In this paper, we develop a theory of modular design and refinement of hierarchical hybrid systems. In particular, we present compositional trace-based semantics for the language ...
Visual description techniques are particularly important for the design of hybrid systems because specifications of such systems must usually be discussed between engineers from a ...
We introduce a mathematical model of components that can be used for the description of both hardware and software units forming distributed interactive systems. As part of a distr...
We identify a new class of decidable hybrid automata: namely, parallel compositions of semi-algebraic o-minimal automata. The class we consider is fundamental to hierarchical model...

We propose a hybrid, unsupervised document clustering approach that combines a hierarchical clustering algorithm with Expectation Maximization. We developed several heuristics to ...
