Phase singularities for image representation and matching
Phase features are widely used in image processing and representation due to their stability to deformation and noise [1, 2]. However, phase singularities,where the signals vanish...

The Theory of Natural Movement and its Application to the Simulation of Mobile Ad Hoc Networks (MANET)
The theory of natural movement is fundamental to space syntax: a set of theories and methods developed in the late 1970s that seeks, at a general level, to reveal the mutual effec...
