For strengthen its visibility, we present color proportion method to distinguish cross poly- lines, central angle mapping method to exhibit information distribution, and axes are not changed equivalently showing the detailed information in the key area.

First we use multiresolution to construct seamless texture map, and unwrap the cylindrical projection of a general model mesh.

Standard circle map based on circuit model and its experiment study;

In this note,we mainly prove that the following conclusion is true not only for a circte map with a periodic point but also for a general circle map f.

Multi-domain access control policy model based on role mapping and PBNM;
