Time-frequency analysis in power measurement using complex wavelets
The problem of a useful electrical power quantification in environments with power quality problems is discussed. As it is difficult to correctly apply a Fourier-based approach, a...

Alternative axiomatics and complexity of deliberative STIT theories
We propose two alternatives to Xu’s axiomatization of Chellas’s STIT. The first one simplifies its presentation, and also provides an alternative axiomatization of the delib...

On the Relative Complexity of Resolution Refinements and Cutting Planes Proof Systems
An exponential lower bound for the size of tree-like cutting planes refutations of a certain family of conjunctive normal form (CNF) formulas with polynomial size resolution refuta...

On the Complexity of Hmelevskii's Theorem and Satisfiability of Three Unknown Equations
Abstract. We analyze Hmelevskii's theorem, which states that the general solutions of constant-free equations on three unknowns are expressible by a finite collection of formu...
