Abstract
Positron annihilation technology is used to study the behavior of flow and an algorithm is proposed to track tracer particle without a priori knowledge of the initial location of the particles. The features points is extracted from the original slice image group, the trajectory is linked by using Kuhn-Munkres algorithm and smoothed by using Kalman filter algorithm, and the 3D motion trajectory image and the average velocity value can be obtained finally. A series of experiments is performed to test the effectiveness of the approach. Experimental results show that positron annihilation technology is capable as a means of examining characteristics of flow regime.

Creeping flow of micropolar fluid past a porous sphere
The creeping flow of incompressible micropolar fluid past a porous sphere with permeability k is studied assuming uniform flow far away from the body. The stream function is determined by matching the solutions of Stokes equations for the flow outside ...
