Firstly, we detect singularities based on block images through shifting position of the whole image time after time at the same block size, get the concentrative region of singularities detected on different positions and compute the centroid of the region to gain the accurate position of singularities.
The paper proposes an algorithm for distilling fingerprint orientation in the multilevel block size, which adjusts the fingerprint orientation in the small block size resting on the fingerprint orientation in the big block size.
Firstly, the singularities are detected based on block images through shifting position of the whole image time after time at the same block size and the concentrative region of singularities detected under different positions is got and the centroid of the region is computed to gain the accurate position of singularities.
It is found that the drawing manner has the different adaptation to the top coal which has different block distribution. The caving capacity is mainly decided by the block size. The top-coal which has layer difference of block with the same size has different recovery ratio.
The results show that there is a good relationbetween slope rockmass quality(BYZ),which depends onrebound value(R),grip coefficient(E),apparent block size(D)and ground water(W),and slope height and angle.
A comparison with the experimental data of Shklovskii shows that the scale length of the spatial inhomogeneity a=3.7×10-6 cm at T=4.2 K corresponds to the average block size.
It is shown that the asymptotic dependence of the mean block size on time has the form R(t) ～ √t/lnt.
In the framework of an equivalent mathematical model combining the Ising and Kosterlitz-Thouless two-dimensional models, a kinetic equation that approximately describes the evolution of the domain-block size distribution function is derived.
The effect of low-angle boundaries on the dielectric properties of epitaxial Ba0.8Sr0.2TiO3 films is studied by comparing films differing in crystalline-block size.
The main factor determining variations of the unit cell parameter c in the films is the difference of the crystal block size ?D? in the direction normal to the film surface, which reflects the nanodimensional effects known in oxides.
