Capturing Sensor-Generated Time Series with Quality Guarantees
We are interested in capturing time series generated by small wireless electronic sensors. Battery-operated sensors must avoid heavy use of their wireless radio which is a key cau...

Undecidability of Universality for Timed Automata with Minimal Resources
Timed automata were introduced by Alur and Dill in the early 1990s and have since become the most prominent modelling formalism for real-time systems. A fundamental limit to the al...

A Framework for Using Benefit Functions In Complex Real Time Systems
Researchers are currently investigating applying benefit, or utility functions for allocating resources in limited, soft real time systems [1,2,3]. While the future of real -time ...

On-the-Fly Controller Synthesis for Discrete and Dense-Time Systems
We present novel techniques for efficient controller synthesis for untimed and timed systems with respect to invariance and reachability properties. In the untimed case, we give al...
