Some commercial Finite Element Method (FEM) software, such as ANSYS and COMSOL, can be used for calculating this coupling field matter. These software encapsulate solver libraries based on standard mathematical equations of electric field, thermal field and solid field, and provide coupling interface between them. However, for unusual and more complex physical fields coupling problems, whose mathematical equations are different from the standard equations, hence the commercial FEM software are hardly to get accurate calculation results. This paper proposes a new solution and more convenient method based on Finite Element Language And it’s Compiler (FELAC) for experienced professionals and researchers to deal with this solution. Firstly, the modified mathematical equations should be established. Then the weak form of equations and FELAC script files can be written directly. The FELAC will automatically generates the FEM calculation program and display simulation results. In this paper, a typical Electric-Thermal-Solid coupling analysis model is introduced as an demonstration, of which the weak form is deduced to write finite element files, and the project is established in FELAC for analysis. The simulation results are compared with COMSOL to verify the correctness of calculation.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116917011","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 components of railway structure are likely to be air-slaked or breached while the metro system is running. Till now the essential components maintaining is mostly done by human, and this costs time and human resources. CNN has high accuracy on object detection but may not be able to locate the minor damage happened on railway structure components. In this study, a Swin Transformer based method is introduced for components diagnosis in railway system, which can detect and segment the target object, even they are sometimes small and indistinguishable for human eyes.

In this paper, the calibration source is designed for human body temperature measurement calibration. So, the calibration source should have the close to 1 emissivity in 12-18GHz and have good temperature uniformity. To achieve the above two requirements, a small and high-precision and temperature controllable blackbody calibration device is designed. In this paper, the electromagnetic scattering characteristics and temperature distribution uniformity of blackbody calibration source is analyzed. The cone model design is determined by simulation. During the simulation, it is found that increasing the coating thickness does not significantly improve the emissivity under small-scale and large elevation. Finally, a calibration source is realized. Under the working frequency band, the emissivity is higher than 0.998. And the maximum surface temperature distribution error is only $2 ^{circ}mathrm{C}$ in $100 ^{circ}mathrm{C}$ situations.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130711160","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}

Theoretical analysis shown that the increased asymmetric capacitive coupling effect between data and pixel electrode signals is the main reason for CCT of the high transmittance panels. If applying some traditional strategies to improve CCT under the line-inversion driving scheme, the effectiveness is very limited and there is a loss of transmittance. When using the proposed sup-flip driving scheme, good image quality with weak CCT can be obtained in the color images. This is mainly ascribed to the dot inversion driving mode of pixel signals, which greatly weakens the coupling effect caused by the change of data signals and balances the brightness difference between adjacent pixels. These results demonstrate that applying the proposed super flip driving scheme is an effective way to modulate the CCT defect and enhance the display performance for TFT-LCDs with high transmittance design.","PeriodicalId":166358,"journal":{"name":"2022 IEEE 5th International Conference on Electronics Technology (ICET)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132684450","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}
