The Center and Periphery of Composite Graphs

The center (periphery) of a graph is the set of vertices with minimum (maximum) eccentricity. In this paper, the structure of centers and peripheries of some classes of composite graphs are determined. The relations between eccentricity, radius and diameter of such composite graphs are also investigated. As an application we determine the center and periphery of some chemical graphs such as nan...

The vomiting center; its destruction by radon implantation in dog medulla oblongata.

I N PREVIOUS publications (I, 2) we have demonstrated with two different technics, that is, by electrical stimulation and with ablation by electrocautery, that the vomiting center is located in the dorsolateral portion of the reticular formation of the medulla oblongata. This finding is not in agreement with the contention of Hatcher and Weiss (3) that the dorsal sensory nucleus of the vagus co...

Center of Mass and its Applications in Ranking

In this paper, a novel method for ranking of fuzzy numbers are proposed. In this method, decision maker is defined based on the center of mass at some cuts of a pair of fuzzy numbers in discreet version and center of mass on all of cuts of a pair of fuzzy numbers in continuous version. Our method can rank more than two fuzzy numbers simultaneously. Also, some properties of methods are described...
