โฆ Synopsis
A syntactical characterization will be proved, with respect to a suitable language for topology, of those sentences whose truth in one base of a topological space implies their truth in all bases of the space. Or, restating this, those sentences whose truth for a space can be 'equivalently tested in any base for the space. (An example is the HAUSDORFF axiom -that every two points are separated by open sets is equivalent to every two points being separated by basic sets.

This paper offers a novel fuzzy filter structure for edge-preserving smoothing of an image corrupted by impulsive and white Gaussian noise. This filter structure is expressed as an adaptive weighted mean filter that uses fuzzy control. The coefficients of the proposed filter can be varied adaptively
