Explosion airflow extinguishing arc is a new kind of lightning protection methods. Establishing mathematical chain model is to study the effect of arc extinction. Under the strong disturbance of gas stream, temperature conductivity of arc and energy variation can be deduced in considering the many parameters of the arc. Using finite difference method is to analysis the movement of arc extinction under...
In this paper, we propose a video summarization method based on the Temporally Maximum Occurrence Frame (TMOF). First, the key frames are extracted from the video and then they are clustered by calculating the distance between their feature vectors; the TMOF is constructed in the clustered collection. Finally, the video summarization is formed by the frames with the smallest distance from the TMOF...
Wear is one of the main factors of machine failure, wear failure holds more than 70% of mechanical parts failure. Debris carries a lot of information of running devices. Inductive sensor is wildly used in online detection of oil debris. But most of the former studies are based on the single-layer solenoid model of the inductive sensor. In this paper, the basic principle of the multilayer inductive...
Video key frame extraction has been an important issue for video index and retrieval. In this paper, we propose a key frame extraction method based on the temporally maximum occurrence frame (TMOF). We took the hybrid projection value of image as the feature vector of the frames, and used the distance between the vectors to fragment video shot into sub-shots. Then, we constructed TMOF and selected...
The demands for high data rates and spectrally efficient modulation techniques are increasing due to the evolution of multimedia service in wireless communication systems. Bit-interleaved coded modulation with iterative decoding (BICM-ID) is a bandwidth efficient transmission scheme, which is suitable for next-generation wireless communication systems. In order to exploit the time-varying nature of...
