Olipas","doi":"10.59324/ejaset.2024.2(1).01","DOIUrl":"https://doi.org/10.59324/ejaset.2024.2(1).01","url":null,"abstract":"This study aimed to conduct a needs assessment in order to design a CCTV camera placement plan in a barangay to enhance community safety and security. Employing a descriptive research design, the study involved 300 randomly selected respondents from a barangay in Talugtug, Nueva Ecija, Philippines. The results of the needs assessment underscored the importance of developing a CCTV camera placement plan for the barangay. The researcher proposed to develop a plan that aims to provide measures to improve safety and security within the community. Based on the needs assessment that has been conducted, several recommendations were drawn. Firstly, it was strongly advised to design a CCTV camera placement plan in the barangay. A follow-up study may be conducted focusing on this aspect. Future researchers must strategically place the CCTV in the area to optimize its full potential for securing the community. Secondly, community engagement and collaboration were highlighted as crucial factors for successful implementation, emphasizing the importance of involving community members, stakeholders, and educational institutions in the planning process. Thus, when designing a strategic CCTV placement plan, the involvement of various stakeholders is highly encouraged. Further, allocating resources for installation, maintenance, and monitoring was also proposed to ensure the sustainability and effectiveness of the surveillance system. Lastly, continuous evaluation and improvement of the CCTV camera placement plan when implemented is highly recommended, emphasizing the need for regular reviews, resident feedback, and performance monitoring to optimize the system's functionality. These recommendations provide valuable guidance for barangay officials in their pursuit of enhanced safety and security. By implementing the proposed plan that may be developed through this study and considering the input of the community, the barangay can create a safer environment and promote a sense of security among its residents.","PeriodicalId":517802,"journal":{"name":"European Journal of Applied Science, Engineering and Technology","volume":"183 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140523436","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}

Aiming at the problem that the traditional ARIMA model has poor performance in predicting passenger flow, a hybrid prediction method based on ARIMA-Kalman filtering is proposed. In this regard, ARIMA model training experimental samples are integrated with Kalman filter to create a prediction recursion equation, which is then utilized to estimate passenger flow. The simulation experiment results based on the inbound passenger flow data of Nanjing metro station show that compared with the single ARIMA model, the root mean square error of the prediction results of the proposed ARIMA-Kalman filter hybrid algorithm is reduced by 257.106, and the mean absolute error decreased by 145. 675, the mean absolute percentage error dropped by 5. 655%, proving that the proposed hybrid algorithm has higher prediction accuracy.

This is because we must understand the fluid's overall behavior from the reservoir to the production and processing facilities, and ultimately to the refinery. Modern computer software that uses equation of state (EOS) models to simulate experiments and illustrate fluid phase characteristics has contributed to its growth as a distinct field of study. To find the operating parameters that will maximize the surface liquid content and prolong the production plateau duration at the lowest feasible cost, PVT simulations are run. These simulations employ laboratory-derived data to fine-tune the EOS models, with the outcomes being integrated into reservoir simulation and research. The quality of the data is crucial to getting a good match between EOS and laboratory data, and for retrograde gas condensates, this can be particularly difficult because of their complex phase behavior. When utilized in reservoir simulations, an inadequate match leads to computational mistakes and unrepresentative findings, endangering the reservoir management decisions that depend on it.","PeriodicalId":517802,"journal":{"name":"European Journal of Applied Science, Engineering and Technology","volume":"2018 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140516136","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}
