Decentralized Reasoning about Gradual Changes of Topological Relationships between Continuously Evolving Regions
A key challenge facing many applications of new geosensor networks technology is to derive meaningful spatial knowledge from lowlevel sensed data. This paper presents a formal model for representing and computing topological relationship changes between continuously evolving regions monitored by a geosensor network. The definition of “continuity” is used to constrain region evolution and enable...
متن کاملمدلسازی روابط توپولوژیک سه بعدی فازی در محیط GIS
Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...
متن کاملThe Structural Relationship Between Topological Indices and Some Thermodynamic Properties
The fact that the properties of a molecule are tightly connected to its structural characteristics is one of the fundamental concepts in chemistry. In this connection, graph theory has been successfully applied in developing some relationships between topological indices and some thermodynamic properties. So , a novel method for computing the new descriptors to construct a quantitative rela...
متن کاملDeriving Topological Relationships Between Simple Regions with Holes
Topological relationships between objects in space are of great importance in many disciplines. Due to the lack of local topological information between components, i.e. faces, in the model of topological relationships between complex regions, recently, localized topological relationships have been defined for complex regions based on the relationships between simple regions with holes. However...
متن کاملDecentralized querying of topological relations between regions monitored by a coordinate-free geosensor network
Geosensor networks present unique resource constraints to spatial computation, including limited battery power, communication constraints, and frequently a lack of coordinate positioning systems. As a result, there is a need for new algorithms that can efficiently satisfy basic spatial queries within those resource constraints. This paper explores the design and evaluation of a family of new al...
