Deciding Termination of Query Evaluation in Transitive-Closure Logics for Constraint Databases
We study extensions of first-order logic over the reals with different types of transitive-closure operators as query languages for constraint databases that can be described by...

Polymorphic regular tree types and patterns
We propose a type system based on regular tree grammars, where algebraic datatypes are interpreted in a structural way. Thus, the same constructors can be reused for different typ...

New geometric inference techniques for type-2 fuzzy sets
This paper presents new techniques for performing logical operations on type-2 fuzzy sets. These techniques make significant use of geometric methods to give, for the first time, ...
