Supporting Aggregate Queries Over Ad-Hoc Wireless Sensor Networks
We show how the database community’s notion of a generic query interface for data aggregation can be applied to ad-hoc networks of sensor devices. As has been noted in the senso...

Modelling Spatial Relations by Generalized Proximity Matrices
One of the main challenges for the development of spatial information theory is the formalization of the concepts of space and spatial relations. Currently, most spatial data struc...

A general strategy for decomposing topological invariants of spatial databases and an application
Topological invariants of spatial databases (i.e., finite structures that capture the topological properties of the database) are receiving increasing attention since they can act...

Representation of Two Bipolar Decision Strategies with Generalized Choquet Integrals
We study the notion of conditional relative importance in a quantitative framework. This is an important notion in the context of the Choquet integral since this latter is usually...

A Decidable Class of Groundable Formulas in the General Theory of Stable Models
We present a decidable class of first-order formulas in the general theory of stable models that can be instantiated even in the presence of function constants. The notion of an ...
