On Closure Operator for Interval Order Structures
A closure operator for interval order structures has been introduced and its basic properties analysed. The operator is an equivalence of 3-closure operator of [11] for stratified ...

Encoding Closure Operators into Neural Networks
Motivated by basic ideas from formal concept analysis, we propose two ways to directly encode closure operators on finite sets in a 3-layered feed forward neural network.

Closure Operators for Order Structures
We argue that closure operators are fundamental tools for the study of relationships between order structures and their sequence representations. We also propose and analyse a clos...

Pseudocomplements of closure operators on posets
Some recent results provide su cient conditions for complete lattices of closure operators on complete lattices, ordered pointwise, to be pseudocomplemented. This paper gives resu...

Managing RBAC states with transitive relations
In this paper, we study the maintenance of role-based access control (RBAC) models in database environments using transitive closure relations. In particular, the algorithms that ...
