The solutions for free axisymmetric vibration equations of thin shell in low frequency range found in perturbation method consist of four analytic bending solutions which are only edge effects and two membrane solutions which are usually obtained by numerical calculation.

This paper extends the theory of 3-station 2D TDOA location,in order to apply it in space 4-station TDOA location system to deal with its possible ambiguity and non-solution phenomena.

The ambiguity and non-solution problem of TDOA and DOA location system on missile is studied in this paper.

Packet scheduling based on matrix decomposition in optical switches;

Direction finding in the presence of coherent signals based on data matrix decomposition;

In order to solve the problem of inverse kinematics for general 6R robots,an algorithm with high accuracy based on symbolic preprocessing and matrix decomposition was proposed.

The basic solution matrix of linear homogeneous system with constant coefficients is found completely through using Jordan canonical form.

Dealing with such a general situation, this paper solves homogeneous linear differential equation E = AE and the structure problem of the basic solution matrix with a very elementary method.

We obtain basic solution matrix of special equations by means of analogy and obtain boundary theorem of solution for unsolvable equations by means of integral inequality and Liapunov function.
