Objectives Firefighting is one of the tasks that is physically difficult to perform and carries a high risk of injury and death. A better understanding of the underlying factors that influence the causes of fire scene injuries can improve firefighters’ safety. For this reason, the study aimed to determine the importance of Smart Personal Protective Equipment and wearable technology in protecting the health and safety of firefighters by using them instead of traditional equipment and systems. According to expert opinions and literature reviews, the dangers faced by firefighters have been determined to be thermal, physical, biological, environmental, and chemical. Methods Analytical Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) methods were used in the study. The AHP method was preferred because it is a systematic decision-making method that includes both ranking and comparison techniques. The PROMETHEE method was preferred because it provides the opportunity to make effective decisions in a very short time by basing the decision-making process on a scientific basis. In addition to the graphical representation of the ranking of alternatives, it offers decision-makers the opportunity to make various statistical analyses. Results The weights of the hazards were calculated using the AHP method. Physical hazards accounted for the highest weight. PROMETHEE was used in the ranking of wearable smart technological products to protect the health and safety of firefighters. Conclusions Products are listed as Personal Protection System, PROeTEX PPE, Wearable IoT Device, Flame Resistant Shirt, Fall Detection Systems, Smart Wearable Underwear, and WASP. With the study, it was concluded that the risk of firefighters being trapped would play an essential role in the prevention of death and injury. Improvements in wearable technological products used in the fire department will yield better results and increase safety.

DEVELOPMENT OF AUTOMATED CONTROL SYSTEM AND REGISTRATION OF METAL IN CONTINUOUS CASTING

Context. Modern industrial enterprises face challenges that require introduction of latest technologies to improve efficiency and competitiveness. In metallurgy, one of key stages is continuous casting, where quality of products and economic performance of enterprise depend on accuracy and efficiency of process control. Products made using continuous casting technology are widely used in various industries due to their high mechanical properties, structural uniformity and cost-effectiveness. The development of automated metal management and registration system is becoming not only relevant, but also necessary to ensure stable and efficient production. The problem of improving quality of metal products has always been one of most important tasks in steel industry. Imperfect technological processes, human error and equipment malfunctions can lead to defects in finished metal products. This, in turn, affects final characteristics of products, their durability and reliability. To date, available sources have not yet found complete solution to this problem. Therefore, it is necessary to formulate problem and develop algorithm for operation of automated system for controlling and registering metal in continuous casting. Objective. The goal of work is to develop automated metal management and registration system to improve quality of metal products. Method. To achieve this goal, parametric model was proposed, which is formalized on basis of set theory. The model takes into account key parameters of continuous casting process: material characteristics, structural features of crystallizer, casting modes, metal level in crystallizer, and position of shot stopper. Results. The problem was formulated and key parameters were determined, which are taken into account in system’s algorithm, which made it possible to develop system for controlling parameters of continuous casting to solve problem of improving quality of metal products. Conclusions. To improve quality of metal products and stability of casting process, parametric model was created that is comprehensive, allows optimization of key parameters and ensures accuracy of process control by integrating not only modes of product formation, but also takes into account specific properties of source material (chemical composition of material grade, etc.) and design features of casting plant. Algorithm for automated control system has been developed that takes into account relationships between certain key parameters and ensures optimal control of casting process. Based on proposed complex parametric model and algorithm, automated control and metal registration system was created. The focus of work is on quality and efficiency of metal management and registration in continuous casting, based on modern methods of computer science and engineering. A comprehensive experimental comparison of developed system with commercial analogs in real production conditions was carried out, which allowed us to objectively assess its efficiency and reliability.

Study on Cavitation Erosion Mechanism of Ultra-High Molecular Weight Polyethylene (UHMWPE) and Polytetrafluoroethylene (PTFE)

Polymer materials possess low density, high strength, corrosion resistance, and excellent cavitation erosion resistance. As a result, they are widely used in marine, water conservancy, and other engineering equipment as replacements for metal materials. However, polymer friction pairs working in a water environment for an extended period are easily damaged by cavitation erosion. In this work, the cavitation behavior of polytetrafluoroethylene (PTFE) and ultra-high molecular weight polyethylene (UHMWPE) in deionized water and seawater is investigated through experiments and computational fluid dynamics (CFD) simulations. The results indicate that the cavitation erosion resistance of UHMWPE is significantly better than that of PTFE, and the UHMWPE has four cavitation process stages, while the PTFE has only three cavitation stages. 316 L counterparts in the seawater corrosion and cavitation coupling effect of a large number of metal particles off and wash polymer material surface, so that the cavitation erosion of PTFE and UHMWPE is more serious in seawater environment. CFD simulation demonstrates that the cavitation erosion zone under the radiator shows a semicircular distribution. Meanwhile, the formation of ring-shaped cavitation pit is related to the distribution of bubbles on the surface of the radiator. The cavitation rate of PTFE and UHMWPE is slowed down by the “water cushion effect.”

