 variable transformation
 This problem comes from the variable transformation for fitting a regression model. By using the Hirota's bilinear method, the homoclinic orbits of the Davey-Stewartson Equations were obtained through the dependent variable transformation. An exact differential relation between the void radius and surface load was obtained by using the variable transformation method. An appropriate generalization ofCharnes-Cooper's [1962] variable transformation is introduced, by which a parameter-free convex program is associated to nonlinear fractional programs. The algorithm is based on the CIP (cubic-interpolated propagation) method combined with variable transformation. 更多
 transformation of variables
 We introduce a transformation of variables that gives a number of important advantages in the numerical solution of the problem under consideration. A transformation of variables that reduces the system of boundary-layer equations to a form suitable for analysis and solution is derived. We exhibit a transformation of variables which allows the simultaneous factorization of a multiparticle Veneziano term and its twisted counterpart (obtained by reversing the order of the intial or final particles). For this reason, the procedure is modified by using a suitable transformation of variables which reduces the determination of the transmitted wave to the solution of the K.d.V. A multiple scale transformation of variables is used, here, to get rid of these secular terms. 更多
