Getting urban pedestrian flow from simple observation: realistic mobility generation in wireless network simulation
In order for precise evaluation of MANET applications, more realistic mobility models are needed in wireless network simulations. In this paper, we focus on the behavior of pedest...

On Acoustic Cloaking Devices by Transformation Media and Their Simulation
By transformation optics, we construct and investigate three-dimensional acoustic cloaking devices for which the device itself and the cloaked region can be mapped into two nested ...

How To Deal with Point Correspondences and Tangential Velocities in the Level Set Framework
In this paper, we overcome a major drawback of the level set framework: the lack of point correspondences. We maintain explicit backward correspondences from the evolving interfac...
