purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

We give bijective proofs that, when combined with one of the combinatorial proofs of the general ballot formula, constitute a combinatorial argument yielding the number of lattice paths from (0, 0) to (n, rn) that touch or cross the diagonal y = rx at exactly k lattice points. This enumeration partitions all lattice paths from (0, 0) to (n, rn). While the resulting formula can be derived using ...

Hindi is an Indian language which is relatively rich in morphology. A few morphological analyzers of this language have been developed. However, they give only inflectional analysis of the language. In this paper, we present our Hindi derivational morphological analyzer. Our algorithm upgrades an existing inflectional analyzer to a derivational analyzer and primarily achieves two goals. First, ...
