Because the overall lateral stiffness of the structure decreases as a result of soil flexibility, the lateral natural period lengthens. The building frames situated on the Raft foundation may experience a significant change in seismic response due to this extension of the lateral natural period (T). Therefore, it is imperative to consider the soil's flexibility, also known as soil structure interaction, when doing analysis on the foundation's supporting layer. \u0000This paper examines how asymmetric building frames with raft footings behave dynamically when subjected to seismic forces that involve soil-structure interaction. The analysis is performed with SAP 2000*V21 FEM software. The structure is idealized as a three-dimensional space frame, with slabs modeled as a thin shell with four noded plate elements and six degrees of freedom at each node, and beams and columns modeled as two noded line elements. The soil is represented as equivalent springs with one (Winkler) and six (Modified Winkler) degrees of freedom; the stiffness of these springs varies depending on the type of soil and is determined by its dynamic shear modulus and poissons ratio. The Modified Winkler and Winkler raft foundations are modeled as thin shells with four noded plate elements, each with six degrees of freedom, and are criticized so that the element aspect ratios are equal to one. \u0000  \u0000To assess the impact of soil structure interaction on building frames, the response is compared for a range of building frames with and without consideration of soil flexibility in terms of fundamental Natural Period, Seismic Base Shear, and Max. Lateral Displacement. The parametric study for Zone V takes into account the influence of various parameters, including the number of bays, stories, span lengths, and soil types (i.e., soft, medium, and stiff). \u0000  \u0000It is discovered that the fundamental lateral natural period and seismic base shear of the system are significantly altered by the influence of soil flexibility on building frames. As soil stiffness decreases, the lateral natural period and seismic base shear increase as a result of soil flexibility. Additionally, it has been noted that as the number of bays increases, so do the building's base shear and lateral period. As the number of bays and stories increases, so does the maximum lateral displacement.   \u0000 ","PeriodicalId":515233,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"79 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139611217","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}

While numerous research journals delve into the wear resistance of Compacted Graphite Iron (CGI) materials, there is a notable gap in understanding the correlation between Austempering temperature and abrasion properties. Material wear is influenced by various factors within the application environment, broadly categorized as time, load, and speed.

However, identifying ideal processes for RPA implementation can be challenging. Process Mining is a strategy that leverages User Interface (UI) logs to delve into processes and generate \"process maps.\" These logs record user actions during processes, necessitating the use of a tool   such as UI Action Logger to capture and transmit them to a cloud-based application for logging. Subsequently, Process Mining frameworks like ProM utilize these logs to construct process models, aiding in the identification of repetitive processes suitable for RPA automation. This innovative study shifts the focus of process mining from event logs to UI logs, simplifying the detection of potential routines. Enriched UI logs are valuable for creating RPA bots, conducting in-depth process analysis, task mining, and training RPA bots through machine learning, and selecting processes for automation. In summary, UI Action Logger offers distinctive features, capturing user interactions at a coarse level conducive to RPA implementation.","PeriodicalId":515233,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140506867","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}

A customer is free to abandon the system after receiving service in the first of  k stages (k > 1). There is a specific order to the stages, starting with the first stage service and continuing on to the second stage service and so on. The customer has multiple opportunities for subsequent service after each phase. However, the re service can only be used from the very beginning, so it doesn't matter which stage he left. Therefore, the customer who requires a different service should go to the very end of the line and wait there.

These questions of fact are usually associated with accidents, crimes, catastrophic events, property degradation, and various types of failures. This research discusses a serious incident that occurred on a Boeing 737-300F aircraft operated by The XYZ airline which operates unscheduled domestic flights in Indonesia, with a flight route from Jakarta Soekarno International Airport (CGK) to Samsoedin Noor International Airport Banjarmasin (BDJ). When the plane was about to land, and the pilot operated the flaps from the 30o position to the 40o position, there was an asymmetry between the left and right flap trailing edges of more than 20o, which caused the plane to become unstable because it rolled to the left, and the pilot was unable to control the plane when landing, which causing a serious incident on the plane. This research aims to find the root cause of trailing edge flap asymmetry of more than 20o as an evaluation for companies in determining and implementing corrective and preventive actions so that this problem does not happen again in the future. This research will use forensic engineering investigation methods and carry out chemical composition testing (Optical Emission Spectroscopy); metallographic testing (micro and macro structure observations); FESEM testing and microchemical composition testing (EDS); and hardness testing. Then for each test result an analysis is carried out based on scientific knowledge. The results of the investigative analysis were to find the root cause of the trailing edge flap asymmetry problem of more than 20o. After getting the root cause of each method, the author then compares the results of one method with another method to draw conclusions to consider and determine corrective and preventive actions to be taken and implemented in the company or organization.","PeriodicalId":515233,"journal":{"name":"Tuijin Jishu/Journal of Propulsion Technology","volume":"104 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139630330","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}
