When creating and manufacturing traditional and new composite materials, for example, by additive manufacturing, and when creating structures and structures in engineering calculations, new techniques, finite element computational software systems, and neural network technologies are used, which are used in the creation of modern metal and composite materials, analysis of mechanical characteristics of materials, forecasting loads on the structure, optimization of structures and calculation of their construction characteristics. The distinctive features of modern composite materials are shown. The main types of composite materials are considered: talc, diatomite, calcium carbonate, gibbsite, barium sulfate, feldspar, nepheline, aragonite, calcium carbonate, wool, silk, cotton, linen, jute, wood pulp, asbestos, fiberglass, metal fibers, quartz fibers, basalt fibers, polyamide fibers, polyester fibers, polyvinyl alcohol fibers, carbon fibers, viscose fibers. The physical and mechanical characteristics of composite materials (based on epoxy, aluminum, carbon, magnesium, and nickel matrices) and traditional (steel, aluminum, brick, concrete) building materials are presented. The disadvantages of such composite materials as carbon fiber, fiberglass, organoplastics, textolite, carbon concrete, and polystyrene concrete are presented. Deformation diagrams of some types of fibers for composite materials are considered: high-modulus carbon fibers, high-strength carbon fibers, aramid fibers, glass fibers, and basalt fibers. The advantages of the system of external reinforcement of building structures with composite materials are described. Examples of reinforcement of building structures are considered: reinforced concrete reinforcement; reinforcement of floor slabs; reinforcement of columns; and reinforcement of brick walls.","PeriodicalId":515824,"journal":{"name":"The American Journal of Engineering and Technology","volume":"41 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Model-View-Intent (MVI) architectural pattern has proven to be an effective approach to achieve these goals due to the strict separation of responsibilities between components, unidirectional data flow and an emphasis on immutability. This article discusses the basic principles of the MVI architecture, its advantages and disadvantages, as well as its impact on the testability and maintainability of applications. Using MVI allows you to improve the predictability of application behavior, simplify debugging and state management, and also contributes to modularity and ease of code maintenance. In conclusion, examples of successful application of MVI in practice are discussed, which confirms its usefulness for the development of complex and highly loaded applications.","PeriodicalId":515824,"journal":{"name":"The American Journal of Engineering and Technology","volume":"49 S3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recognizing the critical importance of addressing land degradation and promoting regeneration for climate regulation, ecosystem services, and population well-being, there is a pressing need for effective land use planning and interventions. Traditional regression approaches often fail to capture underlying drivers' complexity and nonlinearity. In response, this research investigates the efficacy of AI in monitoring, predicting, and managing deforestation and forest degradation compared to conventional methods, with a goal to bolster global forest conservation endeavors. Employing a fusion of satellite imagery analysis and machine learning algorithms, such as convolutional neural networks and predictive modelling, the study focuses on key forest regions, including the Amazon Basin, Central Africa, and Southeast Asia. Through the utilization of these AI-driven strategies, critical deforestation hotspots have been successfully identified with an accuracy surpassing 85%, markedly higher than traditional methods. This breakthrough underscores the transformative potential of AI in enhancing the precision and efficiency of forest conservation measures, offering a formidable tool for combating deforestation and degradation on a global scale.","PeriodicalId":515824,"journal":{"name":"The American Journal of Engineering and Technology","volume":"60 S8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141414256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first objective of this research is to advance our understanding of disaster resilience, particularly during the critical response period—from the onset of the disruption event to the stabilization of recovery efforts. The second objective is to translate fundamental insights gained from this understanding into practical applications. To achieve these objectives, the study encompasses various analyses. Firstly, economic losses resulting from power outages are quantified, providing insights into the broader impacts of energy disruptions. Additionally, the performance of power grid systems is evaluated to assess their resilience and effectiveness in responding to and recovering from adverse events. Furthermore, the study includes calculations for mobilization (response) time, crucial for assessing the timeliness and efficiency of emergency response efforts. Finally, the viability of employing electric bus V2G technology as an emergency power solution is thoroughly analyzed. This encompasses assessing factors such as response time, load recovery or supply, system performance pre- and post-recovery, and other resilience metrics. By integrating these multifaceted analyses, this research aims to offer comprehensive insights into the potential of electric school buses as a resilient energy solution for communities facing power disruptions.","PeriodicalId":515824,"journal":{"name":"The American Journal of Engineering and Technology","volume":"106 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140079694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Engine oil main parameters and internal combustion engines were investigated under real-world conditions for driving cycles typical for Tashkent urban environments. Three kinds of laboratory equipment and ISO standards were utilized. Our study shows that by using different types of fuel, the life cycle point of motor oil varies. Total base number (TBN), Total acid number (TAN), viscosity and flash points were taken as basic parameters of engine oil. The viscosity value of oil dominated the other characteristics.
