Substantial thinking is traditional for a modern person, who is character­ized by a description of the world as a set of spatially localized objects-things-resources. The language of operational-technological control was developed on the basis of the tradition of A. V. Kolesnikova — V. F. Ponomarev's semiotic, multilingual representation of operational and technological control of a cer­tain class of complex systems, the basis of which is a verbal-sign, relational lan­guage for describing situations and the state of a controlled object. The lan­guage was specified using the conceptual theory of Z. D. Popova and I. A. Ster­nin, as well as the universal subject code of N. I. Zhinkin. The work desc­ribes the categorical core and subject-pictorial coding of the two-unit cat­ego­rical basis of the language of relations and connections of the object of op­erational and technological control, and also describes the conceptual scheme of the language and presents the results of the development of its mapping in­to the scheme "System of operational and technological control". The last has cognitive hybrid intelligent system as an actor.

The paper analyzes the problems associated with the provision of stable mobile radio communication in remote settlements located on the Baltic Sea coast. On the example of the urban - type settlement of Yantarny, the expedi­ency of implementing fifth-generation networks-5G-is justified. On the basis of accounting for the physical processes of radio wave propagation of the cor­responding frequency ranges, taking into account the density of buildings and terrain, calculations of the zones of confident radio reception in the study area were performed, the optimal location of cellular base stations was determined, and the choice of equipment was justified.

The generalized zeta-function is built by a dressing method based on the Darboux covariance of the heat equation and used to evaluate the correspond­ent functional integral in quasiclassical approximation. Quantum corrections to a kink-like solutions of Landau — Ginzburg model are calculated.

The problem of Boltzmann observers is discussed. It is shown that Page's proposed way of solving the problem includes this universe, which exists or­dered observers, exists for no more than a second, after which it is destroyed by a bubble of a new phase. The mass of the superheavy gravitino is estimated to be one more than Page's estimate.

The possibility of using adaptive control algorithms in wireless optical systems to improve their performance is considered. The use of feedback is proposed to create a dynamic system using the adjustment of the transmitted power level, changing the type of modulation and coding rate for atmospheric attenuation. Modeling and analysis of the system parameters at various dis­tances with a data transmission rate of 1 Gbit / s, taking into account the propagation of an optical signal in free space, have been carried out. The per­formance of the proposed wireless optical communication system with dynam­ic control is estimated at quality indicator BER no more than 10-8.

The paper presents the correction of a new technique for solving the prob­lem of sinusoidal waves on the surface of a homogeneous ideal fluid, associated with the refinement of the boundary conditions. The dispersion relation for long waves is found. The frequency value for sinusoidal waves in a stratified fluid is obtained.

The paper considers the features of the application of 5G technology in the electric power complex — in automated systems of distribution networks, relay protection and monitoring systems. Special attention is paid to the anal­ysis of the problems arising in this case in technical standards, network secu­rity is­sues, ensuring the necessary coverage areas. The prospects of integra­tion of 5G technology and power distribution networks are analyzed.
