The assessment, planning, and design of deep excavation construction, earth retaining methods, and ground improvement influence the duration, cost, safety, and risk of the subsequent foundation excavation. The purpose of this research is to develop an assessment framework to select the proper method of deep excavation construction in building construction to ensure safe, fast, and economic excavation. Through literature reviews and expert interviews, the criteria and the sub-criteria in the initial assessment framework were determined. Afterward, the Delphi method was used to finalize the assessment framework. The final assessment framework consisted of five criteria and 25 factors. a deep excavation construction method scoring table was established by using Analytic Hierarchical Process to determine the relative weights of the criteria and the sub-criteria and easily apply the assessment framework to deep excavation projects. Finally, a study case was presented to show how to use the scoring table to select a proper construction method.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128269494","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 accidents usually occur when the protection facility fails to function due to management failure. As a result, safety monitoring plays an important role in preventing construction accidents. This study presents a visual-based method with a specialized label to be recognized effectively by computer visualization technique. The falling protection by the sudden opening of an elevator on the construction site was selected for the case study. A Faster R-CNN deep learning model was adopted for the proposed visual-based safety monitoring method. According to the testing results on a real construction site, the proposed method achieved the rates of 00% of clearness rate and 98.0% of correctness. Moreover, the proposed method required only a specialized water-proof identification tag (ID-tag) and the regular Closed-Circuit Television (CCTV), which is precise, effective, and cost-effective than other advanced methods available nowadays. The proposed method allows practical applications in the safety management of construction sites.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129649938","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 threshold voltage VT of the TIOHOS device increased after UV radiation, which has a relationship to UV TD. The TIOHOS with TiN/ITO double gate reduced the gate UV absorption coefficient more than TiN and the gate electric resistivity more than ITO. The TIOHOS device with TiN/ITO double gate successfully increased the performance of a nonvolatile UV TD sensor which is better than that of titanium nitride–silicon oxide–hafnium oxide–silicon oxide–silicon device TOHOS (with TiN gate) and indium tin oxide –silicon oxide–hafnium oxide–silicon oxide–silicon IOHOS (with ITO gate). To eliminate the UV TD information in the TIOHOS UV TD sensor and let the UV TD become a natural invalid state, positive charges were injected by applying a negative bias on the control gate (NBS). It is proved that the TIOHOS with TiN/ITO double gate was appropriate for nonvolatile UV TD radiation sensors.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134164882","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 system includes three units of the transmission mechanism, identification host, and database. The transmission mechanism transports fruits to the bottom of the camera for grading; the identification host uses STM32F746 as the core and integrates the OV9655 and other peripherals to locate the fruits on the transport mechanism for classification. Through the above integration, the automation of fruit grading can be improved, and the impact of the aging agricultural population can be reduced.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129257137","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}
