Research on Model Transformation and Its Application Based on Model Driven Architecture Framework;

By means of the model transformation and the replacement of ellipsoid and elliptical cylinder with sphere and circular cylinder,rapid calculation of the mathematical models is made possible.

The detail modeling of tunnel structure attached establishment is presented and how the technique of OpenGL, including modeling, lighting, material, model transformation and view point transformation, is applied on visualization of tunnel is described.

For fuzzy relation inequality system B ≤R A≤ B ,after its fuzzy relation R is obtaind using sign matrix method, fuzzy mapping R is changed into R * as the new input of fuzzy relation in the preparatory system.

The problem of fuzzy mapping algorithms with multiple indices having excessively small weighing vector components was analyzed to preclude irrational evaluation results arising in the fuzzy evaluation of product structural designs.

Aiming at the need for 3D modeling of sophisticated weapon,the development methods of software engineering such as waterfall model,transform model and increment model were analyzed and compared,and the increment model was introduced into 3D modeling for weapon.

Based on the analysis of the imaging process of optoelectronic imaging anti-ship missile, an automatic registration algorithm is proposed, and its basic idea is to decompose the transform model and simplify it step by step.

Considering the problem that all currently available phase-mode transformation matrices can not reflect all types of faults, a novel phase-mode transformation matrix is proposed in this paper.

Considering the deficiencies of the used phase-mode transformation and wavelet transform in the available transmission line fault location algorithms,an improved algorithm for the fault location based on a new phase-mode transformation matrix and lifting wavelet is proposed.
