We present a streaming algorithm for constructing sparse spanners and show that our algorithm out-performs signiļ¬cantly the state-of-the-art algorithm for this task [20]. Speciļ¬...
This paper presents an XML-based approach to implementing the parametric model of temporal databases. In the parametric model, attribute values are functions of time and the entir...
Abstract. We extend Angluinās algorithm for on-line learning of regular languages to the setting of timed systems. We consider systems that can be described by a class of determi...
We provide machine-independent characterizations of some complexity classes, over an arbitrary structure, in the model of computation proposed by L. Blum, M. Shub and S. Smale. We ...

We develop a framework for specifying and reasoning about policies for sharing resources in coalitions, focussing here on a particular, common type of contract in which coalition ...
