SK-AOR380 plays a role to reduce the probability of lightning strike by increasing electric field concentration between SK-AOR380 shade and ionizer, besides electric field at the lightning rod tip part is relieved. In other words, the corona dischrage is early initiated before lightning strike due to early generation of ionized free electrons between SK-AOR380 shade and ionizer by accumulating the induced charge from charged clouds with opposite polarity. To analyze charge behaviors, we considered fully coupled numerical model based on the charge continuity equations for positively charged ion, negatively charged ion and electrons. The results revealed that the SK-AOR380 creates a non-uniform electric field distribution with a large field enhancement causing ionization to initiate corona discharge under 300 kV lightning impulse voltage. This result is expected that the probability of direct lightning strike can be reduced by improved lightning protection rod.","PeriodicalId":282635,"journal":{"name":"2022 IEEE 4th Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"302 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123059071","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}

Firstly, video analysis and action decomposition of the current situation of the operation procedure of die-lip finishing turning are conducted, and it is found that the operation process is unreasonable and the action posture is not standardized; secondly, the action is evaluated by simulation analysis based on RULA and NIOSH analysis method in DELMIA, and it is found that the labor load of workers is high and the comfort is low, and there is a risk of damage; finally, the ergonomics and MTMUAS methods are used to optimize the die-lip finishing turning. Finally, the ergonomics and MTM-UAS methods were used to optimize the operation process and formulate standard working hours, and the perfected action was evaluated by simulation again. Comparing the before and after analysis and evaluation results, we obtain that the utilization rate of workers increased from 43.8 to 49.9%, and the utilization rate of machines and equipment increased from 54.7 to 62.3%.

Especially, the occurrence of major news events increases the number of news vocabulary (e.g., new professional terms). However, the existing vocabulary textbooks, limited by the publishing cycle, are designed with limited English word resources. In addition, to meet the vocabulary learning demands of different user groups, English word-learning software relies on professional vocabulary books for users to practice vocabulary repeatedly. This hinders the users who rely on memorizing software from using the vocabulary in business communication or academic writing. In this context, this study proposed the design framework of the intelligent vocabulary recommendation and learning model for college English. The overall design strategy of the model is first analyzed, and the system design mechanism of the model is articulated. This system presented the design elements and mechanism of the personalized learning system of college English vocabulary. The results of this study provide customized English vocabulary resources for college English learners with different needs, interest characteristics, and starting abilities.","PeriodicalId":282635,"journal":{"name":"2022 IEEE 4th Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127300900","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}

To detect PVC accurately, the features should not only be chosen properly but also be determined precisely. Therefore, the following ways are adopted to improve the performance of PCV detection. Since many features for PVC detection are related to the amplitudes and locations of P, Q, R, S, and T points, we apply inverse-gradient weight functions to extract the baseline precisely and determine their amplitudes more accurately. Second, a location estimation mechanism is adopted to determine their locations precisely. Moreover, instead of PR intervals, QT intervals, and ST segments, which are hard to measure precisely, the distances among Q, R, and S points are adopted. Furthermore, the existences of P and T waves, the local and sub-global RR interval ratios, and a product-form score function are also applied for PVC determination. Simulations for the MIT-BIH Arrhythmia dataset show that the proposed algorithm achieves a sensitivity of 98.079% and a specificity of 99.306%. The proposed algorithm applies only 8 features but can achieve a very good performance.","PeriodicalId":282635,"journal":{"name":"2022 IEEE 4th Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123303190","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}

Prototypical bladed-disk structures subjected to finite-element simulation and modal testing show the presence of specific wavenumbers over the base number of nodal diameters that contaminate and continue to degrade the appearance of some doublet modes. In light of a companion perturbation analysis for periodic structures, it is explained how the natural frequency and wavenumber content of such modes varies and splits. Simultaneous measurements with a modal test setup positioned over the structure are used to establish and validate resonance conditions. The findings demonstrate that the highest split of double natural frequencies of each modal family occurs at frequency-veering regions where there are such regions. Along with the response amplitude and polluted wavenumbers, the lower harmonics of the split mode show the area of localized stiffness.","PeriodicalId":282635,"journal":{"name":"2022 IEEE 4th Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114919248","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}

Thus, accurate solar power forecasting helps system operators reduce the risk and cost of generator scheduling. Compared to wind power forecasting, solar power forecasting has a higher challenge because the prediction of solar irradiance is difficult. However, the curve of solar irradiance includes a daily pattern. Thus, statistical methods or deep learning models capture the important characteristics of solar power generation, which improves forecasting accuracy. This study summarizes essential issues about solar power forecasting, including potential training models, data processing, efficient weather classification, and other corresponding technologies.

However, the mobility of multicast sources is rarely discussed. We present an enhanced multicast protocol, which extends from the Multicast Listener Discovery (MLD) protocol, named Light Load Multicast (LLM), in the NEMO environment. The LLM is considered the alternative MLD to maintain the multicast tree in the NEMO. The LLM has two benefits. The reconstruction mechanism handles the mobility of the multicast source by reconstructing the multicast tree. The multigroup suppression mechanism curbs the multicast tree maintenance cost for the mobility of the multicast members.
