In this paper we propose a Petri net based representation for planning problems. The motivation for this is that Petri nets are a formal tool useful to model and analyse domains involving true parallelism, concurrency, conflicts, and causal relations which are beyond the scope of classical planning. In (Silva, Castilho, & Künzle 2000) we presented a way to(More)

In this paper, we describe how magnetoresistive sensors can be integrated with microelectromechanical systems (MEMS) devices enabling the mechanical modulation of DC or low frequency external magnetic fields to high frequencies using MEMS structures incorporating magnetic flux guides. In such a hybrid architecture, lower detectivities are expected when(More)
