Situational decomposition in controlling complex objects

Controlled Decomposition Strategy for Complex Spatial Objects

The efficient query processing for complex spatial objects is one of most challenging requirements in many non-traditional applications such as geographic information systems, computer-aided design and multimedia databases. The performance of spatial query processing can be improved by decomposing a complex object into a small number of simple components. This paper investigates a natural trade...

Evolution in complex objects

This paper describes work carried out on a model for the evolution of graph classes in complex objects. By defining evolution rules and propagation strategies on graph classes, we aim to define a user-definable means to manage data evolution model which tackles the complex nature of the classes managed, using the concepts defined in object systems. So, depending on their needs and on those of t...

Controlling Synchronization in Complex Networks

Examples of synchronization can be found in a wide range of phenomena. While in several situations the formation of a coherent state is positive as, for example, in the blinking of fireflies to attract partners and the synchronized motion of bearings, in many others it is unpleasant and should be mitigated. Examples are the epileptic seizures, traffic congestion in communication networks, and t...
