Algebraic connectivity and degree sequences of trees
(Elsevier Science Inc, 20090115)We investigate the structure of trees that have minimal algebraic connectivity among all trees with a given degree sequence. We show that such trees are caterpillars and that the vertex degrees are nondecreasing on every ... 
Amplitude modulation of nonlinear waves in a fluidfilled tapered elastic tube
(Elsevier Science Inc, 20040715)In the present work, treating the arteries as a tapered, thin walled, long and circularly conical prestressed elastic tube and using the reductive perturbation method, we have studied the amplitude modulation of nonlinear ... 
Complex travelling wave solutions to the KdV and Burgers equations
(Elsevier Science Inc, 200503)In the present work, making use of the hyperbolic tangent method, some complex travelling wave solutions to the KortewegdeVries and Burgers equations are obtained. It is observed that the real part of the Solution for the ... 
Graphs of given order and size and minimum algebraic connectivity
(Elsevier Science Inc, 20120401)The structure of connected graphs of given size and order that have minimal algebraic connectivity is investigated. It is shown that they must consist of a chain of cliques. Moreover, an upper bound for the number of maximal ... 
Harmonic mappings related to the mfold starlike functions
(Elsevier Science Inc, 20150915)In the present paper we will give some properties of the subclass of harmonic mappings which is related to mfold starlike functions in the open unit disc D = {z parallel to z vertical bar < 1}. Throughout this paper we ... 
The modified reductive perturbation method as applied to Boussinesq equation: strongly dispersive case
(Elsevier Science Inc, 20050505)In this work, we extended the application of "the modified reductive perturbation method" to Boussinesq equation for strongly dispersive case and tried to obtain the contribution of higher order terms in the perturbation ... 
Multiple time scale formalism and its application to long water waves
(Elsevier Science Inc, 201005)In the present work, by employing the multiple time scaling method, we studied the nonlinear waves in shallowwater problem and obtained a set of KortewegdeVries equations governing the various order terms in the ... 
A note on the progressive wave solution of the perturbed KortewegdeVries equation with variable dissipation
(Elsevier Science Inc, 20141201)In this note, utilizing the method presented in Engelbrecht (1991) and Demiray (2002) we have studied the propagation of progressive waves in perturbed KdV equation with variable dissipation coefficient. The cases of ... 
A note on the wave propagation in water of variable depth
(Elsevier Science Inc, 20111101)In the present work, utilizing the two dimensional equations of an incompressible inviscid fluid and the reductive perturbation method we studied the propagation of weakly nonlinear waves in water of variable depth. For ... 
On the class of harmonic mappings which is related to the class of bounded boundary rotation
(Elsevier Science Inc, 20150915)The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ... 
Subclass of mquasiconformal harmonic functions in association with Janowski starlike functions
(Elsevier Science Inc, 20180215)Let's take f(z) = h (z) + <(g(z))over bar> which is an univalent sensepreserving harmonic functions in open unit disc D = {z : vertical bar z vertical bar < 1}. If f (z) fulfills vertical bar w(z)vertical bar = ...
