Premature beats need to be judged by the connection between beats, and only using CNN model will cause low sensitivity. In this paper, a model combining CNN and LSTM was proposed. CNN extracted local features and LSTM captured the dependence relationship between heart beats before and after, realizing the recognition of 15 arrhythmias with an accuracy of 98.15% and sensitivity of all arrhythmias above 90%.

Based on the dynamic model, taking the planar four-link mechanism as the research object, the influence of position and quantity of clearance on acceleration and penetration depth of clearance joint are studied by using ADAMS simulation software. Taking the mean square deviation of rocker acceleration as the quantitative analysis index, all cases of clearance are analyzed quantitatively. The results show that clearance has a great influence on the acceleration of the mechanism. After the system is stabilized, the number and position of clearances will not change the motion state of the journal, and journal and bearing are always in contact. In the case of single clearance, the clearance joint closest to the motor position has the greatest influence on the dynamic response of the mechanism. There are complex coupling effects between multi-clearance joints, and the number of clearances is not the only factor affecting the dynamic performance of the mechanism.

In the study, the result of the alternating current (AC) power flow was input into the system, and then the loss of each subcircuit was equivalent to the virtual power supply or load. Next, a flexible and adjustable network loss distribution coefficient was introduced and the fair current tracing method was combined with the counter current tracing method to establish the bidirectional allocation model of the network loss carbon flow. Given that the hidden carbon emissions were caused by the deviation between the load and the power of the new energy, the new energy generating units were treated as loads, and the real-time power network was decomposed into the day-ahead planning power network and the real-time power deviation network for the power flow tracing and the carbon flow calculation, which solved problems such as: the hidden carbon flow was unevenly allocated and the carbon reduction contribution of the new energy units cannot be quantified. A 4-node system was used for the test, and the test results proved the correctness and effectiveness of the proposed method.","PeriodicalId":360004,"journal":{"name":"2021 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132267866","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}
