The continuous development of the media has drawn it closer to sports, and television broadcasting is an important facilitator in making sports events widely popular among people.The sports of table tennis require the use of a small court and a small ball played in a fast speed with strong rotation and variable landing points. These characteristics also lead to some limitations, which may greatly reduce audiences’ sense of immersion, experience and participation in events; and the screen design of television broadcast becomes very important. Therefore, this study takes the 2022 National Intercollegiate Athletic Games as a case study to analyze its broadcast screen design, hoping to provide suggestions on the screen design for similar sports events broadcasted in the future.","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80546331","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 studied DCMG comprises an equivalent aggregated (EA) SF and an EA WF based on permanent-magnet synchronous generator (PMSG). The AC output of the EA WF is transformed to a DC quantity through an EA voltage-source converter (VSC), which is integrated with the DC output of the EA DC-DC converter of the EA SF. The DC quantity of the DCMG is transformed to an AC quantity to send to an AC power grid through an EA voltage-source inverter (VSI), a step-up power transformer, and transmission lines. Small-signal stability of the studied DCMG under various chosen operating points is achieved using eigenvalue analysis. Dynamic simulations and transient responses of the studied DCMG under various disturbances are also completed and evaluated.","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77756303","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 testing cases are generated by fuzzing testing methods according to the HDLC specifications. The CTT 3.1 is used as the client sending requests to the smart meter server.

Scanning electronic microscopy confirmed the thicknesses of Au layers and revealed many typical hexagonal micro-nano pits distributing on the surface.

The research idea came from EVs as well as the increasingly mature wireless charging technology in recent years. This paper analyzes the possibility of using the radar system combined with image recognition to solve the problems when vehicles are currently charged at fixed positions. Vehicles sometimes cannot be accurately aligned with the power transmission board, resulting in poor efficiency, or there is insufficient power transmission board due to locations. This paper provides solutions to improve charging efficiency, using radar as a sensor in design to find the position of the vehicle and position it below the power receiving place. The image recognition module PIXY 2 is also employed to capture the image color to adjust a more accurate position, so that the charging efficiency and speed can be improved and that time and space limitation can be avoided.","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87508291","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}
