A connected graph is one in which every vertex, or point (or, in the case of a solid, a corner), is connected to every other point by an arc; an arc denotes an unbroken succession of edges. A route that never passes over an edge more than once, although it may pass through a po...
Moreover, we determine the exact value of σ(Pn,k) for k ∈ {1, 2}. The rna numbers of some famous generalized Petersen graphs, namely, Petersen graph, Dürer graph, Mbius-Kantor graph, Dodecahedron, Desargues graph and Nauru graph are also computed. Recently, Acharya, Ku...
dodecahedron (Figure 16). AHamilton circuitis one that passes through each point exactly once but does not, in general, cover all the edges; actually, it covers only two of the three edges that intersect at eachvertex. The route shown in heavy lines is one of several possible Hamilton ...
I agreed to be one of the interviews. I explained to Tally that my method of study is based on dreams and coincidences. After discussing the subject on the telephone, we decided that I would explain a little about the number72and more about the ancient numbering Code system, found worldwid...

Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons have properties that depend sensitively on the number of constituent particles. Certain numbers are termed ‘magic’ because they grant the system with closed shells
But on the air side, the fully developed Nusselt number is between NuH and NuT (chose to NuH), the Sherwood number is a little less than the fully developed Nusselt number. The two numbers are decreasing with an increase of the packing fraction. Whereafter, Zhang et al. [44] studied ...

Given a polyhedron, the number of its unfolding is obtained by the Matrix-Tree Theorem. For example, a cube has 384 ways of unfolding (i.e., cutting edges). By omitting mutually isomorphic unfoldings, we have 11 essentially different (i.e., nonisomorphic) unfoldings. In this paper, we...
Euler’s theorem on polyhedra is used to calculate the number of vertices, edges, and faces in domes, number of atoms, bonds, and pentagonal and hexagonal rings in fullerenes, and number of proteins and protein–protein contacts in viruses. The T-number, the characteristic for the CK ...
