By combining techniques of digital image processing, geometry vectorization and automatic finite element mesh generation, a finite element model for mechanical computation can be obtained using this method.

In sharpening tool cutters there is a shortcut mainly based on the geometric shape,which is not only easy to learn, but also can be very precise.

States the method of improving the joint strength by analyzing and researching the excessive coordination of the shaft plug and chain plate, geometric shape and tolerance of plate hole and shaft plug, chain hardness and the pressure in the coordination of the chain joint.

The modulation transfer functions (MTF) of CCD array with equal sampling area but different geometric shapes of pixel are analyzed and simulated by the CCD sampling theory in the case of hexagonal and rectangular shapes.
