The best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. Among these measures, weight growth is the simplest and the most effective way to determine child growth status. Weight trend at a given(More)
The Tau Method, by construction, produces approximate polynomial solutions of differential equations. The purpose of this paper is to extend the Tau Method to the Integro-Differential equations. An efficient error estimation for the Tau method is also introduced. Details of this method are presented and some numerical results along with estimated errors are(More)
Equations of state are useful for description of fluid properties such as pressure-volume-temperature (PVT). However, the success estimation of such correlations depends mainly on the range of data which have originated. Therefore new models are highly required. In this work a new method is proposed based on Artificial Neural Network (ANN) for estimation of(More)
