In this paper we classify digital covering spaces using the conjugacy class corresponding to a digital covering space.
In (Chaudhuri and Rosenfeld, 1996), metrics were developed for fuzzy sets u and v defined on the same support set S. These metrics are based on applying the Hausdorff metric to pairs of membership level sets (u-1 ([ tk, 1 ]), v-1 ([ tk, 1 ])), where tk E [0, 1] is a (possible) membership value of u or v. The metrics of (Chaudhuri and Rosenfeld, 1996) give… (More)
In this paper we study digital versions of some properties of covering spaces from algebraic topology. We correct and improve upon the presentation of assertions in Han's papers [10,11].
Hydrogen peroxide levels were measured in the breath condensate of 43 patients receiving mechanical ventilation. In 16 patients the mean breath condensate peroxide level was 1.68 +/- 0.35 mumol/l on the day they met diagnostic criteria for adult respiratory distress syndrome (ARDS). The peak breath condensate peroxide level in the 27 patients in whom ARDS… (More)
