offered method. Based on the developed model and GIStechnology the visual modeling in mountain terrain depending on a number and a location of the SCS has been carried out.
Fuzzy diagnostics of soils according to the World Reference Base for Soil Resources
(Національний технічний університет "Харківський політехнічний інститут", 2020) Hasanova, S. A.; Pashayev, A. B.; Sabziev, E. N.
Soil classification remains one of the most controversial topics in the world soil science because of differences in the principles underlying it. As of today, many countries have developed and use their own national classifications. Since scientific classification facilitates successful investigation and proper use of soils, the issue arises of representation of one classification in another. In the paper the possibility of applying fuzzy technologies to soil diagnostics based on the World Reference Base for Soil Resources is considered. A trapezoidal form of membership functions of the parameter set of diagnostic horizons is proposed. The algorithm of fuzzy diagnostics is presented on the basis of the proposed functions. Conclusion. The paper proposes a fuzzi fication mechanism for the set of indicators of diagnostic parameters and describes the algorithm of the system of fuzzy inference about the identification of the values of the corresponding parameters in accordance with the compositional inference rule. Thus, the effectiveness of the use of fuzzy technologies in soil diagnostics by the World Reference Base for Soil Resources is demonstrated.
Modelling of the rationally deployment of observing systems
(Національний технічний університет "Харківський політехнічний інститут", 2019) Nasibov, Yashar Ali оgly; Bayramov, Azad Agalar oğlu; Sabziev, Elhan Nariman oglu; Hashimov, Elshan Giyas oğlu
The various types of electron-optical supervisory control systems (SCS) have been used in Armed Forces of many advanced countries. The mission of these SCS is to supervise day and night enemy troops, technics and weapon systems, frontier intruders with high precision a great and middle distance. The SCS optimal deployment in mountainous terrain makes possibility to use rationally SCS number, because SCS has very much costs. Using the rationally SCS number we can reduce a necessity of the specialist number. Also, it accelerates comander’s correct decision making. The optimal deployment of SCS on a terrain is one of important task of military reconnaissance. The specific character of such task is that the necessary for continuing surveillance and control military objects can be located in specific zones of terrain (for examples, in canyons, along of river etc.). Accessible places of SCS set are situated on some distance from these zones. The number of SCS is limited; therefore, it is impossible to distribute theirs on the all set points. It is necessary to select such SCS set points that the zone observation range would be the largest. In present paper the mathematical model of the rationally deployment of technical observing systems in mountainous terrain has been developed and offered. The determination method of visibility level between selected terrain points has been developed. The assesment criterion of rationally deployment and the algorithm of fast solution have been offered.
