Összefoglalás. Az egyes országok államigazgatásában sajátos
funkcióval rendelkező nemzetbiztonsági szolgálatok fontos szerepet töltenek be a
biztonság fenntartásában, a politikai színtéren megszülető döntések
információkkal történő támogatásában. Mindez képzett, a biztonságpolitikai és
technológiai környezet dinamikus változásait értelmezni és értékelni tudó, a
nemzetbiztonsági területen is korszerű ismeretekkel és megfelelő kompetenciákkal
rendelkező állományt igényel, amely képzési folyamatában egyre fontosabb szerep
hárul a felsőoktatási környezetre. Jelen tanulmány, nemzetközi példák alapján,
modelleket felállítva, az egyre inkább felértékelődő nemzetbiztonsági képzési
kapcsolatok felsőoktatásban való sajátosságait vizsgálja. Módszerként a
témakörben elérhető egyes nemzetközi intézményi és képzési rangsorok, valamint
az intézményekről elérhető szakirodalmi források vizsgálata jelent meg.
Summary. National security services, which have a specific role in
the administration of the countries, play important role in providing security
and supporting decisions in the political arena by information. This requires
trained personnel with up-to-date knowledge and competencies in the field of
national security, capable of understanding and assessing the dynamic changes in
the security and technological environment. In this process, the higher
education environment has increasingly important role. Concerning the
security-oriented higher education courses, it is difficult to determine whether
these can be considered as a form of “national security” higher education or
merely as an educational field of defense sphere. Apart from the sectoral
specificities, the main difficulty in making a comparison are the extreme
diversity in the interpretation of security and its interdisciplinary links. In
addition to trainings in the fields of intelligence studies and national
security studies, international security, security policy, the military elements
of security, and even the technical and cyberspace-related elements of
intelligence training, all provide valuable knowledge for the sector. However,
the international institutional examples of higher education in the field of
national security may be worth examining, as they essentially create a link
between the innovative knowledge of the academic world, which is the center of
knowledge, and the closed security sector, which is open to relevant knowledge.
In line with these ideas, the present paper explores the specificities of the
increasingly valorized national security training links in higher education by
setting up models based on selected international examples. The used methodology
is the examination of the international rankings of training programs available
on the subject, as well as of the literature available on institutions.

This paper reports an analysis of the frequencies and shapes of oscillations of the tank with a volume of 3000 m3 with a winding of high-strength steel wire with a diameter of 3 mm, 4 mm, and 5 mm, applied in increments of 1:3. In addition, for the tension force of the turn in the range from 0.2 to 0.8 of the yield strength of the wire material. The study was carried out on the basis of a finite-element method in the ANSYS software package for a three-dimensional geometric model of the structure. At the same time, the software took into consideration the height-uneven width of the cylindrical wall taking into account the height of the filling to the maximum height and the tension forces of the winding.
It has been established that a change in the diameter of the winding wire does not lead to a significant change in the spectrum for the first ten significant frequencies. And an increase in the tension force of the wire in the winding leads to a decrease in the magnitude of oscillation frequencies. The exception is the sixth frequency. Its values are equal to one-tenth of a Hz for all estimated cases of the force of tension of the turn in the range from 0.2 to 0.8 of the yield strength of the wire material. The oscillation shapes of the tank reinforced by the winding have been determined. The change in the tension force of the wire in the winding does not change the number of waves at the circumferential coordinate at the free edge of the structure. We studied the loss of stability of the tank wall under distributed internal pressure. A comparative analysis of the sixth oscillation shape and the shape of stability loss reveals that they have the same number of waves at the circumferential coordinate.
The results reported here could make it possible to effectively use the pre-stress in order to detune the tank from the resonant frequency when operating in seismically hazardous areas
Identification of the pulse axisymmetric load acting on a composite cylindrical shell, inhomogeneous in length, made of different materials

Published: November 2022

The problem of identifying the load acting on the elements of structures belongs to the class of inverse problems of the mechanics of a deformable solid, which are often incorrect. Solving such problems is associated with the instability of the calculation results, which requires the development of special methods for their research. This predetermines the relevance of this study.
The object of the study is a single-pass cylindrical shell consisting of two rigidly fastened butt-fastened sections made of different materials. Each of the shells is assumed to be elastic isotropic, having a cross-section of medium thickness. The equations of axisymmetric deformation of shells are used within the framework of Timoshenko hypotheses.
An approach to solving direct and inverse problems for such discretely heterogeneous objects is proposed, which implies the conditional separation of a discretely heterogeneous cylindrical shell along the length, followed by the addition of functions of fictitious loads. The main analytical relationships for building a system of integral Volterra equations are given, for which an analytic-numerical solution is derived.
The final ratios have been obtained, which make it possible to calculate the kinematic and force parameters of the study object in the process of non-stationary deformation. The inverse problem of identifying arbitrary loads acting on a shell that is heterogeneous in length is solved in a general form. An algorithm for the restoration of pulse loads has been developed, which is robust to errors in the initial data (about 5 %).
The material related to solving direct and inverse problems for shells that are discretely heterogeneous in length can significantly advance the methodology for identifying pulse loads acting on structural elements

