In this paper, a resolution method for propositional temporal logic is presented. Temporal formulae, incorporating both past-time and future-time temporal operators, are converted to Separated Normal Form (SNF), then both non-temporal and temporal resolution rules are applied. The resolution method is based on classical resolution, but incorporates a temporal resolution rule that can be impleme...

It is proposed a novel method to solve looped pipeline network problems that seeks to deal with limitations of the available methods The problem is modeled as a nonlinear system of equations formed by equations that cannot be solved sequentially, characterizing the resolution as a simultaneous-modular procedure. The equations of the system are the differences between the final pressure of the p...

In the present paper, the resolution method for a linguistic propositional logic with truth value in a logical algebra refined hedge algebra, is focused. The preliminaries of refined hedge algebra are given first. Then the syntax and semantic of linguistic propositional are defined. Finally, a resolution method which based on resolution principle in two-valued logic is established. Accordingly,...

High-performance digital circuits are facing increasingly severe noise problems due to cross-coupled noise injection. Traditionally, noise analysis tools use the conservative assumption that all neighbors of a net can switch simultaneously, thereby producing the worst-case noise on a net. However, due to the logic correlations in the circuit, this worst-case noise may not be realizable, resulti...

This paper presents a new, non-iterative method for super-resolution which we call the direct method. By exploiting the inherent structure of the discrete signal processing environment, the super-resolution problem can be reduced to solving a linear set of equations which relate known frequency samples to unknown time or space domain samples. The direct method is based on this concept and also ...

In this work, we aim to define a resolution method for the modal logic S5. We first propose a conjunctive normal form (S5-CNF) which is mainly based on using labels referring to semantic worlds. In a sense, S5-CNF can be seen as a generalization of the conjunctive normal form in propositional logic by including the modal connective of necessity and labels in the clause structure. We show that e...

This paper introduces an eigenvector pruning algorithm for the estimation of the signal-plus-interference eigenspace, required as a preliminary step to subspace beamforming. The proposed method considers large-aperture passive array configurations operating in environments with multiple maneuvering targets in background noise, in which the available data for estimation of sample covariances and...
