the normalized full gradient (nfg) method defined by berezkin (1967, 1973 and 1998) is used for downward continuation maps. analytical downward continuation is a method to estimate the field closer to the source and consequently results in a better resolution of underground rock distribution. however, the usefulness of this process is limited by the fact that the operation is extremely sensitiv...

A technique for accelerating global convergence of pseudo-transient continuation Newton methods is proposed based on residual smoothing. The motivated by the effectiveness local nonlinear smoothers at overcoming strong transients. In limit a small pseudo-time step, method reduces to smoothing technique, while in large steps, an exact recovered along with its quadratic properties. formulation re...

In this article the homotopy continuation method (HCM) to solve the forward kinematic problem of the 3-PRS parallel manipulator is used. Since there are many difficulties in solving the system of nonlinear equations in kinematics of manipulators, the numerical solutions like Newton-Raphson are inevitably used. When dealing with any numerical solution, there are two troublesome problems. One is ...
