Typically, program design involves constructing a program P that implements a given specification S; that is, the set P of executions of P is a subset of the set S of executions s...
We consider spatial databases and queries definable using first-order logic and real polynomial inequalities. We are interested in topological queries: queries whose result only ...
Concurrent error detection (CED) techniques (based on hardware duplication, parity codes, etc.) are widely used to enhance system dependability. All CED techniques introduce some ...
We develop a model for timed, reactive computation by extending the asynchronous, untimed concurrent constraint programming model in a simple and uniform way. In the spirit of pro...
FLUX belongs to the high-level programming languages for cognitive agents that have been developed in recent years. Based on the established, general action representation formali...
