Annotation:

The development of modern shortwave radio communication systems is largely focused on the use of cognitive radio technologies. Providing the functionality of systems built on the basis of these technologies involves the use of hardware complexes with automatic adaptive control. The practical implementation of such management is based on the use of a hardware and software complex based on an agent-based approach to the development of artificial intelligence systems. This approach makes it possible to ensure the use of effective adaptive communication methods in shortwave radio communication complexes based on taking into account the totality of a priori information about the propagation environment of radio waves, the signal-interference environment, the technical parameters of the radio equipment used and the rules for communication.

Annotation:

For a maneuverable aircraft (LA), the application of the method proposed by O.A. Tolpegin for approximating its reachable area at a given moment of time by a triangular shape, both in the vertical and horizontal planes of its flight, is considered. The relationship between the coordinates of the vertices of the triangular reachable area (TRA) of the aircraft and such given initial data as the moment of time of approximation of the aircraft’s motion, the magnitude of its velocity module, the initial angle of inclination of the trajectory (or course for the horizontal plane), and others is shown. Algebraic expressions for regression functions are proposed, according to which the coordinates of the vertices of the triangular reachable area of the aircraft are calculated. It is proposed to use regression functions to accelerate the calculation of the coordinates of the vertices of the triangular reachable area of the aircraft, the coefficients of which are calculated based on the factor analysis method.

Annotation:

The paper considers approaches to improving methods for data acquisition and analysis in the interests of a space situational awareness system for hazardous event prevention (ASPOS) in near-Earth space, focusing on the integrity of space objects. Particular attention is given to the processing and standardization of time-domain radar cross-section (RCS) signatures of space objects, as well as to the evaluation of an integral similarity metric for radio signal time series. Based on this metric, an approach is proposed to optimize decision-making regarding the integrity violation of a space object and to identify regions of increased monitoring priority, thereby enhancing the overall effectiveness of the ASPOS system.

Annotation:

Fixed communication nodes operate under the conditions of mutual influence of two key factors — structural reliability and performance. The article offers an indicator of the efficiency of such a node: the availability coefficient, which, unlike classical metrics, takes into account not only parametric (failure rate, recovery time), but also structural properties (redundancy, topology of connections). The final model is obtained by complex integration of two submodels: the first describes the behavior of the system with limitations in terms of reliability, the second with performance limitations. This approach allows for a more adequate reflection of transitional and steady-state operating modes. The proposed availability coefficient makes it possible to quantify how structural redundancy compensates for reduced productivity and vice versa.

Annotation:

This article explores the development of a robot swarm control system based on the use of a control digital twin. The paper clarifies several definitions and the concept of a control digital twin, proposes a model for a control digital twin of a robot swarm, and further refines it for building a control system for a swarm of unmanned aerial vehicles and ground robots performing the common task of searching for and extinguishing fires. The use of the presented control digital twin model enables the utilization of all the advantages of multi-agent systems and decentralized control without requiring the need to organize interactions within a heterogeneous robot swarm. Implementing the approach discussed in this article simplifies the robot control system itself, limiting its tasks to autonomous control of its own actions.

Annotation:

The paper presents a methodology for optimizing the frequency-hopping spread spectrum (FHSS) algorithm for a radio communication network operating in an anisotropic propagation environment under intentional interference. The methodology comprises six stages: frequency band state analysis, receiver decision rule optimization based on introducing an indifference region, potentially optimal plan formation using an iterative mixed strategy optimization procedure, transition moment determination, unconditional group plan formation, and FHSS key generation. Numerical simulation results demonstrate a gain of up to 6,2 dB compared to uniform frequency distribution.

Annotation:

The paper presents a methodology for dynamically distributing emergency response forces among damaged facilities. The methodology combines vector-based prioritization of facilities, which takes into account the differences in the functional tasks of fire and rescue units, emergency response teams, engineering, technical, and utility services, with a dynamic model of work completion time. A system of factors is proposed to generate independent priority vectors, an organizational prioritization coefficient is introduced, and a nonlinear production function with diminishing returns is used. A criterion for the appropriateness of force distribution is developed based on reducing the total work time. The methodology provides a reasonable approach to managing emergency response forces in a changing environment.

Annotation:

In this article, the deformations and destruction of the material of a multilayer ceramic composite armor plate during a ballistic impact of a 9-mm bullet on it are studied. The relevance of the research is the method of constructing a geometric model of ceramic composite armor and the physical properties of its material based on fundamental know­ledge about deformation, taking into account thermal processes, as well as using numerical integration of partial differential equations, which are currently being implemented in validation with experimental studies using the method of reverse identification. The procedure for modeling the ballistic impact of a bullet into a ceramic composite armor plate using the FEM Finite Element Method is considered, which makes it possible to describe the separation of a material during its destruction by comparing experimental studies.

Annotation:

The article is devoted to substantiating the need for all interested parties to study the hygienic aspects of the safety of military service. At the end of the 20th century, the Russian army and Navy developed and implemented the Military Service Safety management system, which was credited with success in protecting the life and health of military personnel. However, it soon became clear that the results achieved did not fully meet the expectations: the number of dead and injured soldiers still remains tall. One of the reasons for this dissonance lies in the imperfection of military personnel training, in particular, it concerns the mandatory study of hygienic safety issues, without knowledge of which it is difficult to achieve the desired result.
