We compare the potential of two classes of linear and hierarchical models of discourse to determine co-reference links and resolve anaphors. The comparison uses a corpus of thirty texts, which were manually annotated for co-reference and discourse structure.

In this paper, we propose an algorithm for the construction of substitution-box (S-box) through a linear recurrence relation. S-box is considered as building block ciphers; here, present technique to construct S-boxes by using relation comply with standards cryptographically secure S-box. We have witnessed that latest research relies more on improving already existing techniques, rather than de...
