An Efficient Index Lattice for XML Query Evaluation
Abstract. We have defined an XML structural index called the Structure Index Tree (SIT), which eliminates duplicate structures arising from the equivalent subtrees in an XML docume...

Note on pseudolattices, lattices and submodular linear programs
A pseudolattice L is a poset with lattice-type binary operations. Assuming that the pseudolattice permits a modular representation as a family of subsets of a set U with certain c...

On achievable security levels for lattice data hiding in the known message attack scenario
This paper presents a theoretical security analysis of lattice data hiding. The security depends on the secrecy of a dither signal that randomizes the codebook. If the same secret...

Algebraic and proof-theoretic characterizations of truth stressers for MTL and its extensions
Extensions of monoidal t-norm logic MTL and related fuzzy logics with truth stresser modalities such as globalization and “very true” are presented here both algebraically in ...

About the Universality of the Billiard ball model
Block cellular automata (BCA) make local, parallel, synchronous and uniform updates of in nite lattices. In the one-dimensionalcase, there exist BCA with 11 states which are unive...
