    Abstract: The X-ray absorption fine structure (XAFS) is often used effectively to determine many structural parameters and dynamic properties of materials, so calculating the temperature-dependent XAFS Debye-Waller (DW) factor of metal crystals will be a necessary addition to the advanced material technique. In this work, the thermodynamic parameters are der... Show More

    Abstract: The process of inserting secret data in any media as pictures, audio, video, text and protocol, also it can be empathy this secret connection is called steganography. At present, the widespread use of internet applications has become a security risk. Steganography is used to overcome this undesirable situation. It shows a significant character in m... Show More
