The mechanism underlying perceptual grouping of visual stimuli is not static, but dynamic. In this paper, the dynamical grouping process is implemented with a neural network model consisting of an array of (hyper)columns suggested by Hubel ̄ "vViesel, where intracolumnax inhibition and intercolumnax facilitation axe incorporated ̄ The model was applied successfully to figures consisting of a set ...

In this paper, we propose a cost effective IP paging protocol, which can be used for terminal paging in next-generation wireless IP networks. In the existing IP paging protocols, a paging request packet is delivered to access routers belonging to a paging area by unicast or multicast. However, unicast and multicast result in higher cost, so that we present a selective paging algorithm utilizing...
