MATHEMATICAL MODELING OF THE DRIVE
OF A HYDRODYNAMIC STEAM GENERATOR BASED
ON A SEGNER WHEEL IN ORDER TO JUSTIFY
THE CONDITIONS FOR MINIMIZING ITS ENERGY
CONSUMPTION.
UDC 621.31
DOI 10.24412/2413-7383-2024-1-4-21
Language: Russian
Annotation:This study confirms the expected effectiveness of using the additive effect of technologies to minimize
external energy consumption by a hydrodynamic steam generator built on a Segner wheel. Thanks to
this combination of technologies, a steam generation regime has been achieved when its output
product, water vapor, is at the same time a source of reactive force that rotates the wheel, and therefore
compensates for the energy consumption for its production during desalination of water by distillation.
Keywords: steam generation, Segner wheel, centrifugal force, cavitation, Laval nozzle,
mathematical model, energy balance, parametric optimization.

THE APPLICATION OF TWO-DIMENSIONAL FREQUENCY
ANALYSIS IN THE SOME LEADING INDICATORS
EVALUATION IN CONSTRUCTION.
UDC 519.234, 519.711
Language: Russian
Annotation:Two-dimensional frequency analysis examines the seasonal dependence of some leading indicators in
the construction. The purpose of the research is to compare the impact of seasonality on the factors, that
hinder the operations of construction companies by using methods of multivariate analysis.
Keywords: management in construction, leading indicators, seasonality, two-dimensional
analysis, contingency tables.

“CIVILIZATION-LICHEN” AND “CIVILIZATION-MAGNET”:
MODELING SYMBIOSIS OF HUMANITY AND ARTIFICIAL
INTELLIGENCE, WITHIN THE MIND-MATTER THEORY.
UDC 004.8; 004.94; 001
Language: English
Annotation:The types of future coexistence between human society and future general AI depend both on the
types of AI being developed today and types of existing societies. The range of possible
partnerships, suggested by science fiction, range from elimination of humans to happiest life under
the care of AI. This paper considers evolution of two types of AI (open- and closed-access,
controlled by society and authorities, correspondingly), as well as corresponding societies.
Keywords: artificial intelligence, modeling, mind-matter theory, sociology, evolution,
civilization, human-AI interaction, open-source.

ANALYZING THE EFFECTIVENESS OF DEEP LANGUAGE
MODELS FOR THE TASK OF TONE DETECTION
IN RUSSIAN-LANGUAGE TEXTS.
UDC 004.912
Language: Russian
Annotation:The article decribes the process of solving the task of sentiment analysis across texts of varying
lengths, such as customer reviews and news articles. A methodology involving fine-tuning machine
learning models based on RuGPT-3 and RuBERT is proposed, achieved through the substitution of
the last linear layer with a classification layer having outputs corresponding to the number of
classes (neutral, positive, negative). Research indicates the advantages of utilizing RuGPT-3-
based models, revealing a notable increase in predictive quality despite their lower operational
speed. Additionally, a comparison of models trained on one text type to predict sentiments in
another was conducted. The results show that models trained on news articles exhibit slightly
superior classification of reviews. However, the resulting accuracy falls short for the multimodal
application of trained models.
Keywords: language model, natural language processing, sentiment analysis, finetuning, GPT, BERT.

INVESTIGATION OF THE MECHANISM OF ADAPTATION
OF AN IN-TUBE ROBOT TO THE DIAMETER OF THE PIPE
AND ADJUSTMENT OF TRACTION FORCE WHEN USING
OMNIDIRECTIONAL WHEELS.
UDC 538.3
DOI 10.24412/2413-7383-2024-1-63-74
Language: Russian
Annotation:In this article, the parameters of the operation of the mechanism of adaptation to the pipe diameter of
an in-tube wheeled robot operating on the principle of "spacer" are investigated. When applying this
technique, the force and torque on the running screw of the mechanism necessary for the wheels to
contact the inner surface of the pipe and subsequent adjustment of the traction force of a wheeled
robot with a parallel mechanism are determined. This is achieved using a pressure sensor.
Keywords: adaptation mechanism, wheeled robot, omnidirectional wheel, pipe, force,
torque, traction force, pressure sensor.

EXPANSION OF IMPLEMENTATION OF DIGITALIZATION
AND ARTIFICIAL INTELLIGENCE INTO THE RUSSIAN
ECONOMY.
UDC 004.8
Language: Russian
Annotation:The article examines the processes of development of digitalization in the Russian economy.
Methods and models for digitalization of economic relations of the state are proposed. It has been
revealed that digitalization is implemented through gradual transformations in the economy,
affecting the basic socio-economic and management structures of the state. Promising artificial
intelligence technologies and the risks of their implementation are considered. A review of the
relationship between correlation analysis and digitalization in the study of economic processes is
carried out.
Keywords: digitalization, economics, technology, methods, models, artificial intelligence,
cycle, calculations, forecast.

ANALYSIS OF THE POSSIBILITIES
OF USING AIRCRAFT IN CONTROL
OF TERRAIN CONDITION.
UDC 528.013
DOI 10.24412/2413-7383-2024-1-94-102
Language: Russian
Annotation:The article analyzes the main characteristics of domestic and foreign unmanned aerial vehicles in
order to make the optimal choice for further monitoring of the terrain. After analyzing the
advantages of each of the aircraft, the best option is an unmanned aerial vehicle with lidar installed
as a photo-fixing element.
Keywords: terrain, glider, condition, laser, LIDAR.
