Strains are applied to the integration procedure in nonlinear increments todecrease the errors arising from the linearization of plastic equations. Two deformationvectors are used to achieve this. The first vector is based on the deformations obtained bythe first iteration of the equilibrium step, and the second is acquired from the sum of thesucceeding iterations. By applying these vectors and...

Rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (SCAL). The challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (SCAL defined) in the re...

this article uses seasonal integration and co integration techniques to test the hypothesis of neutrality of money, using data from the iranian economy. seasonal data for the three variables of money supply, output and prices show that (increase in) money supply and the price level are co integrated at zero frequency, but one does not see such a relationship between (increase in) money supply a...
