Laminar burning velocities were measured by the heat flux method for premixed methane dimethyl-ether mixtures (CH4/DME) with air, at various mixture fractions from 100% CH4 to 100% DME with hydrogen addition of 0%, 20% and 40%. Experiments were carried out at atmospheric pressure and room temperature within an equivalence ratio range between 0.6 and 1.7. Four chemical kinetic mechanisms specifically...
This article proposes an audio-visual objective quality model, which is adaptive to the content changes. The major disadvantage of most existing models is that there is no unified model to evaluate the quality according to the content. So we firstly extracted the audio and video features and the correlation of the audio and video. Then we used BP neutral network to build the model, and used the subjective...