Real-time monitoring of aero-engine vibration signals by wireless communication technology

Abstract The conventional way to monitor the vibration signals of aircraft engines is to use wired communication sensors to transmit and collect the signals on a fixed platform on the ground. The signal acquisition equipment of wired communication technology has various drawbacks, resulting in the inability to collect vibration signals when the object under test is in real operating conditions. Based on previous studies, this research team uses a 2.4G wireless transmission scheme to realize short-distance wireless transmission of aero-engine vibration signals, and a 4G cellular communication scheme to realize long-distance wireless transmission of aero-engine vibration signals. The acquired signals are displayed and monitored using the tool developed in LabVIEW2022. The designed tool is successfully applied in the engineering practice of engine maintenance, realizing the remote real-time monitoring of the engine operation status, shortening the monitoring cycle of the equipment from hourly to real-time level, and greatly facilitating the technical support work of engineers and technicians.

Wireless Alerts and Data Monitoring from BNNO-MWCNTs/PDMS Composite Film-Based TENG Integrated Inhaler for Smart Healthcare Application.

In recent years, the implementation of energy-harvesting technology in medical equipment has attracted significant interest owing to its potential for self-powered and smart healthcare systems. Herein, the integration of a triboelectric nanogenerator (TENG) is proposed into an inhaler for energy-harvesting and smart inhalation monitoring. For this initially, barium sodium niobium oxide (Ba2NaNb5O15) microparticles (BNNO MPs) are synthesized via a facile solid-state synthesis process. The BNNO MPs with ferroelectricity and high dielectric constant are incorporated into polydimethylsiloxane (PDMS) polymer to make BNNO/PDMS composite films (CFs) for TENG fabrication. The fabricated TENG is operated in a contact-separation mode, and its electrical output performance is compared to establish the optimal BNNO MPs concentration. Furthermore, multi-wall carbon nanotubes (MWCNTs), a conductive filler material, are used to enhance the electrical conductivity of the CFs, thereby improving the electrical output performance of the TENG. The robustness/durability of the proposed BNNO-MWCNTs/PDMS CF-based TENG are investigated. The proposed TENG device is demonstrated to harvest electrical energy from mechanical motions via regular human activities and power portable electronics. The TENG is integrated into the inhaler casing to count the number of sprays remaining in the canister, send the notification to a smartphone via Bluetooth, and harvest energy.

Preliminary results of the deployment of the Smart Readiness Indicator in Italy

Abstract The Smart Readiness Indicator (SRI) was firstly introduced by the 3rd Energy Performance of Buildings Directive as an optional certification scheme to rate the smart readiness of buildings and promote building smartness throughout Europe. According to the 4th EPBD recast the Commission shall, by June 2027, adopt a delegated and an implementing act by requiring the application of a common scheme for rating the smart readiness of buildings to highly energy intensive non-residential buildings. Although the SRI legal framework is now well defined, on the technical hand, national authorities must provide details of the SRI calculation for their own building stocks. Nowadays, only a generic technical framework designed after extensive European stakeholder consultations is available, allowing the SRI currently being officially tested in 13 EU countries. The aim of this paper is to provide an overview of the research activities currently ongoing at a national level on SRI to define a methodological approach for SRI calculation tailored for the national context. The standard and tailored methodologies were then compared using two representative case studies in the tertiary sector of the Italian building stock. Despite the high level of technological equipment, the results showed that the SRI indicator obtainable with the standard methodology was low. This suggests that an adaptation of the catalogue of smart-ready services will be required to make it more responsive to the characteristics of existing buildings and to the devices currently available on the market.

