By using active set strategy, the authors need only to solve a reduced trust region subproblem which is solved inexactly by the truncated conjugate gradient method.
This homotopic method is an approximate analysis method, which can be more used for analyzing other behavior of the sea surface temperature anomaly of the atmosphere-ocean oscillator model.
Through the reduction of friction force and deformation force between the steel wire and die,the tensile failure problem of steel wire workblank during the stamping process was resolved.
To achieve such a rapid and low complexity of the distribution,and it proposes a semiregular mesh geometry coding related to the reconstruction of the mean square error of approximation.
