A Con uent Connection

چکیده
This work 1 is concerned with basic issues of the design of cal-culi and proof procedures for rst-order connection methods and tableaux calculi. Proof procedures for these type of calculi developed so far suuer from not exploiting proof connuence, and very often unnecessarily rely on a heavily backtrack oriented control regime. As a new result, we present a variant of a connection calculus and prove its strong completeness. This enables the design of backtrack-free control regimes. To demonstrate that the underlying fairness condition is reasonably implementable we deene an eeective search strategy.

State Space Reduction using Partial -Con uence
We present an e cient algorithm to determine the maximal class of con uent -transitions in a labelled transition system. Con uent -transitions are inert with respect to branching bisimulation. This allows to use -priorisation, which means that in a state with a con uent outgoing -transition all other transitions can be removed, maintaining branching bisimulation. In combination with the removal...

In this paper we rst show that a con uent Vandermonde matrix may be viewed as composed of some rows of a certain block Vandermonde matrix As a result we derive a Sylvester s structure for this class of matrices that ap pears as a natural generalization of the straightforward one known for usual Vandermonde matrices Then we present some applications as an illustration of the established structur...

A language L is con uent with respect to a given quasi order on if, for any x; y 2 L, there is z 2 L such that x z and y z. L is con uent with respect to in generalized sense if it is a nite union of languages conuent with respect to . We investigate in this paper the decidability of the generalized con uence problem with respect to the pre x partial order and the factor partial order for conte...
متن کاملModel for Con uent Dynamic Data - Flow Networks
We introduce a state-based language for programming dynamically changing networks which consist of processes that communicate asynchronously. For this language we introduce an operational semantics and a notion of observable which includes both partial correctness and absence of deadlock. Our main result is a compositional characterization of this notion of observable for a con uent sub-languag...
متن کاملProsodic analysis of fillers and self-repair in Japanese speech
The prosodic features of lled pauses ( llers) and selfrepair are investigated with a view towards the detection of dis uencies. First, we compare the prosodic features of typical llers and their uent homonyms using read sentences of identical phoneme sequences. It is con rmed that the llers (1) have at least 2 times longer duration than their non-dis uent counterparts, (2) tend to be followed b...
