Published: December 2023

Objectives. Radio-technical information transmission systems are widely used in various sectors of our life, not only for telecommunications and associated domestic needs, but also for the functioning of various special services, such as emergency response units, which increasingly use robotic complexes in the course of their work. In the event of an emergency, robot devices can be used to get in under rubble, in concrete pipes or other municipal facilities, which typically result in a sharp deterioration of the necessary conditions for the propagation of radio waves. In this regard, the problem of ensuring reliable communication with the robotic complex becomes rather acute. The aim of the present work is to reduce the effect of multipath propagation of radio waves in the communication channel under complex interference conditions.Methods. The methods of statistical radio engineering and mathematical modeling are used according to optimal signal reception theory.Results. The presented model for a multi-element, spatially-distributed, in-phase receiving antenna of various configurations, featuring an electronically adjustable radiation pattern, is designed to ameliorate the multipath nature of signal propagation. A simulation of a multipath communication channel was carried out in the presence of one main and three reflected beams of radio wave propagation, as well as with harmonic interference at two angles of its arrival and different frequency detuning relative to the frequency of the useful signal. The probability of a bit error when receiving discrete information using the proposed antenna is estimated.Conclusions. The proposed signal processing algorithm on the receiving side can be used to partially compensate for the influence of the multipath effect. As a result, the noise immunity of information reception in comparison with reception on an omnidirectional antenna with one antenna element increases: for a bit error probability of 10−3, the energy gain ranges from 2 dB for two beams to 7–10 dB for three or four beams. In the presence of concentrated harmonic interference in the radio channel, its simultaneous spatial (by the antenna) and spectral (by the demodulator) filtering is also observed, the effectiveness of which depends on the direction of arrival and the frequency detuning of the interference, which also leads to a significant decrease in the error probability.
Properties of the Wrońskian determinant of a system of solutions to a linear homogeneous equation: The case when the number of solutions is less than the order of the equation
Authors: Khrychev D. A. 
Published: December 2023

Objectives. The work sets out to study the properties of the Wrońskian determinant of the system of solutions to a linear homogeneous equation in cases when the number of solutions is less than the order of the equation, comparing them with the known properties of the same determinant when the number of solutions is equal to the order of the equation.Methods. The work uses the methods of linear algebra according to the theory of ordinary differential equations, as well as mathematical and complex analysis.Results. It is shown that the vanishing of a considered determinant on an arbitrarily small interval implies its vanishing on the entire domain of definition; the solutions turn out to be linearly dependent. A stronger result is obtained in three cases: (1) if the coefficients of the equation are analytic functions; (2) if the number of solutions is equal to one; (3) if the number of solutions is one less than the order of the equation. Namely, if the set of zeros of the considered Wrońskian has a limit point belonging to the domain of definition of solutions, then the determinant is identically equal to zero and the solutions are linearly dependent.Conclusions. According to the obtained results, the Wrońskian of a system of solutions of a linear homogeneous equation can serve as an indicator of the linear dependence or independence of this system in cases where the number of solutions is lower than the order of the equation; here, the solutions are linearly dependent if and only if their Wrońskian is identically equal to zero. In this case, there is no need to check whether the determinant vanishes over the entire domain of definition, since it is sufficient to do this on an arbitrarily chosen interval or even (in the special cases listed above) on an arbitrarily chosen set having a limit point.

Published: December 2023

Objectives. Snow cover has a complex multifactorial impact on the environment as a link between global climatic processes and the system of the Earth’s surface. Snow cover monitoring is one of the key tasks of hydrometeorology which also requires the systematic regular collection of its indicators. This work aims to develop an architecture of geoinformation technology for snow cover monitoring with the purpose of addressing the problem of automating the collection of snow cover indicators and their further maintenance. This architecture can also be used for other hydrometeorological monitoring tasks.Methods. This paper analyzes the existing fundamental basis of snow cover data collection and uses the method of systems approach to describe the architecture of distributed geoinformation technology.Results. The paper presents an architecture of distributed geoinformation technology focused on snow cover monitoring from measurements, data aggregation, and validation to their transfer to a centralized processing system. A prototype of portable user terminal modules for testing this technology is developed.Conclusions. The proposed architecture is capable of functioning in circumstances of limited telecommunication availability, while ensuring data integrity control and personalization of responsibility by introducing an electronic signature of each measurement session. This architecture can be expanded by developing and implementing modules for other types of measurements.

Background. Along with ammonites and septaries, concretions with fossils are increasingly being used as jewelry and ornamental materials in Russia. Such concretions are characterized by a wide range of sizes, as well as high decorative and technological properties, making them attractive materials for manufacturing diverse interior and jewelry products. The collection and processing of concretions with fossils was previously carried out in the Ulyanovsk region. In this paper, similar concretions found in the Republic of Kabardino-Balkaria are studied for the first time.Aim. Tо establish the stratigraphic position, mineral composition, and decorative and technological characteristics of concretions with fossils of jewelry and ornamental quality found in the Republic of Kabardino-Balkaria.Materials and methods. The collection sites of concretions with fossils and their stratigraphic position were studied. In total, 15 samples characterizing the main decorative and technological types were selected. Interior and jewelry items were manufactured from the concretions; typical samples were studied. A set of studies included the determination of luminescence (8 samples), microhardness (8 cycles), density (6 cycles), optical-petrographic analysis (3 sections), quantitative determination of mineral and chemical composition (2 samples), electron probe studies (2 samples).Results. Concretions with fossils of commercial quality are associated with lower Aptian deposits, representing marlstone with a large number of shells, mainly ammonites, and, to a lesser extent, bivalves. These comprise (wt %): calcite — 64.0, quartz — 18.7, microcline — 7.4, illite — 5.6, smectite — 2.7, kaolinite — 1.0, strontianite — 0.5, as well as traces of pyrite, apatite, albite, ilmenite, and goethite. Among the impurity elements, Sr in the amount of 0.0402 wt % is recorded.Conclusions. For the first time, the mineral and chemical (including micro-inclusions and impurity elements) composition of concretions with fossils of jewelry and ornamental quality are established. Factors determining their decorative and technological characteristics are identified. The possibility of using concretions with fossils for manufacturing a wide range of products, including jewelry, is shown. Concretions can be collected simultaneously with ammonites and septaries in river valleys without mining, thereby involving minimal costs and having no negative effect on the environment.
