The most widely used piezoelectric materials mostly use the inverse piezoelectric effect. According to the positive piezoelectric effect of piezoelectric materials, it is an important research direction to try to use mechanical vibration as the exciting force to excite piezoelectric materials to generate electric energy. The research mainly focuses on the following three aspects: piezoelectric materials, the fixing and exciting methods of piezoelectric sheets, energy processing circuit and management This paper reviews these three aspects.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114946022","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}

Modeling the spatiotemporal information of dynamic scenes in videos is the main challenge of the task. To solve this problem, this paper proposed a spatiotemporal residual network model based on ResNeXt. Our model uses the 2D deep convolutional network for spatial information extraction, and the residual units of ResNeXt are transformed to spacetime to increase the network’s temporal receptive field making it possible to extract temporal features in videos. In addition, to improve the generalization ability and prevent overfitting, we extend the global pooling strategy from spatial to temporal. On both of the static and moving subsets of the YUP++ dataset, the classification accuracies are improved compared with state-of-the-art methods, which indicates that our optimized method could make better use of spatiotemporal information for dynamic scene recognition.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121205344","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}

All kinds of data and information are popping up and flooding people’s lives. To better manage this data and find the content you need in an information explosion environment, you need to apply cloud computing technology. Based on cloud computing and mobile Internet technology, this paper adopts the method of data mining, according to the characteristics of public opinion analysis system, and combines serial K-NN algorithm to design the parallel K-NN algorithm with the following ideas. Experimental data show that the content in the text library is filtered and contains the text of the crawling web page. The experimental results show that, in order to test the performance of k-NN algorithm, three test samples are constructed in this experiment, with the sample sizes of 5G, 10G and 15G respectively, and the information training sets of 2000 and 3000 respectively. In 5000, 6000; for 8000 and 10000 samples, the time cost of training is compared with the time cost of traditional serial mode. In view of the current mobile Internet information presents the characteristics of large data volume, complex data structure and diverse data content, in order to carry out information mining, the basic process of information mining should be clarified first, and then the corresponding mining technology should be used to realize effective information mining.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125366433","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 measured points are projected to the reference coordinate, the systematic error of the measured points can be amplified when the reference points have large errors or there has a large distance between the reference points and the measured point.

Elastic strain, thermal strain, elastic strain caused by phase transformation, plastic strain and plastic strain induced by phase transformation are fully considered. The newly developed model was used to simulate the numerical changes of temperature, phase transformation, stress / strain and warpage along the thickness direction of low carbon bainitic steel under three cooling modes, and the influencing factors of warpage were analyzed quantitatively. The results show that the temperature difference and phase transformation are uneven in the thickness direction of the steel plate during asymmetric cooling, and the stress / strain asymmetry is the main factor affecting the warpage.
