A growing number of comparative analyses in the field of parasite evolution and ecology have used phylogenetically based comparative methods. However, the comparative approach has not been used much by parasitologists. We present the rationale for the use of phylogenetic information in comparative studies, and we illustrate the use of several phylogenetically based comparative methods with case...

in this paper, we conduct a comparative study between the homotopy perturbation method (hpm) and adomian’s decomposition method (adm) for analytic treatment of nonlinear volterra integral equations, and we show that the hpm with a specific convex homotopy is equivalent to the adm for these type of equations.

The work  addressed in this paper is a comparative study between convergence of the  acceleration techniques, diagonal pad'{e} approximants and shanks transforms, on Homotopy analysis method  and Adomian decomposition method for solving  differential equations of integer and fractional orders.

every year, with regard to rapid development of data, grid computing that is a kind of distributed computing system is that it has attracted the attention of most people and considerably taken into account. computing that cannot be done by huge computers can be performed by grid computing. if load balance is used, efficiency will increase in grid. resources have an important and effective role ...

the aim of this study was to use ahp method to rank the obstacles to improving professional ethics in sport media. in the first step, the existing obstacles were identified by review of literature, searching the authentic websites and finally interview with sport media experts. after this step, the hierarchy tree was portrayed to rank the obstacles and then the analytical hierarchy process (ahp...

One way is to look at Darwin’s definitions of the term “species” and to use a comparative method analogous to the comparative method in biology, comparing and contrasting Dar‐ win’s definitions with those of his contemporaries, with his predecessors, and with defini‐ tions today. This is the method favoured typically by philosophers of biology and biologists who are concerned with history, and ...
