The paper presents the use of corpus-based methods to investigate color terms in fiction. On the basis of Irving Stone’s biographical novel about the post-impressionist painter Vincent van Gogh, Lust for Life (1934), which established the genre of fictionalized biographies, a comprehensive analysis of color terms has been carried out, and a statistical profile of color terms has been developed.

This paper presents a novel method for parametric pressure-pulse generation in hydro-impulsive drives, replacing the traditional area-based parametric control with independent force-based control of two sealing elements. Unlike the classical approach proposed by Matveev, which is constrained by fixed geometric area ratios, our method uses individual springs and adjustment mechanisms to independently control the sealing elements.

The paper analyzes the method of identifying the maturity of concrete based on the results of measuring the temperature of concrete during its maturation using a temperature sensor built into the concrete. This method controls the maturity of concrete indirectly. The authors propose a method of controlling the maturity of concrete based on the results of direct measurement of its electrical parameters using a three-electrode capacitive sensor built into the concrete.

Gear transmissions of various sizes are used in various fields of mechanical engineering, automotive, marine, and aerospace industries according to the needs. This paper presents the modeling and analysis of the modal and harmonic characteristics of a planetary gear transmission for an elbow orthosis. Orthoses are used during the rehabilitation of patients in the postoperative period or during the restoration of lost limb functions. When modeling the planetary gear, the connection elements are made of 45 steel and PLA polylactide.

Shafts of various sizes are used in various fields of mechanical engineering, automotive, marine and aerospace industries to transmit torque according to requirements. In this paper, we simulate and analyse the modal and harmonic response of a shaft on which a satellite of a planetary gearbox for an elbow orthosis is mounted. The orthoses are used during the rehabilitation of patients in the postoperative period or during the regeneration of lost limb functions. Steel 45 and PLA polylactide were used in the shaft modelling.

The rotor is a key element of high-speed mechanisms that are widely used in various industries, such as laboratory centrifuges used to separate mixtures of different fractions, gas turbines, industrial compressors, engines, and others. The main requirement for such mechanisms is reliability and safety during operation. To ensure the above requirements, it is necessary to determine the stress-strain state of the most loaded structural elements of the system and the dynamic characteristics.

The role of the media is determined by the irsocial purpose, which is primarily to inform and shape public opinion. The division of the pressa ccording to the nature of its audienceis one of the main criteria for classifying the media, where along with specialized publications for specialists in a particular field the reare newspaper sand magazines for non-specialists.

Aim. The aim is to construct the mathematical model of the movement of loose material in a vibrating separator. Method. The calculation scheme of the vibration separator with two eccentric vibrators with an independent drive was built. Based on the scheme, it is assumed that the vibration separator performs only vertical oscillations in the plane of rotation of the eccentric vibrators.
