Firstly, point cloud data and image data are acquired by different data acquisition methods. Laser point cloud and oblique image are fused by installation parameters so that geometric elements are consistent and benchmark is unified. Processing level is not limited to element level only, so as to ensure the integrity of information, and the fused mutual information remains consistent in scale, texture and direction. Secondly, under the condition of space-time synchronization, the relationship between point cloud and image in geometric space is established, and the alternating \"energy transfer\" is used for shape prediction and visual filling by matching under texture mapping constraints to enhance the semantic information of the 3D scene. Finally, a 3D building information model is established. Using the experimental results to track the whole life cycle (design, construction, operation) in real time saves the cost of building rework, reduces the building cycle, and improves the building accuracy. Especially based on BIM during Novel Coronavirus Pneumonia: analyze hospital space resource management and elastic function; construct medical unit model of infectious disease hospital; simulate and optimize medical process in infectious disease hospital; rapidly construct prefabricated infectious disease emergency hospital; simulate hospital infection path and dynamics; the auxiliary design and construction of infectious disease treatment in existing hospitals; The monitoring analysis and automatic control of hospital infection safety operation.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"139 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85241075","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}

Methods: Personnel are divided into two batches by region. Adopt a diversified training model to train all personnel, finally conduct practical assessments and issue certificates. Collect information through information technology, analyze questionnaires, and understand trainees’ circumstances before and after the training. Each training batch has uniform teachers and the same training methods. Results: After the training, the trainees' proficiency in putting on and taking off protective equipment increased by 22.85%, and ability to choose protective equipment according to different working environments increased by 22.04%; 78.23% trainees believed that practical exercises should be emphasized. Taking off protective clothing was considered as the most difficult link in practical training (91.13%), followed by putting on protective clothing (70.43%). 96.24% trainees believed that this training is helpful for future work. Conclusions: It is quite necessary to implement personal protective equipment training among new hospital infection managers; where, practical training, assessment, information-based questionnaire survey, expert theory teaching have achieved good results; the training helps reduce occupational exposure-induced hospital infection, and at the same time, avoids improper use of protective materials and waste.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87047835","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}

Based on the willingness and influencing factors of new professional farmers to participate in skill training in the development of modern urban agriculture, this study seeks to study the education of professional farmers from the perspective of demand. Methods: Based on the questionnaire survey data of new vocational farmers in Wenzhou, this study systematically analyzed the current situation, training willingness, training methods, and training effect of new vocational training, and made quantitative statistical analysis of the original basic data. Combined with the characteristics of agricultural industry and post, this study empirically analyzed their perception of participating in skill training and the influencing factors. Results: The number of new vocational farmers willing to participate in training was significantly higher than that of farmers unwilling to participate in training. The frequency of technical problems encountered in agricultural production, the times of training, the evaluation of training effect, effect, cost, teacher level, hardware level, certificate, and other factors have a significant impact on the willingness of new vocational farmers to participate in skills training. Conclusion: This study proposes to build a vocational occupation education system to enhance the training intention of new occupation farmers.

In the process of detecting IGBT single tube noise, thermal noise and shot noise show obvious white noise characteristics in the low frequency band, which are detected under the background of strong white noise 1/f noise can characterize the performance of IGBT devices. Therefore, on the basis of the Time-Frequency Peak Filtering (TFPF) algorithm, a two-dimensional time-domain adaptive T-ATFPF algorithm is proposed, and the adaptive segmentation is realized by means of the confidence interval crossing criterion based on Chebyshev’s inequality. Variable window length,use a small window length to process the signal section, which retains more detailed information of the effective signal.Use a larger window length to process the buffer section to ensure a smooth transition.Use the large window length to process the noise section, which more effectively suppresses randomness for noise, apply T-ATFPF to artificial synthesis model and actual model. Experimental results indicate that compared with the conventional algorithm, the improved method can better recover 1/f noise, and the ratio of signal to noise is greatly improved by about 1.3dB.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77552833","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 paper chooses JXTA development platform to build P2P network, and then constructs SIP soft terminal on it. Firstly, it introduces the background knowledge, related research, P2P network technology, JXTA technology and SIP protocol. Then, the feasibility of p2p sip system is analyzed, including the combination of P2P and sip, network structure and framework structure. Then the routing mechanism of JXTA is deeply studied, including distributed index of shared resources, limited range traversal, dynamic view of sink node and loose and consistent distributed hash table (DHT). At the same time, this paper proposes an improvement strategy to overcome the shortcomings of JXTA routing mechanism such as limited range traversal and loose consistent DHT, that is, introducing the chord ring of consistent hash algorithm in the aggregation network layer. Based on the in-depth study of JXTA structured network and SIP protocol, a P2P SIP system is designed and implemented. The experimental results show that the system can maintain normal SIP communication without maintaining the central server.","PeriodicalId":10707,"journal":{"name":"CONVERTER","volume":"86 14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84007847","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}
