Time Series Prediction by Perturbed Fuzzy Model
This paper presents a fuzzy system approach to the prediction of nonlinear time series and dynamical systems based on a fuzzy model that includes its derivative information. The u...

The Logic of Perfect MV-algebras
In this paper we summarize results on perfect MV-algebras and we show that the class of first order Lukasiewicz formulas valid in all interpretations over perfect MV-chains is ax...

Algorithms for the Construction of Digital Convex Fuzzy Hulls
We consider a digital fuzzy set placed in Oxyplane, with support which is a set of digital points (centroids) in Z2 . We consider two kinds of convexity of a fuzzy set, namely qua...
