− Nowadays, there are lots of classic and alternative method that has been used to obtain and compute transfer function for a linear network. Although, problems still occur especially in the number of nodes, loops and simultaneous equations that need to be solved by this approaches. A proposed approach called NIRE (Network-Impedance Relationship Equation) will solve these problems by developing...

A set S ⊆ V is a dominating set of a graph G = (V, E) if each vertex in V is either in S or is adjacent to a vertex in S. A vertex is said to dominate itself and all its neighbors. The domination number γ (G) is the minimum cardinality of a dominating set of G. A set S ⊆ V is a total dominating set of a graph G = (V,E) if each vertex in V is adjacent to a vertex in S. The total domination numbe...

seismic waves travelling through inelastic media are attenuated by the conversion of elastic energy into heat. upon being attenuated, the travelling wave changes: amplitude is reduced, travelling waveform is modified due to high-frequency content absorption, and phase is delayed. attenuation is usually quantified through the quality factor q: the ratio between the energy stored and lost in each...

in this paper, the variational iteration method proposed by ji-huan he is applied to solve both linear and nonlinear schrodinger equations. the main property of the method is in its flexibility and ability to solve linear and nonlinear equations accurately and conveniently. in this method, general lagrange multipliers are introduced to construct correction functionals to the problems. the multi...

An analysis is carried out for axisymmetric stagnation flow of a micropolar nanofluid in a moving cylinder with finite radius. The coupled nonlinear partial differential equations of the problem are simplified with the help of similarity transformations and the resulting coupled nonlinear differential equations are solved analytically by homotopy analysis method HAM . The features of the flow p...

abstract. the main contribution of the current paper is to propose a new effective numerical method for solving the first-order linear matrix differential equations. properties of the legendre basis operational matrix of integration together with a collocation method are applied to reduce the problem to a coupled linear matrix equations. afterwards, an iterative algorithm is examined for solvin...
