In asymptotic calculations, the equilibrium form of a charged drop is found in a non-uniform electrostatic field created by an extended spheroid modeling a rod supported at a constant electric potential. It was found that the size of a small axis of a spheroid (rod thickness) creating a field considerably affects an equilibrium form of the charged drop. It is possible to describe the distortion of a spherical form of the surface of the charged conducting drop of ideal incompressible liquid in a non-uniform electrostatic field of a rod (with an accuracy bigger one percent of size) by the superp

One of the important directions in the field of creating new structural and functional materials is the study of materials with a complex structure and unique strength or temperature properties. Due to the heterogeneity of their structure, such materials are called “structurally sensitive”. The heterogeneity of the structure of such materials is justified by the technological features of their creation. Structurally sensitive materials can be obtained by compacting nanopowders, deposition on a substrate, etc. The paper considers a mathematical model of heat propagation in a composite rod. At o

Abstract We consider an active nematic phase and use hydrodynamical equations of it to model the activity as an internal field. The interaction of this field with the nematic director in a confined geometry is included in the Hamiltonian of the system. Based on this model Hamiltonian and the standard field theoretical approach, the Casimir-like force induced between the boundaries of such a confined film is discussed. The force depends on the geometrical shape and the dynamical character of the constituents of our active phase, as well as the anchoring conditions. For homeotropically aligned r

The development of fields that are at a late or final stage of operation is carried out mainly with the use of downhole sucker rod pumps. The most characteristic failures for these installations are rods parting-twist off and malfunctions of pump valves. The methods of eliminating these accidents vary significantly the parting or twist off of the rods involves lifting of the downhole equipment, and the "sticking" of the shut-off valve assembly of the pump is eliminated by "resuscitation" of the downhole equipment (flushing with water, hot oil or solvent).

The creation of technology for the analysis of wattmeter charts to control the main equipment of oil fields has always been of both theoretical and great practical interest. Numerous experiments have shown that the wattmeter chart of their electric motor is a highly noisy signal, and a significant part of the diagnostic information is contained in the estimates of the noise variance and the cross-correlation function between the noise and the useful signal. The lack of technologies for their analysis made it difficult and still makes it difficult to use the wattmeter chart to control the indic

When developing technological systems, it becomes necessary to transmit information over significant distances without the use of traditional means of communication, because they can not be used, for example, in the field of geonavigation when drilling inclined / horizontal wells. One of the possible channels for transmitting information in this area is the hydraulic communication channel (HCC). Therefore, at present, the task of developing an effective method and approach for transmitting information on the HCC becomes urgent. The purpose of this work was to create a mathematical model of the

Many new developments in the field of creating promising building materials relate to polymer fiber composites for reinforcing concrete constructions. The most effective use of such composites is provided by carbon fiber reinforcement. To date, the issues related to design, calculation and use of concrete constructions with carbon composite reinforcement under dynamic compressive loading have not been well studied.

The paper investigates the concept of the “zvukoobraz” (sound-image) in literary-philosophical articles and lectures on poetics by Vyacheslav Ivanov, specifically its origins, meaning, and context. This term is closely connected with the “Lautbild” of Wilhelm Wundt, translated in Russian as “zvukovoi obraz” by Tadeusz Zieliński in his widely known article about the German philosopher (1901). Viktor Shklovsky, one of the leading theorists of Russian Formalism, also wrote about “zvukovye obrazy” in his paper “About Poetry and Zaum Language” (1916).

Purpose: Nowadays, in the millimeter frequency range, the dielectric waveguides of various modifications have certain advantages over the standard metal waveguides, primarily due to the possibility of creating functional units based on them. This is due to the relative simplicity and low cost of manufacturing the dielectric waveguides and functional units using them, the high degree of their integration with active elements, the use in their manufacture of different dielectrics and polymers with a wide range of material constants and a variety of mechanical properties (in particular, some mate
