1.1 The number.dat data file from Shepard, Kilpatric, and Cunningham (1975). 11 3.1 A proximity matrix, morse digits.dat, for the 10 Morse code symbols representing the first ten digits 9.1 Order-constrained least-squares approximations to the digit proximity data of Shepard et al. (1975); the upper-triangular portion is anti-Robinson and the lower-triangular portion is strongly-anti-9.2 The 45...
In this paper simple formulae are derived for calculating the number of spanning trees of different product graphs. The products considered in here consists of Cartesian, strong Cartesian, direct, Lexicographic and double graph. For this purpose, the Laplacian matrices of these product graphs are used. Form some of these products simple formulae are derived and whenever direct formulation was n...
Consider G(E,V) be a finite, undirected and simple connected graph. This paper includes study of some properties that illustrate the relations between three numbers in a graph which are chromatic, domination, and independence with special restrictions. Finally, we compute these parameters in a new graph namely K4 -isosceles triangular graph.
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
This paper proves that for any integer n ≥ 4 and any rational number r, 2 ≤ r ≤ n − 2, there exists a graph G which has circular chromatic number r and which does not contain Kn as a minor.
The concept of a defective circular coloring is introduced, and results shown for planar, series-parallel, and outerplanar graphs. Numerous problems are also stated.
Triangular latt ice Electromagnetic Band-Gap (EBG) St ructure in the ground plane is used in the design of a Triangular Microstrip Patch Antenna (TMPA) Array to improve its bandwidth. The patch elements are equilateral t riangular in shape. The Equilateral Triangular Microstrip Patch Antenna (ETMPA) Array design has four patch elements in 2×2 form with ground plane having circular cutouts formi...
This study investigated the effects of screwdriver handle shape, surface, and workpiece orientation on subjective discomfort, number of screw-tightening rotations, screw-insertion time, axial screwdriving force, and finger contact forces in a screwdriving task. Handles with three longitudinal cross-sectional shapes (circular, hexagonal, triangular), four lateral shapes (cylindrical, double frus...
