This paper presents the methodology and outcomes of creating the Rail Vista dataset, designed for detecting defects on railway tracks using machine and deep learning techniques. The dataset comprises 200,000 high-resolution images categorized into 19 distinct classes covering various railway infrastructure defects. The data collection involved a meticulous process including ...

A simulation of the Stirling engine was carried out, where the temperature variability in the cooler and heater is taken into account, and the engine itself generates electric current. The study was carried out in the temperature range when the piston and displacer move synchronously. The possibility of increasing engine power by reducing hydraulic resistance in the regenerator ...

This study addresses the problem of selecting an equivalent material for soil testing using piles on a large-scale experimental setup. The approach involved conducting model tests in a metallic tank with specific dimensions, allowing for a 1:25 scale. Fine and medium-grained sand was used as the equivalent soil material. The main criterion for sand selection was its similarity ...

The article discusses the semantic aspects of Kazakh sign language and its characteristics. Semantics, a field within linguistics, focuses on examining the meanings conveyed by expressions and combinations of signs. The author delves into the inquiry of the degree of similarity between verbal and sign languages, highlighting their fundamental distinctions. The primary ...

In recent years, there has been increasing interest in the conversion of images into audio descriptions. This is a field that lies at the intersection of Computer Vision (CV) and Natural Language Processing (NLP), and it involves various tasks, including creating textual descriptions of images and converting them directly into auditory representations. Another aspect of this ...

In the work on the example of barium magnesium fluoride activated by tungsten system the existence of possibility of introduction of activators, modifiers into the formed ceramics are shown. Using unique properties of radiation synthesis of high synthesis rate is happened. The possibility of synthesis of magnesium fluoride activated by tungsten, barium fluoride activated ...

The relevance of this study stems from the desire to develop efficient and sustainable methods of energy extraction from low-temperature geothermal resources, which is of key importance in the context of finding alternative energy sources and reducing dependence on conventional, often nonrenewable sources. The purpose of this study was to analyze the organic Rankine cycle ...

We present a study of the Effective Field Theory (EFT) generalization of stochastic inflation in a modelindependent single-field framework and its impact on primordial black hole (PBH) formation. We show how the Langevin equations for the “soft” modes in quasi de Sitter background is described by the Infra-Red (IR) contributions of scalar perturbations, and the subsequent ...

The rapid development of digital technologies has transformed healthcare systems around the world, and telemedicine has become the primary solution to problems related to the availability and quality of medical care. This study examines the adoption of telemedicine in five Central Asian countries - Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, and Turkmenistan - by modeling ...

In this paper, we present new generalized wormhole (WH) solutions within the context of f (R) gravity. Specifically, we focus on f (R) gravitational theories formulated in the metric formalism, with our investigation centered on a power-law form represented by f (R) = Rχ . Here, is an arbitrary constant, and χ is a real number. Notably, this form possesses the advantageous ...