The object of this study is the process of segmentation of images acquired from space optoelectronic surveillance systems. The method to segment images from space optoelectronic surveillance systems based on the Sine-Cosine algorithm involves determining the threshold level; unlike the known ones, the following is carried out in it:
– preliminary selection of red-green-blue color space brightness channels in the original image;
– calculation of the maximum distance of movement of agents in the image in each brightness channel;
– calculation of the values that determine the movement of agents in the image in each brightness channel;
– determining the position of agents in the image using trigonometric functions of the sine and cosine in each brightness channel.
An experimental study into segmenting images acquired from space optoelectronic surveillance systems based on the Sine-Cosine algorithm was carried out. It was found that the improved method of image segmentation based on the Sine-Cosine algorithm makes it possible to segment the images. In this case, objects of interest, snow-covered objects of interest, background objects, and undefined areas of the image (anomalous areas) are identified.
The quality of image segmentation was assessed using the Sine-Cosine algorithm-based method. It was found that the improved segmentation method based on the Sine-Cosine algorithm reduces the segmentation error of the first kind by an average of 21 % and the segmentation error of the first kind by an average of 17 %.
Methods of image segmentation can be implemented in software and hardware systems that process images acquired from space optoelectronic surveillance systems.
Further studies may involve comparing the quality of segmentation by the method based on the Sine-Cosine algorithm with segmentation methods based on evolutionary algorithms (for example, genetic ones).

The object of the research is a special-purpose communication system. The relevance of the research lies in the need for complex management of resources of special-purpose communication systems. The resources of the special-purpose communication system are defined as: spatial, temporal, frequency and hardware resources. Destabilizing factors include: intentional interference; denial-of-service cyber attacks and fire damage to individual elements of the special-purpose communication system. The method of complex management of resources of special-purpose communication systems was improved. The difference between the proposed method and the known ones is that the specified method contains improved procedures:
‒ determination of the impact of destabilizing factors on the special-purpose communication system;
‒ description of special-purpose communication systems of various architectures;
‒ determination of the rational route of information transmission and operation mode of communication devices in the general special-purpose communication system;
‒ consideration of uncertainty about the state of the special-purpose communication system;
‒ determination of the number of necessary forces and means of communication, which must be increased for the full functioning of the special communication system. The improved method provides a gain of 20‒26 % compared to classical approaches to the management of resources of special-purpose communication systems. The improved method can be used at the control points of the communication system of groups of troops (forces) while planning the organization of communication and at the stage of operational management of the communication system.

A finite-element model for the heat engineering calculation of fireproof reinforced concrete slab has been built, which is designed to assess the fire resistance of unprotected reinforced concrete structures. A feature of the model is the correct choice of types of heat transfer in the cavities of reinforced concrete ceilings. An algorithm that includes experimental and calculation procedures in determining the fire resistance of unprotected reinforced concrete structures has been applied. The initial, boundary conditions for the construction of the model were formulated; the thermophysical properties of materials were substantiated. Thermal calculation of fireproof multi-hollow reinforced concrete ceiling under conditions of fire was carried out. The adequacy of the developed finite-element model was checked. A satisfactory convergence of experimental and calculated temperatures with an accuracy of 10 % was established, which would suffice for the engineering calculations.
The model built makes it possible to assess the fire resistance of unprotected reinforced concrete structures. Thus, there is reason to argue that the model constructed can partially or completely replace the experimental assessment of fire resistance, provided that the construction and setting of the model parameters are correct

Fossil fuels are non-renewable, finite, and exhausting. Therefore, it is necessary to find alternative sources of energy. Solar energy is abundant in nature, so it can be considered as the best alternative to meet the energy demand. It is sustainable, renewable, and scalable. Increasing the efficiency of harnessing solar energy should be one of our top concerns because it is a renewable resource. The challenge in utilizing this energy is to increase efficiency as well as reduce production costs. So, a dual-axis solar tracker was developed in this study to ensure that the tracked solar cells create more electrical energy than stationary solar cells, improving the performance of the solar panels and expanding their ability to make the most of the solar radiation. The experiment yielded great results. Due to its constant exposure to sunlight, the temperature of the mobile cell is higher than that of the stationary cell. The radiation intensity of the tracked cell is more than that of the fixed cell. The radiation intensity for the traced cell is more than that of the fixed cell and peaks at 1282 W/m2 on September 10 and 1028 W/m3 on September 11. For day 10, there was a daily rate of rise in radiation intensity on the tracker cell of 42 % compared to the fixed. Day 11 saw a difference of 210 W/m2/h, or 61 percent. The results are almost same from midday until dusk. During the day, the tension in the vacuum is somewhat different for stationary cells and tracking cells, with the value of the tracker being marginally lower than the fixed value. The increased temperature in the cell caused by more solar radiation and a warmer environment is thought to be the reason for the lower energy gain in the tracker
