The work is concerned with investigation of spatio-temporal phenomena on mutually coupled CNN array. Besides pattern formation and active wave propagation, we found that other interesting spatio-temporal phenomena such as phaseinversion-wave and classical waves can be also observed in the same network structure. In particular, we focus our discussion on the relations of spatio-temporal phenomen...

Object-Relational Database (ORDB) techniques are developed rapidly in recent years and widely used for spatial data storage and manipulation. The ORDB has strong basis both on theories and applications, and if well extended, it can also be used to handle spatio-temporal data. Although ample research on spatio-temporal data modeling has been performed, very little work exists on how to implement...

riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. in this research, spatio-temporal change of vegetation riparian area of aghbolagh-river as an upstream of karoon-river for 65-...

The notion of spatio-temporal multi-granularity is fundamental when modeling objects in GIS applications in that it supports the representation of the temporal evolutions of these objects. Concepts and issues in multi-granular spatio-temporal representations have been widely investigated by the research community. However, despite the large number of theoretical investigations, no comprehensive...

As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is important to associate the spatio-temporal process with a vivid representation. The paper propose a way for visualization base on dynamic symbol base, by which represent the spatio-temporal process in a more vivid and visual...
