摘要：
The stability of discrete Hopfield neural networks not only has an important theoretical significance, but also is the foundation of the applications of the networks. Security of the algorithm is discussed.ANN originated has been applied in all aspects of life and production, especially in intelligent control, nonlinear function approximation and environmental parameters forecast assessment. Be similar to the human's brain mechanism, a neural network complete the tasks by the process of learning (training) and use (associative memories). Normally, the neural network can be assured used only after thorough study. According to the dynamic characteristics of the interconnections between nerve cells in Hopfield network, this paper discusses the application of Hopfield network model in gene diagnosis, points out the network problems and puts forward the solutions.

摘要：
In order to obtain unification between the robustness and invisibility of watermarking images, under the condition of the same quality of watermark, the more robustness of for anti-interference and noises in image processing can be obtained. Improved watermarking algorithm for color image based on quick block singular value decomposition is proposed. SVD transformation preserves both one-way and non-symmetric properties. This watermarking algorithm is purposed to embed the watermark by both of the U and D components of improved SVD. Experiments and attacks test show that the algorithm has good robustness. Furthermore, the extracted watermark can still be easily identified after tampering.
摘要：
We consider the problem of the correspondence leaning of two high-dimensional data sets via the manifold leaning techniques. It's convenient for us to find the shared latent structure of the high-dimensional data sets, if they can be aligned in a uniformed low-dimensional data space. A local affine technique to address this problem is present here. Our method preserves more geometrical knowledge of the high-dimensional data sets and can easily project the new test data into the aligned data space by the local transformation obtained during the training step. The effectiveness of our algorithm is validated by applying it to the problem of image sequences alignment.

摘要：
In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this paper, we propose a novel method to encrypt a gray image based on Arnold transform and Kent mapping. It is a digital medical image encryption algorithm, dual scrambling that based on chaos of pixel position and pixel values. The results of experimental and the statistical analysis show that the histogram of the encryped image is fairly uniform and significantly different from the histogram of the original image. The algorithm improves the traditional image encryption algorithm of image scrambling based on chaos, and it is valid and has good performance.

摘要：
With increasing the degree of state environmental protection, the comprehensive treatment of waste water containing stibium has become a new subject in stibium industry.In this study,we modified diatomite with calcium carbonate,and adsorptived waste water containing stibium using these modified diatomite.Then we explored the quality of modified diatomite,initial concentration,initial pH value,temperature and adsorpting time on adsorption. The adsorption isotherm of stibium fits Langmuir equation.The result shows that the modified diatomite has good adsorption on waste water containing stibium.

摘要：
This paper presents a novel image encryption scheme based on Arnold mapping and Logistic mapping.It is a digital image encryption algorithm,dual scrambling that based on chaos of pixel position and pixel value. First we separated the three channels of a RGB mode image, then transformed them into 3 two dimensional grey images. respectively scramblinged these gray images of the three colour channels or changed their gray value by different methods,finally combined the three ciphertext into a RGB mode image.The results of experiment simulation show that the key space is large enough to resist the brute-force attack,the ciphertext varies sensitively with any minimal changes of the initial secret key and the plaintext. The algorithm improves the traditional image encryption algorithm of image scrambling based on chaos, and it is valid and has good performance.
