With the rapid development of new energy electric vehicles (EVs) and the continuous advancement of wireless charging technology, high-power wireless charging technology for EVs has garnered significant attention. In existing research, DD coils are the most commonly used coil structure due to their high misalignment tolerance. This study proposes a vertical DD coil structure, which significantly re...Show More
DD coil coupler is widely used in wireless power transfer system, which can improve the magnetic field in the middle of coupler. However, the edge leakage of the DD coil is always happened. This paper investigates the design of DD coils which are based on the antielectromagnetic leakage effect and analyzes the traditional DD coil model. Two solution methods are proposed for the electromagnetic lea...Show More
At present, the method of extracting highlights snippets of video is restricted to image and audio analysis in sports videos. About this problem, this paper proposes a new method of using bullet curtain text as sentiment carrier for sentiment analysis, and then using its time coupling to identify the highlight snippets. Firstly, according to the particularity of bullet curtain text, a domain senti...Show More
