Continuous Constraint Query Evaluation for Spatiotemporal Streams
In this paper we study the evaluation of continuous constraint queries (CCQs) for spatiotemporal streams. A CCQ triggers an alert whenever a configuration of constraints between s...

Path Feasibility Analysis for String-Manipulating Programs
We discuss the problem of path feasibility for programs manipulating strings using a collection of standard string library functions. We prove results on the complexity of this pro...
