In order to evaluate complex system in selection of aircraft scheme, the evaluation method based on cloud model was utilized. This paper analyzed the evaluation steps based cloud model. Because of imprecision in judgment from cloud model figure in past, the measurement method of cloud comparability was introduced to judge which rating the evaluation result belongs to. Finally, the application in the...
The internal ring matrix distribution of many special ceramic porous medium tubes on a circular plate constitutes an adsorbent device, which can retain nanoparticles aerosol agglomerate by the way of collision, adsorption and diffusion in the process of mass transfer. In this paper, the behavior of industrial flue dust diffusion in the ceramic porous medium device is researched by computational fluid...
In order to avoid the blocky effects of second-order PDE model and preserve edges, a new fourth-order PDE model was proposed in this paper. Based on four-neighbor system, a simple and symmetrical difference scheme was also developed to make the model more efficient and reliable. Median filtering was utilized to alleviate the speckle effects in the processed image at last. We remove the Gaussian noises...
