In recent years, the number of primary and secondary schools in China has grown rapidly. As the energy use of school buildings is different from the energy use of other building types, it is important to explore the adaptability of different CO2 emission reduction technologies to primary and secondary school buildings. This study investigated the basic information of 31 primary and secondary school buildings in a hot-summer and cold-winter area in China and obtained energy consumption data from 21 of them. The 21 schools were then divided into two typical school building types through cluster analysis, and typical models of the two typical building types were built using the Designbuilder software. A total of 22 CO2 emission reduction technologies were selected from practical building cases and from local regulations on the three dimensions of such technologies (i.e., improving the thermal performance of the building envelope, renewable-energy utilization, and use of high-performance equipment) and were applied to the simulation to obtain their corresponding CO2 emission reduction rates. Finally, the 22 CO2 emission reduction technologies were divided into three different grades according to their CO2 emission reduction rates to provide architects with a theoretical basis and practical reference for selecting the appropriate and optimal CO2 emission reduction technologies in the architectural design stage, and to promote the construction of green and low-CO2 campuses.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132005708","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}

It's a challenge that transmission line foreign object detection achieves real-time on edge calculation as well as high performance. This paper proposes an object detector with both speed and accuracy based on YOLOv5, named YOLOv5-GHK. First, replacing Convolution, Ghost module has less parameters and calculation to achieve real-time speed. Then, network prediction with high-resolution feature improves accuracy of small transmission line foreign objects. Last, knowledge distillation ensures that lightweight model has less loss of precision. As a consequence, the proposed method runs at 36 FPS on NPU with a state-of-the-art accuracy.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115087286","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}

The pull-out test of specimens subjected to different temperatures and constant temperature time is carried out to explore their damage mode and high temperature damage mechanism, analyze the effects of different temperatures and constant temperature time on their tensile load capacity, and establish the calculation formula of tensile properties of chemical anchor bolt groups. The research results showed that the specimens were not subjected to high temperature had concrete cone failure, and the specimens were subjected to high temperature had concrete mixed failure or splitting failure. High temperature damage is the result of the combined action of the chemical anchor bolt and the substrate concrete. The discounting effect of temperature on the tensile properties of chemical anchor bolt groups specimens is obvious, while the effect of constant temperature time on the tensile properties of chemical anchor bolt groups specimens is small. The calculation results of the established tensile properties formula basically match with the test results.","PeriodicalId":355388,"journal":{"name":"Proceedings of the 2022 International Conference on Computational Infrastructure and Urban Planning","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133852873","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}
