The \"Standard Model\" is a theoretical framework that is constructed based on empirical observations and is utilized to make predictions and establish correlations with novel data. The table of elements represents a significant milestone in the field of chemistry, since it enabled researchers to make informed predictions regarding the characteristics of numerous elements and compounds that had not yet been thoroughly examined. Nonrelativistic quantum theory, as a widely accepted framework, has successfully established correlations between experimental outcomes throughout numerous investigations. Similar to its predecessors in several disciplines, the “standard model of particle physics” has exhibited remarkable efficacy in its ability to forecast a diverse array of phenomena. In a similar vein to the limitations of regular quantum mechanics in the relativistic regime, it is anticipated that the “standard model” will not hold true at infinitesimally small scales. Nevertheless, the notable achievement of the “standard model” strongly indicates that it will continue to serve as a highly accurate representation of the natural world, even at distance scales as minute as 10–18 m.","PeriodicalId":39883,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136182567","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 proliferation of data and the advent of machine learning have opened up new avenues for optimizing supply chain operations. This paper investigates the transformative impact of machine learning on supply chain management, offering a comprehensive overview of the key applications and their associated benefits and challenges.Machine learning, a subset of artificial intelligence, has become a vital tool in enhancing the efficiency and effectiveness of supply chains. Key applications include demand forecasting, inventory management, route optimization, supplier risk assessment, quality control, and warehouse management. Through the analysis of historical data and external variables, machine learning models facilitate more accurate demand forecasting, leading to optimized inventory levels and better customer service. Furthermore, machine learning empowers organizations to make data-driven decisions, optimize transportation routes, and assess supplier performance, ultimately reducing operational costs.While machine learning offers substantial advantages, it also presents challenges related to data quality, integration with existing systems, change management, and data security. This paper explores real-world case studies to exemplify successful machine learning implementations in supply chain management and discusses current trends and future prospects in the field. The integration of machine learning into supply chain management represents a paradigm shift in the way organizations make decisions, optimize processes, and respond to the ever-changing demands of the market. Embracing this transformative technology is pivotal for organizations aiming to thrive in a competitive landscape characterized by rapid innovation and customer-centricity.","PeriodicalId":39883,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136184276","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}

{"title":"Enhancing Security in Cloud Computing with Anomaly Detection Using Machine Learning","authors":"Mayank Namdev, Jayasundar S., Muhammad Babur, Deepak A. Vidhate, Santosh Yerasuri","doi":"10.52783/tjjpt.v44.i3.622","DOIUrl":"https://doi.org/10.52783/tjjpt.v44.i3.622","url":null,"abstract":"Cloud computing has become an integral part of modern business operations, offering unprecedented scalability, cost-effectiveness, and agility. However, the widespread adoption of cloud services has also raised significant security concerns. This paper addresses the imperative need for enhancing security in cloud computing environments through the application of anomaly detection techniques powered by machine learning. The ubiquity of cloud computing has ushered in a new era of digital transformation, enabling organizations to streamline operations and achieve unprecedented efficiency. Nevertheless, the dynamic nature of the cloud, coupled with the evolving threat landscape, has exposed organizations to a spectrum of security challenges. These challenges encompass data breaches, insider threats, and vulnerabilities inherent to the shared responsibility model, which necessitates a collaborative approach between cloud service providers (CSPs) and customers. Anomaly detection, a key facet of cloud security, offers a proactive and adaptive defense mechanism against a wide range of security threats. At its core, anomaly detection relies on the establishment of a baseline of normal system behavior. This baseline is constructed by analyzing historical data patterns, allowing machine learning algorithms to distinguish deviations from the expected norm. Such deviations, often indicative of security incidents or vulnerabilities, trigger alerts for timely remediation. This paper delves into the principles of anomaly detection in cloud computing environments. It discusses the shared responsibility model, the evolving threat landscape, and the need for sophisticated security measures beyond traditional tools. Key anomaly detection principles, such as baseline establishment and machine learning model selection, are elucidated. The paper explores various machine learning algorithms suitable for anomaly detection, including k-means clustering, Support Vector Machines (SVMs), and autoencoders, highlighting their unique strengths and applications in cloud security. Enhancing security in cloud computing through anomaly detection powered by machine learning is essential in safeguarding valuable data and maintaining the integrity of cloud environments. By understanding the intricacies of cloud security challenges, embracing anomaly detection principles, and implementing appropriate machine learning algorithms, organizations can proactively protect their cloud assets and fortify their defenses against emerging threats. This paper serves as a comprehensive guide for organizations striving to secure their presence in the cloud while harnessing its transformative potential.","PeriodicalId":39883,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136028136","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}
