ALEJANDRO B. ENGEL, SILVIO JOSE BEZERRA, SIGUEMITUSO ARIE

The classical models for volumelry of the heart's left ventricle are based upon the simplifying assumption that this chamber is an ellipsoid. This simplification is needed in…

PROOF OF A FUZZY REGULAR LANGUAGE THEOREM BY USING LEVEL SETS—A NOTE

EDWARD T. LEE

Fuzzy languages and level sets are defined and illustrated by examples. Properties of level sets are presented. A fuzzy regular language theorem may be proved through the use of…