Time-dependent corrosion behavior of EH36 steel caused by Pseudomonas aeruginosa based on big data monitoring technology

Marine microbial corrosion poses a significant threat to the safe service of marine engineering equipment. Previous studies have often failed to thoroughly analyze the continuous and prolonged microbial corrosion process, resulting in an incomplete understanding of microbial corrosion mechanisms involved at various stages and the development of ineffective control strategies. This study employed a corrosion big data online real-time monitoring technique to investigate the time-dependent corrosion behavior of EH36 steel caused by Pseudomonas aeruginosa in aerobic environments over a 30-d incubation period. It was found that P. aeruginosa accelerated the corrosion of EH36 steel in the early stages by enhancing the cathodic oxygen reduction process. As oxygen levels declined, P. aeruginosa transitioned from aerobic to anaerobic respiration, promoting corrosion through biocatalytic nitrate reduction. In the later stages, the reduction in sessile cell counts, extreme low oxygen concentration, and dense surface film increased the charge transfer and film resistances, ultimately leading to corrosion inhibition. The weight loss and electrochemical data confirmed the effectiveness of the big data monitoring technique in investigating microbial corrosion, which provides new approaches for diagnosing and preventing microbial corrosion.

High temperature resistant thin film thermocouple prepared based on inkjet printing

Thin film thermocouples (TFTCs) are known for their wide temperature measurement range and high precision, showing significant potential in aerospace and steel metallurgy applications. The lack of effective manufacturing techniques has been a major barrier to their mass production. Inkjet printing, a high-quality thin film additive manufacturing process operating outside vacuum environments, offers a viable solution for large-scale practical applications of TFTCs. We successfully fabricated ITO/In2O3 high-temperature thin film thermocouples on ceramic substrates using inkjet printing technology. We developed a printable ink with excellent fluid characteristics, suitable for constructing the sensitive layer of the thermocouples. The fabricated sensors exhibited outstanding high-temperature stability and reliability, with a maximum measurement temperature exceeding 800 °C, surpassing the upper limits reported in other inkjet-printed temperature sensors. Continuous operation at 800 °C for 8 hours resulted in a low drift rate of 1.53 °C/h. The sensors demonstrated 98.55% high repeatability and 98.7%FS high accuracy across a wide temperature range, with a maximum Seebeck coefficient reaching 111 μV/°C, superior to most other high-temperature thin film sensors reported in literature. These findings show great potential in enhancing the safety of aerospace engineering equipment and ensuring the quality of products in the steel metallurgy industry.

КОМП'ЮТЕРНИЙ МОДУЛЬ ДЛЯ АНІМАЦІЇ РУХУ ШАТУННО-ПОВЗУНКОВОЇ ГРУПИ ПРОГРАМИ KDAM ПРИ ВИЗНАЧЕННЯ КІНЕМАТИЧНИХ ТА ДИНАМІЧНИХ ПАРАМЕТРІВ

The development of new schemes of the thread feeding system requires an operational assessment of the value of the tension in front of the working zone. The objective function in the tasks of optimizing technological processes is the minimum necessary tension. The development of special computer programs for determining the tension in the working area makes it possible to determine the necessary technological parameters. The variable parameter in the objective function is the sum of the angles of coverage of the working bodies by the thread. The use of a computer program allows you to determine the tension and change in relative tension in the filling zones of technological machines, which allows you to optimize the shape of the thread supply line even at the stage of designing the technological process. A computer module was developed for the animation of the movement of the connecting rod-slider group, which is a component of the KDAM program for determining the kinematic and dynamic parameters of the connecting rod-slider group of the mechanisms of textile and light industry machines, which allows at the preliminary design stage to visually evaluate the behavior of individual links of the connecting rod mechanism of the slider group and determine the coordinates, projections of velocities and accelerations of the center of mass of the connecting rod, the slider and the points of attachment of the links of the Asura groups on the connecting rod. The KDAM program is a structural element of a computer software complex for assessing the intensity of technological processes in the light and textile industry when determining the change in the relative tension of the thread in the filling zones on the technological equipment. Kinematic and dynamic analysis of flat mechanisms plays a significant role in the design of new mechanisms and modernization of existing ones. The results obtained during these studies can be used to calculate the strength of individual links, their inertial characteristics, optimization of structural parameters of mechanisms, and minimization of consumed energy. The computer module of the KDAM program for determining the kinematic and dynamic parameters of the connecting rod-slider group of mechanisms of light industry machines allows you to determine the coordinates, projections of velocities and accelerations of the center of mass of the connecting rod, slider and the point of attachment of the links of the Asura groups on the connecting rod. During the dynamic analysis of the operation of the connecting rod-slider group, the projections of the full reaction in the joints between the crank and the connecting rod, between the connecting rod and the slider, and between the slider and the fixed guide are determined.

