DOA估计：二维方向（方位、俯仰角度）扫描、方阵对某点源的导向矢量、方阵阵列信号(DOA estimation: a two-dimensional direction (azimuth and elevation angle) scan, square steering vector of a point source, the square array signal)

Reliable authorization and authentication are becoming necessary for many everyday applications such as boarding an aircraft, performing financial transaction, logging to a secure system etc. Identity verification becomes a challenging task when it has to be automated with high accuracy and with low probability of break-ins and low rates of false match. Moreover, person verification is not a new problem and society had created three traditional modes of designation: 1. Possessions: Physical possessions such as keys, passports and smart cards. 2. Knowledge: Pieces of information those are secret and known only to the right person such as PIN, passwords, user names etc. 3. Biometrics: Physiological and behavioral characteristics of individuals that distinguish one person from the others. These characteristics are different in each person.

研究松弛因子对SOR法收敛速度的影响，可为作数值分析实验的提供参考。(Study the effect of relaxation factor on the SOR method is convergent speed，it Can provide reference for numerical analysis experiment )

image registration Voxel similarity based registration algorithms generally consist in the calculation of the geometrical transformation which, when applied to the source image, maximizes a similarity function. This similarity function estimates how similar the images are once the transformation has been applied. (image registration)
