Numerical Taxonomy of Erwinia Species Using API Systems

NUMERICAL TAXONOMY AND SEED PROTEIN ANALYSIS OF HYOSCYAMUS SPECIES IN IRAN

Numerical taxonomy and seed storage protein analysis of Hyoscyamus species of Iran was carried out with the aim to illustrate species inter-relationship and to check the sub-generic taxonomic treatment proposed for the genus. Cluster analysis of morphological and protein data grouped the species in three separate clusters which supports the relationships of H. niger with H. reticulatus and H. k...

Numerical solution of linear control systems using interpolation scaling functions

The current paper proposes a technique for the numerical solution of linear control systems.The method is based on Galerkin method, which uses the interpolating scaling functions. For a highly accurate connection between functions and their derivatives, an operational matrix for the derivatives is established to reduce the problem to a set of algebraic equations. Several test problems are given...

Numerical taxonomy of the genus Glycyrrhiza in the Hyrcanian region

Noticeable variation was observed in a number of morphological characters in the Glycyrrhiza specimens in various habitats in north of Iran. To study these variations, two taxa related to the Hyrcanian region from all four known taxa of this genus in Iran, including Glycyrrhiza echinata, and G. glabra var. glabra were studied by numerical taxonomy using morphological characters in three provinc...

Thirty Years of Numerical Taxonomy

-In this history of numerical taxonomy since the publication in 1963of Sokal and Sneath's Principles of Numerical Taxonomy, I include reminiscences of the reactions of biologists in Britain and elsewhere. Much of the original program has proved sound. The debate on phenetic and phylogenetic classifications has been valuable, although the logical and theoretical aspects of phenetics have been gr...