Purpose. To carry out a kinematic analysis of a flat twelve-link hinged mechanism with three leading links, the basis of which is a structural group of links of the third class of the fourth order with rotational kinematic pairs, which is used in technological equipment. Methodology. The kinematic study of a flat complex mechanism of the third class with three leading links was performed using the mathematical modeling method in the Mathcad software environment. Findings. Using the method of mathematical modeling, the mechanism was presented in the form of free vectors built on its links, for which, taking into account the presence of three leading links, three vector contours were selected, which made it possible to draw up a system of vector equations of their closedness with further solving by a numerical method in the Mathcad software environment.

Schematic modeling of the mechanism with three leading links was performed, a visualization schedule of its kinematic scheme was built, and a valid version of its assembly was obtained from many possible ones, for which the values of kinematic parameters of all its links were determined. Practical value. An analysis of the effect of the kinematic parameters of the three leading links of the third-class mechanism on the movement of the working body of the technological equipment was carried out. From the analysis of the obtained research results for the cycle of the mechanism the reason was found for the incomplete technological stoppage of the link, which should provide the working body of the machine for the required period of time. Recommendations of the elimination were made to identify the deficiency and proposals for the need to improve the drive of this equipment.

THE EVOLUTION OF COMMUNICATION AND INFORMATION TECHNOLOGIES IN EDUCATION

This paper aims to describe, based on an analysis of what is contained in the literature, the introduction and evolution of information and communication technologies (ICT) in education, thus constructing a historical record of these technologies. The project is justified by the relevance of the topic and the importance that ICT represented during the pandemic period, practically saving education from two years of social isolation, leaving millions of students out of school, enabling, even with some difficulties encountered by teachers and students, the continuity of pedagogical activities, minimizing the educational losses of a period never seen before in the history of education. It is clear that these ICT should be incorporated into the pedagogical projects of the courses, since Ifes has an academic environment Moodle (Modular Dynamic Object-Oriented Learning Environment) available that enables pedagogical activities for teachers and students. Given the many new digital technologies that have emerged in recent times, it is possible to see that digital communication and information technologies have become a fertile field for technology companies, developers, and researchers in the area of ​​technology and education, since they have seen technologies as a tool capable of providing a transformation of teaching-learning methods and practices that are important for achieving pedagogical objectives, thus not diminishing the role of educators, nor even replacing them, but allowing some tasks and functions to be expanded and diversified. It is also worth noting that TDCI encompasses other sectors, becoming multidimensional with roots spread throughout society. The legislation that governs the introduction and use of technological equipment in the classroom has advanced and encouraged its use in everyday school activities.

Broadening the definition of healthcare products in global trade: Insights from a new classification

International trade in healthcare products took off during the 2000s, paralleling the peak of hyper-globalisation. Two decades later, the Covid-19 pandemic highlighted the importance of health security for governments. This crisis brought issues of industrial sovereignty to the forefront and exposed vulnerabilities within global production networks. However, the intricate web of global value chains has compromised the traceability of these essential goods. Additionally, the classification of healthcare products across multiple industries in standard trade and production nomenclatures complicates their identification and further obscures the analysis. In this paper, we systematically identify products that address the needs of national health systems and gather them into a single industry grouping to evaluate the scale and trends in trade. This healthcare industry grouping, encompassing a broad array of products—medicinal products and their compounds, medical technology equipment, and small medical materials— has demonstrated the highest relative growth among all industry groupings since 2000. Our study provides a detailed examination of the nature of global trade in the healthcare industry grouping and its five branches, categorized by production stage (intermediate and final) and quality/price range. We analyze the positioning of advanced economies in comparison to the rest of the world and offer insights into the geographical and geopolitical breakdowns of healthcare industry trade, both within and between country blocs.

