RR interval, which is time interval from one R wave to the next R wave, and R-peaks amplitudes from a single-channel ECG signal are employed as the input of the CNN model. We performed our experiment on single-channel ECG signal dataset and have achieved the advanced performance with overall classification accuracy of 87.9% and 97.1% on the per-segment classification and per-recording classification respectively. This model can effectively be used to detect SA from a single-channel ECG signal.","PeriodicalId":199307,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"73 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116236511","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}

For most applications, condition monitoring may not directly reflect the degree of degradation. Therefore, both condition monitoring and life data can be considered comprehensively to estimate the failure hazards as the degradation state. And proportional hazard model is one of the popular methods. The proportional hazard model considers condition monitoring data as internal covariates, and it is generally assumed that distribution parameters of the covariates are determined for the predictive maintenance model. However, the distribution parameters may be of uncertainty due to the influence of component operating conditions and sensor detection accuracy fluctuations in practical applications. Therefore, this paper proposes an extended predictive maintenance model under the covariate distribution parameters with uncertainty. For the model, the Bayesian updating method is utilized to update the time-fixed covariate distribution parameters. The Monte Carlo simulation method is used to estimate approximately the expected cost rate for the extended predictive maintenance model under various prognosis scenarios. For the simulation studies, the influence of uncertain distribution parameters for covariate is analyzed on the optimal predictive maintenance policy. The results show that the proposed model can reduce the expected maintenance cost.","PeriodicalId":199307,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123027522","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}

When the number of vehicles in the network increases, a large number of nodes send beacon periodically, resulting in channel overload and congestion. Aiming at this issue, this paper designed an algorithm based on Bayesian network to adjust transmission power. Firstly, the algorithm evaluates the current channel load based on the channel busy ratio measured by the vehicle itself. Secondly, the parameter is used to predict the channel load at the next moment through Bayesian network learning. Finally, the transmission power is adaptively adjusted based on the prediction result to avoid the network congestion. The simulation experiment shows that the algorithm can effectively reduce the transmission delay, collision rate and improve packet delivery rate.","PeriodicalId":199307,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114764037","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}
