This paper presents, for the first time, an integrated method for flight planning of stratospheric gliders operating within swarm-based multilevel systems, which combines frequency analysis of time series of key flight performance indicators with an adapted Irwin criterion for filtering ano...

The article deals with the actual problem of ensuring the vibrational reliability of aircraft engine blisks by conducting modal analysis, which makes it possible to determine natural vibration frequencies and modes. The localization of vibrations, increased resonance stresses and threat of&...

The article considers the application of a platinum resistance thermometer Pt1000 for accurate measurement of water temperature in an automated terrarium. A mathematical model of the resistance-temperature dependence R(T) based on the Callendar–Van Dusen equations is presented. The static ...

The paper deals with the use of vibration technology, which is an effective means of reducing residual stresses in castings. Vibration can be used to achieve a stress relief sufficient to prevent further warping of castings due to the redistribution of residual stresses. In&#...

Concrete floor pavements in agro-industrial facilities operate under combined abrasion, impact, moisture and organic environmental exposure, which accelerates degradation of the surface layer and increases dust formation. The study evaluates the use of polystyrene waste dissolved in toluene as a...

The study addresses the urgent problem of rapid structural integrity assessment for VVER-1000 reactor pressure vessels (RPVs) under pressurized thermal shock (PTS) conditions during lifetime extension. Given the high computational complexity of three-dimensional finite element modeling, the authors p...

Titanium alloys offer advantages over steel due to their low specific density and high specific strength. This makes them indispensable in products for the aerospace, marine, and damping industries, among others. However, their poor frictional properties significantly limit their applications.&#...

This paper investigates the adaptation of the direct boundary element method (BEM) for analyzing stationary vibrations in load-bearing structural components, specifically beams and plates, under intense dynamic loads. The study addresses the challenge of designing high-efficiency mitigation systems&...

The paper investigates the efficiency of the cavitation method for impregnating textile materials and compares it with the conventional immersion method. The relevance of the study is determined by the need to improve the efficiency of textile impregnation processes using special subst...

The paper considers approaches to mathematical modeling of the gas consumption process based on three models: a model based on a cyclic random process and the classical ARIMA and SARIMA models. The gas consumption process is characterized by the presence of a trend, seasonali...

Large language models (LLM) provide opportunities to generate user interfaces directly from natural- language intent, but the emerging generative-UI literature remains focused primarily on web and chat contexts rather than smart systems. Smart-system interfaces are characterized by stricter demands,&...

A three-dimensional numerical model of a cast-in-situ raft foundation interacting with elastic subsoil was developed using the Finite Element Method (FEM) in the LIRA-FEM software environment, incorporating the GRUNT module for subsoil modelling. The analysis considered both isolated and two-row...

This article presents a modular, object-oriented architecture for the PBM (Porous Media Modeling) library, a Java-based system designed to model consolidation filtering kinetics in hierarchical porous media with two- and three-level porosity structures. Developing extensible software architectures f...

The article analyzes approaches to creating digital information guides to support the activities of small museums of local importance. Recommendations have been developed for the implementation of a digital application based on industry standards in working with exhibits, an intuitive metho...

This study deals with the application of modern Artificial Intelligence technologies, mainly deep learning methods based on recurrent neural networks of the Long Short-Term Memory (LSTM) type, for the construction and analysis of Ukrainian-language corpora. The research attention is directed...

The aim of this work is to investigate the influence of complex contact interaction conditions on the stress-strain state of an elastic bilayer body of finite dimensions. The case of loading the body with a perfectly rigid, smooth, flat indenter is considered. The following&#...

This article presents the results of a numerical study on the influence of representative volume size and the concentration of initial nucleation centers on the elastic properties of polycrystalline copper, taking into account the anisotropy of its microstructure. The modeling was carr...

In the process of creating various equipment, machines, mechanisms, devices and other constructions, the technological process of thermal shrink fit is often used. It is reasonable to heat ring discs for fitting them on round axes or in cylindrical holes in order to achieve&#...

The article presents an approach in the creation of an intellectualized dialogue system for automation of communication with university applicants during admission campaigns. Retrieval-Augmented Generation (RAG) architecture, which combines search of relevant information with generation of a response ...
