Checking Emptiness of Non-Deterministic Regular Types with Set Operators
An algorithm to decide the emptiness of a regular type expression with set operators given a set of parameterized type definitions is presented. The algorithm generalizes previous...

On the Accuracy of Type-2 Fuzzy Sets
— Geometric Type-2 Fuzzy sets allow us to model type-2 fuzzy sets using geometry providing significant improvement in speed of computation. This paper explores in detail how wel...

A Fast Geometric Method for Defuzzification of Type-2 Fuzzy Sets
Generalised type-2 fuzzy logic systems can not currently be used for practical problems because the amount of computation required to defuzzify a generalised type-2 fuzzy set is to...

New negative Latin square type partial difference sets in nonelementary abelian 2-groups and 3-groups
A partial difference set having parameters (n2, r(n - 1), n + r2 - 3r, r2 - r) is called a Latin square type partial difference set, while a partial difference set having paramete...