DESIGN OF TECHNICAL SYSTEMS USING SIMULATION-HARDWARE MODELING COMPLEXES

Context. Radar means of space control are large science-intensive technical systems. The development of the new generation of radar stations is a complex process related not only to the search for new technical solutions and technologies but also to the assessment of their effectiveness in terms of parameters and cost. The domestic school of designing and creating space control systems has great scientific and technical potential, which allows the developmentof promising radars. However, the development of such systems is carried out with the exception of several stag- es, which are established according to the regulatory procedure, since the creation of functionally finished systems and the sys- tem as a whole is possible only at the exploitation place, therefore the manufacturing process is startedimmediately. The bench equipment used for product testing due to its monofunctionality cannot provide the verificationof functionally finished systems. Ensuring the effective implementation of the objective functions requires a long and expensive process of finding new circuit solutions using the developed equipment as a test bench, which consumes its resources. Solving the problem is possible only by creating a tool that would allow the developer to conduct the entire list of tests of the entire system hierarchy directly during the development process. Such a tool can be created using simulation-hardware modeling complexes. Objective. The goal of the work is to study the possibility of developing simulation-hardware modeling complexes for testing prospective science-intensive complex technical systems. Method. The method of imitation and semi-natural modeling is used. Results. The main methods of building a simulation-hardware complex have been developed and the possibility of using simulation tools, models, and standard technological radar equipment to form its architecture has been substantiated. It is shown that the creation of new complexes can be based both on the use of already existing systems in the operational radar and on the development of new elements. Conclusions. The presence of scientific and technical development and practical experience of the domestic developer of the space control radar makes the implementation of the new complex quite realistic, and the implementation of the test technology and practice using the simulation hardware complex will allow to reduce the total development costs.

Prevalence of Keratoconus and Keratoconus Suspect among a sample of Iraqi Children with Refractive Errors: A Cross-Sectional Study

Background: Keratoconus (KC) is a chronic, bilateral, non-inflammatory degenerative condition with severe consequences. Objective: To assess the prevalence of KC and Keratoconus Suspect (KCS) in a pediatric population with astigmatic error ≥1 diopter (D) and non-axial myopia. Methods: Between March and October 2022, a cross-sectional study was done with a group of 6–18-year-old kids with an astigmatic error of ≥1 D or non-axial myopia who went to the pediatric ophthalmology clinic at Ibn Al-Haitham Teaching Eye Hospital in Baghdad, Iraq, for regular checkups. All patients got a thorough eye examination and corneal imaging using the Corneal Tomography System (CSO) Sirius equipment and Scheimpflug technology. Results: The majority of patients were females aged 110–14 years (55%). The frequencies of KC and SKC were 13.5 and 119.6%, respectively. The proportion of KC was substantially higher for those above the age of 14. Patients with KC exhibited considerably larger cylinder and axis measurements. Participants with inferior cones and an asymmetric Bow Tie exhibited greater rates of KC (51.2% and 29.4%, respectively). Except for Pachy-Thin and corneal volume mean values, all other metrics were considerably greater in KC and KCS patients than in control patients. Conclusions: The high prevalence of KC and KCS emphasizes the importance of this issue and the necessity for a systematic strategy for screening in pediatric age groups with refractive error.

Determining the force parameters of the working process to clean the udder nipples of cows

The object of this study is the force parameters of the working process when cleaning the udder nipples of cows from contamination. Failure to provide adequate care for a cow, especially concerning its udder, could lead to significant health and productivity problems. On the other hand, utilizing modern tools, devices, and materials could improve the sanitary and hygienic conditions for milking cows and udder care, thus leading to better overall outcomes. As part of the research, mathematical expressions were derived theoretically, allowing the determination of the force parameters of the working process for cleaning cows’ udders from contamination by expanding the range of the device’s functional characteristics. Distinctive features of the results regarding the solution to this problem is evaluation of the elasticity force exerted by the lint bundles on the nipple during the rotation of the brush device’s drum and the circular force generated by the brush lint. The developed algorithm of the work process aimed at cleaning the nipples and udders of cows made it possible to combine a set of clearly defined and sequentially performed operations into a single whole. It has been demonstrated that the efforts required to retain different types of contamination on the skin vary significantly. To objectively determine it, a new device has been designed. Its distinctive features are the precision of measurement and simplicity of operation. Following laboratory testing, it was established that the highest contaminant retention forces were exhibited by solid manure (Fret=40±3.21 N), while the lowest values were observed for sawdust (Fret=19±2.17 N) (p ≤ 0.001). The developments are relevant and could be used at cattle breeding farms of various forms of ownership, the scientific community, and at industrial enterprises manufacturing technological equipment.
