But its’ visual effect is poor because of digital models do not have material, textures, and other details without CG processing.
After adding details such as material and materials, the models are imported into Ngrain software.
Actual verification shows that materials and textures of original models can be retained better in this method.

Abstract We have detected defects micro-pipes and a cluster of impurities in semi-insulating
6H-SiC substrates using long-wavelength infrared thermal imaging camera (IR-camera) with 8 ~ 14
µm in non-destructive and non-contact.
However, in the 6H-SiC expected as the substrate material for high frequency devices, the practical crystal is under development.
The IR-camera detects and visualizes infrared light radiated from the materials.

There is no other material cost during this simple process[1].
Also, we do not need any other materials in the whole process, so it is a cost-effective anti-counterfeiting technology[2].
This is a way combined with the halftone image screening technology and optical reflection characteristics of the grating materials.
We can widely use this method in document protection because there is no other material cost during the whole process.

There are several key parameters in IMPACT function as followed:
(1)Stiffness K:material stiffness (to calculate the vertical force of the contact-impact model),its value depends on the impactor material and structural shapes
(2)The damping properties of contact materials
In this paper, two gears material is both used as 45 steel(U=0.3,E1=E2=2.1e+11Pa).The gear contact parameters calculated based on references are listed in Table 2.

With the implementation of Web Based KM System, the library would be able to create “Digital knowledge banks” at any place, which would include:
l Online published material: e-books, e-journals, government documents, handbooks.
l Digital publishing assistance: pre-print services, e-books, e-journal support, web site development and maintenance.
l Digital institutional repository: digital special collections, rich media (multimedia), data sets and files, theses/dissertations, faculty publications, pre-publications, working papers, educational materials, learning objects, course web sites, etc.
To digitize the materials brings implications and diverse complications.
