Firstly, the motion models of the wave and the ship's rolling and anti-rolling are established. The vector propeller anti-rolling device is then designed based on these motion models, and its structural design, attitude sensing module and control system are briefly described. And the propeller performance is also analyzed to make the anti-rolling torque generated by the device more accurate. On this basis, a laboratory experiment based on ship model was carried out, using a moving slider mounted on the ship model to simulate the rolling effect under regular waves. The average anti-rolling effect under laboratory conditions can reach 80%. In addition, the real ship experiment at sea was further carried out. The average anti-rolling effect can reach 50%. Although the anti-rolling effect of real ship experiment at sea is reduced, it can still meet the ship comfort standard. Consequently, the experimental results show that the proposed anti-rolling device has a good practical value.","PeriodicalId":208108,"journal":{"name":"2021 International Conference of Social Computing and Digital Economy (ICSCDE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129707686","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}

However, since people began to collect LST data purposefully, they have been plagued by the problem of missing data. In recent years, with the development of satellite remote sensing technology, the quality of LST data has been continuously improved. However, due to the limited resolution of the sensor and the complex atmospheric environment, the problem of missing data still occurs in the LST data, and the accuracy and effectiveness of the data are therefore greatly reduced. In this article, we propose a LST data reconstruction method based on deep learning network, and use this method to reconstruct the 9-year (2000–2008) MODIS LST map. In the comparative experiment of selected regions, the ratio of “high-quality” pixels that can be collected in the reconstructed data is between 32% and 41.5%. Compared with traditional methods, the ratio of “high-quality” pixels that can be collected is increased by 10% to 20%, which greatly improves the use value of massive satellite data. Experiments also show that the use of different loss functions will also affect the reconstruction effect of the method.","PeriodicalId":208108,"journal":{"name":"2021 International Conference of Social Computing and Digital Economy (ICSCDE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133166198","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 analysis of suspension state, virtual accumulation state and actual accumulation state of concrete solid particles, combined with the characteristic particle sizes of large particles and small particles, the packing density and constraint conditions of concrete solid particles are calculated. Based on the structure of BP neural network, the input of hidden layer is calculated, and the output of hidden layer is calculated according to s function. By comparing the expected output with the actual output, the threshold and weight of BP neural network are modified to construct the optimal ratio parameters of steel fiber reinforced concrete. The experimental results show that under the same experimental environment, the flexural strength of concrete is the best under the ratio parameters extracted by this method, and the extraction accuracy of the best ratio parameters is the highest, so this method can improve the rationality of the ratio of steel fiber reinforced concrete.","PeriodicalId":208108,"journal":{"name":"2021 International Conference of Social Computing and Digital Economy (ICSCDE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132358824","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}
