{"title":"An Optimized Hybrid ARIMA-GARCH Model Application on RR Interval Time Series Prediction for Heart Disease","authors":"Sicheng Shu","doi":"10.61173/frjpde45","DOIUrl":"https://doi.org/10.61173/frjpde45","url":null,"abstract":"Heart disease is one of the highest mortality rate diseases worldwide, with arrhythmias frequently serving as a trigger (such as cardiomyopathy) or a complication (such as coronary heart disease) for cardiovascular diseases. Therefore, it is crucial to monitor abnormalities in heart function through the early identification of deviations in heart rate variability (HRV). In modern medical systems, wearable real-time monitoring devices and artificial intelligence are commonly employed to generate electrocardiograms (ECGs) and analyze HRV data. The key to this application lies in making reasonable judgments of HRV data using data mining tools, including multiple linear regression, support vector machine, random forest, or long-short-term memory neural networks. However, these models fail to yield satisfactory results for cardiac rhythm monitoring. Consequently, the paper introduces an optimized hybrid ARIMA-GARCH model to enable heart disease detection and pathological diagnosis, playing a guiding role in personalized treatment and the tracking of the cardiovascular health status of monitored individuals. The proposed model combines data preprocessing using the one-sided Hodrick Prescott filter and parameter tuning based on partitioning-interpolation techniques and Fast Discrete Fourier Transform to fit and predict the RR interval time series. Experimental results indicate that our proposed model exhibits significant advantages in quantitative assessments compared to other models, as it effectively preserves the trend and accounts for high volatility in short-term forward prediction.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"28 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141379030","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 vehicle is equipped with both wired and wireless charging capabilities. However, the latter requires a larger area, which restricts the number of charging opportunities and is incompatible with the growing demand for charging. Consequently, wireless charging will become the dominant method of charging electric vehicles in the future. This study will provide a comprehensive comparison of five main radio power transmission methods, with a particular focus on the in-depth analysis of ICPT and MCRPT systems. It will also discuss strategies to improve the efficiency of the magnetic coupling mechanism and cope with power fluctuations in dynamic charging. Additionally, different power supply modes will be evaluated, with particular emphasis on the efficiency, stability, and cost-effectiveness of the compensated rail supply mode. Finally, this study sought to identify the key research areas for the advancement of wireless charging technology for new energy electric vehicles. It also highlighted the areas that require particular attention in future research.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"102 4‐7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381300","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}

This surge underscores the necessity for accessible, well-organized tourist information. Given the vast number and broad distribution of tourist sites, intelligent filtering and visualization of these locations are crucial. This paper introduces Tour Enhance, an interactive system designed to dynamically exchange information between the system and its users. Unlike traditional static methods, Tour Enhance utilizes real-time processing to tailor travel recommendations to individual user preferences, thereby improving user engagement and satisfaction. This study undertakes three key tasks: statistical analysis and visualization of tourist data, rule-based recommendation generation, and user survey-based evaluation of these recommendations. The effectiveness of Tour Enhance was assessed through a user study with 57 participants, who highly rated the system on interface usability, functionality, and accuracy of recommendations. The results demonstrate that Tour Enhance effectively enhances the travel planning process, highlighting the significant advantages of integrating interactive systems and personalized data visualization in tourism. This research contributes to the advancement of human-computer interaction applications in tourism and lays the groundwork for future studies focused on enhancing user experiences through technological innovations.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"111 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377056","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}

REM sleep is crucial for memory consolidation and learning. It also supports physical recovery and promotes cell regeneration, neurotransmitter transmission, and immune function. The regulating function of REM sleep remains ambiguous despite numerous advancements in its investigation. The absence of neurotransmitter receptors reduces REM sleep, and altered environmental conditions have a corresponding effect on REM sleep. This study summarized how REM sleep interacts with hormones, neurotransmitters, and gene expression. The study found novel properties of REM sleep, explored the connection between cognitive and emotional functions with REM sleep. REM sleep is a stage of increased brain activity, and the study of REM sleep helps us to better understand brain function and neural activity. Examining REM sleep allows for a thorough exploration of the brain’s operational processes, offering valuable insights for neuroscience research. Further study on REM sleep in the future could focus on impact of sleep on body and brain processes, leading to a better comprehension of treating sleep disorders and advancing cognitive neuroscience.","PeriodicalId":438278,"journal":{"name":"Science and Technology of Engineering, Chemistry and Environmental Protection","volume":"112 S1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141377798","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}
