A new upper bound of the basis number of the lexicographic product of graphs
( Charles Babbage Research Centre , 2010 , Article)An upper bound of the basis number of the lexicographic product of two graphs from the basis number of the factors is presented. Furthermore, the basis numbers of the lexicographic product of some classes of graphs is determined. -
Sport at Home, Sport in the World: Evaluating Qatar’s Sports Strategy from Above and Below
( Springer , 2021 , Book chapter)This piece is an overview of actors and policies concerning sport in the nation of Qatar. In recent years, sports have been given high priority in government attempts to raise exposure of the nation internationally. Many ... -
Optical solitons and qualitative analysis of nonlinear Schrodinger equation in the presence of self steepening and self frequency shift
( Elsevier , 2022 , Article)In this manuscript, the optical solitons of nonlinear Schrödinger equation (NLSE) with cubic–quintic law nonlinearity, in the presence of self-frequency shift and self-steepening, has been studied. The ultrahigh capacity ... -
Some α − ϕ-Fuzzy Cone Contraction Results with Integral Type Application
( Hindawi Limited , 2021 , Article)In this paper, we define α-admissible and α-ϕ-fuzzy cone contraction in fuzzy cone metric space to prove some fixed point theorems. Some related sequences with contraction mappings have been discussed. Ultimately, our ... -
On the sandpile model of modified wheels II
( De Gruyter Open Ltd , 2020 , Article): We investigate the abelian sandpile group on modified wheels Wˆn by using a variant of the dollar game as described in [N. L. Biggs, Chip-Firing and the critical group of a graph, J. Algebr. Comb. 9 (1999), 25–45]. The ... -
The cycle-complete graph Ramsey number r ( C 8 , K 8 )
( Tokyo University of Science , 2007 , Article)The cycle-complete graph Ramsey number r ( C m , K n ) is the smallest integer N such that every graph G of order N contains a cycle C m on m vertices or has independent number α ( G ) ≥ n . ... -
The basis number of the strong product of paths and cycles with bipartite graphs
( Central Missouri State University , 2007 , Article)The basis number of a graph G is defined to be the least integer d such that there is a basis B of the cycle space of G such that each edge of G is contained in at most d members of B. MacLane [13] proved that a graph G ... -
The theta-complete graph Ramsey number r(θk, K5); k = 7, 8, 9
( Forum-Editrice Universitaria Udinese SRL , 2021 , Article)Finding the Ramsey number is an important problem of the well-known family of the combinatorial problems in Ramsey theory. In this work, we investigate the Ramsey number r(θs, K5) for s = 7, 8, 9 where θs is the set of ... -
Large sample and bootstrap intervals for the gamma scale parameter based on grouped data
( Wayne State University , 2006 , Article)Interval estimation of the scale parameter of the gamma distribution using grouped data is considered in this article. Exact intervals do not exist and approximate intervals are needed Recently, Chen and Mi (2001) proposed ... -
Improved Likelihood Inference Procedures for the Logistic Distribution
( MDPI , 2022 , Article)We consider third-order likelihood inferences for the parameters, quantiles and reliability function of the logistic distribution. This theory involves the conditioning and marginalization of the likelihood function. The ... -
