Because it is hard to depict real world traces, researchers proposed some mobility models in the study of mobile ad-hoc networks. It is aware recently that some mobility models will lead to non-uniform node distribution, which decreases the credibility and validity of simulations. Many researchers reconsider the node distribution characteristic for random waypoint model and have gotten some valuable...
Motion saliency is the key component for the video saliency model, and attracts great research interest. However, there is few universal predictor of motion saliency. In this paper, a novel method for generation of motion saliency is proposed, in which motion saliency map is obtained through the multi reference frames, and enhanced by spatial saliency information. The proposal can obtain more detailed...
Duncan E-B model has been widely used in engineering practice. And how to determine the parameters of the model accurately and easily is the main step to ensure the reliability of the results. Based on BP neural network in MATLAB toolbox, this paper aim to establish the non-linear relation between the density γ, porosity e and the constitutive model parameter K (Kb, Rf, Q0) which is difficult to be...
