Our preliminary results find growth rates greater than previously observed by DIC microscopy. We can also measure the growth rate of bundles by observing a mass of fibers that subsequently grow along the channel, and these grow at rates comparable to those determined by DIC microscopy. Implications of the measurements and the method will be discussed.

In this paper, we compare Huffman coding and Arithmetic coding with ASCII coding to observe their contribution to steganography. This way is to compress the embedded information first for enhance the payload of a cover image. There are many wonderful coding methods to compress this kind of string, such as Huffman coding and Arithmetic coding. The experiment results indicate that Huffman coding and Arithmetic coding as an important preprocess step of steganography can effectively reduce the amount of secret information with efficient encoding performance. And a theory opinion related to payload calculation is proposed which can be used to describe the relationship among the three parameters of steganography: imperceptibility, information embedding efficiency and payload.

With the rapid development and widespread use of Internet, readers, especially scientific researchers, depend more on Internet than on traditional library services for necessary information. The Web access of libraries has begun to lay more emphasis on digital reference and consultation services. More importantly, this new type of service is becoming the focus of many scholars research at home and abroad. In this paper, we design a library digital resources management system based on the semantic Web technology, and analyze the access control model in our system by the semantic Web.
