A general numerical model to identify multi-variables of the unidimensional non-linear inverse problem of heat conduction in transient state is presented by a precise algorithm for direct heat conduction, based on Bregman distances in the construction of regularization terms in Tikhonov’s function.

An application of a self-adaptive precise algorithm in time domain is presented in this paper for solving self-excited vibration problems.

Based on the precise integration method of the exponential matrix, we discuss the solution of the state equations for nonlinear dynamics system governed by the equation =H·v+f(v,t).

To raise the calculation precision of active structural control, the closed-loop and closed-open-loop control algorithms for instantaneous structural optimization were improved based on the active structural control strategy and the precise integration method (PIM).
